Knowlede Complementarity Assessment
Program
Technical Abstract (Limit 200 words)
Intelligent Automation, Inc. will develop and
evaluate the "Knowledge Complementarity
Assessment Program" (KCAP), an automated
approach to assessing the effectiveness of
individual and crew/team training. KCAP is an
innovative combination of Latent Semantic Analysis
(LSA), a statistical procedure for text analysis, and
Intelligent Agents for Instruction (IAI), an
agent-based technology to optimize resource
selection for instruction. KCAP assesses individual
and team performance and training requirements;
evaluates the relative merits of training resources
to enhance each team members' knowledge and
performance for these requirements; and provides
adaptive, individualized training for each team
member, based on their role in a team. KCAP is a
context-independent, low-cost alternative to
domain-specific intelligent tutors. It can be used
developmentally (to monitor and plan training as it
progresses), summatively (to evaluate the team and
individuals at the completion of a sequence) and to
monitor learning retention over time. We will
explore new methods of using KCAP to assess
team members' training during their performance of
real tasks. These advances supports NASA in
evaluating training effectiveness for individual/crew
performance, and in reducing error in tasks such as
aircraft maintenance. KCAP can develop into an
affordable new training and assessment technology,
suitable for use in many operational environments.
Potential Commercial Applications (Limit 200 words)
The proposed work will result in development of a
powerful technology that will be effective and
efficient in providing methods to assess the
effectiveness of training for groups or individuals,
and to use that information to guide training
programs. Using the Web, small training programs,
without sufficient financial resources to conduct
significant evaluation studies alone could use
KCAP through a "fee-for-service website."
Another product/service will be providing
KCAP-based validations of performance based
assessments, which could be provided through the
Web or through typical commercial software
distribution mechanisms. These will complement
IAI's other education and training-oriented Web
services and products.

Project Title: Fatigue evaluation and countermeasures using real-time video analysis
Technical Abstract (Limit 200 words)
The feasibility of a system to measure blink rate, percentage eyelid closure, blink amplitude, and blink duration from real-time video analysis to detect operator fatigue and produce countermeasures will be evaluated. The system produces an alarm when the onset of fatigue is detected (or the eyes remain closed longer than a selected interval). An active pixel camera will be used to acquire video images of the operator's eyes. Active pixel cameras are produced by a relatively inexpensive CMOS fabrication technique that can produce both analog to digital conversion circuitry on the same chip, thus the active pixel camera can produce digital video that is usable directly by a computer with no intermediate video boards, etc. A compact computer system will process the video images using specially designed algorithms to detect and quantify features of the eye in real-time. An inexpensive and non-invasive fatigue monitoring system would have broad commercial applications in aviation and ground transportation. The interruption of the circadian cycle in space flight and long distance aviation, and the continuous state of alertness required during certain tasks make alertness and fatigue monitoring especially important in these situations.
Potential Commercial Applications (Limit 200 words)
An effective, low-cost, unobtrusive fatigue monitoring system has large commercial potential because of the scale of the problem. Such a system could be widely used in commercial aviation, space missions, and ground transportation. The technology has potential for low-cost production because it is based on low-cost standard hardware components with specialized software. Early adopters of this fatigue monitoring system would probably be groups who are at high risk for fatigue-related accidents because of the hours they work including astronauts, commercial airline pilots, air traffic controllers, and long distance truck drivers.

Project Title:
Collaborative Decision Making
Airspace Visualization Tool
Technical Abstract (Limit 200 words)
This effort will develop a collaborative decision
making visualization
tool that will benefit dispatchers at Airline
Operations Centers
(AOCs), aircraft flight crews, Air Traffic
Management (ATM), and
scientific researchers who are designing decision
support systems for
these decision makers. As new Free Flight
procedures remove jetway
routing, positive control, and other constraints, an
added emphasis
will be placed on collaborative ATM techniques and
distributed
control. Our innovation provides a visual tool for
monitoring
information and collaborating with a common visual
model. This tool
can assist in keeping track of aircraft, negotiating
conflict
detection and resolution options, observing weather
systems and
special use airspace constraints, and viewing
operations data - these
data are dynamic and originate from multiple
sources. Before any of
Free Flight changes take place, scientific
researchers can use this
tool to visualize solutions to problems associated
with the AOC, the
flight crew, and the ATM system. Additionally,
researchers may
visualize conflict detection and resolution results for
analysis, and
evaluate distributed systems concepts like
collaborative decision
making. This visualization tool will assist NASA
achieve effective
and safe control of multiple aircraft in the National
Airspace System
(NAS) through the visual integration of air and
ground-based air
traffic information.
Potential Commercial Applications (Limit 200 words)
The commercial potential for a collaborative
decision making system is
very high because (a) air traffic continues to grow
worldwide and the
demand for more timely, efficient, reliable air travel
is strong on
the part of the airlines and the traveling public; and
(b) the trend
in air traffic control is towards giving airlines more
and more
autonomy while maintaining safety. The FAA,
CAAs, airlines and other
fleet operators will require collaboration tools to
assist with
providing Free Flight operations.

Project Title:
Air Traffic Controller Agent Model for
Free Flight
Technical Abstract (Limit 200 words)
We propose to examine the human factors needs of
air traffic controllers operating under free flight
through the development of a modeling and analysis
tool based on an agent representation of the overall
controller/air traffic system. The approach relies on
a multi-stage agent-based representation of the
controller's SA and decision-making behavior, and
a multidimensional metric that reflects SA,
performance, and error propensity. We propose to
incorporate the controller agent into a simulated
free flight environment that contains a set of
semi-autonomous pilot agent models. Our objective
is to develop a simulation tool that will support the
development of rules and procedures for free flight
implementation, via simulation-based analysis of
controller behavior and airspace system safety
under alternate free flight configurations. One of
the key innovative features of the resulting free
flight simulation tool is a distributed
decision-making model embedded into the
multi-agent architecture, which will provide air
traffic management system designers with a basis
for the formulation of effective decision allocation
between ground control and pilots in free flight.
Potential Commercial Applications (Limit 200 words)
The proposed technology will directly support
closing the human factors loop on the development
of free flight ATM concepts. The underlying
modeling approach will also support human factors
assessments in other domains (e.g., nuclear power
plants, chemical processing centers, power dispatch
stations, intelligent vehicle highway system control
centers, etc.) where it is desirable to determine how
system design affects operator awareness and
performance before committing to a specific
configuration. We also plan to extract the belief
network algorithm that emulates air traffic
controller situation assessment in the presence of
uncertainty, and develop a commercial-quality
software tool for computer-based reasoning under
uncertainty.

Project Title: Integrated Ground Traffic Control (IGTC) System
Technical Abstract (Limit 200 words)
The overall objective of the technical effort proposed is to develop advanced innovative system design ("GROUNDTRAC") that will allow safe movement of ground vehicles and aircraft under adverse weather conditions at airports. Requirements and Hardware Implementation Designs will be developed for integrating and simultaneously controlling the surface movement of aircraft and airport support vehicles under adverse weather conditions. The problems associated with expanding to a large mixed fleet that involves simultaneous movement of aircraft and ground vehicles will be addressed. The technical effort to be performed will define system designs, modifications and system requirements that when implemented will allow compatible operation of ground vehicle navigation system with aircraft navigation systems such as those defined by the NASA TAP Program in 1997. These Systems must be integrated such that simultaneous control and operation of a large mixed fleet of vehicles from a Single Control Center can be achieved at Airports during adverse weather conditions. This proposed advanced system design effort will identify the system requirements, technical designs and technology developments needed to achieve this integration.
Potential Commercial Applications (Limit 200 words)
GROUNDTRAC has broad application at airports worldwide. By developing this integrated system design for near term deployment, NASA will help airport authorities and local government agencies avoid costly and time consuming redesign or retrofit that will occur when navigation systems used by aircraft and surface vehicle are implemented that are not the same and not compatible.

Project Title:
A Turbulence/Vortex Detection System
Using Optical Scintillation Techniques
Technical Abstract (Limit 200 words)
NASA, FAA, and U.S. Air Force have identified the
need to detect the aircraft trailing wake turbulence
generated by aircraft during take-off and landing
operations. At the present time, one of the major
problems of wake turbulence assessment is the lack
of an operational system to measure it in real-time.
As a result, FAA instituted operational and physical
guidelines to reduce the vortex wake hazard. These
conservative procedures put extra limits on airport
capacity and efficiency.
Scientific Technology, Inc. (ScTi) proposes to
develop a vortex/ turbulence detection system
including a set of scintillometers deployed in the
airport to measure ground and near ground runway
crosswind, turbulence, and wake vortex using
atmospheric turbulence- induced optical
scintillations. ScTi will perform system analysis and
design of the proposed system to detect
occurrences, location, magnitude, and persistence
of wake turbulence. With the simultaneous
measurements of crosswind and turbulence, the
sensor may even be able to forecast the arrival
time of the airplane generated wake vortex drifting
to a nearby runway. Successful development of the
system will serve as a decision support tool to ATC
for the next generation Air-Traffic Management
system to accommodate growth in air traffic while
reducing the aircraft accident rate.
Potential Commercial Applications (Limit 200 words)
Accurate crosswind, turbulence, and wake vortex
measurements are critical for improving airport
safety and efficiency. Successful development of
the proposed sensor technology will lead to the
large scale deployment of the proposed systems at
commercial and military airports around the world.

Project Title:
Navigation and Situation Awareness for
Landing and Runway Crossing
Technical Abstract (Limit 200 words)
Faced with a projected increase in air traffic in
excess of 30% in the United States over the next
decade, government agencies such as NASA and
the Federal Aviation Administration (FAA) are
developing advanced technologies to increase
traffic-handling capacity at existing airports. Efforts
to increase airport capacity approach the problem
on two fronts: the first obvious solution is to
increase the number of runways (i.e. quantity), and
the second approach is to develop new technologies
to achieve reduction in aircraft separation and
consequently a corresponding increase in landing
rate per runway (i.e. efficiency). Both approaches
have to be accomplished without compromising
safety. The first approach based on increasing
usable runways also imposes new technical
problems. Modifying an existing airport layout
increases surface traffic complexity with increased
volume of aircraft and surface vehicle traffic,
resulting in increased occurrences of runway
crossing. The innovations advanced in this proposal
include both automatic and manual control of the
aircraft for runway crossing that will be tightly and
seamlessly integrated with products currently being
developed under the NASA TAP program. In
addition, the proposed effort includes performance
and benefit analyses to identify the maximum
possible capacity impact, and the potential
achievable benefits from such technologies.
Potential Commercial Applications (Limit 200 words)
Like most of the products being developed under
the NASA Terminal Area Productivity program, the
technologies developed under this SBIR proposal
are targeted for civil aviation. As the global travel
volume increases and the major airports execute
their plans to increase capacity through expansion,
runway crossing will quickly become a major issue
at these airports. The technologies to be developed
under this SBIR will be useful for developing new
avionics systems for improving ground traffic.

Project Title:
SafePath for Airport Surface
Movement
Technical Abstract (Limit 200 words)
Safety and efficiency are primary concerns in the
planning and conduct of vehicle movement on the
airport surface area; yet in many areas of
transportation management and system logistics,
safety and efficiency are competing goals. During
this Phase I SBIR effort Wyndemere Incorporated
proposes to study a system that will meet these two
challenges in a complementary manner through the
development of a detailed plan for airport surface
movement. This plan, formulated through
constraint-based optimization methods to increase
efficiency, will also allow warnings to be issued
when vehicles deviate from the plan, rather than
when an incursion or incident is imminent. The
innovation proposed is the research and prototyping
of a constraint-satisfaction based algorithm for the
generation of efficient airport surface movement
paths. This innovation will provide the fundamental
technology for a complete decision support system
to increase both safety and efficiency in airport
surface movement, considering aircraft and other
airport vehicles during normal, low-visibility and
emergency conditions. This technology will fit well
with NASA's Surface Movement Advisor project
and the recent demonstration of the Low Visibility
Landing and Surface Operations program at
Atlanta's Hartsfield Airport.
Potential Commercial Applications (Limit 200 words)
Technology aimed at increasing the safety and
efficiency of airport surface movement is in rising
demand. The United States has set aggressive
goals for the reduction of the aviation accident rate
in general, and runway incursions in particular. It is
expected that significant investment in safety
improvements will be made by the US government
and international aviation authorities over the next
few years. For airlines and air cargo operators,
ground movement efficiency is a major cost
concern; potential losses from aviation delays
creates a strong market for technology and
products that can increase the efficiency of airport
surface operations. In this regard, Wyndemere has
been working cooperatively with Federal Express to
identify the characteristics of traffic flow, airspace,
airport layout and air traffic control procedures that
contribute to inefficiency in their air cargo
operation. FedEx is interested in supporting the
research, development and use of this proposed
technology at Memphis International Airport, and
in-kind contributions have been committed to
Wyndemere by FedEx to support this Phase I SBIR
study.

Project Title: In-Flight Icing Detection Radar
Technical Abstract (Limit 200 words)
NASA has a mission to develop real-time, in-flight, remote sensing of hazardous icing conditions, characterized by a super-cooled water droplet environment several miles ahead of the aircraft. Technology Service Corporation (TSC), with informal consulting from Mr. Robert Kropfli, NOAA/ERL, proposes to develop, test and demonstrate a dual frequency, differential attenuation radar for this mission. The radar is based on modifications to a commercial weather radar, operating with (a) an X/Ka-band single aperture antenna developed for NASA/LaRC, b) a commercial signal processor developed for NASA/ARC and (c) special waveforms and discrimination algorithms. The radar will also be used for data gathering to resolve technical issues identified during the 1991 Winter Icing and Storm Project, WISP91.
Phase I will conduct engineering analysis, performance predictions, algorithm development and a radar design. Phase II will integrate the differential attenuation technique into a commercial weather radar and field test the radar in both data gathering and concept demonstration modes out to 10 nmi.
The radar's form factor allows it to be installed directly into commercial aircraft and rotorcraft, thereby enhancing Phase III transition.
Potential Commercial Applications (Limit 200 words)
The benefit from this program, if successful, will be a practical solution to the aircraft icing detection/avoidance hazard that can be employed on most aircraft currently using weather radars. The applications range from commercial propeller-driven commuter/regional aircraft up to large jet airliners. Military applications include fixed-wing aircraft, RPV's and helicopters.

Project Title: Detection of Icing Through Aircraft Parameter Identification
Technical Abstract (Limit 200 words)
The proposed development will result in the DIDS system, designed to detect an icing problem onboard an aircraft in flight from real-time identification of degradation in key aircraft dynamic characteristics and aerodynamic parameters. This will be implemented using cross-spectral methods to generate frequency response characterizations of aircraft input/response relationships. Icing will be detected from changes in a suite of characteristics and parameters over time. Icing degradations of key longitudinal parameters will be estimated including: drag coefficient, lift coefficient and lift curve slope, static margin, elevator effectiveness and elevator hinge moment for aircraft with reversible mechanical primary flight control systems. Lateral-directional dynamics would be considered in Phase II. Icing detection from the DIDS system would ultimately be fused with onboard ice detection sensor data and off-board meteorological data to improve the overall resolution, accuracy and reliability of advisories to the pilot. A primary innovation of the DIDS system is the direct estimation of aerodynamic parameters most fundamentally related to icing phenomena and to aircraft stability and control. A related innovation is the use of established flying qualities criteria to integrate the degradation estimates into a severity metric for the pilot.
Potential Commercial Applications (Limit 200 words)
The DIDS system will be marketed as a product together with related, highly technical, consulting services. The consulting services may range from training the customer in the use of the DIDS system to continually assessing and improving its effectiveness. The initial customer target will be the airline and business aviation sectors of the industry. Emphasis will also be placed on demonstrating the effectiveness of the system to the Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) with a view towards having the DIDS declared as a mandatory system on air carriers. We anticipate that the airlines as well as the FAA will require our consulting services to refine the software based on their specific requirements and practical needs. We anticipate an initial market penetration into the commuter airline and business aviation industry where the safety hazards due to icing are the greatest. There has been a rapid growth in the commuter airline industry following the adoption of the "hub-and-spoke" method of operation of the major airlines. There has also been rapid growth in the business aviation industry in recent times.

system for verifying digital electronic hardware
systems. The system addresses the problem of
verifying gate- or register transfer-level design
models against abstract specifications represented

feature automated construction of the proof steps
required by existing mechanical proof checkers.
The proposed research addresses elements of
NASA subtopic 01.04, Reliable and Safety-Critical
Software, by constructing
automated tools to support developing
safety-critical systems. The objective of the
proposed research is to develop a verification
system into an advanced prototype suitable for beta

completion of this goal would go a long way in
moving the electronics design industry towards
methods of greater rigor and automation.
Potential Commercial Applications (Limit 200 words)
The main commercial applications for our proposed
work are electronic design automation (EDA) tools
for digital hardware design and verification. The
commercial potential for tools offering this
combination of automation, verification speed, and

Project Title: Real-Time Equipment Analyst & Monitor
Technical Abstract (Limit 200 words)
AbTech Corporation proposes to apply its unique statistical network data mining technology to develop a real-time diagnostic and on-line health monitoring product for equipment that automatically 1) analyzes equipment operational performance data, 2) learns and models the expected characteristics of specific equipment sensor data, parameters, and failure modes using AbTech's advanced data mining technology, and 3) applies these learned models onboard and on-line to monitor and predict the health of equipment components for "just in time" maintenance and to identify unexpected values and concerning trends in current equipment performance.
The proposed system, called the Real-Time Equipment Analyst & Monitor (RTEAM), will be able to identify and interpret complex relationships in equipment behavior to substantially reduce the likelihood of incipient failures and performance degradation being undetected until they cause significant damage to critical equipment components. RTEAM will automatically analyze expected versus actual values of specified sensors, and provide indications of the significance of the differences (i.e., probability of anomaly). It will automatically learn how to detect and isolate anomalous equipment behavior based on operational performance data.
The objectives of this effort are to prototype RTEAM and to demonstrate its exceptional potential value for a selected aircraft or spacecraft application.
Potential Commercial Applications (Limit 200 words)
A major goal of this program is to enable RTEAM to be implemented and adapted to equipment hardware so inexpensively for the value offered that it will quickly become popular on many different commercial aircraft and aerospace applications as well as other mission-critical machinery subsystems and structures.

Project Title: Aircraft Integrity Radio Network Evaluation Technology (AIRNET)
Technical Abstract (Limit 200 words)
The advancing age of the U.S. commercial and military aircraft fleets pose increasing challenges to those personnel involved in insuring reliable aircraft maintenance and safety. Replacement costs and price competition encourage aircraft life extension. Current safety records indicate success with failure management. However, aging aircraft, inspection cost reduction, and recurring air carrier accidents demonstrate room for improvement. An airframe integrity monitoring system is needed that will provide constant inspection. The system is a multi-sensor, radio frequency, store-and-forward relay communications network capable of monitoring in-flight aircraft performance. Data from wireless sensor nodes installed throughout the aircraft is stored on a central communications node and is then transferred to an air-to-ground radio link. Ground stations are connected to telephone communications switches that provide data routing anywhere in the world. AIRNET data outputs would be switched to Internet web-sites. Condition-based maintenance (CBM) algorithms process data as it is collected in each of the sensor nodes. With such a system available, measurements and critical flight data are available that were previously restricted by installation complexity and cost. Because CBM technology is still in infant stages of development, the proposed system would also make raw data available to researchers in the business of algorithm development.
Potential Commercial Applications (Limit 200 words)
Invocon, Inc. is working with several large manufacturers of heavy equipment (earth moving) to define wireless systems that could eventually display vehicle health on the Internet. These companies feel the need to increase the level of service and product maintenance and thus are motivated to acquire data on the performance of the vehicles as they operate on a day to day basis. This not only requires wireless sensors at the data collection points, but also the low cost data transmission capabilities of the common user dial-up phone networks. As the Internet grows in acceptance as well as capacity, it too offers commercial data monitoring at attractive prices.
Manufacturing processes also benefit from conditioned based maintenance (CBM) data generated from wireless data acquisiton. Wiring in heavy manufacturing environments increases sensor monitoring hardware costs to prohibitive levels. Installation flexibility in a manufacturing arena is important for quick re-configuration of machines and processes. Integrated CBM data acquisition sytems can provide warning of impending failures in areas where the failure may leverage huge costs due to assembly line shut-downs. It can also provide tighter integration of the manufacturing processes by moving information from the factory floor to central points of analysis and decision making.

Project Title:
Wave Turbine Engines: Improvements
to an Existing Wave Turbine Test
Platform
Technical Abstract (Limit 200 words)
Wave rotors are a key technology to enable
significantly increased gas turbine peak
temperatures. Higher specific power results,
providing a more compact unit with the additional
benefit of increased efficiency. These benefits are
realized especially for small gas turbines since
self-cooling is a fundamental feature of the cycle.
Self-cooling is especially applicable to the
improvement of auxiliary power units (APU's) and
small turboshaft engines. Because the expansion
and compression processes occur on the same
rotor, part count and engine complexity is reduced.
The objective of the proposed research is to
determine the requirements for upgrading an
existing wave turbine and, in Phase II, fabricate and
test the resulting upgrades. The primary goal is to
design for improved start-up operation, addressing
an important issue in wave rotor engines. This wave
turbine, the only known operating engine of its
class, was recently resurrected, meticulously
characterized, and partially tested to determine
problems, limitations, and requirements for
continued research. The proposed approach will
minimize the time and cost of developing this timely
technology for improving the APU's specific power,
efficiency, and simplicity. The upgraded

Project Title: Mixed-Compression Inlet for Supersonic Cruise with High Performance and Operability
Technical Abstract (Limit 200 words)
This proposal identifies a new supersonic inlet design. It introduces a unique mixed- compression inlet concept with very high performance, increased safety by maintaining large operability margins, reduced weight/complexity, and a large transonic airflow capability. Each traditional inlet design concept has a deficiency in at least one of these characteristics. A new variable geometry scheme enables a breakthrough in axisymmetric inlet design that offers a large transonic flow capability. This proposal responds to the SBIR research subtopic by proposing a invention in inlet design that will enable the development of a commercial supersonic aircraft. The objective of the effort is to provide a preliminary aerodynamic design of the new inlet, a conceptual layout of the inlet and variable geometry scheme, and an analysis of the aerodynamic capabilities of the new inlet. It is expected that this Phase I effort will identify and deliver a revolutionary new inlet that will be selected for both experimental and analytical validation in a follow-on SBIR Phase II. This revolutionary advance in inlet technology will enable the development of an efficient and safe propulsion system for a US high speed civil transport (HSCT). This type of enabling technology is the goal of NASA's HSR Program.
Potential Commercial Applications (Limit 200 words)
The commercial application of the proposed new inlet design is based on the expectation of achieving very high inlet performance while maintaining the desired operability margins, reduced weight, and sufficient transonic airflow capability. The increased efficiency and versatility provided by the proposed new inlet concept will enable the development of a propulsion system for a supersonic aircraft that offers increased range, payload/profit, and safety. Commercial applications include aircraft used for transportation of people and packages throughout the world.

Project Title:
Active Combustion Control Using
Micro-Fabricated Sensors and Actuators
Technical Abstract (Limit 200 words)
Physical Sciences Inc. (PSI) proposes to develop a
closed-loop combustion control system for gas
turbine engines utilizing micro-fabricated sensors
and actuators. In previous and on-going work, PSI
has demonstrated the feasibility of active control
systems to suppress combustion instabilities and
improve combustor pattern factor, both of which can
lead to improved engine performance and
efficiency. The primary motivation for incorporating
micro-fabricated components into the system design
is to achieve a compact and highly-integrated
control system which is compatible with the size and
weight constraints of operating within a gas turbine
engine. Additionally, micro-fabricated components
have the potential to provide improved performance
over their macroscopic counterparts, allowing a
wider range of control strategies to be
implemented. PSI proposes to integrate a
micro-fabricated valve directly into a commercial
gas turbine fuel injector for active fuel flow control.
Additionally, strategies for actively controlling
spray patternation with embedded micro-actuators
will be developed. The active fuel injector designed
in the Phase I program will be fabricated and tested
in the Phase II program as part of an overall
combustion control system.
Potential Commercial Applications (Limit 200 words)
Successful development of the proposed technology
will represent one of the first commercial insertions
of micro-fabricated sensors and actuators in gas
turbine engines. A higher level of control over the
operation of gas turbine combustors will be
achieved with the proposed system, and along with
it, improvements in engine performance and
efficiency over the entire life of the engine. The
micro-actuator and sensor based combustion
control system also has the potential to lower the
costs of gas turbine engine development by relaxing
some of the constraints on the combustor design
process.

Project Title: Smart Coatings for In-Situ Monitoring of Engine Components
Technical Abstract (Limit 200 words)
Fatigue cracking and plastic deformation occur in both new and aging aircraft engines requiring periodic manual inspections with ultrasonic and eddy current robes. Often cracking occurs in inaccessible areas which require engine disassembly just to perform the inspection. In many cases, the cost of is assembling/reassembling the engine far exceeds the cost of inspection and can also induce new damage.
IDI will address this problem by developing Smart Coatings - under 10 micron thick coatings that contain planar sensors sandwiched between layers of tough protective insulators. By directly depositing these Smart Coatings onto the part, you add a life-extending protective coating that also performs important structural sensing.
During Phase I IDI will work with Cornell University's National Nanofabrication Center to develop Smart Coating eddy current sensors for detecting cracking and plastic deformation in metals. We will use standard deposition, sputtering, and photolithography methods to deposit gold/silicon nitride sensor patterns onto steel coupons, and then will destructively test those coupons to quantify their sensitivity to stress and fatigue-induced damage.
Potential Commercial Applications (Limit 200 words)
Military and commercial aircraft fleet operators could immediately use this technology to create tailored embedded sensing solutions to known engine maintenance problems. When coupled with emerging technology for depositing thin diamond films on 3-D surfaces, one could add embedded sensing to virtually any mechanical part, such as turbine blades, bearing races, and hydraulic valves.

Hi Temp.Fiber Optic Eng.Mtd.
Ceramic Press. Transducer
Technical Abstract (Limit 200 words)
The demand of advanced aircraft propulsion
systems on sensor technologies to operate at
extended
temperature ranges has to date been primarily
focused on redesigning existing measurement
system
techniques. This proposed program will show the
feasibility of a new remote fly-by-light technology
made
possible by the availability of high temperature
air-clad sapphire optical fibers. The LEL concept
for
applying this technology to pressure and related
measurements is electrically passive-optically
active. No
electrically active parts reside in the sensor,
minimizing temperature effect on the sensor output.
The
sensor's input and output optical fibers can be
integrated in the engine's composite structure or
passed
through traditional wire ways to traditional
electronic components which are located remotely
from the
sensor. A primary feature of this new sensor design
concept is to measure differential motion as
opposed
to absolute motion, typical of diaphragm designs. A
properly designed differential motion sensor
measures only the input parameter not the side
effects caused by temperature and induced
stresses,
both static and dynamic. This fiber optic
miniaturized ceramic transducer is "Thermally
Hardened" by
material modifications allowing it to operate in a
high temperature (1000 degrees C) environment. It
does
not require active temperature compensation or
linearization to achieve specified accuracy.
Potential Commercial Applications (Limit 200 words)
The disclosed pressure transducer will provide an
essential input to an engine monitoring system
for the prediction of engine maintenance and stall.
In addition, this sensor technology can be used by
industries such as oil drilling, petrochemicals,
hydraulics, heavy construction equipment,
geothermal, geopressure wells, metal cutting, oceanography,
nuclear power plants and research organizations,
with similar gains in performance and reduced cost.

Project Title: LWIR Microthermopile Aircraft Engine Monitor
Technical Abstract (Limit 200 words)
NASA has a need for integrated sensors and controls utilizing Micro Electro-Mechanical Systems (MEMS). Of particular interest is the quantification of OH, NOx, CH, CN, formaldehyde, free radicals, and small molecules in aircraft exhaust. Current technology based on Laser Induced Fluorescence (LIF) is only capable of identifying one species at a time and in a single direction. An on board exhaust monitor capable of quantifying multiple species, in multi-directions, with full IR spectra would enable real time determinations of engine health and enable feedback control.
In ongoing Phase II SBIR programs with NASA, Ion Optics has developed a spectrometer-on-a-chip which provides mid-wavelength infrared spectroscopic gas analysis in a lightweight, miniaturized, and vibration resistant system. To address NASA's needs we propose to adapt our spectrometer technology to JPL's high performance uncooled linear MEMS detector arrays, and an advanced low-noise readout multiplexer to enable long-wavelength IR (8-14mm) analysis of aircraft exhaust. The integration of these three advances will provide a high ensitivity, low power consumption instrument which is small enough for onboard propulsion monitoring and control. Ongoing projects have demonstrated technical feasibility of these three key components and set the stage for development, integration, and validation of an onboard monitoring system.
Potential Commercial Applications (Limit 200 words)
A small, lightweight, and rugged sensor capable of identifying and quantifying chemical species in the long wavelength regions of the infrared would have widespread commercial appeal. Such a sensor system could be immediately applied to compliance monitoring on commercial aircraft. Additional applications include adaptation to on board analysis of automobile exhaust, smoke stack monitoring, and chemical process control.

Project Title: Quantitative Combustion Diagnostics for Fuel Sulfur Oxidation in Jet Engine Combustors
Technical Abstract (Limit 200 words)
Quantitative combustion diagnostics are needed to study the fuel sulfur oxidation chemistry in jet engine combustors which affects aerosol loading in the atmosphere. Absolute concentration measurements of key combustion radicals and intermediates provide a platform to validate the current sulfur oxidation model and to predict the aerosol loading by jet engines. Current laser-based combustion diagnostics exhibit high spatial and temporal sensitivity, but they often yield relative concentration profiles especially under high pressure conditions due to extreme sensitivity to changes in collisional quenching. We propose to develop a spatially resolved, high sensitivity quantitative combustion diagnostic based on a novel tunable UV source that is compatible with high pressure and high temperature combustor conditions. The tunable UV source, based on nonlinear upconversion of a tunable diode laser beam with fixed frequency radiation, will be used to perform line-of-sight high sensitivity absorption and laser induced fluorescence (LIF) measurements simultaneously. In Phase I, we target spatially resolved concentration measurements of OH in laboratory flames for the feasibility demonstration. In Phase II, we plan to extend the UV wavelength coverage to include other key species relevant to sulfur oxidation chemistry including SO2, and to validate the measurement approach through a series of jet engine combustor measurements.
Potential Commercial Applications (Limit 200 words)
The proposed technology will be useful as a quantitative combustion diagnostic tool in development of rocket and jet engines, turbines, and wind tunnel combustion facilities. The tunable UV source developed in this project will also be useful for environmental monitoring of many important trace species emitted by power plants, municipal incinerators, chemical plants, and oil refineries.

Technical Abstract (Limit 200 words)
A catalytic lean direct injection (LDI) design is a
practical approach for achieving NOx emissions
reduction for the Advanced Subsonic Technology
(AST) combustor. Our novel catalytic LDI design
integrates the underlying catalytic combustion
principles behind Precision Combustion's prior lean
premixed prevaporized(LPP)designs with effective
LDI principles applied to liquid fuels. This combines
the benefits of LDI, including avoiding preignition,
with the improved stability and ultra-low NOx
emissions of catalytically stabilized combustion.
Catalytic enhancement of flame stability offers
potential breakthroughs for NASA's advanced
subsonic program gas turbine engine through very
low pressure drop, high inlet duct velocity, high
turndown and stability, and low NOx at pressure.
Potential Commercial Applications (Limit 200 words)
High efficiency and low emissions are twin
objectives of future aerospace gas turbine engines.
This design approach contributes to these
objectives by enhancing stability, mixing, and
turndown of Lean Direct Injection Designs, offering
design flexibility to engine designers. This
combustor is being developed with a focus upon
ease of implementation into engine manufacturers
Advanced Subsonic Technology combustors

Rotorcraft Blade Vortex Interaction
Control with Induced-Strain Actuation
of Blade Twist
Technical Abstract (Limit 200 words)
Systems Planning and Analysis, Inc. (SPA)
proposes to develop a Mach-scaled smart
helicopter rotor with on embedded piezoceramic
elements for blade-vortex interaction (BVI) noise
reduction. SPA will use directionally attached
piezoceramics as actuators and sensors, for
closed-loop higher harmonic pitch control of the
main rotor blades. These pitch perturbations will
generate unsteady blade loads that would in turn
counteract loads generated by the BVI, with little
impact on the nominal steady-state rotor thrust. In
the proposed Phase I effort, SPA will use
Euler/Navier-Stokes computational fluid dynamics
(CFD) codes as a Òvirtual experimentÓ to examine
the 3-D interaction of a simplified vortex system
with a rotating blade (for low-speed descent flight)
and the associated aeroacoustic noise to establish
the required performance metrics (i.e., blade twist
deflection, actuator power, frequency response,
etc.) to reduce BVI by 10dB. The calculated leading
edge pressure differentials at several spanwise
stations in the outboard (60 to 90 percent of span)
region of the blade will be used as inputs to simple
control algorithms for determining the appropriate
twist actuation required for BVI noise suppression.
Finally, the CFD calculations will be repeated with
the variable twisting actuation to determine the
actual noise reduction achieved.
Potential Commercial Applications (Limit 200 words)
The successful development of a smart rotor
system will offer unprecedented benefits to military
and commercial rotorcraft. Reductions of BVI and
low frequency rotor noise (and the associated
higher-harmonic rotor vibrations) will reduce the
detectability of military platforms during Nap of
Earth (NOE) operations, while improving the rotor
performance for air-to-air combat. For commerical
rotorcraft, reductions in rotor noise would allow for
operation in urban environments with aircraft noise
restrictions. Furthermore, the reduction of harmonic
blade loads would reduce the maintenance
requirements and associated high cost of all
rotorcraft systems subject to premature failure of
rotor components due to high dynamic stresses.

Project Title: Autonomous Far-Field Cancellation of Broadband Noise from Ducted Fans
Technical Abstract (Limit 200 words)
We propose to show that two new active control algorithms can reduce the noise radiated from a ducted fan by more than 10 dB in the far-field. This demonstration will provide strong evidence that the difficult noise standards of FAR 36, Stage 3 will be attainable, at least in part, with active control, at substantially reduced cost and performance when compared with passive methods alone. The two new algorithms we propose to apply have the following features, which together constitute a new, enabling capability for the control of broadband and tonal fan noise in the far field: they automatically account for feedback from the control actuators to the disturbance reference microphones; they control multiple duct modes in a coordinated fashion; they adapt on-line to changes in the system dynamics over flight conditions; and they perform their computations in a particularly efficient manner due to the small number of parameters required by their system representations. The existence of two highly relevant, already funded efforts makes it possible to demonstrate feasibility within the funding and time constraints of Phase I: one which makes key measurements on a NASA noise control testbed, and another which develops the theory for the algorithms.
Potential Commercial Applications (Limit 200 words)
The specific product that will be developed with this SBIR effort is a fully adaptive, autonomous controller for multiple-input, multiple-output systems in which there is significant feedback from the actuators to the disturbance sensors. This product can be applied to many different structural or acoustic control problems, including: ducted fans for aircraft transport propulsions, low-noise propulsors for submersible vehicles, commercial and industrial cooling and ventilation fans and ducts, and almost any lightly damped structure in which motion can be sensed for later cancellation. Initial development will focus on high-valued systems, such as aircraft engines and submarines, where there is a large financial incentive for noise reduction.

Advanced Prediction Tool for

Sources
Technical Abstract (Limit 200 words)
Serious concerns regarding the adverse
environmental impact of aircraft noise have led to
increasingly stringent regulations on the allowable
acoustic emissions from commercial transport
aircraft. To facilitate future growth in air
transportation while ensuring compliance with
international noise regulations, urgent attention to
noise prediction and reduction technologies is
required at this time. The perceived aircraft noise
levels during both takeoff and approach phases are
controlled by the turbomachinery noise, in
particular, its fan component. Here, an accurate yet
highly efficient numerical technique based on a
(high-order) computational aeroacoustics (CAA)
algorithm is proposed for simulating
turbomachinery noise. This approach is innovative
in tapping the potential of CAA to provide an
enhanced physical understanding of and integrated
prediction methodology for turbomachinery noise.
In addition to providing guidance and checks for
preliminary design tools, simulation tools of this
kind will minimize the overall design cycle time and
significantly enhance the competitiveness of U.S.
engine manufacturers in the global aviation market.
Potential Commercial Applications (Limit 200 words)
Turbomachinery design, engine noise reduction

Active Control of Broadband
Rotor/Stator Noise in Turbofan
Engines
Technical Abstract (Limit 200 words)
The proposed innovation is a compact active control
system for reduction of tonal and broadband noise
radiated by rotor/stator interaction in turbofan
engines. The concept employs pressure transducers
on stators (outlet guide vanes) to capture signals
correlated with radiated noise. The signals are
processed and distributed to circumferential arrays
of actuators that serve as anti-sound sources to
cancel the rotor/stator noise. Circumferential
arrays of sensor microphones provide error signals
for the adaptive control system. Correlations
between stator vane fluctuating surface pressures
and radiated noise will be measured in the
NASA/LeRC ANCF fan to assess the feasibility of
the concept. Favorable results will lead to a
computer simulation of a simple active noise control
system and implementation of an in-situ
demonstration on the ANCF fan.
Potential Commercial Applications (Limit 200 words)
If successful, the proposed active noise control
system would suppress the lower frequency
(between 0.5 and 1.5 BPF) range of rotor/stator
noise. This would allow passive engine liners to
more effectively target high frequency noise in the
2 BPF to 4 BPF range and to be shallower, taking
less space.
The design concept of the system is such that the
actuator arrays could be integrated with active
control systems directed at tones.
There may be non-aircraft applications for the
concept, such as compact silencers for industrial
axial flow fans commonly used for air exhaust in
power generation systems, mining, parking
garages, etc. where personnel or community noise
exposure are often critical issues.

Low-Cost Surface Treatment for
Bonding Titanium Panels
Technical Abstract (Limit 200 words)
High speed travel requires reliable airframe
structure and low-cost fabrication technology.
Current adhesive joining methods for Ti panels are
not cost-effective. The resultant junctions are also
limited by the operating temperature under 430K
and the lack of long-term durability. This project
will develop new surface treatment processes to
create unique surface texture and chemistry for
strong and durable bonding with advanced
high-temperature adhesives. Phase I will
demonstrate the feasibility of two physicochemical
surface treatment processes to produce strong and
stable adhesive bonding for Ti panels. Phase II will
select one or two promising processes to optimize
performance, uniformity and cost effectiveness.
These surface treatment processes will be applied
to both monolithic and composite materials, and
titanium and other high-temperature metals, to
achieve a greater thermal stability of adhesive
bonding. Phase III will involve the development of
practical treatment procedures and equipment for
small-scale applications.
Potential Commercial Applications (Limit 200 words)
Physicochemical treatments are needed to prepare
stable metal surfaces for high-temperature
adhesive bonding. High performance and durable
adhesive bonding resulting from these new
processes could be used in high-temperature
aircraft and ground transportation applications. By
using little or no hazardous chemicals, these
processes could also reduce environmental
concerns associated with the use of hazardous and
toxic chemicals.

Variable Cell Blanket Sandwich Panel
Technology
Technical Abstract (Limit 200 words)
This project's purpose is to determine the viability
of mathematically modeling the load transfer
properties of uninterrupted variable cell blanket
structures. Variable cell blanket sandwich panel
technology integrates varying density areas into a
laser welded expanded honeycomb core structure
without the need for costly core splicing. The fully
integrated varying cell blanket configuration
creates an uninterrupted load transfer from one cell
size to another.
This effort will consist of the physical testing and
mathematicaly modeling of the properties of
samples of laser welded titanium honeycomb core in
a variety of cell sizes, and foil thicknesses. It is
anticipated that a viable approach to the modeling
of variable cell blanket structures will be
developed. This approach will be the model used in
designing low cost titanium sandwich panel
fabrications.
Variable cell blanket sandwich panels offer reduced
weight, lower cost and higher strength over other
fabricated panel structures. NASA and the
aerospace industry will benefit for this improved
structural design concept. Complex aircraft designs
requiring both low weight and strength can utilize
this technology to stay within their design
parameters.
Potential Commercial Applications (Limit 200 words)
Initially, the aerospace industry, both commercial
and military, will receive the greatest benefit from
variable cell blanket technology. Variable cell
technology offers decreased cost, decreased weight
and increased strength for all honeycomb sandwich
structures. There are a number of commercial
markets that will potentially benefit from this
technology. It is expected that the significantly
lower cost and flexible design possibilities afforded
by this product will encourage the use of
honeycomb in industries such as automobile,
construction, and shipbuilding.

the successful synthesis of polyimides via extrusion
like melt processes with resin properties equal or
better than traditional routes and suitable for low
cost fabrications. NASA and the aerospace industry
have significant demands for high performance
polyimides in the need to replace metal components
with light weight composites. Polyimide powders are
becoming more desirable to prepreggers as stricter
environmental regulations are being enforced. In
addition, solvent free polyimides are needed in
various fabrication techniques both by NASA and
the aerospace industry. These techniques include
Advanced Tow Placement (ATP) and Resin
Transfer Molding (RTM). The anticipated results
of polyimides made this way are better composite
properties due to absence of residual solvents and
better wet out because low molecular weight
polymer chains are not extracted.
Potential Commercial Applications (Limit 200 words)

Project Title:
Reducing Cost, Weight, and NOx of
Combustors by Incorporating Novel
Mixing Techniques.
Technical Abstract (Limit 200 words)
This program introduces novel mixing techniques
for supersonic transport propulsion low emission
combustor designs to dramatically reduce cost,
weight and complexity and to improve performance.
This innovation employs advanced multi-staged
lobed mixers to very rapidly mix fuel and air, both
temporally and spatially, with minimum momentum
loss to the flows. In demonstrations for other
applications, the concept has proven to improve the
transition from air/air mixing to liquid/air mixing.
This proposed work builds upon and extrapolates
the existing body of knowledge to develop a
predic-tive model for the HSCT combustor
environment. The Phase I results will be an
analyti-cal proof-of-concept, characterization of the
anticipated benefits and generation of mixer
designs suitable for verification testing in Phase II.
This program targets the de-fined Subtopic need for
environmentally and economically compatible
improvements directed at combustors for
supersonic transport propulsion systems.
Potential Commercial Applications (Limit 200 words)
The proposed multi-staged-lobe-mixer devices can
find commercial application in a multitude of
aerosol spray devices where a liquid must be
dispersed into a co-flowing, non-reacting gas
stream. Applications include air/fuel mixers for
supersonic transport propulsion systems in addition
to other flight and land-based gas turbines. Other
appli-cations which will be pursued include paint
sprayers, humidifiers and, snow making de-vices.

A MULTI-SPECTRAL AIRBORNE
RADIOMETER FOR RANGE
RESOLVED HIGH-ALTITUDE AIR
TEMPERATURE MEASUREMENTS
Technical Abstract (Limit 200 words)
Precise air temperature measurements currently
can not be made from high-speed aircraft. We
propose to solve this problem by using a
remote-sensing radiometer. The High-altitude Air
Temperature Radiometer (HATR) will operate in
the 15um CO2 absorption band, near the peak of
the thermal emission for stratospheric air
temperatures. This wavelength region has not been
used for commercialradiometers but has been
explored at Ophir. Using multispectral polarization
modulation and detection techniques, combined with
Ophir's experience and innovations in radiometer
design, we will minimize errors from housing and
window thermal radiance thereby permitting
accurate air temperature measurements on high
speed/high altitude aircraft such as the High Speed
Civil Transport. The unique design will enable the
radiometer to measure true air temperature out of
aircraft traveling at Mach 2.4 at altitudes up to
20km with 0.3C precision, corresponding to a Mach
number uncertainty of 0.002. These air temperature
measurements will be needed for precise control
ofsupersonic engine operation to maximize fuel
efficiency. A multiple wavelength design will allow
prediction of upcoming air temperature variations
to prevent engine unstarts.
Potential Commercial Applications (Limit 200 words)
Potential Commercial Applications
The proposed radiometer will enable accurate air
temperature measurements from high-speed
aircraft and could become an important component
of the HSCT program. In addition, range-resolved
temperature measurements will warn of potential
engine unstart conditions.
The proposed radiometer may find an immediate
market on commercial aircraft providing warning of,
and possibly permitting avoidance of, clear air
turbulence. Additionally, it may allow detection of
approaching icing conditions.

Project Title: Development of a SiC/SiC Ceramic Composite Combustion Liner and Other Components
Technical Abstract (Limit 200 words)
Refractory Composites, Inc. (RCI) proposes a ceramic composite hydrocarbon ueled gas turbine combustor development program in which advanced ceramic composite materials are developed in experimental combustor liner composite configurations and experimentally evaluated. In Phase I, RCI will fabricate and test a baseline SiC/SiC combustor and demonstrate an advanced transpirationally cooled CMC configuration. By tightly coupling composite materials development and combustion based evaluation, rapid, inexpensive and realistic assessments of CMC performance status and key composite improvement needs can be obtained.
During Phase II, RCI plans to address long life performance issues such as interface degradation and silicon monoxide vaporization damage under realistic combustor conditions. The process and composite constituent improvements needed to meet those challenges will be incorporated into Phase II combustor liner test articles for rapid assessment and repeated composite development cycles. By the completion of Phase II, RCI expects to advance at least 4 CMC composite generations and achieve comparable or superior durability and operational condition performance to the Si rich SiC/SiC materials presently being eveloped.
Potential Commercial Applications (Limit 200 words)
Both supersonic and subsonic (reduced emissions) commercial transport gas turbine engines will benefit greatly from the development of ceramic composite combustors and other stationary hot engine component applications. The commercial jet industry is the largest export income generating industry in the U.S.A. These enabling CMC technologies will allow us to maintain our dominance of the international market.

Project Title:
LOW NOISE EXHAUST NOZZLE
FOR A HIGH FLOW,LOW
PRESSURE HSCT ENGINE
Technical Abstract (Limit 200 words)
Environmental acceptability and economic viability
are crucial issues in the development of the next
generation HSCT (High Speed Civil Transport) and
low noise exhaust nozzle technology has a
significant impact on both issues. The design noise
level requirement for the next generation HSCT is
the FAR36 Stage III subsonic rule, with margins.
Since the propulsion system jet is nearly the sole
contributor to the community and sideline noise, the
technology for low noise exhaust nozzle is key to
the HSCT environmental acceptability. To be
economically viable, the low noise exhaust nozzle
must be simple, light weight, and have good
aerodynamic performance throughout its operating
range. A simple axisymmetric plug suppressor
nozzle is presented that reduces the jet velocity at
takeoff, to meet FAR36 Stage III noise levels,
including margin requirements; delivers high
specific thrust at transonic and supersonic cruise;
and delivers high nozzle efficiencies (greater than
0.95), for high performance, at takeoff, transonic
acceleration, subsonic and supersonic cruise flight
conditions. A conceptual design study is proposed
to investigate a low pressure axisymmetric
suppressor nozzle. The conceptual design will
address acoustics, aerodynamic performance, and
mechanical design requirements, as well as their
effects on aircraft takeoff gross weight (TOGW), of
FAR36 Stage III compliance and good nozzle
performance.
Potential Commercial Applications (Limit 200 words)
This effort will provide conceptual design of a low
pressure, axi-plug suppression exhaust nozzle for a
high flow, low pressure (VFX) engine concept. The
proposed nozzle concept utilizes proven suppression
technology that will reduce jet noise, provide good
aerodynamic performance, while save nozzle weight
and reducing mechanical complexity. When applied
to a HSCT or supersonic aircraft, the proposed
exhaust nozzle in conjunction with a VFX engine
cycle has a unique advantage over MFTF engine
cycles using ejector/suppressor nozzles, in its ability
to meet FAR 36 Stage III noise requirements, with
margin, at takeoff conditions.

Project Title: Innovative Affordable Head-Mounted General Aviation Pilot Information System
Technical Abstract (Limit 200 words)
AVROTEC will research emerging current-off-the-shelf technologies and develop preliminary designs for an innova-tive affordable head-mounted pilot information system for small general aviation aircraft. This system will incor-porate a light-weight, small form factor (but full "page") display with a voice command and aural communication system in a single comfortable, non-view-limiting appliance. This innovative new pilot information system will make total situational awareness feasible for the many general aviation cockpits that currently have no practical installation path for full size panel mounted large LCD systems. AVROTEC'S research program will advance human factors engineering technology and certification methods for cockpit displays, advanced input evices and the syn-thesis of visual and aural outputs. The system will be designed to optimize pilot performance using AGATE-developed integrated display formats for weather, navigation & terrain, traffic, systems status and ATC messaging. AVROTEC'S innovative system will enable the option of small, low cost, low-power displays in existing aircraft and in new airframe designs, greatly increasing safety and utility of small general aviation aircraft. The AVROTEC head-mounted pilot information system will also substantially reduce aircraft electrical power demand and instru-ment panel/cockpit cooling requirements compared to large, high-brightness, panel mounted LCD displays.
Potential Commercial Applications (Limit 200 words)
The market potential for AVROTEC'S head mounted system is excellent. Much of the existing general aviation fleet does not have sufficient panel space to install the more fully featured graphic map and control systems being devel-oped to run on PC type platforms. AVROTEC's "target" models of general aviation piston engine aircraft in the ex-isting fleet total more than 135,000 units or approximately 62.7% of that fleet. Also included in the potential are experimental (amateur built) aircraft, of which approximately 17-20,000 are flying, and helicopters. In addition, this product is ideally suited to a wide variety of non aviation mobile applications. The new AGATE aircraft will also provide a growing market for the system as a supplement to panel-mounted equipment

Pilot Voice Recognition for GA Aircraft
Technical Abstract (Limit 200 words)
The innovation proposed by Advanced Creations,
inc.(ACi) is to provide
a generic hands-free interface for general aviation
avionics systems.
ACi will analyze the impact of aircraft vibration,
ambient noise
levels, stress, G forces and atmospheric pressure
changes on the
accuracy of speech recognition algorithms,
developing the basis for an
innovative speech interface that will be low cost,
highly noise
immune, and capable of high level word command
recognition. The ACi
development will leverage the extensive speech
recognition research
funded by the banking community, Wright
Patterson AFB, and others,
coupled with advanced headphone/microphone
technology research being
performed by the cellular phone industry, and the
cockpit research
performed by the military. While tremendous
speech recognition
progress has been made, the existing research has
focused on rather
benign environments when compared to the cockpit.
Incorporation of
solutions for reducing the effects of ambient noise
through integrated
microphone/ headphones will be vital to program
success. We will
utilize the research results from various Air Force
and military
research programs via a Cooperative Research and
Development Agreement
already in place. The interface redundancy offered
by the proposed
system will ensure that performance and safety
levels in general
aviation cockpits increase significantly.
Potential Commercial Applications (Limit 200 words)
The achievement of the objectives of this proposed
SBIR program will
result in a readily exploited commercial product
with tremendous
market demand. An affordable generic hands off
interface will permit
the 21st century pilot to take full advantage of the
advanced avionics
systems being developed under the AGATE
program and others.
Achievement of the full potential of the AGATE
developments will
demand full utilization of the latest avionics systems
that permit the
pilot access to real-time weather and traffic data
and rapid
replanning capabilities. To fully utilize these
advances in a high
stress environment, a hands off pilot-system
interface will contribute
toward increased pilot performance and enhanced
safety.

Technical Abstract (Limit 200 words)
The propesed innovative Spray-Up Tooling System incorporates low-cost foam, resin and metallic-arc sprays in the fabrication of dimensionally accurate, durable, composite patterns, molds and assembly fixtures used for rapid prototyping and low-cost manufacturing of composite parts and assemblies. The proposed Spray-Up Tooling System integrates several existing technologies to produce precision tooling using labor with less than "master" skill levels. The STS tooling concept also uses integrated engineering, drafting, and anufacturing
computer tools for design and fabrication, resulting in increased accuracy and repeatability unattainable in hand-fabricated patterns, molds, and fixtures. A thorough investigation of materials and processes will result in the selection of primary candidates for specific testing. The then best-tested processes and materials will be down-selected at the end of Phase I for completion and demonstration of a complet Spray-Up Tooling System in Phase II effort. Successful development of the proposed STS will represent significant improvements in composite tool economy, reductions in prototype design and fabrication lead times, precision fit of composite assemblies, and lower overall life-cycle costs of composite tooling for General Aviation (GA) parts and assemblies.
Potential Commercial Applications (Limit 200 words)
Completion of the Spray-Up Tooling System will result in immediate incorporation into the certified production process of the Global GT-3 Trainer Airplane and the Global QCS Propeller. Global Aircraft Corporation (GAC) also plans to utilize STS in tool fabrication and rapid prototyping of composite parts for GA aircraft as well as other commercial applications. The STS and services provided by Global Aircraft will benefit smaller composite production companies who are seeking improved component quality and ower unit costs. A Spray-Up Tooling System will make composite technology advances more readily available and affordable to General Aviation manufacturers and consumers. The low-cost aspects of the Spray-Up Tooling System will facilitate success for the commercialization endeavor.

Automated Manufacturing System For
Grid Stiffened Structures For General
Aviation Aircraft
Technical Abstract (Limit 200 words)
In the 1980's, the General Aviation Industry went
into a tailspin due to liability issues. During the
subsequent hiatus in activity, several proof of
concept developments appeared. These concepts
have matured in the 1990's, under the impluse of
the Advanced General Aviation Transport
Experiments Program and others. As a result the
industry has renewed technical potential to
revitalize.
To date innovative lightweight/low cost, dolphin
shaped, composite airframes, which blend the wings
and the engines into the structure at their ideal
location, have been designed and test flown.
Superior strength/weight performance has been
obtained with structures which are Grid-Stiffened
along geodesic lines. Additionally many first time
observers are stunned by the amount of
unobstructed space available within the airframe.
What is currently lacking is an automated
manufacturing capability for grid stiffened
(geodesic) structures. This issue, if unresolved, will
keep the General Aviation Industry from
developing beyond the level of prototyping and
therefore revitalization would almost certainly be
out of the question.
W. Brandt Goldsworthy & Associates, Inc.
(WBG&AI) propose to solve this problem by
integrating current composites winding and
fiber-tow placement technology with blow-molding
technology to form a liner.
The results, which we need to obtain to consider
this program a success, is a turnkey composites
manufacturing cell which is capable of making a
dozen airframes per day. This challenge is so
profound that it will require entirely new ways of
thinking, and and it will likely have to include the
advantages of thermoplstics technology.
At the end of Phase I we expect to have developed
the concepts and designs necessary to automate
grid stiffened structures manufacturing.
Potential Commercial Applications (Limit 200 words)
The benefit, as described in the abstract, is that a
sorely needed manufacturing capability is created.
This will give rise to high technology and affordable
general aviation aircraft. There is also a significant
potencial to use this manufacturing technology for
producing components and tankage for the big
commercial airliners. As commercial space
initiatives continue to develop WBG&AI also
expects that payload shrouds and rocket tanks will
be made with the automated grid stiffened
manufacturing technology.

Project Title: Shared - Bandwidth Broadcast FIS System
Technical Abstract (Limit 200 words)
NavRadio proposes to develop a system which allows a single aviation VHF frequency to be shared by an existing audio broadcast signal and a VDL Mode 2 digital datalink broadcast system. This will allow addition of datalink broadcast capability to numerous existing facilities, without using any additional frequency spectrum or bandwidth, and without the need for coordination or assignment of new frequencies in potential conflict with existing services. The end result is enhanced effectiveness of the existing facility by adding digital dissemination, and enhanced VHF spectrum capacity by accomplishing FIS data broadcast without use of additional spectrum, thus reserving scarce spectrum for other interactive analog and digital services. The system is designed to be easily retrofitted to existing certificated facilities without change to any hardware or software, except for replacement of the in-lace VHF transmitter with a new one. The proposed product also includes all necessary data interfaces and processing to connect a variety of Flight nformation Services (FIS) data sources to the Shared Bandwidth transmitter, and manage the dual flow of voice and data automatically.
Potential Commercial Applications (Limit 200 words)
Upgrade of or initial installation with audio broadcast NAVAIDs such as automated weather systems (AWOS, ASOS, automated unicoms), voice advisory systems (ATIS), Remote Communication Outlets, or Automated Voice Altimeters (AVA) for addition of digital data broadcast. Potential customers include federal, state and local governments, airport authorities and operators, air carriers, and government and industry providers of Flight Information Services (FIS) worldwide. In addition, near-term deployment of a digital FIS broadcast capability, using the international VDL Mode 2 open standard, will fuel econdary commercial opportunities for a variety of end-user products such as airborne displays, receivers, and information services. Such a near-term deployment is facilitated by the lack of need for additional VHF frequency spectrum.

Technical Abstract (Limit 200 words) |
Recent advances during the last 2 years - in three key areas - have provided a foundation for an effective solution to this problem. The performance of computers continues to improve at an exponential rate allowing the migration of high-powered software tools onto one low-cost hardware platform. Likewise, as the storage price ($/meg) continues downward, increasing amounts of information are now being digitally developed and archived. Given these factors, the PC environment is now poised for significant use within GA product development. The Phase 1 effort involves the technical feasibility of transferring existing NASA funded research from a large aircraft application to GA. Phase II would then lead into the development of prototype software system, which fully integrates a Client/Serve Database system with ActiveX and OLE2 compliant software. Using this IDM technology will help generate tremendous savings to the life cycle cost of GA. |
Potential Commercial Applications (Limit 200 words) |
Continual improvements in product development, cost and performance are key for survival of most organizations. By its very nature, effective communication within a multi-disciplinary team will need to span organizational boundaries. An IDM tool would improve critical product development communication across the design, production and management roles. With widespread use, companies utilizing IDM technology will require a significantly larger number of licenses than would be typical of computer-aided design (CAD) tools. Therefore the market potential is larger than the current market for CAD products (+2 Billion 1996). |

A HIGH LIFT GENERATION AND
STALL/SPIN RECOVERY SYSTEM
Technical Abstract (Limit 200 words)
The proposal concerns a novel flight control
system, called "Delta Flaps" (Patent Pending) for
the generation of high lift and for stall/spin recovery
of General Aviation (GA) aircraft. The invention
addresses the need to reduce GA aircraft cost while
improving utility, performance and safety.
Compared to conventional high lift devices (HDLs)
such as flaps, the new invention requires much less
installed weight. It is simpler to integrate into the
wing design and can be deployed when the aircraft
is already in a stalled mode. The objective of the
proposed work is to generate a data base that
proves that the proposed high lift concept works
and can be used toward the development of a
generic design for the GA market. The Phase I
effort calls for flow visualization tests, for the
measurement of the polar of the model wings in a
wind tunnel, a first analysis of the aerodynamics of
the proposed HLD and flight tests of a radio
controlled airplane model with fully functional Delta
Flaps.
Potential Commercial Applications (Limit 200 words)
Delta Flaps serve as high lift generating device
during take-off and landing of aircraft, as lift
enhancing device for existing onventional flaps and
as stall/spin recovery device with either hand
operated or automatic deployment. They can be
used as either original or as retrofit system.

Low-Cost Piston Engine Health
Monitoring and Control System for
General Aviation
Technical Abstract (Limit 200 words)
The innovation proposed is a unique combination of
low cost sensors coupled with advanced adaptive
signal processing. The resulting system will
simultaneously provide vital engine diagnostics, and
advanced engine control. Sensors utilized in Phase
1 will include accelerometers and in-cylinder
pressure transducers. Event isolation will be
accomplished using active noise suppression
techniques. It is expected that by utilizing low-cost
multi-use sensors and on-board processing, the
diagnostic components of the system will more than
offset their costs due to a reduction in maintenance
requirements. Phase 1 will concentrate on
development and validation of an innovative
approach to diagnosing engine mechanical fault
conditions. The approach will be demonstrated on
two mechanical faults: excessive connecting rod
bearing wear and compression loss due to piston
ring wear. It is anticipated that the same approach
will be applicable to early detection of a number of
additional mechanical faults including piston skirt
slap, valve seating anomalies, maladjusted valve
train components, and preignition. The diagnostic
components of the production system would provide
failure prediction, thereby enhancing safety,
reducing scheduled maintenance costs, and
extending the required time between overhauls.
The control components will reduce emissions,
enhance performance and efficiency, extend enginelife, and enable
single lever control.
Potential Commercial Applications (Limit 200 words)
This engine monitoring and control system
developed for piston powered general aviation
engines has direct commercial potential in the
aviation market. While very few piston powered
general aviation airplanes have been manufactured
recently, there is a promising future for growth in
the market as existing airplanes disappear from the
market and there is great potential for retrofitting
the system to existing airplanes either before or
during engine overhaul. Also, the system or a
similar system could be used in much larger
numbers in automobiles, commercial diesel, marine,
and industrial motors. Finally, adaptations of the
system could be used on turbine engines, electric
motors, or any other rotating machinery.

Lightweight Aircraft Diesel Utilizing
Carbon-Carbon Technology
Technical Abstract (Limit 200 words)
DeltaHawk proposes to utilize carbon-carbon
technology in a lightweight 2-cycle diesel engine we
are developing for general aviation use. Our
engine's design represents substantial
improvements over the current fleet's engines:
lighter weight, smaller, fewer parts, lower BSFC,
smoother running, preferred fuel type, liquid
cooling, no electromagnetic interference,
single-lever power operation, and lower cost.
Carbon-carbon pistons and liners would provide our
engine with additional improvements in:
Efficiency -- Carbon-carbon components provide
the potential for increased thermodynamic
efficiency by reducing heat transfer from the
working gas through the liner, piston crown and
cylinder fireplate. Thermodynamic efficiency
translates in operation to improved fuel efficiency.
Pollution reduction -- Higher cylinder surface
temperatures promote more complete combustion
and shorter ignition delay, and therefore less
pollutants. This benefit would augment the
inherently lower pollution levels of the engine's
diesel (excess air) combustion cycle and use of
unleaded Jet-A fuel.
Weight reduction -- The higher strength and lower
density of the carbon-carbon material can reduce
engine weight by allowing lighter pistons and
smaller crankshaft counterweights.
Potential Commercial Applications (Limit 200 words)
Many dynamics are driving the general aviation
marketplace interest in diesel engines: the need to
migrate to a non-leaded fuel; the need to reduce
emissions; fuel availability, reduced flammability
and price advantages of diesel or Jet-A over
100LL; simplicity of operation; track record of
durability; and fuel economy. The DeltaHawk
diesel technical design will provide these benefits,
and has advantages over known diesel prototypes.
DeltaHawk is within six to eight months of
producing (in Experimental status) the first aviation
diesel in our business plan: the standard upright
V-4 200 hp model. Future development, phased

150-500 hp gasoline piston engines. Sales are
anticipated for new Experimental aircraft,

Project Title: Piezoelectric Ignition and Sensing Device
Technical Abstract (Limit 200 words)
The four stroke engine remains the main power source of light aircraft and motor vehicles. Constant efforts concentrate on improving the efficiency and reducing harmful emissions from engines. A Piezoelectric Ignition and Sensing Device has been formulated that will improve efficiency and reduce harmful emissions of four stroke engines. Approximately ten percent of the electrical power produced by an internal combustion engine is used for ignition. By removing the ignition power requirements, a smaller alternator can be used and overall system efficiency will be improved. Internal combustion engines still have significant environmental harmful emissions. These harmful emissions mostly occur when the engine is running with misfiring, knock and mistiming. To date, the sensing of these conditions rely on secondary sensing. Using the piezoelectric element as a pressure sensor will give a direct indication of the presence of knock, misfiring and mistiming.
Potential Commercial Applications (Limit 200 words)
All the manufacturers of engines, light aircraft and automotive, will welcome any improvement on current engines. Federal regulation requires new generation engines to be more fuel efficient and environmental friendly.

