国外斜流压气机设计技术的发展

Development of foreign diagonal flow compressor design technology

斜流压气机兼有离心压气机高压比,工作范围广和轴流压气机流量大、高效率、迎风面积小的特点,在未来小推力级军用涡扇、高功重比军用/民用涡轴发动机上具有广阔的应用前景。必须尽快开展高负荷高效率斜流压气机设计与试验技术的研究。文章通过国外斜流压气机设计技术发展的回顾,总结了其技术特点和关键技术难点,展望了未来斜流压气机设计技术发展的新机遇。

In order to learn to the advanced design experience on the medium and small aircraft engine compressorin Europe, the U.S. and other countries, in this paper, through the technical review of the development of foreign diagonal flow compressor design, and summarized the technical characteristics and the key technical difficulties, looked to new opportunities of the future diagonal flow compressor design technology development opportunies.
