The influence of boundary layer suction on the aerodynamic performance of a two-dimensional mixed compression variable geometry inlet was studied. The preliminary calculation results show that the main reason of the inlet’s unstarting is the obstruction of throat caused by the smaller area of it. In this paper, the design of the suction scheme is carried out, and the suction is carried out in the severely separated part of the area. The ultimate goal is to design a relatively excellent suction scheme: when the inlet does not start, improving the the aerodynamic performance of the inlet to guarantee its starting. Improving the aerodynamic performance of the inlet as much as possible after its starting.And the influence of suction on the aerodynamic performance of inlet is studied.
