Abstract

A gas compressor (20) based on the use of a driven rotor (30, 32) having a compression ramp (R) traveling at a local supersonic inlet velocity (based on the combination of inlet gas velocity and tangential speed of the ramp) which compresses inlet gas against a stationary sidewall (42, 44). 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 rim of the rotor (30, 32), the strakes (S), and a stationary external housing (22). Part load efficiency is enhanced by the use of a pre-swirl compressor (104, 106), and using a bypass stream to bleed a portion of the intermediate pressure gas after passing through the pre-swirl compressor back to the inlet of the pre-swirl compressor.
