  • A series of relevant experiments were carried out for assessing high-pressure compressor distortion characteristics accurately. Inlet pressure distortion experiment methods of high-pressure compressor were emphasized, and targets of characteristic parameters such as complex distortion index, dynamic and steady state distortion components, threshold value, distortion contours as well as test concept and experimental data processing method were proposed. Furthermore, as the inlet pressure distortion experiment for a kind of high-pressure compressor was accomplished, and the effect on the performance of this high-pressure compressor by total pressure distortion along with the assessment data for relative stability was obtained. Experiment results show that high-pressure compressor has significantly higher pressure distortion sensitive coefficient, weaker anti-distortion ability than fans under off-design speed; high-pressure compressor is identical with fan in pressure distortion sensitive coefficient under design speed, showing strong anti-distortion ability and aerodynamic stability.
