TBCC Fan Stage Operability and Performance
Author(s): Suder, Kenneth L.
Abstract: NASA s Fundamental Aeronautics Program is investigating turbine-based propulsion systems for access to space because it provides the potential for aircraft-like, space-launch operations that may significantly reduce launch ...

Document ID: 20080047340
The effect of adding roughness and thickness to a transonic axial compressor rotor
Author(s): Suder, Kenneth L.; Chima, Rodrick V.; Strazisar, Anthony J.; Roberts, William B.
Abstract: The performance deterioration of a high speed axial compressor rotor due to surface roughness and airfoil thickness variations is reported. A 0.025 mm (0.001 in.) thick rough coating with a surface finish of 2.54-3.18 RMS ...

Publication Year: 1995
Added to NTRS: 2008-11-10
Accession Number: 95N30524; Document ID: 19950024103; Report Number: E-9709, NAS 1.15:106958, NASA-TM-106958
Effect of Variable Chord Length on Transonic Axial Rotor Performance Investigated
Author(s): Suder, Kenneth L.
Abstract: During the life of any gas turbine, blade erosion is present, especially for those units that are exposed to unfiltered air, such as aviation turbofan engines. The effect of this erosion is to reduce the blade chord ...

Active Control of Rotating Stall Demonstrated for a Multistage Compressor With Inlet Distortion
Author(s): VanSchalkwyk, Christian; Bright, Michelle M.; Suder, Kenneth L.; Straziar, Anthony J.; Thorp, Scott A.
Abstract: Aircraft compressors can suffer debilitating consequences as a result of rotating stall and surge events caused by inlet distortions. This is particularly true of aircraft during takeoff, when the compressor is operating at ...

Compressor Stability Enhancement Using Discrete Tip Injection
Author(s): Suder, Kenneth L.; Hathaway, Michael D.; Thorp, Scott A.; Strazisar, Anthony J.; Bright, Michelle B.
Abstract: Mass injection upstream of the tip of a high-speed axial compressor rotor is a stability enhancement approach known to be effective in suppressing small in tip-critical rotors. This process is examined in a transonic axial ...

Design and performance of controlled-diffusion stator compared with original double-circular-arc stator
Author(s): Gelder, Thomas F.; Schmidt, James F.; Suder, Kenneth L.; Hathaway, Michael D.
Abstract: The capabilities of two stators, one with controlled-diffusion (CD) blade sections and one with double-circular-arc (DCA) blade sections, were compared. A CD stator was designed and tested that had the same chord length but ...
