The wing structure mainly comprises a flexible trailing edge structure 1 coated by a flexible skin and a leading edge rigid section 2; the flexible rear edge structure 1 is formed by sequentially hinging a plurality of rigid sections 4, and the flexible rear edge structure and the front edge rigid section 2 form an approximate dinosaur tailbone structure integrally; the upper and lower wing surfaces of the flexible trailing edge structure are provided with alloy wires along the chord direction of the wing profile. When the shape memory alloy wire group of the upper airfoil surface of the flexible trailing edge structure 1 is heated, the length of the shape memory alloy wire group is shortened, and the whole flexible trailing edge structure 1 deforms upwards; whereas a downward deformation occurs. The wing has the characteristics of simple structure and large power weight, and can actively change the wing profile to obtain the optimal aerodynamic characteristics; the wings can obtain different aerodynamic characteristics; and the modularized assembly design is adopted, so that the internal space of the wing is greatly saved.)
