A seamless deformation structure that changes the curvature of the main airfoil has a positive effect on improving the aerodynamic performance of long-range aircraft and reducing noise. Aiming at the problems of obvious wrinkles and heavy weight of rigid mechanism driven skin, this paper describes a compliant mechanisms-based leading-edge of morphing wing with a seamless deformation structure. In order to avoid the wrinkling of the wing skin, the driving points and the driving forces on the deformed skin were designed. In addition, the leading-edge flexible rib designed by the topology optimization method of flexible mechanism can make the wing leading-edge deflect downward by 17°. Finally, a set of experimental prototypes and experimental platforms were manufactured for the wing load-bearing deformation experiment. Experiment shown that the aerodynamic performance of the variable camber morphing wing was improved and can resist aerodynamic loads well.
