This article covers the analysis and study of the surge characteristic in a full-scale 10-stage subsonic compressor under the condition of performance test. The transient responses which arised after the compressor en ters in non-stationary condition range are estimated through an improved nonlinear calculation model. There are two different kinds of response (or transient nrocesse ) model: stall pattern and surge pattern. The calculated results coincide with the test very well. When relative

The obtainted calculation result has been drawn as a system transient process locus in the nondimensional flow-pressure rise phase plane. The nondimensional parameters affecting system transient process pattern were analysed and compared with the results made by E.Y. Greitzer.
