The invention relates to an autonomous take-off and landing type bionic butterfly flapping wing aircraft. The autonomous take-off and landing type bionic butterfly flapping wing aircraft comprises a front-end rack, a rear-end rack, a pair of wings located on the two sides of the front-end rack, a battery fixed to the rear-end rack, steering engines connected with the wings, and elastic leg mechanisms arranged at the bottoms of the front-end rack and the rear-end rack. The elastic potential energy is contracted when the wings flap downwards so as to generate elastic potential energy, and is expanded when the wings flap upwards so as to release the elastic potential energy. By arranging the elastic leg mechanisms, the elastic leg mechanisms contract to generate elastic potential energy when the wings flap downwards and expand to release the elastic potential energy when the wings flap upwards, and the elastic potential energy and lift force generated by the wings jointly act on the aircraft body, so that the aircraft completes autonomous take-off similar to a butterfly take-off mode; therefore, the problem that the aircraft is difficult to take off and crashes due to insufficient lift force if the throwing angle is incorrect due to throwing type take-off is avoided.

    本申请是关于一种自主起降式仿生蝴蝶扑翼飞行器。该自主起降式仿生蝴蝶扑翼飞行器包括前端机架、后端机架、位于前端机架两侧的一对机翼,以及固定在后端机架上的电池,还包括与机翼连接的舵机,设置于前端机架和后端机架的底部的弹性腿部机构,用于在机翼向下扑动时收缩以产生弹性势能,在机翼向上扑动时扩张以释放弹性势能。本申请通过设置弹性腿部机构,使其在机翼向下扑动时收缩以产生弹性势能,在机翼向上扑动时扩张以释放弹性势能,该弹性势能与机翼产生的升力共同作用于飞行器本体,使得飞行器完成类似蝴蝶起跳式的自主起飞,从而避免了手抛式起飞,若抛出角度不对,导致飞行器因升力不够而难以起飞并发生坠毁的问题。
