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.

    本发明属于变体机翼领域,公开了一种基于主动变形蒙皮的多形态变形机翼。多形态变形机翼包括从前至后顺序固定连接的固定块、弹性板和后缘块,在固定块和后缘块之间覆盖上下对称的主动变形蒙皮;上方的主动变形蒙皮在厚度方向上,从下至上依次叠加弹性支撑层、导热绝缘基体和弹性整流层,下方的主动变形蒙皮具有与上方的主动变形蒙皮对称的结构;导热绝缘基体内嵌入平行排列的若干根形状记忆合金丝,各形状记忆合金丝的前端固定在固定块上,后端固定在后缘块上,各形状记忆合金丝之间相互隔离而且绝缘。多形态变形机翼能够实现机翼弦向双程、双向变弯度,展向多形态扭转变弯度,拓展了机翼弯度对的变形范围。
