Cascade optimization strategy for aircraft and air-breathing propulsion system concepts

Flight optimization system (FLOPS) and the NASA engine performance program analyzer (NEPP) used in the design optimization for aircraft and air-breathing propulsion engine concepts. The FLOPS code was incorporated into the code COMETBOARDS which successfully solved both subsonic and supersonic aircraft problems. Also, NEPP and COMETBOARDS in combination successfully optimized a number of subsonic and supersonic engine design. Aircrafts and engines includes cascade optimizing strategy, constraint and design formulations, and global scaling strategy as the key features and unique strengths of COMETBOARDS.
