摘　　要：飞机一般采用S形进气道,针对S形进气道中流动分离较大的问题,采用内表面加装涡流发生器的方法减小旋流畸变。通过计算确认加装涡流发生器后进气道流动分离大大减弱,验证了涡流发生器的作用。Aircraft generally adopts snake inlet. Aiming at the problem of large flow separation in the snake inlet, the internal surface needs to add vortex generator to reduce the swirl distortion. It was confirmed by calculation that the flow separation in the inlet was greatly reduced when vortex generator was added, so that the effective function of the vortex generator was verified.
