The invention provides an inflatable deformation wing based on an elastic carbon fiber composite skin, and the inflatable deformation wing can be stored in a Z-shaped manner and comprises a soft air-retaining inner bag and the elastic carbon fiber composite skin. On the basis of a soft air-retaining inner bag, an elastic carbon fiber composite skin is provided to directionally reinforce a soft inflatable deformation wing, and the soft air-retaining inner bag and the elastic carbon fiber composite skin are bonded through silicone rubber. Meanwhile, the invention further provides a structural optimization design method of the approximate airfoil profile, and the optimal length and number of the spanwise braces can be rapidly and accurately determined. On the premise of ensuring light weight and high storage efficiency, the elastic carbon fiber composite skin can remarkably improve the bearing performance and the shape preserving capacity of the inflatable deformation wing, the uneven appearance of the soft inflatable deformation wing is improved, the inflatable deformation wing has a better aerodynamic appearance, the rigidity of the wing is remarkably improved, and the service life of the wing is prolonged. And a new technical approach is provided for engineering application of the inflatable deformation wing.
