Pulsating pressure measuring points are usually arranged at the compressor outlet to detect surge. In this paper, for a five-stage high-pressure compressor, the pulsating pressure signals at different circumferential positions of each stage are collected the characteristics of stall and surge signals are comprehensively analyzed, to lay a foundation for the exploration of stall prediction methods.
