基于多级轴流压气机的逐级特性,详细研究了跨音多级轴流压气机对突变型温度扰动、突变型压力-温度联合扰动的动态响应和气动稳定性。同时还给出了动态扰动下多级轴流压气机失稳识别的新的预估方法。
Based on the step-by-step characteristics of multistage axial-flow compressor, the dynamic responses and the aerodynamic stability of the combined multistage axial-flow compressor to sudden temperature perturbation and sudden pressure-temperature perturbation are studied in detail. At the same time, a new method of estimating the instability of multi-stage axial-flow compressor under dynamic disturbances is also given.