Project Title:
An advanced system for dynamic model
deformation and angle-of-attack
measurements
Technical Abstract (Limit 200 words)
The development of a commercially viable model
deformation and angle-of-attack measurement
system is proposed. The system will have a
real-time dynamic measurement capability of at
least 60 Hz, and an accuracy of 0.005 degrees or
better. The Phase I effort focuses on performing a
thorough optimization study and selecting an
appropriate implementation, along with the
demonstration of a prototype system. A follow-on
Phase II effort would result in a ruggedized
commercial version for operation in major NASA
wind-tunnel facilities. The significance of such a
system is that it has the potential to replace the
conventional accelerometer-based angle-of-attack
system under difficult dynamic load conditions. In
addition, it can shorten the wind-tunnel testing
process by providing accurate wind-on model
deformation information for the proper
interpretation of loads data. The approach is
innovative in its combination of the convenient
single-camera photogrammetric approach with
modern digital video systems and a new real-time
target-tracking process. By providing an accurate,
easy-to-use, non-contact measurement of several
very important model parameters, the system will
reduce wind-tunnel testing cycle time and improve
the value of performance data.
Potential Commercial Applications (Limit 200 words)
Current video-based photogrammetry systems in
use at NASA wind tunnels are still in the
development stage, and the importance of these
systems is widely recognized. In the area of
angle-of-attack measurements, there is a clear
need for an optical method to replace the current
accelerometer-based system under dynamic
conditions. Commercial active-target systems have
already been used in some NASA facilities, showing
that a market clearly exists for these systems.
Since it is built with off-the-shelf technology, the
proposed system has the potential to provide
optical angle of attack at a substantially reduced
cost compared to existing systems. In addition to
wind-tunnel applications, there is a huge market for
remote optical measurements in many other areas.
Machine vision systems are now routinely used in
factory environments for quality inspection and
process control. Other industrial applications
include architectural and terrestrial surveying, and
forensic reconstruction. In the medical field, the list
of potential applications includes the diagnosis of
muscular and skeletal problems, studies of
anatomy, and reconstructive surgery. Many of
these applications could benefit from the dynamic
capabilities of our proposed system.

Project Title:
Fiber Bragg Grating Sensors for
Simultaneous Measurement of Shear
Force, Strain, and Temperature for
Aerospace Applications
Technical Abstract (Limit 200 words)
SEACOM proposes to develop new fiber Bragg
grating (FBG) sensors for wind tunnel
instrumentation to measure shear force, strain, and
temperature simultaneously. Innovations include:
· a pair of cross-tilted FBG's subjected to shear
force producing Bragg wavelength shifts in opposite
directions while producing strain and thermally
induced shifts in the same direction. A differential
measurement of Bragg shifts gives a measure of
the shear force independent of strain and
temperature. Currently such an instrument is not
commercially available;
· a dual wavelength method using co-written Bragg
gratings to measure strain and temperature
simultaneously during structural deformation of
wind tunnel models.
The Phase I research objective is to verify the
proposed concepts by conducting experiments on
FBG's subjected to fluid flow, mechanical strain and
thermal stress. In the Phase II research, sensors
will be developed that are capable of distributed or
multi-point measurement to provide more data per
tunnel-occupancy-hour. The all-optical nature of
FBG sensors makes them suitable for remote
operation and for measurement in a severe
environment of electromagnetic interference or
vibration. The proposed FBG sensors will be useful
to NASA for both cryogenic and high temperature
testing of wind tunnel models.
Potential Commercial Applications (Limit 200 words)
Commercial Applications:
- Remote and distributed flow measurement in an
explosive environment such as oil and gas pipes
- Water flow measurement in hydroelectric power
generation
- Industrial processes requiring flow and
temperature measurements
- Shear force measurements in the design of
hydrofoils
- Health monitoring of structures such as bridges
and buildings

Project Title:
Vibrostatic Buffeting Alleviation
Technical Abstract (Limit 200 words)
NASA Langley Aeroelasticity Branch is addressing
aircraft lifecycle costs by actively reducing the
vertical tail buffeting due to vortices originating at
wing/fuselage leading edge extensions ("LEX")
during short duration high-alpha maneuvers. In a
departure from previous methods, the system uses
an piezoelectic induced strain actuation ("ISA")
mechanism. As applied to the 1/6 scale F/A-18
Transonic Dynamic Tunnel ("TDT") model, the
port vertical tail is equipped with piezoceramic
elements that enables alleviation of buffet loads
through active means. However, the current system
appears to a number of deficiencies. Although
piezowafers are lightweight and easily
attachable/embeddable the present system requires
bulky electronics and undue control power and
complexity to achieve necessary bandwidth and
stroke requirements. The system provides no level
of passive damping on the vertical tail either in high
strain flight condition or in normal flight. Moreover,
there is insufficient actuator authority to affect
modes other than the fundamental root bending
moment. EMF proposes a new concept of
vibrostatic damping and d33 bimorphs that
increases the control authority, minimizes the drive
electronics requirements and substantially reduces
power consumption while simultaneously
introducing a measure of passive damping at both
low and high alpha regimes.
Potential Commercial Applications (Limit 200 words)
EMF's vibrostatic damping concept creates a new
product for a multifaceted commercial marketplace.
The proposed system has application to almost any
intermittent damping vibratory systems positioning
or attenuation incorporating piezoelectric or
electrostrictive devices. Opportunities include:
Ground and Space-borne Optics, Ultrasonic
Cleaners and Sports & Leisure Equipment.
Exploitation of the size and power reduction in
active mode combined with added passive damping
achieved under this project would make the
technology viable for a wide variety of such
applications. As noted in the support letter, EMF is
developing strategic partnerships for commercial
applications of this technology with Boeing Long
Beach. In particular, significant interest exists for
its application to wing flutter for the HSCT. EMF is
further developing strategic partnerships with
Blatek Corporation and Quiet Power Industries for
direct commercial applications of the outcome of
this research.

CFD/CSD Interfacing via an
Innovative Structural Boundary
Element Method
Technical Abstract (Limit 200 words)
An innovative structural Boundary Element
Method (BEM) Solver is developed for interfacing
the Computational Fluid Dynamics (CFD) and
Computational Structural Dynamics (CSD) grids.
Formulated as a solid mechanics problem with a
minimum strain energy requirement, the BEM
Solver generates a truly three dimensional (3-D)
Universal Spline Matrix. The Universal Spline
Matrix is a vector operator which includes the
coupling of displacements and forces along all axes.
Based on a similar formulation, an Exterior BEM
Solver is also developed to account for the flow grid
deformation. Thus the BEM Solver allows a unified
treatment of the displacement and force
transformation for CFD/CSD interfacing as well as
the computation of the flow field grid deformation.
The solution procedure is fully automated and
requires no further user interaction, therefore it is
ideally suitable for Computational Aeroelasticity
(CAE) and Multidisciplinary Optimization (MDO)
applications.
Potential Commercial Applications (Limit 200 words)
Considerable growing interest is being generated in
new methodologies for aircraft aeroelasticity and
rotorcraft/STOVL aircraft CFD/CSD and
computational aeroelasticity (CAA) interactions
requiring high-level, high-resolution CFD solutions
through CFD/FEM grid interfacing. The BEM
Solver can meet this requirement to provide
accurate and effective data transferal in high
fidelity between grid systems, thus improving
solution accuracy in aeroelastic predictions in
problems such as limit cycle oscillation and flutter.
The commercialized BEM Solver will act as a data
transferal modem requiring minimum user learning
time. Meanwhile, ZONA's reputation and track
record in supporting the aerospace industry with the
ZONA codes for aeroelastic applications will assure
the success of the future commercialization of the
BEM Solver.

Dynamic Stall Control on Rotorcraft
Technical Abstract (Limit 200 words)
A program for the development of an active control
system for controlling dynamic stall on rotorcraft
blades is proposed. The system utilizes an array of
pulsed jet actuators near the blade leading edge to
control unsteady lift and flow separation during
transient pitch-up. The control system will be
developed and tested on a rotor blade section
mounted in a low-speed subsonic wind tunnel at
Physical Sciences Inc. The ability to control and
delay dynamic stall events during oscillatory
pitching of the model will be evaluated in open-loop
experiments. Results from the open-loop tests will
be used to develop a state-space model to describe
the unsteady aerodynamic loads both with and
without control. Using the model, control algorithms
will be tested in software using MATLAB/Simulink.
The active controller will be implemented on a
high-speed digital signal processor and evaluated
on-line in its ability to suppress dynamic stall. The
experimental results will be used as guidelines for
the design of a Phase II prototype control system
for large-scale testing at flight conditions.
Potential Commercial Applications (Limit 200 words)
The performance of both commercial and military
rotorcraft may be enhanced through the application
of the proposed control system. The system will
alleviate problems which currently limit high-speed
forward flight and which produce excessive noise
and vibration in certain flight regimes. The
successful development and application of this
control system will result in the design of more
versatile and quiet rotorcraft and VSTOL vehicles.

A First-Principles Based High Order
Discontinuous Galerkin Methodology
for Rotorcraft Flowfield Studies
Technical Abstract (Limit 200 words)
A first-principles based high order Discontinuous
Galerkin (DG) methodology for rotorcraft flow field
studies is proposed. A 3rd/5th spatial order compact
DG methodology will be developed. The scheme
developed will be compact, i.e., the cell update
overtime depends only on the information from the
cell and its immediate neighbors. A unique
advantage of the compactness of this method is that
it does not require any special treatment near
boundaries and Chimera intergrid boundaries to
maintain high order accuracy.
The compact DG scheme will be implemented in
conjunction with an innovative selective overset
refinement method. This will ensure that the
rotor-blade tip vortices convect over large
distances without dissipation. Thus, this
methodology strives to achieve the philosophy of
h-p refinement for optimal computational efficiency
in the most practical manner. The compact high
order DG/selective overset refinement will be
implemented in an ENO-based high order 3D,
unsteady, overset NS solver specifically developed
for rotorcraft studies by the Principal Investigator
and the Consultant at Georgia Tech during the
demonstration phase.
The proposed methodology will be validated and
tip-vortex core velocity profiles will be compared
with experiments for a rotor in hover. The
comparative costs (CPU, memory overhead),
robustness of the proposed high order compact DG
method with conventional wide-stencil ENO,
MUSCL schemes will be analyzed. Information
fidelity during intergrid flow-feature transfers in
overset grids will be examined.
In Phase II, the focus will be on porting this
methodology to standard NASA platforms such as
OVERFLOW, and their application to handle
complex issues such as rotor-blade interactional
noise issues, generic rotor craft interactional
problems, and tip shape acoustic characteristics
predictions.
Potential Commercial Applications (Limit 200 words)
The proposed first-principles based efficient
resolution of vorticity-laden flowfield will be
applicable to diverse application such as non-linear
lift systems, high lift systems, and vortex buffeting
in fighter planes. Commercial application to civil
aviations include studies of wing-trailing vortex
dynamics from large aircrafts such as 747's, and
prediction of the life-span of such vortices.

Reduced Order Free Wake Modeling
for Near Real Time Simulation of
Rotorcraft Flight Mechanics
Technical Abstract (Limit 200 words)
Rapid, realistic simulation of rotorcraft flight
mechanics is a continuing challenge for the
mission/flight simulation community, aircraft
designers, and control system specialists.
Accelerating flight dynamics models while
integrating them with state-of-the art performance
analysis tools is a particularly promising way to
streamline the design, testing, and certification of
new rotorcraft, particularly novel civil tiltrotors.
Efficient modeling of complex
wake/fuselage/empennage aerodynamic
interactions lies at the heart of this problem, though
rapidly evolving computational methods are now
bringing advanced aerodynamic modeling
techniques within reach for these applications. The
thrust of this proposed effort is to address the
limitations of current flight dynamics modeling tools
by developing dramatically accelerated, reduced
order embodiments of validated free wake models.
This will provide high fidelity treatments of
rotor/wake and rotor/body interaction for flight
mechanics and simulation activities while yielding
near real time performance on modern
workstations. This new model will also address
current limitations in predicting helicopter and
tiltrotor response to control inputs for general flight
conditions and will also incorporate
body/empennage effects. While integrating
smoothly with established performance analysis
tools and possessing strong "stand-alone"
capabilities, the model will be designed to be
operable with a variety of existing flight dynamics
codes for maximum utility.
Potential Commercial Applications (Limit 200 words)
Development of this capability would address the
need for new insight into the flight mechanics of
civil tiltrotor designs or other novel dual-rotor
configurations. It would also improve the fidelity of
fixed and moving-base helicopter flight simulators,
as well as aid the development of advanced flight
controls. In addition, better understanding of
helicopter and tiltrotor flow fields could also aid
commercial operators concerned with safe
operating procedures around ground obstructions or
in unusual attitudes or operating conditions caused
by environmental conditions or noise abatement
requirements.

Control and Alteration of Wing-Tip
Flowfield for Induced Drag Reduction
Technical Abstract (Limit 200 words)
The ability to alter positively the wing-tip flowfield
is a dominant factor for reducing drag-due-to-lift
and improving the aerodynamic efficiency of civil
transports. The induced drag problem exists due to
the finite span of the wing and consequently, the
formation of a tip vortex. A novel technique for
reducing induced drag is proposed. This research
focuses on effective control of the wing-tip vortex
through modifications of the tip geometry, thereby
altering the vortex initiation flowfield and
reducing the intensity of the shear-layer roll-up
process. The technique is innovative because of its
simplicity. The effort focuses on the control of
vortex-induced drag for moderate to high aspect
ratio wings and simulation of the modified tip-vortex
flowfield. The reduction in fuel burn associated with
enhanced aerodynamic performance will help
NASA meet its goal of environmental compatibility
(emissions).
Potential Commercial Applications (Limit 200 words)
Design of fuel efficient wings for commercial and
military aircraft, better design of rotor blades to

Space-Time Conservation Element
Solution Element Method for Pulse
Detonation Engine
Technical Abstract (Limit 200 words)
We propose to develop a computer code for
simulating Pulse Detonation Engines (PDEs). This
code will be based on the space-time conservation
element-solution element method. The basic idea of
this method is global and local flux conservation in
a space-time domain. In this method conservation
variables and their derivatives are treated as
unknowns which are defined on the solution
element. A time marching scheme is constructed
using local conservation within each conservation
element. It has been demonstrated by that this
method yields high resolution for shocks,
rarefaction waves, acoustic waves, vortices,
detonation waves, and shock/acoustic,
shock/vortices interactions.
During Phase I of this project, we propose to
develop robust computer codes, based on the above
methodology, for unsteady, implicit one dimensional
and quasi one dimensional PDE problems, with
multistep chemistry. These codes will be extended
to solve general combustion problems, validated
with benchmark problems and compared with
MOZART code.
At the end of Phase II, PDE and combustion
software packages will be available for
axisymmetric and three dimensional geometries
using structured and unstructured grids with full
multistep chemistry.
Potential Commercial Applications (Limit 200 words)
The analytical formulations and their numerical
implementations proposed in this research will
enhance the capability in numerical simulation of
combustion problems and computational fluid
dynamics in general. The computer codes for
deflagration and detonation reactions developed in
the Phase I and Phase II of the proposed
developments, will result in significant performance
improvement in analysis of a wide range of engine
systems. Moreover, they can be utilized to perform
numerical experiments in the design phase, instead
of building expensive prototypes over and over

both in the United States and abroad.

Project Title: Automatic Optimization of Engine Component Design Through Neural Networks and Genetic Algorithms
Technical Abstract (Limit 200 words)
The proposed work aims to automate the optimization of aeroengine components through the application of Artificial Intelligence (AI) techniques to state-of-the-art component design tools. The design of aeroengine components is a complex process requiring many steps and hundreds of minute design decisions in an iterative process. These steps range from meanline (or 1D) design through 3D viscous flow calculations (CFD) and finite element structural analysis (FEA). In the proposed work, AI will be employed to optimize the turbomachinery design process and reduce, to the degree possible, repetitive actions required by the
designer. Both neural networks and genetic algorithms will be implemented in a commercially accepted meanline design program, which is part of a complete design system for gas turbine engine components. AI will be used to create and optimize designs which will be compared to designs created and optimized manually. While initial work will be for meanline design, this work will form the foundation for adding AI to other steps in the overall component design process in Phase II. If properly applied and tested, this technology has the potential to revolutionize the design process for turbomachinery, resulting in the ability to achieve superior performance within a reduced design cycle time.
Potential Commercial Applications (Limit 200 words)
Commercialization for this technology will be very straightforward. The proposer is an established publisher of design software tools for the turbomachinery industry, with users such as Pratt&Whitney, General Electric, Allied Signal, Nuovo Pignone, General Motors, Ingersoll-Rand, Dresser-Rand, Solar Turbines, Honda, and MHI. This AI technology will first be commercialized through integration into an existing commercial meanline design program. Later work will extend it to other parts of the complete design system.. The strong client base which the proposer enjoys can be expected to warmly embrace these improvements.

Project Title Reliability-based Optimization
for Aircraft Structural Design
Technical Abstract
This proposal describes a six month study to demonstrate the feasibility of applying a
recently formulated algorithm for reliability-based optimization (RBO) to the structural
design of advanced aircraft. The goal of the project is to develop a computationally
efficient RBO capability for practical applications involving large numbers of design
variables and constraints. The new algorithm will be integrated with an existing commercial
structural design optimization code, ASTROS, originally developed for the Air Force Wright
Laboratory. Commercialization and maintenance of the code have been taken over by Universal
Analytics Inc. (UAI) under a Cooperative Research and Development Agreement (CRDA) with
Wright Laboratory. ACTA is teamed with UAI as a
subcontractor on this project.
Application of RBO requires the quantification of modeling uncertainty. A second innovation
is proposed to derive modeling uncertainty statistics from readily available dynamic and
static analysis and test data. Dynamic mode shapes and frequencies have previously been
used to generate databases of structural modeling
uncertainty for spacecraft and automobiles. The same will be
done for aircraft under the proposed contract. In addition, static
analysis and test data will be collected and processed to create
a historical database of structural modeling uncertainty for aircraft.
Potential Commercial Applications
Structural design of commercial and military aircraft.
Structural design of space structures.
Structural design of automotive structures.
Structural design of advanced structures in general.

Reliability-Based Multi-Disciplinary
Optimization of Large Multi-Component
Systems Using Interdigitation
Technical Abstract (Limit 200 words)
The proposed research will develop a new
formulation that makes multi-component
reliability-based optimization (RMDO) problems
only slightly more computationally intensive than
conventional MDO problems. ARA and Northrop
Grumman will team with Engineous Software to
build on Engineous' commercially successful
optimization approach that couples methods
(interdigitation) and develop an algorithm that
explicitly treats uncertainties during the design
optimization. Key to success of this approach is the
use of innovative analysis strategies. Without such
strategies RMDO will be prohibitively expensive.
First, we will use the concept of results sharing
wherein we use the reliability-based analysis results
in the design space search process. Because
solution of the probabilistic analysis problem can be
formulated as a sub-optimization problem, gradient
computations in the random variable space can be
used by the optimizer. Second, we will employ the
Engineous rule-based system to limit probabilistic
analysis to a working set of constraints and random
variables. Third, we will use efficient direct
differentiation and successive approximation
techniques. RMDO obviates the need to do costly
sensitivity analyses after the optimum is found
since uncertainties and variabilities are accounted
for during optimization and RMDO results in a
robust solution since the range of operating
conditions is considered during optimization.
Potential Commercial Applications (Limit 200 words)
The recent strong demand for reliability-based
design methods in the aerospace, automotive, and
civil infrastructure industries provides a strong
market for optimum design methods that can work
within the reliability-based framework. No
commercial RBO tools exist. By working with a
commercially successful MDO package, the
chances of commercial success are quite high.

The proposed effort is concerned with the

The software is innovative for several reasons.
First, it would be the first methodology capable of
handling both measures of product performance and
reliability. Second, it would enable the consideration
of variable uncertainty in the analysis of the
product design. The incorporation of variable
uncertainty would enable the designer to determine
the impact such uncertainty plays in the desired
product performance and reliability. The software
would directly estimate the sensitivity of each
performance measure to each random variable, as
well as the performance sensitivities to random
variable uncertainties. The ability to consider
variable uncertainty in a multi-disciplinary
optimization routine would be unique, and would
represent a significant advance over existing design
software.
Potential Commercial Applications (Limit 200 words)
The proposed software program would permit
multi-disciplinary evaluation of product designs and
include both variable uncertainties, measures of
product performance, and reliability. This software
capability would dramatically improve the
performance and reliability of aviation, aerospace,
and other large complex systems. The capability of
assessing a product design under consideration of
multiple performance measures and reliability is a
significant improvement of existing methods.
Application of the software would be found in any
complex product or component where engineering
expertise has been used to determine the
appropriate trade-off in design and performance.

Project Title: Software Modules in Structural Control Laws, Optimizer and Solid Modeler.
Technical Abstract (Limit 200 words)
Integration of individual aircraft subsystems (aerodynamics, structure, propulsion, control, ...) made possible by increased computing capabilities, has potential of improving performance and safety of the aircraft if considered early in the design phase. Integration, however, makes the system model much more complex and opens new issues not dealt with before. To be able to design and verify such a complex system, it is crucial to have efficient software tools or simulation, analysis and prediction of their behavior under the simultaneous influence of the subsystems. The goal of this project is to define and build the environment for development and verification of new control laws, and for the comparison of new and existing control methodologies relevant to the aerospace industry. Also, the goal of the project is the development of a solid modeler and a structure optimizer routines and their integration with controllaws design module as well as with existing general purpose codes. The environment will consist of the tools for design, simulation, and analysis of various linear and nonlinear control theories. For this purpose the commercially available design tools Matlab and NASA software packages (STARS) will be used asa powerful combination for control laws development and verification. All necessary interface code between various tools will be developed to make whole environment user friendly. Finally, the testbed will be designed and constructed with the aerospace application in mind, but would also be kept general enough to be attractive for commercial utilization.
Potential Commercial Applications (Limit 200 words)
Computer-aided design and analysis software package will be developed for the design, analysis and verification of control laws for complex multivariable systems. Also, a solid modeler and an optimizer will be developed which together with control law design will yield an effective multidisciplinary aerospace vehicle design tools. This environment will be very attractive for commercial utilization as an invaluable tool for research and practicing engineers in industry.

Project Title: Balloon Launch Return Vehicle (BLRV)
Technical Abstract (Limit 200 words)
This proposal describes an innovative low cost approach to launch small payloads into space and return them to a selected location on Earth. The innovation to be developed will be an analytical model of a rocket powered aerodynamic lifting body or aerospace plane lofted by a high altitude weather balloon to over 80,000 ft. for a ballistic launch into space (over 50 nautical miles) which then glides back with payloads to a designated site.
Potential Commercial Applications (Limit 200 words)
This extremely low cost approach to carrying payloads and instrumentation to space and returning them safely to Earth is expected to receive wide application by customers such as NASA, military services, National Weather Service, Universities and news/weather networks if it can be proven that safety concerns can be successfully resolved. Typical applications are gathering of data for general weather prediction and environmental studies. It is expected that the BLRV approach to space flight will be adopted as a low cost test method for vehicle propulsion system and aerodynamics evaluations.

Resolving Turbulence-Chemistry
Interactions in Supersonic Combustion
Technical Abstract (Limit 200 words)
Beam Technologies will develop a hybrid
finite-volume/Probability
DensityFunction (PDF) code which will significantly
enhance the
ability ofNASA/Langley and industry to study
supersonic combustion
problems. Current finite-volume CFD codes used
for supersonic
combustion (e.g., NSAS's LARCK code) take no
account of the
turbulence-chemistry interactions, which can have
an
order-of-maganitude effect on the mean reaction
rates. PDF
methods are known for their ability to treat the
nonlinear chemical
reaction terms without modeling, thus resolving the
principal
turbulence-chemistry interactions. For this reason,
PDF methods are
becoming the approach of choice in, for example,
the gas-turbine and
chemical processing industries. The proposed
project will extend the
PDF's ability to handle supersonic reacting flows
and integrate the
PDF code with the LARCK code for efficient
simulations. The finished
code will also allow users to choose between
several modules which
will provide both the LARCK code's efficienty in
simulating the
turbulent velocity field and the PDF code's
accuracy in predicting the
thermochemistry. The proposed work directly
supports NASA objectives
in hypersonic and SCRAMJET design.
Potential Commercial Applications (Limit 200 words)
Beam's proposed code will provide significant
improvement for
predicting high-speed reacting flows with complex
chemistry. The code
will make a significant contribution to the
hypersonic industry: it
will be an important step towards the reliable
computer based design
of SCRAMJETS.
The PDF modules developed will be suitable for
connection with other
finite-volume codes.In other applications, the
proposed work will
allow the chemical and power industries to evaluate
the performance of
their products before any prototype or pilot plant is
built. This will
not only significantly reduce their capital
investment but also
provide more flexibility to the design and
modification processes.
These advantagesassure a large commercial
market and potential for
other turbulent reacting flow applications.

Microfabricated, Low Maintenance Skin
Friction Sensor for Highly Transient
Applications
Technical Abstract (Limit 200 words)
Although skin friction measurements have been
made in highly transient facilities in the past,
accurate measurement of wall shear stress with
adequate spatial and temporal resolution has been
difficult to perform due to the physical size of the
instrumentation and due to high maintenance
requirements. Earlier designs required oil to fill the
interior of the gage, but by utilizing new
microfabrication techniques, such as stereo
lithography, new design possibilities will allow skin
friction sensors without the oil and its intendant
high maintenance and care but with higher spatial
and temporal resolution.
This instrumentation is crucial to the development
and operation of affordable, safe, and efficient 21st
century aircraft and other high-speed transportation
systems. The accurate measurement of wall shear
stress in fluid dynamic devices is important for
understanding the basic fluid physics involved and
assessing the performance of the device, leading to
improvements in the design and operation of future
high-speed transportation systems.
An excellent development team has been
assembled including Professor Joseph Schetz of
Virginia Tech, a world leader in wall shear stress
measurements, and F&S, a leader in sensor
development and commercialization. The F&S team
is both qualified and motivated to build upon their
combined demonstrated capabilities.
Potential Commercial Applications (Limit 200 words)
The materials and technology now exist to construct
a microfabricated sensor for the accurate
measurement of skin friction in highly transient
wind tunnels. This instrumentation is crucial to the
development and operation of affordable, safe and
efficient 21st century aircraft and other high-speed
transportation systems. The accurate measurement
of wall shear stress in fluid dynamic devices is
important for understanding the basic fluid physics
involved and assessing the performance of the
device, leading to improvements in the design and
operation of future high-speed transportation
systems.
In addition, research in the wide temperature range
instrumentation area will provide transducers with
commercial uses that will include transportation
system design, development and operation,
semiconductor fabrication, commercial jet engines,
automobile engines, the metal, ceramic and wood
processing industries, and the power generation and
monitoring systems for coal-fired, nuclear and
fuel-cell technologies. F&S has identified many end
users of the microfabricated wall shear stress
sensor within the government such as Air Force,
NASA, NASP, ARPA, Army, Navy, and the DOE.

Concept Map-Directed Hyperlinking for
Collaborative Design
Technical Abstract (Limit 200 words)
NASA, which depends on the services of many
diverse units to accomplish its missions, is
challenged by a multiplicity of information and the
geographical distribution of its personnel working
towards a common goal. This Phase I effort
proposes a novel technology developed within a
cognitive framework to fulfill the collaborative
design and information sharing needs of NASA
multi-operator teams. Our initial effort is focused
on geographically distributed operators who
generate information products and deploy these
products to a central server. Our Concept
Map-Directed Hyperlinking for Collaborative
Design has three development phases: 1)
identifying the relationships and dependencies
among pieces of information needed and generated
by operators via knowledge elicitation; 2) using the
results from the knowledge elicitation to construct a
concept map to blueprint the cognitive processes of
a multi-operator team; and 3) developing a
server-side software agent to generate hyperlinks,
directed by the concept map, between similar and
related information. Our approach is unique in that
it automatically generates meaningful hyperlinks
among information residing on the server, therefore
facilitating information sharing in a way that
corresponds naturally to the team cognitive
process.
Potential Commercial Applications (Limit 200 words)
The technology developed under the Phase I effort
has several potential commercial applications.
Market areas that can be targeted include the
Internet, corporate intranets, and other large
networks. Specific applications include: 1)
automatic hyperlinking capability for
Internet/intranet-based research groups; 2)
corporate data sharing through hyperlinking; 3)
intelligent-agent directed hyperlinking; and 4)
prevention of dangling hyperlinks.

Intelligent Solution Optimization Using
Artificial Neural Networks Applied to
Numerical Flow Solvers
Technical Abstract (Limit 200 words)
General purpose flow solvers are designed to treat
a wide class of fluid flow problems. Simulation of
any one particular class of problems is therefore
rarely optimized. Moreover, many algorithms
require frequent user monitoring and adjustment of
code parameters to ensure a successful run. A need
therefore exists to automatize code execution, with
concomitant run-time, problem dependent
optimization of the computational effort. Artificial
Neural Network (ANN) approach offers a natural
solution to this problem of "intelligent" algorithm
control. The networks inherent nonlinearity and
trainability allows the development of algorithm
control and optimization software capable of
self-tuning to any problem at hand. ANN-based
code optimization will be applied on two levels. High
level control will automatically determine the best
combinations of code parameters that determine
the most optimal overall simulation convergence
rates. Low level control will optimize performance
of individual computational modules. This project is
of direct benefit to NASA, as the work will result in
a new computational paradigm capable of radically
decreasing design cycles which rely on interaction
between simulations and hardware development.
Potential Commercial Applications (Limit 200 words)
Commercial potential for the developed software is
very high as it will allow, for the first time,
non-experts to use high fidelity CFD simulators. It
will also be of great interest to engineers who
routinely use flow simulators for hardware design,
as the software would significantly reduce
simulation times and increase throughput.

Coordination Tool for Large, Complex
Aerospace Designs Using Artificial
Intelligence (AI) Techniques
Technical Abstract (Limit 200 words)
The overall goal of this project is to reduce design
errors and design time of aircraft by developing an
Aerospace Design Coordination Tool (ADCT),
which would coordinate a distributed team of
engineers. It will track design decisions, save
decision rationale, recognize conflicts and aid their
resolution, monitor design changes, and coordinate
the design change and updating process - a leading
source of errors in distributed aerospace design
teams. ADCT will use several concepts from AI
which have been combined into a system, called
Redux, of theories, capabilities, concepts, and
formalisms, explicitly to aid the management and
coordination of complex designs and design
changes. The ADCT would be interfaced to current
Aerospace design tools and be useable over several
different kinds of networks, to coordinate a large,
distributed team of engineers. We will prove its
feasibility by developing and demonstrating a
proof-of-concept, limited prototype.
SHAI has complemented our extensive AI R&D
expertise in the field of collaborative design with
Ken Price, a member of Boeing's Aerospace design
team who participated in all phases of the design of
Boeing's 777 and supplies familiarity and
experience with the Aerospace design process and
with design tools used.
Potential Commercial Applications (Limit 200 words)
The primary benefit of this project will be the
dramatic reduction of errors and design time and
the increased quality of designs for complex
aerospace systems. The Aerospace Design
Coordination Tool (ADCT) will facilitate the
management and coordination of complex
aerospace designs and the associated engineers
who are often geographically distributed and in
separate organizations. Use of a Boeing design
engineer facilitates commercialization.

Project Title: Evidential Reasoning Tools For Risk Management in CFD
Technical Abstract (Limit 200 words)
CFD managers are continually confronted with the task of deciding how to achieve project objectives within time, budget, computational, and manpower constraints. In addition, CFD engineers that run analyses are also continually confronted with the task of deciding such things as what flow features to model, how to parameterize and construct grids, what code to use, and so forth. All real-world decisions must be based on varying degrees of uncertain information, and consequently with some degree of risk. Currently, the process of assessing project risks is adhoc, largely experiential, and highly manual in nature. Even automated tools to dynamically assess the fidelity of flow calculations and to predict the risks of continuing or altering flow calculations are lacking. The proposed innovation involves using probabilistic and fuzzy logic methods as the foundation of automated tools and computer-based applications that are designed to help users manage uncertainty and to assess the risks associated with CFD-related tasks. Having such tools is expected to help CFD users and managers identify and address those aspects of tasks that have the greatest potential to negatively impact CFD activities and to consequently take appropriate actions to mediate undesirable events.
Potential Commercial Applications (Limit 200 words)
The need for decision tools within the CFD community is significant. Having a structured and formal way to identify areas and aspects of a task that might have the greatest impact on the quality of CFD products or the overall success of a project is expected to generate a large market for such capabilities throughout the private, government, and academic sectors. With such capabilities, problems can be addressed earlier rather than sooner, thus reducing cost, time, and wasted resources.

An Innovative Aerodynamic Engine for
the Next Generation Design System
Technical Abstract (Limit 200 words)
The key to maintaining the United States' lead in
the commercial and military aircraft markets lies in
the reduction of design cycle times. A shorter
design cycle means lower development costs, more
rapid market response, the potential for multi-point
design optimization, and the opportunity to
incorporate future high risk technologies into new
designs. Continuum Dynamics, Inc. proposes the
development of a new "aerodynamic engine" for
this next generation design system. The central
innovations in this approach are: a fast panel
methodology providing order of magnitude
reductions in both computation time and storage
requirements over existing panel methods; a
modular fast kernel which may be integrated
directly into existing panel codes, providing aircraft
manufacturers tremendously improved performance
while maintaining their existing knowledge and
design bases; and the integration of a free vortex
particle formulation into this fast panel
methodology, providing designers with an efficient
tool for modeling vortical wake and separation
phenomena. The development and integration of
these key concepts will both lead to a major
reduction in design cycle times and provide
designers with an expanded envelope modeling tool
to understand and potentially exploit unsteady,
vortical flow structures in future aircraft designs.
Potential Commercial Applications (Limit 200 words)
The ability to rapidly calculate both inviscid and
viscous/vortex-dominated flows about complex
bodies over an entire flight operating range,
constitutes a powerful new tool for assessing
performance, loads, and flow characteristics of new
and existing configurations. The technological
innovations to be developed and implemented here
will power a family of new aerodynamic design
products including: (1) a fast-panel kernel which will
be marketed directly to aircraft manufacturers and
to panel code developers for incorporation into
existing panel based design systems to yield an
order of magnitude reduction in both computation
and storage requirements; (2) a new "aerodynamic
engine" with the potential of revolutionizing the
aircraft design process, by enhancing the flow
modeling fidelity in the preliminary stages of
design; and (3) with the integration of emerging
solid modeling and optimization technologies, a
completely new preliminary design system with the
power to perform multi-point design optimization
and rapidly evaluate high risk technologies.

High Density Energy Storage System
Based on an Extremely Lightweight
Proton Exchange Membrane Fuel
Cell/Electrolyzer Set
Technical Abstract (Limit 200 words)
High Altitude Long Endurance (HALE) aircraft,
especially unmanned aerial vehicles (UAVs) offer a
unique combination of capabilities for use as
observation platforms and relay links. They operate
closer to the ground and at lower cost than
satellites, while being capable of staying over a
small area for extended periods and remaining aloft
virtually indefinitely. Staying aloft indefinitely
requires that the aircraft be energetically
self-sufficient, and the most promising way of
achieving this is the use of solar electric power.
Keeping a solar powered aircraft aloft through the
night, requires storing surplus electric power during
the day for use at night. A lightweight proton
exchange membrane (PEM) electrolyzer to convert
electric power into hydrogen and oxygen in
combination with a lightweight PEM fuel cell to
generate electricity at night offers the means for
achieving this. The performance needed requires
lighter fuel cell and electrolyzer hardware than is
currently available. Equipment meeting these needs
can be economically fabricated through the use of a
combination of lightweight metal and polymer
components. The metal components can be
protected from corrosion using little, if any precious
metal plating, and bonded metallurgically to achieve
the highest possible internal conductivity, while
allowing the greatest reduction in mass.
Potential Commercial Applications (Limit 200 words)
The potential commercial applications for HALE
aircraft include meteorology, where they can make
detailed observations to support forecasting and
storm tracking, environmental monitoring, forest
fire detection, tracking and monitoring marine life,
multispectral imaging for locating mineral deposits,
and long range communication relays in sparsely
populated areas. The same lightweight fuel cell and
electrolyzer technology that is required as an
enabling technology for HALE UAVs can also be
used to produce lighter weight and more compact
PEM fuel cells for terrestrial applications, such as
clean portable power units and zero pollution
vehicles.

Hybrid Propulsion System for
Very-High Altitude Subsonic Aircraft
Technical Abstract (Limit 200 words)
A hybrid propshaft/jet propulsion system is
implemented with a novel piston engine that can
provide either or both shaft and gas power
regardless of atmospheric density. Utilizing a
facultative adiabatic internal-combustion engine
(FAICE) experimentally demonstrated to be
capable of delivering shaft power with and without
aspiration, a controllable hot gas generator for
producing useful reaction propulsion at high
altitudes and low airspeeds is shown. Fueled by
direct-injected nitromethane and backpressured
with a variable area expansion turbine, the engine
combustion power available is divided between
shaft power produced by the expansion of the
combustion products against a piston and by
expansion in a turbine driving a ducted-fan-powered
jet to produce reaction on the vehicle. Maximum
subsonic motive power is found to occur when the
high enthalpy, low mass flow engine exhaust
products are used to augment the total mass flow
ejected and to moderate the ejection velocity by
aspirating, compressing and mixing with available
ram air. Additional impulse energy is shown to be
available by liberating the residual chemical energy
of the underreacted exhaust gases through catalytic
ignition and combustion in the duct with the
inducted air prior to final expansion to ambient
pressure.
Potential Commercial Applications (Limit 200 words)
The performance of very-high-altitude aeronautical
and reusable aerospace vehicles can be enhanced
by using a combination of shaft and reaction power
capabilities available from a hybrid internal
combustion engine that can operate with and
without air to minimize consumption and fixed
weight. Such an engine has application to
maneuverable and recoverable single-stage-to-orbit
spacecraft as well as high-altitude atmospheric
research aircraft. Variations of the system have
merit for general aviation aircraft as well.

Project Title: Distributed Fiber Sensor for Aerospace Stress Monitoring and Vibration Analysis
Technical Abstract (Limit 200 words)
Physical Optics Corporation (POC), proposes to develop a state-of-the -art structural monitoring system using a distributed array of strain- sensitive fiber Bragg gratings with an optoelectronic demultiplexer sensor read-out system that directly delivers stress and vibrational analysis data. The ultimate goal is to develop and deploy a structural health monitoring system with sensor fibers forming an integral part of the critical structural elements in an aerospace vehicle. The fiber Bragg grating arrays will be temperature- compensated by independent temperature measurement and software temperature correction. The grating demultiplexing system will measure slowly varying strains at 1-2 Hz caused by constant load applied to the structural elements, as well as higher-frequency vibrations up to 1 MHz from vibrations due to air flow along the aircraft or spacecraft. Since the optical system is capable of operating at ultrasonic frequencies, with a change of the data acquisition, the system can also be used to detect laser ultrasound NDE. In Phase I, POC will fabricate a benchtop model multiple-fiber Bragg grating structural sensing array with demulti- plexing instrumentation and software temperature compensation to prove this technique is suitable for monitoring quasi-static strains and higher frequency vibrations in NASA vehicles.
Potential Commercial Applications (Limit 200 words)
A system that permits continuous multi-point monitoring of strain and vibration inside structural elements would have a large number of commercial applications. The technology could be used in commercial aviation construction and in e automotive industry. Instruments based on this system could also be mounted on the thousands of deteriorating U.S. bridges and overpasses to monitor their structural integrity, and could be incorporated in other civil structures (e.g., buildings, roadways) as well.

Multimeasurand Optical Fiber Sensors
for Flight Test Applications
Technical Abstract (Limit 200 words)
Optical fiber sensors are rapidly emerging to
replace conventional electrical-based sensor
instrumentation in specific applications where small
size, low mass, multiplexing capability, and high
temperature resistance is a requirement. The
advantages offered by state-of-the-art optical fiber
sensors are particularly important for flight testing
applications where the extremely low-profile
geometry of a hair-thin optical fiber sensor permits
precise measurements of pressure, temperature,
skin friction, and heat flux with minimal intrusion
into the flow field. F&S, Inc. and researchers within
Virginia Tech's Aerospace Engineering
Department propose to develop a novel combined
optical fiber pressure, temperature, and skin
friction gage for distributed hypersonic flow
measurements during aircraft testing. The Virginia
Tech subcontract will be under the direction of Dr.
Joe Schetz who is a world expert in the modeling
and measurement of complex flow fields and the
first researcher to simultaneously measure skin
friction and heat flux at a single location. During
Phase I, together with Dr. Schetz, F&S proposes to
leverage previous experience in the development of
combined optical fiber pressure and skin friction
sensors developed primarily for wind tunnel
applications and investigate the feasibility of
miniaturizing and ruggedizing these sensor arrays
to make them compatible with the harsh aircraft
environment.
Potential Commercial Applications (Limit 200 words)
In addition to NASA's need for high-performance
optical fiber sensors for flight test applications,
there is a large commercial market for such sensors
for wind tunnel test applications, transportation
system design, development and operation,
semiconductor fabrication, commercial jet engines,
automobile engines, the metal, ceramic and wood
processing industries, and the power generation and
monitoring systems for coal-fired, nuclear and

within the government such as Air Force, NASA,

Project Title: Sub-Scale Remotely Piloted Micro-Turbine Powered Hypervelocity Shape
Technical Abstract (Limit 200 words)
SWB Turbines offers Phase I integration of transonic Micro-Turbine propulsion into a sub-scale remotely piloted vehicle of a candidate hypervelocity shape. Construction of a dual-purpose mock-up has a primary purpose to provide a means to investigate flight control systems, engine integration, cooling schemes, fit of the propulsion system mounts, and mass distribution issues. The secondary purpose of the same mock-up is that it may be transformed, in a labor-saving manner, directly into a male-plug from which a Phase II female mold can be constructed. The innovative shape proposed is more rapidly realized in a Phase II flight demonstrator, using this process. Additional innovations include the use of a transonic micro-turbojet propulsion system, in a form directly off-the-shelf with 70 lbf thrust (1997), or in an advanced low-frontal area form from 140 lbf thrust (dual SWB-2, NAS3-97068) to 350lbf thrust in advanced SWB-2 cycles (afterburner, ramjet, turbo-rocket) and a minimum diameter high thrust engine (NASA 97-1 Phase I).
Potential Commercial Applications (Limit 200 words)
SWB Turbines has determined that sub-scale testing of advanced shapes provides a cost-effective means to study vehicle flight performance. International interest in hypervelocity vehicle has increased, in recent years, and continues to create a market niche that offers considerable spin-off, including development and testing of advanced cycle sub-scale propulsion, CAD to CNC conversion methods for aero shape production, and potentially breaking new ground for future commercial air travel industry.

Project Title Flight Tests of the Low Speed Characteristics
of a Hypersonic Waverider Configuration
Technical Abstract
A series of flight tests of the LoFLYTE(TM) aircraft are planned, with the goal of fully
characterizing LoFLYTE(TM)'s aerodynamics, evaluating possible modifications and
enhancements to the aircraft, evaluating LoFLYTE(TM)'s neural adaptive flight control
system, and verifying the controller's generiticity. In the former area a series of flight
tests directed towards the exploration of LoFLYTE(TM) flight envelope, characterization of
its SERN nozzle, and elimination of the dutch roll phenomena are anticipated. In the
control area, flight tests designed to evaluate the performance of the flight controller in
extreme environments; in the face of aircraft modifications, system failures and/or
aircraft damage; and under fully autonomous control are anticipated. A Flight Test Program
Plan will be developed to ensure safe and efficient
conduct of the flight test experiments.
Potential Commercial Applications
Fully developing the low speed characteristics of a hypersonic waverider configuration with
an advanced neural vehicle management system provides several near term applications of the
resulting technologies to subsonic, supersonic and hypersonic flight vehicles. The benefits
of this program exhibit tremendous longer term potential applications to operational
military and civilian vehicles. Research applications include subsonic target drone
applications, Mach 2 to 4 ramjet powered vehicles and Mach 4 to 8 dual mode ram/scramjet
powered vehicles. The United States Navy in its Mission Needs Statement has identified the
requirement for a hypersonic vehicle for military
missions.

Project Title: Flight Demonstration of EM Enabling Technologies for Hypersonic Vehicles
Technical Abstract (Limit 200 words)
Utilizing plasma and electromagnetic interaction on hypersonic vehicles for aerodynamic control, drag reduction, thermal management and propulsion is being explored in aeronautics. Innovative schemes have been proposed by US agencies and industries and foreign governments, e.g., the Russian AJAX. This SBIR will to explore this subject and produce hardware for plasma/EM systems that form "Enabling Technologies" for advanced hypersonic aircraft.
National initiatives in hypersonic vehicle development will lead to flight vehicles within the next five years. Both the Hyper X and HySID programs have this purpose and provide unique opportunity to host experiments to explore EM concepts/systems at actual conditions. Their timeline is ideal to provide the testbed for Phase's II and III.
The Phase I SBIR program will peform R/R&D to screen plasma/EM/MHD/MGD hypersonic vehicles and propulsion concepts and identify those enabling technologies for advanced vehicles within the next decade. The work plan combines scientific assessment of hypersonics subject to plasma/EM phenomena with aircraft design and propulsion engineering. It will perform analysis, engineering, system trade-off and vehicle integration studies to select systems for development in Phase II. Phase I will define a Phase II technology "road map" for verification in laboratory and flight tests to produce flight hardware for Phase III.
Potential Commercial Applications (Limit 200 words)
The plasma/EM technologies are cited for direct commercial application to future, advanced hypersonic vehicles that are under development by NASA and other government agencies under national aeronautic initiatives. It is envisioned that a many potential commercial applications will also exist for related "spin-off" technologies that will be derived from this program. Among these are methods/devices for air plasma production, active flow manipulation, electromagnetic plasma power generation, lightweight/compact high field magnets,
etc., with application to areas/markets that include U. S. government agencies (e.g., NASA, DoD, DOE), ground test facilities, aircraft manufacturers,
commercial diagnostics, utilities, and research institutions.

Project Title: Minimum Frontal Area High-Thrust Engine
Technical Abstract (Limit 200 words)
SWB Turbines proposes to develop a minimum frontal area high thrust turbojet engine, ultimately suited for hypersonic shape vehicle propulsion. A diameter of 5" is achieved with a two-stage compressor, yielding 174 lbf thrust, SLS. Advanced aerodynamical design of the rotating components is achieved, resulting in a 10:1 pressure ratio operating regime, at full thrust. Innovations enabling a frontal area specific thrust of 8.9 lbt/in2 at low cost include high-efficiency aerodynamics with mixed flow two-stage compressor, uncooled net-shape cast combustor liner, high-work single stage mixed flow turbine with simple vaneless exhaust, and other innovations adapted from a line of micro-turbojet engine technologies. A unique team of SWB Turbines and Sundstrand Power Systems enables rapid engine prototyping, and the offering of an innovative, low-cost casting approach for the hot sections. Previously developed SWB turbojet engines SWB-3, SWB-4, SWB-5) for similar applications have proven to be very reliable and have exceeded specifications, logging many hours in both test cell and unmanned aerial vehicles. Previously developed Sunstrand engines include the TJ-50 turbojet, TPR-80 turboprop, and the ATR-120 air-turbo-rocket engine. Sundstrand also provides a cost share initiative to the Phase II effort.

Project Title: PASSIVELY METERED FILM-TRANSPIRATION-REGENERATIVE COOLED STRUCTURAL PANEL
Technical Abstract (Limit 200 words)
A hypersonic engine application may require a sophisticated system to maintain the hot wall structure of the combustion chamber within structural temperature limits. Insulation protects the structure for single mission requirements, but regenerative cooling is required for reusability or severe flight envelopes. At the upper limits of the hypersonic engine operating envelope, transpiration film cooling may be required, possibly in indeterminant localized regions due to combustion variations or operating requirements. A hybrid hot-wall cooling panel is proposed which incorporates a regenerative cooling design that will automatically add localized film cooling when the hot wall reaches a critical temperature where regenerative cooling is insufficient to maintain structural integrity. Film cooling is injected along the surface at local hot spots or throughout the panel for general high temperature operation to augment the regenerative cooling. The film coolant is injected at multiple discrete locations along the boundary layer to minimize local flow disturbances and to prolong the effectiveness of the film isolation of the hot combustion gases from the cooled wall for the longest distance; thus minimizing the amount of added coolant flow required to maintain acceptable operating wall temperatures. Automatic injection of film coolant is accomplished by thermally activated hot wall elements.
Potential Commercial Applications (Limit 200 words)
Next generation aerospace engines will operate at significantly higher temperatures both for military and commercial transport. This innovation will service these advances. Other applications include a hazardous waste incinerator which could benefit from the higher combustion temperatures provided by the cooling panel concept, which also can accommodate varying temperatures as well. Turbojet afterburner ducting for military and commercial aircraft could also benefit from the cooling panel formed in an axisymmetric configuration.

Project Title:
Large-Scale Performance
Improvements of RBCC Engines Using
the Dynamic Ejector
Technical Abstract (Limit 200 words)
A unique and innovative approach to significantly
increasing the thrust performance of
ejector-configured, rocket-based combined-cycle
(RBCC) engines is proposed. The approach
involves oscillating (switching) the rocket exhaust
at high frequency (the dynamic ejector), rather than
permitting it to simply flow coaxially with the
induced air as in a conventional ejector
configuration. Since the sole mechanism for
transferring momentum and energy between the
two streams in a conventional ejector is viscous
shear through turbulent jet mixing, very large
losses result. This leads to lower thrust levels
(hence, specific impulse) than those achievable
using a more efficient method of momentum and
energy exchange. It is shown herein that oscillation
of the rocket exhaust using secondary fluid
injection (as in thrust vector control techniques)
results in a far more efficient transfer of momentum
and energy, leading to very significant increases in
specific impulse, probably in excess of 50% thrust
augmentation. The proposed concept is responsive
to the solicitation's subtopic calling for "high thrust
performance of ejector-ramjets...at take-off of the
hypersonic vehicle..." Indeed, the performance
benefits derived from the proposed concept occur
principally at take-off.
Potential Commercial Applications (Limit 200 words)
Ejector ram/scramjets will be found to be a cost
effective, high performance propulsion system
technology in the near future. The participants in
NASA's ARTT program have already committed to
this technology. We will seek to move the
technology developed in Phases I and II into
prototype and full-scale engine development in
Phase III, with application to three market sectors:
the military, civil and commercial marketplaces,
both domestic and foreign. The Phase III objectives
will be to continue the process of evolving the
integrated, dynamic ejector-based, RBCC ejector
ram/scramjet, and further reducing the technology
risk through system demonstration at the
prototype, then full-scale level. The reduction of
technical risk is a required precursor to the
reduction of business risk. This, then, is a precursor
to positive investment decisions.

Project Title:
A Pulsed Detonation Engine Ejector
Concept for High Performance
Propulsion
Technical Abstract (Limit 200 words)
MSE Technology Applications, Inc. (MSE)
proposes to evaluate and test a Pulsed Detonation
Engine-Ejector (PDEE) concept for hypersonic
vehicle design. Due to its high specific
performance, design simplicity, and low weight, the
Pulsed Detonation Engine (PDE) is a good
candidate for the low-speed propulsion system for
hypersonic vehicles if the PDE thrust levels can be
increased. This cannot be easily accomplished by
increased pressurization, and there is a practical
size limit on the PDE that can be integrated into the
vehicle. The ejector concept solves that problem by
using the mass flow of a secondary stream for
thrust augmentation. Using the Ramjet/Scramjet
engine as the secondary channel makes use of
existing hardware and does not increase the overall
engine weight. The proposed engine design relies
on the unsteady ejector concept, which is proven to
be much more efficient than the steady ejector,
such as the Rocket-Based Combined-Cycle
(RBCC) engine. This innovative concept also
extends the combustion regime of previous
unsteady ejector designs to the detonation mode,
which can produce higher ejector performance. The
proposed PDEE can therefore simultaneously
achieve the high specific impulse and high
thrust-to-weight required for single-stage
hypersonic vehicles.
Potential Commercial Applications (Limit 200 words)
The proposed PDE-Ejector concept can be used for
the design of the low-speed propulsion system for
hypersonic vehicles. The successful design of this
engine component is extremely important for
NASA, the Air Force, and several private-sector
companies interested in the manufacture of
reusable launch vehicles for the placement in orbit
of a constellation of satellites. The concept can be
applied to large reusable hypersonic vehicles or as
boosters to expendable vehicles. Further
refinement of the technology, notably
miniaturization and soundproofing can also lead to
cruise missile applications and the design of
propulsion systems for a wide range of military and
civilian applications. MSE is also presently
collaborating on PDE technology development with
United Technologies Research Center (UTRC) and
Pratt & Whitney, who may be partners in the
proposed R&D effort and in the commercial
development of the technology.

Novel Conformal Sandwich Panel
Structures
Technical Abstract (Limit 200 words)
The proposed program will demonstrate the ability
to produce novel conformal titanium sandwich panel
structures. Specifically, techniques will be
demonstrated for controlled thermal spraying and
selective laser sintering of functionally gradient,
conformal, porous titanium structures. Further
enhancements to the specific stiffness will be
achieved through an innovative process enabling
ceramic microspheres to be co-sprayed with a
titanium matrix. The resultant structure will have
controlled porosity varying from 0-60%, with
graded distributions of both porosity and ceramic
fillers. Structures fabricated using the proposed
process will be suitable for use in high speed flight
vehicles and space structures including cryogenic
tanks, cowlings, thermal protection structures and
substructures, and other flight vehicle structures.
The program will develop, using laser fusion and
thermal spray techniques, titanium structures
graded from 100% dense to less than 50% dense in
a relaible, repeatable manner. The processing
method relies on the use of innovative sintering aid
titanium encapsulated metal powders and fillers and
controlled heat input during thermal spray
deposition. This spraying of semi-solid particles will
result in a fully dense deposit ranging from 30 mils
to over 1/2 inch in thickness.
Potential Commercial Applications (Limit 200 words)
Anticipated Program Results: Successful
completion of the proposed program will result in
thermal spray/lasar fusion parameters and
microentineered raw materials enabling the buildup
of conformal Ti structures ranging from fully dense
to 60% porous in a repeatable, controlled manner.
These structures will ifnd applications in launch
vehicle structures, including thermal control
structures for operation at 400-800 degrees C,
aircraft structures, combustion engine structures,
injectors, and corrosion resistant coatings.

Prediction of Launch Vehicle Ignition
Overpressure and Liftoff Acoustic
Environments
Technical Abstract (Limit 200 words)
The proposed research addresses a problem of
importance to the design of both expendable and
reusable launch vehicle structures and the satellites
they carry. During rocket engine ignition at liftoff, a
shock wave and exhaust gas mass flow are
produced which interact with the launch pad to
generate pressure waves (Ignition Overpressure or
IOP) that impact the vehicle and cause both
overpressure loading and acoustic concerns. In
addition, the rocket plume generates acoustic
waves which, in turn, interact with the launch pad
geometry and impact the launch vehicle.
The proposed work will extend an existing
simulation of rocket ignition and plume generated
overpressure and acoustic fields to a wide range of
launch vehicles and launch facilities and allow rapid
determination of the structural forcing functions
imposed during launch.
An existing database of Shuttle and Titan data will
be expanded to include all available flight and test
data. The data will be characterized in terms of the
rocket and launch complex characteristics. Selected
data records will be employed to validate the
numerical predictions. Code modifications will be
completed during Phase II of the project.
Potential Commercial Applications (Limit 200 words)
The application of this technology to commercial
launch vehicles and satellites will enable the
determination of critical design loads when
launching a payload on any particular launch
vehicle at a selected launch complex and will offer
methods to predict mitigated overpressure and/or
acoustic environments if the payload and/or launch
vehicle survival is in question.

Project Title: Magnetic Compression of Colliding Spinning Micro Tori for Fusion Space Propulsion
Technical Abstract (Limit 200 words)
A compact fusion rocket burning the two nonradioactive fuels: deuterium and helium 3, both space resources, would enable NASA to conduct ambitious commercial, robotic and human exploration. The D-He3 fusion reaction is particularly attractive for space propulsion because its reaction products are energetic charged particles, which can be shielded and confined by magnetic fields. The key physics of this fusion rocket concept are the collision and magnetic compression of spinning FRCs (Field Reversed Configuration) plasma tori. The tori are heated by compression to thermonuclear temperatures. D-He3 fusion will heat the plasma, causing it to react back against the magnetic field, recharging the compression circuit and expelling plasma as rocket exhaust. This device would have high pay-off commercial power generation applications on Earth, and has the potential to reduce cost and increase performance of deep space propulsion systems. The important aspect of this concept addressed in this proposal is the demonstration of feasibility of the magnetic tori collider-compressor. An existing experiment, CMTX (Colliding Micro Tori eXperiment), will be upgraded for stronger compressions of the collided tori with the goal of 10KeV ion temperatures. This will allow rapid transition to Phase II work in which actual D-He3 fusion reactions will be triggered.
Potential Commercial Applications (Limit 200 words)
The harnessing of D-He3 fusion in a compact reactor-rocket engine would create an energy-space economic synergism and dramatically increase commercial activity in the space frontier leading eventually to a multi-planetary economy. It would lead to a He3 based energy economy for Earth, since the compact reactor can be modified to produce electric power instead of thrust for terrestrial use. Lunar and later planetary He3 mining would then allow cheap non-greenhouse, non-radioactive waste producing electric power for the terrestrial economy while leading to massive expansion of human activity into the solar system.

Rocket Thrust System for Reusable
Launch Vehicle Powered by the QED
IEF Power Plant
Technical Abstract (Limit 200 words)
The QED Engine concept offers to the space
program of the 21st Century
a potentially economical means of space access
using single-stage to
orbit and highly reusuable launch vehicle
technologies. Based upon
the posited existence of a compact, lightweight
fusion electric power
source, the QED Engine involves the conversion of
fusion power into
the heating of a working fluid whose subsequent
expansion produces
thrust. The specific innovation proposed here is the
means by which
this power coupling is achieved, and in how the
heated propellant is
to produce thrust. In the proposed effort, the
coupling of power from
an electron beam into a plasma for the purpose of
heating the plasma
to conditions appropriate for producing thrust will
be examined. The
expansion of the heated plasma through a nozzle
created by a carefully
tailored magnetic field, and how this magnetic
nozzle and the plasma
parameters can be configured to optimize thrust will
also be examined.
Phase I will culminate in an understanding of the
appropriate
parameter regimes for the electron beam, the
in-flowing working fluid,
and the magnetic field of the nozzle. This will lay the
groundwork
for more specific investigations and
experimentation.
Potential Commercial Applications (Limit 200 words)
The effort proposed here forms the basis of a larger
and longer term
effort whose success will result in a widespread
commercialization of
space. Involvement of the private sector in
developing early
engineering models of the QED Engine will produce
the earliest
commercial returns from licensing agreements
involving technology

Project Title: Demonstrate the Feasibility of fabricating a Dual Microstructure YBCO Toroid Suitable for Gravity Shielding Experiments
Technical Abstract (Limit 200 words)
Results published by E.E. Podkletnov (1) describe a multiphase YBCO superconductive disc which, when levitated and rotated at temperatures below 70 Kelvin provides partial shielding of gravitational forces. Attempts by US researchers to duplicate the apparatus and specifically the superconductive toroid have not been completely successful. In the Phase I program we will demonstrate the feasibility of manufacturing a superconductive toroid with dual microstructure similar to that used by Podkletnov. Two approaches will be explored to fabricate small scale discs. The most promising scaleable technique will then be used to fabricate a nominal 8" OD, 2" ID, 0.5" TK superconducting toroid. The core of the toroid will be further characterized by the research team and the toroid itself will be delivered to NASA for further gravity shielding experiments.
Potential Commercial Applications (Limit 200 words)
Large size, melt textured YBCO superconductor is a key component of the Gravity Shielding apparatus described by Podklentov. Gravity Shielding could revolutionize the economics of space vehicles, airplanes, railroads and automobiles.

System for End-of-Life Deorbit of LEO
Spacecraft
Technical Abstract (Limit 200 words)
The Terminator Tether will utilize propellantless
electrodynamic tether drag to provide a low-mass
means of removing LEO spacecraft from orbit at
the end of their operational lifetimes to prevent the
build-up of orbital debris. The Terminator Tether
will be a small autonomous package that is attached
to a spacecraft before launch. When the satellite
fails, or is no longer needed in orbit, the system will
deploy a conducting tether weighing a small
percentage of the spacecraft mass. This tether will
interact with the Earth's magnetic field, generating
a voltage along the tether. The induced voltage will
drive a current along the tether. The interaction of
the current with the geomagnetic field will generate
a force opposed to the spacecraft's orbital motion.
This drag force is sufficient to deorbit the
spacecraft within several weeks or months,
compared to decades or millennia for atmospheric
drag alone. The SBIR effort will develop innovative
concepts for lightweight subsystems for deploying
survivable conducting tethers, controlling the
dynamics of the tether, and emitting electrons from
the negative end of the tether. These innovations
will enable the Terminator Tether to provide a rapid
deorbit method that requires significantly less mass
than a conventional rocket system.
Potential Commercial Applications (Limit 200 words)
The Terminator Tether will find commercial
applications on every satellite and upper stage
placed into orbits between 500 and 1500 km
altitude. Within the next decade, the number of
satellites in LEO will grow rapidly. Unless these
spacecraft are removed from LEO at the end of
their lifetimes, LEO will soon become filled with
derelict spacecraft and orbital debris. The standard
method of deorbiting a satellite is to use rockets.
This method, however, requires that a large fraction
of the satellite launch mass be allocated for deorbit
propellant. Moreover, it requires that the rocket
and guidance systems be functional. The
Terminator Tether can provide rapid deorbit while
requiring only a small percentage of the launch
mass, maximizing the amount of payload mass that
can be used for transponders and stationkeeping
propellant. In addition, it can deorbit satellites even
after the satellite's power and attitude control
systems have failed. Commercial potential is
demonstrated by the fact that Teledesic has
expressed a strong interest in using the Terminator
Tether on their satellites and dispensers, a launch
system company has offered free test flights worth
$4,500,000, and an investment group has expressed
interest in providing $2,000,000-$5,000,000 in
Phase III funding.

HIGH-EFFICIENCY, GAS-FUELED
PULSED PLASMA THRUSTER WITH
ALL-SOLID-STATE DRIVE
Technical Abstract (Limit 200 words)
The objective of this effort is to develop a compact,
efficient, gas-fueled pulsed plasma thruster (PPT)
for space propulsion applications. Pulsed power to
drive the thruster will be delivered via a highly
reliable, all-solid-state nonlinear magnetic pulse
compressor to be optimized specifically for pulsed
plasma thruster applications. Initial
proof-of-concept demonstrations conducted at
Princeton University's Electric Propulsion and
Plasma Dynamics Laboratory (EPPDyL) have
demonstrated up to 50% electrical efficiency with
mass utilization efficiencies approaching 100%. The
thruster has also been designed so as to be
propellant insensitive, opening up the possibility of
utilizing propellants which might be mined at the
destination for the return trip.
Potential Commercial Applications (Limit 200 words)
Successful completion of this SBIR will result in a
new class of efficient, reliable, lightweight electric
thrusters for space-based propulsion. These
thrusters will be suitable for providing either
primary propulsion or stationkeeping requirements
to a vast array of commercial satellites.

Project Title:
Antimatter Production at a Potential
Boundary
Technical Abstract (Limit 200 words)
Current antiproton production techniques rely on
high energy collisions between beam particles and
target nuclei to produce particle and antiparticle
pairs, but inherently low production and capture
efficiencies make these techniques inadequate for
the cost-effective production of antimatter for space
propulsion and other commercial applications.
Based on Dirac's theory of the vacuum field, an
innovative antimatter production technique is
proposed in which particle-antiparticle pairs are
created at the boundary of a steep potential step
formed by the suppression of local vacuum fields. A
quantum mechanical analysis of spin-1/2 particle
tunneling and reflection from a potential barrier is
presented which shows that matter particles will be
reflected from the potential step while antimatter
particles continue through the potential barrier,
where they can subsequently be collected and
stored for future use. Techniques for generating the
required potential barrier are discussed, and an
experimental Phase I research program is outlined
that will demonstrate the feasibility of the proposed
technique for antiparticle production. If successful,
the proposed research will lead to the development
of an efficient, cost- effective method to generate
antimatter in sufficient quantities for commercial
and space exploration activities.
Potential Commercial Applications (Limit 200 words)
If successful, the proposed technology will provide
a cost effective method to produce antimatter in
sufficient quantities for spacecraft propulsion and
other commercial applications, including on-site
medical radiation treatments, nondestructive
material testing, and material processing
applications.

