A supersonic compressor rotor includes a rotor disk (48) comprising an upstream surface (60), a downstream surface (62), and a radially outer surface (58) that extends between the upstream surface and the downstream surface, the radially outer surface including an inlet surface (148), an outlet surface (150), and a transition surface (152) extending between the inlet surface and the outlet surface, the rotor disk defining a centerline axis (54), a plurality of vanes (46) coupled to the radially outer surface, adjacent the vanes forming a pair and oriented such that a flow channel (86) is defined between each the pair of adjacent vanes, the flow channel extending between an inlet opening and an outlet opening, the inlet surface defining an inlet plane (154) extending between the inlet opening and the transition surface, the outlet surface defining an outlet plane (156) extending between the outlet opening and the transition surface that is not parallel to the inlet plane, and at least one supersonic compression ramp (110) positioned within the flow channel to facilitate forming at least one compression wave (112) within the flow channel.
