摘要：

In order to satisfy the demand of inlet guide vane for advanced aero engine, optimize the design of the variable inlet guide vane's slot form, the numerical simulation method is used to investigate the performance of variable-camber vanes with different slot forms under different working conditions. Results show that the new variable inlet guide has a lower total pressure loss, it can bear bigger incoming Mach number and aft-blade rotation angle, the properties of attack angle also change. Good slot form makes the size and direction of the slot exit jet more reasonable, suppress the development of the boundary layer on the suction side of aft-blade, and the aft-blade leading edge with a smaller curvature can reduce the pressure coefficient. New variable-camber vanes have better performance and wider working range. © 2021, Editorial Department of Journal of Propulsion Technology. All right reserved.
