The invention discloses an air-ground dual-purpose plant protection unmanned aerial vehicle and a control method thereof, belongs to the technical field of unmanned aerial vehicles, and aims to solve the technical problems that a rudder ducted fan adjusts the airflow direction through blade grids, the blade grids can hinder passing airflow to form resistance to influence the power of the fan, and noise is also formed when the airflow impacts the blade grids. A supporting arm and a rotor wheel installed at the end of the supporting arm are installed outside the aircraft body in a hinged mode, a duct is formed in the aircraft body, a rotating cylinder is arranged in the duct, a deflectable cambered surface rotating ring is rotatably installed in the rotating cylinder, deflection of the cambered surface rotating ring is controlled through a deflection motor, and a driving rotor is installed in the cambered surface rotating ring. Flight is controlled through the driving rotor wings in the ducts, so that the unmanned aerial vehicle can shuttle from the forest, the driving rotor wings are controlled through the rotating cylinders and the cambered surface rotating rings, the situation that airflow impacts the blade grids when the blade grids are used is avoided, airflow passing is smoother, power loss is smaller, and meanwhile noise is reduced.

    本发明公开了一种陆空两用植保无人飞行器及其控制方法,属于无人机技术领域,以解决舵涵道风扇通过叶珊调节气流方向,叶珊会对经过的气流产生阻碍形成阻力影响风扇的动力,以及气流撞击叶珊同时也会形成噪音的技术问题,机体外部铰接安装有支臂,以及安装在支臂端头的旋翼轮,机体中设置有涵道,涵道内部设置有转筒,转筒中转动安装有可偏转的弧面转环,弧面转环通过偏转电机控制偏转,以及安装在弧面转环内的驱动旋翼,飞行器可以在飞行状态时折叠,通过涵道内的驱动旋翼进行控制飞行,使其有利于在从林中穿梭,通过转筒和弧面转环控制驱动旋翼,避免使用叶珊时气流撞击叶珊,使气流经过更加顺畅,动力损失更小,同时也减少噪音。
