The invention belongs to the field of morphing wings, and discloses a polymorphic deformation wing based on an active deformation skin. The multi-form deformation wing comprises a fixed block, an elastic plate and a trailing edge block which are fixedly connected in sequence from front to back, and active deformation skins which are symmetrical up and down cover the space between the fixed block and the trailing edge block; an elastic supporting layer, a heat-conducting insulating base body and an elastic rectifying layer are sequentially stacked on the upper active deformation skin from bottom to top in the thickness direction, and the lower active deformation skin is of a structure symmetrical to the upper active deformation skin; a plurality of shape memory alloy wires which are arranged in parallel are embedded in the heat-conducting insulating substrate, the front end of each shape memory alloy wire is fixed on the fixed block, the rear end of each shape memory alloy wire is fixed on the rear edge block, and the shape memory alloy wires are mutually isolated and insulated. The polymorphic deformation wing can realize chordwise two-way and bidirectional bending and spanwise polymorphic torsion bending of the wing, and the deformation range of the wing bending pair is expanded.
