The invention relates to the technical field of unmanned aerial vehicle equipment, in particular to a coaxial dual-rotor unmanned aerial vehicle controlled by a single tilt. The coaxial dual-rotor unmanned aerial vehicle controlled by the single tilt comprises a fuselage, a rotor system, a power system and a control mechanism used for adjusting the flight attitude of the fuselage. According to the coaxial dual-rotor unmanned aerial vehicle controlled by the single tilt, the course of the vehicle body is changed in a semi-differential mode through the control mechanism, course control is achieved by changing the attack angle of the lower rotor assembly, and under the combined action of the power system and the control mechanism, the unmanned aerial vehicle is controlled by the single tilt; the front flight and side flight actions of the unmanned aerial vehicle are controlled only by changing the transverse and longitudinal periodic pitch changing mode of the lower rotor wing assembly, the lower rotor wings can rotate in the horizontal direction and can also rotate in a plane with a certain inclination angle on the horizontal plane, the design of a control mechanism is optimized, the complexity of an unmanned aerial vehicle dynamic model is reduced, and the control efficiency is improved. The aerodynamic interference between the double rotors is reduced, and the controllability of the attitude of the fuselage and the flight stability are improved in the flight process.

    本发明涉及无人机设备技术领域,具体涉及一种单倾斜操纵的共轴双旋翼无人机。该单倾斜操纵的共轴双旋翼无人机包括机身、旋翼系统、动力系统,以及用于调整机身飞行姿态的操纵机构。该单倾斜操纵的共轴双旋翼无人机利用操纵机构对机身采取半差动方式改变航向,通过改变下旋翼组件的迎角来实现航向操纵,在动力系统和操纵机构的共同作用下,只改变下旋翼组件横、纵向周期变距地方式来控制无人机的前飞和侧飞的动作,下旋翼不仅可以做水平方向的转动,还可以在水平面上是实现一定倾斜角度的平面内旋转,优化了操纵机构设计,降低了无人机动力学模型的复杂度,减少了双旋翼之间的气动干扰,在飞行过程中,提高对机身姿态的可控性以及飞行稳定性。
