The invention relates to the technical field of helicopters, and in particular relates to a tail rotor structure. The tail rotor structure comprises a vertical tail wing; a plurality of ducts are arranged on the vertical tail wing; a first power assembly and a second power assembly are arranged in each duct; the first power assembly comprises a first paddle and a first driving piece for driving the first paddle to rotate; the second power assembly comprises a second paddle and a second driving piece for driving the second paddle to rotate, the first paddle and the second paddle are coaxially arranged, the rotating direction of the first paddle is opposite to that of the second paddle, and the acting force generated by the first paddle and the acting force generated by the second paddle arethe same in direction. The multiple ducts are arranged, the two sets of power assemblies are arranged in each duct, and the directions of tension generated by the paddles in the two sets of power assemblies are the same, so that the power of the tail rotor structure can be greatly improved, the reverse torque of a high-power engine can be matched, and the carrying capacity of an unmanned aerial vehicle is improved.
本发明涉及直升机技术领域,尤其涉及一种尾旋翼结构及直升机,尾旋翼结构包括垂直尾翼,所述垂直尾翼上设置有多个涵道,每个涵道中均设置有第一动力组件和第二动力组件,所述第一动力组件包括第一桨叶和驱动所述第一桨叶转动的第一驱动件,所述第二动力组件包括第二桨叶和驱动所述第二桨叶转动的第二驱动件,所述第一桨叶和所述第二桨叶同轴设置,所述第一桨叶与所述第二桨叶的转向相反,且所述第一桨叶与所述第二桨叶产生的作用力方向相同。本发明通过设置多个涵道,并在每个涵道中设置两组动力组件,以及使两组动力组件中的桨叶产生的拉力方向相同,能够大幅提高尾旋翼结构的动力,可匹配大动力发动机的反扭力矩,提高无人机的载量。