Project Title:
Design of a High-Efficiency Antiproton
Degrader/Accumulator to Support
Advanced Propulsion Research
Technical Abstract (Limit 200 words)
Antiprotons offer the highest potential performance
in advanced space propulsion systems. Several
concepts for using antiprotons for propulsion have
been developed during the past decade. To date,
however, a source of low energy antiprotons to
perform feasibility experiments has not been
available. Because of the recent development of the
high-capacity portable trap developed by G. A.
Smith at Penn State University, the storage
technology now exceeds the production capacity at
the world's acclerators. We intend to design and
computationally verify a new solid-state degrader
that will allow a two order of magnitude increase in
the availability of storable antiprotons. This will
allow the new traps to be filled in hours instead of
months which will enable antiproton reearch to
advance in a number of directions including
proof-of-concept experiments in advanced
propulsion.
Potential Commercial Applications (Limit 200 words)
The potential for commercial applications using
antiprotons is tremendous. Although several
researchers have postulated the need for a portable
source of low energy antiprotons for physics
research and energy source development, the most
promising near term commercial use is in the
production of short-lived, biomedical radioisotopes.
These isotopes are currently used to detect many
forms of cancer using Positron Emission
Tomography. The isotopes, however, are currently
limted to expensive production facilites. A portable
source would allow a 100 fold increase of the
availablility of PET scans across the nation. In
addition to the PET application, antiprotons can be
used in conjunction with proton beam therapy to
precisely locate the end-point position of the proton
beam. Proton therapy is a rapidly growing
procedure at the Massachusetts General and Loma
Linda facilities. Both of these industries could be
revolutionized or enhanced by the development of a
portable source of antiprotons that can be rapidly
refilled. This proposal will enable that technology.

METASTABLE ELECTROEXPLODED
NANOPHASE ALUMINUM BASED
GELS AS A COMPONENT OF
PROPULSION FUELS
Technical Abstract (Limit 200 words)
Aluminum powder is an additive to many
propellants. For more than 60 years attempts to use
it as an energy enhancer for hydrocarbons were not
very successful. Metastable electroexploded
nanosize aluminum powder (Alex), could revitalize
NASA's Metallized Propellant Program. Alex and
other metals produced by the electroexplosion of
metal wire are metastable, producing additional
energy and burning rate. Alex based gels with
water, hydrazine or mixtures of the two, melt as low
as -92C, and burn to produce hot hydrogen at flame
temperatures around 3,200K. Alex may be
passivated by microencapsulation in paraffin
coatings that protects it from spontaneous reaction
with air or reaction in boiling water. Yet, recent
tests show that such Alex when mixed into
kerosene will burn to completion in a
hydrocarbon/air flame, while coarser aluminum in
kerosene could not be ignited or burned at all. The
objectives of the Phase 1 study are to formulate
water and RP-1 gels and test them to determine
combustion characteristics. In Phase 2 we would
perform rocket motor tests to prove the utility of
both Alex/ water as a monopropellant as well as
using Alex to increase the energy and speed of
burning of RP-1.
Potential Commercial Applications (Limit 200 words)
Alex/water gels have application as
monopropellants for small space rockets. They may
also have application as a convenient and energetic
pyrotechnic that can be used as a hydrogen source,
generating heat and light in underwater
applications, and as a heat source in certain welding
and joining applications. Alex additives to
hydrocarbon fuels may find use in ramjets,
scramjets and other air-breathing engines to
enhance the specific mass-energy density of such
engines, and to stabilize their burning. Proving the
utility of Alex gels would enhance the sales of Alex,
already being manufactured and sold by Argonide
for propulsion and energetic applications.

Project Title: Advanced UV Raman Diagnostics for Rocket Engine Tests
Technical Abstract (Limit 200 words)
To contain the increasingly high costs of ground test data, development of advanced, non-intrusive diagnostics which are capable of generating reliable, quantitative flow field information is imperative. Laser diagnostics have the potential to provide a cost-effective measurement tool for ground tests. Spontaneous Raman has been successfully applied to high pressure rocket engine tests for the qualitative measurement of major species and temperature. By analytically and experimentally addressing issues concerning system calibration, laser-induced interferences, and stimulated Raman processes, we anticipate the development of an advanced quantitative Raman system for rocket engine test applications. This diagnostic will be of direct benefit to a wide range of difficult measurement applications such as a rocket-based combine cycle or hybrid rocket motors.
Potential Commercial Applications (Limit 200 words)
An advanced Raman diagnostic system capable of quantitative species and temperature measurement will enjoy a wide commercial appeal. Endeavors which are particularly attracted to this technology are automotive and marine engine research, aerospace propulsion testing, wind tunnel testing, CFD validation experimentation, environmental monitoring, and process control.

Project Title:
Emission tomography for non-intrusive
three-dimensional measurements of
density, temperature, and chemical
composition in rocket engine plumes
Technical Abstract (Limit 200 words)
This proposal presents an economical instrument
for making global measurements of density,
temperature, and constituent concentration of
rocket engine plumes. This innovative technique is
based on collecting emitted flame radiation from a
large number of viewing angles; the irradiance
depends on the integrated effects of gas and
particulate temperature and species concentration
along the optical path. Using a large number of
intersecting optical paths allows the resulting set of
radiative transfer equations to be inverted to obtain
the spatial temperature profile of the flame or
plume. This emission tomography approach is
appealing because, unlike conventional
transmission tomography, neither probe beams nor
their associated optics are required. Therefore,
only simple optical access to the combustion
chamber is required to implement this technique.
Emission tomography can be used with both
stimulated and spontaneously emitted radiation,
and spectroscopic methods may be used to isolate
the concentration of one or more constituents. By
using two emission lines of a known species, the
temperature may be extracted by a simple two color
technique. Prior simulations and experiments
presented here illustrate that with simple optical
geometry and a single camera, the reaction zone of
a diffusion flame may be accurately identified; this
illustration applies equally well to temperature
measurement. Iterative algorithms are necessary to
account for self-absorption and refraction effects.
This technique may also be applied directly to other
gas phase processes.
Potential Commercial Applications (Limit 200 words)
The proposed instrument will provide three
dimensional density, temperature, and constituent
concentration measurements using spectroscopic
emission computed tomography. This instrument
will be useful in both research and industrial
monitoring applications, having applications in
areas requiring three dimensional measurement.
Significant applications include high temperature
gas dynamics, welding, plasma spray, and other gas
phase flows.

Project Title: Propellant Leak Detection System(709CR2067)
Technical Abstract (Limit 200 words)
Current liquid leak detection methods rely on electrically coupled analyzers which in fact analyze for vapor already present in the environment. A passive, non-invasive technique which detects leaks AT THE SOURCE would speed up the leak detection process, decrease the total leakage, and decrease the hazards associated with ignition sources in proximity to the propellant and worker exposure. Mainstream proposes the use of fluorescent leak detection, the compounds being specifically designed to the fuel so as not to degrade the performance of the system. This is possible since many compounds we have identified for use in these systems are actually performance improvers, and the concentrations needed to produce a fluorescent signature are only fractions of a percent. The detector light and compounds are patent-pending technologies of Mainstream for related applications, and the transference of the innovative systems to advanced propellant systems is the next natural progression. Phase I will optimize and match these compounds for specific advanced propellant systems, and Phase II will package the entire system into prototype, field-use design for prove-out testing by NASA.
Potential Commercial Applications (Limit 200 words)
The development of a passive, non-invasive leak detection technology has applications in the commercial and government space launch industry, in addition to commercial and military aircraft. This technology will increase safety during missile launch, servicing, and handling of volatile fuels. A detector such as this could also be used as part of a fuel "tag" program, and in assisting the development of new, advanced commercial jet fuels.

Project Title: Miniature PCR/ Fluorogenic DNA Probe Biosensor for Space
Applications
Technical Abstract (Limit 200 words)
SPEC, in collaboration with Dr. Carl Batt of Cornell University, has developed a design for a miniature biosensor capable of performing PCR and fluorometry in a single compact chamber for target amplification, detection and identification. In the Phase I, SPEC will construct a breadboard instrument for use in demonstrating proof of concept of this novel device for molecular biology, environmental, and medical applications in space. SPEC and Dr. Batt will explore the use of DNA probes with fluorogenic direct hybridization and PCR-based assays for detection and quantification of DNA, RNA, and oligonucleotides in a microgravity environment. These two distinct nucleic acid chemistries both have as the basis for their detection a reduction in the quenching of the intact probe molecule when the target template is present. In both formats, a fluorescent reporter dye covalently linked to an oligonucleotide probe is quenched by a second dye molecule also attached to the probe. The release of quenching, due to either the unfolding of the probe or the hydrolysis of the probe, is measured by fluorometry and is quantitative. The prototype instrument to be built in the Phase II will be small (3inx3inx5in), low power, low weight, and self-contained for use in microgravity.
Potential Commercial Applications (Limit 200 words)
The development of a small, highly sensitive, DNA probe instrument capable of providing rapid results has significant commercial applications as home diagnostic devices, medical research tools, food processing monitors, clinical instruments and environmental detectors as well as for NASA and the Department of Defense. DNA probes can provide high specificity in the detection of genes, pathogens, and environmentally hazardous biological organisms. This instrument will combine the specificity of DNA probes with the sensitivity of PCR amplified fluorometry.

Project Title: Modular System of Microscopic Observation Chambers for the Study of Fluids and Living Systems
Technical Abstract (Limit 200 words)
Improved techniques for microscopic observation of cells, proteins, microcapsules, and fluids in general, are commercially important for both space and ground-based research laboratories. Modular components, which can be configured to function in multiple applications, compose an innovative system of microscopy equipment. A uniquely designed hollow microscope slide offers an opportunity to study the effects of magnetic fields, electrokinetic fields, and microscopic hydrodynamics on a wide range of fluids and biological samples. The key element of the system is the hollow slide, which interfaces with other modular components, providing novel opportunities to manipulate the sample. Three sets of endcaps, each specifically designed to accommodate magnets, electrodes, or pumps, offer flexibility, stringent control of the applicable field, and user-friendly interfaces for the investigator. Now, rather than maintaining a large inventory of different slides and culturing dishes, the investigator can purchase a modular system of components that can be assembled to perform a multitude of experiments and variety of field application research. Whether used in the gravity-free environment of space or in ground-based research and analytical laboratory applications, our modular observation chamber system has the potential to be an efficient technique for observing specific biological components in, or interactions between, fluid materials.
Potential Commercial Applications (Limit 200 words)
Commercial applications will capitalize on the widespread need for unique microscopic observation techniques both on earth and in the low gravity environment of space. The commercial product anticipated from this proposed research program is an innovative microscopic observation system for use in both space and ground-based laboratories. Such a system has potential applications in areas such as magnetically delivered therapeutics, electrokinetic phase demixing, particle aggregation in electric fields, electrophoretic mobility of particles and drops, and the motion of solutes in simulated iontophoresis. Microscopic observations of interfaces provides an opportunity to examine: the coalescence process in aqueous two-phase systems; solutocapillary motion during macrovoid formation; macromolecular crystallization when free diffusion is used as the crystal growth method; and tracking of solute movement in simulated transdermal delivery experiments. Additional spin-off products and services are expected to have broad applications in numerous scientific and medical research fields; hence, the market for our technology is the widely segmented biomedical field. While our technology will have broad global applications in the ground-based markets, our target market niche is application of the technology in the unique environment of space in the glovebox on the International Space Station.

Project Title: Metabolite/Chemical Monitoring Using Molecular Imprint (MI) Technology
Technical Abstract (Limit 200 words)
Systems & Processes Engineering Corporation (SPEC) and Dr. J.P. Chambers of University of Texas at San Antonio propose to use molecular imprinting (MI) technology to fabricate artificial receptors for the detection of mechanistic biomarkers/chemicals. The MI technology will provide a means of developing receptors for metabolic/chemical biomarkers which currently do not exist. The need for a metabolite/chemical measurement system is critical to assessing animal or human physiology and growth in space environments. A number of protease enzymes and metabolites have been used to evaluate mechanistic responses to various physiological and environmental stresses, and growth stimulates, by immunological and immunoassay methods. However, for a number mechanistic biomarkers, no biochemical sensing/receptor components are available for biosensing applications. Furthermore, with existing sensing elements including enzymes, antibodies and lectins, requirements such as stability cannot be guaranteed. In Phase I, SPEC and Dr. Chambers propose to develop and demonstrate the MI technology for biosensor detection of a candidate biomarker of interest to NASA. In Phase II, SPEC will proceed to develop, construct and fabricate a prototype MI biosensor for biomarkers/chemicals
Potential Commercial Applications (Limit 200 words)
The development of compact, stable biosensors based on MI receptors has significant commercial applications as home diagnostic devices, medical research tools, food processing monitors, clinical instruments and environmental detectors as well as for NASA and the Department of Defense. In addition to its use for biomarkers/chemicals in humans and animals, the MI biosensor can be used to detect toxins, dangerous chemicals, and hazardous environmental agents. MI devices could significantly impact on the projected half-billion dollar market for biosensors in the year 2000.

Project Title: Bioregenerative Testbed Unit for Integrated Animal/Plant Research
Technical Abstract (Limit 200 words)
Biologically closed life support systems will be extremely important in all aspects of longer duration future space flight and have significant potential application to improved recycling techniques for ground application. A key feature in the performance and functionality of a biologically closed life support system are the gaseous and liquid flows between plant and animal components. ORBITEC proposes the preliminary design and prototyping of critical elements that will allow monitoring of the gaseous and liquid exchanges between sealed plant chambers and a sealed rodent chamber on Space Shuttle or Space Station. The Biomass Production System developed by ORBITEC is significantly modular to accommodate independent plant and rodent environments with the capabilities of metering liquids and gases into and out of the chambers. This enables analyses of the quantity and quality of exchanges between the two environments. The SBIR will bridge the existing plant-only systems into an integrated plant/animal facility with sufficient separation between plant and animal habitats to allow monitoring of gas and liquid transfers.
Potential Commercial Applications (Limit 200 words)
The BTU will be provided to NASA as an operational facility similar to BPS and offered to users through commercial means (e.g., direct purchase, lease, lease through SpaceHab). Through the SBIR process, development becomes streamlined in a more commercial vain and actual flight products have resulted that perform better than state of the art. The system could be provided for ground-based research such that scientists could run preparatory experiments and ground controls.

A digital holographic monitor for
protein crystals and materials science
Technical Abstract (Limit 200 words)
Proposed innovation: Holographic methods
measure how crystallization parameters influence
protein crystal size, quality, and growth rates.
Traditional holography is labor-intensive and
difficult to use in-orbit. We propose a Digital
Holographic Monitor (DHM) that records on a
CCD array and numerically reconstructs
interferometric and high resolution images in near
real-time.
Project objectives: The central goal is to
demonstrate digital holographic recording of crystal
growth and important materials science parameters
such as temperature and concentration. We build on
and tailor technology we developed for marine
applications.
Effort proposed: (1) Determine measurement
parameters and operational constraints; (2)
construct test samples and record holographically;
(3) verify critical modules under flight conditions;
and (4) develop a Phase II DHM design.
Results anticipated: Phase I results should include
a detailed Phase II DHM design and development
roadmap. The Phase II DHM will be a near flight
prototype.
Expected NASA applications: The DHM supports
experiments such as the Interferometric Study of
Protein Crystal Growth (IPCG) that differentiate
low-g growth from the ground-based process. The
DHM is also valuable for materials science
experiments in fluid mechanics, mixing,
solidification, and other processes that require
monitoring of density fluctuations or high resolution
imaging through deep depths of field.
Potential Commercial Applications (Limit 200 words)
In addition to the proposed biotechnology and
materials science applications, holography has
proven useful in non-destructive testing, surface
characterization, and particle classification and
monitoring. A compact, robust, and stable
instrument such as the DHM should be important
for high-precision industrial monitoring and testing
and environmental sensing.

A Validated Computational Model to
Enable Real Time Control of the Pulsed
OMCVD Process for Heteroepitaxy of
Compound Semiconductors
Technical Abstract (Limit 200 words)
Pulsed Organo-Metallic Chemical Vapor
Deposition (OMCVD) is being investigated for
ground-based and microgravity applications by
NASA and North Carolina State University (NCSU)
as an effective technique to eliminate defects
during heteroepitaxial growth of compound
semiconductors. This technique requires tight
process control to regulate the sequence and
duration of pulses in response to instantaneous
growth patterns. It is proposed to develop and
validate an advanced computational tool as a
critical enabling technology for process control for
pulsed OMCVD.
Phase I will focus on developing a kinetic model for
the surface reaction pathways during OMCVD. The
model will be tested by implementation into an
existing CFD code. A multi-dimensional
computational model will be developed for the
NCSU OMCVD reactor and detailed simulations of
flow, heat/mass transfer and gas/surface chemistry
will be performed. The model predictions for
ground-based growth will be validated against
measured NCSU data . The model will also be used
in support of the NCSU space flight experiment
design and operation. The Phase II work will focus
on extensive validation of the chemistry models
over a range of operating conditions. Advanced
Monte Carlo models will be applied to understand
the microstructural evolution of the film. A series of
parametric simulations will be performed to
determine optimal operating conditions for the
reactor. The model will be fully validated using
ground-based and microgravity flight data.
Potential Commercial Applications (Limit 200 words)
Heteroepitaxy of compound semiconductor
materials on heterogeneous substrates is a vital
technology for optoelectronics in the blue to
ultra-violet wavelength region and non-linear optics
in the infra-red region and power devices and
integrated sensor devices. The proposed model will
be an enabling technology in demonstrating
defect-free heteroepitaxial growth by facilitating
appropriate control of the pulsed OMCVD process.

Project Title:
Gasless Combustion-Driven Furnace for
Materials Research in Microgravity
Technical Abstract (Limit 200 words)
The limits of electrical power available for furnaces
in space-based materials science experiments
severely restricts the maximum attainable
temperatures and the size of the processed
samples. The overall energy density stored in
chemical fuels is several orders of magnitude
greater than electrical batteries or fuel cells.
Conventional fuels, however, cannot be used in
space because of the hazard caused by the
generation of large quantities of hot gaseous
products. A novel concept for heating elements
utilizing gasless combustion of compacted powders
will allow very high temperatures (T > 3000 K) and
high energy densities for use in materials
processing. Furnaces using these heating elements
will be extremely simple and economical, and due to
the wide variety of the reactants available they can
be tailored to the specific needs of a particular
experiment (maximum temperature, duration). The
feasibility of the concept will be demonstrated by
assembling and testing gasless combustion-driven
heating elements that will provide short-duration
peak temperatures in the range of 2500-3000 K or
long-duration stable temperatures in the range of
1000-1500 K. Phase II research will target higher
temperatures (3000-4000 K), and a variety of
combustion-driven heating elements will be
designed for microgravity materials science
applications.
Potential Commercial Applications (Limit 200 words)
Gasless combustion-driven heating elements will
supplement or replace existing furnaces for
materials processing in space. These elements will
be especially useful for applications which require
short-duration high-peak temperatures, in sounding
rockets and satellites where the available electrical
power comes from batteries, and in trial
experiments where designing a permanent
specialized furnace is not economically feasible.
Spin-off of the work may also lead to the
development of heating cartridges for geological
analysis in the field (analysis for dissolved gases),
safe heating elements for canned foods, etc.

Project Title:
Apparatus and procedures for
microgravity synthesis of photonic
crystals
Technical Abstract (Limit 200 words)
The innovation proposed comprises a system which
will support the first ever synthesis of a mesoscopic
crystal in a microgravity environment by external
illumination. This organization of microparticles will
be effected in an evacuated cell by
counter-propagating beams generated by a compact
laser. The resulting structure will have lattice
dimensions directly determined by the incident
field. With the apparatus to be developed for
microgravity operation, the particles will be
practically motionless unless disturbed directly or
through electromagnetic force. This will make the
flux intensity requirement for self-organization
considerably less than the necessary intensity on
earth, which must overcome convection forces.
Phase I will entail an investigation which will result
in an in-depth expertise in the system to be
developed. The investigation will deal with
microparticles in a fluid suspension to compensate
for gravity. Phase II will involve the design and
prototyping of a unit that can serve in orbiting
microgravity experiments.
Potential Commercial Applications (Limit 200 words)
Commercialization can be implemented for
spaceborne applications. The basic nature of the
requirements for the desired effects are easily
translated into a low-cost system. The capabilities
of such a system will fill the needs of missions both
in space and on the ground. Ordered phases of
materials are extremely valuable in electronics,
optics and acoustics. In electronics: solar cells and
other photovoltaics will operate with dramatically
increased efficiency due to the emission
modification of the periodic structure imposed. In
optics: frequency-agile filters can be formed with
the particles in a fluid or vacuum host, due to the
wavelength dependency of the lattice constant.
Acoustical filters can be effected as well. Scaled-up
versions of this system can foreseeably make
possible the management of debris. Thus, as space
missions become more cost-contained, the stable
environment for binary media (particle
distributions) provided by this system will be
available to and utilized by an increasing number of
government and industrial customers: aerospace
agencies, communication and surveillance entities,
scientific research companies alike, will have a
need for a system with the capabilities described,
and the means to attain this system will be within
reach.

Project Title:
Applying X-ray Topography &
Diffractometry to improve Protein
Crystal Growth
Technical Abstract (Limit 200 words)
The proposed innovation is to develop a process
that is sufficiently non-destructive to detect and
analyze protein crystal defects and still permit a
complete conventional diffraction analysis. By
providing a quantitative means to evaluate protein
crystals it will be possible to gain insights into how
to improve their quality. By this process,
experimental and theoretical research in utilizing
the influence of microgravity in protein crystal
growth can be advanced.
The project is mainly concerned with the
microscopic technique called X-ray topography. An
understanding of the defect structures formed in
macromolecular crystals is important if growth
conditions are to be optimized. To a large extent the
success of the semiconductor industry in growing
large, defect free crystals of silicon and germanium
is due to efforts similar to the effort we are
proposing.
While X-ray diffraction is an inherently destructive
process for many protein crystals and in time will
destroy a macromolecular crystal, the process that
will be developed during this research is expected
to be sufficiently non-destructive that after the
topographic analysis it should be possible to
perform a complete conventional diffraction
analysis, determine the structure of the
macromolecule, and evaluate the quality of the
structural parameters which result.
Potential Commercial Applications (Limit 200 words)
Once fully developed and demonstrated this
process will be a vital tool in growing crystals that
can yield high resolution structural data for
structure-based drug design and for government,
industry and university macromolecular
researchers. To those performing protein crystal
growth on the shuttle and Space Station it will
enable the crystal growing process for the species
being studied to be optimized on the ground before
using these costly and limited resources.

Project Title: Non-Contact Furnace and Quencher for Microgravity Environments
Technical Abstract (Limit 200 words)
This research proposal will investigate the feasibility of developing a non-nontact furnace capable of maintaining the position and shape of a sample in microgravity. Our innovation involves the supply of a quenching or heating inert fluid without disturbing liquid or solid phases in microgravity.
The ability to transport samples will also be assessed, and thermal fluxes and pressure gradients will be logged and analyzed for feasibility. It is anticipated that a compact and non contaminating materials processing chamber can be demonstrated feasible through an appropriate investigation under surface gravity conditions.
Potential Commercial Applications (Limit 200 words)
Commercial applications for our innovation could relate to improving the performance of convection furnaces. Non contaminating processing and transport of solid phases under gravity could also be developed. Other applications as heating and quenching relating to thermal management of electronics and materials could be developed. Furnaces with selective surface temperatures and slow cooling rates could also be developed for specialized materials processing.

Project Title:
Tunable UV Light Source for
Quantitative Microgravity Combustion
Diagnostics
Technical Abstract (Limit 200 words)
Combustion studies in microgravity are critical to
ensuring the safety of personnel onboard space
craft as well as for improving our knowledge of
combustion phenomena. Under microgravity
conditions, flame ignition, propagation and
extinction become simplified due to the lack of
buoyancy. Quantitative monitoring of combustion
radicals, which control combustion kinetics although
present in trace quantities, is critical to
understanding of combustion and provides tests for
flame modeling. Many currently available
laboratory-based combustion diagnostics cannot be
adapted for microgravity experiments due to unique
space and power constraints. We propose
developing a near-UV laser source for quantitative
combustion radical diagnostics. The instrument will
measure absolute concentration distributions in
laminar and turbulent flames and will be compatible
with NASA Lewis drop tower rigs. Our approach
uses nonlinear upconversion of diode laser light to
measure simultaneously line-of-sight optical
absorbance and laser induced fluorescence images.
We target quantitative monitoring of CH and C2
radicals with 10 Hz (or better) time resolution per
two-dimensional LIF image. With the continued
development of high power diode lasers especially
at visible wavelengths, we envision this technique to
be readily extended to deeper UV wavelengths to
access other species including OH.
Potential Commercial Applications (Limit 200 words)
The proposed technology could be used as a new
combustion diagnostic tool in wind tunnel
combustion facilities, development of new
generations of rocket and jet engines, and turbine
development. In environmental monitoring
applications, many important trace molecular and
atomic species can be probed by accessing strong
electronic transitions using tunable UV and blue
radiation generated by diode laser up conversion.
Such applications include continuous emissions
monitoring of stationary power plants and municipal
incinerators, and perimeter monitoring of chemical
plants and oil refineries.

Project Title:
Fast Infrared Linear Miniature
Spectrometer
Technical Abstract (Limit 200 words)
This Small Business Innovation Research Phase I
project involves a feasibility study for a Fast
Infrared Linear Miniature Spectrometer (FILMS)
system for transient, simultaneous measurements
of carbon dioxide and water vapor concentrations,
soot volume fractions and temperatures in reacting
flows. Such measurements will lead to improved
understanding of the structure of turbulent and
laminar flames. Emission spectroscopy has been
used previously in laboratories to obtain
information on carbon dioxide concentrations, soot
volume fractions and temperatures in luminous
flames. However, a commercial instrument that can
reliably provide simultaneous gas concentration,
soot volume fraction and temperature
measurements at a high data rate
is not available.
The stand-alone FILMS system that will be
evaluated using a flame spread experiment at the
Japanese Microgravity Research Facility, which is
part of an ongoing NASA project to understand
ignition and the transition to flame spread of solid
fuels. The proposed FILMS will be the first
instrument, capable of obtaining the infrared
spectrum from 2500 to 5000 nm, resolved to 15 nm,
at 500 Hz.
Potential Commercial Applications (Limit 200 words)
Continuous monitoring of the gas species
concentrations, soot volume fractions and
temperatures is useful in all industries that utilize
hydrocarbon fuels as an energy source. The major
motiviating factor that drives development in
continuous monitoring equipment is the ability to
control the combustion process, both to achieve
greater efficiency and lower pollutant emissions.The potential market for continuous monitoring
equipment includes such diverse industries as fire
protection engineering, waste processing, gas
turbine combustors, power plants, powder metal
processing and chemical manufacturing.
For utilizing either species concentrations or
temperatures as control variables, information on
these is required at a very fast rate. The proposed
FILMS is the first spectrometer that is capable of
obtaining the full infrared spectrum from 2500 nm
to 5000 nm at 500 Hz. This is an essential step for
building process control systems. Therfore, the
commercial potential of the FILMS will increase in
the future.

Project Title Moisture and Oxygen Content Sensor
Suite for Nutrient Delivery Systems
Technical Abstract
This project will develop a small, low power instrumentation package which includes a two
part sensor suite: 1) sensor for monitoring profiles of moisture content, and 2) sensor to
detect O2 concentration in porous substrate nutrient and water delivery systems designed to
support plant growth in space. Long-term plant growth experiments aboard the Mir Orbital
Station have demonstrated that management of water and O2 in porous substrates is
substantially more difficult than in similar systems on earth. The instrument package will
consist of several pairs of moisture-oxygen sensors used to measure concentration profiles
simultaneously. The substrate moisture content sensor will use the thermal pulse method,
which detects changes in thermal conductivity as the substrate moisture content changes.
Significant innovations exist in the concept and design of each sensor as well as the
integration of the sensor into a usable electronics module with calibrated control.
Innovative improvements in moisture sensor construction, reliability, and improved sensor
design will allow calibration transfer from earth to microgravity. The companion O2
concentration sensor will monitor O2 in close proximity to the moisture content sensor to
allow the two profiles to be compared simultaneously. The innovative design of the O2
sensor includes features permitting the miniaturization of an existing commercial sensor
core to provide safe use in wet, O2 diffusion limited
environments.
Potential Commercial Applications
The moisture content and wet oxygen sensors will be important additions to advanced plant
nutrient system maintenance and control for space and ground applications. Near-term space
applications include the Biomass Production System and the Plant Research Unit. These
Sensors could become standard sensor additions to commercial growth chambers, be used in
all types of commercial growth systems where monitoring of appropriate moisture content and
aeration are important. The market is significant, especially in ornamental and more
expensive plant materials. Also markets exist for
commercial maintenance plantscapes.

Project Title:
Mars Aromatic Hydrocarbon and
Olefin Synthesis System
Technical Abstract (Limit 200 words)
The Mars Aromatic Hydrocarbon and Olefin
Synthesis System (MAHOSS) is a device for
producing low hydrogen to carbon (H/C) ratio
hydrocarbons on Mars with minimal power
requirements. It works by combining the CO and
hydrogen output of a RWGS reactor over a
Fischer-Tropsch catalyst to prepare paraffinic
hydrocarbons. These hydrocarbons are thermally
cracked to produce compounds such as ethylene,
propylene, toluene and acetylene. Its primary
advantage is the production of fuel hydrocarbons
that are low in hydrogen content relative to
normally considered fuels, such as methane. This
reduces the amount of liquid hydrogen that must be
imported or the size and power requirements of an
in situ hydrogen recovery unit by a factor of two for
ethylene and propylene, or a factor of four for
toluene and acetylene. The other advantage of the
MAHOSS is the generation of important chemical
feedstocks for plastics production. These uses
make the MAHOSS an attractive concept for early
robotic and manned missions and a critical
technology for development of a permanently
staffed Mars base. Despite the importance of these
compounds, to date there has been no experimental
work done on building an apparatus for in situ
Martian production of aromatic hydrocarbons and
olefins.
Potential Commercial Applications (Limit 200 words)
The potential commercial applications of a
combined RWGS/Fischer-Tropsch reactor are
numerous, particularly with the current
international interest in reducing CO2 emissions.
The RWGS can use a carbon dioxide feed from a
power plant or other source and can create syngas.
The Fischer-Tropsch reactor can reform the syngas
into liquid fuels for automotive or chemical use.
This project will be the first demonstration of an
end-to-end CO2 abatement system that produces
useful products.

Project Title:
Atmospheric Water Vapor Adsorption
for Mars In Situ Resource Utilization
Technical Abstract (Limit 200 words)
The innovation addressed in this proposal is a
method for extracting water vapor from the
atmosphere of Mars in an efficient, lightweight, and
reliable manner. Through the use of molecular
sieve technology, the Water Vapor Ad-sorption
Reactor (WAVAR) would provide a dependable
source of water to future exploration missions from
sources indigenous to the red planet. This water can
be used as feedstock for propellant production, for
direct human con-sumption, or as the basis for a
multitude of industrial, agricultural and biological
processes. Using locally available materials at the
site of an interplanetary misson is known as in situ
resource utilization (ISRU). Missions employing
ISRU techniques can attain dramatic cost savings,
while improving mission robustness, by reducing the
amount of raw materials that have to be transported
from Earth. The most important of these materials
is water. The WAVAR would meet this need,
providing a crucial technology for future missions.
The effort described in this pro-posal would
positively impact NASA¹s Mars Surveyor,
Planetary Science and Human Exploration and
Development of Space (HEDS) programs by
enabling the development and commercialization of
low cost, high performance WAVAR technology.
Potential Commercial Applications (Limit 200 words)
The innovation described in this proposal would
provide a reliable, low cost and high performance
method for extracting water from the Martian
atmosphere. Incorporating the Water Vapor
Adsorption Reactor (WAVAR) into future Mars
exploration missions would provide substantial
increases in crew safety and operational flexibility
while reducing cost, risk, and Earth- and
Mars-launch mass. By providing self-sufficiency
and reducing risk, the WAVAR would enable
commercial and industrial development of Mars,
thereby expanding human presence in the solar
sys-tem. Follow-on commercial oportunities exist in
a wide variety of markets where separation of fluid
species is required.

Project Title: Oxygen Generation System Using Carbon Dioxide
Technical Abstract (Limit 200 words)
NexTech Materials, Ltd. and its subcontractor (LoTEC, Inc.) will develop a ceramic electrochemical system for extracting oxygen from the carbon dioxide rich atmosphere of Mars. The key innovations leading to this development are the identification of novel ceramic electrolytes and electrode materials which provide reduced operating temperatures and the incorporation of these materials into a novel monolithic electrochemical cell design. In Phase I, novel electrolyte materials will be evaluated for separating oxygen and carbon dioxide at temperatures between 600 and 800°C. Cermet electrode materials providing efficient catalytic performance at these low temperatures will be developed using ceramic-based catalysis-enhancing additives. A preliminary design of the electrochemical cell will be conducted, and a specifications of balance-of-plant components will be generated. It is expected that the combination of the new materials and the novel design will provide a means to extract oxygen in a system that is smaller, less energy intensive, more reliable, and less expensive than currently available technology allows.
Potential Commercial Applications (Limit 200 words)
Successful development of this technology will lead to numerous commercial and military applications related to oxygen generation, solid oxide fuel cells, and ceramic membrane reactors. Examples of military applications include oxygen supplies for military aircraft, medivacs, and mobile hospitals. Commercial applications include industrial oxygen production, semiconductor manufacturing, home health care, and commercial aircraft.

Project Title: Reusable, Reagentless Biosensor for Monitoring of Spacecraft/habitat Environment
Technical Abstract (Limit 200 words)
Systems & Processes Engineering Corporation (SPEC), in collaboration with Professor Carl Batt of Cornell University, proposes to develop a miniaturized, reusable and reagentless biosensor for monitoring of the chemical and microbial quality of the spacecraft/habitat environment. The proposed biosensor measures the fluorescence lifetime of a strategically placed fluorophore near the receptor binding pocket to monitor ligand binding to the receptor. The proximity of the ligand to the fluorophore results in a fluorescence lifetime shift which can be accurately detected and measured by SPEC's proprietary frequency domain lifetime technology. This innovative concept combines the sensitivity and specificity of biological ligand-receptor systems such as antibody-antigen or drug-receptor interactions with the reliability, accuracy and discrimination of fluorescence lifetime measurements. SPEC will utilize its experience in building flight-worthy systems to develop a compact, lightweight, low-power and rugged instrument for space applications. Dr. Batt will direct the molecular biology development effort. For the Phase I, the model biological receptor-ligand system b-lactoglobulin and its ligand retinol will be used to demonstrate proof-of-concept. SPEC will construct a breadboard system for lifetime measurements of the model receptor-ligand system. In the Phase II program, a prototype system will be constructed and delivered to NASA for field testing.
Potential Commercial Applications (Limit 200 words)
The development of a compact, low-cost receptor-ligand diagnostic instrument capable of providing rapid results has significant commercial applications as home diagnostic devices, medical research tools, food processing monitors, clinical instruments and environmental detectors as well as for NASA and the Department of Defense. Biological receptors can provide high specificity in the detection of chemicals, pathogens, and environmentally hazardous biological organisms. The use of lifetime fluorometry results in a commercially valuable reusable and reagentless diagnostic device.

Project Title: Miniature, Semiconductor, Sharp Bandpass Detector for Biological Fluorescence Detection
Technical Abstract (Limit 200 words)
In this Phase I SBIR project wide band-gap semiconductor p-i-n photodiodes with sharp bandpass responsivity will be developed for use in ultraviolet fluorescence detection of biological contamination of high purity water systems. AlxGa1-xN, grown by molecular beam epitaxy (MBE) will be used to fabricate photodiodes having high quantum efficiency spectral response in the ultraviolet. The innovation in this proposal is to combine a short wavelength absorbing, electrically non-active overlayer with the electrically active p-i-n structure photodiode to produce a sharp bandpass photodetector. Such a device will have near quantum efficiency response inside the bandpass and ~105 rejection of radiation outside the bandpass. The sensor will allow replacement of
fragile and power hungry photomultiplier tubes currently used for fluorescence detection. The all semiconductor, ultraviolet sensitive photodiode for biological fluorescence detection will be compact, rugged, and low power consuming, which are important attributes for sensors on manned space missions. For the Phase I project, the essential amino acids tryptophan and tyrosine will be evaluated as model systems for biological detection. Tryptophan and tyrosine are present in nearly all proteins, and their detection can be used as a warning of biological contamination. Both of these amino acids can be excited by the 254 nm line of mercury discharge lamps commonly used for sterilization of high purity water systems.
Potential Commercial Applications (Limit 200 words)
Miniature semiconductor photodiodes for biological fluorescence detection will have applications in water quality assurance testing, in-situ monitoring of bio-reactions, and in bio-analysis.

Project Title: Optical Sensor for Multi-Species Air Quality Monitoring
Technical Abstract (Limit 200 words)
Rapid measurements of trace air contaminants are required for the maintenance of crew safety in spacecraft and human-rated ground test facilities. Currently, these measurements are carried out using a variety of gas-specific instruments. Separate instruments must be installed for each target gas (occupying valuable space) frequent calibration is needed (increasing ground test costs), and response times are slow. Our innovation is a rugged mid-77infrared spectrometer, based on difference-frequency mixing of two diode lasers, which will detect multiple trace gases using absorption spectroscopy. The device will have a wide wavelength tuning range, allowing the detection of multiple species by a single instrument. Concentrations will be measured directly and in real time, eliminating the need for repeated calibration and allowing rapid remedial action. Compact diode lasers will be used in this instrument, thus making it lightweight and small enough for space flight. During Phase I we will build a mid-infrared laser source, demonstrate wide tunability, and make simultaneous concentration measurements of two trace air contaminants such as formaldehyde and methane. In Phase II we will produce and deliver a portable laser spectrometer incorporating our innovations for use in NASA ground test facilities for life support systems.
Potential Commercial Applications (Limit 200 words)
A compact, affordable infrared spectrometer for the quantitative remote sensing of trace gasses would be attractive to industries trying to keep up with tightening EPA regulations, as well as to those trying to implement stricter controls over manufacturing processes.

be treated is the only reactant, eliminating the need
for expendable biocides. Possible applications of
the ozone generator include: wastewater treatment,
production and maintenance of potable water, and
sterilization of potable-water systems.
The objectives of the proposed program are to
develop the anode catalyst and anode electrode
structure and demonstrate performance and
stability of this structure. The program will
culminate in demonstration of a breadboard
prototype ozone generator and development of a
system design model.
Potential Commercial Applications (Limit 200 words)
Ozone is a powerful disinfectant, with wide potential
applications for water treatment and sterilization.
Due to the compact size, low cost and ease of use of
the proposed electrochemical ozone generator,
there are a myriad of potential commercial
applications in the dental, medical, pharmaceutical
and food industries for this device. Applications
include sterilizing dental units and dialyzers and
general hospital and laboratory disinfection.
Treatment of drinking and waste waters in homes
and public and private utilities is another potential
application.

A Functional Visual Assessment Test For
Human Health Maintenance And
Countermeasures
Technical Abstract (Limit 200 words)
We will develop a portable computer-based test of
functional visual acuity that can be applied to
conditions involving whole-body perturbation that
are common in aerospace operations and in the
activities of daily living. Our visual-acuity test is
innovative in that (a) it can be applied while the
observer is walking, in a vehicle cockpit, or in
standardized optometric conditions, (b) it is
commensurate with international standards for
optometric procedures and diagnostic information,
and (c) it allows for differentiation between
ophthalmic and neuromuscular causes of impaired
acuity. These unique characteristics of our
innovative test are relevant to Topic 10.03,
On-Board Human Health Maintenance and
Countermeasures, because they can enhance
"understanding of the effects of microgravity and
other components of the space environment on the
physiological systems of the body" by allowing for
standardizable quantification of visual acuity and
coordination of the associated neuromuscular
systems through "novel software methods for
documentation, storage, retrieval, analysis and
diagnosis of crew health." Moreover, by enhancing
diagnostic differentiation and generality, our
innovative test can support the development of
"countermeasures against deleterious changes in
body systems in flight or upon return to the ground
[including]... post-flight reduction in neuromuscular
coordination."
Potential Commercial Applications (Limit 200 words)
Aerospace medicine.
Research & design of displays & controls for

Novel RF Coils for MRI/MRS of the
Human Bone and Muscle
Technical Abstract (Limit 200 words)
Magnetic resonance imaging (MRI) is an elegant
modality for performing volumetric measurements
and obtaining metabolic information of the human
bone and muscle, in-vivo, non-invasively without the
use of ionizing radiation. A major aim of this project
is to provide novel RF coil hardware to support the
on-going pre/post space flight protocols and bed
rest studies performed on astronauts/cosmonauts at
the Baylor College of Medicine. The proposed
SBIR research is relevant to NASA's subtopic
10.03 On-Board Human Health Maintenance and
Countermeasures. In Phase I, a homogeneous, RF
coil volume array with a further 30-40%
improvement in S/N for high-resolution calcaneus
imaging will be developed at 1.5T. Phantom
measurements (S/N, uniformity) will be made and
compared to existing coils. Phase II will involve
extensive volunteer evaluations to assess
trabecular bone quality. We will extend our RF coil
technology and build a custom detector array for
high-resolution imaging of the neck muscles.
Furthermore, we intend to build a hybrid
quadrature, dual-tuned 31P-1H volume resonator
for 1H anatomical imaging as well as obtaining 31P
metabolite information from the entire human calf
muscle. All three coils will be extensively tested
with phantoms and volunteers first.
Potential Commercial Applications (Limit 200 words)
Clinical applications include non-ionizing,
non-invasive and a cost effective approach toward
diagnosis of arthritis and musculoskeletal diseases
of the knee, wrist and hand, foot and ankle when
compared to the invasive arthrography. The
proposed R&D will provide improvements to MR
phased array and dual-tuned RF coil technologies
including sequence and technique optimizations. If
clinical value is demonstrated, MR systems based
on this technology will find wide spread applications
in MR imaging and spectroscopy of the joints and
the human musculoskeletal system.

Project Title: Non-Invasive Method for Assessment of Human Fine Motor Control
Technical Abstract (Limit 200 words)
VeriFax proposes to develop a biometric instrument to monitor human fine motor control. Through non-invasive action of signing a signature or reproducing cursive symbols, the device can measure and record an individual's motor skill characteristics. The designers have focused on how a person writes as opposed to how writing looks. Any two signals which represent repeated realization of the same handwriting samples are compared with use of the VeriFax's proprietary technology in order to provide characteristics of stability, smoothness, and synchronization of the handwriting movements. The method uses a new approach for Correlation Function Analysis applied to behavioral signals, such as handwriting
dynamics.
A prototype unit based on digitized grid non-instrumented pen configuration will be built and tested. An experiment on the effect of environmentally induced variations in stress level will be performed. The experimental study will determine if the level of stress experienced by college students throughout an academic semester is correlated with changes in handwriting dynamics. resumably, as stress increases, handwriting motor skills should deteriorate.
The device might be used as an early warning tool bringing attention to causes that may result in neurological impediment, or risks to health, or performance ability. NASA applications include:
- Early detection of the cognitive and motor skill decline as a result of low concentrations of inhaled toxic compounds, oxygen depletion, or sustained and intense stress. - Assessment of countermeasures developed to prevent deleterious changes in neuromuscular coordination and loss of muscle mass.
High accuracy, simplicity, portability, and low power consumption of the device will make it a valuable tool for monitoring well-being of astronauts in long-duration space missions.
Potential Commercial Applications (Limit 200 words)
The instrument has great potential for the following commercial applications:
- Assessment of motor skill deterioration as a result of environmentally induced stress will be used for 1) design of methods for identification of high risk stress level; 2) development of stress management programs at schools and other settings; 3) optimal scheduling of continuous hours and breaks on production assembly lines, or other demanding work environments.
- Assessment of motor skill impairment caused by decline in muscle mass will be used for design and monitoring of strength training programs for older adults to increase their activities and the quality of life.
- Non-intrusive screening of professionals for alcohol/drug impairment where public safety is a concern; further research of mechanisms of intoxication and identification of individual high risk factors; monitoring people with alcohol/drug abuse problems going through treatment programs.

Project Title:
Blackbody Photoreactor for
Space-Based Water Treatment
Technical Abstract (Limit 200 words)
While many forms of chemical waste are easy to
destroy via simple oxidation processes, others are
not. These include propellants, explosives, dyes,
halocarbons, and wastes tainted with heavy metals.
However, these materials, as well as simple
organics, are amenable to treatment via advanced
oxidation processes (AOPs) such as ultraviolet
(UV)/peroxide treatment, UV/ozone treatment, the
use of Fenton's reagent, and titanium dioxide
(TiO2)-assisted photocatalysis. While all AOPs
operate by generating OH_ radicals, TiO2-assisted
photocatalysis has the greatest promise for low-cost
operation due to the fact that it requires only air (or
water) and sunlight. The primary drawback to
TiO2-assisted photocatalysis reactors is the low
solar absorptivity of TiO2. Only a small fraction
(1-2%) of the visible light is absorbed, while the
rest is transmitted and lost. Such low absorptivities
yield low oxidation rates and are an
impediment to the commercialization of this
technology. In this Phase I project, Ultramet
proposes to design and fabricate a novel reactor
that will yield order of magnitude increases in the
removal rate. This will be achieved by fabricating a
blackbody cavity of the catalyst material, which will
result in virtually all of the incident radiation being
absorbed by the catalyst. A second innovation will
be the use of a TiO2 aerofoam as the catalyst. This
high surface area, high absorptivity, low pressure
drop material can be used as a fixed catalyst bed,
eliminating the need to separate the catalyst from
the effluent stream. Techniques such as doping the
TiO2 with other catalytic oxides or noble metal
clusters and using charge injection from organic
dyes will also be investigated.
Potential Commercial Applications (Limit 200 words)
The applications for an efficient photocatalyzed
reactor in both the government and private sectors
are numerous. With over 65 metric tons of
hazardous solvent waste and 60 metric tons of other
chemical wastes being generated by the chemical
process industry each year, the demand for a
cost-effective, high-efficiency treatment process is
immense. Military stockpiles are also in need of
remediation. And although the U.S. is the leading
producer of waste chemicals, other industrial
countries are also in need of a low-cost remediation
technology.

Project Title: Sol-Gel Glass Holographic Light Shaping Diffusers
Technical Abstract (Limit 200 words)
Physical Optics Corporation (POC), R&D Division proposes to develop an innovative Glass Light Shaping Diffuser (GLSD) technology to enhance light transmission and distribution efficiency in controlled crop/plant production facilities. High thermal damage threshold (?1000°) and high transparency ((?90%) in the UV-vis-NIR make this material ideal for use in high-temperature and high-illumination environments. GLSD will increase the photosynthetic active radiation (PAR) efficiency of plants in controlled growth chambers by homogenizing and shaping the light distribution from high intensity discharge sodium lamps and/or fluorescent bulbs without loss of transmission efficiency. Specific objectives of the proposed project include: 1) Demonstrate holographic glass light shaping diffusers with high transmission and distribution efficiency, 2) Demonstrate GLSDs that diffuse light at a variety of angles (1° to 120°) and shapes (circular and elliptical), and 3) Demonstrate that GLSDs substantially enhance PAR efficiency. Design, fabrication, and testing activities carried out to achieve these objectives will ensure a smooth transition to Phase II development and Phase III commercialization.
Potential Commercial Applications (Limit 200 words)
The development of GLSDs will significantly enhance the capabilities of POC's commercially successful light shaping diffuser product line, opening broad new markets in lighting systems, projection systems, and advertising displays. Additional applications include motor vehicle and aircraft lamps, street, sport, and entertainment industry lighting, high energy laser beam homogenizers, and office lighting.

Project Title: Advanced Waste Management in Space Missions
Technical Abstract (Limit 200 words)
This NASA SBIR Phase I project is a feasibility study for treating wastes generated during space missions and producing emissions that are within the Spacecraft Maximum Allowable Concentrations (SMAC), using wet carbonization and advanced combustion technologies. EnerTech's innovative wet carbonization technology will transform heterogeneous metabolic wastes and trash components, through a moderate temperature and pressure carbonization, into a uniform and pumpable slurry, which the Energy & Environmental Research Corporations's (EER) advanced combustion technology of Hybrid Fluidized Bed Incinerator (HFBI) will combust with emissions that are within SMAC standards. The CO2 and H2O generated during conversion of the wastes can be used to support plant growth systems and provide for a closed-loop, regenerative life support system. The objective of this Phase I proposal is to determine the characteristics of the product slurry from wet carbonization experiments and an acceptable range of combustion onditions to are within SMAC standards. In Phase I, wet carbonization and advanced combustion experiments will be conducted with existing bench-scale facilities using actual metabolic wastes and trash components. It is anticipated that Phase I and Phase II research will produce a prototype unit that can be integrated into a functional life support system in Phase III.
Potential Commercial Applications (Limit 200 words)
The commercial product and technology to be developed under this Phase I and Phase II proposal is being targeted at the specific needs of NASA, the ultimate customer. The commercial product to be developed will be an integrated wet carbonization and advanced combustion unit, with associated automated control systems, capable of treating the wastes generated from a four person space ission and producing emissions that exceed SMAC standards. In addition, the small-scale unit to be developed will form the basis for much larger units that will be necessary for larger spacecraft missions (e.g. S.S. Freedom) or lanetary colonization. In addition to NASA applications, the technology to be developed has potential applications for treatment of wastes generated on-board U.S. Navy ships and other commercial vessels at sea and radioactive and hazardous wastes generated at laboratories.

Project Title: A High Performance, Gravity Insensitive, Enclosed Aeroponic System for Food Production in Space
Technical Abstract (Limit 200 words)
EnviroGen, Inc., an industry leader in aeroponic technology and rapid plant propagation techniques, has teamed with BioServe Space Technologies, a Commercial Space Center at the University of Colorado in Boulder, to develop an enclosed aeroponic nutrient delivery system, insensitive to gravity, for use in spaceflight food crop production and gravitational biology research. Other non-aeroponic enclosed plant growth technologies for use in low gravity have been and currently are being developed. However, aeroponic plant propagation dramatically increases biomass production rates at higher plant densities while reducing nutrient solution mass, plant-to-plant disease transmission, and time spent planting and harvesting, critical when weight and space are at a premium on long-term space flights. Additional advantages of the proposed aeroponic system include efficient water/micronutrient delivery (using controlled misting interval and duration), environmental parameter adjustment based on plant growth/health, and plant physiological monitoring. The team has identified innovative approaches, integrating forced convection, capillary flow, and porous plate water recovery techniques, to deal with low-gravity two-phase flow resulting from aeroponic misting. The development, testing, and qualification of such a system will serve to broaden aeroponics' commercial use in terrestrial crop production, pharmaceutical research and production, and plant biology research.
Potential Commercial Applications (Limit 200 words)
Terrestrial markets would be food crop production companies as well as pharmaceutical companies that require technology to rapidly regenerate plant material for metabolic extraction of pharmaceutical products. Other flora that could be grown include a wide variety of trees, shrubs and ornamental horticultural crops. A tremendous amount of research and development to be carried for optimizing the specific environmental parameters for a given plant species in enclosed environments. Aeroponic environmental parameters can be modified and adjusted to greatly influence growth for a specific crop; this data model can be stored in the aeroponic system's computer. Once this data model is obtained it can be used to optimize conditions to achieve even higher yields and/or increase biomass. Given the hundreds of plant species that can be grown in an aeroponic system data modeling would be valuable for reproducibly maximizing yields and crop turn-around times. Utilizing an enclosed aeroponic system as method and apparatus in conjunction with vegetative propagation could reduce the reliance on seeds as well as eliminate the need for extensive tissue culture procedures and hardware. This would be an invaluable tool for low gravity and terrestrial crop expansion. The market optional for this technology is vast.

Project Title: The Manufacture of Ethylene and Other Useful Products in Life Support Systems for Manned Spacecraft and Planetary Bases
Technical Abstract (Limit 200 words)
Our program is based on these premises: (1) Ethylene and other useful products, e.g., polyethylene and ethanol, can be manufactured from metabolic wastes, e.g., carbon dioxide and water, as an adjunct to Life Support Systems (LSS) required in manned spacecraft and planetary bases, e.g., Moon and Mars; (2) These products are best manufactured using inorganic processes based on chemical engineering principles, and (3) These processes make use of the major components of metabolic waste, carbon, hydrogen, and oxygen. Our program satisfies the requirements of Subtopic 10.04 Spacecraft Life Support Infrastructure:
"Advanced life support systems are essential for the success of future human planetary exploration." It focuses on (1) Direct Catalytic Reduction of Carbon Dioxide and (2) Catalytic Reforming of Methane to produce Ethylene in conversions greater than 95%. Benefits are: (1) The conversion of metabolic wastes to useful products, including potential foodstuffs, (2) Weight savings which may result from reduced on-board foodstuff requirements; (3) Manufacture of useful products based on engineering principles, not life processes, e.g., plants, and (4) reduced resupply from Earth.
Potential Commercial Applications (Limit 200 words)
Conversion of carbon oxides to hydrocarbons and carbohydrates using catalytic processes shall have very important commercial benefits in the future as carbon-based fuels, i.e., petroleum and natural gas, are exhausted. The use of low-grade coals to synthesize such products as methane and ethanol will form the basis for a new, important chemical process industry in the United States which has vast coal reserves.

On Demand Electrochemical Production
of Reagents to Minimize Resupply of
Expendables.
Technical Abstract (Limit 200 words)
Electrochemical methods are proposed for the
on-demand generation of strong
acids (HCl, H2SO4), strong bases (KOH, NaOH),
and oxidants (KHSO5, Na2S2O8). Acids,
bases, and oxidants are required for the operation
of a variety of present and future
components of regenerative life support systems.
They will also be needed for use in
analytical instruments, and as reagents in
experiments and commercial processes which
exploit the unique aspects of the microgravity
environment. Because these chemicals are
highly reactive, their storage and use aboard
spacecraft must satisfy very stringent
containment requirements. Their use also imposes
a significant resupply burden.
UMPQUA Research Company proposes the
development of a microgravity and
hypogravity compatible process for the production
of acids and bases from the
corresponding salt by electrodialytic water splitting.
Strong oxidants such as oxone and
persulfate will be produced by the electro-oxidation
of sulfuric acid. The ability to
produce these chemicals, when needed, offers many
advantages with regard to
operational flexibility, storage, containment, safety,
and resupply logistics, and will be
particularly beneficial in support of future long
duration manned missions in space.
Potential Commercial Applications (Limit 200 words)
The primary commercial application for the
on-demand electrochemical
generation of acids, bases, and oxidants will be as
Flight Hardware purchased by NASA,
or by an aerospace contracting firm on behalf of
NASA, to provide enhanced capability
with minimum resupply requirements for component
processes in future advanced life
support (ALS) systems needed for long duration
manned missions in space, such as a
space station retrofit, a permanently inhabited
Lunar base, or a manned mission to Mars.
The technology may also be employed in support of
earth based systems which are used
in remote locations such as Antarctica, where
resupply of chemicals is difficult and
costly.

Project Title: System for Removal of the Oxides of Nitrogen and Sulfur from Incinerator Effluents
Technical Abstract (Limit 200 words)
Long duration missions will use plant growth to produce food and oxygen. However, plant-based systems produce large amounts of waste biomass, much of which will ultimately be burned. In addition to producing CO2 and H2O, this process also makes a variety of harmful by-products including particulates, CO, hydrocarbons, SO2 and NOx. Current systems for removing acid gases such as SO2 and NOx use a combination of selective catalytic reduction (of NO) and absorption on copper oxide (a low capacity SO2 sorbent). Because this method only reduces NOx by 50%, a carbon bed is needed to complete the process, leading to large expendable consumption in addition to the use and emission of ammonia, a hazardous and toxic chemical. TDA Research Inc. proposes to remove these acid gases by oxidizing the NO to NO2, absorbing SO2 and NO2 in water, neutralizing the acids, and concentrating the resulting salts into a small amount of olution. The result is a safer, more effective process for acid gas control and a significant reduction in consumable materials required.
Potential Commercial Applications (Limit 200 words)
The successful demonstration of NOx control technology would find immediate application in many areas, including control of emissions from gas turbine power generators and nitric acid plants.

Low Temperature Lightoff, Lightweight
Catalytic Oxidation Reactor for Life
Support Systems
Technical Abstract (Limit 200 words)
A new class of catalyst technology for catalytic
oxidation is developed based on ultra-short channel
metal monolith(USCMM)substrate with a high
specific surface area (SSA) slip coat. The
technology provides smaller, lighter, more energy
efficient catalytic systems than are possible with
conventional monolith or pellet substrates.
Catalytic oxidation is highly effective in destroying
a wide range of contaminants in applications
ranging from industrial sources such as solvents to
trace airborne contaminants in life support systems.
The technology builds upon Precision Combustion's
previous success in developing an electrically
heated catalytic oxidizer for NASA's Trace
Contaminant Control Subassembly (TCCS) that was
based on a low SSA USCMM catalyst system. This
new catalyst technology combines the excellent
transport properties of the USCMM (low thermal
inertia and excellent mass transfer) with the lower
temperature activity of the high SSA support.
Potential Commercial Applications (Limit 200 words)
The technology can provide lower overall launch
and resupply costs and lower power requirements
when integrated into NASA life support systems for
the Trace Contaminant Control
Subassembly(TCCS), catalytic oxidation for waste
water reclamation, or treatment of exhaust gas
from solids waste incineration. There are
substantial spinoff commercial opportunities for this
technology, primarily for automotive catalytic
converters, air cleaners, clean burners, and
chemical reactors.

ICAT Enhanced Multimedia-Based
Training
Technical Abstract (Limit 200 words)
LinCom Corporation is proposing an innovative
approach to improving training for ground support
and mission operation personnel by embedding the
capabilities of NASA's award winning Intelligent
Computer Aided Training (ICAT) software into
mainstream commercial Computer Based Training
(CBT) tools. NASA has invested over ten years of
research and development into ICAT technology.
ICAT reflects state-of-the-art technology for
developing high-fidelity interactive training
systems. However, this technology has primarily
been confined to federal laboratories, universities,
and a few corporations. Traditional Computer
Based Training (CBT) software is now beginning to
require extensive high-end features beyond the
standard integration of sound, video, and animation.
Current corporate expectations include advanced
student interactions, sophisticated user tracking,
and extensive navigation features similar to those
already available in ICAT. The innovation of
integrating ICAT, whose focus is on "learning by
doing", with CBT would be a natural fit and would
satisfy this demand. Since the use of
commercial-off-the-shelf CBT authoring tools for
training in mission operations at NASA is an
established and growing practice, intelligent
tutoring that would encompass student performance
throughout a CBT training module would
dramatically increase the power of the training
Potential Commercial Applications (Limit 200 words)
Anyone who develops courseware using the most
popular CBT authoring systems - such as
Authorware, Toolbook, Quest, IconAuthor, and
Director - is a potential customer for the ICAT
CBT Plug-In. This includes courseware developers
from industry, government, education or in CBT
consulting. These developers will typically maintain
a portfolio of products that expand the functionality
of their work. The ICAT CBT Plug-In will be
designed for seamless integration into any delivery
method, whether via CD-ROM, Internet, LAN or
DVD, thereby assuring the broadest possible
commercial application. A follow-on market for
upgrades, technical support and custom
development will also be created.

Project Title:
Intranet/Internet Accessible Inventory
Management System (IA-IMS) for
On-Board and Ground Based Mission
Operations
Technical Abstract (Limit 200 words)
APTEK proposes an innovative approach for
accessing real-time spacecraft and ground
operations inventory data using Java and the
Intranet/Internet. Our approach uses
object-oriented Internet technology to enable
astronauts, ground support and mission training
personnel to efficiently and accurately manage their
inventory. This is innovative in that for the first
time, inventory data will be accessible from any
computer connected to the Internet that is capable
of running a Java-aware Web browser. With
extensive security measures in place, astronauts,
ground support, and other authorized personnel
from around the world can have real-time access to
the on-board Inventory Management System (IMS)
for scientific and/or educational purposes. In
addition, hard to represent storage configurations
will be more accurately modeled using the powerful
graphics available through Internet technology. The
proposed improvement to the current IMS will
increase overall crew and ground operations
performance and productivity and reduce inventory
management costs by providing the following
specific benefits to NASA: 1) Improved distribution
and reliability of data; 2) Reduced support and
maintenance costs; 3) Reduced hardware and
networking costs; 4) Reduced learning curve for
IMS operations; 5) Improved habitability of
extended space missions; 6) Increased availability
throughout NASA and to other educational and
scientific communities.
Potential Commercial Applications (Limit 200 words)
The proposed APTEK Intranet/Internet
Accessible-Inventory Management System
(IA-IMS) innovation has significant commercial
potential for both the government and the private
sectors. For the government, the IA-IMS will
provide a software system which is accessed via the
Internet whereby all participants on a project can
have instantaneous access to the identical
inventory information associated with that project.
A key feature of the innovation proposed is the
Java software capability. The Java software allows
a central data base to reside on a central computer
and the capability to rapidly download the
information of interest to individual clients. The
initial commercial application is envisioned to be for
NASA in support of the International Space Station
(ISS) project. All foreign and domestic researchers
and mission operations personnel associated with
the ISS can access the current inventory on board
the ISS. Additional commercial activities exist
whenever multiple remote operations are concerned
with a central inventory. This is a characteristic of
virtually every large corporation, particularly those
with international operations. Military logistics and
operations are another prime example where the
APTEK IA-IMS software can produce a significant
reduction in operating costs and an increase in
efficiency. Thus the potential markets for the
IA-IMS software are huge.

Project Title:
Inflatable Structure for Mars Trans
Hab
Technical Abstract (Limit 200 words)
The shape and strength of inflatable structural
components can be closely controlled by taking
advantage of the high specific strength and stiffness
of fibers such as Kevlar and Vectran in forming the
skin for inflatable structures. Enhanced dimensional
control during inflation has been demonstrated by
selectively controlling the type and direction of the
structurally dominant fabric fibers in all material
layers. This proposal describes the use of this
demonstrated capability to select the optimum
structural fabric material for an inflatable structural
shell, select a compatible elastomeric adhesive,
perform an investigation of winding and braiding
fabrication techniques including a finite element
structural analysis of the optional configurations,
and construction of a scale model of the Trans Hab
module using the selected fabrication techniques.
Conduct of this program will result in identifying the
optimum construction method for the inflatable
toroid used in the Mars Trans Hab concept
developed by NASA Johnson Space Center (JSC).
Potential Commercial Applications (Limit 200 words)
The fabrication materials and techniques to be
identified/developed during this project are suitable
for other large inflatable structures needed for
space applications, including: expanding the space
station habitat and storage modules to
accommodate more crew members and a greater
number of experimental facilities; and potential
applications for inflatable structure concepts
suitable for both Lunar and Mars habitats.
This methodology for building inflatable structures
also has potential terrestrial uses. Large collapsible
storage vessels can be constructed using these
techniques that would be suitable for moderate
pressure storage and transport of gases and liquids
with temperatures ranging from cryogenic to 200
°F.

