Abstract : The predominant requirements on small jet-engines are high power-to-weight ratio and low specific fuel consumption in combination with structural simplicity. The consequent demands on the compressor can be fulfilled either by a conventional two-stage unit or by an extremely loaded single stage. This single stage compressors has to be able to perform a sufficiently large mass flow and total pressure ratio. Consequently the application of a mixed-flow compressor with supersonic flow at rotor- and stator-inlet (supersonic mixed-flow compressor) turns out to be advantageous. The conception of a jet-engine with a supersonic compressor demonstrates the significantly reduced sized compared to other engines of the same thrust class.
