View the Complete Application at the US Patent & Trademark Office
A stator. The stator may be used in a supersonic compressor that utilizes a rotor to deliver a gas at supersonic conditions to the stator. The stator includes a plurality of aerodynamic ducts that have converging and diverging portions, for deceleration of gas to subsonic conditions and then for expansion of subsonic gas, to change kinetic energy of the gas to static pressure. The aerodynamic ducts include structures for changing the effective contraction ratio to enable starting even when the aerodynamic ducts are designed for high pressure ratios, and structures for boundary layer control.
