Bionic wing parametric deformation method based on exponential decay curve leading edge deformation

The invention relates to a bionic wing parameterization deformation method based on exponential decay curve front edge deformation, which combines bionics and curve parameterization, and applies a specific front edge concave-convex structure of a seat head whale fin to a three-dimensional wing front edge. Aiming at a stalling motion state under a large attack angle, the purposes of reducing resistance, increasing lift and delaying a stalling angle are achieved; the front edge of a standard three-dimensional smooth wing is controlled to deform according to a parameterized exponential decay curve to obtain a concave-convex structure similar to the front edge of a seating head whale fin, and the obtained three-dimensional wing with the concave-convex front edge can effectively delay a stall angle and improve aerodynamic performance. The invention can be widely applied to rudder sheets and turbines in the fields of aviation, spaceflight, navigation and industrial energy power. 本发明涉及一种基于指数衰减曲线前缘变形的仿生机翼参数化变形方法，本方法将