Project Title: Habitat Skin with Integrated Thin-Film Power Subsystem
Technical Abstract (Limit 200 words)
As Johnson Space Center and other NASA centers study long-term manned missions to the moon and Mars, one of the key enabling technologies is provision of a livable, self-sustaining habitat. However, while this habitat must represent a safe haven, it also must be practical to launch, erect, and maintain.
ITN believes that integrated systems represent an elegant, achievable means to these ends and is currently developing a number of thin-film power system technologies which could be integrated with the habitat skin to create a Multifunctional Habitat Skin. Specifically, ITN proposes herein a revolutionary integrated skin concept comprising:
Integrated Power Pack (IPP), a multilayered laminate of thin-film hotovoltaics, thin-film battery, and thin-film power management and distribution electronics
Direct integration of IPP with the habitat¹s structural skin element, whether flexible or rigid
Key advantages of our IPP concept, compared to a conventional power subsystem with separate solar array, battery, and power electronics components, include the following:
reduced launch mass, volume, and number of launches to field a given system
reduced assembly procedures; assembly of habitat also deploys the power subsystem
reduced mass of structural elements; increased mass fraction for science, consumables, fuel, or margin
Potential Commercial Applications (Limit 200 words)
The Integrated Power Pack subsystem, proposed herein for integration with Trans-Stage and Planetary Habitats, will have significant spin-off potential, including:
Tent/Shelter Power Supply: This concept is virtually identical to that proposed herein, except applied to a terrestrial system. For the military user, IPP would replace or augment diesel generators, thereby reducing fuel resupply demands, and noise and IR signatures. It can also provide critical power for civil deployments, such as ³medical missionaries². If IPP can be produced very cost-effectively, it could even be implemented on consumer products such as camping tents and trailer awnings.
Portable Electronics Power Supply: The IPP/skin concept can serve as a stand-alone power supply for many portable electronics systems. Military applications include radios, data relays, and GPS. Commercial applications include laptop computers, camcorders, and cell phones.
Unmanned Space Systems and Aerial Vehicles (UAVs): Many unmanned systems, including spacecraft, the Pathfinder UAV, and some balloons, use solar energy for primary power. IPP could replace the conventional solar cells with a complete power subsystem, providing significant, mass, volume, and payload benefits.

Project Title:
Lightweight, Low Thermal Conductivity
Cryogenic Penetrations
Technical Abstract (Limit 200 words)
Foster-Miller proposes to refine and utilize its
proprietary and patented liquid crytalline prolyemrs
(LCP) processing technology to produce low weight
and low thermal conductivity cryogen tank
penetrations such as feed lines, vent lines and
instrumentation feed throughs. Our biaxially
oriented LCPs are ideal for cryogenic applications
because of their proven compatibility with LOX,
retention of ductility and strength at cryogenic
temperatures, low permeability to gases, far lower
density than metals or composites, and
exceptionally low thermal conductivity. Our
proposed approach is expected to reduce cryogen
tnak thermal induced losses by 17-25%. This will
result in significant reductions in the cryotank
weight or major increases in strorage capacity if the
original tank weight is maintained. Such savings can
extend mission life or increase payload capacity.
Potential savings are expected to range from
$275,000 to $2,000,000 per launch/mission.
In Phase I Foster-Miller will demonstrate the
feasibility of our minimal heat transfer LCP
cryogenic tank penetrations. We will produce
tube/pipe at varying biaxial orientations and wall
thicknesses, and establish their mechanical,
thermomechanical (CTE) and thermal conductivity
properties. A cost/benefit analysis will then be used
to establish the technical and economic viability of
our LCP cryogenic tank penetration components.
Potential Commercial Applications (Limit 200 words)
Commercial applications include high strength
tubes for aerospace and astrospace structures
where zero axial CTE can provide major benefits,
accurate gauge medical tubing for endoscopic
instruments and tools, and high voltage electrical
tubing and conduit. In addition a larger scale
version of this technology may be readily applied to
advanced-high performance solid rocket motors.

Project Title:
Heat-Driven Pyroelectric Pump
Technical Abstract (Limit 200 words)
Pumps with moving parts are prone to failure and
are often subject to gravitational limitations.
Proposed is demonstration (Phase I) and
development (Phase II) of a novel heat-activated
pump using the pyroelectric effect. With materials
whose dielectric constant is a strong function of
temperature, this effect can be used for heat
engines. Direct pumping of liquids is also possible,
by heating them within the electric field. Water is
an ideal fluid for this application because the
dielectric constant changes rapidly with
temperature. Recuperation of sensible heat yields
an efficient pump with no moving parts, and staging
can be used to achieve a large pressure head. The
electric field is not consumed, so electric power
consumption for field generation is limited to
leakage losses. Heat in any form can drive the
pump. The lack of moving parts (motor,
transmission, etc.) will not only increase reliability
but will also reduce weight, especially for small
capacity pumps. The heat-driven pyroelectric pump
is proposed as an alternative to
"piezoelectric/magnetoresrictive driven pumps with
high reliability" suggested under subtopic 10.08.
Potential Commercial Applications (Limit 200 words)
If proven, this innovative pump would find use in
many applications where its special features
(heat-driven, no moving parts, maintenance free)
are desirable. Specific examples include: (1)
solution pumps on sorption refrigeration systems,
where heat is available and electric pumps add
considerably to operating costs, (2) very small flows
where motors and mechanical pumps are very
inefficient and reliability is a problem, and (3)
pumps for solar heating systems, in which case the
pump would be heat driven with pumping rate
increasing as more heat was available.

Advanced display for immersive
telepresence system
Technical Abstract (Limit 200 words)
Flogiston Corporation proposes to design and
develop an advanced display system for immersive
telepresence applications which provides full
spherical field of view, using its proprietary Bubble
Dome technology, combined with a Head Mounted
Display (HMD) to provide high resolution stereo
vision in the foveal area. Astronauts will use the
compact display system on board the Space Station
to interact with and control robotic systems such as
the Robonaut, perform inspections of external
systems using autonomous EVA robotic cameras,
and view immersive virtual and telepresenced
environments for training and communications.
Existing robots retain their current head tracked
stereoscopic cameras, while adding fixed fisheye
view cameras. The fisheye image is back projected
on to the exterior of the small dome, called a
telesphere, to provide a general field of view
without lag that engages peripheral vision, while the
stereoscopic image is displayed on the HMD for
detailed inspection. This enables the astronaut to
look around freely inside the telesphere, providing
a sense of presence that HMDs alone cannot
convey. This display significantly increases the
capabilities of humans to control robotic systems
and put their awareness at the robot's location.
Potential Commercial Applications (Limit 200 words)
The advanced display has many applications in
commercial telepresence and immersive
cyberspace applications. Flogiston is already
marketing the Flostation with its basic dome for
commercial use in the entertainment, research,
education and medical fields. Any improvements to
the display can readily be assimilated into the
Flostation and improve the image quality. The
addition of a high resolution HMD to compliment
the dome has practical applications for surgery
training, telepresence surgery, control of remotely
piloted aircraft, submersible vehicles, hazardous
area robots, and in the entertainment field. The
complete telesphere also has applications for
remote viewing of sites for surveillance and
security.

Project Title: Rapidly Prototyped Single-Wall, Fullerene Nanotube-Reinforced
Composites
Technical Abstract (Limit 200 words)
NASA is seeking rapid prototyping (RP) processes that can produce functional prototypes and working models, which will establish state-of-the-art manufacturing technologies to construct future spacecraft. Single-wall nanotubes are expected to exhibit spectacular mechanical, electronic, and magnetic properties. With such great promise, a logical use of nanotubes is in composites to improve the properties and performance of the matrix material. Lone Peak Engineering (LPE) proposes a RP process to directly produce composites reinforced with single-wall nanotubes. These composites will be used in functional applications as prototypical components or as tools to form other components needed to build future spacecraft.
In this Phase I project, the feasibly of LPE's RP process to build functional nanotube-reinforced composites (NTRCs) will be demonstrated. Two matrix materials will be examined: 1) an epoxy-based resin that will result in composites similar to the pre-pregs that are currently used as tooling at NASA and 2) titanium metal matrix composites, which can be used as functional prototypes and working models.
During Phase II, the RP process will be refined to allow LPE to fabricate pre-preg-like composite tooling. This tooling will be delivered to NASA-Johnson for evaluation in the production of panels for the X-38 spacecraft. Functional titanium-matrix composite prototypes will also be prepared for evaluation in specific NASA-related applications. The tooling and functional prototypes will be delivered to NASA for evaluation in their intended applications at the end of the Phase II project.
Potential Commercial Applications (Limit 200 words)
The commercial applications of this technology lies
in the rapid fabrication of tooling, functional
prototypes, and working models. There is strong
commercial demand functional prototypes with
shorter turnaround times, especially when only
small quantities of parts are ordered. The RP
process can meet this commercial demand for
functional RP components. Industrial sectors
interested in this capability include the aerospace,
medical, sporting goods, transportation, and power
generation industries.

Project Title:
Carbon Nanotubes for High Capacity
Fuel Storage Systems
Technical Abstract (Limit 200 words)
One of the most intriguing applications of
nanotubes is in use as an absorptive/adsorptive
material for hydrogen storage, where the high
surface area dn graphitic naure of carbon
nanotubes can be used to significantly reduce the
pressure and temperature of containment, as well
as potentially dramatically increase the storage
capacity of a storage vessel with a given volume.
The observation that carbon nanotubes can absorb
and adsorb large amounts of hydrogen offers the
prospect that carbon nanotubes can be used for
high capacity, low volume fuel storage vessels for
improved range and/or reduction of tank volume.
The availability of low-cost carbon nanotubes based
on the high volume production process of nanotubes
will enable cost-effective near-term exploitation of
this physical phenomenon. The objectives of the
Phase I work are to demonstrate the feasibility of
using carbon nanotubes for hight capacity hydrogen
storage, and to determine relationships between
fiber size and morphology to hydrogen storage
capacity and thermal stability of the system.
Potential Commercial Applications (Limit 200 words)
Potential aerospace uses of this technology include
hydrogen storage for propulsion or power (fuel
cells). Compact storage of hydrogen could be
enabling technology for the transportation industry.

Applications of Single-Walled Carbon
Nanotubes
Technical Abstract (Limit 200 words)
The overall goal of this program is to develop a new
class of nanocomposite electronic materials from
single-walled carbon nanotubes. The properties of
carbon nanotubes offer a unique solution for
fabrication of practical electronic materials.
However, development of practical carbon
nanotube devices has been limited, and still remains
at the laboratory level, despite the substantial
amount of time and money that has been devoted to
studying their properties.
Specifically, in Phase I, we will demonstrate the
feasibility of our approach by preparing useful
materials that utilize single-walled carbon
nanotubes, fabricating prototype electrodes, and
then testing the them for the following electronic
properties 1) specific capacitance (farads/g), 2)
specific energy (Wh/kg), 3) energy density (Wh/L),
4) cycle lifetime, and 5) ease of manufacturing and
cost.
Based on successful proof of feasibility in Phase I,
we will pursue a Phase II program where emphasis
will be placed on optimizing the most promising
candidates identified in Phase I. Phase II will
involve the design and development of prototype
devices and demonstrating their utility.
Potential Commercial Applications (Limit 200 words)
The projected market for energy storage devices
such as ultracapacitorsis expected to exceed
exceeds 1.3 billion dollars by the year 2000. This
represents a substantial economic opportunity for
development of such devices. Utilization of carbon
nanotube technology in this arena will require
improvements in technical performance and cost
specifications in order for a practical device to
reach the marketplace.
The electronic devices we propose to develop in
this program will have widespread application in the
automotive industry, consumer electronics, energy
management in computers for start-up and memory
back-up, cellular phones and emerging
technologies.

Project Title: Large Scale Synthesis of Single-Walled Nanotubes
Technical Abstract (Limit 200 words)
Single-walled carbon nanotubes (SWNTs) or Buckytubes, with a diameter of only 1.5 nm, represent the ultimate carbon fibers. The high tensile modulus of the tubes, combined with their extremely large aspect ratio and low density, make them ideal candidates for use as structural reinforcements in composite materials. However, before such applications can be taken seriously, a truly large scale, economic process for the synthesis of SWNTs must be developed. The leading current method for their production utilizes an electric arc between two catalytic metal doped carbon rods, a batch process that yields only grams per day. TDA Research, Inc. (TDA) proposes a new synthesis route based on the thermal decomposition of hydrocarbons in the presence of a gas phase metal catalyst, a continuous process that can be readily scaled to industrially relevant capacities. A modification of this process is currently used for large scale commercial production of fullerenes at TDA.
Potential Commercial Applications (Limit 200 words)
SWNTs have been proposed as lighter, higher strength replacements for carbon fibers in composite materials, as well as field emitters for flat panel displays, replacing liquid crystal displays. Other applications include lubricants, in vivo biological sensors, and vessels for performing nanoscale chemical synthesis.

VOC-Compliant Primerless Silicone
Coatings for Corrosion Control
Technical Abstract (Limit 200 words)
A VOC-compliant anticorrosion coating is proposed
for maintaining structural metals such as aluminum
and steel in corrosive field environments. The
proposed research explores the feasibililty of using
an aqueous dispersion of silicone resins stabilized
with novel polymeric surfactants and pigmented
with non-toxic anticorrosive additives to yield
coatings with excellent inherent adhesion to metals
and high corrosion inhibiting ability. The proposed
anticorrosion formulations, although waterborne,
would possess the ability to displace absorbed
water from the surfaces of poorly treated metallic
substrates and adhere strongly without the need for
pre-coat priming. The substitution of multi-function
polymeric surfactants for conventional surfactants
should significantly reduce the emissivity of the
resulting coatings. The interaction of the proposed
coating components and hydrated metal surfaces
will be computer simulated to optimize the unprimed
coating-substrate adhesion and barrier properties.
The VOC-compliant coatings would be tested
against conventional solventborne silicone coatings
for adhesion and corrosion inhibition. The ability to
form inherently adherent, durable barrier coatings
over poorly treated structural metal alloys without
the need for volatile organic solvents would
represent a signficant advancement in corrosion
engineering and aerospace maintenance
technology.
Potential Commercial Applications (Limit 200 words)
The benefits of a waterborne coating for improving
the corrosion resistance of structural metals include
reduced workplace health hazards, lower disposal
costs, greater system reliability, and improved
mission readiness. Potential commercial
applications lie in the manufacture and maintenance
of military, industrial and aerospace vehicles and
equipment.

Project Title:
Self-Priming Silicone Coating
Technical Abstract (Limit 200 words)
Silicone coatings are exceptionally hydrophobic and
stable to most common chemical and weathering
processes, making them excellent anti-corrosion
coatings for materials subjected to extreme
environments. Unfortunately the adhesion of most
silicone coatings to metallic substrates is poor
without the application of a primer coat. To
maximize the adhesion and corrosion protection
afforded by silicone coatings, TDA Research Inc.
(TDA) will develop polymeric additives which will
act as internal priming agents for a wide array of
commercial silicone coatings. These additives are
expected to be effective adhesion promoters even
at concentrations below 1%. Self-priming silicone
coating formulations will save the time and money
associated with application of a separate coating of
primer. Additional potential benefits include the
reduction of volatile organic chemical (VOC)
emissions during the coating process and improved
corrosion protection of the coated metals.
Potential Commercial Applications (Limit 200 words)
Self-priming silicone coatings would find
commercial application in most of the fields where
silicone coatings and sealants are currently used,
including high temperature-resistant,
corrosion-resistant, and hydrophobic barrier
coatings as well as silicone caulking and
construction materials. Silicones are also being
developed as biofouling-resistant marine hull
coatings to replace the environmentally
unacceptable metal salts currently employed. All of
these silicone coating systems would potentially be
improved by incorporating self-priming silicone
additives.

Project Title:
Corrosion Protection Using Surface
Spontaneous Polymerized Coatings
Technical Abstract (Limit 200 words)
The environment around Kennedy Space Center
(KSC) is extremely corrosive. Not only are
structures subjected to near tropical sea coast
conditions of salt spray, humidity, rain, and high
temperatures, but acidic rocket exhaust further
accelerates material degradation even on
struc-tures removed from the blast zone. A new
coating procedure, surface spontaneous
polymeriza-tion, offers a low-cost, environmentally
benign process to deposit high-performance
coatings on a variety of materials. In this
procedure, a solution of monomers and organic
inhibitors is ap-plied to a substrate. Unlike
conventional coating methods, polymerization does
not occur in so-lution, but only at the surface. The
result is a conformal, adherent, tough polymer
coating with-out the small defects inevitable in
traditional coatings. The coatings can be used as
stand-alone coatings or as primers for topcoats
depending on service conditions and required
coating proper-ties. The surface spontaneous
polymerized coatings have been demonstrated for
both aluminum and steel in the laboratory and initial
salt spray testing has shown excellent corrosion
protection. In response to NASA 11.01, DACCO
SCI, INC., in conjunction with the University of
Connecti-cut, proposes a Phase I SBIR program to
develop this coating procedure to provide improved
corrosion protection to KSC ground support
equipment and infrastructure.
Potential Commercial Applications (Limit 200 words)
The technology developed in the program is

Project Title:
Enhanced In situ Bioremediation of
Chlorinated Hydrocarbons
Technical Abstract (Limit 200 words)
Soil and groundwater contamination by chlorinated
ethenes, such as trichloroethylene and
dichloroethylene, is a widespread environmental
pollution problem. In many instances, it is standard
practice to excavate and transport the
contaminated soil to a suitable landfill or to
incinerate the soil to remove the contaminant. Such
practices are expensive, environmentally disruptive
and require extensive permitting. On-site and in
situ biological treatment of contaminated soil is a
safer and more economical method of permanently
solving this problem. This proposal describes an
unique in situ treatment method that uses low-cost
reactive micro-particles, introduced into the soil or
ground water to enhance biological degradation of
contaminants by the soil's native microorganisms.
The method has a high potential for public and
regulatory acceptance because of its low
environmental impact. The targeted contaminants
are degraded and the materials that remain in the
soil are environmentally benign. The method is
entirely passive, offering the potential of lower
operating and maintenance costs compared to
existing in situ methods. Adding the particles to the
soil does not require engineering modification of the
site and the flow of ground water is unaffected. If
the Phase I feasibility study is successful, a field
study of the method will be carried out at a NASA
site.
Potential Commercial Applications (Limit 200 words)
The commercial potential of the proposed method
arises from its ability to be used as a primary or
secondary technology for the treatment of
underground formations contaminated with
hazardous organic wastes. The method can be set
up promptly after accidental pollution takes place,
and it has the potential to be easily applied. This
technology can be readily transferred to the
commercial sector.

Project Title:
Fiber Optic, Molecularly imprinted
Sensors for Long Term Monitoring
Technical Abstract (Limit 200 words)
This proposal describes a fiber optic sensor based
on a molecularly imprinted coating for the specific
and continuous monitoring of hazardous
environmental compounds. Sol gel films
polymerized in the presence of the target molecules
will coat the optical fiber, creating molecular
imprints of the target. Fibers will be coupled to a
compact, low power fluorometer for evanescent
field excitation, detection and data recording. The
use of molecularly imprinted sol gels, rather than
antibodies, will create a durable probe for extended
use and long term storage. Unlike other sensor and
synthetic ligand projects, this effort applies
optically compatible and durable materials (sol gel)
to a sensor system that is well suited to reliable
field monitoring. Phase I objectives are to fabricate
molecularly imprinted probes to detect toluene and
polychlorinated biphenyls, demonstrate their
operation with compact instrumentation, and
characterize the stability of the system over a 1-2
week period. Successful Phase I and II efforts will
result in a prototype fiber optic sensor system for
continuous field monitoring over periods of weeks
to months. These systems would be deployed at
testing and launch sites to monitor runoff,
groundwater, and storage tanks.
Potential Commercial Applications (Limit 200 words)
In the waste treatment and environmental hazard
industries to monitor ground and surface water,
bilge, storage ponds, and recycling systems.
In chemical and biochemical manufacturing as an
on-line chemical process monitor.

RUGGED LASER DIODE OXYGEN
SENSOR
Technical Abstract (Limit 200 words)
Oxigraf has developed a small, rugged oxygen
sensor using laser diode absorption spectroscopy
over a 0.1 m path which meets all the NASA
requirements except range. Oxigraf will adapt the
sensor to a compact, multipass 1 m cell to
demonstrate all requirements including range in
Phase I. In Phase II, the design will be tooled for
low cost manufacturing, greatly extending the
practicality of the technology for medical and trace
oxygen analysis. In addition, in Phase I, Oxigraf will
investigate adapting the small (0.001 cubic meters)
sensor with other laser diodes to measure hydrazine
and monomethyl hydrazine. If laser diode
measurements of hydrazine are feasible, Oxigraf
can implement a combined oxygen/hydrazine
analyzer in Phase II.
Potential Commercial Applications (Limit 200 words)
Oxigraf has manufactured over 1500 laser diode
oxygen sensors for use in medical operating room
and intensive care monitors and has submitted a
510K application to the FDA for approval of a
stand-alone oxygen analyzer. These sensors
measure oxygen from 5 to 100% with a response
time of 0.1 second and accuracy of 0.1%. If this
technology can be adapted at low cost to trace
oxygen analysis (250 ppm) and to "mainstream"
measurements on the respiratory circuit airway, the
market can be expanded by a factor of ten. In
addition, the capability for trace analysis will permit
industrial applications such as food processing and
semiconductor processing.

ADVANCED CORRELATION BOLT
GAGE
Technical Abstract (Limit 200 words)
ARVC will develop portable, reliable, and easily
operated instrumentation for reliable tension
measurement in critical bolts, based on correlation
and other mathematical and physical techniques.
Specifically, we will combine multiple mathematical
algorithms including cross-correlation and
phase-slope delay determination with improved
transducers and electronics having multifrequency
and/or chirp capability in order to increase the
number of ultrasonic echo time determination
modalities, and thus increase the reliability of the
time measurements and the consequent estimations
of bolt tension. We will incorporate temperature
measurement into the ultrasonic transducer to
increase the reliability and user-friendliness of the
overall system. We expect to greatly increase the
accuracy and performance reliability of ultrasonic
bolt tension measurements, as well as the ease of
use of the instrument itself. The resulting
instrument will find application throughout NASA
and all of industry, and its benefits will be improved
accuracy and reliability of tension measurement in
critical fasteners.
Potential Commercial Applications (Limit 200 words)
The advanced bolt gage developed from this work
will find application wherever critical fasteners
(very lightweight in comparison to the loads they
bear) particularly bolts or stud bolts are used. This
bolt gage will find application in all of aerospace
industry and vehicles, in all of defense industry and
vehicles and weapons, in all of the chemical and
other process industry, in all pipelines, in all
manufacturing, in all of the nuclear industry -
anywhere high strength, lightweight in comparison
to design load bolts (or other fasteners) are used.

Technical Abstract (Limit 200 words)
The objective of this SBIR effort is to research and
develop a user-friendly decision support software
system to support the application of innovative
industrial engineering (IE) models and technologies
for complex processes at the Kennedy Space
Center (KSC). The system will facilitate the design
and measurement of maintenance, support, and
other service operations at KSC and provide
decision support capability for relating
process-level and organizational-level metrics.
Deliverables of this Phase I SBIR program include
a working model for at least one KSC process and a
prototype of the software. Overall, this effort
addresses the generic challenge of "doing more
with less" and is aimed at reducing cost and
turn-around time of KSC operations.
AET, Inc. proposes to develop industrial
engineering models for the KSC operations and to
integrate these models into a user-friendly
software-based decision support system. AET has
had several years experience at developing
statistical simulation tools for complex
manufacturing and design activities. At the heart of
these tools is the use of a statistical technique
known as design of experiments (DoE). This
technique is embodied in a software technology
called STADIUM which has been developed by
Florida Institute of Technology under funding from
SEMATECH and DARPA.
Potential Commercial Applications (Limit 200 words)

Project Title: Raman Spectroscopy as a Non-Invasive Indicator of Protein Crystal Quality.
Technical Abstract (Limit 200 words)
Protein crystallography research supporting structur-based drug design requires that a single crystal be selected prior to mounting and freezing for x-ray diffraction. The only method available for determining which crystals are candidates for x-ray diffraction, I.E. which are more perfect in molecular arrangement, is by visual inspection by a trained observer. A non-invasive tool for determining which crystals could provide better data in x-ray diffraction would prove very useful in structure-based drug design by speeding the time from crystallization to structure determination. Raman spectroscopy is just such a technique. It is an optical light-scattering technique for determining the molecular composition of materials or their crystal lattice structure. This technique would increase the likelihood of obtaining high quality structural data for a particular protein at reduced cost by decreasing the use of expensive and time consuming x-ray diffraction facilities by screening crystals prior to diffraction for the degree of perfection. This innovation will further NASA's long standing support for the advancement of protein crystallography and structur-based design.
Potential Commercial Applications (Limit 200 words)
The proposed innovative crystal evaluation system will be of tremendous value to crystallography, chemistry and pharmaceutical laboratories worldwide. The combined market for these scientific disciplines is substatial and the proposed devices will play a vital role in their future. Protein crystal growth is generally recognized as the major bottleneck in crystallographic structural investigations, which are of paramount importance in elucidating fundamental structure/function relationships and in structure-based drug design. This non-invasive method of crystal evaluation utilized prior to x-ray diffraction will produce better structural data at a lower cost.

Project Title: Low Cost Fabrication of High Temperature Polyimide Matrix Composites
Technical Abstract (Limit 200 words)
This project addresses the fabrication of composite materials suitable for high temperature launch vehicle and spacecraft applications, where high specific strength and stiffness reduce weight and increase performance. Organic matrix composites have been formulated which demonstrate good performance at temperatures up to 371 C (700 F). These composites are typically fabricated with polyimide matrix materials, which are difficult to process due to high viscosities, use of solvents, production of volatiles during cure, and high molding temperatures and pressures. The high cost of reactants as well as the toxicity of some components are also significant issues. This fabrication method combines aspects of resin transfer and resin infusion fabrication methods, and allows for removal of solvents and condensation by-products during the cure cycle. This method reduces tooling, labor, material, and scrap costs. A low-cost polyimide, which has demonstrated excellent performance at temperatures up to 371 C (700 F), was selected for development of the process. This material is representative of the entire class of materials, and fabrication methods developed in this program will be directly applicable to other condensation polyimide systems. The utility of the materials and processes will be demonstrated by characterization of their mechanical properties at temperatures up to 371 C (700 F).
Potential Commercial Applications (Limit 200 words)
The proposed program will enable the fabrication of composite parts using intractable polyimide matrix materials by low cost processes. The materials and processes will be immediately applicable to fabrication of aerospace components and cost reductions will allow insertion of this technology into automotive, industrial, and commercial applications.

Project Title: Integrated Dynamic Cell Culturing System for the Bioprocessing Facility
Technical Abstract (Limit 200 words)
Space bioprocessing has evolved into a dynamic R&D program that explores factors affecting human habitation of space, development of biomedical technologies, and enhancement of life on Earth. A significant component of this program focuses on biomedical research at the cellular level, resulting in the need for innovative equipment for culturing cells. The proposed innovation is a teleoperated, perfused cell culturing system, which incorporates internal video and the ability to filter cells from medium and wash them before fixation. Our proposed system incorporates micro-sensors, which monitor the pH and glucose levels within the culture to provide investigators with the unprecedented opportunity to control the growth and development of the cells on a real-time basis. Further, our system fits within a compact, lightweight and fully contained bioprocessing cassette that allows on-orbit sample changeout and enables easier transport to and from the International Space Station. The resulting integrated DYNAmic Cell CULTuring (DYNACULT) cassette operates within the BIOprocessing FACility (BIOFAC) developed by SHOT. DYNACULT is capable of producing a wide variety of cultured cells and transplantable tissues, and has the potential to significantly impact future space exploration, commercialization of new biomedical products and services, and the quality of life on Earth.
Potential Commercial Applications (Limit 200 words)
Our Phase I research is expected to result in commercial product and research applications of the DYNACULT technology that will be useful both in space and on Earth. Commercial product applications for both NASA and the private sector are anticipated from innovations associated with miniaturization of DYNACULT's video, sensor and sampling technology. These innovations could have significant impact on the biomedical equipment market, as well as other markets associated with communications and transportation equipment where miniaturization is an ongoing effort. Research application of the DYNACULT technology could result in transplantable tissue and protein products from cells, microencapsulation of pancreatic cells, and improved treatments for dysfunctions associated with aging, the immune system, and nerve cell disorders. Tissue obtained from microgravity culturing could be used for vessel wall repair and for heart muscle patches. Tissue cultivated through biotechnology processing could replace synthetic materials being used in joint replacements. DYNACULT research in microgravity could increase production and reduce the cost of protein products harvested from leguminous cells, which are used for the treatment of cancer and alcoholism. Furthermore, DYNACULT ground and space experiments with lymphocytes could facilitate design of drugs to slow the aging process.

Project Title: Color Multifunction CMOS APS Imager for Telemedicine
Technical Abstract (Limit 200 words)
The proposed innovation to be addressed in this work is the development of a low cost, high resolution CMOS Active Pixel Sensor digital color camera-on-a-chip for Telemedicine and Health Diagnostic Services. Multifunction sensor design will allow NASA to use the CMOS APS camera for both Dynamic and Static Imaging applications.
Dynamic imaging provides full-motion, high resolution images and may be divided into interactive televideo (IATV), with parties at both ends communicating in real time, and store-and-forward, with video clips transmitted for review at a later time. Static single-frame imaging genereates visual images of much higher resolution than is required for IATV consultations.
In Phase I, optimal architectures to achieve both excellent image quality and a reasonable cost will be investigated. The technical feasibility of obtaining the color images with ultra-high resolution of up to 2Kx2K will be studied. Physical layout and main circuitry to implement the multi-million pixel camera-on-a-chip will be designed and simulated.
In Phase II, the multi-million pixel camera-on-a-chip architecture will be revised and updated. A complete chip, suitable for NASA and commercial applications will be designed, fabricated and characterized.
Potential Commercial Applications (Limit 200 words)
High-resolution CMOS APS technology is expected to be applicable to many consumer, commercial and military applications, ranging from astronomy and biology, HDTV and electronic photography, medical and computer imaging, security and home video to star tracking, target detection, vehicle navigation, automatic inspection and the other CCTV and machine vision systems.

Project Title: Gesture Based Multimedia Information Kiosk to Enhance Science Understanding
Technical Abstract (Limit 200 words)
We propose the development of a public kiosk information system to interact with customers, such as the general public and school children, allowing them to learn about and study programs developed by the Human Exploration and evelopment of Space program in innovative and exciting ways. People will access the kiosk's multimedia information through gesture recognition technology. The self-contained kiosk will contain information updateable on site or through the Internet, and protected against theft and tampering. The information in each kiosk will be tailored to specific audiences and be placed in appropriate locations, such as grade schools, universities, research centers, and public administrative and commercial centers. Using gestures as the kiosk interface has many practical advantages over other forms of input, such as speech or keyboard, including longer input device life (no moving parts), improved hygiene, less system degradation due to noisy environments, and a more intuitive command interface. The goal of the Phase I effort is to design a kiosk using standard video and an inexpensive PC-based multimedia system. Gesture commands will be processed in real-time, with the inputs transformed into information retrieval commands, thus giving the kiosk a "futuristic feel" which has always been associated with NASA.
Potential Commercial Applications (Limit 200 words)
Kiosks are in use almost everywhere, from mall information sites to movie theater ticket purchasing areas. But currently none of them uses gesture recognition, instead relying on unsanitary touch screens or buttons that can break off or get jammed. These kiosks are also unsanitary due to the large number of people who touch the screen or poke the buttons. Our proposed multimedia kiosk, which will use gesture recognition as its mode of input, can be used in all of these places. In addition, such a gesture recognition system could make banking at Automated Teller Machines more intuitive and user friendly. Indeed, automobiles could have built in gesture recognition systems to control various functions (such as the radio, or a map interface). Such gestural control would be more appropriate in an automobile over other forms of control. No need to worry about noise drowning out a voice recognition system, or having the driver loose concentration on the road while searching for appropriate buttons to touch. Finally, if hand and body motions (gestures) can be recognized, then the kiosk could also serve as a surveillance camera, tracking suspicious activity and alerting security when something suspicious takes place.

Project Title: Software Design Methology for Multiagent Software
Technical Abstract (Limit 200 words)
The Phase 1 SBIR project herein proposed is based on an innovative software design methodology for designing and implementing multiagent systems that are robust, reliable, and high-performance. Autonomous agent technology is extremely suitable for complex decision making systems in a wide range of applications, including factory automation, supply-chain integration, electronic commerce, and transportation logistics planning. Until recently the work on multiagent systems has been mostly academic, and progress has been impeded by the lack of software design methodologies and support tools for implementing industry-strength multiagent systems. Intelligent Automation Inc. has been working on multiagent systems for several years. As part of our implementation efforts, we have developed the beginnings of a software design methodology for agents which facilitates reusability of both designs and implementations, as well as facilitates clear communication among participants in the analysis, design and implementation phases. It has the potential to significantly reduce the software development cycle duration and cost, and improve the quality and maintainability of the resulting implementations. The work herein proposed will refine the methodology, and will develop tools based on this methodology.
Potential Commercial Applications (Limit 200 words)
We expect the resulting agent technology and commercial tools to be used to develop on-line commerce applications, factory automation, logistics, and other applications. Our work has instigated great interest in companies specializing in software design and development platforms. Following our research effort, we expect to produce a commercial suite of agent design tools.

Java Empowered Intelligent Agents for
Collaborative and Distributed NASA
Mission Operations
Technical Abstract (Limit 200 words)
Building complex software for large information and
data systems is time consuming and expensive.
Likewise, interfacing with and using legacy
software systems is difficult under the best of
circumstances. NASA has a requirement to conduct
mission operations on a smaller budget and
resources for developing new systems and
maintaining legacy systems are severely limited.
NASA requires new methods and techniques for
constructing large complex information systems.
Intelligent agents and agent-based software have
the potential for significantly changing the way
complex information systems are constructed.
Using intelligent agents, software development
becomes a much simpler and cheaper process
because the software developer deals with
high-level abstractions (agents) rather than
low-level software abstractions (such as objects).
Using the agent paradigm, programming is simply
the process of defining agents and their behaviors.
Reticular Systems Inc. proposes a research effort
leading to the development of a family of DYNamic
Agents for Mission Operations (DYNAMO).
DYNAMO will significantly enhance the software
development process, reduce software development
time and provide additional capabilities (e.g.,
planning, learning and autonomous operations) that
are otherwise difficult to provide in information
systems. The goal of the DYNAMO project is to
show how intelligent agents can be used to
implement mission operations systems.
Potential Commercial Applications (Limit 200 words)
The use of the collaborative agent to create a
framework and environment for distributed
commercial design projects could have a large
horizontal market. In addition, many of the
capabilities of the data retrieval agent, data
archiving agent, and database agent could find use
in many different vertical markets-such as the
travel industry, web searching, industrial design
projects, etc.-where intelligent agent-based
retrieval utilizing conceptual information could be
profitably employed.

Project Title:
Silicon-Based APD Arrays for 1064 nm
LIDAR
Technical Abstract (Limit 200 words)
Many ongoing and future NASA lidar and altimetry
systems and experiments use Nd:YAG lasers
operating at 1064 nm. Single-element,
reach-through silicon avalanche photodiode (APDs)
are presently used as the optical detector at this
wavelength. These systems could all benefit from
the development of a low-noise, silicon-based
imaging array technology with greater than 40%
quantum efficiency at 1064 nm.
The proposed innovation is based on using
advanced materials and device designs to enhance
the APD quantum efficiency at 1064 nm to greater
than 60%. APD arrays will be fabricated and
characterized for optical response, uniformity, dark
current and noise performance. These
photodetectors will have responsivity greater than
100 A/W and detectivity greater than 1E13 Jones at
1064 nm. This design will be scalable to sub-100 µm
pixel dimensions and be compatible with wafer-level
bonding to silicon CMOS readout and preamplifier
integrated circuits.
Potential Commercial Applications (Limit 200 words)
There are many commercial and military lidar
applications at 1064 nm that would benefit from an
imaging APD hybrid array. The APD arrays
developed on this SBIR program would have
enough spectral sensitivity at 1064 nm to enable
those systems to be developed.
This technology can also be readily adapted to a
host of lower-frequency, low-light level applications
including night-vision equipment. Night vision
systems that require several line pairs/mm
presently employ second-generation vidicon
displays based on micro-channel plate technology
typically operating at several kV. A low-cost,
low-voltage, low-power semiconductor APD hybrid
array with pixel dimensions on the order of 10 µm
would be suitable for this application and provide a
substantial market opportunity for this technology.

Project Title:
Fractured Zone Plates for spatial
separation of frequencies
Technical Abstract (Limit 200 words)
The output of a Fabray-Perot interferometer is an
interferometric zone plate when the input is a
monochromatic diverging wave. In a similar fashion
the output of a polychromatic wave will be a
geometric zone pattern of radially changing
frequencies. The individual annular bands can be
sensed directly with a zoned sensor or alternatively
the zone plate pattern may be spatially separated
into individual focused spots with a diffractive
optical element (DOE) or holographic optical
element (HOE). Prior work consisted of fabricating
HOEs with off axis focal planes. Composites were
made by individually masking and stablizing each
zone exposure and replication of a composite could
not be done because of shadows at the smallest
dimensions.
This proposal deals with near on axis DOEs and
ultra thin master HOEs that can be mechanically or
optically replicated as complete devices in one step.
The DOE segments will be formed by punching out
offset annular pieces of several master zone plates
and then assembling the annuli into a secondary
multiplexed zone plate for replication. The offset
distance is the distance between frequency
channels at the DOE focal plane. Hoe designs are
of two kinds, thinly covered master circle to point
converters and master line to point converters. The
latter will enable the use of diffraction gratings in
place of Etalons for wider band frequency
component discrimination. Both cases will enable
the collection of all available signal light into fast
photo diodes arranged in a line or other discreet
pattern.
Potential Commercial Applications (Limit 200 words)
Commercial wind lidars for air traffic safety are a
good application mainly due to the much lower cost
of direct frequency detection over more
conventional heterodyne coherent lidars. Patterns
can also be made to work with high dispersion
gratings, which are easy to use in some broader
bandwidth configurations like wavelength division
multiplexing. An optical Dopplar radar for the
measurement of the relative motion of two objects
may be a viable application. We have no application
in mind to devleop for ourselves but a free space
optical communication company has expressed
interest in a similar multiplexed HOE which would
be enabled by succeding at this product
development effort.

Project Title: Geometric Transformation Using Computer Generated Optical Elements
Technical Abstract (Limit 200 words)
Space Applications Corporation (SAC) proposes a simple, innovative method to convert circular interference fringes into a linear pattern by using geometric transformation with a computer generated optical element. This unique method when included in Fabry-Perot interferometer systems would be a powerful tool for planetary atmospheric observations. The proposed approach exploits the concept f high-sensitivity Moire interferometry. The resulting linear fringe pattern contains nearly all the transmitted energy and can be scanned using commercially available linear array detectors. This method retains the inherent throughput advantages of FPI by enabling the detection of the full intensity pattern. Considerable output signal gain can be realized, thereby reducing the long integration time required for low-emission sources and very extended astronomical objects such as the Gum nebula. The proposed optical elements are simple to fabricate, light weight, low cost, and very reliable and will result in a flight-worthy instrument that is ideally suited for small satellite observations. This new technique for scanning the circular fringe pattern produced by a FPI will have numerous application in various scientific, commercial, and industrial fields and is a major improvement over the state-of- the-art CLIO-FPI technique proposed for many future astronomical observations.
Potential Commercial Applications (Limit 200 words)
Applications include: plasma research; astronomy; remote sensing; x-ray microscopy; neutron imaging; IR surveillance devices; automatic inspection systems for quality control; angle multiplexing for optical fiber communication; solar energy concentrator; accessing optical disk; low and geosynchronous orbits planetary exploration; and comet probe missions.

Miniaturized multispectal imaging
system for small portable UAV
Technical Abstract (Limit 200 words)
The innovation is a miniaturized Multispectral
Imaging Sensor System for use on small UAV's for
aerial remote sensing of the environment. The
airborne sensor will provide imagery in the
400-1100 nm range with 10 nm spectral resolution,
less than 1 meter spatial resolution at 0.5 km swath,
and weigh 2 kg or less. Filters will be selectable and
interchangable for specific applications. A character
generator may be incorporated to insert important
information for post processing into each frame of
video. All data will be transmitted and stored on the
ground at the point of operation.
The system is meant for integration into small
UAV's, as such flexibility and timeliness will be
dramatically increased for data collection of coastal
regions and almost anywhere else as a result of this
innovation. Incorporating this system into a small
UAV will have the advantage of reduced operating
costs and quick transport for data collection. A
small UAV is able to operate in many more areas
than larger UAVs because the operating area
necessary for take off and landing is significantly
less. Systems such as these will further increase the
remote sensing capability of NASA and other
government agencies.
Potential Commercial Applications (Limit 200 words)
Commercial applications of this technology include
the production of sensor systems capable of
integration into low cost and small fixed, free or
rotary wing UAV's. They can be used in aerial
remote sensing applications for agriculture and
water systems as well as other commercial aerial
imagery requirements such as environmental clean
up monitoring, and land management and
maintenance.

Reflection and Thermal Band
Hyperspectral Imager
Technical Abstract (Limit 200 words)
The principle innovations will be a hyperspectral
system covering both the reflection and thermal
infrared bands, and a system which provides
real-time radiometrically calibrated data to
accelerate use of the data. The Phase I project will
provide a detailed conceptual design of a
hyperspectral imager for airborne applications. The
system will cover both reflection band (0.4 to 2.5
microns) and the thermal band (8-11 microns).
Spectral resolution will be 10 nm spectral resolution
from .4 to .9 microns (60 bands), 20 nm resolution
from .9 to 2.5 microns (60 bands) and 125 nm
resolution from 8 to 12 microns (30 bands). Spatial
resolution will be 1 m and 500 m swath width in the
reflection bands (.4 - 2.5 microns) and 1 m ground
resolution and 250 m swath width in the thermal
bands (8-12 microns). The proposed system will
include real time radiometric calibration of all
wavebands. The system will also include active
image stabilization.
Potential Commercial Applications (Limit 200 words)
There are currently no commercial imaging
spectrographs flying which cover both the reflection
band and the thermal band in one high-resolution
sensor. The real-time calibration feature provides
an opportunity to collect high quality calibrated
data, also not available in current airborne systems.
The design of this system should easily lend itself
to activities supporting various commercial, civil,
and military applications. There are a large number
of applications in the areas of geology,
environmental assessment, agriculture, tactical
military and reconnaissance which would strongly
benefit from this technology.
Pacific Island Technology plans to aggressively
pursue a teaming arrangement with an established
aerospace corporation to manufacture, market, and
field complete airborne remote sensing systems
based on this design.

Ultralightweight Silicon Carbide
Space-Based Hyperspectral Sensor for
Coastal Research
Technical Abstract (Limit 200 words)
Remote sensing of coastal regions is a complex
problem which requires very high spatial and
spectral resolution. Space based sensor concepts
are being pushed to provide this high resolution
information within compact, lightweight, and
integrated payloads. SSG proposes the
development of an ultralightweight, innovative,
moderate resolution hyperspectral sensor concept.
The sensor proposed integrates several innovative
technologies: ultralightweight Silicon Carbide (SiC)
optics, a, low-distortion spectrometer relay optical
design, and a newly developed dual-blazed grating
fabrication process. The combination of these
technologies will provide a wide field-of-regard,
high-resolution, ultralightweight sensor concept
which is suitable for coastal monitoring/evaluation.
SSG has extensive experience with SiC optical
systems, the superior bulk materials of SiC,
superior thermal stability (8x better than aluminum)
and excellent specific stiffness (80% of beryllium),
make it ideally suited for ultralightweight, thermally
stable, space-based remote sensing applications.
The innovative, low-distortion reimaging optics and
dual-blazed grating proposed have both been
developed by NASA. SSG will utilize these
important technical advances to produce an
ultracompact, modular reimager. A number of these
1:1 reimager sections will be combined with a wide
field-of-regard, all-reflective optical front end in
order to obtain an innovative high sensitivity,
hyperspectral sensor concept. During Phase I the
overall concept design will be reviewed and a set of
opto-mechanical designs will be generated. The
critical component in the hyperspectral sensor
concept proposed, the low-distortion 1:1
spectrometer relay, will be produced and tested
with support from NASA personnel. A successful
Phase I effort will lead to the development and
testing of a fully functional prototype during Phase
II.
Potential Commercial Applications (Limit 200 words)
A number of NASA, DoD, and commercial
end-users are very interested in space-based
hyperspectral imaging for a number of applications.
Coastal monitoring applications include
environmental effluent/ contamination and
commercial fisheries. From a military perspective
mine countermeasures, submarine detection, and
monitoring of the environmental impact of training
and operations are all areas of interest.

Project Title: High Energy Single Frequency Solid State Laser for Atmospheric Remote Sensing at the Eyesafe 1.5 Micron Wavelength
Technical Abstract (Limit 200 words)
Practical lidar laser transmitters for atmospheric remote measurement applications must be environmentally rugged, efficient, and capable of tuning over a specified wavelength range. Lite Cycles is developing solid state Raman eye safe laser technology for operation at 1.56 microns for applications such as rangefinders and coherent lidar wake vortex detection systems for use around airports with high traffic rates and large aircraft. System Specifications typically require that the output beam quality be nearly diffraction-limited (less than or equal to 2 TDL), with large pulse energies (less than or equal to 500 mJ/pulse) at high repetition rates (less than or equal to 10 Hz), and with a high overall wall-plug efficiency (greater than 6%). Some applications require these sources to be capable of operating in a coherent mode (i.e., injection-locked to a local oscillator). This transmitter has a diffraction-limited output beam and is ideally suited for use in remote sensing applications. We propose a 0.5 J/pulse 10 Hz coherent transmitter that is based on a master oscillator/Raman amplifier scheme that uses existing solid state Raman converter materials.
Potential Commercial Applications (Limit 200 words)
Remote sensing of atmospheric aerosols and clouds, both for military and commercial purposes, are of interest. Systems for detection of chemical and biological aerosols to give early warning of the existence, location, size, and possibly identification of potentially dangerous substances in the atmosphere are viable applications for this technology. Other commercial applications include eye safe ranging and velocity measurement lidar, wind and wind shear measurement lidar, and eye safe night vision systems.

A RAMAN WATER VAPOR MICRO
LIDAR
Technical Abstract (Limit 200 words)
We propose to develop a new micro Raman lidar
(MRL) for remote measurement of atmospheric
water vapor and aerosols. Although its basic
principle is simple, because of the low signal levels,
practical Raman lidars are bulky, expensive and
operate mostly at night. Our proposed MRL
overcomes these limitations by utilizing the Micro
Pulse Lidar concept, to result in a rugged,
affordable lidar with routine day and night
operational capability. A high repetition rate,
compact
diode-pumped frequency quadrupled Nd:YAG laser
(266nm), operating in solar blind wavelength region,
eliminates solar background to allow daylight
operation. A 35cm telescope collects the weak
signal and efficient detection is achieved with
photon counting after blocking elastic scattering
with rejection filters. Water vapor mixing ratios up
to 3km altitude are obtained with vertical resolution
of 100-200m, for 1mJ/pulse laser energy. Ten
minute averaging yields high accuracy (5%) and
good signal to noise ratio (~20) even at 2 km. With
SESI's extensive MPL technology basis, a
moderate cost innovative MRL will be developed.
In Phase I, we will perform a feasibility study, and
critical system performance analysis, as well as
demonstrating a bread-board Raman lidar. After
building a prototype MRL, measurements will be
performed in Phase II.
Potential Commercial Applications (Limit 200 words)
In addition to the NASA's applications of lidars for
remote sensing of atmospheric water vapor many
other applications are envisaged. Raman lidar
systems for measurements of, temperature, O3,
pollutants, atmospheric aerosol etc, for weather and
climate prediction and modeling, for environmental
monitoring, chemical and biological species in
battlefields are some of the anticipated
applications.

Auto-Alignment and Lag Angle
Compensation Technologies for
Autonomous Coherent Lidars
Technical Abstract (Limit 200 words)
Doppler Lidar is uniquely capable of meeting
NASA's EOS tropospheric wind sensing needs.
However, these autonomous coherent lidar systems
will potentially suffer significant SNR loss due to
component misalignment and lag angle effects.
Launch vibration and thermal loading induced
component misalignment is a serious concern which
can potentially be solved using clever
auto-alignment schemes. For a space based
transceiver, lag angles on the order of 100's of
beam widths result, even for moderate scan rates
(~7 RPM). To date, neither of these technologies
have been sufficiently developed to satisfy NASA's
EOS measurement needs. CTI also has a strong
interest in solving these technological problems for
its ground based autonomous lidar systems.
Auto-alignment technologies will result in
lower-cost sensors with greater autonomy. Lag
angle compensation will facilitate faster scan rates,
larger apertures, and greater volumetric coverage
capability. In the proposed Phase I effort CTI will
investigate designs exhibiting a high level of
synergism between NASA's and CTI's
requirements for the following three lidar
subsystems: 1) laser auto-alignment, 2) transceiver
auto-alignment, and 3) lag angle compensation. This
Phase I effort will leverage upon experience and
knowledge gained during a previous CTI R/R&D
program, which investigated transceiver
performance as a function of laser and transceiver
misalignments.
Potential Commercial Applications (Limit 200 words)
Potential commercial applications for these
lower-cost faster scan rate autonomous sensors
include, use of the sensor at airports for detection
of hazardous aircraft wake vortices and windshear,
increasing airport capacity, improved helicopter
operations onboard small to medium sized ships,
and airborne wind measurement systems for
improved ride quality and gust alleviation. In
addition, the auto-alignment concept will find many
commercial applications wherever two or more
beams need to be aligned to each other, such as is
required in non-linear optics, single-mode fiber
optic beam launching, etc.

Ultrabright Laser Diode for Lidar Wind
Measurements
Technical Abstract (Limit 200 words)
Solid-state lasers of Tm:Ho:YLF are being
investigated for remote detection of atmospheric
turbulence on aircraft and at airports. These lasers
are most efficiently pumped by 791 nm laser diodes,
but the two current types of laser diodes are either
efficient but unreliable or reliable but inefficient.
The proposed new laser diode will eliminate serious
operational limitations that plague the two
presently-available types (AlGaAs which exhibits
facet degradation at high power levels, and
InGaAsP which has low efficiency). By utilizing an
InGaP guide layer (which does not exhibit facet
degradation) and an AlGaAs cladding layer (which
is in a region of the laser where the optical field is
almost zero) the proposed laser diodes will have a
combined reliability and efficiency not currently
possible. The proposed program involves design,
fabrication, and test of such a 791 nm
InGaP/AlGaAs laser diode. It is anticipated that
this laser will exhibit no facet degradation at peak
output power levels of 250W. This exceeds present
laser diode output power by over a factor of 2. With
the successful demonstration of this laser diode,
NASA will be able to demonstrate a reliable and
efficient lidar system for remote atmospheric
turbulence detection.
Potential Commercial Applications (Limit 200 words)
Reliable Ho:Tm:YLF lidar systems are urgently
needed for atmospheric windshear and microburst
detection on commercial and civilian aircraft and at
airports. Medical applications for Ho:Tm:YLF
lasers abound because of the strong absorption of
tissue at 2.1 mm. Other commercial applications for
high power, reliable 791 nm laser diodes include
welding, cutting, marking, and materials processing.

Laser Arrays
Technical Abstract (Limit 200 words)
High power, low cost laser diode arrays are needed
to fill many applications including solid state diode
pumps, industrial fiber delivered laser cutting and
scribing as well as many medical and NASA
applications. The usefulness of high power
(>150mW) edge emitting lasers is limited by many

based on the Vertical Cavity Surface Emitting
Laser (VCSEL) technology for pumping at 0.79um
to provide unparalleled performance including high
power (100mW-10W+ CW, 2-1000W+ pulsed),
temperature insensitive operation (threshold
current variation of ± ~1mA over >150°C
temperature range expected), high temperature
operation (to 150°C+), scalability for higher output
powers (10W-100W+ CW potentially achievable)
and low production costs (a 500umx500um array
producing 10W CW can be manufactured for
roughly one dollar). By the end of Phase I, PES will
obtain optimized 0.79um VCSEL design for high
power, low divergence operation. By the end of
Phase II, PES will deliver high power (to10W CW,
1000W+ pulsed) VCSELs for commercial and
NASA applications.

Project Title: Investigation of Packaging Technology for Long-Lifetime Space-Based Lasers
Technical Abstract (Limit 200 words)
Fibertek, Inc. proposes in this SBIR Phase I work to investigate the packaging technology for long lifetime space-based lasers. We will look at the issues related to the lifetime of high-power diode-pumped lasers to be operated on a satellite. The significance of Fibertek?s proposed work is to seek and identify method(s) that will allow the high-power diode-pumped lasers to be safely operated in the space for an interval of 3 years or longer, and be fired for 5 billion shots. Such methods may include the design, development, and improvements of prototypes and new processes to meet the long lifetime equipment of the future space mission.
The Phase I technical objectives are to seek and
devise methods and processes to reduce the failure probability of long lifetime space-based lasers due to particle and outgasing contamination. Our primary objective is to study and characterize the issue of outgasing contamination. We want to find the methods and processes such that, when implemented, they will reduce the risk level of outgasing contamination. We will conduct experimental tests to verify the results of the study, and draw conclusions from the tests. Based upon the conclusions, some conceptual designs of a proposed Phase II prototype laser will be given.

The results of this NASA SBIR have their primary application in space-based laser systems. The packaging methods and processes developed in the program provide the basis for the development of practical long lifetime space-based laser applications.

Near Real-time Forest Fire
Information System (FireCam)
Technical Abstract (Limit 200 words)
Forest fire fighting crews require timely, accurate
information about
the location and progression of a fire for strategy
and decision
making. Existing fire information sources are
deficient in accuracy,
timeliness or both. An advanced system combining
an intelligent
airborne sensor/processor flying over the fire in a
UAV or small
aircraft, air-to-ground data link, and a ground
processor for
providing fire information is proposed. An existing
or new
miniaturized infrared sensor provides input to a new
autonomous
processor which extracts vital fire information from
the image in the
aircraft, adds GPS coordinates, compresses the
data and sends it to
the ground processor through a satellite
communication link.
Improvements derive from linking the two
processors in near real-time,
locating the ground processor at the fire command
post and
coregistering images to a database of high
resolution reference
images. An operator at the ground processor
overlays and conforms the
fire images to the stored reference images. The
resulting images
contain the background scene, fire boundaries, fire
intensities and
locations. Special algorithms and image
compression in the airborne
processor bring the data volume within satellite link
capability.
Successful implementation will provide accurate,
easily interpreted
fire status data that is minutes, rather than hours,
old.
Potential Commercial Applications (Limit 200 words)
Daedalus scanners are used worldwide for fire
fighting applications.
These IR scanners and imagers have been used to
combat forest fires
over the past 20 years but their utility for the fire
fighting team
has been limited by spatial inaccuracies, high
operator skill
requirements and slow response times. The
proposed system, with its
improved capabilities, is a candidate replacement
for these systems.
Every year, Daedalus receives numerous serious
inquiries for fire
mapping systems from the USA, Europe, Asia,
Australia, and South
America. However, the potential buyers need better
performance than is
possible with existing systems. The capability and
performance of the
proposed system meets the needs of these potential
customers. In
addition, this system concept is ideal for use with
the new generation
of high altitude UAV's. NASA, California Forest
Service, and the US
Forest Service/USDA are all candidate customers
for the system on a
UAV.

Project Title: Room-Temperature IR Source for Atmospheric Trace Gas Measurement
Technical Abstract (Limit 200 words)
Quantitative measurements of trace gases in the stratosphere are required for a better understanding of atmos- pheric chemistry. Direct detection of stratospheric trace gases by absorption spectroscopy in the mid-infrared spec- tral region is now performed by lead-salt lasers which require cryogenic cooling, cannot always be tuned to the de- sired wavelengths, and cannot be easily replaced if they fail. Our innovation is a replacement for lead-salt lasers based on the nonlinear frequency conversion of two diode lasers operating in the near-infrared. This laser source meets or exceeds the all of performance specifications of the lead-salt laser, while offering room temperature opera- tion, tunability to any desired wavelength, and modular construction using readily available components. The use of two input lasers allows us to implement a novel scheme for stabilizing the infrared power, leading to more sensitive trace gas detection. During Phase I we will prove feasibility by building a mid-infrared laser source, implementing the power stabilization scheme, and measuring the detection limit for a trace gas such as methane. In Phase II we will produce and deliver a portable laser spectrometer incorporating our innovation to NASA for use in the meas- urement of trace gases relevant to stratospheric studies.
Potential Commercial Applications (Limit 200 words)
A compact, affordable infrared spectrometer for the quantitative remote sensing of trace gasses would be attrac- tive to industries trying to keep up with tightening EPA regulations, as well as to those trying to implement stricter controls over manufacturing processes.

Project Title:
An Advanced UAV System to Support
GSFC - Mission To The Planet Earth
Remote Sensing Validation Programs
(GSFC Code 935)
Technical Abstract (Limit 200 words)
This proposal is to develop an advanced low cost,
highly modular UAV system capable of supporting
various NASA MTPE missions. A need for the
capability to provide extended ground truthing,
repeat coverage for environmental monitoring,
rapid response time, flexibility of operating
performance and ease of payload integration have
been well defined for many research and
commercial applications. A wide variety of
applications exists in the commercial and
government markets for both civil/environmental
and defense/intelligence. Freewing Aerial Robotics
Corporation (Freewing) will utilize its unique
Freewing Tilt-Body design UAV to develop a highly
stable remote sensing UAV system. This system
will have the capability of accepting any number of
small stand-alone remote sensing instruments, and
therefore will support various research and
applications requirements. In Phase I Freewing will:
1) conduct an analysis of MTPE requirements and
develop a detailed conceptual design indicating how
advanced UAV systems can meet these
requirements, 2) conduct multivariate parametric
analysis using its existing computer models and
extensive wind tunnel data to define performance
criteria versus mission requirements, 3) develop a
conceptual design for an advanced, multipurpose
UAV system, and 4) develop a preliminary system
test plan and operations concept.
Potential Commercial Applications (Limit 200 words)
Since the results of this effort will be the
development of a highly flexible low cost UAV
system, its commercial potential is significant and
covers all remote sensing applications.
Potential applications involve the detection and
mapping of a wide variety of objects and materials.
Commercial applications include: management and
monitoring of coastal zones, wetlands, forests,
agriculture, urban planning, municipal zoning and
management, reef assessment, pollution
monitoring, and low cost field testing of new
instrumentation.

Project Title:
Self-Tuning Kalman Filter for
Autonomous Orbit Estimation
Technical Abstract (Limit 200 words)
For any NASA mission, a key component to the
operational success of the mission, for both
operations planning and science data processing, is
orbit determination. Traditional methods of orbit
estimation are very good at producing state
estimates when the force and data noise models are
well defined. However, practical implementations of
orbit estimation require a large staff of operations
personnel to manually adjust tuning parameters to
account for irregularly occurring but repeatable
variations in the force and data noise models. Such
labor intensive processes are costly.
AI Solutions proposes to develop a self-tuning orbit
estimation system that uses a Kalman filter to
estimate orbit states and a neural network to
actively monitor and control the estimation process.
A neural network integrated with a Kalman filter
will remember and classify the complex
relationships between dependent (state estimation)
and independent (tuning parameters) data. Based
on these complex relationships and error feedback,
a neural network will tune the Kalman filter,
thereby replacing the manual tuning process and
significantly reducing operations costs. Once
proven on the ground, this system can then be
integrated with on-board maneuver control systems
for an autonomous on-board navigation and control
system.
Potential Commercial Applications (Limit 200 words)
With the current growth of the commercial
spacecraft market, there will be many industry
customers who can benefit greatly from this
innovative technology. A self-tuning Kalman filter
for orbit estimation will be of immediate use to all
government agencies and companies who are
performing spacecraft operations. This autonomous
orbit estimation tool will allow significant reductions
to operations costs for commercial companies who
must constantly monitor and perform orbit
determination on numerous spacecraft.
Constellations such as IRIDIUM, ORBCOMM,
and Teledesic are just a few of the potential
commercial customers of this technology.
Kalman filters also have numerous applications in
other areas where large amounts of data with
complex relationships need to be processed for use.
Signal processing is one such area where a neural
network / Kalman filter combination that can be
trained to operate autonomously would be of
significant value in the commercial market. The
ability to create a Kalman filter / neural network
combination that can be easily customized and
trained to accept any form of data will allow this
product to be marketed in many forms throughout
the aerospace and telecommunications industries.

Project Title:
MINIATURE THREE CHANNEL
CLOUD TOP HEIGHT
SPECTROMETER
Technical Abstract (Limit 200 words)
We propose to develop a miniature three channel
spectrometer to
measure cloud top height from space and airborne
platforms. Cloud
top height is a key parameter required for accurate
ozone retrieval
from TOMS and SBUV measurements, and for
proper analysis of earth's
radiation balance, in radiation and general
circulation models.
Radiometric measurements of thermal-IR that
currently provide cloud
top height are prone to serious errors, and their
precise
determination is thus essential. Our proposal
combines three
complementary techniques - thermal-IR (11-12um),
oxygen band
absorption technique in near-IR (760-770nm), and
filling-in effect
of solar UV Fraunhofer Calcium K and H lines
(390-400nm), to
simultaneously measure radiation from the same
region of the cloud.
Solar radiation scattered from the cloud and its
thermal emission are
collected by a small telescope and analyzed with a
novel 3-band
spectrometer with moderate resolution. Spectra of
the Fraunhofer lines
and oxygen A band are obtained with a diode array
detector, while a
HgCdTe detector measures the thermal IR through
a pass band filter.
In Phase I we will design and demonstrate the
feasibility of the
instrument. In Phase II, a rugged compact
spectrometer will be
built and flown on an aircraft to measure cloud top
height.
Potential Commercial Applications (Limit 200 words)
Several applications for the cloud top height sensor
are anticipated.
Most of the environmental, meteorological and
military satellites
require a miniature passive sensor for accurate
determination of cloud
top height. We also expect to further develop this
concept into an
inexpensive passive sensor for use as a cloud
ceilometer for avionic
applications at airports and other military launch
sites.

Project Title:
A Multi-Spectral Imaging Sensor
Utilizing a Fabry-Perot Etalon
Technical Abstract (Limit 200 words)
The goal of this project, is the construction of an
LWIR (8-12 mm) liquid crystal Fabry-Perot etalon
coupled with a LWIR imaging system. This
combination of technologies will result in a versatile
spectral imaging instrument. We propose to adapt a
technology that has been developed and refined by
SSI in the .5 - 2.5 mm spectral region to the 8-10
mm spectral region. We will use birefringent liquid
crystals as the tuning element of a large diameter
(2" for phase I) etalon. The etalon will have no
moving parts and will require no active feedback for
control, making it much more robust than PZT
based systems. This LC etalon, which is a single
monolithic unit, is nearly impervious to vibration or
shock making it ideal for use in chemical imaging or
spectroscopy systems that need to operate in
hostile environments. The sensor system proposed
here is ideally suited to current NASA
requirements for smaller, hyperspectral imaging
systems capable of being used in-orbit or on
airborne platforms.
Potential Commercial Applications (Limit 200 words)
Numerous environmental and related applications
benefit from monitoring with spectroscopic
methods. The proposed sensor would be able to
monitor currently regulated molecular species such
as, oxides of sulfur, carbon and nitrogen. Spectral
imaging makes it possible to identify chemical cloud
composition and to determine the physical location
and extent of chemicals. In agricultural applications
spectral imaging techniques can be used to monitor
the affect and distribution of water, insecticide and
herbicide remotely. If multiple crops are growing in
the same land area spectral imaging can identify
the type and extent of each type of plant. Another
important application is medical imaging, tumors
can produce temperature differences in or near the
skin, which can be imaged with this type of system.

Project Title: A Small Rugged Uncooled LWIR Hyperspectral Imager
Technical Abstract (Limit 200 words)
By optimally sampling the spectrally encoded output from a Fourier-Transform Interferometer with an imager consisting of a staring, uncooled microbolometer Focal Plane Array Camera, Visidyne proposes to develop a Spectral Imager capable of acquiring simultaneous high resolution Thermal Infrared (TIR), spectral and spatial data. The design provides for a complete trade-off, if so desired, between frame rate, spectral resolution, spectral coverage, and sensitivity, and allows such tradeoffs to be made in real time in the field or in orbit. Key to the design is the capability to precisely and rapidly position the interferometer moving mirror, which makes it possible at one extreme to generate broad-band images (the imaging radiometer or FLIR mode), while at the other extreme maintaining a spectral resolution of / 1% (the hyperspectral imaging mode). In the latter mode, the rapid mirror positioning capability can be used to selectively under-sample the interferogram, which produces high spectral resolution over a limited spectral band width. The concept addresses NASA's stated need for hyperspectral imaging instrumentation for Mission To Planet Earth-observing and other exploration programs with a design that is logistically undemanding in terms of size, weight, power, and that requires no cooling.
Potential Commercial Applications (Limit 200 words)
The availability of a dependable, small, rugged uncooled instrument to measure thermal infrared spectral an spatial emissions opens up new commercial possibilities for such applications as the Driver Vision Enhancement, environmental monitoring and of course remote sensing, which is become increasingly commercialized.

