He invention discloses a space five-rod flapping-wing aircraft based on rigid-flexible coupling. The flapping-wing aircraft consists of a fuselage, a gear transmission system, a space five-rod mechanism, two side wings and a tail wing mechanism. A direct current motor drives the gear transmission system, and then the force of deceleration and torque increase is input into the space five-rod mechanism to sequentially drive a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod; then due to the action of a flexible ball pair in the space five-rod mechanism, the two side wings do regular 8-shaped motion; the fourth connecting rod in the space five-rod mechanism is used as a rocker to drive a first wing connecting rod, so that wing folding motion isrealized; and a tail wing is driven by two stepping motors, so that pitching and steering of the flapping-wing aircraft are realized. The space five-rod flapping-wing aircraft has the characteristicsof light overall weight, less driving links, high flight efficiency and high practicability; and flapping-twisting-swinging-folding coupling can be realized.
本发明公开了一种基于刚柔耦合的空间五杆扑翼飞行器,该扑翼飞行器由机身、齿轮传动系统、空间五杆机构、两侧机翼和尾翼机构所组成。直流电机驱动齿轮传动系统,经过减速增矩的力再输入到空间五杆机构依次带动连杆一、连杆二、连杆三和连杆四,然后由于空间五杆机构中柔性球副的作用,两侧机翼做有规律的8字型运动;空间五杆机构中的连杆四又作为摇杆带动机翼连杆一,从而实现折翼运动;尾翼由两个步进电机驱动,从而实现该扑翼飞行器的俯仰和转向。本发明具有整体质量轻、驱动原动件少、能都实现扑动‑扭转‑挥摆‑折叠耦合的仿自然鸟类扑翼飞行器,同时兼顾飞行效率高和实用性高的特点。
