摘要/Abstract

摘要： 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。

Abstract: An application of dynamic compression system model to the transonic axial flowcompressors is presented. The dynamic response of two transonic axial flow compressors to abruptchanges of inlet temperature or pressure-temperature combinatinon has been calculated based on stageby-stage compressor characteristics. A new method of recognition of predicting aerodynamic stabilityis established by using dynamic airflow variations. The calculated results are in good agreement withavailable experimental data. It has been found that the effects of abrupt inlet pressure on compressorstability should be taken into account.
