摘要
基于轴流压气机叶排特性,建立了一种预测周向总压畸变沿轴流压气机传递的矩阵分析模型,应用于某一单级压气机,对其进口总压畸变传递特性进行了详细的数值分析,给出了对发动机稳定性分析中影响较大的总压、总温及气流角的周向分布。计算结果与实验结果比较表明,本模型和采用的方法合理,可行。
A new model was established for the prediction of the decay of circumferential pressure distortion in multistage axial flow compressors. An efficient calculation procedure was developed which could be used to predict the propagation of the total pressure, temperature and velocity distortion through axial flow compressors. The validity of this model was demonstrated by comparing the numerical results with experimental data. Based on the model given, suggestions can be made for the design of distortion-tolerant axial flow compressors.
