The invention discloses a four-flapping-wing aircraft and an attitude control system thereof, and relates to the technical field of micro aircrafts, and the four-flapping-wing aircraft comprises a fixed rack, a guide rod, a slide block mechanism, a pitching frame, a rolling frame, a pulley and a chord driving system. The fixed rack is provided with four cantilevers, a sliding block mechanism is installed on a guide rod, and the pitching frame and the rolling frame control pitching and rolling actions through steering engines respectively. The four pulleys are connected to the pitching frame, and each pulley is hinged to one wing. The string driving system comprises a guide wheel, a string and a crank, one end of the string is connected with the slider mechanism, and the other end bypasses the guide wheel and is connected with the pulley to realize wing flapping. Through the deflectable spars and fine steering engine control, efficient aerodynamic performance, enhanced thrust output and excellent flight flexibility and adaptability are achieved, meanwhile, due to the design of the crank sliding blocks, structural stress is relieved, the service life is prolonged, the aircraft adapts to multiple flight modes, and the environment adaptability and task execution efficiency of the aircraft are improved.
本发明公开一种四扑翼飞行器及其姿态控制系统,涉及微型飞行器技术领域,包括固定机架、导向杆、滑块机构、俯仰架、滚转架、滑轮和弦线驱动系统。固定机架有四个悬臂,导向杆上装有滑块机构,俯仰架和滚转架分别通过舵机控制俯仰和滚转动作。四个滑轮连接在俯仰架上,每个滑轮铰接一个翅翼。弦线驱动系统包括导向轮、弦线和曲柄,弦线一端连接滑块机构,另一端绕过导向轮连接滑轮,实现翅翼扑动。本发明通过可偏转翼梁和精细的舵机控制,实现了高效的气动性能、增强的推力输出、出色的飞行灵活性和适应性,同时曲柄滑块的设计减轻了结构应力,延长了使用寿命,并适应多种飞行模式,提升了飞行器的环境适应能力和任务执行效率。
