Vane design method for starting transient performance optimization and vane pump designed through vane design method

The invention discloses a vane design method for starting transient performance optimization and a vane pump designed by the vane design method for starting transient performance optimization, in the vane design method for starting transient performance optimization, a vane is provided with a vane inlet edge and a vane outlet edge, and the vane is constructed to have different attack angles at any point on the vane inlet edge. According to the blade design method for starting transient performance optimization, through design of the attack angle on the blade inlet edge, the blade inlet loss can be effectively reduced, and the pressure distribution of the blade inlet edge can be optimized, so that flow separation is inhibited, the stable flow at the end of starting is increased, and the starting transient performance is improved. 本发明公开了一种启动瞬态性能优化的叶片设计方法及其设计的叶片泵，启动瞬态性能优化的叶片设计方法中，所述叶片具有叶片进口边和叶片出口边，所述叶片被构造为在所述叶片进口边上任意一点的冲角的大小不相同。根据本发明实施例的启动瞬态性能优化的叶片设计方法，通过对叶片进口边上冲角的设计，可以有效减小叶片进口损失，优化叶片进口边的压力分布，从而抑制流动分离，增大启动结束时的稳定
