摘　　要：以某型高压压气机为试验对象,研究了进口总压180°周向畸变对该压气机性能的影响。开展进口均匀进气和总压周向畸变条件下的压气机特性录取试验,并对试验结果进行了对比分析。结果表明:进气周向畸变导致压气机性能恶化,流量、效率均有一定程度的下降;周向畸变对高转速影响较大,随着转速降低影响逐渐减弱。A ten-stage axial high pressure compressor has been tested to investigate the influence of inlet total pressure 180°circumferential distortion on compressor performance.Experiments were performed with uniform and distortion inlet pressure conditions to measure compressor characteristics.Test results were analyzed and compared.Results indicate that inlet pressure distortion shows adverse effects on compressor performance,that both mass flow and efficiency were reduced.In addition,the compressor performance deterioration increases with increasing compressor operating speed.
