The coaxial unmanned aerial vehicle comprises a main shaft, a rotor wing structure, a variable pitch structure and an undercarriage structure, each rotor wing structure comprises a power set, a propeller hub and a plurality of sets of blades, the power sets drive the propeller hubs to rotate to generate centrifugal force so that the blades can be unfolded, and limiting pieces used for limiting the unfolded blades to rotate to be folded are further arranged between the propeller hubs and the blades; the variable-pitch structure comprises an inclinator and a plurality of groups of steering engines, a total pitch part is arranged between the inclinator and the paddle, a variable-pitch part connected with the inclinator is arranged at the output end of each group of steering engines, the steering engines drive the variable-pitch parts to move so as to enable the inclinator to incline or move up and down along the main shaft, and the paddle rotates in the axis direction of the main shaft; the undercarriage structure comprises a plurality of sets of supporting pieces, and reset pieces used for resetting the supporting pieces from the folded state to the supporting state are arranged between the supporting pieces and the main shaft. The coaxial unmanned aerial vehicle has the advantages that the coaxial unmanned aerial vehicle is suitable for a take-off mode of gun barrel launching, and compared with an existing unmanned aerial vehicle, the take-off mode of the coaxial unmanned aerial vehicle is more diversified.
本发明提供一种共轴无人机,包括主轴、旋翼结构、变距结构以及起落架结构,旋翼结构均包括动力组、桨毂以及多组桨叶,动力组驱动桨毂转动产生离心力以使桨叶展开,桨毂与桨叶之间还设有用于限制展开的桨叶转动至折叠的限位件;变距结构包括倾斜器以及若干组舵机,倾斜器与桨叶之间设有总距件,每组舵机的输出端上均设有与倾斜器连接的变距件,舵机驱动变距件运动以使倾斜器倾斜或沿主轴上下运动,且桨叶沿主轴的轴线方向转动;起落架结构包括若干组支撑件,支撑件与主轴之间具有用于将支撑件由折叠状态复位至支撑状态的复位件;本发明优点是适用于炮筒发射的起飞方式,相较于现有的无人机,该共轴无人机的起飞方式更为多样化。
