Abstract:
1. A supersonic compressor rotor comprising: (a) a first rotor disk; (b) a second rotor disk; and (c) a third rotor disk; said first, second, and third rotor disks sharing a common axis of rotation; said first and second rotor disks being rotatably coupled and together defining a rotor surface of the supersonic compressor rotor; said third rotor disk being disposed between said first and second rotor disks, said third rotor disk being independently rotatable relative to said first and second rotor disks, said third rotor disk comprising a raised surface structure; said first, second and third rotor disks together with at least two vanes defining a flow channel encompassing the raised surface structure of the third rotor disk; said flow channel comprising a supersonic compression ramp; wherein the at least two vanes are disposed in a screw-like fashion across the rotor surface defined by the first and second rotor disks and rotatably couple the first and second rotor disks, and wherein the raised surface structure is of dimensions such that it may not pass under a vane.
