基于逐级压缩系统模型，发展了一种动态压力畸变下压缩系统失稳识别的数值预测方法。应用方法对一多级轴流压缩系统进行了数值分析。给出了动态压力脉动频率与压缩系统失稳首发级及不稳定发生时间之间的定量关联关系。
Based on the system model of stage-by-stage compression, a numerical method for predicting the instability of compression system under dynamic pressure distortion is developed. A numerical analysis of a multi-stage axial compression system is carried out. The quantitative relationship between the dynamic pressure pulsation frequency and the onset and instability of the compression system is given.
