The invention discloses a two-stage unscrewing wing driven by a metal air bag, relates to the technical field of aviation, and solves the problems that a deformation wing driving and transmission device is heavy, the wing surface deformation unfolding and folding ratio is low, and the aerodynamic configuration continuity of a multi-stage deformation wing surface is poor. A first-stage unscrewing wing, a second-stage unscrewing wing and an air path control system are arranged on an aircraft base body; the front edge end of the first-stage unscrewing wing is hinged to the aircraft base body, a first-stage air bag is arranged at the hinged position, the first-stage unscrewing wing is driven to be unfolded through the first-stage air bag, a wing spar at the rear end of the first-stage unscrewing wing is movably connected with the second-stage unscrewing wing, and the front edge end of the second-stage unscrewing wing is hinged to the sliding block. The sliding block can slide on a sliding rail fixed to the aircraft base body, a second-stage air bag is arranged at the connecting position of the sliding block and the sliding rail, and the second-stage air bag drives the second-stage unscrewing wing to be unfolded. The device is simple in structure, extremely small in mass and space occupation of the aircraft, high in output power volume ratio, rapid in response and easy to control, and the deformation wings are driven to be unfolded through the metal air bags.

    本发明公开了一种由金属气囊驱动的二级旋开翼,涉及航空技术领域,解决了变形翼驱动及传动装置繁重、翼面变形展收比低和多级变形翼面气动外形连续性差的问题。本发明飞行器基体上设置有第一级旋开翼、第二级旋开翼和气路控制系统;第一级旋开翼的前缘端部和飞行器基体铰接,铰接位置设置有一级气囊,通过一级气囊驱动第一级旋开翼展开,第一级旋开翼后端翼梁和第二级旋开翼活动连接,第二级旋开翼前缘端部和滑块铰接,滑块可在固定于飞行器基体上的滑轨上滑动,二者连接位置处设置有二级气囊,二级气囊驱动第二级旋开翼展开。本发明结构简单,对飞行器的质量和空间占用极小,通过金属气囊驱动变形翼展开,输出功率体积比高,响应快速,易于控制。
