The invention discloses a takeoff and steering method of a novel bird-imitating flapping-wing aircraft. A driving motor is fixed to the middle of the front end of a rack and drives a first driving gear to rotate, and two symmetrically-arranged flapping assemblies are arranged on the two sides of the first driving gear; two wing surface folding and unfolding mechanisms are symmetrically arranged on the left side and the right side of the rack, an inner wing in each wing surface folding and unfolding mechanism is hinged to a flapping rod in the flapping assembly on the same side, and an outer wing folding and unfolding mechanism is arranged on each wing surface folding and unfolding mechanism; a moving frame in the steering mechanism and the rack form a sliding pair and are driven by a driving piece, and each push rod and a telescopic rod in the wing face unfolding and folding mechanism on the same side form a ball pair and form a sliding pair with the moving frame. According to the invention, flapping motion, outer wing bending motion and wing surface folding and unfolding motion are combined together, so that the flapping wings generate large lift force and thrust to realize takeoff, and the unfolding areas of the wing surfaces on the two sides form an area difference to adjust the flight attitude and realize steering.

    本发明公开了一种新型仿鸟扑翼飞行器的起飞和转向方法。本发明中驱动电机固定于机架前端中部,并驱动驱动齿轮一转动,驱动齿轮一的两侧设有对称设置的两个扑动组件;机架左、右两侧设有对称设置的两个翼面展收机构,每个翼面展收机构中内翼与同侧扑动组件中扑动杆铰接,每个翼面展收机构上设有一个外翼折展机构;转向机构中移动架与机架构成滑动副,并由驱动件驱动,每个推杆与同侧翼面展收机构中伸缩杆构成球副,并与移动架构成滑动副。本发明通过将扑动运动、外翼弯曲运动以及翼面收展运动结合在一起,使扑翼产生较大升力和推力,实现起飞,并通过使两侧各翼面的展开面积形成面积差来调整飞行姿态,实现转向。
