The invention discloses a sweepback wing distributed unequal-diameter paddle disc tilting rotorcraft and a control method thereof. The sweepback wing distributed unequal-diameter paddle disc tilting rotorcraft comprises a rotorcraft body, wings, a tilting rotor group, an undercarriage, a horizontal tail and a vertical tail, the number of the tilting rotors is four, the tilting rotors are connected to the leading edges of the wings through supporting rods, and the area of a propeller disc close to the tips of the wings is larger than that of a propeller disc close to the roots of the wings, so that the flight efficiency of the aircraft during low-speed flight and the flight speed of the aircraft during high-speed flight are both considered. Moreover, the sweepback of the wings is beneficial to improving the stability of the tilt rotorcraft flying in a fixed wing mode, and the environmental adaptability of the aircraft is improved. According to the method, the efficiency of the tilt rotorcraft in the hovering and cruising states is considered, the aircraft structure is simple, and aircraft attitude control and flight control software design are facilitated.

    本发明公开了一种后掠机翼分布式非等直径桨盘倾转旋翼机及其控制方法,包括:机身、机翼、倾转旋翼组、起落架、水平尾翼及垂直尾翼;倾转旋翼有四个,并通过撑杆连接在机翼前缘,靠近机翼翼尖处的桨盘面积要比靠近机翼翼根处的桨盘面积大,以此来兼顾飞机低速飞行时的飞行效率和高速飞行时的飞行速度,且机翼后掠有利于提高倾转旋翼机在固定翼模式飞行时的稳定性,提高了飞机的环境适应能力。本发明兼顾了倾转旋翼机在悬停和巡航状态下的效率,且飞机结构较为简洁,有利于飞机姿态控制,飞控软件设计。
