초록

An axial supersonic compressor comprises a casing and a hub rotating in the casing and carrying blades. The suction surface of each blade is formed with a zone in which the curvative changes and which corresponds to a supersonic-subsonic shock wave. A channel formed in each blade and opening in said zone is connected to boundary layer aspiration means.

청구항

In a rotary supersonic compressor comrising a casing having an axis, a rotor mounted for rotation about said axis and having a hub carrying a first set of blades spaced from said axis, regularly distributed about said axis and defining axial passages for a gaseous fluid to be compressed, a second set of blades carried by said casing,, spaced from said axis, regularly distributed about said axis and defining axial passages receiving fluid from the passages of said rotor, said rotor being arranged to be driven in operation at a speed sufficient for the gas...