Project Title: A Hyperspectral Imagery Exploitation Tool Using Evolutionary Computing Methods for Remote Sensing Applications
Technical Abstract (Limit 200 words)
An innovative software imagery exploitation tool is proposed for visualizing and assessing large volume imagery sets like hyperspectral data using state-of-the-art pattern recognition techniques. The application incorporates methods from Evolutionary Computing that includes an Artificial Neural Network in combination with an Evolutionary Algorithm to automatically solve the materials detection and subpixel spectral mixing problem. The proposed Evolutionary Computing approach provides a non-parametric search of the solution space which is guided by a model based cost function that allows for rapid and flexible exploitation of the imagery data. The solution to this problem permits the identification of the constituent materials that comprise a pixel subtense (footprint) on the terrain from remotely sensed data and allows an end user to automatically identify objects, chemicals, environmental effects and specially tagged materials that are useful in search and rescue operations. The end product to be developed during this project is a commercial software application that will provide end user visualization of hyperspectral imagery and automated interpretation of spectroradiometric data in a user friendly environment.
Potential Commercial Applications (Limit 200 words)
This project will lead to innovative large volume imagery exploitation algorithms and software tools which have wide commercial applications, such as assessment of environmentally sensitive locations, detection of potential mining sites, forestry, urban planning and agricultural assessment.

Automated IFSAR Classification
System
Technical Abstract (Limit 200 words)
Telesis Corporation proposes to develop an
Automated IFSAR Clasification System that will
produce radiometrically corrected maps of the
normalized cross section (sigma-0), with classified
regions and delineated features, from
interferometric synthetic aperture radar (IFSAR)
data. The Phase I research will focus on necessary
pre-processing, clustering, and classification
algorithms that can identify and measure the
vegetation coverage, soil moisture, and soil
roughness on either flat or mountainous terrain.
The algorithms will use the digital elevation model
(DEM) produced by the IFSAR to correct the
sigma-0 values in the SAR image that were
estimated using a flat earth assumption. They will
also use this DEM to measure the dependence of
various parameters on incidence angle, such as
sigma-0, or for polarimetric SAR, the amplitude
ratios or differences in phase of various terms in
the polarimetric covariance matrix. These
dependencies on incidence angle, along with other
features derived from the SAR image, will be
compared to a library of feature vectors stored in a
database and used to cluster and classify the
regions in the image.
Potential Commercial Applications (Limit 200 words)
The system will improve the utility of SAR imagery
for land cover and land use analysis, including the
classification of vegetation coverage and the
measurement of forest canopy height, biomass, and
soil moisture. The greatest improvements will be in
mountainous areas having significant terrain relief.
The software will be useful to vendors of
commercial IFSAR data for the creation of
value-added products that complement the SAR
ortho-mosaics and DEMs already on the market.

Automated Resolution Enhancement of
Satellite Images
Technical Abstract (Limit 200 words)
Commercial imaging satellites will soon be capable
of economically producing 1 to 3 m resolution
panchromatic images. This resolution needs to be
improved to support urban planning, agribusiness,
land use, forestry management, etc., where aircraft
sensors customarily produce 0.15 m resolution
imagery, at relatively high cost.
Recent advances in image resolution enhancement
and precise image navigation will be applied to
limited resolution satellite image data to produce
significantly finer resolution images. Software will
be developed to apply these technologies as routine
and efficient integrated procedures, to fill the need
for timely processing of available large scientific
and commercial data sets.
Existing, directly applicable technology is
sufficiently mature for this innovation. An
a-posteriori estimation procedure, applied to
repeated AVHRR images with a resolution in the
range of 1 km, has achieved a five-fold
improvement. The ability to reliably enhance
topographical features, man-made objects, and
vegetation will provide scientific and commercial
users a new fertile source of detailed data.
Potential Commercial Applications (Limit 200 words)
With the advent of commercial satellites, data
acquired from remote sensors is finding application
in the private sector. Increased resolution of these
data is needed in order to make commercial use
cost effective. We have a commitment from a
private company in the field of urban planning
photogrammetry to commercialize applications
resulting from this study for a transition from
conventional aerial photogrammetry, and for
increasing the use of data acquired by aircraft.

Project Title: Station-Keeping, Ocean Observing Terminus (SKOOTER)
Technical Abstract (Limit 200 words)
This SBIR Phase-I project combines the aerospace expertise of Jackson and Tull (J&T) in satellite communications and advanced data systems technology with the oceanographic expertise of Woods Hold Oceanographic Institution (WHOI) to design a Station-Keeping, Ocean Observing Terminus (SKOOTER) buoy. SKOOTER features an end-to-end command and data link between the oceanographic researcher's desktop computer and the remotely programmable, relocatable buoy. Wind- and solar-energy power both instrumentation and the propulsion system which SKOOTER uses to keep station. Remote programming allows its data-collection program to be altered in response to changing conditions; mobility and GPS for location information allows the SKOOTER to be programmed to move to new observing stations. The design will build on innovations developed by the J&T/WHOI team for its Modular Offshore Data Acquisition System, a 1995 NASA STTR project, and from its Nomadic Exploration Marine Observatory (NEMO), a 1996 NASA SBIR project, including an autonomous data system and two-way satellite communication system. The output of the Phase-I effort will be a conceptual design along with a numerical model that describes the horizontal motion of SKOOTER in response to wind, waves, and current, thus defining its practical regions of use.
Potential Commercial Applications (Limit 200 words)
The SKOOTER buoy will fill a need in the oceanographic community for an inexpensive alternative to moored buoys for long-term observations in remote, deep-water regions of the ocean. SKOOTER will be very easy to deploy, be much smaller, and have no mooring resulting in a much less expensive platform that performs most of the functions of the moored buoys with some significant advantages. Our buoy system will incorporate two-way satellite communications, advanced data systems, and be able to move to new locations on command. Taken together, these features add up to a breakthrough in buoy technology. With the same budgets, researchers will be able to put more buoys in the water while significantly increasing control over data collection.

Project Title: Scaleable UAV Navigator
Technical Abstract (Limit 200 words)
The Global Positioning System (GPS) is making low-cost navigation
accessible to aviation users as never before. In addition to area navigation, low-cost sensors for flight control and payload instruments are possible. However, while GPS makes these low-cost sensors possible, GPS does not fulfill the requirements alone. Area navigation needs continuity and integrity; flight control and payload need high bandwidth and attitude measurements. High bandwidth, continuity and attitude measurements are qualities which fall naturally into the performance characteristics of an Inertial Navigation System (INS). Unfortunately, navigation-grade INSs developed for airline and military use are currently priced in the $50,000 range and above, making them unaffordable for low-cost Uninhabited Aerospace Vehicle (UAV) applications. It is the combination of GPS with lower-grade INS that makes both low-cost and high-performance simultaneously possible. Our innovation is a low- cost, high-performance GPS/INS navigator that has low power requirements, is UAV-mountable, and is scaleable in both performance and functionality. Our navigator can provide (i) position, velocity and attitude for the UAV flight control and autonomous flight, and (ii) position, pointing information and precise time for payload purposes, such as measurement tagging.
Potential Commercial Applications (Limit 200 words)
Our low-cost, high-performance scaleable UAV navigator has a variety of applications including: (1) Low-cost UAV scientific and commercial applications, such as earth resources, high altitude atmospheric research, forest fire fighting and spotting, natural disaster management, large search and rescue missions (such as rescues at sea), aerial mapping, and severe weather penetration (hurricane studies); (2) Robust fault-tolerant approach-certified GPS/INS unit for General Aviation and Corporate Aviation use; (3) A low-cost GPS/INS attitude and heading reference system (AHARS) for autopilot systems for General and Corporate Aviation; (4) A reduced-order GPS/INS navigator for low-cost land vehicle navigation.

Project Title: Lightweight Deployable Antenna Structure
Technical Abstract (Limit 200 words)
Achieving a smaller stowed volume for antennas can be achieved by folding or rolling the reflector surface for the launch configuration. This study contract will define and evaluate designs which integrate existing technology of rigid, lightweight, composite reflector structure designs with flexible (unfurlable) surfaces and/or deployment hinge hardware/technology. The end goal is a deployable reflector design that has small stowed volume that maintains very precise surface dimensions. Currently, reflector designs are typically "rigid" sandwich structures made from aluminum or composites. This study will develop designs which overcome difficulty of maintaining precise surface dimensions after deployment. Our hinged concept design(s) will address precision installation of hinge hardware at surface section joints, and define compatible interfacing materials with respect to stiffness and thermal expansion. Our flexible/unfurlable skin design will ensure the proper deployed contours are achieved and no undesired plastic deformation occurs while stowed. The resulting design(s) will yield an antenna reflector that is lightweight, precise dimensional tolerance, small stowed volume, high stiffness, dimensionally stable and low cost. One design concept may be more suitable for the largest of apertures while another may be better for or higher frequency applications deploying moderately sized apertures on smaller launch vehicles.
Potential Commercial Applications (Limit 200 words)
A demand for large lightweight deployable space based antenna apertures has existed for many years. The need for these apertures is expected to increase in the future. Many of these future apertures will be at high frequencies and will be required to fit within a small launch volume. Current aperture technologies will drive the satellite's launch volume. The shrinking government budgets, as well as commercial requirements, may not tolerate the costs associated with the technology that is currently being used. In recent years, considerable progress has been made toward the design and fabrication of lightweight antennas from Polymer Matrix Composite (PMC) Materials. These antennas are approximately one half the weight of conventional lightweighted aluminum designs. However, additional development is required to provide even lighter structures which will meet the requirements of future military, science and commercial systems. COI has identified several new materials, design concepts and manufacturing approaches that offer a genuine opportunity to move these lightweight PMC antennas into future space systems. Our proposed Phase I SBIR program is an important step in the development and implementation of these technologies.

Inflatable Spacecraft Using
"Rigidization On
Command"Technology
Technical Abstract (Limit 200 words)
NASA, DoD and the commercial sector have a
rapidly growing need for large-scale and low-cost
inflatable spacecraft with high reliability. The
principal need for this technology is in the area of
high-frequency space communications. This
proposal represents new thinking in the area of
spacecraft materials and systems and is intended to
evaluate the unique "Rigidization On Command"
(ROC) technology. This proprietary chemistry uses
photocurable epoxy resins as a means to build the
rigid structural components of inflatable spacecraft.
These unique polymers solve a great many
problems currently associated with inflatable
spacecraft. Their use results in elimination of
rubber/fabric instabilities, rigidization when
required ("Rigidization On Command"), predictable
behavior, improved mechanical properties, and
indefinitely long storage life. The rigidization
process is initiated by simply switching on a
low-power ultraviolet light. The use of photocurable
epoxy technology permits deployable structures to
be fabricated that have low thermal mass, high
stiffness-to-weight ratios and considerable
reduction in overall mission risk. Low cost and ease
of fabrication also make this technology an
attractive candidate for new classes of very large
inflatable structures.
Potential Commercial Applications (Limit 200 words)
The commercial applications of inflatable
spacecraft are numerous, but concentrate on the
space deployment of very large antennas for the
purposes of Synthetic Aperture Radar (SAR), and
military and commercial communication systems.
Low-cost, pre-fabricated systems with indefinite
shelf life and immediate launch capability have
significant commercial potential in these sectors.

Autonomous Unified Orbit and Attitude
Control for Formation Flying using GPS
and LQG/LTR Controller
Technical Abstract (Limit 200 words)
This proposal provides an approach to the problem
of autonomous orbit and attitude control of
satellites flying in formation. In this approach, the
GPS data will be used for autonomous real-time
estimation and closed-loop on-board feedback
control of both the satellite orbit and attitude. While
existing literature show some progress on modeling
of formation flying dynamics with control law based
on nearest neighbor-tracking, the implementation
details of such control, including the method of
obtaining necessary observational information for
implementation have not been solved. Additionally,
the control system proposed here not only
maintains the formation pattern using GPS code
pseudorange data, but also provides the attitude
determination and control using GPS differential
phase pseudorange. Because attitude dynamics and
kinematics equations are nonlinear, one of the
innovations being proposed is application of
nonlinear control technique to solve the nonlinear
feedback problem. The additional innovation is the
unified architecture for orbti and attitude control
system. This topic is in direct response to NASA
GSFC's specific interest in advanced formation
flying for its 'Mission to Planet Earth' Guidance,
Navigation and Control need of the future.
Potential Commercial Applications (Limit 200 words)
With commercial communication satellite operators
shifting their attention to low-earth orbit satellites,
opportunities are opening up for commercial
application of designs involving autonomous
on-board orbit and attitude control systems. While
initial efforts are on constellation operations,
formation flying is of potential interest to these
operators because of their inherent advantages in
providing precise patterns and advantages such as
in providing 'virtual aperture' and similar advanced
techniques. There is also potential application of
formation flying to geostationary communication
satellite operations. With increasing number of
satellites vying for shrinking number of available
geostationary slots, multiple satellites are being
station-kept within the same stationkeeping box
using the techniques of co-location. These
collocation methods involve phasing the eccentricity
and inclination vectors of the satellite orbits to
provide sufficient spatial separation between
satellites. However, there is enough uncertainty
and inaccuracy in the current methods to warrant
implementation of formation flying for co-location.
Formation flying will also enable co-location of a
much larger number of satellites than is currently
feasible.

Computer-Aided Engineering (CAE) tool
for the evaluation of Mission to Planet
Earth Satellite guidance, navigation, and
control (GN&C) performance.
Technical Abstract (Limit 200 words)
Illgen Simulation Technologies, Inc. (ISTI)
proposes a computer-aided engineering (CAE) tool
that directly supports the development and
validation of Global Positioning System
(GPS)-based approaches to space-based guidance,
navigation, and control (GN&C). Model innovation
includes the application of Wide Area
Augmentation System (WAAS) signals to
space-based GN&C and the development of
space-based receiver and accelerometer
simulations.
ISTI proposes to enhance its current simulation
(iWAASs) of the Federal Aviation Administration's
(FAA) Wide Area Augmentation System (WAAS) to
include:
1. Development and demonstration of prototype
WAAS messages,
2. Development and demonstration of a
space-based WAAS/GPS receiver model for
determination of platform dynamics and orientation.
Together with the current capabilities of iWAASs,
these added features will address the key risk
areas in the development of an integrated
computer-aided engineering (CAE) tool for the
modeling and assessment of Global Positioning
System (GPS) based guidance, navigation, and
control (GN&C) processes for satellites in the
Mission to Planet Earth program or other space
platforms.
Potential Commercial Applications (Limit 200 words)
Use of WAAS-augmented GPS signals for
determination of space-based platform dynamics
and orientation is a promising and attractive
alternative to traditional GN&C techniques,
particularly because the GPS/WAAS approach
provides the basis for high-precision determination
and control of these parameters on-board the
satellite. A commercial CAE tool for design,
modeling, and assessment of GPS/WAAS-based
GN&C systems performance would be of interest
for satellite system design, mission planning,
mission operations, and performance assessment of
satellites using this technique.

Project Title: Radiation Hard CMOS APS Circuits for Star Trackers
Technical Abstract (Limit 200 words)
It is proposed to develop key circuit components for a radiation-hard active pixel sensor (APS). Specifically, we propose to develop and model radiation-hard complementary metal-oxide-semiconductor (CMOS) APS circuits optimized for use in spacecraft microstar and feature tracker applications. APS image sensors enable true micro-star and feature trackers by providing a highly integrated, ultra-low power camera-on-a-chip solution. Radiation induced damage in solid state image sensors leads to degraded sensor performance, consequently reducing the capability and accuracy of the tracker. However, APS circuit designs may directly draw on the large base of experience and techniques used in the solid-state device industry to create radiation-hard CMOS devices (e.g. memory and Infrared focal plane multiplexers). We will study and model key radiation-hardening techniques used in the CMOS design community, leading to innovative, radiation-hard APS circuit designs. The innovation of these APS circuits greatly enhances the survivability of micro-trackers over a much wider range of radiation hazards and space missions than currently possible. The proposed radiation-hard sensor circuits offers NASA unprecedented image sensor functionality and dramatically increased system robustness.
Potential Commercial Applications (Limit 200 words)
The APS circuits proposed in this effort are applicable to micro-star and feature trackers as well as other science and defense spacecraft instrumentation. Practically all terrestial high radiation environments needing video monitoring will benefit from a radiation-hard APS array. These include a wide range of medical imaging and diagnostic systems, cameras for nuclear power plants, and radiation waste management operations.

Project Title:
Low Cost Beaconless Laser Search and
Rescue System
Technical Abstract (Limit 200 words)
A new beaconless technique for search and rescue
is proposed that promises to be simpler and more
cost-effective than existing techniques. This new
technique incorporates a laser scanner instrument
and unique passive retroreflector markers attached
to aircraft and watercraft to accomplish detection in
the presence of glint and other background
reflections with a very low false alarm rate. It will
permit rapidly searching large areas in daylight or
night conditions. The new technique builds upon the
experience gained from a similar LASAR (LAser
Search And Rescue) technique, now in the
prototype testing stage, but utilizes simpler and
lower cost system components than the existing
technique. These simplifications would result in
reductions in the instrument size, weight, and power
requirements. This smaller, lower cost, instrument
could be installed onto light aircraft such as the
Cessna-172 used by the Civil Air Patrol (CAP) or
the HH55 helicopter used by the U.S. Coast Guard
(USCG). The proposed work will determine the
feasibility of the new technique through
experiments conducted using the existing prototype
laser scanner system (LASAR) developed by
Daedalus. The feasibility test results will be
analyzed with regard to the requirements of typical
CAP and USCG search and rescue scenarios.
Potential Commercial Applications (Limit 200 words)
A large international market exists for instruments
to assist in the search and rescue operations for
survivors of airplane crashes and boat accidents.
The high failure rate and high false alarm rate
caused by unintentional activation of emergency
radio beacons have produced a need for an
alternative means of improving search and rescue
operations. The proposed laser search and rescue
technique offers a cost-effective alternative to
emergency radio beacons. A commercial market
will exist in the United States provided that the U.S.
government mandates are established to require
the installation of air and watercraft retroreflector
markers and government agencies commit to the
use of the instrument on search and rescue aircraft.
It is estimated that those mandates and
commitments would result in a worldwide market
for more than 340 instruments and over 7,000,000
square feet of retroreflector material.

Nonlinear Dynamical Techniques for
Analyzing Spacecraft Data
Technical Abstract (Limit 200 words)
This projet will study the feasibility of near
real-time analysis of spacecraft data for
characterizing complexity in images and for
prediction. Nonlinear dynamical techniques have
the ability to recognize the structures and their
dynamical evolution, independent of a priori
assumptions, thus capturing the essential features
inherent in the data. Models of the near-Earth
geospace developed with these techniques have
given good predictions of the global dynamics and
the capability to incorporate the extensive
information contained in the images obtained by
orbiting spacecraft need to be developed. The
proposed research will develop tools for using
spacecraft data for real-time or near real-time
predictions of space environment, and for
characterizing complexity in images. The focus is on
the development of interactive tools for extracting
the leading features in large data bases, in paricular
satellite images. These tools will be developed in
object oriented graphical programming language
such for use in on-line browsing and computation of
leading features. At the conclusion of the Phase I
effort a proto-type tool for on-line analysis of
complexity or patterns in images and prediction of
the space environment, and the feasibility of
commercialization report will be provided.
Potential Commercial Applications (Limit 200 words)
The rapidly escalating size of space borne data such
as images undescore the need to extract the leading
features from these large volume data sets.
Innovative techniques for characterizing the trends
and patterns in such data bases are expected to
have extensive applications and commerial
potential. Further, the predicting ability of these
techniques will yield reliable and accurate
forecasting tools for space weather, which has
become essential due to the increasing economic
use of outer space and the increasing complexity of
the technology base such as electric power and
telecommunication systems.

Remote Sensing Enhancement of
Shallow Water Bathymetry
Technical Abstract (Limit 200 words)
The littoral environment is characterized by
complex bathymetry and current systems that
constantly evolve in response to storms and human
intervention. Consequently, coastal morphology is
poorly known in many regions or represents old
data in others. Yet, coastal bathymetry is important
to land management, hazard assessment and
mitigation, and many military operations. Pacific
Sierra-Research (PSR) proposes a fusion approach
to multispectral (MS) optical and SAR imagery to
enhance low-resolution coastal bathymetry or to
update old surveys. Each provides a different
spatial picture of the bathymetry; MS provides a
very high resolution picture while SAR provides a
hydrodynamically filtered picture. The fusion of the
two, especially in an area where low resolution
bathymetry is available, reduces the impact of
unknown optical and meteorological parameters
while providing a high resolution bathymetric
mapping capability. The approach takes full
advantage of the physics of differential optical
attenuation in seawater, and seasurface roughness
perturbation scattering to optimally utilize the
strengths of each sensor. A neural network
approach to rapidly estimate SAR surface
scattering results in a high speed algorithm. This
neural network approach greatly extends current
capabilities to interpret SAR imagery in terms of
shallow water bathymetry and provides a means for
rapid mapping.
Potential Commercial Applications (Limit 200 words)
Rapid bathymetric mapping in coastal regions is
key to understanding the littoral environment, and
human impact upon it. Rapidly mapping is required
to evaluate the near-term effects of natural
disasters on the littoral environment. The proposed
software merges information from two of the best
remote sensors to provide new bathymetric
information. The algorithms can be directly used by
the developing remote sensing industry or by
individual users or researchers with access to
imagery. If successful, coastal cities, planner, and
relief organizations will have need of the code or
bathymetric results.

Project Title:
Open-Cell Silicon Foam for
Ultralightweight Mirrors
Technical Abstract (Limit 200 words)
The Next Generation Space Telescope (NGST) will
require large optics that are superior in many
respects to those of the Hubble Space Telescope
(HST). In particular, the NGST will require a larger
primary optic, lower mass, usability over a greater
range of temperatures (as low as 20 K), and greater
thermal stability. Whereas many of the features of
the HST resulted from "brute force" engineering,
the goal of the NGST is to use a more elegant
design to achieve extremely ambitious optical
goals. The most significant technical challenge in
producing components for the NGST will be
reducing the areal density of the primary optic. The
feasibility of using open-cell silicon foam mirror
support structures combined with silicon facesheets
has been demonstrated at Ultramet, and areal
densities as low as 11 kg/m2 have been achieved.
Manufacture of the silicon foam, however, is
presently a time-consuming process. In the
proposed project, Ultramet will develop an
innovative process for manufacturing open-cell
silicon foam for use in lightweight silicon mirrors.
Potential Commercial Applications (Limit 200 words)
The commercial applications for lightweight silicon
mirrors are numerous, but the primary near-term
goal is to supply the primary optic of the NGST.
Other applications that would benefit from this
technology include all mirror applications in which
weight and/or athermal behavior is critical, such as
fast steering mirrors, uncooled laser optics, and the
space-based laser. The proposed silicon foam
fabrication route is an enabling technology for the
silicon foam mirror support structure required by
these applications.

Integrated Design and Optimization of
Thermal/Structural/Optical Systems
Technical Abstract (Limit 200 words)
Without an ability to share design tools, the
disciplines of thermal control, structures, and optics
levy worst-case performance requirements on each
other such that each specialty can contribute to a
design independently. This results in a stack-up of
margins and inevitably to over-design to the point
of rendering advance missions such as the NGST,
with its cryogenic large aperature optics, difficult to
achieve without an integrated design approach. For
example, temperature gradients in a mirror support
structure are inconsequential as long as the
required optical performance is achieved, yet
derived limits on such gradients often become a
design driver for thermal control specialists.
Recent innovations by the proposed development
team have eliminated many of the stumbling blocks
that stymied previous attempts to achieve a tight
integration between thermal control, structures, and
optics. These advances include a finite
element-compatible thermal radiation analyzer,
thermal tools compatible with CAD databases,
optimizing thermal/fluid solvers, and integrated
structures/optics design and optimization. It is now
possible to achieve not only an integrated tool suite,
but also one that can automatically find the
mimimum mass design that meets required optical
performance under all structural load cases and
thermal environments. Revolutionary designs are
expected from a revolution in the design process.
Potential Commercial Applications (Limit 200 words)
The demand for high-performance designs with
tight alignment requirements is not limited to
optical systems. Mortorola's next-generation
Iridium project, for example, is expected to employ
a small phased-array antenna with over 6kW of
dissipation and little tolerance for deflections. This
and other commerical demands for high-level
design optimization tools will assure the
commercialization of the resulting software,
including the results of the Phase I project.

Deformable Mirror Multiplexer Driver
Electronics
Technical Abstract (Limit 200 words)
For spaced-based adaptive-optics systems the
deformable mirror must be small, rugged, and
lightweight while still delivering stroke and
accuracy exceeding ground-based systems. To that
end, Xinetic's work on high-density deformable
mirrors under a Phase I SBIR demonstrated that
mirrors suitable to these requirments can be built.
The deformable mirror represents only half of a
total system, however. The driver electronics must
also deliver high-accuracy in a small package
suitable for satellite applications. Current driver
systems fill a 7' rack, weigh over 400 pounds, and
dissipate multiple kW's of heat for a 349-channel
system. For the 16,000 channel systems envisioned
for NGST we need much lower frequency response
but they must be highly efficient designs. To satisfy
these requirements Xinetics proposes a digital
multiplexer driver system. By taking advantage of
the unique dielectric characteristics of the Xinetics
PMN actuators and digital multiplexer circuits we
can generate a small, high efficiency electronic
system which can fit in a single chassis. The
multiplexer will use a single amplifier channel along
with a digital switching system to send commands to
the individual actuators in a raster mode. In this
way hundreds or even thousands of channels may
be contained on a single driver board.

Project Title: Fully Active Scale Telescope (FAST)
Technical Abstract (Limit 200 words)
In this Phase I SBIR research project Blue Line Engineering will design a fully active 1/8th scale replica of the current NASA baseline for the NGST mission. This scale telescope will serve as an optically correct model of the full scale 8 meter version. The novelty of the proposed project is that it leads to an extremely useful and versatile asset for the NGST program. The main purpose of the telescope is to serve as a reality check and validation for computer models and simulations of control systems for the active primary mirror. Control algorithms may be implemented on the telescope with little modification. The scale telescope can also function as a fieldable 1 meter astronomical telescope with active figure control. It will feature hinged mirror petals and a deployable secondary as in the NGST baseline. This will allow the telescope to be stowed in a compact configuration for transport to NASA meetings and reviews. By packaging what is primarily a functional testbed as what appears to be a reasonably detailed model of the NGST telescope, we will provide NASA with a very powerful tool for the dual challenges of developing control algorithms and winning public support.
Potential Commercial Applications (Limit 200 words)
One commercial application we have identified at this time is to offer a limited edition of these telescopes for sale as high-end collector's items for connoisseurs and serious amateur astronomers.

Project Title: Low Current HTS Coils for High Temperature Superconducting Actuators
Technical Abstract (Limit 200 words)
American Superconductor Corporation proposes the development of a high strength, high current density, low heat leak HTS wire directly suited to the construction of cryogenic actuators for a variety of space applications, including the Next Generation Space Telescope (NGST). The proposed innovation consists of evolving present HTS conductor technology, which has been developed for high current electric utility applications, to produce a HTS conductor suitable for spacecraft applications. To date, no fully suitable cryogenic optical actuator technology has been demonstrated. Fundamental materials issues argue against using the customary piezoelectric actuators at low temperatures. However, he Jet Propulsion Laboratory (JPL) has recently demonstrated small scale magnetostrictive devices operating at cryogenic temperatures that provide the building blocks for the required actuators. These devices used large cross section HTS conductor and required operating currents larger than those practical on a spacecraft. The proposed program would develop the conductor required for low current, low power operation.
Potential Commercial Applications (Limit 200 words)
The work proposed under this grant will advance the state of the art of HTS conductor design and manufacture and address the issues of increasing current density and reducing the conductor's cross-sectional area. Advances in this area of conductor design are required for the development of commercial HTS applications, including cryogenic actuators, cryogen flow valves, mechanical heat switches, IR spectrometer tuning actuators, vibration isolation actuators, linear actuators and generic space-based applications that would benefit from HTS coils, partularly those employing passive cooling.

Project Title: Multidither Sensing for Wavefront Control
Technical Abstract (Limit 200 words)
Attractive concepts for space-based telescopes with large apertures include thin stiffened membranes and assemblies of lightweight mirror segments. Either may be quite stable at rest, but disturbances can produce small distortions that would degrade optical performance if uncorrected, and means must be provided to accurately sense and position to the tolerances required for phase coherence. Hartmann sensing or shearing interferometry have generally been used in the past with ground-based adaptive optics systems, and phase retrieval techniques have recently been proposed for NASA?s NGST program, but all require a relatively bright distant object, the first two effectively measure the local tilt instead of the displacement itself, all require intensive computations to produce the needed result, and phase retrieval may not converge to the correct result. Unlike those techniques which seek to determine and then to correct the wavefront, this proposal is based on the all-but-forgotten "multidither" approach that unambiguously maximizes the intensity of the image itself by individually "tagging" corrective elements with small high-frequency piston oscillations and then adjusting those segments until those frequency components vanish. Sirius proposes to resurrect this promising technique, using high-speed electronics, logic, and detectors to overcome its early faults and to exploit its strengths.
Potential Commercial Applications (Limit 200 words)
Multidither sensing for wavefront correction promises the use of commercially available components and relatively simple electronic hardware, it does not require a separate "beacon" as a reference source, and it provides an unambiguous solution for maximizing intensity in the focal plane. As such, it offers significant economic and performance benefits to the astronomical community, ranging from very large space-based telescopes to the amateur community, and to the potentially massive communications industry for both ground-based receivers and laser transmitters.

Project Title: An Inchworm Actuator For The Next Generation Space Telescope
Technical Abstract (Limit 200 words)
A new NGST Inchwormâ motor is proposed that meets the demanding actuator requirements of the Next Generation Space Telescope. Burleigh?s current Inchworm motors do not function at cryogenic temperatures. The interference fit between the motor and shaft gets tighter and breaks the clamps and 80 percent of piezoelectric (PZT) motion is lost at 30 K. Burleigh?s NGST Inchworm concept maintains a constant fit over a wide temperature range and the loss of PZT motion is compensated for by adding extra PZT material or potentially by incorporating new cryogenic active materials that are currently being developed by other companies. Another significant improvement of the NGST Inchworm is the ability to hold position when power is removed (i.e. zero charge on all actuators) with zero PZT creep. This makes it possible for the NGST Inchworm and electronics to dissipate zero power when holding position for days or weeks. The NGST Inchworm will have a new clamp design that has at least ten times lower "clamp glitch" than today?s Inchworm. Low clamp glitch makes it possible to move to a desired position with nanometer resolution and deactivated the motor without disturbing the output position more than 2 nanometers.
Potential Commercial Applications (Limit 200 words)
A significant commercial market is spaced-based telescopes and other spacecraft that need to operate over wide temperature ranges. The ground-based market also has significant potential. Burleigh's marketing and sales force consistently receives requests from scientists around the world who need Inchworm performance at liquid Nitrogen or liquid Helium temperatures to study materials and surfaces. This new technology will also help expand Burleigh?s non-cryogenic Inchworm sales in numerous applications because it is self-locking when power is removed, has very low glitch, and higher reliability.

Sputtering Silicon Coatings for Large
Aperture (2 meter) Silicon Carbide
Optical Segments
Technical Abstract (Limit 200 words)
Silicon Carbide (SiC) optics have been identified as
a key technology for several NASA missions
including Next Generation Space Telescope
(NGST). SiC has superior thermal stability and
excellent specific stiffness making it ideal for space
based optical systems. NGST requires SiC optical
segments which are both lightweighted and large
(1-2 meter segment sizes). Polishing these large SiC
segments pre- sents a number of problems; the
pieces are very thin and cannot with- stand large
polishing pressures. Flat or spherical optical
surfaces can be obtained directly on SiC materials
using conventional polishing systems. The problem
has been in obtaining non-symmetric aspheric
surface profiles in the hard SiC material. A common
solution has been to coat SiC optics with a thick
cladding (0.005") of silicon. The silicon can be
easily polished with moderate pressures and the
coefficient of thermal expansion (CTE) match
between SiC and silicon is very good. SSG has
extensive experience in the silicon coating of SiC
optics. In order to make the process feasible for a
program like NGST a number of technical issues
need to be addressed: (1) the sputtered silicon
coating process needs to be modified to eliminate
coating stresses and make silicon coatings suitable
for very thin, lightweighted SiC optical substrates;
(2) the metrology associated with the SiC substrate
machining needs to be improved to minimize the
amount of silicon needed in the cladding; (3) a
large-scale coating facility needs to be developed;
and (4) the current process needs to be modified to
address the uniformity requirements associated
with large scale optical segments. The proposed
Phase I work will address all these issues. During
Phase I a large sputtering chamber with a 2-meter
capacity will be brought on-line and the viability of
the processes proposed will be demonstrated with a
number of sub-scale empirical demonstrations.
Potential Commercial Applications (Limit 200 words)
The NGST application alone represents an
important Phase III application. The development
of the unique large-scale, sputtered coating
capability will also make the development of large
aperture (1-2 meter diameter), ultralightweighted
SiC optical systems viable for a number of NASA,
DoD, and commercial applications.

Project Title:
Starlight Fringe Detection and Tracking
Algorithms for Long-Baseline Space
Based Interferometers
Technical Abstract (Limit 200 words)
The goal of this SBIR Phase I project is to
demonstrate the feasibility of using advanced
nonlinear estimation algorithms as practical design
solutions to the challenge of micro-arcsecond
precision starlight fringe detection and tracking
with the first generation long-baseline, space-based
interferometers (e.g., the Space Interferometry
Mission, SIM), exhibiting long, flexible truss
structures excited by dynamical disturbances. This
goal is responsive to the topic on Space Based
Optical Interferometers, sub-topic on Metrology
and Starlight Detection System. The proposed
objectives to achieve this goal are: the development
of a truth model simulation incorporating structural
dynamics for SIM as focus mission; the
implementation and evaluation of state-of-the-art
tracking algorithms for comparison purposes; and,
the development, implementation, testing and
evaluation of new nonlinear fringe tracking
algorithms.
The use of the best tracking algorithms will reduce
mission costs through more relaxed hardware
requirements; and maximize scientific results
through faster tracking of bright stars and the
tracking of the dimmest stars. As a result of this
SBIR effort, we anticipate a software product
consisting of a core suite of high-performing
algorithms together with a simulation shell that will
enable researchers to project all design decisions
onto the ultimate measure of performance: the
astrometric accuracy.
Potential Commercial Applications (Limit 200 words)
The resulting software product will be invaluable for
current and planned, space- and ground-based
interferometric arrays world-wide, both military and
scientific. This technology will also be of use for
industrial interferometric metrology applications
such as the teseting of precision optical surfaces
and the precision motion control of systems for
nano-technology applications (e.g., semi-conductor
manufacturing).

Project Title: Low Noise/Thermal Signature Electronics for Precision Space Interferometry
Technical Abstract (Limit 200 words)
Long baseline interferometric astronomy offers higher angular resolution than is possible with conventional telescope techniques. However, one of the major challenges to realizing interferometry is maintenance of structural rigidity in terms of pathlength control and tilt control. A promising approach under exploration at NASA is the use of the new generation of induced strain actuators which meet crucial adaptive optic and precision alignment needs. Switching technologies are particularly attractive as drive mechanisms due to payload reduction and low thermal signature characteristics. However, although attractive for space astrophysics missions such as SIM, existing switching designs have unacceptable high frequency radiated and conducted edge-triggered noise effects. The proposed advanced regenerative polyphase electronics would provide an innovative solution to excessive noise and thermal radiation levels in electronic subsystems needed for space interferometry.
Potential Commercial Applications (Limit 200 words)
Many applications of active ferroelectrics to commercial products are noise and thermal rediation level critical. Advanced regenerative polyphase electronics technology would facilitate their market introduction. The ability of lightweight, regenerative electronics, operating with up to 94% efficiency, has attracted significant interest from commercial users including TRW, Boeing, Cessna, Burleigh Instruments, SSG, ACX, BBN and others.
EMF is establishing strategic partnerships with, among others, TRW for satellite applications, Cessna for light aircraft, Quiet Power for electric power transformer quieting applications, Blatek for ultrasonic cleaning of semiconductor wafer applications, BBN for turbine engine quieting applications and MSI/TRS Ceramics for sonar applications. All these products would be beneficiaries of the proposed research. However, it is in the application to active optics and communication systems for military and commercial satellites that the reduction in thermal and noise signature could provide the greatest benefit.

Project Title: Light-Weight, Low-Power, Thermally Stable, Large-Field-of-Regard High-Accuracy Gimbal
Technical Abstract (Limit 200 words)
The proposed innovation applies to thermally stable, large-field-of-regard, high-accuracy gimbal technology for NASA interferometer applications such as SIM, NMI, SITE and ISIS. The classical approach is a solid ULE mirror in a mirror cell suspended in an external gimbal ring with actuators located outside the mirror?s perimeter. The moving elements weigh 46.5 kg and the whole mechanism weighs 63.4 kg. The proposed innovation allows direct attachment of flexure and actuator assemblies to a lightweighted mirror substrate via five INVAR backplates bonded to the mirror?s ribs to maintain 1/100 wave RMS surface quality over a +-30 degC temperature range. The attachment technique minimizes and isolates forces and torques due to attachment and CTE mismatches from the first surface. The combination of light-weighting and backplate attachment reduces the mass of the mirror by 65%, eliminates the mirror cell and external gimbal ring and reduces the footprint of the suspension and actuators for a smaller, lighter support structure. The total weight savings is more than 30 kg. It also increases suspension lateral load capability by a factor of 2, reduces heat dissipation at the actuators by more than 90% and allows operation at higher control bandwidths.
Potential Commercial Applications (Limit 200 words)
Primary applications are interferometric missions for NASA and other advanced astrometrics, including SITE, SIM, NME and ISIS. This technology would also be an improvement for airborne infra-red observatories similar to SIRTF and OAMP which require light steering mirrors with high optical quality.

Project Title: Self-contained Autonomous Vibration Control Actuator
NASA's development of large high precision
spacecraft for future interferometry missions will require extensive use of active control to quiet vibration of the structure supporting the measurement instruments. To date, such control systems have been unattractive to spacecraft designers because of their complex interfaces, inability to accommodate system changes, and high cost of design and verification. We propose to prove the feasibility of a completely autonomous vibration control actuator which requires only a connection for power and enable input. Design of the autonomous vibration control actuator is made possible by a novel adaptive control algorithm which is computationally simple and uses only a local measurement, and the high-bandwidth and linearity of our patented Linear Precision Actuator (LPACT). The new actuator design incorporates a chassis mounted accelerometer and an integral onboard electronics package. This package houses an amplifier to drive the actuator and a processor to execute the adaptive algorithm. This algorithm uses the accelerometer measurement to learn the dynamic characteristics of the structure to which the actuator is mounted (even adapting to changes in these dynamics), derives a vibration canceling control, and commands the actuator to exert vibration canceling forces.
Potential Commercial Applications (Limit 200 words)
The specific product that will be developed with this SBIR effort is a fully adaptive, autonomous vibration control actuator which requires only connections for power and an enable input. Its simple mechanical interface provides ease of retrofit to existing structures, and its simple electronic interface and self teach ability minimize the impact of applying the actuator to a new or existing structural design. This product can be applied to a wide array of structural control problems including: large lightly damped space structures, quieting of high precision measurement systems, semiconductor manufacturing, and optical systems. Initial development will focus on high-valued systems such as spacecraft where there is a large financial incentive for vibration reduction.

Project Title:
Super Accuracy Locking and Self
Actuating Hinge Joint
Technical Abstract (Limit 200 words)
Future, large aperture space science missions such
as the Space Interferometry Mission and the Next
Generation Space Telescope will require large
mirrors and structures to be deployed with optical
precision. Current technologies require complex
drive mechanisms and latches that have intricate
contact mechanisms that have been experimentally
shown to make the structures inaccurate and their
behavior difficult to predict.
Foster-Miller is proposing a joint that is based on
the innovative combination of curved and flat
flexures. The joint provides 180 degrees of rotation
by elasticly bending unique sets of flexures. Once
the joint unfolds to its final position, the curved
flexures lock into a rigid, post-buckling state. In
addition to acting as a hinge and a lock to fix the
structure rigidly into position, the stored strain
energy in the joint's folded state provides the
actuation torque required to deploy the spacecraft
structure or instrument. Since the joint's flexures
are bonded in place, it is a monolith, giving it
sub-nanometer linearity and precision.
The monolithic, sub-nanometer accuracy joint would
provide future NASA deployed science instruments
with a single hinge, lock and actuation component
that would have optical performance and be
completely ground verifiable.
Potential Commercial Applications (Limit 200 words)
The super accuracy, locking and self actuating
hinge acts as a key component in a deployed
instrument and replaces traditional actuation and
lock mechanisms with a single, light weight, low cost
component, thus it is ideal for all deployed
structures as well as optical instruments. By
replacing actuation and locking mechanisms, the
joint would reduce the cost and weight of all
deployed components of commercial spacecraft
such as solar arrays, thermal radiators and heat
shields.
For terrestrial applications, the low cost and
strength of the joint make it a cost effective
component of rapidly erected structures such as
tents, emergency shelters, and police barricades.

Project Title: Active-Passive Precision Electromagnetic Vibration Attenuation System
Technical Abstract (Limit 200 words)
A system for mechanically mounting vibration-producing or vibration-sensitive components to spacecraft is proposed. The vibration transmitted to and from the mounted components will be attenuated significantly by passive dissipative components and active suppression components combined in a single device. The temperature-insensitive and non-contaminating passive isolation is based on magnetic eddy current damping. Active suppression is achieved by electromagnetic reaction mass actuators. Mass penalties associated with magnetic technology are mitigated by the dual passive-active functionality of several components within the device. The active system is controlled with custom space-ready control system electronics. The entire attenuation system can also be used in conjunction with existing piezoelectric-based microprecision vibration isolation and pointing mounts to enhance vibration attenuation. The feasibility of this approach will be confirmed by analysis, design, and prototype test. The proposed research answers the stated need for vibration attenuation and isolation for ultra-quiet precision systems. NASA's interferometry missions, as well as other spacecraft, will benefit directly from the low vibration mounting system. Noisy components such as reaction wheels and cryocoolers can be upported by such a system to minimize disturbance of the rest of the spacecraft. Quiet instruments can be supported by separate platforms attached to a relatively noisier structure.
Potential Commercial Applications (Limit 200 words)
The technology has direct commercial application on-board low cost satellite busses that host imagers and laser communication instruments while using relatively noisy attitude control. There is immediate terrestrial application in vibration suppression enhancements to a microprecision vibration isolation product introduced recently for semiconductor manufacturing equipment.

Project Title: Novel Microchannel Plate Detector
Technical Abstract (Limit 200 words)
The purpose of this proposal is to develop new microchannel plate (MCP) detector technology for UV and x-ray radiation to support the NASA Structure and Evolution of the Universe mission. MCP are used in high speed, low light level photoelectron (UV-IR), x-ray, and particle (neutron, ion, electron, atom) imaging and detection. However, conventional Pb-glass based MCP suffer from: limited lifetime, relatively low temperature processing <450°C, intrinsic gain fluctuations from the Poisson statistics of the secondary emission in the first few channel gain collisions, cumulative spatial non-uniformities and channel-channel spatial gain variations from the intrinsic errors in the glass channel dimensions and array packing defects, limited particle fluxes due to the limited range of plate resistivities. NanoSystems, Inc (NSI) proposes to use NSI-developed silicon/silica photolithographically precise MCP substrates as the basis for a new large area MCP utilizing a novel negative electron affinity thin film coating which achieves both high secondary emission and controlled conductivity in a single uniform materials system, leading to: high gain and low single electron gain fluctuations, high temperature operation, long lifetime, high flux or low light level operation by controllable film resistivity, defect-free, high spatial resolution and spatial precision, and areal detection efficiency exceeding 90%.
Potential Commercial Applications (Limit 200 words)
The new MCP discussed in this proposal will lead to new applications in medical and industrial inspection imaging using x-rays, and particles as well as mproved night vision imaging with higher resolution and lower noise. The new NSI MCP fabrication capability permits much larger area precisely positioned channels and with appropriate readout circuitry are capable of imaging at extremely high speed with spatial resolution exceeding 100 lp/mm.

Project Title:
High Angular Resolution Thin Foil
X-ray Mirrors
Technical Abstract (Limit 200 words)
The innovation proposed by RJH Scientific, Inc.
(RJHS) is to increase by a factor of 4 to 10 the
angular resolution of current foil-based,
grazing-incidence x-ray telescope mirrors. While
thin foil mirrors have already been used
successfully to fabricate large effective area, light
weight x-ray mirrors, the angular resolution
achieved by these telescopes has typically been
limited to a few arcminutes. We propose to
demonstrate the feasibility of fabricating and
aligning thin foils with reduced surface roughness
and sufficiently low figure errors to produce x-ray
mirrors with angular resolution (defined as the half
power diameter) around 15 arcseconds. This
angular resolution, combined with the light weight
and efficiency of thin foil segmented mirrors, will be
ideal for advanced x-ray astronomy missions such
as the High Throughput X-ray Spectroscopy
(HTXS) Mission. Specifically, we intend to
accomplish the following tasks:
1. Demonstrate that we can reduce the surface
roughness of completed thin foils from current
typical values around 6 Angstroms RMS to about 3
Angstroms RMS;
2. Prove that thin foils can feasibly be fabricated
with sufficiently good optical figure to produce
images with about 15 arcsecond angular resolution;
and
3. Align the foils properly and maintain this
alignment despite mechanical and thermal stresses.
Potential Commercial Applications (Limit 200 words)
The immediate commercial potential of the
proposed research is the manufacturing of x-ray
mirrors for space-borne x-ray astronomy
instruments on future missions by NASA and other
space agencies. The primary commercial
opportunity based on results of the proposed
research will result from adapting the technology
for use in medical diagnostic x-ray instrumentation.
Thin foil, multilayer coated mirrors can be used to
create spectral filters which will produce nearly
monoenergetic x-ray beams with energies ranging
from less than 10 keV to approximately 50 keV.
The capability to select the optimal energy of the
x-ray beam simply by inserting the appropriate
filter module will improve the performance of
diagnostic x-ray imaging instruments used for
mammography, standard computed tomography,
and multiple energy computed tomography. Other
potential applications include enhancing x-ray
instruments used for industrial process inspection
and for security screening. For these applications,
as for medical imaging applications, adding narrow
bandpass x-ray filters to currently existing
broadband x-ray sources can improve both spatial
resolution and the ability to detect low-contrast
features.

Technical Abstract (Limit 200 words)
Hytec has conceived of an innovative structural and

gamma-ray (.01-100 Gev) tracking detector that will
measurably improve the resolution of detection
systems being pursued by NASA. We achieve a
compact, and passively cooled tower design through
an innovative approach to the structural design of a

into a tower configuration. Our concept offers a
means to reduce dead area between active tracking
regions, thus improving track reconstruction
efficiency and background rejection. By using
advanced composite materials, we achieve a low
mass structure, passively cooled tracking detector
with a high degree of temperature uniformity in the
silicon modules. Our design concept focuses on
minimizing structural mass in front of the
conversion layer to limit multiple scattering of
charged particles. The composite materials have a
high radiation length, second only to Beryllium, and
thus, further minimize multiple scattering.
Potential Commercial Applications (Limit 200 words)

Project Title: Light-Weight, Temperature-Insensitive, High-Precision NMR Magnet
Technical Abstract (Limit 200 words)
Nuclear magnetic resonance (NMR) is a well-known, powerful technique for detecting and identifying both inorganic and organic substances. Such a diagnostic may enable finding indications of life on remote bodies such as Mars. To do this requires an NMR system which is light-weight, has high precision, and is able to operate under the large temperature variations of the Martian surface. The magnets of conventional NMR systems are too large and heavy, and cannot tolerate large temperature extremes. We propose during Phase I to design a light-weight, self-temperature-compensating NMR magnet based upon a demonstration device, which we have already built. Our NMR magnet features uniform magnetic fields produced by permanent magnets. The design makes efficient use of the magnet, thereby reducing its size and weight. High field
precision is obtained using proprietary manufacturing and assembly techniques.
Self-temperature-compensation of the magnetic field also uses proprietary techniques. Measurements of selected components of the NMR magnet will also be performed during Phase I to verify the design parameters. Based upon the
Phase I design and measurements, a working prototype will be built during Phase II. This prototype will be capable of flying on a NASA satellite.
Potential Commercial Applications (Limit 200 words)
A compact NMR magnet would be an attractive alternative to current NMR magnets, which can be bulky in size and weight. It can also be used in new applications where the environment prevents using existing NMR devices. Examples are extreme temperature locations, such as the Antarctica; monitoring of in-line industrial processes, waste effluents, and water quality; and radioactive waste tanks.

Project Title: Detection and Measurement of Large Chiral Organic Molecules Using Molecular Imprinting (MI) Technology
Technical Abstract (Limit 200 words)
The need for robust, compact in situ sensors which are easily cleaned and do not introduce foreign biological materials is a must for planetary exploration. Systems & Processes Engineering Corporation (SPEC) and Dr. J.P. Chambers of University of Texas at San Antonio propose to use molecular imprinting (MI) technology to fabricate artificial receptors for detection and measurement of large chiral organic molecules. The MI technology will provide a means of developing non-biological based receptors for the detection and measurement of large chiral molecules which currently do not exist. Recently, Dr. Chambers has successfully constructed, tested and demonstrated highly selective discrimination of molecularly similar compounds including m-conotoxins, fluorescein, and NATA using the MI technology. In Phase I, SPEC and Dr. Chambers propose to develop and demonstrate the MI technology for biosensor detection and measurement of a candidate large chiral organic molecule of interest to NASA. Polymer based MI receptors are easily cleaned and sterilized with little or no binding degradation. In Phase II, SPEC will proceed to develop, construct and fabricate a compact MI biosensor prototype for chiral detection and measurement. The final biosensor system will be small, light-weight and require low power and will be suitable for planetary applications.
Potential Commercial Applications (Limit 200 words)
The development of compact, stable biosensors based on MI receptors has significant commercial applications as home diagnostic devices, medical research tools, food processing monitors, clinical instruments and environmental detectors as well as for NASA and the Department of Defense. In addition to its use for discrimination of chiral molecules, the MI biosensor can be used to detect toxins, dangerous chemicals, and hazardous environmental agents. MI devices could significantly impact on the projected half-billion dollar market for biosensors in the year 2000.

NEXT-GENERATION,
ROOM-TEMPERATURE XRF SYSTEM
Technical Abstract (Limit 200 words)
Current X-Ray Fluorescence (XRF) systems for
space in situ analysis and experimentation are
inadequate due to one or more of their basic
characteristics. Thus there are no room
temperature XRF systems, presently, which
simultaneously offer: large detector active area and
high energy resolution. The goal of this proposal is
to develop a novel, high performance XRF system
based on large active-area Silicon Drift Detectors
(SDD) that can operate over wide temperature and
pressure ranges to provide precise and accurate
elemental analysis of rock and soil samples as is
necessary for the Solar System Exploration
program. During Phase I we will develop a
demonstration unit consisting of a miniaturized, low
weight and, low power x-ray spectrometer based on
the large active area (50-100 mm2) SDD structure.
The electronic noise level of this system will be less
than 250 eV (FWHM). This level of energy
resolution with such a large active area will already
constitute a better than ten-fold improvement over
any existing x-ray spectroscopy system operating
near room temperature. In Phase II we will further
reduce the noise level of the system down to 70 eV
(FWHM) by use of SDD structures with integrated
first stage FETs. The unit developed during Phase I
will serve as a basic building block for the
construction of the XRF system in Phase II of the
project. The finalized XRF instrument will contain
the spectrometer, an excitation source, processing
electronics, and supporting software for data
collection and XRF analysis. The overall goal for
total mass, power and volume of the XRF
instrument is less than 1 kg, 1 W, and 1 liter,
respectively. High data rate will be assured by the
large active area (large solid angle) of the x-ray
detector, optimized geometry for sample excitation,
efficient software, and unparalleled high
performance of the system.
Potential Commercial Applications (Limit 200 words)
New small x-ray detector systems with unparalleled
high spectrometric performance obtained by new
large active area detectors which can operate near
room temperature with low power consumption will
be the basis of a new generation of novel portable
XRF spectrometry instruments. These new
instruments open up numerous important market
opportunities in the area of environmental
contamination monitoring and industrial process
control and material identification

Non-Destructive In Situ Detection of
Nucleic and Amino Acids
Technical Abstract (Limit 200 words)
We propose development of a laser capable of
emission at appropriate deep UV and visible
wavelengths to enable a nucleic and amino acid
detection system with low mass, low power
consumption, low cost, and non-destructive
characteristics, making this instrument highly
attractive for in situ exploration of Mars and
Europa.
All known examples of self-replicating terrestrial
organisms contain nucleic and amino acids.
Deep UV excitation (222-251 nm) of nucleic acids,
aromatic amino acids, or proline can produce a
Raman resonance event. Resonance response
increases signal strength by 102 to 104. Excitation
at these deep UV wavelengths avoids almost all
fluorescence activity usually encountered in
biological material, permitting (under controlled
laboratory conditions) the detection of a single
microbacteria.
The enabling break-throughs for in situ use of this
technology are recent advances in hollow cathode
metal ion lasers and miniature, monolithic
spectrometers as detectors. It is now feasible to
fabricate deep UV lasers 10-15 cm in length, 2-4 cm
in diameter, weighing 50-100 grams with an
electronics package of comparable size, and
drawing only 2-3 watts of electrical power. These
lasers are the enabling technology for the
micro-miniature extant life detectors and the focus
of the proposed development.
Potential Commercial Applications (Limit 200 words)
Deep UV sources of light are of great interest for a
wide range of biotechnology instrumentation
applications because of the ability to induce
fluorescence or Raman response in fluorophors
which occur naturally in most biological materials.
Presently the only sources of deep UV light for
these instruments are deuterium lamps or xenon
flashlamps. Both of these sources of deep UV are
very limited in source radiance and therefore are
very limited in their ability to induce response in
small sample volumes.
Because of the ongoing need to increase the speed
and specificity of analytical instruments, lasers are
increasingly used as light sources. Because of the
lack of availability of inexpensive, reliable, deep
UV lasers, present instruments commonly employ
visible lasers in conjunction with dye tags to identify
the biochemicals of interest. These dye molecules
are often as large as the molecules being
investigated and significantly alter the chemistry
and therefore the reliability of the results.
The deep UV hollow cathode metal ion lasers being
proposed eliminate the need for dye tagging and
are capable of providing over 10,000 times the
source radiance of a deuterium lamp at comparable
prices. This will significantly influence the future
design of instruments such as capillary
electrophoresis instruments, high performance
liquid chromatographs, DNA sequencers, and flow
cytometers.

Project Title:
Mars Micro Balloon Probe
Technical Abstract (Limit 200 words)
The Mars Micro Balloon Probe (MMBP) is a
project to create a low-cost airborne Mars
photographic probe with a trans-Mars injection
(TMI) mass an order of magnitude less than that of
any Mars balloon probe designed to date. This can
be done by approaching the gondola design in a
spirit of ruthless minimalism, reducing it to a single
instrument coupled with a computer, UHF radio
transmitter/receiver, and a primary battery power
supply suitable for a 1 day flight. In addition, large
mass savings and greater simplicity and reliability
can be achieved by replacing the traditional
complex high pressure hydrogen or helium inflation
gear coupled with superpressure or overpressure
balloons with a novel self inflating zero-pressure
polyethylene balloon using ammonia gas. By
combining these innovations, it should be possible
to create MMBP units with a total TMI mass,
including entry system, on the order of 10 kg. Such
light weight systems would be prime candidates to
fly as hitch-hiker payloads on any of the numerous
Mars orbiters or landers planned for the near
future. This would allow high resolution aerial
photography to be performed on Mars without the
loss of any of the surface or orbital science
currently planned.
Potential Commercial Applications (Limit 200 words)
POTENTIAL COMMERCIAL APPLICATIONS
The primary initial application of the MMBP
system is to provide a means aerial photographic
exploration on Mars. However the same system
could be used on Earth to carry out cheap remote
sensing missions for both scientific and commercial
purposes. For example small balloon gondola
systems of the MMBP type could be released by
fishing boats, and used to spot nearby areas where
plankton signatures indicate that fish are likely to
be plentiful. Meteorologists seeking look-down
data on cloud activity from altitudes of 32 km would
also find the MMBP systems extremely useful.
Oceanographers could use MMBP systems the
map the movement of polar ice. In fact, nearly
every form of commercial and scientific remote
sensing application in use on Earth today would
benefit from the development of low-cost, light
weight MMBP based photo-reconnaissance probe
that could be released by investigators on an
on-demand basis.

MCSM: A control strategy for
holonomic/nonholonomic robot systems
Technical Abstract (Limit 200 words)
The proposed innovation is mobile-camera-space
manipulation (MCSM), a strategy to control robot
systems with a combination of holonomic and
nonholonomic degrees of freedom (DOFs), such as
a rover equipped with a low-DOF arm. MCSM will
control both the rover and the arm to move the end
effector to a target in 3D space. MSCM will be an
extension of camera-space manipulation (CSM), a
proven estimation-based control strategy which
controls tasks in physical space by achieving task
objectives in camera-space. CSM's advantages
include being calibration-free, robust, and highly
accurate, but CSM requires cameras at fixed
positions, limiting its use for mobile systems with
large working areas. MCSM will control the rover
and the onboard low-DOF robotic arm, using
cameras fixed to the rover, to accomplish higher
DOF tasks than either could achieve individually.
MCSM could function in autonomous or supervised
control modes without performance degradation due
to delay times. The innovation responds to
Subsection 18.02, giving rovers more flexibility,
robustness, and accuracy for Sampling,
Deployment, and Retrieval tasks by allowing
rovers with low-DOF arms to achieve high-DOF
tasks such as sample grasping, coring, deployment,
storage, and retrieval of stored samples.
Potential Commercial Applications (Limit 200 words)
The proposed innovation will allow mobile
(nonholonomic) systems equipped with holonomic
degrees of freedom (such as rovers equipped with
arms, forklifts, earthmoving equipment, etc.) to be
controlled accurately, semi-autonomously, and
robustly. In addition, by combining both the degrees
of freedom of both subsystems, higher DOF tasks
can be accomplished without the need to add
additional holonomic degrees of freedom, which
would add cost, complexity, and weight. This system
would be ideal in two major several settings:
1) Control of rovers equipped with arms in order to
acquire or manipulate samples during exploration of
hostile environments, including Mars, deserts,
arctic environments, hazardous material storage
facilities, nuclear power plants, and potentially
underwater.
2) Semi-autonomous control of industrial equipment
such as forklifts for automated warehousing,
earthmoving equipment, farm equipment, etc. In
this case the innovation could be used both in new
equipment and as a retrofit for older equipment.
The increased accuracy and reduced labor costs are
two major advantages of this approach. If addition,
such equipment could be controlled remotely for
work in hazardous areas, and one operator could
control several pieces of equipment, increasing
productivity.

Electrochromic Thermal Control
Container for Payloads
Technical Abstract (Limit 200 words)
The development of tunable solar absorptance and
infrared emittance coatings for active temperature
control of thermally sensitive payloads is proposed.
The coatings will be applied to the exterior of
payload containers on satellites and planetray
explorers. Selected coatings facing the sun will
have a tunable solar absorptance and to control
heat gain while coatings facing the ground or night
sky will have a tunable emittance to control radiant
heat loss. The solar absorptance coatings will
switch from transmitting-to-absorbing or
reflecting-to-absorbing depending on whether solar
illumination inside the payload container is
desirable. Absorptance and emittance modulation
are obtained with electrochromic films of
amorphous and crystalline oxides that undergo
reversible optical changes in response to an
electrically driven (typically <5 V) change in
reduction-oxidation state. The Phase I objective is
the development of a demonstration container
incorporating variable solar absorptance and
thermal emittance panels and an evaluation of the
thermal control properties of the container with
emphasis on use in Mars exploration activities. The
objective of the Phase II program would be the
incorporation of the thermal control technology into
a payload container suitable for flight evaluation.
Potential Commercial Applications (Limit 200 words)
Thermal control enclosures will find application on
commercial and military satellites, and on planetary
explorers. Terrestrial applications in energy
efficient buildings and greenhouses are also
anticipated.

Project Title: Advanced Capillary Pumped Loop
Technical Abstract (Limit 200 words)
The capillary pumped loop (CPL) and the loop heat pipe (LHP) are passive heat transport devices that have several orders of magnitude greater capabilities than heat pipes, and are expected to become the thermal control systems for the next generation of spacecraft. The CPL can have multiple evaporators in a single system and its set point temperature is easily controllable. However, CPLs require lengthy startup/re-start processes, and other operational and design constraints due to its sensitivity to vapor bubble presence inside the evaporator liquid core. In addition, CPLs have been limited to low performance plastic wicks to mitigate this problem. The LHP is mostly insensitive to vapor inside the liquid core and use high performance metal wicks, but lack temperature controllability and may be difficult to plumb multiple evaporators due to fluid inventory sensitivity. Other LHP limitations include shorter lengths evaporators than CPLs. The Advanced Capillary Pumped Loop (A-CPL), whose development is proposed here, combines the unique features of CPLs and LHPs to provide a loop that is insensitive to vapor presence in the evaporator liquid core, can have multiple/long evaporators, is temperature controllable, and can utilize high performance / high conductance metal wicks.
Potential Commercial Applications (Limit 200 words)
If successfully developed, the A-CPL would be one of the enabling technologies for the next generation of higher power / smaller government and commercial spacecraft. It will provide more than an order of magnitude greater heat transport and ground testability than state-of-the-art heat pipes, like CPLs and LHPs. However, the A-CPL will not have any of the undesirable functional and design shortcomings that currently limit CPL and LHP applications. In addition, the A-CPL will allow the realization of significant weight, size, and cost reductions that are not possible with any existing two-phase heat transport devices. The A-CPL would not be limited to only space based applications. Interest is currently growing in the aircraft, ship, and earth based electronics system industry for high performance, passive heat transport devices.

Thermal Control Using Multi-Spectral
Switching
Technical Abstract (Limit 200 words)
This Phase I SBIR proposal presents a new and
novel approach to active thermal control. It uses an
electrically controlled film that can give
independent control on both the visible absorption
and the LWIR emissivity. This dual control gives a
degree of thermal control previously unattainable.
During the Phase I program, an electrically
switchable thermal control coating will be
fabricated. This coating is based on an
electrophoretic system with a special pigment to
minimize absorption in the binder so the IR
emissivity can be controlled.. This control coating
will be lightweight, rugged, low cost and require
minimal power. It will be switchable from a value of
1.5 (ratio of solar absorbence to thermal emittance)
to 0.24.
Sensortex has demonstrated the basic approach
with both single pigment and double pigment
switching, including the charging and attraction of
metallic flake pigments to the surface with the
desired orientation, initially thought to be a major
problem. Fabricating a practical coating requires
detailed system design but does not require any
technical breakthroughs.
Potential Commercial Applications (Limit 200 words)
A new and novel active control system will have
multiple uses in temperature control. It is
lightweight which will be a major advantage in space
applications while the active control of both
absorption and emissivity will be useful in solar
heating and cooling.

