Patent ID: 8827640

Claim:
A supersonic compressor rotor comprising: a rotor disk comprising a substantially cylindrical endwall, a radially inner surface, and a radially outer surface, said endwall extending between said radially inner surface and said radially outer surface; a plurality of vanes coupled to said endwall, said vanes extending outwardly from said endwall, adjacent vanes forming a pair and are spaced a circumferential distance apart such that a flow channel is defined between each said pair of circumferentially-adjacent vanes, said flow channel extending generally radially between an inlet opening and an outlet opening; a first supersonic compression ramp coupled to said endwall, said first supersonic compression ramp positioned within said flow channel to facilitate forming at least one compression wave within said flow channel; a shroud assembly coupled to the vanes, the vanes extending between an inner surface of said shroud assembly and the endwall; and a second supersonic compression ramp coupled to the inner surface of the shroud assembly, the second compression ramp extending from the inner surface of the shroud assembly towards said endwall, the second supersonic compression ramp being positioned with respect to the first supersonic compression ramp such that a throat region is defined between the first supersonic compression ramp and the second supersonic compression ramp.
