The invention belongs to the technical field of vertical take-off and landing unmanned aerial vehicles, and provides a dish-shaped three-rotor vertical unmanned aerial vehicle using tilting coaxial motors and a working method of the dish-shaped three-rotor vertical unmanned aerial vehicle. According to the saucer-shaped three-rotor-wing vertical unmanned aerial vehicle using the tilting coaxial motors, by controlling the angle of the tilting steering engine and the rotating speed of the multiple rotor wings, a main power source is changed into a pair of coaxial incongruous motors, vertical take-off and landing of the fixed-wing unmanned aerial vehicle are achieved, switching between a vertical take-off and landing mode and a fixed-wing flight mode is achieved, and the saucer-shaped three-rotor-wing vertical unmanned aerial vehicle has the advantages of being simple in structure and convenient to use. And the voyage and the load capacity are increased. The unmanned aerial vehicle adapts to more scenes, and compared with a traditional fixed-wing unmanned aerial vehicle, vertical take-off and landing can be achieved, and a special take-off and landing runway is not needed; the saucer-shaped fuselage and the coaxial different-rotation rotors with large tension and high efficiency are combined, the lift coefficient is large, the stall attack angle is high, the pitching stability is good, and large load can be achieved under the condition that a small space is occupied when the aircraft works under the low Reynolds number.
本发明属于垂直起降无人飞行器技术领域,提供了一种使用倾转共轴电机的碟形三旋翼垂起无人机及其工作方法。本发明的目的在于提供一种使用倾转共轴电机的碟形三旋翼垂起无人机,通过控制倾转舵机的角度和多个旋翼的转速,将主要动力源改为一对共轴异向电机,实现固定翼无人机的垂直起降,在垂直起降模式和固定翼飞行模式之间切换,并增大其航程和载重量。本发明适应更多场景,相对于传统固定翼无人机,可以实现垂直起降,无需专用的起降跑道;将碟形机身和大拉力、高效率的共轴异转旋翼相结合,升力系数大,失速迎角较高,俯仰稳定性好,在低雷诺数下工作可在占用很小空间的情况下实现较大的载重。
