The invention provides a hyperelastic ejection rotor unmanned aerial vehicle, which relates to the field of unmanned aerial vehicle design and comprises a vehicle body assembly, an elastic energy storage assembly, a deformation traction assembly and a high-energy-efficiency hyperelastic energy storage device combining a spring, a hyperelastic strain gauge and a hyperelastic rope, a hyperelastic strain gauge, a hyperelastic rope and an inner core spring in the elastic energy storage assembly are indirectly driven to generate elastic deformation through winding contraction of a winding contraction elastic rope in the deformation traction assembly so as to store potential energy, and instantaneous release of the potential energy stored by the elastic energy storage assembly is achieved through winding fracture of the winding contraction elastic rope. High driving force is provided for ejection lift-off by utilizing the strong counter-acting force of the ground to the unmanned aerial vehicle at the moment of potential energy release, a very high flying speed is obtained in a short time, and the flying maneuverability of the unmanned aerial vehicle is improved; the elastic structure is used for storing energy at the high-speed landing moment, impact force is reduced, structural damage of the unmanned aerial vehicle is avoided, and safe landing of the unmanned aerial vehicle is protected.

    本发明提供一种超弹性弹射旋翼无人机,涉及无人机设计领域,包括机体组件、弹性储能组件、变形牵引组件,采用了弹簧、超弹性应变片以及超弹性绳结合的高能量效率超弹性储能装置,通过变形牵引组件中缠绕收缩弹性绳的缠绕收缩间接带动弹性储能组件中超弹性应变片、超弹性绳以及内芯弹簧产生弹性形变以储存势能,通过缠绕收缩弹性绳的缠绕断裂实现弹性储能组件存储势能的瞬时释放,利用势能释放瞬间地面对无人机强大的反作用力为弹射升空提供高驱动力,在短时间内获得很大的腾空速度,提高无人机腾空的机动性;高速落地瞬间借助弹性结构储能,减小冲击力,避免无人机结构损坏,保护无人机安全落地。
