To design a flapping-wing micro air vehicle (FWMAV), the hovering flight action of a beetle species (Protaetia brevitarsis) was captured, and various parameters, such as the hindwing flapping frequency, flapping amplitude, angle of attack, rotation angle, and stroke plane angle, were obtained. The wing tip trajectories of the hindwings were recorded and analyzed, and the flapping kinematics were assessed. Based on the wing tip trajectory functions, bioinspired wings and a linkage mechanism flapping system were designed. The critical parameters for the aerodynamic characteristics were investigated and optimized by means of wind tunnel tests, and the artificial flapping system with the best wing parameters was compared with the natural beetle. This work provides insight into how natural flyers execute flight by experimentally duplicating beetle hindwing kinematics and paves the way for the future development of beetle-mimicking FWMAVs.
为了设计一种扑翼微型飞行器（FWMAV），捕捉了一种甲虫（短翅扁锹甲）的悬停飞行动作，并获取了各种参数，如后翅扑动频率、扑动幅度、攻角、旋转角和冲程平面角。记录并分析了后翅的翼尖轨迹，并评估了扑动运动学。基于翼尖轨迹函数，设计了仿生翅膀和连杆机构扑动系统。通过风洞试验研究并优化了空气动力学特性的关键参数，并将具有最佳翅膀参数的人工扑动系统与天然甲虫进行了比较。这项工作通过实验复制甲虫后翅运动学，深入了解了天然飞行者如何执行飞行，并为模仿甲虫的FWMAV的未来发展铺平了道路。
