Claim:
1. A supersonic compressor rotor comprising: a first rotor disk; a second rotor disk; a first set of rotor vanes coupled to and disposed between the first and the second rotor disks and defining together with the first and the second rotor disks, a first set of radial flow channels; a second set of rotor vanes coupled to and disposed between the first and the second rotor disks and defining together with the first and the second rotor disks, a second set of radial flow channels, wherein the first set of rotor vanes is disposed offset from the second set of rotor vanes, wherein the first set of radial flow channels and the second set of radial flow channels are configured such that each flow channel of the first set of radial flow channels is in fluid communication with at least one flow channel of the second set of radial flow channels a plurality of compression ramps located in each of the first and second flow channels configured such that each compression ramp is disposed on a rotor vane surface opposite an adjacent rotor vane surface; and, wherein each flow channel of the first set of radial flow channels comprises a first cross-sectional area proximate to an end of each compression ramp located in the first flow channel, wherein each flow channel of the second set of radial flow channels comprises a second cross-sectional area proximate an end of each compression ramp located in the second flow channel, and wherein the second cross-sectional area is smaller than the first cross-sectional area.
