摘　　要：基于公开发表的研究成果,完善了1种新的跨声速轴流压气机总压损失及落后角预测模型,并发展了相应的跨声速轴流压气机非设计性能分析方法,建立了相应的计算机模拟程序。对2个跨声速轴流压气机的设计及非设计性能进行了数值模拟,对所得计算结果与试验结果的比较表明,本模型与分析方法能够应用于工程计算。Based on the published research achievements, the total pressure loss and deviation angle predicting models of a new transonic axial flow compressor are improved, and the off - design performance analysis method of the corresponding transonic axial flow compressor is developed, and the corresponding computer simulation program is built. The numerical simulations of the design and off - design performance are performed in the transonic axial flow compressor. The comparison between calculation results and test results indicates that the model and analysis methods can be applied to engineering calculation.