A Constant Capacity High Lift Heat
Pump
Technical Abstract (Limit 200 words)
Future manned lunar bases will have thermal
control requirements that exceed the capabilities of
conventional heat pump technology. While prior
NASA studies have demonstrated the feasibility of
solar powered heat pumps for habitat thermal
control, a suitable heat pump design capable of
maintaining a constant cooling capacity over the
widely varying lift conditions encountered in a
typical equatorial lunar base has not been
identified. Magnetic bearing technology and
judicious refrigerant selection have allowed
Mainstream Engineering Corporation to develop a
highly efficient, compact, high speed, direct drive
centrifugal refrigeration compressor for terrestrial
chiller systems. This innovative patented
technology can be easily adapted to a high lift, lunar
heat pump thermal control system with minor
modifications. Mainstream Engineering
Corporation has demonstrated the potential of the
high-efficiency, lightweight, magnetic-bearing
centrifugal chiller to provide improved
performance, significantly reduced operational and
maintenance costs, and reduced life cycle cost.
Potential Commercial Applications (Limit 200 words)
Development of a high lift heat pump has
commercial applications in the development of
air-cooled condenser chillers. In addition, the
technology and control system enhancements
necessary to adapt magnetic bearing compressors
for lunar heat pump applications would greatly
improve the high efficiency operating envelopes of
current designs. Marketing studies have indicated
that Mainstream Engineering Corporation's current
design has an excellent opportunity to capture a
significant portion of the projected 80,000
commercial chillers that will be replaced in the next
five to ten years. Therefore, while Mainstream
Engineering Coporation's existing design is
comparable in initial cost, it provides significant
reductions in total life cycle cost, while also being a
completely environmentally-safe alternative to
existing CFC and HCFC systems. Development of
this technology will have enormous economic
benefits. The Air Conditioning and Refrigeration
Institute estimates that over 80,000 CFC chillers
are still in operation and must be replaced or
retrofitted in the coming years.

Flexible, Lightweight Radiator for an
Inflatable Mars Spacecraft
Technical Abstract (Limit 200 words)
NASA has established an initiative for the manned
exploration of Mars using an inflatable
spacecraft/habitat. The inflatable nature of this
spacecraft implies that the heat rejection radiator
must be flexible and foldable. Overall feasibililty of
flexible radiators has been demonstrated, however,
limited work has been done to design and qualify
the flexible radiator materials for extended space
missions.
Accordingly, the objective of this Phase I is to
establish a baseline for the performance of the
flexible radiator materials with respect to atomic
oxygen, ultraviolet radiation, flex fatigue failure,
thermal cycling, micro meteoroid puncture and
optical properties. Several candidate flexible
radiator materials will be tested. The Phase I work
will conclude with recommendations for material
improvements. In Phase II, these improvement wil
be implemented and the materials re-tested.
Ultimately, the best material will be selected and a
prototype radiator will be constructed and thermal
vacuum tested.
Potential Commercial Applications (Limit 200 words)
The largest commercial application for flexible
radiators is satellite thermal control. Presently,
various organizations are planning to place
constellations of satellites into orbit. With the
demand towards smaller size and higher power, a
flexible radiator that can be compactly rolled or
folded, stored for launch and deployed in orbit to
present a large radiating area would be not only
beneficial but enabling for these satellites. In
addition, a lightweight radiator will have significant
economic benefits due to the reduced launch
payload weight and volume.

High Thermal Conductivity, Tailored
CTE FCOB Packaging Concept.
Technical Abstract (Limit 200 words)
The proposed innovation is an ultra-lightweight,
flip-chip-on-board (FCOB) packaging approach with
thermal performance and CTE matching to achieve
high reliability, low cost electronics. This new
product will feature a CTE, tailorable by design, to
achieve any value from 3-10 ppm/oC, an in-plane
thermal conductivity 20%-30% higher than
state-of-art metal-cored PWB substrates, and will
also weigh up to 50% less than conventional PWBs
with IC packages soldered to the surface. This new
system will achieve this performance by utilizing a
special AMT designed graphitized carbon
composite material for dimensional constraint and a
CTE-matched encapsulant resin system. The
encapsulant resin will be based on low CTE
epoxies/resins and combined with low CTE filler
particles to further drive down the overall
encapsulant CTE. This PWB system will allow
FCOB technology to be integrated into existing
circuit board practices by utilizing core and
encapsulant technologies to minimize stresses at
solder joints and leads due to PWB/chip CTE
mismatch. This new product will adapt current
practices for PWB fabrication to more efficiently
enable the use of FCOB for critical high power
dissipation/high electronic component density
applications.
Potential Commercial Applications (Limit 200 words)
Increasing numbers of critical electronic systems
applications employ chip-on-board technology.
Examples of such usage are found in portable
computers and cellular and PCS (Personal
Communications Systems) telephones. The
availability of the proposed high performance/high
reliability substrate will enable smaller and more
powerful devices. This new laminated substrate
should also enable commercial and military
applications for FCOB in thermal environments that
were previously too severe for current technology,
i.e. satellite and avionics communications and
navigation electronics. This packaging approach
offers tailorable FCOB technology-enabling CTE,
higher thermal conductivity for higher component
reliability, and virtually half the weight of any
conventional solution unmatched by any PWB with
soldered-on IC packages to date.

Phase I will demonstrate an advanced variation of the Technology Management, Inc. (TMI) solid oxide fuel cell (SOFC) in a passive regenerative fuel cell (RFC) system suitable for space applications. The demonstration integrates both fuel cell and electrolyzer functions into a single device, eliminates all moving parts and heat exchangers, reduces stack mass and volume, reduces size and complexity of auxiliary systems, and operates like a rechargeable "hydrogen-oxygen battery." TMI has previously demonstrated the TMI SOFC/electrolyzer operating at greater than 90% energy storage efficiency. To operate as a passive reversible fuel cell/electrolyzer, the TMI stack must be able to operate with diffusion-driven reactant flows in place of the forced convection normally used in fuel-cell-only systems. The proposed Phase I will demonstrate the feasibility of diffusion-based cell operation using modified TMI?s cell components.

Project Title: Low Temperature Ultracapacitor for Planetary Exploration
Technical Abstract (Limit 200 words)
Ultracapacitors for low temperature (-100°C) operation will be developed for use as power supplies in space and planetary exploration. These rechargeable power supplies are crucial for the deployment of exploration vehicles such as rovers, landers, and penetraters as well as for low temperature burst power communication. The sub-ambient conductivity and liquid range of present ultracapacitor electrolytes severely limit low temperature use. By extending our technology on imidazolium based electrolytes, we will develop a nonaqueous electrolyte for the low emperature
operation of ultracapacitors. In Phase I we will demonstrate a nonaqueous electrolyte with good low temperature conductivity (>5 mS/cm at -100°C),electrochemical stability, and wide liquid range (m.p. <-100°C). We will also measure the phase transitions of these electrolytes and determine the ultracapacitor performance from room temperature down to -80°C. In Phase II of this development we will optimize our prismatic packaging technology for low temperature operation and optimize low temperature electrolyte formulations. The innovation will allow for a long cycle life (>10,000 cycles) rechargeable electrical energy storage device with excellent low temperature energy and power performance facilitating planetary probes.
Potential Commercial Applications (Limit 200 words)
Success of this project will result in packaged nonaqueous electrochemical capacitors having increased energy density (>8 Wh/kg, >8 Wh/l) and power density (>0.5 kW/kg, >0.5kW/l) with a useful operational range down to -100°C. Electrochemical capacitors based on the developed system have commercial application in electric vehicles, cellular communication, uninterruptible power supplies, memory backup, and consumer electronics. The specific low temperature developments of this project will facilitate the commercial use of these power supplies in sub-ambient and extreme conditions such as in space (e.g. satellites) and in the arctic.

Project Title: Flexible Thin-Film CIGS High-Voltage Array for Space
Applications
Technical Abstract (Limit 200 words)
Spacecraft power is critical to any mission and is dictated by spacecraft power requirements and power losses. Minimizing power losses reduces the size and weight of the power system. Reducing current and increasing array voltage results in reduction of both power loss and electromagnetic drag/torques on the vehicle. Also, weight of ion propulsion power conditioning equipment can be reduced by high-voltage arrays. However, interaction between solar arrays and surrounding plasma in orbit can cause arcing on the solar arrays. Generally arcing occurs at sharp edges and exposed contacts, which are inherent with conventional crystalline solar array construction (solar cells, protection diodes, solder, thick coverglass). Our large-area, flexible thin-film copper-indium-gallium-diselenide (CIGS) photovoltaic technology (Fig. 1) provides high voltage arrays with less than 10µm profile changes through monolithic integration. CIGS does not need conventional coverglass; only an emittance-enhancing coating on the entire array surface after integration should suffice for thermal management and a dielectric barrier. Global Solar Energy?s proposed effort, "Flexible Thin-Film CIGS High Voltage Arrays for Space Applications" in response to NASA SBIR Crosscutting Technologies 19.02 is to evaluate the required material for use in high-voltage arrays and to assess the design of said thin-film CIGS arrays for future spacecraft.
Potential Commercial Applications (Limit 200 words)
High-voltage photovoltaic solar arrays will have significant impact on both terrestrial and space applications within the consumer, commercial, and government marketplace. High voltages eliminate the need for heavy cabling which is a cost deterrent to cost-conscious PV applications, regardless of space or terrestrial applications. For space applications investigating ion propulsion, a high-voltage array is a natural in that the weight and cost of the power conditioning can be reduced, as well as reliability being improved. Such applications include communication infrastructure spacecraft Teledesic), orbit lifting vehicles, and deep-space missions. In terrestrial applications,utilities would prefer a high voltage array to reduce cabling cost, as well as to provide much easier DC-AC inversion and direct-to-grid applications. Many of the topics to be investigated within this program can be applied to safety-related issues for both space and terrestrial arrays, such as high-voltage isolation and fire safety. Furthermore, the flexible covercoat proposed to electrically isolate and thermally control array performance in space can replace costly Teflon™-based coatings for portable power applications.

Considerable work on AMTEC has been reported.
The key component of AMTEC is
Na-beta"-alumina solid electrolyte (BASE). In an
AMTEC, the typical geometry of BASE is tubular
and is fabricated by a conventional process. The
conventional process requires encapsulation to
minimize the loss of soda by evaporation and the
resulting BASE is also extremely
moisture-sensitive due to remnant NaAlO2 at grain
boundaries. MSRI has recently developed a novel
vapor phase process which can be used to directly
convert sintered alfa-alumina into
Na-beta"-alumina. The MSRI process has several
advantage over BASE. There are: (1) Lower
processing temperature obviates the need for
platinum encapsulation, thus lowering the overall
coast. (2) Grain boundaries are completely devoid
of NaAlO2, thus making the material
moisture-insensitive. (3) The BASE so-produced
exhibits crystallographic texture, thus increasing
conductivity. (4) Thin-wall ( 500 micrometer), free
standing tubes can be made. The present work is
proposed to evaluate the BASE fabricated by the
novel MSRI process for application in AMTEC.
The technical objectives of the proposed work
include: (1) Fabrication of BASE by the novel vapor
phase process. (2) Evaluation the mechanical and
electrical properties. (3) Enhancement of the
process kinetics through manipulation of the defect
chemistry of BASE (4) Measurement of
conductivity and durability in sodium vapor.
Potential Commercial Applications (Limit 200 words)
The anticipated commercial applications of BASE
made by the novel vapor phase process include: (1)
Solid electrolytes for AMETC, both sodium and
potassium for power generation in terrestrial
applications, space nuclear power, and industrial
co-generation. (2) Solid electrolytes for sodium
sulfur batteries with application in utility industry
and electric vehicular applications. (3) Solid
electrolytes for sensors and metal purification in
industry.

Project Title:
Application Specific, Optimum
Performance Design for
Nickel-Hydrogen Cells and Batteries
Technical Abstract (Limit 200 words)
Given the high level electrical performance
requirements for a specific space application, it is
desired to select a battery configuration that most
effectively meets the mission requirements in terms
of energy density, life cycle cost, cycle life,
spacecraft orbit, and power system redundancy. In
determining the most effective cell/battery
configuration, large numbers of variables must be
traded in order to arrive at the most effective
solution. These variables include such items as
power system architecture, battery chemistry, cell
dimensions, internal component selection, heat
rejection requirements, etc.
The objective of this project is create a rule based
system that captures expert rules, i.e. collective
industry experience, for selecting the ideal
Nickel-Hydrogen cell and battery configuration for
a given application. All configurations designed by
this system would be in keeping with current
industry practices. This system would serve as a
foundation for a system that would ultimately
include all pertinent battery chemistries and their
associated cell and battery configurations. In
addition to an intensive focus on electrical
performance, a fully implemented system would
also evaluate complete structural and thermal
concerns; concerns critical to accurate weight
assessment.
Potential Commercial Applications (Limit 200 words)
Resulting from this contract will be a fully
functional, rule based technology, ANSYS finite
element interface. This interface will interpret
geometry created by a rule-based model and create
the corresponding thermal and structural finite
element models. This interface will enable
extremely rapid thermal and structural finite
element analysis (FEA). Rapid and accurate FEA is
an issue relating to virtually all
design/manufacturing organizations. Aerospace,
automotive and many other industries rely on such
analysis. Order of magnitude acceleration of this
type of analytical work is of great interest to
ANSYS Inc., the supplier of the ANSYS finite
element code.

Project Title: Flexible Thin-Film CIGS High-Voltage Array for Space Applications
Technical Abstract (Limit 200 words)
Spacecraft power is critical to any mission and is dictated by spacecraft power requirements and power losses. Minimizing power losses reduces the size and weight of the power system. Reducing current and increasing array voltage results in reduction of both power loss and electromagnetic drag/torques on the vehicle. Also, weight of ion propulsion power conditioning equipment can be reduced by high-voltage arrays. However, interaction between solar arrays and surrounding plasma in orbit can cause arcing on the solar arrays. Generally arcing occurs at sharp edges and exposed contacts, which are inherent with conventional crystalline solar array construction (solar cells, protection diodes, solder, thick coverglass). Our large-area, flexible thin-film copper-indium-gallium-dieseling (CIGS) photovoltaic technology (Fig. 1) provides high voltage arrays with less than 10µm profile changes through monolithic ntegration. CIGS does not need conventional coverglass; only an emittance-nhancing coating on the entire array surface after integration should suffice for thermal management and a dielectric barrier. Global Solar Energy?s proposed effort, "Flexible Thin-Film CIGS High Voltage Arrays for Space Applications" in esponse to NASA SBIR Crosscutting Technologies 19.02 is to evaluate the equired material for use in high-voltage arrays and to assess the design of said thin-film CIGS arrays for future spacecraft.
Potential Commercial Applications (Limit 200 words)
High-voltage photovoltaic solar arrays will have significant impact on both terrestrial and space applications within the consumer, commercial, and government marketplace. High voltages eliminate the need for heavy cabling which is a cost deterrent to cost-conscious PV applications, regardless of space or terrestrial applications. For space applications investigating ion propulsion, a high-voltage array is a natural in that the weight and cost of the power conditioning can be reduced, as well as reliability being improved. Such applications include communication infrastructure spacecraft (Teledesic), orbit lifting vehicles, and deep-space missions. In terrestrial applications, utilities would prefer a high voltage array to reduce cabling cost, as well as to provide much easier DC-AC inversion and direct-to-grid applications. Many of the topics to be investigated within this program can be applied to safety-related issues for both space and terrestrial arrays, such as high-voltage isolation and fire safety. Furthermore, the flexible covercoat proposed to electrically isolate and thermally control array performance in space can replace costly Teflon™-based coatings for portable power applications.

Project Title: Low-Cost, Partially Fluorinated Nanostructured Polymer for PEM Fuel Cells
Technical Abstract (Limit 200 words)
The specific power of PEM fuel cells could surpass that of internal combustion engines if lighter, more conductive membranes can be found. Perfluorinated polymers (Nafion) have exceptional stability, because of their high fluorine content. However, the high associated cost and weight and need for complex humidification systems make perfluorinated PEMs noncompetitive for portable and automotive applications. A new class of proton-conducting polymers is proposed, which possess nanosized hydrophillic/hydrophobic domains like those found in Nafion but contain less fluorine. Unlike linear-chain polymers, the polymer-backbone structure is spherical and coated with functional groups to allow spontaneous formation of ion-conducting, interstitial cavities/surfaces outside the polymer core. This microstructure separates proton motion from polymer-chain motion, to allow unhindered ion mobility even when most of the polymer is dry. The functional groups forming the ion channel walls provide versatile reaction pathways for controlling the chemical environment surrounding the proton.
These groups will be derivatized with various quantities of triflate-based acids, fluorinated protecting groups, and hydrating/solvating groups to achieve improved PEM properties. TPL will leverage its production experience in nanocomposites and thin-film dielectrics to process polymers into cost-effective PEMs, that will be tested in prototype H2/O2 cells at Sandia National Laboratories to determine structure/performance relationships.
Potential Commercial Applications (Limit 200 words) The cost of the proton-exchange membrane is the largest cost driver for PEM fuel cells. The benefit of a successful program will be the development of economical, lightweight fuel cells to power portable electronics, such as laptop computers, video equipment, lights, and electrically powered tools; a several hundred million dollar market. And the PEM fuel cell is the power plant of choice for zero-emission vehicles if the membrane cost can be reduced by a factor of six.

Project Title:
Inflation Rigidized Solar Concentrators
for Power Generation
Technical Abstract (Limit 200 words)
Current solar thermal power systems incorporate
rigid concentrators which are either assembled in
orbit or mechanically deployed. These structures
are relatively heavy, complex, require significant
package volume, and are costly. The development
of lightweight deployable concentrators for solar
thermal power applications would reduce weight,
and cost for these systems, making them
considerably more cost effective for large space
power applications. The proposed Phase I research
will apply innovative polymer film fabrication
techniques to design an inflatable concentrator for
subsequent ground testing. The concentrator will be
fabricated in a parabolic shape without seams or
gore sections. The one piece nature of the cast film
will reduce the inflation pressure requirements and
increase its tolerance to micrometeroid penetration.
The inflation rigidized thin film concentrator will be
designed to interface with solar dynamic power
systems. Deployment of a test article from a
storage canister will be demonstrated, and the
concentrator will be optically characterized. This
proposed innovation will result in an order of
magnitude reduction in cost for solar thermal power
systems.
Potential Commercial Applications (Limit 200 words)
Lightweight large deployable collectors have
potential applications to commercial space-based
antennas, solar power generation, solar bimodal,
and Earth survey applications. The materials and
processes used in the fabrication of collectors have
application for thermal control blankets and low
dielectric materials for flexible circuit boards.

Project Title:
Shaftless, Magnetically Levitated
Flywheel Energy Storage Systems
Technical Abstract (Limit 200 words)
MagneMotion, Inc. proposes to design and build a
novel shaftless flywheel energy storage system
capable of achieving high energy density, long life,
and low cost. The concept utilizes a combination of
maglev and linear motor technology with a
simplified control system, efficient power
conversion and a shaftless rotor. If the basic design
is proven in Phase I, then the rotor will be expanded
to include a wound carbon fiber extremity that has
the potential to deliver energy and power densities
higher than the best electrochemical systems, but
with longer life and less sensitivity to temperature
extremes.
A single, stationary permanent magnet structure
provides both suspension and guidance forces with
a control system that adapts the suspension to
operate at the most efficient position and also
provides damping of unwanted modes. The
propulsion system is based on a linear synchronous
motor with permanent magnets on the inside of the
rotor, and no ferromagnetic material on the stator
so the standby losses are very low. The motor
provides both power transfer to and from the wheel.
The combination of magnetic suspension and linear
motor propulsion is adapted directly from
MagneMotion's operational hardware for
automated transportation.
Potential Commercial Applications (Limit 200 words)
There are many terrestrial applications ideally
suited to flywheel energy storage application if a
system can be built at reasonable cost and if it
provides rapid and efficient energy transfer for
hundreds of thousands of charge and discharge
cycles. We believe that the design proposed here is
fundamentally less complex and less expensive
than any existing flywheel energy storage system,
and hence has substantial commercial potential. For
example, automated transportation is the core of
MagneMotion's business and we foresee a number
of applications in this arena, including power peak
shaving for rapid transit systems and standby
power for personal rapid transit.

Project Title: Long Cycle Life, High Energy Density Li-Ion Battery
Technical Abstract (Limit 200 words)
The battery is based on a novel lithium intercalation anode which we expect to a) double the capacity of graphite anodes, b) eliminate the irreversible capacity from electrolyte reduction, c) enhance safety over conventional anodes and d) greatly extend cycle life. Coupled with our advanced polymer electrolyte and high voltage cathode, we expect a fully developed battery to have a pecific energy of >150 Wh/kg, an energy density of >300 Wh/l and the capability to provide >1000 deep charge/discharge cycles. This Li-ion battery would also be safer than its carbon anode counterpart, especially in the larger sizes of 20-50 Ah needed for many space applications.The proposed Phase I effort is designed to demonstrate the feasibility of our approach by synthesizing and physically and electrochemically characterizing the new Li intercalation anode host material. More extensive anode and cell development will follow in Phase II.
Potential Commercial Applications (Limit 200 words)
The new Li-ion battery will find wide application wherever high energy density, safety and long cycle life are important. This includes portable computers, communication equipment, camcorders, power tools and autonomous robots in remote locations.

High Density DC-DC Converter
Modules for Satellite Applications
using Multilayer Hybrid Packaging
Technical Abstract (Limit 200 words)
VPT proposes to design a series of innovative
high-efficiency, radiation-resistant, space-qualified,
standardized DC-DC converter modules using
several new VPT-proprietary technologies. These
technologies include a new high density multilayer
chip and wire hybrid packaging technology, a new
integrated magnetic power circuit topology, and a
new magnetic feedback control technique. These
modules will be compatible with the requirements of
several popular new high-voltage regulated satellite
busses: Space Station,+120Vdc; Space Systems
Loral, +100Vdc; Hughes, +100Vdc; and
Lockheed-Martin, +70Vdc. While such DC-DC
converter modules have become the industry
standard in the telecommunication, aircraft, and
military markets, the satellite industry has been
slow to accept their use. This is because the
modules often have low efficiency and often use
radiation sensitive parts (such as opto-couplers in
the feedback path). In addition, there is a relatively
limited selection of converters that can
accommodate the new standard high-voltage
satellite busses. The lack of available standard
space-qualified products has forced the vast
majority of satellite power converters to be costly,
long-lead-time, custom designs. VPT's modules will
offer higher efficiency by taking advantage of the
reasonably well-regulated satellite bus voltages.
They will also offer parallel capability to achieve
higher output power and separate EMI filter
modules to meet differing noise immunity
requirements.
Potential Commercial Applications (Limit 200 words)
This technology is applicable to all commercial
satellite manufacturers including Hughes, TRW,
Loral, and Lockheed. There is a vital need for high

space applications.

Project Title: Low Cost, Light Weight CMC Rocket Components
Technical Abstract (Limit 200 words)
Launch and satellite engine technologies are being driven concurrently to higher performance and reduced inert mass in order to make possible satellites, reusable and expendable launch vehicles, deep space vehicles, and single-stage to orbit vehicles with improved useable payload fractions. While NASA has been developing ceramic matrix composite (CMC) technologies for over a decade, for the first time propulsion companies are embarking on a serious effort to incorporate CMC components in engine designs in order to utilize CMC's light weight and performance enhancement potential. Unlike in the past, when it was thought only dramatic increases in performance would justify the costs associated with development, design, and qualification of new engine materials, use of lighter weight CMC materials which withstand even modest increases in combustion temperatures, e.g. 2700oF vs 2400oF, are now predicted to yield weight savings justifying such an outlay. In this SBIR program, Refractory Composites, Inc. (RCI) will fabricate and test CMC liquid rocket chambers in order to demonstrate that CMC fabricationtechnologies and design methodologies currently have the maturity level necessary to produce economically viable CMC components which satisfy newly developing industry requirements.
Potential Commercial Applications (Limit 200 words)
RCI envisions a number of commercial advanced rocket propulsion applications including combustors on expendable launch vehicles, reusable nozzle extensions, light weigh components for Deep Space Missions, and components for divert thruster and ACS.

High Efficiency Neutralizer for Electric
Propulsion
Technical Abstract (Limit 200 words)
The Physitron Team proposes to apply Chemical
Vapor Deposited (CVD) Diamond micro-tip field
emitter arrays (FEAs) to electric propulsion. These
arrays consist of micro-fabricated pyramids of CVD
diamond which have been demonstrated to have
extremely low thresholds for electron emission.
Current small electric propulsion systems waste as
much as 30% of the available energy in generating
electrons for ionization and neutralization.
Application of this technology will reduce the size,
weight, and power requirements of these
subsystems by utilizing micro electro-mechanical
systems (MEMS) technology and significantly
increasing the efficiency of electron production. The
long term objectives of this project are to deploy
Diamond MEMS FEAs in neutralizers for electric
propulsion and as plasma contactors for spacecraft.
During Phase 1, we will demonstrate adequate field
emission properties of the FEAs, design a CVD
diamond grid structure, and deliver FEAs to NASA
for inspection. During Phase 2, we will fabricate and
deliver a pre-prototype neutralizer with diamond
MEMS FEAs and a diamond grid which will provide
60 milli-amps at 2 volts bias with 95% efficiency
from a 1 square millimeter device.
Potential Commercial Applications (Limit 200 words)
Micro-fabricated CVD diamond FEAs have been
demonstrated to have the absolute lowest threshold
for electron emission and the lowest erosion rate
for ion bombardment. Therefore, numerous
commercial applications exist including spacecraft
propulsion systems, high power/frequency vacuum
tubes, and flat panel displays. The low voltage
emission and high temperature capability of
diamond is an excellent match to high power
microwave devices. The low threshold for and
uniformity of emission provided by the FEA
approach will allow lower power flat panel displays
for portable applications such as laptop computers.

Catalysts and Catalytic Thermal Bed
Materials for HAN-based
Monopropellants
Technical Abstract (Limit 200 words)
There are currently several hundred active
satellites in orbit, at least half of which use
hydrazine monopropellant. In addition, every year
approximately 20 upper stages use hydrazine
monopropellant for roll control and propellant
settling maneuvers prior to orbit insertion burns.
There has been increasing concern about toxicity of
hydrazine(s). Safety regulations have been
tightened to the point where fueling has become a
significant part of the overall cost of a spacecraft
launch. Nontoxic monopropellants as replacement
for hydrazine promise faster and more economical
fueling operations, resulting in lower life-cycle cost.
Nontoxic monopropellants would also enhance the
safety of future manned spacecraft such as the
Crew Return Vehicle. This SBIR proposal is in
response to NASA SBIR solicitation 97-1 which
under subtopic 19.04 calls for "High performance
monopropellants for small spacecraft applications.
Included in this area are ignition techniques for
these propellants that will meet the severe duty
cycle requirements of on-orbit propulsion
functions." The catalysts proposed here are the
most reproducible ignition technique and promise to
achieve the same reliability as that already
demonstrated with hydrazine thrusters. The product
of this SBIR has near-term applicability to NASA
and ties in directly with nontoxic propellant thruster
development in progress at NASA contractors.
Potential Commercial Applications (Limit 200 words)
More than half of all U. S. satellites launched
between 1987 and 1997 were for commercial
applications. All U. S. launch vehicle upper stages
such as Delta II, ATLAS-II, LMLV or PEGASUS
are built by commercial launch service providers. In
most cases hydrazine monopropellant can be
replaced by a nontoxic monopropellant with
resulting cost-saving benefits that would be passed
on to customers like NASA and other branches of
the U. S. Government. In a few cases, it may be
possible to substitute existing systems with a
drop-in replacement using a nontoxic propellant.
The potential market for the catalyst to be
developed under this SBIR and its Phase II and
Phase III follow-on contracts is the same as that for
Shell 405. The material may eventually replace
Shell 405 in all monopropellant thruster and gas
generator applications.

Project Title: Laser Ignition of Liquid Oxygen/Ethanol Propellants
Technical Abstract (Limit 200 words)
NASA is continuously seeking non-conventional innovative technologies to obtain safer, more reliable and more economical systems in order to improve US competitiveness in the space industry. One potential area for significant cost reduction is replacing current toxic propellants with environmentally friendly propellants. However, these new propellants are not hypergolic. This presents a new challenge, demanding a reliable ignition system.
This proposal offers a novel ignition concept based on laser-induced plasmas (LIP). Attainment of laser ignition will require simultaneous control of several key parameters governing the interaction between laser optics and the propellants. The most innovative aspect of this concept is the employment of dual pulse laser with an adjustable gating to overcome the anticipated strong
attenuation of the laser energy by the optically dense liquid propellants.
The primary objective of Phase I is to experimentally determine the feasibility of the proposed LIP ignition with liquid oxygen/ethanol, which is considered to be one of the most promising non-toxic propellants combination. Consistent with this overall objective a detailed work plan is proposed, advancing the concept from laboratory experiments to subscale demonstration through progressive and well-thought stages.
Successful completion of Phase I will affirm feasibility as well as provide the technical data base for a comprehensive Phase II program, during which a prototype laser ignition will be designed, constructed and tested.
Potential Commercial Applications (Limit 200 words)
Laser ignition of non-toxic propellants will benefit the space industry by enabling the use of common propulsion systems and components across multiple vehicles and missions having generic requirements for space maneuvering and altitude control. This, in turn, will drive the cost down, improving U.S. competitiveness in the space industry.

Rapid, Cost-Effective Fabrication of
Fiber-Reinforced Composites for High
Temperature Operating Environments
Technical Abstract (Limit 200 words)
Current reusable thermal protection/structural
systems have a maximum operating temperature of
approximately 1700°C. Increasing operation to the
2000-2500°C range would provide an increase in
heat flux capability from two to five times that of
the coated carbon/carbon (C/C) used on the space
shuttle orbiter. Fiber-reinforced diboride matrix
composites are an attractive alternative to coated
C/C for various engine hot section components and
airframe leading edges due to their superior
performance in an oxidizing environment. In this
Phase I project, Ultramet proposes to demonstrate
the feasibility of a novel high-speed process for
fabricating high temperature fiber- reinforced
zirconium diboride (ZrB2) matrix composites which
will show tremendous cost savings over current
processing technology, which involves hot-pressing
of powder or prefabricated layers of matrix
material. Each of the steps in the proposed process
takes only a few hours (rather than weeks or
months), yielding tremendous time and cost
savings, and is readily applicable to large, curved
surfaces. This process has been demonstrated at
Ultramet with carbide matrices and braided carbon
fiber preforms but not with a boride matrix. In this
process development and demonstration effort,
Ultramet will investigate the effects of processing
conditions, fiber type, and fiber architecture on the
high temperature mechanical properties and
oxidation resistance of these fiber-reinforced
composites.
Potential Commercial Applications (Limit 200 words)
The optimization of a high-speed process for
fabricating composites for high temperature
(2000-2500°C) applications will permit significant
advances in a wide variety of applications, including
uncooled leading edges for hypersonic vehicles,
nozzles for both solid- and liquid-fueled rockets
(including commercial satellite launch applications),
high temperature furnace heating elements, heat
shields, and hot section components for both turbine
and ramjet engines.

BEAM CURING OF ADHESIVES
AND COMPOSITES
Technical Abstract (Limit 200 words)
Curing of fiber-reinforced polymer composites and
adhesives using high-energy electron beams (EB)
offers impressive advantages for the manufacture
and repair of launch vehicle and spacecraft
components. EB curing uses low-cost tooling in a
room temperature process to significantly lower
composite fabrication costs. Novel designs using
EB co-curing and co-bonding have been developed
to reduce part count while maintaining good

Laboratory (SRL) has developed advanced curing

fabrication of spacecraft and launch vehicle
components. These include high power and portable
electron guns and novel B-stageable composite
resins for high throughput applications. High power
EB curing equipment includes a new generation of
pulsed linear induction accelerators with
all-solid-state pulsed-power drivers that scale to
megawatt power levels at a capital cost for the
accelerator of less than $3/Watt. SRL will
collaborate with the University of Delaware to
develop and test new electron-beam curable
adhesives for fabrication of spacecraft and launch
vehicle components. Phase I will investigate three

Project Title:
A Low Risk, Low Cost Manufacturing
Method for Lightweight RLV
Expanding Wall Structures
Technical Abstract (Limit 200 words)
Foster-Miller will demonstrate a low risk
manufacturing method for high performance,
low-cost, lightweight ceramic matrix composite
structures for the RLV Aerospike Engine
Expanding Wall that is technically and economically
feasible. Foster-Miller will do this by employing
resin transfer molding, ceramic precursors, and
ceramic fiber reinforcement to build curved panels,
representative of those found in the RLV
Expanding Wall, with internal cooling channels. To
achieve the overall objective, Foster-Miller will
work closely with our commercialization partner
Boeing-Rocketdyne Division, the manufacturer of
the RLV engine, and NASA to address materials
selection, component design, and overall
performance requirements.
The proposed innovation address the need to
improve the overall performance of the RLV
Aerospike Engine by reducing weight and thus
increasing thrust-to-weight. The innovative
technique also is a low risk, potentially low cost
manufacturing approach to large, complex,
high-temperature continuos fiber-reinforced
ceramic matrix composites, often very difficult or
impossible with CVI techniques. The proposed
manufacturing can be employed for a variety of
rocket and turbojet engine components including
ducts, stators, cooled/uncooled nozzle components,
and turbopump components.
Potential Commercial Applications (Limit 200 words)
At the end of the Phase I effort, NASA will have a
proven, low risk technique for fabricating fiber
reinforced ceramic matrix composites with internal
cooling passageways. The technique will be
applicable to a variety of ceramic materials systems
and rocket and turbojet combustion pathway
components. At the end of Phase II, a subscale
expanding wall article will be ready for testing in a
rocket environment.

Project Title: Low Mass Metal Matrix Composites for Lines/Duct Flanges and Cooled Nozzle Stiffeners
Technical Abstract (Limit 200 words)
This proposal proposes the use of metal matrix composites to reduce launch mass of fuel duct flanges and rocket nozzle stiffeners by 64% to 87%. To accomplish this, it is necessary to optimize aluminum matrix alloys for reinforcement by B4Cp particulates (for flanges) and high strength alumina or carbon fibers (for rocket stiffeners). Corrosion problems usually associated with carbon fiber reinforced aluminum is eliminated by use of a thin ceramic paper surface ply that, after co-infiltration, isolates high strength graphite fibers from the environment. The project objectives are: 1) Optimize the matrix alloys for proper cohesion to particulates and fiber reinforcements while maximizing matrix strength; 2) Demonstrate a hybridized ceramic paper surface to graphite fiber cores that, after co-infiltration prevents graphite exposure at surface and eliminates galvanic corrosion; 3) develop a preliminary database for flange and hat band stiffener applications; 4) Demonstrate the Advanced Pressure Infiltration Casting (APIC™) technology by prototype manufacturing working flanges for the Aerospike fuel duct and demonstration hat band sections for the Space Shuttle nozzle stiffener; 5) The final objective is to demonstrate, through prototype manufacturing, 64% to 87% mass reductions and the cost effectiveness of the Advanced Pressure Infiltration (APIC™) process.
Potential Commercial Applications (Limit 200 words)
Potential Commercial Applications include low mass airframes, commercial space craft components, electronic packaging and space thermal management as well as automotive and sporting propulsion applications. Sports equipment such as golf clubs are also potential applications for derivations of this technology.

Project Title:Hybrid Inorganic/Organic Epoxy Resins Based on Silsesquioxane Cubes for Use in High Performance Fiber Reinforced Composites for Aerospace Applications
Technical Abstract (Limit 200 words)
NASA has an ongoing need for new polymeric materials which possess high mechanical strength, high impact resistance, stability over a wide range of extreme temperatures, and resistance to intense UV and ionizing radiation. We propose the use of silsesquioxane hybrid resins ([(RO)SiO1.5]8, where R is an epoxy or amine terminated organic group] in combination with commercial epoxy resins (DEGBA and TGMDA) and polyamine hardeners (1,6-hexanediamine, diaminodiphenylsulfone, and piperazine) as high performance thermoset polymers for use in fiber reinforced composites (FRCs). Such hybrids would combine the ease of processing (for which thermoset epoxies are known) with properties enhanced by the direct incorporation of robust (SiO1.5)8 clusters into the polymer backbone, resulting in high thermal and chemical stability, high mechanical strength, and increased resistance to atomic oxygen and UV radiation. Our objective for Phase I is to demonstrate that enhanced performance FRC?s can be fabricated using silsesquioxane resins as major thermoset components. To achieve this we will 1) study the curing behavior of silsesquioxane resins with commercial epoxy resins and hardeners, 2) prepare a library of thermosets with varied compositions, 3) test the tensile strength, impact resistance, and thermal stability of the thermosets, and 4) fabricate chopped glass fiber/resin composites using thermosets which showed the best mechanical and thermal properties. In Phase II we will further optimize the thermoset formulations, investigate other fibrous components (i.e., ceramic fibers), and expand the scope of silsesquioxane resins into other potential uses such as advanced adhesives and coating materials.
Potential Commercial Applications (Limit 200 words)
The composite materials that will be developed in this program will be relatively low cost compared to all other high temperature resin materials commercially available. Because of this, it is anticipated that composite products made with these resins may be able to penetrate markets heretofore not possible with these materials. This includes many sports applications, some automotive engine components and if we succeed in making transparent materials, safety applications related to face shields. In addition, upon proper formulation, our materials can likely enhance the properties of epoxy resins used in many other applications, including adhesives and coatings.

Project Title: This proposal has not been assigned a title Advanced Low Density Tooling and Fabrication Processes for Reusable Launch Vehicles
Technical Abstract (Limit 200 words)
NASA launch vehicles such as X-33 and X-34 depend largely on composite technology to reduce launch weight. Composite cryogenic tanks have been fabricated and tested for liquid hydrogen storage (DC-XA Clipper Graham), but new innovations are required to produce LOX compatible composite structures. Innovative technologies are proposed herein to form LOX compatible liners for composite lines, ducts and cryotanks, The liners are produced in conjunction
with lightweight tooling foam mandrels which greatly reduce the weight of composite structure fabrication. The LOX compatible liners are applied either directly on foam mandrels and then overwrapped, or the liner can be appplied internally to the composite structure. Innovative thermal spray processes are used to form the liners out of non-metallics (i.e., fluoropolymers - FEP) and metal (i.e., aluminum). Tooling foam formulations will be demonstrated that dramatically reduce tooling cost and weight.
Potential Commercial Applications (Limit 200 words)
Applications include cryogenic storage vessels, ducts, manifolds, brewing tanks, water storage tanks, fuel oil and hot water tanks, medical and residential oxygen tanks, gas cylinders, hazardous waste containers, and protecting spacecraft from atomic oxygen. Tremendous potential in tooling for molds, mandrels, dies, and complex free form metal components near net shape.

Technical Abstract (Limit 200 words)
A new concept for thermal barriers will be investigated. Thin refractory composite shells bonded to graphite substrates will be developed to create a low cost and high performance thermal protection system. A well characterized refractory continuous fiber composite that demonstrates excellent properties for reusable thermal protection systems will be used for the thin shell material. The fiber is very expensive making techniques that minimize the usage of the fiber attractive. Techniques for fabrication of curved thin composite shells and for bonding to graphite and carbon-carbon composites will be developed in Phase I. Characterization and applicaiton oriented testing will be performed to verity feasibility of the proposed concept. The effort will be supported by computer based design analysis. In Phase II the fabrication procedures will be applied to complex surfaces and and larger components.

New In-space Cured Preceramic
Material
Technical Abstract (Limit 200 words)
The objective of this proposal is to develop a
preceramic polymer which can be used to make
flexible composite materials for future designs of
inflatable spacecraft. The uncured flexible
composite can be folded or rolled into a small
volume for transportation to space. It can then be
expanded in space and cured by UV or under
reduced pressure into a rigid fiber/polymer matrix
composite. The fiber/polymer composite is expected
to be strong enough for use as a space structure
material that is durable and erosion-free in the
space environment. The cured fiber/polymer
composite can be used to make the thermal
protection system for space sample return capsules.
During Earth entry the fiber/polymer matrix
composite will form a high temperature
fiber/ceramic composite.
* A silicon based preceramic polymer system will
be synthesized.
* Verification of curing methods will be conducted
by UV irradiation under reduced pressure or by
reduced pressure alone.
Fiber/polymer composite will be prepared and
curing study will be performed. These tests are
crucial in determining successful transportation,
expansion, and curing methods.
Potential Commercial Applications (Limit 200 words)
This material developed will be used for sample
return capsule from space. It also will allow for
possible in-space construction, repair and
maintenance of future space labs, stations, and
commercialized space vehicles. If the concept is
workable, it will provide a much needed and
innovative approach to volume considerations in
space transportation and structural assembly in
space.
The material developed needs only ambient
temperature and pressure curing from flexible to
rigid structure. It will have numerous applications
on Earth and can replace the present epoxy,
phenolic composites for sports equipment, boat,
automobile and building constructions etc.

Project Title: Low-Cost Surface Enhancement Method for Improved Fatigue Life of Superalloys at Engine Temperatures
Technical Abstract (Limit 200 words)
Surface enhancement, by shot peening or laser shock peening (LSP), improves the fatigue life of monolithic nickel-base superalloy turbine engine components by inducing a compressive surface layer. LSP achieves deep compression with low cold work, resistance to thermal relaxation, and superior fatigue life, but is expensive, and difficult to perform. Low plasticity burnishing (LPB) produces compression, cold work, and resistance to thermal relaxation comparable to LSP. LPB is rapid, inexpensive, and easily adapted to existing machine tools.
The feasibility of LPB surface enhancement of superalloys turbine engine components will be established in Phase I. Residual stress and cold work distributions will be measured before and after exposure to engine temperatures. High cycle fatigue life and thermal relaxation will be compared to shot peening and LSP. Tool life and processing costs will be established. LPB will be demonstrated on NASA superalloys. Successful completion of Phase I will provide a low-cost alternative to LSP for fatigue life enhancement which will be developed for specific applications in Phase II.
Potential Commercial Applications (Limit 200 words)
Low plasticity burnishing (LPB) provides a low-cost processing alternative to laser shocking (LSP) for improving the fatigue life of superalloy turbine engine components. LPB is a practical, cost effective, means of surface enhancement, producing deep stable compression in local high-stress areas of fatigue critical parts. The moderate cost and ease of implementation promise a broad range of commercial applications.
It is anticipated that LPB will be incorporated into manufacturing operations by turbine engine manufacturers and overhaul facilities. LPB tooling will be marketed for existing machine tools for incorporation into manufacturing operations and overhaul facilities.
Applications to superalloy turbine engine components include: leading edges of turbine blades and critical disk surfaces, dove tail features and slots, seal teeth, and other fatigue critical locations.
Beyond superalloys, potential turbine engine applications include titanium alloy fan and steel engine components, and the corresponding components of land based steam and gas turbines. Potential airframe applications include aluminum,
titanium, and steel structures. Automotive applications include gears, bearings, shafts, and springs.

Project Title: High Oxygen Affinity Doping of Boron Nitride Fiber Coatings for Tough, Durable SiC/SiC Composites
Technical Abstract (Limit 200 words)
Boron nitride (BN) fiber coatings have shown promise for toughening continuous fiber-reinforced SiC/SiC composites. However, these fiber coatings sufferfrom oxidative instability, particularly in high moisture containing environments as would be encountered in combustion environments. This instability adversely affects the composite lifetimes thereby limiting the utility of ceramic composites for high temperature, long life applications. Recent research at NASA has indicated that the stability of BN fiber coatings may be improved via silicon doping. Dopant affinity for oxygen is believed to be the reason for the marked increase in stability of the fiber coating. Development of BN fiber coatings containing dopants with even greater oxygen affinities would dramatically further the stability of the boron nitride fiber coating and subsequently improve the lifetimes of ceramic composites in combustion environments. Boron nitride fiber coatings doped with aluminum and titanium will be developed utilizing chemical vapor deposition (CVD) techniques. Tensile properties of SiC/SiC composites containing these fiber coatings will be evaluated at room temperature and elevated temperatures utilizing single-strand minicomposites as a screening technique. SiC/SiC composite panels containing promising variants of the doped BN fiber coating will be fabricated and tested. Successful development of an environmentally durable fiber coating that also provides oxidation protection of the reinforcing SiC fiber is a critical technology to the successful implementation of ceramic composites in high temperature, long life applications.
Potential Commercial Applications (Limit 200 words)
The development of advanced ceramic matrix composites with enhanced high temperature durability performance over currently available systems would directly support a number of NASA, DoD and DoE progrmas such as the High Speed Civil Transport (HSCT) or the integrated High Performance Turbine Engine Technology (IHPTET) demonstrator. Near term applications for CMCs could include replacement components for existing axisymmetric turbine engine augmentors (e.g. divergent flaps and seals). Advanced air-breathing propulsion systems for hypervelocity aerospace vehicles are potential intermediate term applications. Programs are in place for evaluating CMCs for land-based turbine components, catathermal combustion devices, heat exchangers, and radiant burners, which represent opportunities in energy and pollution abatement technologies that may mature over the next ten years.

A PMR Nanocomposite Resin Matrix
Technical Abstract (Limit 200 words)
Advances in fiber-reinforced high performance
composites have led to superior fiber technology
that has not been matched by improvements in the
resin matrix. The high temperature applications of
composites remain limited by the thermal stability
of the resin. The objective of this SBIR project is to
develop a new class of hybrid organic/inorganic
thermosetting PMR (in-situ polymerization of
monomeric reactants) resins for high-temperature
applications. In these materials, the inorganic
component is chemically bonded into the organic
matrix; it becomes an integral part of the resin and
participates intimately in improving the thermal
stability and toughness of the polymer composite,
essential properties of materials used in high
pressure and high/cryo temperature environments.
TDA Research, Inc. (TDA) has developed a
high-temperature resin that combines the
advantages of organic polymers, ceramics and the
engineered composites technology. In addition, the
proposed hybrid monomers provide a safe and
inexpensive substitute for the carcinogenic amines
currently in use. Potential applications for this
technology include molded components for the
aerospace industry, military and commercial
aircraft such as re-entry vehicles, missiles and
airframes. Other applications include automobile
engine components and industrial high-temperature
adhesives.

Project Title:
Ceramic Matrix Composites for
Spacecraft Propulsion
Technical Abstract (Limit 200 words)
On-board liquid rocket motors are presently used in
almost all NASA, military, and commercial
spacecraft for apogee insertion, maneuvering, and
station keeping. Present motors use film cooled
niobium nozzles coated with an oxidation resistant
disilicide layer. These nozzles are limited to a
maximum temperature of 1370C (2500F)and often
fail prematurely due to spallation of the coating.
Ceramic matrix composites (CMCs) offer improved
nozzle materials since they exhibit significantly
lower densities, higher maximum use temperatures,
and better oxidation resistance. These properties
lead to more efficient nozzles resulting in motors
with greater payload, range, and/or lifetime. The
use of CMCs offers the rocket motor designer
many additional variables for use in the
optimization of the nozzle. For example, the CMC
can be used as a non-structural, oxidation resistant
liner, or as a free-standing integrated combustor,
throat, and exit cone. The fiber architecture for the
CMC can be manufactured using braiding, weaving,
filament winding, or involute constructions.
Potential matrix materials include a variety of
carbides, borides, and oxides, and the carbon
reinforcing fibers can be made from PAN, pitch, or
rayon-based precursors. One way to develop a
CMC nozzle, a method that has been used with
limited success, is to qualitatively choose the
constituent materials and design concept, and then
fabricate and test a design. An alternative method,
proposed here, is to quantitatively evaluate
potential designs based on models that have proved
accurate for C/HfC rocket nozzles and leading
edges, and to select the designs that are
theoretically most attractive. These rationally
chosen designs can then be fabricated,
characterized and tested in a Phase II program that
integrates the best combination of material
fabricator, nozzle designer, and component tester.
Potential Commercial Applications (Limit 200 words)
The results of the Phase I effort will be two or three
CMC material designs that optimize the
performance of spacecraft liquid propulsion nozzles.
These designs will be fabricated and characterized
in Phase II leading to spacecraft with greater
payload, range, or lifetime. Designs that are useful
in NASA systems are also directly applicable to
commercial communications satellites built by
Hughes, Loral, and Lockheed Martin, companies
with which MR&D has long-standing business
relationships. Additionally, the technology
developed on this program is directly applicable to
the Integrated High Performance Rocket
Propulsion Technology (IHPRPT) program.
Materials developed here are also of interest to
NASA and to the Defense Department for
applications such as leading edges for hypersonic
airframes.

Torque Limited Touchdown Bearing
System for Magnetic Bearings
Technical Abstract (Limit 200 words)
Magnetic bearings in space applications must have
mechanical backups for operation during launch and
for fail-safe operation while in service on station.
We propose a system in which preloaded ball
bearings support rotation during launch and then
stop when the magnetic bearing control loop is
activated. They will accelerate from rest during
subsequent shock touchdowns and then stop again.
Acceleration will be limited in the ball bearings to
prevent ball-race damage from gross slip. Torque
limitation will be provided by a solid film lubricated
bearing and a fluid journal bearing in series with the
ball bearings. In Phase I of this SBIR, the objective
is to accumulate a body of experimental
shock/damage data that will define the acceleration
limit for the system.
The subtopic requirement addressed is to extend
life of mechanical components under Machinery
Dynamics/Advanced Bearings/Magnetic Bearings.
NASA will benefit from this program by being able
to use magnetic bearings reliably in any space
application.
Potential Commercial Applications (Limit 200 words)
The development of a reliable magnetic bearing
system to support very high speed rotors has
tremendous potential for the space community. The
touchdown system proposed in this SBIR will allow
launch operation, sustain all shock loads, and a
general failure of the support system, thus
removing the major impediment to magnetic
bearings in space applications.
Reaction/Momentum Wheel manufacturers, who
are now developing magnetic bearngs, but who lack
a reliable and fail-safe touchdown system are prime
customers for this technology. With the current
proliferation of satellites, the cost advantage of a
magnetic bearing/fail-safe touchdown system will
make this concept very attractive.
TBC will ultimately plan to market Torque Limited
Touchdown Bearing Systems suitable for other
magnetic bearing applications: energy storage
systems for automobiles and buses; small factories;
aircraft gas turbine engines; air cycle machines,
etc.

Technical Abstract (Limit 200 words)
A unique fluid film journal bearing concept called a

Modifications of an engine required for installation
of the Wave Bearing will also be designed in Phase

The Wave Bearing concept has promise of
providing a journal bearing solution to the higher

gas turbine engines. In addition the Wave Bearing
promises to be lower in both initial and operating
cost when compared to presently used ball and
roller bearings. The potential, therefore, is for use
of Wave Bearings in gas turbine engines for both
terrestrial and aircraft applications.

Multiphysics Simulation for
Aeropropulsion Systems Using Smart
Structures
Technical Abstract (Limit 200 words)
The development of aeropropulsion components
that employ "smart" materials with embedded
piezoelectric actuators has great potential to
ameliorate destructive problems such as vibration
and aeroelastic instability. To aid the development,
numerical simulations of the aeropropulsion
systems with embedded smart structures is
desirable. However, the analyses are inherently
multidisciplinary characterized by coupled
aerodynamics, structural response, electric charge,
and material properties. This proposal addresses
the need for coupled simulation of these
multidisciplinary phenomena by developing a
multiphysics finite element analysis software. The
innovation proposed herein is the direct coupling of
compressible flow and smart structure simulation
using a common framework that enables further
understanding of the smart systems. Traditional
approaches handle interactions by solving single
disciplines in a sequential manner with information
passed through a data translation. The single
physics approach can be lengthy, tedious and often
times inaccurate. The proposed work will relieve
these drawbacks, and permit a new class of
problems to be analyzed at higher levels of fidelity
than previously possible.
Potential Commercial Applications (Limit 200 words)
Potential applications of this product are in the
design of aircraft engines and turbomachinery in
general. Simulation of active materials such as
piezoelectric actuators to suppress vibrations,
aeroelastic instability, and noise emissions can lead
to reduced design-to-production time and improved
operation life-cycles.

Project Title: A Robust COnstitutive Material PARameter Estimator (COMPARE) for Characterizing General Nonlinear Material Models
Technical Abstract (Limit 200 words)
The DIAgnostic and integrated Problem Solving (DIAPS) Engineering team proposes to develop an automated, systematic, and computationally effective methodology to estimate material parameters for characterization of general compressible/incompressible mathematical material models for large deformation schemes (e.g., hyperelasticity, elastomeric foam behavior). Such constitutive models often require a large number of material constants to describe a host of physical phenomena and complicated deformation mechanisms. Extracting such material parameters for a model from the volumes of data generated in the test lab can be a frustrating task. The integrated COnstitutive Material PARameter Estimator (COMPARE) will enable the design engineer to predict an optimum set of material parameters by minimizing errors between the experimental data and the predicted response. The key ingredients of COMPARE are: (i) primal analysis tools (response functionals) for the differential form of constitutive models, (ii) sensitivity analysis, (iii) optimization of an error/cost function, and (iv) a graphical user interface. COMPARE formulates the material parameter extraction problem as a minimum-error, weighted, multi-objective optimization problem. Preliminary results from test data analysis of a certain class of viscoplastic and hyperelastic materials clearly demonstrate the great potential for COMPARE as a tool for material parameter estimation.
Potential Commercial Applications (Limit 200 words)
Demand for an automated material parameter estimator would be enormous in those industries that look to the finite element method to support product design. The most efficient means of bringing COMPARE to market , therefore, would be to offer it through those companies which specialize in developing finite element codes. We envision companies like the MacNeal-Schwendler Corporation (and their MSC/NASTRAN code) as our primary target for commercialization.

Project Title:
Terbium-Doped Optical Fiber
Scintillating Radiation Detector
Technical Abstract (Limit 200 words)
Future spacecraft traveling from earth to orbiting
space stations and planets must be able to
withstand extended exposure to energetic photons
and particles encountered during space missions.
High levels of radiation exposure have the
capability of injuring human occupants and
damaging sensitive electronics such as computers
and communications equipment. In addition, future
satellites (i.e. Iridium) will need small compact
sensors to detect radiation events in real-time, such
as solar flares, which expose them to high levels of
radiation and can potentially damage them. A
passive, lightweight fiber optic radiation sensor is
proposed to monitor the space environment for the
existence, and time of exposure, to ionizing
radiation. The unique design of the compact sensor
allows it to be placed in remote locations, allowing
signal processing to be done safely in shielded
areas. Other advantages of this detector over
conventionally available radiation detectors are
omni-directional detection capability, broadband
energy detection, small size, radiation hardness,
and low electrical power requirements. The
development of this sensor will provide NASA with
a low cost radiation sensor that can be reconfigured
for various space missions.
Potential Commercial Applications (Limit 200 words)
The proposed photon detection system has strong
commercial applications in food irradiation, toxic
waste monitoring, and radiation monitoring of
commercial space vehicles. The passive nature of
the sensor allows it to be placed close to the
radiation source and performs measurements that
can be monitored from a remote location thus
ensuring operator safety.

Project Title:
Modern Method for Computing
Contamination
Technical Abstract (Limit 200 words)
We propose to develop a suite of PC/workstation
programs (CCON) that greatly improve
contamination-prediction procedures. CCON will
reduce computation times by a factor of 10 to 1000
and engineering time by a factor of 2 to 4. CCON
will also be more user friendly. Several innovations
give CCON its advantages: (1) a powerful but
inexpensive graphical method for developing the
model either independently or from CAD, thermal
or structural models; (2) a method for modifying
models from other disciplines to meet the modeling
needs of the contamination discipline; (3) an
automated method for importing thermal data into a
contamination model that differs geometrically; and
(4) a much faster version of an industry-standard
simulation program. CCON addresses directly
NASA's 20.05 topic: Space Environmental Effects
and Contamination under subtopic
" mass-transport models to predict molecular
direct-transfer, backscattering, particle transport,
and surface effects." The innovation would become
part of our company's software product line. NASA
and industry will benefit by the less costly, more
thorough models generated by CCON, and by
response times for contamination analyses that
permit the contamination technology to participate
more interactively in the design effort.
Potential Commercial Applications (Limit 200 words)
The innovation would become part of our software
product line. NASA will benefit by the less costly,
more thorough models generated by CCON, in part
because of great increase in computational speed
and the great decrease in engineering effort and in
part because the contamination technology will, as a
result of the proposed work, be able to respond
quickly enough to be an integral part of the design
team. Commercial space companies will similarly
benefit from the product of this work. The vacuum
industries, such those using vacuum vapor
deposition and vacuum pumping, are also potential
purchasers of the software.

Project Title: Open Atmosphere In Situ Processing of Thermal Control Thin Films for Spacecraft
Technical Abstract (Limit 200 words)
Presently, quartz optical solar reflectors (OSRs) are used to provide desired absorbance and emissivity properties to the exteriors of satellites. While a reliable and proven solution, OSRs are expensive and application is limited to flat surfaces. One possible solution identified years ago was thin film depositions. It has been demonstrated that thin films generated by chemical vapor deposition can provide desired absorbance and emissive properties comparable to OSRs. However, traditional vapor deposition techniques require a costly high temperature reaction furnace and/or vacuum chamber limiting their widespread use for this application. With the capability to deposit inexpensively in the open atmosphere, the Combustion Chemical Vapor Deposition (CCVD) process has demonstrated the capability to deposit desired materials, such as Ag and SiO2, onto large and irregular surface areas. With a viable thin film deposition method, the weight reduction should be up to 80% versus OSRs. As a result, the CCVD technology offers a viable and compelling solution to address the needs of future spacecraft requirements.
Potential Commercial Applications (Limit 200 words)
Upon completion of the research contemplated in this Phase I, MCT will have developed a thin film oxide coating for use as a replacement for OSRs. Additionally, a prototype system will be designed for application of this coating using CCVD technology. In doing this, MCT will be uniquely positioned to capitalize on the $100M+ market for OSRs. With the current direction of industries headed environmental safety, CCVD can provide non-toxic processing, increased operational efficiency, and continuous coating onto large and irregular surface areas. Using Phase I and II award funding as support, the commercial objective of this proposal is to create a new, industry-wide standard process for environmentally safe production of these thin film coatings deposited via the CCVD process and then to place the process into commercial use as part of Phase III.

Piezoelectric Polyphenylene Materials
Technical Abstract (Limit 200 words)
Maxdem scientists have developed proprietary
technology that allows for the preparation of a wide
variety of substituted polyphenylene derivatives.
These polyphenylene materials offer many
attractive features including excellent mechanical
properties, excellent thermal stabilities, and facile
processabilities. In addition, the properties of these
materials are easily modified by varying the
substituents attached to the polymer backbones.
In this program, the development of a new class of
piezoelectric materials based on functionalized
polyphenylene polymers is proposed. These
materials contain polar substituents that are known
to align in the presence of an electric field. It is
anticipated that the substituted polyphenylenes
proposed in this program will offer use
temperatures of 150-200oC, along with piezoelectric
responses comparable to PVDF. At least eight
different substituted polyphenylene polymers will
be prepared and characterized at Maxdem. Films of
these materials will then be sent to Dr. Joycelyn
Simpson of the Composites and Polymer Branch of
NASA Langley to have their piezoelectric
responses evaluated.
Potential Commercial Applications (Limit 200 words)
Piezoelectric polyphenylenes could lead to a wide
variety of smart devices including active noise and
vibration controllers; micromachined devices that
integrate sensor, signal processing, and control
circuits; smart windows and display technologies;

Project Title: High Thermal Conductivity C-C Composites For Chip-On Structure
Technical Abstract (Limit 200 words)
C-C composites offer excellent thermal, mechanical and outgasing properties. Their commercial application in electronics is extremely limited due to their high cost. MER has developed a new process, which has the potential to produce C-C composites at $50/lb. This proposal seeks innovative solutions to extend this new technology to space applications, by providing dual (structural, electronic) usage of low CTE C-C composite optical benches. Novel approaches are sought to address the issue of strain isolation (CVD carbon) and dielectric insulation (polymeric coating). It is anticipated that this new technology will provide clear advantage over printed wiring boards (PWB?s) in chip-on-based applications.
Potential Commercial Applications (Limit 200 words)
The low-cost, C-C composite based integrated substrate has enormous (over $1 billion) applications in microelectronics such as chip-on-board (COB) and multi-chip-module-laminate (MCM-L). Specific applications include portable electronics, micro processors, and commercial avionics.

Project Title: Isotropic Low CTE C-C Composites
Technical Abstract (Limit 200 words)
Low density/reduced mass materials with a low coefficient of thermal expansion (CTE) have many applications in a variety of aerospace systems. Low cost manufacturing is enabling to the utilization of these materials. Carbon-Carbon (C-C) composites meets the low mass requirement, but has an isotropic CTE and is prohibitively expensive. Through the selective use of graphite reinforcements in un;ique architectures along with unique matrix/binder formulations, it is possible to produce C-C composites for less than $50/lb. with an isotropic CTE at or near zero. The concept of low cost low CTE C-C composites has been initially demonstrated. This program will optimize formulation and processing to produce low cost C-C composites with an isotropic CTE at or near zero.
Potential Commercial Applications (Limit 200 words)
In addition to mirror and instrument mounts as well as mirror blanks, isotropic zero to near zero CTE C-C has applications for a plethora of applications in electronics including substrates or boards and anyplace where dimensional control and/or light weight is important, including enginie components.

Project Title: Out-of-Autoclave Processing of High Performance Composites
Technical Abstract (Limit 200 words)
This project's primary objective is to demonstrate a unique means of pre-forming and curing composite parts; while providing the same strengths as obtained with current fabrication methods. The innovation of this proposal is the development of matrix resin systems that enable tow prepregs to be molded by ATP in seconds, at low temperature and pressure, on relatively inexpensive tooling. The proprietary matrix enables the parts to retain shape and compaction after removal from the tools allowing a freestanding unrestrained) cure by E- Beam or oven. This process could provide cost savings up to 50% compared to current fabrication methods. Aerospace structures will benefit from lower acquisition costs and, with EB cured composites, lower residual stresses. In Phase I, API will create formulation models for characterization and down selection to the two best candidates. The two will be made into net shapes and cured unrestrained, one in an oven and the other by E- Beam radiation at room temperature. In Phase II, the EB and thermal cure methodologies will be fully compared, down selected, optimized, and tow preg manufactured for part fabrication on an ATP robotic arm. If EB selected, a low energy generator will be designed on the robotic arm for resin advancement.
Potential Commercial Applications (Limit 200 words)
Polymer-matrix structures such as fairing, spoilers, flaps, and rudders have been used for some time in both and civil and military application. High cost has been the main impediment to more widespread usage. Lower acquisition osts will potentially expand the aerospace applications to such as wing boxes and horizontal and vertical stabilizers. Polymer-matrix structures may become cost effective for non-aerospace markets such as high-speed marine and rail vehicles. A promising niche market would be spacecraft structures especially with E-Beam cure where the dimensional stability would be enhanced. New polymer-matrix systems as envisioned in this proposal will increase the cost effectiveness of ATP (Automated Tow Placement) and E-Beam equipment.

