The invention discloses a design method of a self-adaptive wing profile. Firstly, parameterized description of a selected initial wing profile is obtained with a CST parameterization method, an optimal design variable of local deformation is determined, populations are initialized with a selected optimization algorithm, domination sequencing is performed on the populations under the conditions that the lift-to-drag ratio reaching the maximum when the lift coefficient CL is equal to 0.9 and the maximum bending stress reaching the minimum after change of leading edge camber are taken as optimization objects and non-plastic deformation is taken as a constraint, and finally, an optimized wing profile meeting the terminal conditions is selected. With pneumatic characteristics expected by the wing profile as the design objects, a constraint relation between the self-adaptive wing profile and an original wing profile is established, a reasonable target wing profile can be provided for design of a deformation driving
