Abstract
Surge is one of the most serious faults in aero-engine compressor.Effective monitoring of surge ensures the flight safety of airplane.This paper presents a new method for monitoring of aero-engine compressor surge based on critical B parameter. Based on the Moore-Greitzer incompressible compressor model,the stability of the compression system is analyzed in this paper. Furthermore,the critical B parameter expression is derived by the bifurcation theory.Finally,the whole state Bcr surface figure is obtained and the unstable behavior of the compressor in the operation state can be real-time monitored and predicted.关键词
