Provided is a supersonic compressor having a supersonic compressor rotor including a clockable rotor disk allowing restriction or opening of portions of a fluid flow channel of the rotor in order to enhance performance of the rotor during different operational stages, for example rotor start-up or steady state. The supersonic compressor has a first rotor disk, a second rotor disk and a third rotor disk which share a common axis of rotation. The first and second rotor disks are rotatably coupled, and the third rotor disk is disposed between them. The third rotor disk is independently rotatable relative to the first and second disks, and has a raised surface structure for restricting or opening a portion of the flow channel defined by the three rotor disks and at least two vanes. The flow channel contains a supersonic compression ramp and encompasses the raised surface structure.
