General Aviation Propulsion Program Diesel Engine Mockup:
This Teledyne Continental Motors engine mockup was on display at Experimental
Aircraft Association's Oshkosh '97 Fly-In Convention. It is being developed for
NASA's General Aviation Propulsion Program. The engine is a horizontally
opposed, two stroke, compression ignition (Diesel) engine which will run on
jet fuel. Jet fuel is much more available world wide than gasoline and is
much cheaper than gasoline in some areas. The demonstrator engine will be a
4-cylinder, 200 horsepower engine.

General Aviation Propulsion Program Turbine Engine Demonstrator Aircraft:
This is the Williams International V-Jet II aircraft, conceptually designed by
Dr Sam Williams with final design and manufacture performed by Scaled
Composites. It will be powered by the FJX-2 turbine engine being developed by
Williams International as part of the NASA General Aviation Propulsion Program.

Imagine flying a commercial airliner from California to
Japan in only four hours. NASA's High Speed Research Program is
working to make this a reality. NASA's programs maintain U.S. industry's
strength in high speed aeronautics through technologies that will enable the
building of an environmentally compatible and economically viable High Speed
Civil Transport. High Speed Research will reduce stratospheric emissions,
airport noise, sonic booms, and manufacturing costs while increasing the range
and payload capabilities of high speed aircraft.

The Advanced Concepts Program was created to establish an opportunity to coalesce NASA, industry, and university
capabilities and develop aeronautical concepts that have high technical risks and high potential benefits for U.S. industry. As
part of the Advanced Concepts Program, the Blended-Wing-Body Technology Study is a 3-year technology development
program to assess the technical and commercial viability of an advanced, unconventional aircraft configuration.

APNASA, the Average Passage Code, is a computer code which uses a parallel
computer system. NASA currently has a collaborative arrangement with General
Electric to use the APNASA code to perform an analysis of the GE90 turbofan,
shown here. The goal is to perform an analysis of the primary flowpath of the
engine, at the design point operating conditions in under 24 hours of central
processing unit (CPU) time on a parallel computer system. The primary flowpath
of the GE90 turbofan consists of a nacelle and inlet, many blade rows of
turbomachinery (the fan and compressor), a combustor and an exhaust nozzle.

This delta-winged aircraft will carry 300 passengers to the Pacific rim at cruise
speeds of Mach 2.4.

Trailblazer is a Rocket Based Combined Cycle
spacecraft concept under investigation at the NASA Glenn Research
Center. The program goals are two-fold: to develop and demonstrate
Airbreathing Launch Vehicle technologies for the 21st century. These
technologies will pave the way for a dramatic cost reduction of access
to space using Single Stage to Orbit spacecraft.

Leading the world in flight - in the air as well as in
space - has a profound impact on our nation, socially, economically, and
politically. Unbelievable discoveries are right over the horizon, but to
achieve them requires an ambitious view of the future and a willingness to
take risks. As NASA Administrator Dan Goldin has stated, our responsibilty
to the American public is to ensure that NASA's work in science and technology
sustains U.S. leadership in civil aeronautics and space.

Shown here is a hot gas ingestion test at the NASA Glenn Research Center.
In this experiment, the hot jet exhaust gases that circulate around
and re-enter the engine are studied for the case of a vertical takeoff fighter aircraft.

The objectives of the Advanced Subsonic Technology (AST) program are to enable the
production of a new generation of superior U.S. subsonic
aircraft and engines that are fuel efficient and
environmentally compatible with superior cost,
convenience, and safety.
The AST Program works with industry to recapture
market share, maintain the balance of trade, and increase U.S. jobs.
