Abstract: A compressor (20) has an inlet (24). An outlet (26) is downstream of the inlet along a flowpath when the compressor is in a first operational condition. A centrifugal impeller (28) is mounted for rotation about an impeller axis. A supersonic rotor (30) is mounted for rotation about a rotor axis and configured to rotate opposite the impeller and tangentially compress in the first operational condition.
