中文摘要：
回顾和总结了关于弯叶片在压气机中气动机理的不同理解。深入探讨了压气机中弯叶片叶栅的气动力学变化,给出了弯叶片气动机理的另一种解释,即弯叶片在亚音速叶栅中通过改变密流的径向分布控制分离流动的发展,在超跨音速叶栅中通过改变激波前后的压力分布控制激波强度的大小。
英文摘要：
Several viewpoints about aerodynamics mechanism of bowed blade in diffusion cascade were recalled and summarized.A further study on aerodynamics action of bowed blade in a compressor was achieved and a new explanation was presented.The explanation was bowed blade controlled separation evolution by changing the radial distribution of axial velocity-density in subsonic cascade and controlled shock intensity by changing the pressure distribution forward(backward)shock in transonic cascade.
