| 摘 要： | 基于逐级平行压缩系统模型，发展了一种分析周向组合畸变对多级轴流压缩系统稳定性影响的通用分析方法。应用此方法对两个多级轴流压气机进行了详细的数值分析，给出了纯压力畸变、纯温度畸变及压力－温度不同位置的组合畸变与轴流压气机喘振裕度损失之间的定量关系。

| Abstract: | A general numerical method is developed for predicting aerodynamic stability inmultistage axial compression systems with inlet combined pressure and temperature distortion basedon stage-by-stage parallel compression system model. The predictions for two multistage axial flowcompressors are given by using this method. The quantitative relationships between the inlet totalpressure distortion, or total temperature distortion, or combined pressure and temperature distortionand the surge margin losses are obtained. It is found that the effects of aligned pressure andtemperature distortion on aerodynamic stability of axial compressors are the most strong. |
