The invention discloses a two-stage unscrewing wing with a high unfolding and folding ratio, relates to the technical field of aircrafts, and solves the problems that a deformation wing driving and transmission device is heavy, the wing surface deformation unfolding and folding ratio is low, the aerodynamic configuration continuity of a multi-stage deformation wing surface is poor and the like. 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 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 air bag drives the first-stage unscrewing wing to be unfolded, and the rear end of the first-stage unscrewing wing is connected with the second-stage unscrewing wing; the front end of the second-stage unscrewing wing is hinged to a sliding block, the sliding block is arranged on the aircraft base body in a sliding mode, and a tandem type air bag is arranged between the rear end of the second-stage unscrewing wing and the aircraft base body and drives the second-stage unscrewing wing to unfold. According to the invention, the mass and the space occupation of the aircraft are small, the output power volume ratio is high, the response is fast, the control is easy, and compared with an independent metal air bag, a larger driving stroke and a larger rotation angle are provided.
本发明公开了一种具有高展收比的二级旋开翼,涉及飞行器技术领域,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等问题。本发明飞行器基体上设有第一级旋开翼、第二级旋开翼和气路控制系统;第一级旋开翼前端和飞行器基体铰接,铰接处设有一级气囊,一级气囊驱动第一级旋开翼展开,第一级旋开翼后端和第二级旋开翼连接;第二级旋开翼前端与滑块铰接,滑块滑动设在飞行器基体上,第二级旋开翼后端与飞行器基体之间设有串联式气囊,串联式气囊驱动第二级旋开翼展开。本发明对飞行器的质量和空间占用小,输出功率体积比高,响应快,易于控制,相比单独的金属气囊,提供了更大的驱动行程和转动角度。
