【摘要】 <正> 一、前言 透平的弯扭联合成型叶片在国外已发展到实用阶段,但这种叶片应用在压气机中是否合适,国内外有关研究资料甚少,在有限的几篇研究报告中所得结论并不完全一致。有些实验表明,在压气机中采用弯曲叶片的效果是比较显著的。美国的G·E公司在其先进的E~3发动机设计中已采用了这一先进技术。为了弄清压气机在什么条件下采用弯曲叶片最佳,本文首先对弯曲叶片中流动机理进行较深入分析,通过一些具体算例,探讨了压气机中采用弯曲叶片的优越性。更多还原

【Abstract】 Mechanism of bowed blade is studed in this paper. A design system for compressor with sweep and dihedral blades is presented. The computer programm employing this design system has been performed and has been used to calculate an example. The computed results are compared with E3 engine’s data, and good agreement is shown. The conclusion is that the application of bowed blade to compressor is beneficial to reducing secondary losses.更多还原
