The invention relates to a wing for enhancing the aerodynamic performance of a flapping wing based on bionic leading edge wing feathers, belongs to the technical field of aircraft design and manufacturing, solves the problem that the existing wing of the flapping wing is difficult to fly with high maneuverability and variable attitude, and can effectively improve the leading edge deflection of the wing and improve the flight performance of the flapping wing. The bionic front edge wing plume is introduced to the front edge of the curved wing body to form a flow direction vortex pair, and the evolution rule of an incoming flow boundary layer is improved; the separation phenomenon of the boundary layer at the large attack angle of the flapping wing is inhibited and/or improved through vortex-induced downwash and momentum transfer, and the aerodynamic performance of the flapping-wing unmanned aerial vehicle is improved; the bionic leading edge wing feather does not change the aerodynamic shape of an existing wing, hardware design can be completed only by adding a small-scale turbulent flow structure to the leading edge, the overall structure is simple, and maintenance is easy; and through free control of wing feather feature shapes, numbers and angles, the pneumatic lifting of the flapping-wing unmanned aerial vehicles with different flight working conditions and performance requirements is served.
