| Abstract: | The recent developments of transonic and supersonic compressor over the world are briefly reviewed and discussed. The roles of various stages are clearly represented on an efficiency versus pressure ratio diagram and also on a normal shock compression efficiency and work coefficient versus Mach number reference diagram. The traditional diffusion factor Dserves as a rough guide only and new criteria or coefficients are needed to reflect supersonic cascade losses more nearly. Further developments from pressure ratio 2:1 upward with efficiency higher than 85% are prospective. Comparative research of stages with positive, zero and negative prewhirls is proposed. Importance of studying physical mechanism and measures to improve surge margin is finally stressed. |