Project Title:
An Eddy-Current Inversion Algorithm
for Aerospace Structures and Materials
Technical Abstract (Limit 200 words)
The ability to solve inverse problems lies at the
heart of electromagnetic nondestructive evaluation
(NDE). These problems are difficult to solve for two
reasons: they are mathematically ill-conditioned,
and they are nonlinear, which means that they
involve considerable computational effort, often
requiring supercomputer capabilities. In this
proposal, we describe an inversion algorithm for
electromagnetic (eddy-current) NDE that will run
on a wide class of machines, from personal
computers and workstations to minisupercomputers
and larger machines. Furthermore, we expect an
improved robustness that will mitigate the effects of
ill-conditioning. The algorithm employs modern
mathematical ideas of set theoretic estimation and
robust statistical analysis.
The technology that we are developing in this
project will be applicable to the detection, imaging,
and characterization of flaws and other
integrity-reducing anomalies in aerospace
structures and materials. In particular we will apply
it to (a) the detection and characterization of metal
corrosion in hidden or inaccessible airframe
locations before significant material-loss has
occurred, (b) the detection and characterization of
cracking and multisite damage in metallic airframe
structures, (c) the characterization and qualification
of advanced materials for use in the repair and
retrofit of aging systems, and (d) the detection,
imaging, and characterization of surface and bulk
anomalies in metallic and nonmetallic airframe
structures or engine components.
Potential Commercial Applications (Limit 200 words)
The aging aircraft problem is one of the most
serious matters faced by airlines in the United
States. Air transportation is a multi-billion dollar
industry world-wide, but until it utilizes
sophisticated computational NDE techniques of the
type proposed herein, it faces a very grim prospect
for economic survival. If our research is successful,
then we will be able to provide to this industry a
reasonably-priced solution to this problem. The fact
that our software is able to solve complex, realistic
problems efficiently on personal computers and
workstations guarantees a commercial market for
it.
There are other segments of this market, such as:
NUCLEAR POWER. One of the critical problems
in nuclear power plants is detecting and
characterizing integrity-reducing flaws in heat
exchanger tubes. This amounts to solving an
inverse problem of the type that we will study
during this research.
CIVIL INFRASTRUCTURE. An estimated 35% of
the nation's bridges are structurally deficient or
functionally obsolete. Corrosion of rebar in
concrete bridge structures is one of the contributing
factors to bridge degradation, and a range of
nondestructive inspections techniques, including
microwaves, are being actively investigated by
researchers.
MEDICAL IMAGING. The inversion algorithms
that we will develop can be applied, in some cases,
to the problem of medical and dental imaging and
diagnostics.
MATERIALS PROCESSING. In the manufacture
of conventional metals, one must assure that
prescribed qualities have been maintained, such as
the correct heat-treatment, or the correct state of
stress reduction. This requires the solution of
inverse problems. This holds, also, for the
metrology of thin-films, such as appear in the
manufacture of memory chips and other
semi-conductor components for computers.

Project Title: An Infrared Microspectroscopy Imaging System
Technical Abstract (Limit 200 words)
With the advent of tunable mid-infrared lasers it now becomes possible to capture spectral data using IR detector arrays. The resulting images would provide a spatial map allowing measurement of optical absorption, reflection or transmission as a function of avelength. We propose to exploit this capability by developing a new infrared microspectroscopic imaging system (IMIS) that provides both high spectral and spatial resolution. Such a system could be used to characterize the spatial variations in a specimen?s chemical structure, detect the presence of contaminants, and provide very sensitive surface displacement measurements using an optical technique known as shearography. The proposed system would consist of a tunable mid-IR laser configured for the 1.4 to 5.0 micron wavelength range and a high-resolution, long-working-distance thermal analysis microscope capable of 10-micron resolution.
Potential Commercial Applications (Limit 200 words)
Potential commercial applications include identification and control of contaminates during manufacturing processes such as semiconductor fabrication, observing chemical and structural changes in polymers and paints during the cure cycle, monitoring the ply-to-ply or fiber-to-matrix bond quality in composite materials, measuring oxidation rates and identifying oxidation products, and measuring the relationship between temperature and chemical reaction rates.

Project Title: Transparent Polymeric Bremstralung Radiation Shield for Space Welding
Technical Abstract (Limit 200 words)
Astronauts performing e-beam welding during space assembly EVA operations are subject to health-damaging secondary gamma and X-ray radiation called Bremstralung. Normal protective shields are metal and are not optically transparent. Triton is developing a transparent COR (clear AO resistant) polymer that will absorb Bremstralung by the unique molecular level incorporation of heavy metal salts within the polymer film. We propose here to develop a new COR-BA (Bremstralung Absorbing) 10 mil thick transparent shield, through which the astronaut can see to perform EVA e-beam welding in space, with the shield offering protection from the damaging effects of Bremstralung radiation. Triton computer simulations show that a 10 mil COR-BA film will absorb 98 % of 10 KeV X-Rays and 100 % of 5 KeV X-Rays, while still allowing the astronaut to see through the shield with X-ray protection. In Phase I, Triton will build sample COR-BA shields and test them for Bremstralung radiation protection and for optical transparency. In a Phase II Program, Triton will build optimized COR-BA shields in larger sizes needed to protect astronauts during a welding operation. Superstructure and support of the COR-BA shield will be developed. A space test of a small shield during Phase II is anticipated. In a Phase III Program, Triton, with a space manufacturer, would produce COR-BA protective shields for use in space welding operations.
Potential Commercial Applications (Limit 200 words)
Triton Systems anticipates that as a result of this Phase I program, new gamma and x-ray absorbing, transparent polymeric materials will be developed. Anticipated benefits include significantly improved safety for space e-beam welding operations, and potential for inflatable space habitats that protect against X-Rays and gamma rays produced during solar flares. The commercial applications are specific to providing a safe working space environment whose benefits are a healthy and well protected astronaut.

Braze Joining of SiC Composite RLV
Propulsion Components
Technical Abstract (Limit 200 words)
Joints between very dissimilar materials - e.g.
metal-to-ceramic, are required in a number of
aerospace, commercial and industrial systems.
Brazing is often the preferred joining technique
owing to compatibility, performance, cost and
scalability advantages. However, the traditional
brazed dissimilar material joints are likely to have a
relatively low strength because of the high residual
stress in the joint region. Also, brazing compounds
frequently use active metal additions to promote
wetting of the adherend surfaces. Though active
metal additions do increase the joint strength in the
short term, it has been shown that under elevated
temperature operation, the joint strength falls with
time. Foster-Miller's unique braze joint concept
approach overcomes both brazing problems.
During Phase I, Foster-Miller will demonstrate an
innovative, practical and low cost brazing
technology for elevated temperature RLV
propulsion components. The Phase I program will
involve selection of materials to be joined with input
from NASA COTR, design and build-up of the
braze product form, fabrication of joint coupons, and
testing consisting of physical characterization and
mechanical, thermal cycling. The follow-on Phase II
program will involve refinement of design,
materials, procedures and process parameters.
Phase II joint coupons will be subjected to a
comprehensive test plan. A demonstration article of
specific interest to NASA will be built during Phase
II. The Phase II program will involve the following
commercialization partners - braze product
manufacturer, brazing service provider, NASA
systems integrator.
Potential Commercial Applications (Limit 200 words)
Brazing is commonly used for joining of metallic and
ceramic materials. The proposed technology has
commercial applications involving attachment of
dissimilar materials. These include: compact
furnace components, hypersonic plane structures,
rocket and gas turbine engines, X-ray and
semiconductor sputtering targets, and industrial
applications such as attachment of tubular products
in pipelines, heat exchangers, chemical, oil drilling
and mining slurry transport tubes, etc. Additionally,
a reliable, practical and low cost joining technique
for dissimilar materials will provide a new
dimension for reducing component cost for
designers, e.g. use different materials in strategic
regions of a component.

Project Title: Compliant Pad Bonding for Space Shuttle Evaporator Furnace Technical Abstract (Limit 200 words)
In this program, General Systems is proposing to develop a furnace design which will include developing high temperature joining of graphite, molybdenum and alumina for use in evaporator furnaces for experiments on Space Shuttle and Space Station. Our design will not use any active, transition metal brazes, use a compliant pad to accommodate differential CTEs and also utilize a ceramic coatings on graphite for oxidation and fire protection. Our innovation will combine the use of high temperature braze such as nickel and palladium with a refractory metal compliant pad to accommodate the shear strains to off-load the high thermal stresses and will result in a mechanically strong joint. We will eliminate use of transition metals via use of innovative metallization of the carbon. We will also use refractory ceramic coating on the graphite to minimize possibilities of fire hazard in case of an accident. In the Phase II program we will fabricate and deliver to NASA ultra-compact furnaces for use as particle generators for space shuttle and space station experiments. We will also commercialize the compliant pad bonding technology in power electronics packaging and aerospace industries.
Potential Commercial Applications (Limit 200 words)
Bonding of dissimilar materials is necessary for use in aerospace engine components such as aerospike engine of reusable launch vehicles, use in high power electronic package for packaging SiC, GaAs and GaN devices.

Project Title: Laser welding, bonding and joining using diffractive optical elements
Technical Abstract (Limit 200 words)
NASA has expressed a need for innovative technologies for bonding and joining of materials to improve the performance and affordability of future aerospace systems. Methods of forming strong bonds between different aluminum alloys, as well as between dissimilar refractory metals and ceramics, are of key interest. Laser welding techniques are commonly used to join similar materials, such as steel to steel in the automotive industry. However, when dissimilar materials are used, different thermal sheer stresses are introduced at the material junction. These stresses introduce cracking and flaws in the weld and result in inferior joints if standard laser welding techniques are used. The proposed approach makes use of diffractive beam shaping optics to provide different laser intensity distributions on either side of the joint to eliminate these stresses, resulting in stronger bonds between the materials. Beam shaping optics can be used to join metals with ceramic materials using different bonding principles. This Phase I effort will demonstrate the application of beam shaping optics to the welding and joining of dissimilar materials. Both experimental and analytical studies will be used to verify the objectives of the proposed project.
Potential Commercial Applications (Limit 200 words)
This work will provide benefits to a broad range of manufacturing industries. The automotive and avionics industries in particular can make use of the ability to join metals with ceramics and other dissimilar materials to increase the performance and to reduce the weight and cost of their finished product. Similar applications and benefits can be envisioned for uses of lasers in the medical, information processing, and consumer microelectronics industries.

Technical Abstract (Limit 200 words)
Waveguides offer an alternative for providing
transmit/receive communications for spacecraft.
The advantages of the inflatable waveguide
concept, in addition to its light weight and low
packaged volume, is the inherently simpler shape
(flat). Relative to parabolic antennas, the
requirement to make an accurate doubly curved
surface is removed. Langley Research Center

Waveguide Feasibility Study. This program is

However, the purpose of the LaRC study is to
fabricate and test small elements of the waveguide,
with no support structure. Thus, the issue of
deployment remains unanswered. It is the purpose
of this proposed study to design a working subscale
waveguide unit and plan a series of deployment
tests in ambient and/or vacuum conditions. These
experiments will not only benefit the waveguide
community, but also those involved with deployable
SARs, solar arrays, sunshields and solar sails.
Potential Commercial Applications (Limit 200 words)
The deployable waveguide technology offers the
benefits of reduced mass, packaged volume and
system cost. These are improtant drivers for any
mission, government or commercial. The
deployable structure is not limited to waveguides
alone; once developed and tested, the design can be
applied to other applications, including solar arrays,
SARs, sunshields and solar sails.

Project Title:
Inflatable Solar Array Flight Test
Technical Abstract (Limit 200 words)
Under the ARPA-funded Inflatable Torus Solar
Array Technology (ITSAT) program, L'Garde
developed and tested a 275 (BOL) watt
inflatably-deployed solar array. The design consists
of two inflatable-then-rigidized aluminum cylinders
used as the structural members to support a flexible
solar array blanket. During the previous program,
the hardware was designed, fabricated, and taken
all the way through environments and deployment
in a thermal vacuum chamber. A follow-on flight
test program for the ITSAT was planned by ARPA,
but it never occured due to drastic funding cuts at
ARPA. As a result, the hardware developed under
the ITSAT program sits idle, awaiting flight testing.
During this proposed Phase I program, L'Garde will
outline the required tasks to fly the unit, define and
cost instrumentation, plan a meaningful flight
experiment, identify flight opportunities, and plan a
follow-on Phase II program. During Phase II,
L'Garde will perform the refurbishment tasks,
incorporate the desired instrumentation, perform
flight integration tasks with the chosen launch
agency, support the flight test, and perform
post-flight data reduction.
Potential Commercial Applications (Limit 200 words)
Once flown, the applications for the inflatable solar
array are numerous. The ITSAT technology is
currently being considered not only for NASA outer
planetary missions, but as primary power for a
privately funded array of telecommunications
satellites. A successful flight test of the ITSAT will
prove out the technology for future users. In
addition to their use as solar array deployment and
support devices, the ITSAT aluminum rigidized
tubes may also be used for other space structure
elements.

Project Title: High Performance Polymer (TOR-RC)For Space Applications
Technical Abstract (Limit 200 words)
Triton Systems will develop a novel space durable material inherently resistant to AO-UV environments encountered in low earth orbits (LEO). This colorless polymer, designated as TOR-RC, characterized by high mechanical strength and low density, will be both solution and melt processable, providing films and coatings with a combination of properties previously unattainable. Expected applications of this material include reusable inflatable thin film concentrators, thermal control materials for LEO and GEO environments, solar array substrates, antenna reflector/collectors, and multilayer thermal insulation (MLI) blankets. In a Phase I program we will investigate and develop this material with an eye toward efficient scale-up synthesis and cost efficient processing designed to meet present and future materials needs in the aerospace community. The successes of the Phase I will lead to a Phase II which will roadmap the commercial production of TOR-RC for NASA and private sector space markets.
The proposed Phase I SBIR will focus on:
o Optimizing the synthesis of the TOR-RC polymer
o Scaling-up the production of TOR-RC in order to produce multi-pound quantities of polymer to ensure batch to batch reliability and repeatability
o Producing structures based on TOR-RC
o Metallizing rolls of TOR-RC film
o Characterizing the properties of the finished structure, and
o Forwarding prototype structures to potential end-users Potential Commercial Applications (Limit 200 words)
Anticipated benefits of the proposed Phase I research are more reliable and more space durable structures for a variety of commercial and research space programs. New lightweight protective coatings and inflatable structures will be developed for LEO and GEO satellites, spacecraft, and high altitude aircraft. This will lead to more durable space vehicles for both NASA and commercial interests

Ultra-Thin Film Fabrication for
Inflatable Systems and Solar Sails
Technical Abstract (Limit 200 words)
Lightweight, deployable space structures made
from mechanically reliable ultra-thin films have
tremendous potential for enabling lighter, less
expensive space missions. NASA applications for
these films include inflatable antennas, solar
collectors, and space structures, in addition to uses
in solar sails, thermal blankets, and flat film
reflectors. The proposed research will demonstrate
the feasability of continuous roll fabrication of
colorless polyimide ultra-thin films with 1 to 2 µm
thickness that incorporate rip-stop technology,
anti-cling qualities for handling and deployment,
and high refectivity. Also, the fabrication process
will be refined to produce quality control
parameters for consistent and repeatable
continuous film production. In addition, the
mechanical and physical properties of the ultra-thin
films will be measured through standardized lab
tests.
Potential Commercial Applications (Limit 200 words)
The production of continuous roll ultra-thin films
incorporating these advanced features are
commercially applicable to inflatable structures,
solar sails, thermal blankets, flat film reflectors,
and electronic thin film capacitor tissues. The
continuous roll film process provides increased
quality control, smaller film thicknesses, and cost
savings over current thin film technologies in
commercially available.

Project Title: Force-Output Microactuator For Precision Active Optics incorporating a Passive Thermal Release Lockdown Mechanism
Technical Abstract (Limit 200 words)
NASA is evaluating mission critical requirements for future astrophysics missions such as SIM, SIRTF, NGST and NMP. New approaches to optics for high precision angular resolution and figure control are needed to meet these challenges. Although position actuators might meet the requirements for rigid body motions of the deployed primary and secondary mirrors (i.e. edge alignment and tip-tilt mirror control), they are unsuited to flexible-body control of the active optics (i.e. shape control). Acquiring and maintaining the optical figure requires a different solution - force control actuation. Such force output actuators must maintain shape of primary and secondary optics against gravity release, thermal excursion, temperature gradients and structural creep. This proposal aims to develop a force-output actuatorthat will meet NGST active optics requirements during launch, deployment, recalibration and observatory phases of the mission. The design is based upon recent advances in active materials and flextensional actuator design. The design incorporates an optional passive (thermally activated) lock-down mechanism for the primary optics needed for launch that automatically releases without power or complex mechanical interactions.
Potential Commercial Applications (Limit 200 words)
EMF and TRW will be seeking commercial telecommunication satellite application of the proposed technology which require precision alignment to include line-of-sight data transfer. Burleigh Instruments, a worldwide marketer of nonopositioning systems, is interested to investigate with EMF the use of the multilayer-multistack cymbal actuator to enable a new class of larger throw (340um v.200um) higher bandwidth micropositioners. The larger available throw and higher bandwidth of operation (600Hz v. 80Hz) of these devices will benefit optical alignment, micromanipulators and precision translators and create additional markets in lightweight, adaptive optical systems. The ability of the proposed force actuator development to accurately control the figure at high frequency, for ground applications, without inducing local stresses and accomodating local failure, is extremely attractive for commercialization. EMF is exploring such applications with SSG, Inc. and Hughes-Danbury Optical Systems. However, one of the greatest impact could be to early detection and non-intrusive surgery through advances in medical diagnotic equipment.

Project Title: Electromechanical Systems for Spacecraft
Technical Abstract (Limit 200 words)
Individual modules or their combination will be targeted for multiple payload instrument platforms, spacecraft laser communications, and imagers on-board low cost constellation-type satellite busses. Further applications will be in positioning and vibration suppression enhancements to a microprecision vibration isolation product introduced recently for semiconductor manufacturing equipment.
A family of modular electromechanical mounting components for jitter suppression and microprecision pointing on satellites is proposed. The component family incorporates passive vibration isolation, active vibration isolation and suppression, and multiple-axis pointing. These devices will require little or no customization for incorporation early in or late in the payload and spacecraft design cycles, and will be suitable for use by either an instrument developer or a satellite payload integrator. A simple standard mechanical interface and overall component family characteristics will be selected based on a review of existing and predicted needs. The review will address the number of degrees of freedom of isolation and pointing required, and the overall restrictions on mount geometry. The vibration mitigation mounting system will support either vibration-generating or vibration-sensitive components. It will employ zero outgassing passive magnetic technology and piezoelectric actuators. The Phase I effort will include requirements definition, conceptual design, simulation of
satellite-instrument jitter and pointing characteristics, and build and test of a single-axis prototype mount. Phase II will develop the family of devices further with the goal of producing flight qualified hardware for use in a specific NASA instrument mounting application.

Technical Abstract (Limit 200 words)
Physical Optics Corporation (POC) proposes to develop an automultiscopic three-dimensional virtual interactive environment workbench display system in which innovative 3-D displays present distortion-free stereo 3-D images to multiple viewers. In this unique collaborative work environment, a crew of workers see 3-D images correctly located and oriented for each one's view position. Users experience an interactive and cooperative environment for dynamic maneuvering tasks such as engineering design or surgery. POC's simple stereo projection systems based on holographic optics will project the imagery onto a multiplexed holographic projection display screen. Holographic optical elements will produce full-color, high-resolution 3-D images with correct perspective for all viewers, overcoming the drawbacks of current 3-D virtual workbench devices. The system will be compatible with current multimedia and projection display technologies, and can also be adapted to many user-specific, task-related, virtual environments. Phase I research will include a thorough study and demonstration of COVE-3D display concepts, culminating in a prototype device that will display 3-D imagery in correct perspective for two users.

Micro-Electric Propulsion Technology
Technical Abstract (Limit 200 words)
This proposal addresses a low cost, micro-electric
propulsion technology for microspacecraft. The
novel technology proposed can potentially fulfill
NASA requirements to develop a miniaturized
propulsion system in support of microspacecraft
planetary, space physics and Earth science
missions. To overcome the disadvantages and
processing limitations of current electric propulsion
techniques, an innovative micro-electric propulsion
concept is proposed based on electrohydrodynamic
(EHD) emission and acceleration of multiply
charged micro-cluster beams. A primary objective
of the proposed effort, using simulated MEM
micro-cluster emitters, is to demonstrate specific
impulses of = 1000 s using surface tension feed,
valveless operation and temperature control of a
glycerol propellant. Another objective is to
demonstrate that beam neutralization can be
achieved by the simultaneous emission of both
positively and negatively charged micro-clusters. It
is anticipated that by eliminating bulky and power
consuming electron emissive neutralizers,
component miniaturization for future
microspacecraft will be simplified.The approach
presented in this proposal is unique since it
provides the potential to achieve
order-of-magnitude reductions in mass, size and
thrust for micropropulsion components. Moreover,
the micro-cluster approach addresses the MEM's
material compatibility issue and meets the
conditions for potential microspacecraft masses
less than 1 kg.
Potential Commercial Applications (Limit 200 words)
Microspacecraft clusters are being proposed to
provide improved communication services (without
terrestrial links), global cellular telephone coverage
and low-cost message and position-relay services.
Microspacecraft constellations are also envisioned
for remote sensing commercial applications to
manage crops, detect pollution and to aid
meteorological observations for improved weather
forecasting.

Light-weight Reaction Wheels for
Microspacecraft
Technical Abstract (Limit 200 words)
The objective of the Phase I effort is to develop a
Light-weight
Reaction Wheel for microspacecraft using
Micro-Electro-Mechanical
(MEM) technology. The reaction wheel uses a
novel micromechanical
motor to reduce the size and
weight. The micromechanical motor is of pancake
design so its magnet
rotor
doubles as a spinning wheel. It does not have an
iron core thus
eliminating
motor-induced disturbances so yielding higher
pointing accuracy. It
will be
spun on compliant jewel bearings designed to
withstand launch
acceleration
loads, thus facilitating operation in space. The jewel
bearings offer
low
friction thus ensuring long life. In Phase I we will
develop the
design
configuration of the MEM reaction wheel for a
typical microspacecraft.
This will be accomplished by conducting a trade
analysis between the
diameter,
speed and weight. An optimal light-weight MEM
reaction wheel that is
suitable
for Microspacecraft is the end result of this effort.
Potential Commercial Applications (Limit 200 words)
The MEM reaction wheel technology has several
potential commercial
applications. These include robotics, miniature
refrigerators,
miniature fans, pumps, etc. It will also find
application in
commercial satellites for remote sensing,
surveillance and
weather-tracking. The MEM motor developed
herein can also be used in
many markets such as turbomolecular pumps,
auxiliary power units and
air cycle machines.

Recycled-Energy Logic Circuits for
Ultra-Low Power Applications
Technical Abstract (Limit 200 words)
The proposed innovative approach to reducing
power consumption is based on the realization that
most of the switching energy in a digital system
does not have to be dissipated as heat but it may be
recycled.
The objectives of the proposed project are to
research, develop, and demonstrate experimentally
recycled-energy logic circuits operating reliably
above 500 MHz while dissipating one tenth of the
power of existing circuits.
A 32-channel correlator chip will be fabricated in
Phase I with a 0.5 um process to determine the
feasibility of operating reliably at 500 MHz with 10
mW power dissipation per frequency channel. The
Phase II effort will demonstrate an ultra-low power
256-channel correlator chip fabricated on a 0.35 um
CMOS process and dissipating only 1 mW per
frequency channel at 500 MHz. To achieve the
stated objectives, the following synergistic
combination of concepts will be employed: (a)
recycled-energy logic circuits operating with
alternating current, and (b) resonant power
distribution network implemented with artificial
transmission lines.
The expected benefits of the proposed project
consist of the development of recycled-energy
digital circuits which will enable the implementation
of ultra-low power, real-time digital signal
processing integrated systems for spaceborne and
commercial applications.
Potential Commercial Applications (Limit 200 words)
Ultra-low power digital signal processing integrated
systems implemented with the proposed
recycled-energy logic circuits operating at clock
frequencies above 500 MHz will be used by
commercial firms and research organizations in
applications such as digital cellular telephones,
wireless area networks, global positioning
navigation receivers, and satellite modems. The
256-channel digital correlator chip with a bandwidth
of 500 MHz and 1 mW power consumption per
channel, will be the building block of spectrometers
for radio-astronomy observations and for passive
microwave remote sensing of meteorological,
hydrological, and oceanographic applications.

Technical Abstract (Limit 200 words)
The proposed SBIR effort is aimed at developing
on-board maintenance methods, techniques and a
design-development working environment for
affordable, evolvable and dependable spaceborne
systems. In particular, we are motivated to develop
an on-board maintenance methodology that
minimizes the adverse effects from software

traditional approaches to fault-tolerant spaceborne
computing systems that rely on extensive

the proposed methodology stresses 1) utilization of
the inherent, non-dedicated resource redundancy,
and 2) adaptation and integration of state-of-the-art
techniques across the areas of fault tolerance,
real-time systems and distributed computing. These
emphases will enable us to simultaneously achieve
the low power, low cost, high reliability and high
performance goals for NASA's new-generation
spaceborne systems.
Potential Commercial Applications (Limit 200 words)
The research results will benefit a wide variety of
commercial application domains (in addition to
NASA spaceborne systems). In particular, 1) the
guarded software upgrading techniques will be
useful for many other applications which are subject
to frequent software upgrading and require high
availability and/or safety, such as transportation
systems, airline reservation systems, telephone
systems and medical systems, and 2) the ideas and
methods of utilizing inherent, non-dedicated
resource redundancies and integrated use of fault
tolerance, real-time, and distributed computing
techniques will promote and accelerate the

techniques from research domain to real

Plas-Pak Microelectronics Packaging
for Space
Technical Abstract (Limit 200 words)
This project is to develop for space use a packaging
technology featuring: low cost, improved
hermeticity and radiation shields for PEMs (plastic
encapsulated microcircuits). PEMs are high volume
products, but space use is inherently low volume.
This proposal describes the most cost effective
approach to retro-fitting PEM's for space use. The
technique involves attaching high Z metal shields to
both top and bottom surfaces of PEMs in a manner
which also reduces moisture absorption (on approx.
70% of the surface area), and maintains the
original component footprint. Depending on orbit
and use, these shields should provide a factor of 10
to 300 times total dose enhancement to the PEM.
As commercial PEM's get thinner and smaller, all
other known techniques such as spot shielding,
removal of plastic & insertion of shields, further
encapsulation, etc., all suffer serious drawbacks
ranging from: little to no improvement in
hermeticity; potential impact on device reliability;
shielding only one side of the device; loss of fit
interchangability; inadequate shield thickness; and
considerable re-work costs. The proposed
Plas-Pak packaging concept we believe will
overcome all of these side-effects at the lowest
possible total cost.
Potential Commercial Applications (Limit 200 words)
Since a lot of cutting edge technology microcircuits
are not available in die form, this technology would
vastly expand the number of microcircuits available
to meet natural space radiation environments for
military, NASA, and commercial space programs at
very low cost.

systems applications will include acceleration
measurements for IMU's, structural analyses,
microgravity science, in-space propulsion and
related inertial sensing functions to significantly
reduce the spacecraft's power, mass, volume and
cost requirements via MEMS and microsystem
utilization.

The system can also be utilized in seismometry for
commercial oil exploration.

from radiation complex subassemblies of sensitive
electronics, but as an integrated structure, without
parasitic cables/connectors, and with multifunctional
components. Implementation of this concept
requires new materials which provide greater
functionality per unit mass and more versatility
than currently employed. Furthermore, the new
materials must also be cost effective; i.e., greater
functionality per unit dollar. In Phase I, we will
develop design concepts for new composite
materials concepts, fabricate samples, perform
charged particle attenuation and mechanical
property testing, and recommend promising
concepts for optimization in Phase II. Our materials
development plan will lead to flight demonstration
hardware at the end of Phase II. We will build upon
our USAF Phillips/Wright Laboratories work on
light-weight radiation shielding, TRW will leverage
off their work for NASA Langley on advanced
space structures and provide electronics integration
expertise, with Textron providing expertise in
manufacturing of integrated composites.
Potential Commercial Applications (Limit 200 words)
The technology of multifunctional composite
materials has wide ranging applications to
spacecraft structures and electronic systems
throughout the industry, for both military and
commercial satellites. The benefits of reduced mass
and lower manufacturing costs for the same or
greater functionality should be particularly useful to
the communications satellite business. The
radiation shielding properties of proposed materials
are potentially useful in instrumentation used in
monitoring hazardous nuclear waste sites and in
radiation therapy hardware.

Project Title: Highly Integrated Radiation Shielding Structures for
Aerospace Systems
Technical Abstract (Limit 200 words)
The NASA Space Exploration Initiative (SEI) Program has recognized the threat of a variety of radiation ranging from low energy UV to cosmic rays, neutron radiation, etc. to the space-based systems. Amongst these, neutron radiation is one of the most damaging to sensitive instrumentation and humans. Various shielding methods have been considered for neutron shielding. These shields tend to add parasitic weight and volume to the space based systems. Hence, it would be highly desirable to develop a neutron shield that is multifunctional, either as a structural member or as a heat sink to further increase the overall usefulness of the shield. LoTEC, Inc. proposes to develop a multifunctional microcomposite materials system that is well suited for neutron shielding as well as other critical applications related to space based systems. Such a multifunctional material is expected to further improve the performance of the space-based systems and allow additional payload on the spacecraft. This multifunctionality is attained through the use of innovative polymers and use of enriched and surface-modified boron.
Potential Commercial Applications (Limit 200 words)
The primary civilian applications include shields for nuclear power plants, shielding for the commercial satellites, and shielding electronic equipment and personnel in the future commercial space activities. The military uses for these shields range from nuclear powered submarines and shielding for weapons program. Successful development of a cost effective multifunctional shields will find applications in the medical industry, especially where neutron radiation therapy is used.

Project Title:
Desensitized Optimal Guidance of
Uncertain Systems
Technical Abstract (Limit 200 words)
It is proposed to develop a trajectory optimization
software package that enables the simultaneous
optimization of a user-specified cost criterion along
with reducing the sensitivity of the resulting
trajectory with respect to modeling errors, external
perturbations, etc. Such insensitivity is a highly
desirable feature for any MDO component or
systems analysis tool. In addition, trajectory
optimization with reduced sensitivity has been long
sought as a stand-alone tool. Specifically, the
project objectives are to extend the existing theory,
which has recently been introduced by the PI, to
enable the treatment of problems with free final
time, control constraints, and state constraints, and
to test ideas for a fast and efficient numerical
implementation scheme. It is proposed to achieve
these objectives through analytical derivations and
through numerical testing and verification. It is
anticipated that the theoretical ground work will be
developed for an easy-to-use desensitized optimal
control software package. The expected NASA
applications include practically all areas of today's
optimal control applications, such as launch vehicle
guidance, aeroassisted orbital transfers,
interplanetary space flight, rocket landing, etc.
Potential Commercial Applications (Limit 200 words)
Direct commercial markets for the software
developed in Phase II: All industries requiring
optimal control of uncertain or externally perturbed
systems, such as aircraft/spacecraft/rocket/missile
guidance, robotics, chemical process control and
optimization, industrial and civil engineering design,
and the control of economic systems. Indirect
commercial potential: Customization of the Phase II
software, consulting, and application of the
developed technology to non-linear robustness
problems.

Project Title: Autonomous Health-Monitoring and Fault Tolerant Control for Formation Flying Spacecraft using InteractingMultiple Model Estimation and Nonlinear Model Predictive Control
Technical Abstract (Limit 200 words)
NASA's New Millennium Program (NMP) includes missions incorporating miniature spacecraft flying in tightly controlled (position and attitude) Autonomous Formation Flying (AFF) configurations. Unprecedented levels for autonomy, reliability, low bandwidth communication with their base stations, and robustness of AFF control to sensor/actuator/spacecraft failures are critical to mission success. We propose an Autonomous Failure Detection, Identification and Reconfiguration approach for AFF spacecraft, using the combined techniques of Interacting Multiple Model-Extended Kalman Filters (IMM-EKF) and Adaptive Nonlinear Model Predictive Control (NMPC), developed recently by Scientific Systems for single spacecraft. The proposed Fault-Tolerant Autonomous Control Architecture (FT-ACA) will compensate (detect and autonomously reconfigure the control law) for sudden or gradual failures of various sensors, including inter-spacecraft communications, GPS based AFF GNC sensors optical range sensors, SRU/IRU sensors, or in the worse case a complete unit spacecraft failure. Phase I tasks include the development and application of IMM-EKF and NMPC techniques for specific AFF mission scenarios, evaluation of its performance on a representative mission (such as the optical interferometer), and a conceptual design for an overall FT-ACA which will improve reliability of AFF mission success.
Prof. John Wen from Rensselaer Polytechnic Institute will serve as a consultant on this project. Dr. H. Rauch from Lockheed Martin Advanced Technology Center will provide technical and commercialization support.
Potential Commercial Applications (Limit 200 words)
In the commercial sector projects involving miniature spacecraft formations are fast growing. Already, upcoming programs such as IRIDIUM or Teledesic propose similar multiple satellite constellations. The proposed approach for failure detection and control reconfiguration for spacecraft formations has a great commercial potential in this fairly untapped market. The development of the Fault Tolerant Autonomous Control Architecture as proposed in this SBIR effort also opens a range of applications in aircraft and process control industry. Scientific Systems has already established relationships with a number of commercial partners including Bell Helicopter, Lockheed-Martin and Orbital Space Sciences to discuss applications of such a control architecture system to meet their specific needs.

Project Title: Very High Performance RISC/DSP
Technical Abstract (Limit 200 words)
The PMEL (Processor Memory Element)architecture is a means of using internal parallelism in a chip design to perform DSP or RISC processing. The internal processing in the chip under a single program counter permits an 800% increase in performance. Although a VLIW instruction stream is used, this is NOT a classical VLIW design. The unique PMEL structure using on chip "intelligent memory" eliminates a von Neumann bottleneck in the data store cycle. This includes the path from the ALU data execution to the storage in register memory. This is accomplished by an efficient bussing scheme which permits a one cycle fetch, execute, and save. If a 250 MHZ clock is used to process instructions, the architecture outputs operations at 2000 MIPS, so that there is no additional power dissipation penalty associated with the significant performance increase. The increase in performance without severe power penalties offers NASA a computational device with potential for a variety of agency needs.
Potential Commercial Applications (Limit 200 words)
The commercial potential for the PMEL is quite significant because of the current demand for improved performance for RISC and DSP processors. A specific approach is to obtain a licenseing agreement with a DSP or RISC computer manufacturer, and clone that design using the internal structure of the PMEL, so that the PMEL functions as a "workalike".

Project Title: A Solar-Blind Silicon Carbide Ultraviolet Avalanche
Photodetector
Technical Abstract (Limit 200 words)
We propose to design and deliver a high performance avalanche photodiode (APD) for 0.15 to 0.35 µm ultra-violet (UV) applications. The innovation is the use of high- temperature and radiation-tolerant, wide-bandgap silicon carbide (SiC) (4H and 6H) combined with a novel co-implantation approach which makes it possible to create p+-SiC guard rings. A unique feature of 6H and 4H-SiC is the very high k ratio (over 60) of hole/electron ionization coefficients which provides the possibility of fabricating very low noise APDs while maintaining high speed due to the high saturation velocity of both electrons and holes in SiC. In Phase I, we will demonstrate the feasibility of a p+/n-/n+ SiC APD using p-type guard rings created by C and Al co-implantation, determine the avalanche gain, and measure the k ratio for the CVD-grown 6H-SiC. We will also create a Monte Carlo model for ionization coefficient calculations and integrate it with the Sylvaco CAD tool to model the SiC APD for Phase II APD optimization. In Phase II, we would model the performance of 6H and 4H-SiC APDs and, based on Phase I results, fabricate and optimize a reliable planar SiC APD covering the spectral range of 0.15 to 0.35 µm. Prof. Jian Zhao of Rutgers University will consult.
Potential Commercial Applications (Limit 200 words)
A high performance visible-blind UV photodetector capable of high temperature and high radiation tolerance for spectroscopic imaging, UV radiometry, flame sensing/fire control, and missile guidance systems. Currently, the only devices capable of addressing these applications are the bulky photocathodes that are difficult to integrate with control electronics and in general require high operating voltages.

Metalorganic Chemical Vapor
Deposition Grown GaAs Junction
Field-effect Transistors for Low-noise
Deep-cryogenic Readouts
Technical Abstract (Limit 200 words)
Low-noise readout electronics are needed in
cryogenic detection systems for applications
including earth- and space-based observation.
Compared to conventional electronics, Si- and
GaAs-based junction field effect transistors
(JFETs) offer the best low-noise performance. At
extremely low temperatures, GaAs JFETs are
preferred because they offer "hopping" transport
and do not suffer from freezeout problems of Si
JFETs. While several groups have fabricated GaAs
JFETs using MBE, these devices have not
achieved their theoretical performance due to a
variety of reasons. Spire proposes to develop GaAs
JFETs using metalorganic chemical vapor
deposition (MOCVD), since this process provides
material with longer carrier lifetimes and different
characteristic traps and defects than MBE-grown
material, to produce extremely low-noise devices.
In Phase I, Spire will demonstrate proof-of-concept
by depositing and fabricating large-gate JFETs and
identify optimum MOCVD procedures for the best
devices. In Phase II, the development will be
extended to develop devices and integrated circuits
for specific applications.
Potential Commercial Applications (Limit 200 words)
Low-noise JFETs will be important components for
enabling low-noise readout electronics for space-
and earth-based telescopes. In addition, they will
find applications in sensing and detection of
extremely low level signals.

High Resolution Room Temperature
Gamma Ray Detectors
Technical Abstract (Limit 200 words)
We propose an innovative structure that enables
the use of currently available low quality materials
to achieve high quality operation at elevated
temperatures. We anticipate 2.5% energy
resolution at 60 keV for room temperature
detectors in Phase I, and better performance after
Phase II development ( 1% energy resolution). In
contrast to standard detector structures, this
structure is extendable to higher sensitivities
without degrading energy resolution, in contrast to
standard solid state detectors. This structure can be
implemented in any material system, so
improvements in material quality will lead to further
improvements in the performance of this structure.
In Phase I we expect to build a monolithic detector
capable of room temperature sensitivity equivalent
to that of 1 - 2 cm thick high purity Ge. Phase II will
be directed at achieving high quality two
dimensional imaging while retaining the high
sensitivity, high energy resolution room
temperature operation provided by this innovative
structure.
Potential Commercial Applications (Limit 200 words)
The areas of projected high impact for improved,
room temperature gamma ray detectors include
airport security systems, oil well data logging
sensors, and non-destructive evaluation (NDE) of
critical structures. It also provides an additional
approach to the crucial balance in sensor design
between resolution and sensitivity for space-borne
applications without the need for costly (and
power-hungry) cryogenics. Gamma ray detectors
are expected to become increasingly important to
the world's technological needs, including the
extension to two-dimensional imaging applications
for NDE and medical imaging.

New Ultra-Shallow Junction Technology
and Improved Oxides for Silicon
Technical Abstract (Limit 200 words)
The performance of silicon radiation detectors is
strongly dependant on having a shallow rectifying
junction which is characterized by a small dead laer,
a high barrier height, high break down voltage and
low leakage current. This project will develop a
radiacal new approach to diffused junction
technology which shows promise for fabricating
ultra-shallow junctions with excellent electrical
properties. It will also develop this same technology
for producing uniform, high sheet resistance layers
for fabrication of on-wafer, high-value resistors for
segmented detector applications. In addition, we
propose to use nonoengineering surface processes
to develop a new technology for thermal oxide
passivation. We expect these new passivations to
have superior edge breakdown characteristics and
low leakage currents so that deep depletion
detectors can be fabricated without the need for
complicated guard ring structures. We also expect
these new oxides to have superior resistance to
ionizing radiation damage.
Potential Commercial Applications (Limit 200 words)
The technologies which we propose to develop are
fundamental to all classes of Si radiation sensors
and if successful should have a major impact on the
performance and fabrication cost of a broad range
of radiation detector products. Additionally, the
ultra-shallow junction technology may make a major
contribution to the general field of sub-micron
device fabrication.

Polyimide X-ray Filter Substrates
Optimized for Strength at Cryogenic
Temperatures
Technical Abstract (Limit 200 words)
New generation x-ray instruments for spacecraft
have very specialized requirements, notably
operation at cryogenic temperatures. The proposed
innovation is to produce polyimide films suitable for
use as x-ray filter substrates specifically optimized
for cryogenic applications. Earlier work by the
offeror showed that polyimide film strength (at
room temperature) was affected by the post-cast
processing or cure cycle. It is proposed to process
polyimide films using different cure cycles, and to
perform burst pressure (tensile strength) analyses
at 77, 15, and 4 Kelvin (K) on these films.
Cryogenic burst data will be compared to existing
burst data on Luxel-manufactured polyimide
developed for x-ray applications. Cryogenic burst
test data is presently not available for submicron
polyimide films. It is anticipated that Phase I will
demonstrate increased strength at cryogenic
temperatures for films processed using altered cure
cycles and that Phase II will permit further
optimization of films and processing parameters for
operation in the temperature range of 77 K to 4 K.
Potential Commercial Applications (Limit 200 words)
Targets (with thin film windows) utilized in Inertial
Confinement Fusion to be used at the National
Ignition Facility will be deployed at cryogenic
temperatures. Researchers in light element
analysis and kinetic studies could also utilize such
polyimide substrates as windows in their detectors.
Capacitive transducers could utilize polyimide as
dielectric membranes with metalized polyimides
serving as sonic energy emitters and receivers.
Dielectric multilayer stacks may be used in
microwave applications. Improved strength would
be useful in separation membranes and biosensor
membranes.

Technical Abstract (Limit 200 words)
High density passive component arrays are

and foot print size of reliable arrays. NRC proposes
a technology that can overcome this technology

the proposed technology, develop prototypes and
field test the arrays with lead customers. Phase III

Arrays manufactured from nanostructured

Imaging X-ray Spectrometer using
Tunnel Junctions on Tantalum Crystals
Technical Abstract (Limit 200 words)
We propose to radically extend the capabilities of
cryogenic X-ray detectors by building an innovative
imaging array with good quantum efficiency for
12keV X-rays and good energy resolution while
using conventional, room temperature,
preamplifiers. The thin-film superconducting tunnel
junction (STJ) X-ray detectors we have produced to
date, while setting the standard for such devices in
energy resolution, area, and count-rate capability,
still have been inefficient for high energy X-rays
and fairly small in size. In the work proposed here,
we will build an imaging array of STJ devices on the
surface of a large, superconductive, crystalline
absorber. The large, single absorber with STJ
detectors will provide position information so that a
large area can be imaged with a relatively small
number of detectors and readout electronics. While
not providing the absolute utmost in resolution, the
resulting spectrometer system will combine imaging
capability, large area, high efficiency, and good
resolution with the ease of use allowed by a relative
small number of conventional, room temperature
FET amplifiers.
Potential Commercial Applications (Limit 200 words)
The large area, high count-rate capability, high
energy resolution, and ease of use of the proposed
detectors will make them uniquely suited for
commercial application in X-ray microanalysis in
SEMs and for X-ray fluoresence. In these
applications, these devices will yield about an order
of magnitude improvement in resolution over
conventional detectors, easily allowing the
resolution of X-ray lines of light elements, while
providing performance that is otherwise
comparable.

Efficient Backward Wave Oscillators
for Millimeter and Submillimeter Wave
Applications
Technical Abstract (Limit 200 words)
This research will result in development of
advanced millimeter and submillimeter wave
Backward Wave Oscillators (BWOs). Successful
development will result in devices requiring
significantly less input power, require less cooling,
have reduced weight, and have improved mode
purity. Calabazas Creek Research, Inc. is
proposing to develop the first BWOs with a
depressed collector, spent-beam, energy recovery
system that will significantly reduce the prime
power requirement and allow air cooling instead of
water cooling. An additional goal will be to develop
mode converters between the slow wave structure
and the overmoded output to allow for single mode
operation. Finally, advanced permanent magnet
technology will be applied to reduce magnet and
system weight.
BWO sources are presently used for ground based
atmospheric sensing of trace chemicals, testing of
solid state sensors, and basic spectroscopy
research. This innovatve development will allow
these devices to be used for airbourne or space
atmospheric sensing missions, as well as reduce the
cost and complexity of BWO sources, making their
unique tunability and output power capability more
accessible to both private and government
laboratories.
Potential Commercial Applications (Limit 200 words)
The proposed program will result in the
development of efficient, lighter-weight, millimeter
and submillimeter BWOs applicable to the following
commercial applications:
* Laboratory and remote spectroscopy, material
analysis, aquametry, and medical research,
* Millimeter and submillimeter wave sources
available for airbourne and space missions for
molecular line astronomy and atmospheric
environmental sensing,
* Heterodyne sources for the new, proposed, large

Ultralightweight, Compact, Thermally
Stable, SiC, Snap-Together Microwave
Instrument
Technical Abstract (Limit 200 words)
A need exists to reduce the weight, size, power
requirements, and cost associated with next
generation, space-based microwave sensors. Trad-
itional optical materials, such as aluminum or glass,
are severely limited in their capability to be
lightweighted. More exotic mater- ials, i.e.
Beryllium, can be used to produce very lightweight
sensor structures but at a very high cost. SSG
proposes the application of Reaction Bonded
(RBO) Silicon Carbide (SiC), and an innovative
Con- tinuous Fiber Reinforced Ceramic (CFRC)
SiC composite as ultralight- weight, thermally
stable, low-cost materials for these applications.
The two materials will be used in an innovative
snap-together design to facilitate
assembly/alignment, and offer significant cost
savings. The Microwave Instrument for the
Rosetta Orbiter (MIRO) currently uses aluminum
as a baseline sensor material; the use of the SiC
materials would reduce the weight associated with
the MIRO instrument by a factor of 2x-4x. The two
proposed forms of SiC have the same coeff- icient
of thermal expansion and excellent thermal
stability. These properties will support a passively
athermalized instrument concept able to withstand
severe thermal environments ranging from
cryogenic to 800°C (suitable for missions to Mars
or Venus). During the Phase I effort SSG will
demonstrate the feasibility of the material based on
the MIRO requirements. Analytical models will be
used to generate a conceptual model of the off-axis
Cassegrain reflector system and project the weight
savings obtained with the CFRC SiC material.
Empirical testing of a smaller MIRO mock-up, and
a number of smaller test coupons, will be used to
demonstrate thermal stability, surface finish and
surface figure capabilities, mechanical strength, and
microwave reflectivity. The results of Phase I will
provide a basis for fabricating a full-scale MIRO
prototype during Phase II.
Potential Commercial Applications (Limit 200 words)
The lightweight and low-cost nature of RBO SiC

SiC materials to Phase III applications which
require visible quality optical performance
(DS1/MICAS, EO1/Landimager), the proposed
SBIR will extend the use of these materials to a

Project Title:
Low-cost pulse tube oxygen liquefier
Technical Abstract (Limit 200 words)
Mesoscopic Devices proposes to develop a
low-cost, highly compact and efficient oxygen
liquefier using a pulse tube cryocooler. This
liquefier will be more compact and will have lower
input power than conventional designs due to its use
of a unique inertance tube geometry, a highly
efficient moving-magnet linear compressor and an
innovative and highly effective oxygen condenser
geometry that allows the oxygen to exit very close
to the cold tip temperature. We expect these
innovations to lead to a reduction in required input
power of more than 20% over state-of-the-art
double-inlet pulse tube designs. The core
technology for the pulse tube liquefier is highly
scaleable and can be adapted to machines with
cooling powers from a few watts to several hundred
watts. Our proposed design is an extension of
existing technology originally developed for
terrestrial telecommunications applications, and so
is both low-cost and extremely reliable. In Phase I,
Mesoscopic Devices will demonstrate through a
combination of analysis, design and prototype
fabrication the potential of the pulse tube
cryocooler.
Potential Commercial Applications (Limit 200 words)
The low-cost oxygen liquefier will find applications
in both DoD and commercial markets. Oxygen
liquefiers are used in mobile field hospitals by both
the military and by agencies such as the Red Cross.
Aircraft crews can use oxygen generation systems,
avoiding accidents associated with filling LOX
tanks. Our primary commercial market will be for
oxygen liqefiers for use in the home medical
market. Over 200,000 home medical oxygen
delivery systems are installed every year. Our
technology will increase mobility and quality of life
for these people. The basic advances in pulse tube
cryocooler technology developed in this project will
also find use in superconducting circuits,
telecommunications, and medical applications
(SQUIDs).

High Efficiency 10K Pulse Tube Cooler
Technical Abstract (Limit 200 words)
The pulse tube cooler (PTC) has become the cooler
of choice for space missions for its inherent
reliability and low vibration. To advance this
technology Atlas Scientific proposes to improve its
efficiency and cooling power employing innovative
high heat capacity materials in the regenerator. We
propose to employ a newly developed material for
which the heat capacity exceeds that of all other
known materials in the temperature regime from
20K up to 85K. This feature will enhance both the
cooler's low temperature cooling capacity and lower
its no-load temperature. We propose to build a
single stage cooler in Phase I as proof of concept.
In Phase II a two stage cooler will be built achieving
high cooling power at the target temperature of
10K, the temperature required to liquefy hydrogen.
The superior properties of the materials employed
in the proposed cooler will enable sizable
improvements in the efficiency and cooling power of
the PTC making it more suitable for space
missions. The proposed advancement is particularly
relevant for costly missions such as sample return
from Mars. Commercially, the PTC is likely to
replace the widely used but less efficient G-M
coolers in such applications as MRI, cryopumps
and superconductors.
Potential Commercial Applications (Limit 200 words)
The proposed pulse tube cooler can be employed in
a wide variety of commercial applications. The
following lists potential applications for this
cooler:
- Cryopumps for semiconductor manufacturing (T ~
10 - 20 K)
- Cryogenic catheters and cryosurgery
- Superconducting magnets for MRI systems
- Superconducting magnets in maglev trains
- SQUID magnetometers for heart and brain
studies

Project Title:
INTEGRATED CRYOGENIC
HELIUM SYSTEM FOR EXTENDED
DURATION BALLOON FLIGHTS
Technical Abstract (Limit 200 words)
NASA is presently developing an Ultra Long
Duration Ballooning (ULDB) capability. This will
provide low cost, satellite like flight opportunities
for durations of up to 100 days. Innovative
technologies will be required to realize this new
capability. GSSL proposes an Integrated Cryogenic
Helium System (ICHS) for both extending flight
duration and augmenting on-board instrument
cooling. The ICHS consists of a combination liquid
helium and high pressure storage system, balloon
envelope interfaces, and an integrated control
system linked to the balloon control system and
on-board coolers. Major ICHS components are
bundled into a single unit that can be safely
jettisoned. Additionally, the lift surge capability
provided by the ICHS will allow trajectory
modification through altitude change. Flying
multiple orbits of the earth will create significant
political, logistical, and safety issues. Trajectory
modification will be critical for avoiding undesirable
flight paths and allowing successful recoveries. The
Phase I program will define strawman ULDB
payload requirements, identify ICHS hardware
requirements, and provide detailed design
specifications. Phase I results will provide the
necessary basis for the detailed design and
fabrication of a prototype ICHS in Phase II. The
interim Phase I results will be significant to NASA's
continuing ULDB development.
Potential Commercial Applications (Limit 200 words)
Scientific ballooning is a small niche market that is
dominated by NASA's balloon program. The
Integrated Cryogenic Helium System is designed to
be a powerful tool in both vehicle design and
mission planning. NASA has immediate need for
such a system, especially in the current ULDB
development program. Concurrently, GSSL is
developing a small commercial superpressure
program using its WindStar technology that will
also benefit from having an ICHS. The modular
design and flexible control system allows the ICHS
system to be applied to a wide range of balloon
sizes and mission requirements. While the ICHS is
specifically designed for extended duration balloon
flights, the basic technology has applications to any
system that requires intermittent cooling boosts.
These might include solar telescopes, laser based
instrumentation, or motor drive systems. Any
cryogen could be used, including liquid helium,
nitrogen, or others. The modular design approach of
the ICHS along with its LabVIEW interface brings
a high level of flexibility to any application, allowing
easy customization and modifica-tions for any
specific mission or instrument.

A Lightweight, Low Cost, Long
Lifetime Cryostat and Magnetic
Refrigerator
Technical Abstract (Limit 200 words)
We propose to build a lightweight, low cost, long
lifetime cryostat and magnetic refrigerator for
cooling detectors to 0.1 K. The passively cooled
cryostat will be compact, highly reliable and will
have a lifetime greater than 100 days. The passive
cooling bypasses the use of active cryocoolers and
their associated vibration, reliability, and power
dissipation problems. The magnetic refrigerator will
have lower power consumption (0.2 W nominal), and
it will be remotely recyclable. This system makes
use of several innovative design features that
include: a two stage adiabatic demagnetization
refrigerator (ADR) that operates from a 4 K liquid
helium stage rather than a 1.5 K pumped helium
stage, a 17 K solid neon (SNe) reservoir that is
used as the secondary coolant, and very efficient
heat exchangers and two vapor cooled shields. In
Phase I we will build a prototype LHe-SNe ADR
that has a lifetime of at least 10 days, and in Phase
II we will build a LHe-SNe ADR with a lifetime of
at least 100 days that can be used in NASA's 100
Day Ultra Long Duration Balloon program. These
unique design features are readily transferable to
cryostats used in more conventional applications.
Potential Commercial Applications (Limit 200 words)
A long lifetime cryostat and magnetic refrigerator
can be used for cooling bolometers made from
superconducting tunnel junctions and transition
edge sensor microcalorimeters, for detecting
electromagnetic radiation in the millimeter, far IR
and X-ray regions. In addition to their usefulness in
astrophysical measurements, they can also be used
in conjunction with scanning electron microscopes
for precision surface characterization for
microanalysis of systems used in the semiconductor
industry. They can also be used as particle
detectors and combined with mass spectrometers
for applications in heavy molecule mass
spectroscopy for studying biological samples and
DNA sequencing. A low loss, vibration free
cryogenic cooling system would be a welcome
addition to these and other related applications,
especially if it also offers long uninterrupted
operation that would only require servicing three
times a year.

Project Title: Microhotplate Based, Palladium-Coated Metal-Hydride Thin Film Hydrogen Sensor arrays
Technical Abstract (Limit 200 words)
NASA currently has an urgent need for miniature, robust chemical sensors for in situ analysis. These sensors must be small in size, have low power consumption, be resistant to contamination, require infrequent calibration, have a large dynamic range, and be able to withstand the high stress environments required by NASA. We propose to use micro-machined structures known as micro-hotplates coupled with newly developed palladium-coated metal-hydride thin films to make hydrogen specific gas sensors. Palladium-coated metal-hydride films have only recently been fabricated and have not yet been used as the active layer on micro-hotplate structures. The have, however, demonstrated a remarkable degree of selectivity for the detection of hydrogen on bulk substrates. The micro-hotplate structure offers the unique advantages of rapid, precise temperature control and the potential for array fabrication. These sensors will have an active element size of ~100 mm and predicted power consumption of less than 60 mW. In phase I, Pd coated thin films of yttrium, and yttrium doped with magnesium, be deposited on micro-hotplate structures and their sensitivity to hydrogen will be tested. In the Phase II program, the sensing films will be optimized with respect to sensitivity, selectivity, and manufacturability, and robust calibrated testing algorithms developed.
Potential Commercial Applications (Limit 200 words)
The sensor market worldwide is estimated at $8 billion with a 7% annual growth rate. These sensors will enjoy a significant, unfilled market niche. In addition to addressing safety concerns in space and military applications, these sensors will also find use in the broad $ 200 million market of merchant hydrogen.

Project Title: Microminiature Wireless Instrumentation System (MicroWIS)
Technical Abstract (Limit 200 words)
NASA seeks advanced sensor systems to improve the effectiveness of structural and environmental testing by simplifying and minimizing sensor installation costs while improving the quality of measurements. The system proposed herein fulfills this requirement because of its small size and ability to be installed virtually anywhere with no support costs such as wiring for data or power. This integrated communications network, termed the "Microminiature Wireless Instrumentation System," (MicroWIS) can support spatially displaced sensory locations and accumulate the data into analysis centers where computers and/or human experts can use the data to analyze or manage complex processes. The MicroWIS system would be interfaced with and controlled by a wireless network currently under development by Invocon for the ISS. Data and command flow would be handled automatically by the wireless network of relaying nodes, making the system appear to the user as if the sensors are functionally "hard-wired" as with current systems. MicroWIS will be developed as a modular system, enabling easy customization to meet a wide variety of distributed data acquisition requirements. Initially, primary batteries or solar power will satisfy the power requirements with future development phases exploring other options. Flexible, low-power analog signal conditioning and acquisition electronics will be integrated with the transceiver and power systems to form a complete data acquisition system in a 5 cubic centimeter package.
Potential Commercial Applications (Limit 200 words)
Communications technology would be applied to Condition Based Monitoring systems for structure, machinery, systems, and geophysical applications. Further, the technique will be used in data acquisition systems where data points are distributed in space and not easily supplied with wired signal paths or prime power.

Penning Ionization Electron
Spectroscopy for Gas Chromatography
and Trace Analysis
Technical Abstract (Limit 200 words)
A new analytical technique is proposed which will
provide direct molecular identification of gas
mixture components. The method is based on a
fundamental physical property of atoms and
molecules, the ionization potential, and relies on the
measurement of the energy of electrons liberated
by Penning Ionization in a gas discharge. Penning
Ionization is the same process used in MID
detectors and the advanced Helium IMS developed
by PCP Inc. and Ames Research Center. However,
the proposed approach rather than simply counting
the number of ions or electrons produced by
Penning Ionization, will measure the energy of the
electrons produced. Since the ionization energy is
specific to each molecular species, the resultant
data can be used to directly identify each
component. No optics or ultrahigh vacuum are
required. The technical simplicity of this method of
this method and its capability to directly identify
most known species with high sensitivity make it an
ideal candidate for analytical flight instrumentation.
The principal result of the proposed effort will be
the development of a compact, robust and simple
analytical device suitable for application as an
advanced detector for Gas Chromatography and as
a portable stand-alone analyzer.
Potential Commercial Applications (Limit 200 words)
The proposed GC detector will be especially
suitable for High-Speed Gas Chromatography.
These methods require detectors capable of fast
responses, and the reading time of one millisecond
achievable by the proposed detector can be helpful
in this application.
As a portable stand alone gas analyzer the
proposed detector will be suitable and particularly
attractive for a wide range of applications for:
industrial, forensic, military, security, research,
environmental and educational needs. Some
specific applications include: monitoring of the
environment for pure industrial processes, such as
microprocessor manufacturing or plasma
processing; forensics field applications in general
and police work in particular;. landmine detection
and airport security; hazardous waste treatment
and others.

Compact, Low Cost Gas Sensor for
Space Exploration
Technical Abstract (Limit 200 words)
CoreTek, Inc., proposes to develop a highly
compact, innovative gas sensing spectrometer. The
two key innovations in this proposal are: (i)
integrtion of an agile, widely tunable Fabry-Perot
interference filter (500um x 500um x
300um)necessary for wavelength selectivity with (ii)
a proprietary, lightweight, fiber-based wavelength
meter. Due to the compactness of the filter and the
wavelength meter, the proposed spectrometer will
meet the stringent size, weight and power
requirements for NASA's space exploration
programs. Due to the wide (100 nm) and swift (10
nm/usec) tuning capability of the MEM tunable
filter, this spectrometer will be capable of sensing
multiple species of gases rapidly. To demonstrate
feasibility in PhaseI, we propose to devise this
spectrometer for sensing CO2 by performing an IR
absorption spectroscopy.
In PhaseII, we propose to develop a fully packaged,
compact multiple-gas sensor which comprises
tunable, broadband super-luminescent light emitting
diode (SLED) and the fiber-based wavelength
meter. This will provide an additional advantage
towards integrting both the broadband source and
the spectrometer.
Potential Commercial Applications (Limit 200 words)
The proposed program is designed to develop
breakthrough products for unfulfilled market needs
for integrated, compact tunable filter and laser for
environmental monitoring of gasses, aerosol
characteristics, non-intrusive blood oxygen and
sugar level detectition, optical read/write heads in
CDs and wavelength selection and monitoring for

Project Title: Tool Factory for Spacecraft System Components
Technical Abstract (Limit 200 words)
The long-range goal of this proposed effort is to overcome barriers to building and deploying spacecraft real-time embedded systems from verified, reusable software components. The promise of component-based applications is to enable developers to "snap together" new applications by mixing and matching prefabricated software components. However, the lack of a standard real-time distributed object operating system, lack of a standard Computer-Aided Software Environment (CASE) tool notation and lack of a standard CASE tool repository has limited the realization of component software.
Our approach to fulfilling this need is the Tool Factory. The Tool Factory takes advantage of emerging standards such as UML, CORBA, Java and the Internet. This work will build on the recently available CORBA real-time operating system services. Additionally, Unified Modeling Language (UML) is fast becoming the industry standard for object-oriented analysis and design notation for object-based systems. The key technical innovation of the Tool Factory is the ability to assemble and test new system configurations as well as assemble new tools on demand from existing tools and architecture design repositories.. Once the Tool Factory is in-place, spacecraft mission specific systems can be assembled from tools, system components and design architecture repositories located anywhere on the Internet.
Potential Commercial Applications (Limit 200 words)
Reusable tool and system components will result in significant reductions in the lifecycle cost of distributed embedded real-time systems. Application market niches include communication network management, patient bed-side monitoring and management, weapons system command and control, unmanned vehicle control, and on-board avionics systems

An Onboard FDIR System for
Autonomous Spacecraft
Technical Abstract (Limit 200 words)
The goal of this work is to develop a real-time
diagnostic system that can meet the long-range
autonomy requirements of NASA spacecraft. In an
earlier effort with NASA-Ames and Boeing-North
American, we had developed and demonstrated
TEAMS-RT, a software tool for the diagnosis of
multiple faults in a system with up to 1000 sensors
and 1000 failure aspects in about 0.1 second. The
proposed effort will enhance TEAMS-RT by: (i)
developing an inference engine for real-time
monitoring in the presence of imperfect tests and
temporary failures; and (ii) adding the capability to
perform additional drill-down tests, results of which
will enable quick and accurate fault isolation. In
Phase II, we will add modules for prognostics,
feature extraction, sensor validation, and
reconfiguration to the core TEAMS-RT product.
The resultant diagnostic system will be efficient,
responsive and accurate, facilitating prompt
reconfigurations in the event of failures. The
proposed onboard diagnosis and prognosis solution
will reduce troubleshooting time in the ground
station, facilitate condition-based maintenance, and
reduce the likelihood of loss of mission due to
sudden failures. The resulting solution will be
integrated with the software monitoring and
troubleshooting solution, being proposed separately
(topic 24.03), to provide a comprehensive solution
for onboard Fault Detection, Isolation and
Reconfiguration (FDIR).
Potential Commercial Applications (Limit 200 words)
The proposed technology can be applied to several
applications that require automated monitoring and
diagnosis, including
1. Quality control and real-time monitoring of
manufacturing processes
2. Automotive diagnosis
3. Commercial aircraft diagnosis and prognosis
4. Patient health monitoring in Emergency Rooms
and Intensive Care Units
5. Monitoring of hardware and software systems in
safety critical systems, such as the various Wind
Tunnel systems at NASA.
6. Performance monitoring of computer
communication networks.

A Distributed Environment for Onboard
Planning and Scheduling
Technical Abstract (Limit 200 words)
Spacecraft autonomy has the potential for effecting
significant cost reductions in mission operation by
eliminating the need for dedicated ground staff. In
an autonomous operating mode, operators will
communicate only high-level goals and deadlines
directly to the spacecraft. The spacecraft will then
perform its own planning and scheduling,
decomposing the schedules into a set of primitive
actions by optimizing onboard resources, and then
execute autonomously. In this proposal, we present
a distributed approach to address this problem,
where a set of agents representing onboard
subsystems communicate and cooperate to achieve
goals. This kind of distributed planning and
scheduling emphasizes a decentralized organization,
where plans are generated and executed
co-operatively and concurrently by the subsystem
agents, taking into account system flight rules and
resource constraints. We address specifically the
resource optimization problem by its explicit
representation within the problem domain. The
reasoning performed by an agent will be based on a
constraint propagation paradigm, using hierarchical
knowledge structures popular in the AI planning
community. We are specifically targeting our effort
to enhance the existing planning and scheduling
capability of JPL's New Millennium Remote Agent
(NMRA) architecture.
Potential Commercial Applications (Limit 200 words)
There are potential commercial applications for
three important aspects of the technology in the
proposed distributed environment: 1) intelligent
agents and multi-agent systems; 2) planning and
scheduling; and 3) resource optimizations.
Intelligent agent technology is directly applicable to
commercial satellite systems, telecommunications
satellites and remote sensing space systems.
Applications of multi-agent technology exist in
airport control towers, electronic stock exchanges,
and transportation systems. Planning, scheduling
and resource optimization technology is directly
applicable to transportation and inventory control.

