旋转进气畸变对轴流压气机气动稳定性影响实验研究
Effects of Rotating Inlet Distortion on a 5-Stage HP-Compressor Stability
-
摘要: 利用RB-1995级高压压气机,实验研究了进口旋转总压畸变对其性能和气动稳定性的影响,获得了总压畸变的旋转频率对高压压气机喘振裕度损失的影响结果。结果表明:正转时,减少了压气机的喘振裕度,并且存在2个危险频率,出现损失峰值;反转时,对喘振裕度影响较小,甚至提高了压气机的喘振裕度。Abstract: The inlet flow rotating distortion effects in a five-stage HP compressor have been investigated experimentally。For co-rotating distortions,the results exhibited significant loss in stability margin and there were two peaks in surge margin degradation corresponding to two distortion rotating frequencies;For counter rotational distortions,the tests showed minimal loss of stability margin,especially in some cases.The range of stable operations was even enlarged.
