耦合对风扇、压气机畸变传递特性的影响
The Effect of Coupling on Distortion Transfer in Fan and Compressor
-
摘要: 本文从下游部件对具有畸变流动的压气机性能的影响机理出发, 着重分析了由于高压压气机的存在对具有进口压力畸变的风扇出口畸变强度的影响。采用一种新的快速收敛方法, 结合某型号发动机对耦合的影响进行了定量计算。Abstract: The mechanism of spool coupling effect on distortion transfer in fan and compressor is analyzed.A quick convergent method is selected to calculate amplitude of the total pressure distortion at exit of low pressure spool in cases of no coupling,complete coupling,and real coupling respectively,then the correcting coefficient of the distortion transfer is obtained.The results show that the distortion transfer characteristics of no coupling differ from those of actual coupling.
