The invention relates to a variable-diameter unmanned tilting rotorcraft, and belongs to the technical field of aircraft design. The unmanned tilting rotorcraft comprises a front wing and a rear wing,the two ends of the front wing and the two ends of the rear wing are provided with rotor wings respecitvley, the number of the rotor wings is four, the rotor wings are of a variable-diameter structure, and when the tilting rotorcraft works in a helicopter mode, the rotor wings are in a vertical large-diameter state; when the tilting rotorcraft works in a fixed-wing mode and flies flatly, the rotors are in a horizontal small-diameter state. The tilt rotor aircraft solves the problems that a common tilt rotor aircraft is large in propeller disc load and low in hovering efficiency in a helicopter mode and is low in cruising efficiency in a fixed wing mode.

    本发明涉及一种变直径无人倾转旋翼机,属于飞行器设计技术领域。该无人倾转旋翼机包括前机翼和后机翼,前机翼和后机翼两端各布置一套旋翼,共四个旋翼,所述旋翼为变直径结构,倾转旋翼机工作在直升机模式飞行时,旋翼处于垂直大直径状态;倾转旋翼机工作在固定翼模式平飞时,旋翼处于水平小直径状态。本发明解决了普通倾转旋翼机在直升机模式飞行桨盘载荷大,悬停效率低,在固定翼模式飞行时巡航效率低的问题。
