A dragonfly-imitated ornithopter comprises a nose, a machine body, four support frames, two front flapping wings, two rear flapping wings and an empennage, the machine body comprises a machine shell and four power systems. Each power system comprises a steering engine, a motor, a speed reducer, a driving gear, a steering engine connecting piece, a small bearing, a torsion piece, a large bearing, an L-shaped transmission shaft, a wing connecting piece, a driven gear and a U-shaped connecting piece. The ornithopter has the advantages that: the rotation of the steering engine and the motor is directly converted into the flapping and the rotation of the front flapping wing and the rear flapping wing, and an intermediate mechanism is not needed, so that the aircraft can finish various more complex actions and is closer to real dragonfly flight. The two actions of twisting and flapping of the flapping wings can be carried out independently and can also be cooperated at the same time. The twofront flapping wings and the two rear flapping wings are respectively provided with an independent power system, working conditions do not influence each other, even if one flapping wing breaks down,the other three flapping wings can still operate normally, and therefore stable landing of the flapping-wing air vehicle is achieved.
一种仿蜻蜓式扑翼飞行器包括机头、机身、四个支撑架、两个前扑翼、两个后扑翼和尾翼;机身包括机壳和四个动力系统;每个动力系统包括舵机、电机、减速器、主动齿轮、舵机连接件、小轴承、扭转件、大轴承、L形传动轴、翅膀连接件、从动齿轮和U形连接件;本发明效果:舵机、电机的转动直接转换为前扑翼和后扑翼的扑动和旋转,不需要中间机构,可使飞行器完成各种较复杂的动作,使其更接近真实蜻蜓飞行。扑翼的扭转和扑动两种动作可以单独进行,也可以同时协作。两个前扑翼和两个后扑翼均装有各自独立的动力系统,工作条件互不影响,即使有一个发生故障,另外三个仍可正常运行,从而实现扑翼飞行器的平稳降落。
