摘　　要：在多级轴流压气机特性计算HARIKA算法基础上,发展了一种预测多级轴流压气机率先失速级的方法。该方法结合多级轴流压气机单级的最大静压升能力和实际工作点的特性,配合使用单级级叠加非设计点性能预测方法,可以很好地预估多级压气机的率先失速级,与已有试验结果比较表明该预测方法是正确可靠的。Based on the HARIKA arithmetic used to caculate muff-stage axial compressor performance, a method to predict the rotating stall stage in multi-stage axial flow compressor is developed. The method relate the maximum static-pressure-rise capability of a mutistage compressor stage with the characteristic of operating point , with reference to the off-design prediction method of single-stage iteration , the rotating stall stage can be predicted sucessfully. The method is correct and robust for good agreements between the predictions and experiment results indicted.
