The invention mainly aims to provide a variable-attack-angle multi-mode ornithopter capable of simulating the flying attitude of insects, as shown in Figure 1, the ornithopter comprises an ornithopter body framework 2, wings 1, a flapping control mechanism 3 and a crawler walking mechanism 4, the flapping control mechanism is movably connected in a 60-degree guide rail 5 of the ornithopter body framework, and a half gear is embedded outside the ornithopter body framework; the half gear is meshed with a gear on a transmission shaft of the variable-attack-angle motor, the motor outputs power, the variable-attack-angle function is achieved, and variable-attack-angle motion and wing flapping motion are combined so that the wing tip track simulating insect flapping can be achieved. As shown in Figure 2, the crawler walking mechanism consists of a motor 6, a pair of meshed helical gears 7, a transmission shaft 8, a driven wheel (movably mounted on the fuselage), a driving wheel (fixedly connected to the two ends of the transmission shaft) 9 and a crawler, and a land advancing mode can be selected when the unmanned aerial vehicle is inconvenient to fly and is in an energy-saving mode.

    本发明的主要目的在于提供一种模拟昆虫飞行姿态的可变攻角多模态扑翼机,如图1所示包括机身骨架2、机翼1、扑动控制机构3和履带行走机构4,扑动控制机构活动连接在机身骨架的60度导轨5中,外嵌一个半齿轮,半齿轮和变攻角电机传动轴上的齿轮啮合,电机输出动力,达到变攻角的功能,变攻角运动和机翼扑动运动结合可以实现模仿昆虫扑动的翼尖轨迹;履带行走机构如图2所示由电机6、一队啮合的斜齿轮7、传动轴8、从动轮(活动安装在机身上)、主动轮(固接在传动轴两端)9、履带构成,在不便飞行和节能模式时可选择陆地行进模式。
