The invention provides a twistable bionic flapping-wing micro aircraft, according to the flight process, recorded by a high-speed camera, of a golden turtle, it is found that the rear wings of the golden turtle can generate active twisting motion in the flapping process, and the flapping mode can optimize aerodynamic characteristics and reduce energy consumption. A driving mechanism is composed of a motor and a two-stage speed reduction transmission mechanism; and the torsion mechanism realizes the torsion of the wings through a connecting rod positioning height difference in the crank rocker mechanism, so that the flapping-twisting coupling motion of the aircraft is realized. The flapping-twisting coupling motion of the bionic aircraft is achieved through the single driving mechanism, and the structure is exquisite and closer to the motion mechanism of insect flight.
本发明提供一种可扭转仿生扑翼微飞行器,通过高速摄像机所记录的金龟的飞行过程,发现金龟后翅在扑动过程会产生主动扭转运动,这种扑动方式可以优化气动特性减少能耗。本发明由一个电机和二级减速传动机构组成驱动机构;扭转机构通过曲柄摇杆机构中连杆定位高度差实现机翼的扭转,从而实现飞行器的扑扭耦合运动。本发明通过单驱动机构实现仿生飞行器的扑扭耦合运动,结构精巧,更贴近昆虫飞行的运动机理。
