a gas compressor based on the use of a driven rotor having an axially oriented compression ramp traveling at a local supersonic inlet velocity which forms a supersonic shockwave axially , between adjacent strakes . in using this method to compress inlet gas , the supersonic compressor efficiently achieves high compression ratios while utilizing a compact , stabilized gasdynamic flow path . operated at supersonic speeds , the inlet stabilizes an oblique / normal shock system in the gasdyanamic flow path formed between the gas compression ramp on a strake , the shock capture lip on the adjacent strake , and captures the resultant pressure within the stationary external housing while providing a diffuser downstream of the compression ramp .
