The invention belongs to the technical field of aviation equipment, and relates to a shape memory alloy driven fishbone type variable camber wing which comprises a wing front-end rigid framework, a fishbone type flexible framework and a rear-end rigid framework which are sequentially connected end to end, and a shape memory alloy wire is arranged in the fishbone type flexible framework. The front end of the shape memory alloy wire is connected with a shape memory alloy spring; one end, far away from the shape memory alloy wire, of the shape memory alloy spring is connected with a wing front-end rigid framework; the rear end of the shape memory alloy wire is connected with the rear-end rigid framework; the dynamic stretching device composed of the shape memory alloy spring and the shape memory alloy wire shrinks after being electrified to generate pulling force to pull the rear-end rigid framework, so that the rear-end rigid framework deflects upwards or downwards; the variable camber wing can deflect upwards and downwards, so that the variable camber wing can adapt to different working conditions of an aircraft in the actual flight process.
本发明属于航空装备技术领域,涉及一种形状记忆合金驱动的鱼骨式变弯度机翼,包括:依序首尾相接的机翼前端刚性骨架、鱼骨式柔性骨架、后端刚性骨架,鱼骨式柔性骨架内设有形状记忆合金丝,形状记忆合金丝的前端连接有形状记忆合金弹簧,形状记忆合金弹簧远离形状记忆合金丝的一端连接机翼前端刚性骨架;形状记忆合金丝的后端连接后端刚性骨架;本发明的形状记忆合金弹簧、形状记忆合金丝组成的动力拉伸装置在通电后收缩产生拉力拉动后端刚性骨架,从而使得后端刚性骨架向上偏转或向下偏转;本发明变弯度机翼既能向上偏转又能向下偏转,因此能够适应飞机在实际飞行过程中的不同工况。
