According to the requirements of wing design and the engineering mechanical properties of materials,this paper designs and manufactures a kind of wing structure made of the integral molding of all-composite materials which meets the requirements of engineering application based on the shape of the given wing.This paper com-prehensively verifies the structure of the wing by the methods of finite element simulation analysis and engineering statics tests.The results of finite element simulation analysis are well consistent with the results of engineering statics tests,which satisfies the requirement of the engineering mechanical allowable value of composite materials and the stiffness design requirement that the maximum deformation of the wing is not more than the 8%of the span length of the half wing.The mechanical bearing capacity of the wing has been fully verified.
