Next generation General Aviation (GA) Sport Class air vehicles limited to 1200lbs, represent the first opportunity to overhaul the FAA certification process necessary to manufacture affordable aircraft. With propulsion representing over one-third of the direct manufacturing costs of the entire aircraft, dramatic reductions in aircraft engine costs must be achieved by design, economy of scale, and ...

The proposed PAVE propulsion system technology demonstration combines an innovative high-speed aero-diesel engine with a novel ducted fan assembly resulting in a low noise/cost and high performance propulsion system. The core engine makes extensive use of a novel self-injection, compression ignition/combustion system capable of high-speed operation on kerosene-based fuels without degradation due t ...

Sierra Engineering Inc. (Sierra) believes that the subject triaxial liquid propellant swirl injector has the potential to meet many of NASA's Earth-to-Orbit (ETO) propulsion systems goals. The triaxial swirl injector is ideally suited to a wide range of liquid oxidizers and fuels, including hydrogen and a variety of hydrocarbons. It holds the potential of excellent high-frequency combustion stabi ...

The pace and cost of developing an engine system for future explorations is strongly influenced by the inadequacies of design tools and the supporting databases. The inability to predict the internal operating environments of a combustion chamber during the design process necessitates design iterations during the development process. NASA and the Department of Defense are working to increase the ...

This proposal discusses the development and application of new methods of structural-acoustic analysis in order to address existing problems in aircraft interior noise prediction. The proposed methods are based on a hybrid modeling strategy that combines Finite Element Analysis (FEA) and Statistical Energy Analysis (SEA). Over the past five years, Vibro-Acoustic Sciences has devoted a considerab ...

MANNED LUNAR BASES WILL REQUIRE COOLING FOR DEHUMIDIFICATION(ABOUT 40 DEGREES FAHRENHEIT) AND HABITAT (60 DEGREES FAHRENHEIT). THE BACKGROUND TEMPERATURE FOR HEAT REJECTION IS 125 DEGREES FAHRENHEIT, REQUIRING REJECT TEMPERATURES OF 180 DEGREES FAHRENHEIT OR ABOVE. WASTE HEAT WILL BE AVAILABLE FROM THE POWER-GENERATING SYSTEM ABOVE 500K (440 DEGREES FAHRENHEIT). COMPLEX-COMPOUND SORPTION CYCLES CA ...

THE DESIGN OF A NOVEL OPEN CAVITY ANTI-RESONANCE TECHNIQUE WILL BE CARRIED OUT UNDER THE INITIAL PORTIONS OF THE PHASE I EFFORT. DETAILED DESIGN AND FABRICATION OF THE AIRCRAFT MODIFICATIONS TO BE PERFORMED ON THE KUIPER AIRBORNE OBSERVATORY WILL BE CARRIED OUT BY THE GOVERNMENT. THE CONTRACTOR WILL PERFORM A FULL-SCALE FLIGHT EXPERIMENT USINGTHE INNOVATIVE SHEAR LAYER CONTROL FAIRING IN CONJUNCTI ...
