TRANSIENT BEHAVIOR SENSITIVITY ANALYSIS OF AIRCRAFT ENGINES

MANUEUVERABILITY AND SAFETY OF AIRCRAFT, SPECIALLY MILITARY PLANES HIGHLY DEPEND ON TRANSIENT POWER RESPONSE OF THEIR PROPULSION ENGINES. THE RATE AND LEVEL OF ENGINE RESPONSE WILL DEPEND ON MANY PARAMETERS INCLUDING ENGINE TYPE, ITS INTERNAL DESIGN CHARACTERISTICS AND ITS OPERATIONAL CONDITIONS. THIS PROPOSAL PRESENTS A RESEARCH APPROACH AND PLAN FOR IDENTIFICATION OF THE PARAMETERS WHICH HAVE NOTICEABLE EFFECT ON THE TRANSIENT POWER RESPONSE OF VARIOUS AIRCRAFT TURBO-ENGINES, MODELING THE COMPONENTS AND THE ENGINES, AND DEVELOPMENT OF A COMPUTER SOFTWARE TO SIMULATE THE TRANSIENT OPERATION OF THESE ENGINES. THE SPECIFIC APPLICATION OF THE DEVELOPED SOFTWARE WILL BE IN SENSITIVITY ANALYSIS OF THE TRANSIENT BEHAVIOR OF THESE ENGINES WITH RESPECT TO THEIR KEY DESIGN AND OPERATIONAL PARAMETERS. THE SOFTWARE WILL BE DESIGNED TO INTERFACE WITH U.S. NAVY ENGINE SIMULATORS.
