To determine the stability margin loss of aeroengine under measured pressure and temperature combined distortion in flight test, the stability margin loss evaluation method was studied based on equivalent conversion of distortion contour and parallel compressor model. The stability boundary of the compression system under distortion was obtained by equivalent coordinated conversion of the combined distortion contour and parallel compressor model calculation. Then the operating point of compression system was determined through the flight test data at the moment of distortion, and the stability margin loss can be calculated. For a stalled turbofan engine during flight test, the stability margin loss of the fan was 9.2% when the temperature non-uniformity was 2.2%, the circumferential total pressure distortion intensity was 3.3%, and the high-temperature and low-pressure regions were in phase. The results showed that the method can be used to determine the stability margin loss of aeroengine under pressure and temperature combined distortion measured in flight test.