Technical Abstract (Limit 200 words)
We propose to develop a novel holographic volume memory that has ultra high data storage capacity and throughput (in excess of 1012 bits storage and 1 bit/second transfer). The proposed method is based on the revolutionary concept of Speckle Wave Multiplexing. The device has a compact architecture similar to conventional optical CD ROMs. We employ a spatially-encoded reference wave that permits recall of stored information by spatially-shifting the mutual position of the encoded reconstruction beam and the storage medium. Entire data pages (in excess of 1 Mbit) can be recalled in parallel. Phase I research will extend existing analytic models of the spatially-multiplexed 3D holographic memory to optimize system design, perform experimental tests to validate the model, demonstrate operation of a scaled memory device and estimate performance of a full scale system. The fully developed system will significantly extend the archival and retrieval data capacity of NASA in terrestrial and spaced based information systems.
Potential Commercial Applications (Limit 200 words)
The proposed holographic volume memory has tremendous commercial potential in virtually every type of computer system for both the federal government and the private sector. In addition, the proposed system is particularly useful for security applications such as banking or proprietary data transfer where access to information needs to be restricted.

Research objectives include the reconstruction of a sample flood plain using GIS and 3D modeling tools, examination of wavelet algorithms to represent dynamic changes to the terrain surface, evaluation of DoD modeling and simulation systems and standards for applicability to flood hazard modeling, and the evaluation of emergency management planning, hazard warning, response, and mitigation processes to determine the suitability of advanced distributed simulation technologies to support these efforts. LNK has acquired the services of Urban Regional Research, a leading firm in the area of hazard mitigation and urban planning to assist it in evaluating issues specific to the problem domain.
Potential Commercial Applications (Limit 200 words)
This research will facilitate the development of commercially available simulation and data visualization tools which:
1. Enhance response capabilities to natural disasters and
2. Improve capabilities to mitigate the effects of natural disasters and reduce losses from such events.
In order to maximize response capabilities and minimize losses, simulation and data visualization tools must facilitate rapid decision making in the field, in real time. Simulating interactive effects and hazards will augment existing loss reduction tools. By establishing data links to the RVC infrastructure, it will be possible to develop interfaces to live satellite data feeds that provide earth science data based on real world conditions. No currently available commercial system is now capable of this functionality.
In addition to using its subcontractor, Urban Regional Research, as an advisor on potential clients and customers, LNK has signed a Memorandum of Agreement with the University of Maryland Baltimore County, to share data and products pertaining to RVC. LNK has also examined 18 private sector firms which provide products and services in the areas of remote sensing, geographic information systems, 3D terrain modeling, computer image generation, simulation technology, and image processing, for the purpose of establishing strategic partnerships and joint marketing goals.

Project Title: Ultra-high capacity optical memory device
Technical Abstract (Limit 200 words)
We propose to develop a novel holographic volume memory that has ultra high data storage capacity and throughput (in excess of 1012 bits storage and 1 Gbit/second transfer). The proposed method is based on the revolutionary concept of Speckle Wave Multiplexing. The device has a compact architecture similar to conventional optical CD ROMs. We employ a spatially-encoded reference wave that permits recall of stored information by spatially-shifting the mutual position of the encoded reconstruction beam and the storage medium. Entire data pages (in excess of 1 Mbit) can be recalled in parallel. Phase I research will extend existing analytic models of the spatially-multiplexed 3D holographic memory to optimize system design, perform experimental tests to validate the model, demonstrate operation of a scaled memory device and estimate performance of a full scale system. The fully developed system will significantly extend the archival and retrieval data capacity of NASA in terrestrial and spaced based information systems.
Potential Commercial Applications (Limit 200 words)
The proposed holographic volume memory has tremendous commercial potential in virtually every type of computer system for both the federal government and the private sector. In addition, the proposed system is particularly useful for security applications such as banking or proprietary data transfer where access to information needs to be restricted.

A Systematic Integrated Diagnostic
Approach to Software Testing
Technical Abstract (Limit 200 words)
The goal of this work is to leverage QSI's vast
experience and mature software toolset in
Integrated Diagnostics to assist software engineers
in writing quality software with fewer undetectable
defects, an optimized strategy for detection and
isolation of defects, and run-time support for fault
detection, isolation and possible reconfiguration of
safety critical fault-tolerant software. In particular,
such a solution will let a software engineer: a)
assess the testability of software, and suggest
placement of new tests or assertions to improve
coverage and defect isolation; b)identify effective
test sets to execute for achieving appropriate
coverage, while reducing redundancies in tests ;
c)provide optimized troubleshooting procedures to
isolate the faulty code segment or routine in the
event of faulty behavior; and d)provide a run-time
software monitoring and diagnosis capability with
minimal impact on performance by identifying a
minimal set of tests that need to be monitored to
assure software integrity. Our approach is not
aimed at replacing the current test-centric approach
to software testing - it will help design better, more
testable, software with statistically quantifiable
quality, by identifying where to put tests and how to
use them to maximize their benefits.
Potential Commercial Applications (Limit 200 words)
The technology developed here can be applied to
mission and safety critical systems that employ a
mix of hardware and software to perform their
functions. Such systems include:
1. Spacecrafts and satellites
2. Quality control and real-time monitoring of
manufacturing processes
3. Aircraft diagnosis and prognosis
4. Patient health monitoring in Emergency Rooms
and Intensive Care Units
5. Monitoring of hardware and software systems in
safety critical systems, such as the various Wind
Tunnel Systems at NASA, and major power plants.
6. Tele-diagnostics and help desks. Smart agents
for remote maintenance and monitoring.

Project Title: FLC-VLSI Spatial Light Modulators for Optical Memory Read/Write Heads
Technical Abstract (Limit 200 words)
To handle growing needs for storing and accessing extremely large volumes of data such as generated by NASA missions, new high-capacity, high-speed, compact memory technologies are needed. Several companies and research laboratories are developing optical holographic memories that could solve this problem. However, viable systems need specialized, high-speed, electro-optic I/O devices such as spatial light modulators (SLMs). Optical write heads must contain a large number of pixels, must be capable of high-data rates, and must have optical characteristics unique to this application. Efficient recording requires a fixed random phase pattern to be impressed on the data. No existing SLMs have this capability. Displaytech builds SLMs using ferroelectric liquid crystals (FLCs) with speeds up to 10,000 frames/s. We have built 1,280×1,024 pixel SLMs capable of over 2,000 frames/s at data rates exceeding 2.6 Gbit/s. The innovation we propose is to combine two state-of-the-art photonics technologies, FLC SLMs and micro-optics, to build high-speed write heads with integrated random phase masks. We will collaborate with a leader in holographic memory development, Optitek, who will test these devices. We will also collaborate in exploring system architectures that are made possible by the use a advanced SLM and smart-pixel SLM technology for read and write.
Potential Commercial Applications (Limit 200 words)
The proposed spatial light modulator (SLM) is targeted specifically at the emerging, commercial holographic storage industry. In order for these systems to attain the highest possible performance, smallest size, and lowest cost, they need key components such as electro-optic read/write heads which do not now exist. Aside from the obvious uses that NASA has for fast, high-density data storage, the commercial potential of the SLM can be estimated by looking at markets for current mass storage devices such as magnetic media, CDs, and DVD. Every holographic memory system sold will need one or more optical write, or optical read/write heads. The proposed SLM should also be useful for other types of optical and holographic recording, and for optical encryption of two-dimensional data sets.

Project Title: Liquid Crystal Volumetric Three Dimensional Display
Technical Abstract (Limit 200 words)
State-of-the-art 3-D displays have various drawbacks, including the need for the user to wear headgear or glasses, conflicting depth cues in stereo 3-D, requirement for a supercomputer, need for mechanical movement, bulkiness of the system, and limited resolution and bandwidth (in holographic projection, moving screen, and vibrating mirror displays). Physical Optics Corporation proposes to develop a novel solid state liquid crystal volumetric display technology based on three unique electro-optic components: a high-speed VLSI backplane ferroelectric liquid crystal display chip; an electrically tunable variable focal plane liquid crystal micro-lens array; new switchable liquid crystal volume holographic diffusers, controlled by a personal computer. Combining these technologies will make possible a high-speed, large field-of-view, high resolution color multiplanar image projection system without moving parts. The proposed display will be even more commercially attractive because it can be manufactured using low-cost materials and mature fabrication techniques. In Phase I, a laboratory prototype system will be designed and its performance analyzed, and the concept will be characterized by means of experimental demonstrations.
Potential Commercial Applications (Limit 200 words)
NASA applications envisioned include computer generated 3-D displays for spacecraft design, mission simulation, telerobotic remote exploration of planets, and navigation of unknown terrain. Commercial applications will include entertainment (including video games), medical imaging, CAD/CAM, surveillance photogrammetry, training and simulation, air traffic control, navigation, and
shipboard displays.

Project Title Intelligent Information Acquisition
For Aeronautic Measurement and Diagnostics
Technical Abstract
NASA seeks technologies to revolutionize missions in the next century. Accurate Automation
Corporation proposes to fly an enhanced neural network data compression/translated Global
Positioning System (GPS) range system (ENN/TGRS) on the fourth Hyper-X vehicle, scheduled
for launch at Mach 10 in 2001. For this effort, we will develop a prototype of a data
compression neural network; test the neural network on LoFLYTE(TM) (a Mach 5 waverider
shape operated under license to NASA and the Air Force) or one of our other flight test
vehicles; and develop the plan for integration of the ENN/TGRS capability into the fourth
Hyper-X vehicle. This will include analysis of the sensor, instrumentation, and vehicle
modifications necessary to acquire and telemeter interferometric data of the scramjet in
flight conditions. In Phase II we will test the ENN/TGRS system on the LoFLYTE(TM) vehicle,
incorporate it into Hyper-X, and provide the world with the first real-time video
transmission and interferometric data from an operating hypersonic vehicle. Such coupling
of sensor and GPS data will be invaluable, not only for the Hyper-X, but also for future
experimental vehicle research at high Mach, including
the X-33 and X-34 programs.
Potential Commercial Applications
In addition to supporting research on other hypersonic vehicles, such as HyFLYTE, the
commercial applications could be directly applicable to safety of flight issues in the
national airspace. In the event of an emergency, an aircraft equipped with an ENN/TGRS
could instantaneously telemeter all pertinent information from the flight data recorder
(FDR) and cockpit voice recorder (CVR). This would provide extensive information on the
state of the aircraft during emergency procedures, aiding either real-time analysis of the
situation or subsequent analysis by investigators.

An Artificial Intelligence/Fault
Injection-based Approach to Software
Recovery
Technical Abstract (Limit 200 words)
This proposal investigates tools for assessing
increasing the safety
and failure tolerance of safety-critical software. We
propose a
methodology that will allow developers and
certification officials to
assess the safety of software by using simulated
program state
corruptions that are injected into executing
programs. Our approach
uses fault injection techniques to observe whether
program state
corruptions can cause unsafe behavior. These
observations are then
classified using artificial intelligence techniques and
the
classifications form the basis for advanced software
recovery
mechanisms. Hence this technology is able to
derive, build, and embed
recovery mechanisms into safety-critical software
after it is known
that the software suffers from inadequate failure
tolerance.
Potential Commercial Applications (Limit 200 words)
Potential commercial applications include avionics,
medical, nuclear,

3 DOF Roll-Bend-Roll Epicyclic
Anthropomorphic Wrist
Technical Abstract (Limit 200 words)
NASA is committed to developing anthropomorphic
robots and devices to perform remote tasks in
space. Development of sophisticated mechanisms
such as multi-degree of freedom (DOF) hands and
end effectors with numerous wires and possibly
remote motors create demanding constraints on
other system components. Directly addressing this
need, MAR is proposing the development of a 3
DOF anthropomorphic roll-bend-roll wrist that
utilizes an epicyclic power transmission to provide
efficient packaging and a large internal passage
through the center of rotation for routing of wires
and drive cables. This innovative transmission
combines zero backlash planetary gearing and a
triple input differential with a triple load path cable
driven output stage that generates minimal radial
bearing loads and no thrust loads. In-line motors
and drive components produce anthropomorphic
kinematics with all 3 axes intersecting at the center
of the wrist. Joint motion is coupled and all 3 motors
contribute to the output of each axis, producing
wrist capacity up to 3 times that of traditional
designs. Phase I will develop the conceptual design
and perform detailed analysis and prototyping of
key innovative technologies. Phase II continues
R&D efforts producing and testing the 3 DOF
wrist.
Potential Commercial Applications (Limit 200 words)
Commercial applications include telerobotics,
industrial automation, prosthetics, surgical
manipulators, and camera positioning. Significant
features of the technology such as; zero-backlash,
minimal bearing loads, and an unobstructed central
wire passage provide marketing advantages for
epicyclic mechanisms in numerous markets. Three
specific commercial products targeted by MAR are
discussed in Part 10.

Project Title: Rock Driller
Technical Abstract (Limit 200 words)
Solid and annular probes have been used successfully for the disintergration of kidney stones percantainously for many years. This medical technology can be applied to fracturing stones of rocks during planetary exploration. Since these ultrasonic probes generate more than enough energy to pulverize the various types of large kidney stones found in humans they have the same affect on common rocks found throughout the country. In fact, sandstones, shales, etc. are used for testing new designs as kidney stones for lab tests are often difficult to acquire. The ultrasonix systems can be re-designed to suit the space and energy constraints inherent in a planetary exploration vehicle. We will in effect, miniaturize all the hardware but still develop sufficient power to drill, or fracture rocks. We will store and build on the solar energy provided. Upon need, we will pulse through the transducer from the generator in a manner that will cause the probe to hammer into the rocks at approximately 20Khz. The probes can vary in length (approx. 1-20inches and .020-.187 inches) and diameter to meet the requirements. The generator/amplifier will be packaged in a 5x5x3 inch housing to provied a compact unit.
Potential Commercial Applications (Limit 200 words)
The reduction in size and weight will provide the basis for a new medical instrument that will be easier bor the urologist to use as it will be lightweight and less bulky. Additionally, the device could be adapted for drilling fine holes into bones and skulls for the insertion of fine wires and probes for various procedures. Since this technique removes material at a faster rate than drilling with a bit, it is less traumatic, and will not get stuck, or dull. The insertion of fine probes is certainly more desirable procedurally, as opposed to cutting open whole sections of the body to perform the same task.

Project Title: Miniaturized Manipulator Sensing System Using GMR Sensors
Technical Abstract (Limit 200 words)
Sensors using Giant Magnetoresistive Ratio (GMR) materials can offer improvements in size, power, and sensitivity for position and rate sensing in remotely controlled robotic operations in space. GMR materials integrated with on-chip electronics can be very small and light weight and very sensitive to magnetic fields, while operating on very low power. On-chip coils or miniature permanent magnets used in conjunction with GMR sensing materials can monitor magnetic fields, magnetic field gradients, or eddy currents to indicate position (rate) of ferrous or non-ferrous metal manipulators. The intrinsic reliability of GMR sensors (as proven in automotive qualification testing) combined with low power consumption should provide long term surviv-ability in space applications. Using the extensive internal technology base developed for inte-grated GMR sensors, the Phase I Program will study the feasibility of one-, two-, and three-wire GMR sensors for robotic space sensing systems. User needs will be surveyed to determine me-chanical and electrical interface requirements. Preliminary systems designs and feasibility demonstrations will be completed for the most promising applications in Phase I, and working sys-tems will be designed fabricated, and delivered for Phase II.
Potential Commercial Applications (Limit 200 words)
Sensor systems of this type would be applied in many industrial and medical applications, as well as being generally applicable to commercial robotic systems. Automotive applications would include in-bearing sensorsfor ABS pplications, where NVE?s sensors have already passed fleet tests.

Project Title: Compact, Highly Integrated Optical Correlators for High-Speed Image Processing
Technical Abstract (Limit 200 words) NASA, industry, and DOD agencies require
high-speed image processing technologies for machine vision, autonomous vehicles, and searching large graphical databases (such as satellite images). Although electronic processors have made great strides in performance they are still inadequate for many demanding applications because they are either too slow, too large, too expense, or consume too much electrical power.
Due to advances in spatial light modulator (SLM) technology and electronic imaging, it is now becoming feasible to perform key, computationally intensive image processing operations using light instead of electronics. Using an optical correlator, speed improvements of two to four orders of magnitude can be achieved. A difficulty with optical correlators has been that they are typically large, fragile, and expensive. Displaytech's innovation is a very high-level of integration (and small size) in the construction of optical correlators achieved by combining liquid-crystal-on-VLSI SLMs and diffractive optics. The mechanical and manufacturing simplifications inherent in this approach should substantially reduce the cost of building these systems and improve their ruggedness.
Potential Commercial Applications (Limit 200 words)
A large fraction of the customers who buy our SLMs are buying them to build correlators. Commercial markets include fingerprint recognition, machine vision, automated QC inspection for manufacturing, graphical data base searching, and real time image processing for automated manufacturing processes. A significant barrier to the commercialization of optical correlator technology is their high manufacturing cost due to the use of separate components. This proposal presents a solution to this problem which should significantly reduce the cost of manufacturing correlators and make them no more difficult to use than any other computer peripheral. Instead of selling only individual SLMs to our customers, we could instead sell them complete electro-optic correlator modules which will be smaller and cheaper than what anyone could build using separate SLMs.

Project Title: New Balloon Envelope Material Specification
Technical Abstract (Limit 200 words)
The innovation described in this proposal will permit the rapid assessment of new superpressure balloon materials for use as an envelope in the Martian atmosphere and/or in the Earth's stratosphere. The use of scrim reinforced thin films has been considered for many years and occasionally used with polyethylene films. However, the high modulus property, required for superpressure balloons to prevent unstable deformations and resulting altitude excursions, limits the choice of materials significantly. The requirement to "design to cost" for the delivery of a balloon to Mars further limits the choice of materials to those that possess known, reliable properties. Polyester film has been successfully bilaminated to form a composite structure with the necessary strength, weight, and permeability at low temperatures. Although, the scrim reinforcement adds weight, it gives the resulting composite material the tear strength that is absent in the base material. This Phase I research will demonstrate the effect of packing density on the gas loss properties of two layers of three micron polyester film bilaminated with light weight scrim reinforcement.
Potential Commercial Applications (Limit 200 words)
The development of a superpressure balloon material with an areal density of half that of the thinnest nylon film available would create the potential for a new type of free floating communication relay network. This new material will make it possible to fly higher than previously considered possible with lighter payloads. However, electronic miniaturization is proceeding at a fast pace and the envisioned network may be possible in the future with extremely light weight components. The stratospheric network will make possible global communication from a cellular telephone at a fraction of the cost today. One balloon could provide telecommunications capability for the entire island of New Guinea where the terrain would make conventional transmission systems cost prohibitive. The commercialization of the stratosphere is waiting for the successful emonstration of this innovation.

Planetary Rover Navigation Using
Landmark Recognition
Technical Abstract (Limit 200 words)
We propose to develop an automatic landmark
recognition system for autonomous navigation of
planetary rovers. Navigation on other planets and
moons is complicated by variable quality terrain
maps and the lack of a Global Positioning System.
Supervised navigation using imagery from the
rover's cameras has been demonstrated with
Sojourner, but future NASA missions call for
completely autonomous navigation over many
kilometers. To support this goal, we will design an
image-based navigation system that provides
autonomy via automatic identification of landmarks.
We will compare the use of imagery from
conventional camera configurations with imagery
from very wide angle views (up to 360°) which can
capture many landmarks in one image, potentially
providing better localization precision and
reliability. Once a landmark has been recognized
and its position correlated with an internal map, that
landmark can be used as a reference point to fix
relative bearings; multiple bearings providing a
position fix. Many such fixes over time provide
optimal dynamic estimates of changing rover
position. Key innovations are the coding of
landmarks in highly compressed form, as feature
vectors, and the use of a state-of-the-art
hierarchical neural network feature classifier for
view-and-lighting invariant recognition of many
similar landmarks.
Potential Commercial Applications (Limit 200 words)
Future NASA missions will benefit from the
localization accuracy and reliability provided by our
landmark recognition method. Commercial
applications for robotic appliances using our
navigation system include automated food delivery
in hospitals, mail delivery and vacuuming
throughout office buildings.

Real-Axis Programmable Spatial Light
Modulator for Compact and Rugged
Optical Correlators
Technical Abstract (Limit 200 words)
The success of optical correlators based on
programmable SLMs has led to the desire for
implementing the same functionality in a compact,
rugged package for use in space, military, and
industrial applications. Boulder Nonlinear Systems
(BNS) proposes to draw on its expertise in the
development of high-speed binary and multi-level
SLMs to develop a high-resolution, high-contrast,
light-efficient, multi-level SLM specifically for
integration into compact and rugged optical
correlators. The proposed device leverages a
$450,000 investment in a high-speed 512x512
multi-level SLM. This device lacks the required
optical contrast, light-efficiency, and small pixel
pitch required to build a compact, rugged optical
correlator. BNS proposes during Phase I to perform
advanced techniques for die-scale planarization of
the optical surface of our 512x512 multi-level
modulator; and liquid crystal alignments. The
combination of these should yield a high-contrast,
light-efficient, multi-level 512x512 SLM. During
Phase II, a new 512x512 SLM would be developed
utilizing these advances, as well as implementing a
smaller pixel pitch. The combination of the smaller
pixel pitch and the improved optical quality would
yield a near optimum SLM for compact, rugged
optical correlators. As the only current supplier of
high-speed analog SLMs, BNS is highly qualified to
complete such a program.
Potential Commercial Applications (Limit 200 words)
BNS has built substantial business around our
SLMs because we have designed them exclusively
for optical processing applications. This focus of
design objectives has so far resulted in three
successful SLM products, the 128x128 binary
SLM, the 256x256 binary SLM, and the 128x128
multi-level SLM. Most of our customers select our
product because our primary competitors are only
interested in the high volume display market, and
hence their products do not meet all of the
specifications that are important to the optical
processing community. Since the introduction of our
128x128 multi-level SLM, we have received
numerous requests for a higher resolution,
high-speed, high-contrast, multi-level SLM such as
the 512x512 SLM that we are proposing. Potential
customers that have shown interest in this
development include those in optical correlation,
holographic storage, beam steering, 3-D display,
printing, and optical computing. These inquiries
have come from the space, military, commercial,
and academic communities in our country as well as
abroad. With the successful completion of the
proposed Phase I and II efforts, we will be in a
position to offer this 512x512 SLM as a product,
the likes of which cannot currently be found
anywhere.

Project Title:
Interactive User Interface for
Telerobot Control
Technical Abstract (Limit 200 words)
Standard robot programming languages require
users to explicitly specify trajectories for any task
to be performed by the robot. In applications where
the environment and task change, it is difficult to
develop hard-coded programs using existing
programming tools. If robots are to share in
space-related tasks and function as more than
teleoperated slave devices, entirely new types of
programming mechanisms and user interfaces must
evolve. In this project a Teach By Showing (TBS)
system will be developed that observes and learns
from the performance of the teleoperator,
producing a sensor-driven procedural program from
those actions. The operator can associate a subtask
name with the learned actions and later invoke that
subtask to perform some portion of his/her
workload autonomously. During Phase I, the
method will be demonstrated in a simulated docking
application. As more and more subtasks can be
performed autonomously, the effects of time delay
may be less significant, possibly permitting ground
personnel to assume more control of robot
operations. Since ground-based Shuttle and Space
Station component mock-ups exist for training and
contingency planning, an intriguing scenario would
be to teach selected manipulator tasks on the
ground and up-load the TBS-produced programs for
execution in space.
Potential Commercial Applications (Limit 200 words)
Immediate benefits can be realized at commercial
and military installations where robots are currently
used in unstructured environments. Examples
include: terrestrial construction; space and
underwater construction, maintenance, or
exploration; transport and handling of hazardous
materials; tasks in environments hazardous to
humans such as nuclear facilities, munitions
handling, and firefighting; and in automated
manufacturing.

Project Title: Narrowband Filters for Optical Space Communication Systems
Technical Abstract (Limit 200 words)
Accuwave will develop a complete line of narrow-band holographic Bragg grating (HBG) filters with bandwidths ranging from a few Angstroms to sub-picometers. The filters will cover wavelengths ranging from 300 nm to infrared. These filters will be distinguished by high throughput (>60%) and excellent out-of-band rejection properties. They will have considerably smaller dimensions, lower weight, and lower cost than other filters with comparable performance.
Potential Commercial Applications (Limit 200 words)
Free space optical communications systems for commercial satellite systems, terrestrial wireless links, LIDAR and remote sensing receivers. In addition, the filters can be used in instrumentation and astronomical research filters.

Project Title:
Ka-Band MMIC for Spacecraft
Transponders
Technical Abstract (Limit 200 words)
The transponder on-board spacecraft is made of a
receiver for up-link
command and a down-link for data transfer. For
small spacecraft used
for deep space exploration, the microwave
transceiver for those
functions must be small and rugged and consume
little DC power.
Microwave Monolithic Integrated Circuits (MMIC)
offer methods of
integrating functions of such transponders into a
few IC chips, and,
thus, increasing the performance capabilities of
transponders.
While X-band MMICs for SHF down-links are
being developed, additional
MMIC capabilities are needed to enable
integration of EHF (Ka-band)
transmitters. This proposal addresses that need,
and describes
several optional approaches of implementing a
Ka-band transmitter by
adding a frequency multiplier, a converter, a
modulator, or
combinations of those to an existing SHF
transmitter. For all of the
proposed transmitter configurations, MMIC chips
may be designed using
conventional commercial gallium-arsenide MMIC
processes. Examples of
MMIC designs and expected performance
characteristics of various MMIC
chips are presented. The proposed program would
lead to definition of
the optimum approach, selection of MMIC
architecture, and feasibility
demonstration of MMIC performance. The ensuing
Phase 2 program will
be structured for MMIC design/fabrication and
demonstration.
Potential Commercial Applications (Limit 200 words)
The outcome of the proposed program will lead to
introduction of
low-cost generic MMICs that may be used in
commercial (as well as
military) telecommunications equipment. Such
MMICs may be used in:
ground stations for 20/30 GHz satellite
communication systems, local
multi-point distribution systems (MDS), and 38
GHz point-to-point
radios.

Project Title:
A Low-Power, Low-Cost electron gun
for Microwave Power Modules
Technical Abstract (Limit 200 words)
The microwave power module (MPM)is seen by
many as the most promising means to satisfy
exploding demand for transmitters in today's hot
communications market. But it must be compact,
efficient, reliable and --above all--cost effective. A
critical component is the vacuum tube power
booster, normally a traveling wave tube (TWT).
The TWT has resisted efforts to reduce it to
commodity status via mass producitns techniques
such as are used on its cousin, the CRT. Substantial
progress toward this goal could be realized with an
improved, standardized electron gun. This
component very largely determines the
performance, efficiency, life span, and cost of the
TWT.
We propose a new electron gun design that utilizes
a low power, miniature dispenser cathode. This
electron gun will dissipate less than 1.5W of power
and will be of generic design so that it can--with
slight modification--be used at most frequencies and
powers in many different TWT's. Thus, it aids in the
process of standardization--a necessary step if low
cost MPM's are to be realized. It is also very
compact and can be built entirely on automatic
equipment. Parts are joined entirely through spot
welding or mechanical capture. This reduces the
cost to below $40. We propose a program of study
and development plus prototype construction.
Potential Commercial Applications (Limit 200 words)
The target market for this device, MPM's
(microwave power modules) have many commercial
applications: telephone transmission, mobile and
satellite communications, television, data links,
military systems, etc.

Project Title:
Low loss Ferroelectric Films Grown on
Ferrite Substrates for Adaptive
Microwave Applications
Technical Abstract (Limit 200 words)
The rapid expansion in the use of microwave
communications has created a need for dramatically
improved microwave devices. In many applications
of microwave electronics, it is often necessary to
tune the electrical characteristics of a microwave
signal. Ferroelectrics and ferrites are the materials
of choices providing the electrical and magnetic
tunability for adaptive microwave devices,
respectively. The adaptability will be increased
significantly if a microwave device combines both
the electrical and magnetic tunability. NZ Applied
Technologies (NZAT) already demonstrated the
use of its propriety metalorganic chemical liquid
deposition process (MOCLD) to produce tunable
ferroelectric microwave filters. The process is
suitable for low-cost high-volume manufacturing.
NZAT proposes in this Phase I program to use its
MOCLD expertise to grow low loss ferroelectric
films on ferrite substrates and open the door
leading to a new generation of microwave devices
which have the electrial and magnetic dual-tuning
capability.
Potential Commercial Applications (Limit 200 words)
Success in the Phase I effort will lead to the
commercial fabrication of a new generation of
tunable microwave devices. These advanced
systems will have great applications in space,
military, industrial, medical, and consumer sectors.
Such as tunable phase shifters, tunable filters, and
tunable beam scan antennas.

Project Title: Bandwidth- and Power-Efficient, High Rate Burst Modem
Technical Abstract (Limit 200 words)
Over the past six years, SiCOM has researched two related areas of communications systems. The first area was devoted to Gaussian Minimum Shift Keyed (GMSK) modulation, the rapidly emerging global standard modulation format. The second area was related to developing efficient burst demodulation. These efforts have yielded innovative concepts that provide significant advantages in both areas. An M-ary form of GMSK, Inter-Symbol Interference (ISI)-free modulation, referred to as MGMSK, which has constant envelope and can be used with trellis coding was developed on SiCOM internal R&D, and characterized under a prior Phase I SBIR contract. Additionally, a new method of coherent demodulation of burst signals was developed on a separate Phase I SBIR.
Objectives of this proposed Phase I effort will be to determine the feasibility of combining MGMSK with the improved coherent burst demodulation method. This contract would determine the system sensitivities to implementation egradations, define a system architecture, and generate a plan for the Phase II effort. During Phase II, a demonstration unit will be developed and built to demonstrate the exceptional performances of a coherent MGMSK burst demodulator---spectral efficiency, power efficiency, multiple bits per symbol, and constant envelope operation.
Potential Commercial Applications (Limit 200 words)
The MGMSK family of burst modems to be developed under the proposed project will be applicable to a number of very large markets including: Local Multipoint Distribution Services (LMDS),Broadband Fixed Satellite Services (FSS), Terrestrial Microwave (LAN/WAN wireless interconnect, private video distribution, wireless cable, wireless fiber, coax), Very Small Aperture Terminals (VSAT), military communications, space-airborne communications and mobile communications. These modems will serve niches in these markets where spectral efficiency and large savings in cost and power dissipation of output amplifiers enabled by MGMSK provide substantial market leverage.
MGMSK modem products will be of particular value to communications terminals using active planar array antennas (which require saturated-amplifier operation to keep power dissipation low), and to mobile terminals (where battery life is crucial).

Project Title:
A CVD Diamond Coated Silicon-Based
Cold Cathode For Space-Based Power
Tubes
Technical Abstract (Limit 200 words)
A silicon based Spindt-type field emission cathode
exploiting electron emission properties of Chemical
Vapor Deposited (CVD) diamond will be developed.
This cold cathode will be capable of producing high
current densities at low applied electric fields and
will dramatically improve the performance of
microwave power tubes and other electron devices
for commercial and military applications. A
proprietary process is employed for selective
diamond deposition on emitter tips of silicon based
field emission arrays produced by state of the art
semiconductor manufacturing technologies. This
process which produces coverage of diamond
crystallites on emitter tips with no coverage of the
gate has been developed by General Vacuum, Inc.
and successfully demonstrated on Mo based
Spindt-type arrays provided by NASA LeRC. Due
to the Negative Electron Affinity (NEA) nature of
diamond, high electron emission will be achieved at
very low applied fields. Because power in satellites
can cost up to $1,000,000 per watt, very significant
savings can be achieved with the new diamond/Si
cold cathode since no heater is necessary to obtain
the desired current densities and input power is
orders of magnitude lower than state of the art.
Phase I will demonstrate feasibility of reproducing
this process on silicon-based field emission arrays.
Potential Commercial Applications (Limit 200 words)
Diamond-coated silicon-based Spindt cathodes may
be incorporated into high power amplifiers for
Doppler radar systems, satellite communication
systems, and field emission cathodes for flat panel
displays. These arrays will be a highly efficient
source of electrons, at high power, for commercial
communication systems and next-generation field
emission displays. The manufacturing technique is
easily incorporated into existing silicon-based
semiconductor manufacturing processes, and will
allow rapid incorporation of thin-film diamond to
enhance existing devices. The efficiency and yield
of these arrays will also allow the design of new
devices which had previously been limited by
conventional thermionic or cold cathodes.

Lightweight Mirrors for Optics
Technical Abstract (Limit 200 words)
Silicon carbide (SiC) is a good candidate material
for use as substrates for laser mirrors, solar
collectors and concentrators, astronomical
telescopes and optics in vacuum-ultraviolet and
X-ray regions, since it displays a unique
combination of material properties such as high
elastic modulus, low coefficient of thermal
expansion, high thermal conductivity and low
density besides excellent oxidation and rain erosion
resistance. It is especially suitable for space
applications since it has adequate cryogenic
stability and high resistance to degradation from
atomic oxygen, trapped charges such as electrons
and protons, and high-energy photons. SiC obtained
from sintering, hot pressing or reaction-bonding
process is usually porous and multiphased material,
which does not produce a good optical surface. An
overcoat of CVD Si or SiC is required to eliminate
porosity and increase optical quality. In this Phase I
effort, MMI will synthesize nanoscale Si/SiC
powders using a combination of sol-gel/microwave
plasma processing technique. The nano SiC
powders will be consolidated by microwave
sintering and coated concomitantly with
nanocrystalline silicon powder. Nanocrystalline
silicon particles will enhance densification by liquid
infiltration and provide a homogeneous coating
together with isotropic properties besides
facilitating polishing. The centrifugal float polishing
technique developed by MMI will be used to polish
the lightweight mirror Si/SiC substrate to an optical
surface finish of < 1nm roughness.
Potential Commercial Applications (Limit 200 words)
Space applications with adequate cryogenic stability
and high resistance to degradation from atomic
oxygen, reaction tubes and furnace components in
semiconductor processing, optical materials for
synchrotons, vacuum ultraviolet and x-ray
applications, solar collectors and concentrators.

Optimizing the Design of an Integrally
Formed Optical Bench, Constructed of
Carbon Fiber Reinforced Silicon
Carbide (C/SiC)
Technical Abstract (Limit 200 words)
Carbon Fiber Reinforced Silicon Carbide (C/SiC) is
a new, light-weight, high-strength engineering
material that features tunable mechanical and
thermal properties, in conjunction with a low cost,
rapid fabrication process that produces near net
shape parts using conventional CNC
machining/milling equipment. With regards to optics
and optical structures, the tunable properties of
C/SiC are superior to graphite/epoxy (Gr/Ep), the
state-of-the-art structural material of recent years.
The objective of the proposed investigation is to:
(1) carry out a series of detailed, high-quality tests
of the mechanical
and thermal properties of C/SiC over its full tunable
range -- from optical
grade to structural grade (i.e., from high
stiffness/high brittleness to
lower stiffness/greater ductility);
(2) confirm the test results by comparison with
earlier, less detailed tests of C/SiC by other
investigators; and
(3) optimize the design of an integrally formed
optical bench (using a finite-element computer
program) by specifying the appropriate choice of
C/SiC mechanical and thermal characteristics for
the bench's various components, namely the struts,
plates, and joints.
The bench design will have relevance to the
requirements of a variety of spacecraft, such as the
Next Generation Space Telescope and other future
space telescopes, Earth-observing satellites,
telecommunication satellites, and airborne
instrument packages.
Potential Commercial Applications (Limit 200 words)
In addition to NASA applications such as the Next
Generation Space Telescope, the Terrestrial Planet
Finder, Space Infrared Telescope and other
missions, C/SiC, due to it's tunable properties, has
been identified to have an extremely broad market
place for commercial applications, including, but not
limited to:
telecommunications satellites, surveillance
satellites, airborne instruments and packages,
antenna systems, thermal protection systems,
engine components for automobiles, aircraft, and
rockets, bio-compatible replacement parts, etc.

Project Title: Ultra-Smooth As-Grown Silicon Carbide Films for EUV Mirrors
Technical Abstract (Limit 200 words)
Silicon carbide is a superior material for the fabrication of lightweight mirrors for the extreme ultraviolet. However, these mirrors require a super smooth finish to eliminate scattering of these very short wavelengths - ypically 2-3 angstrom rms. Current state-of-the-art technology employs CVD SiC for the final mirror overcoating, which is then super-polished. SKION proposes to employ its unique negative metal rectilinear ion beam deposition (RIBD) technique to fabricate high quality silicon carbide mirrors with a super smooth finish without the need for a final polishing step. The need for polishing is eliminated because RIBD films actually become smoother during deposition,
unlike any other film deposition process. This innovation will make possible the fabrication of mirrors which (1) have less surface contamination from polishing (2) can be fabricated to final dimensions more accurately, since thinner overcoats can be used (3) need no high temperatures during the overcoating process (unlike CVD which requires temperatures up to 1300oC), reducing cracking and distortion, and (4) are considerably less expensive than any currently
available. The innovation addresses the need set forth in Topic 27.01 for novel materials and fabrication techniques for silicon carbide optics.
Potential Commercial Applications (Limit 200 words)
High quality, super-smooth SiC films will improve the quality and lower the cost of military and space optical components, including mirrors and gratings. These SiC films also offer a breakthrough for electronic devices which can block high voltages, switch high current densities, and operate at elevated temperatures in the range of 500 to 700oC as encountered in missiles and aircraft.

Fabrication and Polishing of Uncoated
Silicon Carbide Aspheric Optical
Surfaces
Technical Abstract (Limit 200 words)
Silicon Carbide (SiC) optics are a key technology
for future NASA missions including Next
Generation Space Telescope (NGST). SiC has
superior thermal stability and excellent specific
stiffness making it ideal for space based system
applications. Flat and spherical optical surfaces can
be obtained directly on SiC materials using
conventional polishing systems. The problem has
been in obtaining non-symmetric aspheric surface
profiles (i.e.;hyperbolic, elliptical or parabolic
contours). A common solution is to coat SiC optics
with a thin layer of silicon prior to optical finishing.
Silicon can be easily polished and the slight
coefficient of thermal expansion (CTE) mismatch
between SiC and silicon is not an issue for most
applications. SSG proposes to develop an
innovative fabrication process which will facilitate
polishing of uncoated SiC aspheric optical surfaces.
The proposed approach will modify and improve the
casting, machining and polishing steps in SiC
fabrication. Several innovative techniques will be
used including diamond micromachining, automated
lap polishing, high speed spot polishing, flow
polishing and ion figuring. SSG has already done
some preliminary work in these areas, producing a
0.75 wave pk-valley off-axis parabola in a 4.5"
diameter SiC sample. The effort proposed will
provide SiC optics which are superior to the current
state-of- the-art silicon coated SiC optics in several
ways: improved thermal stability, improved
reflectivity in the EUV spectral region, reduced
manufacturing cost/time, and eliminating residual
stresses created by the silicon coating process. In
Phase I SSG will develop and refine the innovative
manufacturing process proposed. The viability of
the techniques proposed, and the improvements
obtained with the uncoated SiC substrates, will be
demonstrated by fabrication and testing of a
proof-of-concept off-axis parabolic reflector.
Potential Commercial Applications (Limit 200 words)
The availability of cost effective, bare SiC aspheric
optical surfaces will open up a number of important
commercial applications. Reductions in cost, and
improvements in EUV reflectivity and thermal
stability make the technologies proposed here very
interesting for EUV lithographic projection optical
systems. SSG has already begun discussions with
Silicon Valley Group (SVG) Lithography with
regard to transitioning the optical
fabrication/polishing processes referenced here.

Tunable, Single-Frequency, Fiber
Fabry-Perot Surface Emitting Lasers
Technical Abstract (Limit 200 words)
Micron Optics Inc. proposes a novel, compact,
tunable, and single- frequency semiconductor- fiber
laser that combines a semiconductor quantum-well
vertical-cavity surface-emitting laser (SEL) within a
fiber Fabry-Perot (FFP) cavity. The "half-cavity"
SEL consists of one semiconductor Bragg reflector
as the bottom mirror and a multiple quantum well
(MQW) gain region. The top output mirror is
formed strictly by a direct fiber dielectric mirror or
a fiber waveguide dielectric mirror. The
combination of "half-cavity" SEL and fiber mirror
forms the fiber Fabry-Perot surface-emitting laser
(FFP-SEL). Wavelength tuning can be achieved by
air-gap tuning inside the FFP-SEL cavity.
FFP-SELs should enable (1) robust
single-frequency and thus narrow-line lasing in the
near-IR spectral region, (2) continuous wavelength
tuning, (3) wide frequency (wavelength) tuning
range >10,000 GHz, (4) moderate power levels
(>2mW), (5) small and compact device structure,
and (6) low power consumption. These laser
performance characteristics should provide elegant
and enabling solutions to NASA's need for
precision metrology, interferometry, and Doppler
measurement at a variety of near-IR wavelength
regions.
Potential Commercial Applications (Limit 200 words)
The proposed single-frequency tunable laser
sources are the basic building components in
fiber-optic communication systems, sensing, and
spectroscopy. The success of FFP-SELs should
enable (1) the exploitation of the vast bandwidth
potential of optical fibers that leads to subsequent
advances in Information Technology, (2) distributed
fiber grating sensing for structural health
monitoring and smart structures, and (3) advanced
applications in spectroscopic remote-sensing and
trace-level monitoring of a broad range of
chemicals such as those of critical interest in
manufacturing processes and traditional
environmental monitoring.
In general, hybrid tunable laser structures
incorporating discrete bulk optical compoenets
have complex mechanical requirements and
incompatible mode-field coupling between lasers
and tuning elements, and thus do not lead to rugged
and cost-effective implementations for
commercialization. The requirement for tunable
lasers that are fiber-compatible, robust, and
cost-effective makes the FFP-SEL an attractive
candidate.

Project Title: Solid State Electro-Optic Tuneable Fabry-Perot Filters (SSET-FAB)
Technical Abstract (Limit 200 words)
This initiative designs and fabricates a robust solid state tunable filter for use in the 4000 Å - 16000 Å range. Two specific systems for narrow band remote sensing applications are developed. The first provides spectral resolution of better than 1 Å tunable over 1000 Å from 4000 - 16000 Å. This system is optimized for spectral rejection of the daytime Rayleigh background; The second system provides a spectral resolution of 0.02 Å resolution tunable over 32 Å in the same region. The methodology utilizes Fabry-Perot etalons with index variability provided by nematic liquid crystal control. These fully developed, mutiple etalon systems to be supplied in Phase II are based upon the design and fabrication of a single etalon with a 80 mm etalon spacing in Phase I. cientific Solutions Inc. (SSI) has pioneered and demonstrated liquid crystal Fabry-Perot LC-FP) etalons with resolutions lower than the 1 Å proposed here, and higher than the 0.02 Å resolution application. As such, this project expands a demonstrated innovation to intermediate resolutions specifically appropriate for daytime LIDAR applications, as one example. These LC-FP filters feature electronic tunability, vibration and radiation insensitivity, high throughput, and light weight design that are unmatched by any other current technology.
Potential Commercial Applications (Limit 200 words)
An LC etalon is a single, lightweight unit, nearly impervious to vibration or shock. As such it is an ideal component for chemical imaging or spectroscopy systems for use in space or other hostile environments (manned aircraft, nmanned arial vehicles etc.). In addition, electronic spectral tunability of four etalons simultaneously is accomplished with very little power ( less than 200 mA at 12 V) and no moving parts. The capabilities and of the filter systems we provide are thus well adapted to NASA requirements for smaller, lighter systems for on-orbit, airborne, or sub-orbital platforms. The proposed tunable filters are also well suited to narrow band isolation required in LIDAR and general laser applications. Beyond that, numerous commercial concerns express interest in tunable filtering. Environmental and related applications can benefit from the ability to remotely identify chemical cloud composition and to precisely determine location and abundance of toxic chemicals. Both the textile and paper industries have communicated interest in robust, easily tunable filters for the purpose of monitoring product uniformity and defect frequency.

Project Title: Laser Pattern Generator for the Fabrication of Blazed Diffractive Profiles on Conformal Surfaces
Technical Abstract (Limit 200 words)
Although many technologies exist for the fabrication of diffractive optical elements (DOEs) on planar surfaces, there does not exist any fabrication method that can produce continuous-relief DOE patterns of arbitrary symmetry on conformal surfaces. Rochester Photonics Corporation (RPC) proposes that a laser pattern generator (LPG) capable of addressing a three-dimensional work volume can address this dilemma. RPC is currently developing a conformal laser pattern generator that is capable of fabricating binary structures. RPC proposes to modify this LPG in order to perform grayscale exposure of photoresist-coated conformal surfaces. The resulting grayscale features can be transferred into a bulk material or into a replication polymer for high-volume production. For arbitrary surface and diffractive geometries, a single-point writing system is the only option. RPC is ideally suited to develop such a technology since it has five years experience in LPG-writing of planar continuous-relief structures, having designed and fabricated two LPG machines. The developed technology for patterning conformal surfaces will give optical designers increased design freedom, result in more compact optical systems, and will benefit such applications as curved focal plane arrays, wavelength demultiplexing, and imaging spectrometers.

Project Title: Low-Cost Manufacture of Glass Diffractive Optics
Technical Abstract (Limit 200 words)
The development of diffractive optical elements is opening the way to new and improved applications for both space and terrestrial requirements. Depending on the methods of fabrication, the reproducibility, capital investment, and operating cost may limit the availability and thus the application of these elements. Therefore new, cost-effective fabrication methods are required. In this Phase I proposal, the feasibility of a low-cost replication technique is explored for mass producing diffractive optics at a fraction of the cost of existing methods. The resulting diffractive element is in a high quality glass. The program objectives include process investigations for fabricating high quality optical elements, and an assessment of feasibility and limitations. The replication of both binary and continuous diffractive surfaces will be pursued. The proposed approach is potentially suited for a wide range in element size with surface features having different geometries, characteristics either difficult or impossible to produce by other methods, especially in large quantities and at low cost.
Potential Commercial Applications (Limit 200 words)
Diffractive optics can be used in a number of applications, including lenses and other optical elements, athermalization or achromatization of optical systems, aspheric testing, coherent beam addition, and beam steering, scanning, and storage. Other applications are array generation, imaging, optical interconnects, endoscopy, displays, sensing, antireflection coatings, fiber optic multiplexer/demultiplexers, filters, and optical computing.

Project Title:
High Frame-Rate Analog SLM for
Active Diffractive Optics
Technical Abstract (Limit 200 words)
Spatial light modulators (SLMs) for implementing
active diffractive elements place unique demands
on both the modulator and the addressing structure.
The modulator is ideally analog phase-only, with at
least one wave of modulation depth, and a
reconfiguration time that is ideally sub-millisecond.
The addressing structure can update imagery at a
similar rate, is light efficient, optical quality, and
has a high pixel density. An SLM component such
as this does not currently exist. Boulder Nonlinear
Systems proposes to use expertise in liquid crystal
phase shifters and draw on experience in very large
scale integrated (VLSI) circuits and high speed
drivers to build an SLM that satisfies the required
specifications. As the only current supplier of high
frame rate analog SLMs, BNS is qualified to
successfully complete such a program. The program
would leverage a current $450,000 investment
specifically in the 512x512 development.
Potential Commercial Applications (Limit 200 words)
BNS is dedicated to providing SLM products to
customers in non-display applications. Our study of
the market indicates that a 1kHz frame rate,
512x512 analog SLM with 15 micron pixels is
optimum for meeting the needs of most of these
customers. In addition, optical quality specifications
must be met that mandate planarization on the
VLSI addressing structure. Applications that are
targeted include active diffractive elements, target
tracking (such as beamsteering), optical pattern
recognition, atmospheric correction (adaptive
optics), interconnects, and optical data storage.
BNS intends to build an optical correlator
subsystem product around the 512x512 engine for
addressing high data reduction problems in machine
vision. This includes inspection of manufactured
parts and medical imaging, such as papsmear.

Project Title: Proximity Printing of Micro-Optics Using Phase Shifting Masks
Technical Abstract (Limit 200 words)
NASA has expressed a need for innovative fabrication methods for diffractive optical elements (DOE's). Such innovations are needed to fully exploit the inherent possibilities of DOE's to increase performance and to reduce the size, weight, and cost of optical systems. A prevalent limitation of diffractive technology is the inability to fabricate components with small enough feature sizes for optimum performance for many designs, particularly over large surface areas. DOC is proposing an innovative approach for fabrication of micro-optical components that makes use of the interference properties of phase shifting masks (PSM's). PSM's are used to introduce a controlled interference effect to lithographic exposures to enhance the effective resolution and depth of focus. While PSM techniques have seen extensive use in the microelectronics industry, these methods have not been applied to fabrication of diffractive and micro-optical components. Using this approach, it will be possible to make optics with smaller features and periodicities than can be made with conventional technologies. In addition, it is feasible to use interference effects to manufacture micro-optics with new properties and structures that are not practical to fabricate with more conventional methods. These methods should provide a cost-efficient method of fabricating submicron diffractive structures over large surface areas.
Potential Commercial Applications (Limit 200 words)
Development of the fabrication techniques outlined herein will benefit a range of industries, including the telecommunications and laser machining markets. Other industries that use anti-reflection coatings for high-powered laser applications will also benefit.

Project Title: Fluorescence Instrumentation for Cell Biology Microgravity Research
Technical Abstract (Limit 200 words)
The Space Station Biological Research Program at NASA Ames is funding the development of a CellCulture Unit (CCU) to support microgravity research in cell biology onboard the Space Station. The CCU will provide basic and essential infrastructure for space-based cell biology research. However, its full utilization will require additional instrumentation with fluorescence capabilities for quantitative cell analysis. We propose a next-generation instrument, which could be used as an adjunct to the CCU to bring sophisticated applications of molecular biology and fluorescence spectroscopy to the study of cell biology onboard the Space Station. The instrument will initially be aimed at performing measurements of intracellular calcium signals in living cells although it has much broader applicability. The instrument will be rugged, compact, with low mass and low power consumption. This technology will bring into space powerful research tools that are now only available in ground-based laboratories and which require large, heavy, delicate, expensive and power-hungry instrumentation. Areas of fundamental interest in microgravity research such as signal transduction, cytoskeleton organization, and many other cellular processes would become amenable to study in space for the first time. No instrumentation exists with the capabilities of the proposed instrument.
Potential Commercial Applications (Limit 200 words)
A compact, rugged instrument capable of utilizing single-wavelength dyes to measure lifetime-based fluorescence of numerous cellular processes could be a very exciting addition to an already competitive market. The broad applicability of the proposed instrument would allow for a variety of cell systems to be monitored. A version of the instrument could also be reconfigured for application in the pharmaceutical industry as an advance for high throughput screening.

Project Title:
Tri-Spectroscopy Interferometric
Micro-imaging Sensor
Technical Abstract (Limit 200 words)
MEDECO proposes to develop a true multiple
spectroscopy sensor in a single, compact package.
The TRI-SPECTROSCOPY
INTERFEROMETRIC MICRO-IMAGING
SENSOR, TIMS, provides for reflectance, Raman,
and fluoresence spectroscopy in a multifunctional
hyperspectrometer for extreme circumstances,
including microscopic studies of leaf cellular
structure, microbial mats, in situ hot springs
species, studies 'at depth' in oceans, and
gravitationally deployed for hard penetration into
ground/soil samples or ocean sediments.
TIMS enables measurement of hyperspectral
properties for organic and mineralogical species at
diverse sites in the presence of water, which blocks
infrared wavelengths, and has the capability to
acquire image cubes for diverse biological and
mineralogical samples resolved into size domains of
10 microns or smaller, as demonstrated herein.
TIMS innovations are summarized as follows:
> New interferometer design with two-orders of
magnitude pixel illumination gain.
> Multifunction capabilities for diverse
hyperspectral diagnostics in wet or dry samples.
> In situ Raman, fluoresence, and reflectance
hyperspectra.
> Direct images of the hyperspectral field of view.
> Microscopy at 10 microns or smaller dimensions.
> Penetrator capability with 360 degree field of
view.
> Observations of motile species.
> Observations in boreholes, thin section
microscopy, or microscopy of opaque or transparent
samples.
> Ruggedized for sustained operation under
extreme circumstances of temperature, pressure,
acceleration, or in chemically active environments.
Potential Commercial Applications (Limit 200 words)
MEDECO plans to propose this sensor for
inclusion in the sensor suites for NASA's program
for Mars exploration and other solar system
bodies' exploration. The low power, mass, and
volume requirements of a ruggedized TIMS is well
suited to those missions. TIMS has market
potential as a sensor for extreme environments
encountered in industry, in the ocean, and
particularly for medical diagnostics where the
multifunctional measurements together can provide
a better spectroscopic determination for
hemodynamics than any single function sensor.
There is also a potential market for TIMS as a
handheld "geologist's or environmentalist's hand
lens" where the sensor serves as a field tool for
prospecting and/or on-site pollutant analysis.

Project Title: Detection and Quantitation of Rare DNA
Technical Abstract (Limit 200 words)
The study of evolutionary phenomena relies increasingly on the analysis of genomic DNA sequences, including fossil DNA. Because the samples to be studied are often available only in extremely small quantities, the capability to conduct analyses at very low copy number is essential. While PCR techniques have allowed detection down to a single copy, quantitation at very low copy number (less than a few hundred copies)has remained an unrealized goal.
BioTraces proposes the development of a quantitative direct detection of DNA method based on the ultrasensitive Multi Photon Detection (MPD) technique. MPD allows the detection and measurement of sub-zeptomole quantities of certain radioisotopes, including Iodine 125. Using a combination of MPD and BioTraces' proprietary SuperTracer technology, whereby several hundred radiolabels can be conjugated to a single DNA strand, detection of about ten copies and quantitation of a few tens of copies of DNA is expected.
Potential Commercial Applications (Limit 200 words)
The methods to be developed herein are generally applicable to DNA detection and quantitation for life science research and medical diagnostics. Quantitative direct (nonamplification) DNA detection assays at the level of 20-50 copies of DNA would be commercially important for detection of infectious diseases, cancer detection, and viral/bacterial load monitoring in connection with therapeutic treatment. The potential market for such assays is in excess of $1 billion per year.

The proposed Imaging Interferometer is responsive to Topic 1, Earth Remote Sensing, with applications in multispectral thermal imagery and remote spectroscopy for atmospheric sounding, and monitoring of ozone, greenhouse gases, and pollutants.
Specfic project objectives include: fabrication and characterization of a wavefront-dividing interferometer (WDI); set-up laboratory-scale imaging interferometer containing WDI, IR-CCD camera, and readout/data processing system; development of image correction algorithms for background and pixel response variability; and measurement of spectral images from known point sources and 2-D test patterns.
It is anticipated that the instrument concept will advance a complete
line of imaging spectrometers for the short- to long-wave mid-IR
regions at moderate to high spectral resolution and useful image
resolution, with real-time (video) image acquisition.
The new approach is based on a radiation tolerant advancement by
the University of New Mexico,which is used in this commercial program.
Integrating circuits with these sensors will allow drift cancellation,
exceptional miniaturization, and digital output. The goal of Phase I is
to prove that micromachining can produce sensors and sensor systems with
the performance required for space science. Complete mechanical sensor
and electrical circuit design plus mechanical structure prototypes will
verify feasibility and allow rapid fabrication of functional devices in
Phase II.
As part of a separate effort, the PI has developed the Integrated Payload (IP) concept for science missions to decrease integration cost and total payload resource requirements. This IP concept provides a single interface to the spacecraft, standard interfaces to sensors, conditioned power, functional partitioning of software, and a multiprocessor switched architecture. With all sensor data in a central processor and software constructs which allow sensors to control other sensors, the IP is an ideal platform for EEMOS.
Design_Net Engineering and the CSGC propose to combine these technologies creating the Integrated Payload Operations System (IPOS) which will simplify and lower the costs of payload development, integration and operations for a range of NASA, commercial, and DoD missions.
1) The Hierarchical Generalized Voronoi Graph (HGVG) approach to three dimensional motion planning that has been developed by Professor Howie Choset of Carnegie Mellon University; and
2) an intelligent robotic control architecture developed by
Metrica researchers. The first line of research will provide
a method for planning paths and for planning inspection
patterns in three-dimensional environments. When integrated
with the second line of research, a robust navigation ability
for free-flying robots in three-dimensional environments will
be achieved. In addition, the HGVG representation also
provides for planning a search pattern that guarantees complete
coverage. The resulting system will have many applications
within NASA and in the private sector.
Using the OW solar energy system, PSI has successfully demonstrated
plant growing in an enclosed plant growth chamber with solar light
delivered via 10-m long optical fiber cables. In the same study
PSI showed that solar radiation can be separated into two components:
plant growing spectra and non-plant growing spectra, and that only
the plant growing portion was delivered to the plant growth chamber.
The two technologies resident at UA and PSI can be effectively
combined for development of the solar plant lighting system for
life support in space.
Other potential commercialization areas include providing testing to airline crews, transportation firms, companies requiring night shift workers, and medical institutions where knowledge of key physiological parameters and control over circadian phases are crucial to overall performance and accuracy.
Liquid over-feeding was developed by the Oak Ridge National
Laboratory and was extensively tested on off-the-shelf air
conditioners. The test results showed a 12% improvement in
cooling capacity and 7.5% increase in system coefficient of
performance. Passive charging optimization technology (patent
pending at ORNL) would further improve the performance of the
advanced heat pump at off-design conditions. The objectives of
this research are the development of a computer model for
advanced heat pumps to be used in spacecraft, and development of
a prototype advanced heat pump unit.

Carbon aerogels are a special class of low density, open cell foams that
have high porosity (>90%), ultrafine pore sizes (<50 nm), high internal
surface area (400-1000 m2/g) and a solid matrix composed of
interconnected fibrous chains with characteristic diameters of 10 nm.
Carbon aerogels have demonstrated thermal stability at temperatures in
excess of 3000o C (>5432o F). Room temperature thermal conductivity of
carbon aerogels indicate a factor of fivefold less thermal conduction
when compared to other carbon foams of similar density. MER Corporation,
a small business, teamed with Southern Research Institute, a non-profit
research institution, proposes to perform the necessary research and
material property evaluations to develop a new generation of affordable,
low thermal conductivity thermal protection system (TPS) based on carbon
aerogel materials. A Phase I experimental effort is identified which
includes a preliminary materials synthesis and ultra- high temperature
materials characterization, and thermal analog demonstration of a carbon
aerogel subelement TPS.
This project proposes to combine new advances in tracking and
prediction of severe weather at the National Center for Atmospheric
Research with existing aircraft trajectory modeling software and
conflict detection and resolution algorithms to create a decision
support system for GA pilots. In Phase I, feasibility will be examined
by determining the accuracy and efficiency of convective-weather-
avoidance advisory information. If successful, Phase II will focus on
development of a demonstration system and execution of field trials to
evaluate system utility and refine human-computer interfaces. Existing
NCAR software will be used to ensure that improvements in prediction
accuracy and future icing-hazard products can be incorporated.
NASTEC, Inc. has extensive bearing design experience and will join the Wave Bearing inventor to apply this design to general aviation engines. Assisted by computer codes developed at the University of Toledo, the proposed phase I program will adapt the Wave Bearing to the design requirements of general aviation gas turbine engine. A test rig will be designed to the point of initiating manufacturing drawings in Phase I.
In Phase II, the design and fabrication of the test bearings and test
rig will be completed and the bearing will be experimentally validated.
NASA LeRC will provide facilities and test support for the Phase II
effort. The Army will also provide technical support.
In this age of focused environmental concerns, the use of Wave Bearings should lead to enhanced environmental efficiencies.
The project objective is to demonstrate the feasibility, in Phase I, of a design for a control
and display system that incorporates spoiler/throttle control and flight path displays that are engineered to facilitate the human machine interface to simplify the approach, flare, and landing phase of flight. The effort proposed for Phase I will provide the basis for the development of an integrated spoiler/throttle control and flight path display in Phase II and for the certification and commercialization of the system in Phase III as an integral element of the Global Aircraft Corporation's production airplane.
It is imperative, therefore, that an affordable and effective engine exhaust muffler be design, fabricated, evaluated, and commercialized. This muffler must significantly reduce engine exhaust noise with minimal effect on engine performance.
Embry-Riddle Aeronautical University (ERAU) possesses significant expertise in aircraft acoustics, design and evaluation as well as prototype manufacturing capabilities and appropriate testing facilities. These capabilities will be used to implement the necessary technology transfer to Global Aircraft Company to produce an effective, small, light weight, safe and affordable GA muffler exhaust system.
The injectors will become a critical subsystem for the PDREs being
developed by Adroit Systems, Inc. (ASI). The developed injectors would
ensure good mixing and atomization in conjunction with the highly
transient filling process of PDRE combustion chambers, resulting in an
innovative and precise mixing and atomization technology for cryogenic
fluid delivery. The Department of Mechanical Engineering Department of
the Pennsylvania State University (PSU) has broad experience in a wide
spectrum of injector designs, and in addition, has appropriate injector
design technology that is applicable to the proposed effort. This joint
teaming of University capability and small business expertise therefore
would ideally match the intent and spirit of the STTR program.
Sanders Design International (SDI) is the creator of the Model Maker Ink Jet Rapid Prototyping (RP) Technology. The University of Michigan has demonstrated the ability to create rapid prototypes made from ceramics using the 3D Systems SLA process. Working with the University of Michigan, SDI has performed initial testing of ceramic filled resins
that have rheology suitable for jetting. These experimental results
provide us the confidence that we will be able to jet ceramic powders in an advanced Model Maker System. Combining the University of Michigan technology with advances in the jet head design of the Model Maker will allow an Ultra-Precision Model Maker (UPMM) to be developed under the proposed program.
The Phase I objective is to establish and demonstrate the feasibility of developing a modular framework system capable of interfacing and integrating the multiple computer based modeling, simulation and analysis systems presently being applied to RBCC ETO vehicle development. The objective of Phase II will be to provide a working system ready for commercialization in Phase III.
The effort consists of further evolving GIT's "IMAGE" modular framework system to interface and integrate existing industry "standard" RBCC ETO vehicle/propulsion design and performance analysis models. The framework system will be extended to incorporate the modified GIT cost module to demonstrate cost based on an activity based economic methodology.
The results will be a prototype of an expandable, modular framework
system capable of supporting multi-disciplinary design/cost optimization
and being extensible to the remaining phases of the full life-cycle of
RBCC engine propelled ETO vehicles and the general problem of the
development of complex technological systems in the industrial, utility
and commercial marketplaces.
This proposed system with the enhanced IMAGE and activity based cost model, will be applicable to not only airbreathing and rocket based vehicles and engines, but any aircraft or spacecraft system; in general the proposed methodology is applicable to any complex system. At the present time, the commercial need for the proposed system and activity based cost model is expanding for the government, military and commercial entities is at hand. The proposed products provide for commercial spin-offs in the following technology areas: graphic modeling in simulated real-time, Internet application for graphical inventory techniques applied to cost model, Internet collaborative research capabilities, post-flight data bases and analysis techniques, configuration management, multi-disciplinary design optimization and system modeling.
Phase-I objective is to produce a feasibility prototype of the simple
modular framework with integrated analysis and cost modules. Phase-II
provides a working system capable of Phase-III commercialization.
Phase-I effort consists of developing ISSI's modular framework system
and integrating/interfacing the modified PSU ejector scramjet RBCC
engine code, activity based cost module and component library, and other
codes (trajectory: POST and DOF36, aerodynamics: APAS, weights and
sizing: CONSIZ, CAD: ProENGINEER) resulting in a prototype of integrated
and expandable RBCC system to support design, performance, and cost
analyses. A feasibility demonstration will be conducted.
There are approximately 40 accelerators in the U.S. and 1500 worldwide, which use superconducting magnets and cavities that require temperature monitoring in presence of electromagnetic fields.
Magnetic resonance imaging (MRI) systems used in hospitals and industrial applications require superconducting magnets. Temperature monitoring using the proposed method will be most suitable.
Magnetic levitation rail systems where cryogenic cooling is required will need continuous temperature monitoring. Magneto-hydrodynamic (MHD) power generation and propulsion systems employ superconducting coils which require temperature monitoring.
Superconducting magnets required for tokamaks and inertial confinement systems can use the proposed temperature sensor.
