The generation of lift and thrust mainly depends on the formation of low-pressure vortices above the arc groove on the leading edge of the fan-wing, which makes the lift and thrust have a strong coupling relationship. How to decouple and control the lift and thrust is the key to the further engineering application of the fan-wing. When the geometric parameters of the fan-wing airfoil are determined, the leading edge opening angle has the greatest influence on the aerodynamic performance. Therefore, the method of installing leading edge winglets on the leading edge of a base fan-wing airfoil was considered to change the opening angle of the leading edge. By means of numerical simulation, the effects of single, double and three leading-edge winglets on lift and thrust of the fan at different installation angles, inflow velocities and angles of attack are compared and analyzed. The results show that the angle control of the leading edge winglet installation angle can not only improve the lift and thrust of the fan-wing, but also control the strength and position of the low-pressure vortices to meet the requirements of active control of the aerodynamic force of the fan-wing, so the attitude control of the fan-wing aircraft can be realized.
