According to the definition of the three-dimensional swept leading edge,a comparison was made between three different swept transonic rotors to study how different leading edges affect the position and intensity of shock waves,and consequently the performance of fans.

本文从叶片前缘曲线掠的形式入手,采用适合叶轮机械内三维流动特点的相对掠概念,把叶片前缘曲线相对掠应用到设计中,探讨叶片前缘曲线相对掠(包括相对前掠、相对无掠和相对后掠)对通道激波的方位、强度的影响,以及由此造成的对风扇性能的影响,并进行了数值模拟,从得到的结果可以看出转子前缘曲线对风扇/压气机的性能影响非常明显,并对设计在气动方面的优化有一定的指导作
