The helicopter comprises a helicopter body, a rotor wing is arranged at the top of the helicopter body, a rotor wing reaction torque balancing device is arranged at the tail of the helicopter body, and the rotor wing reaction torque balancing device is used for achieving mechanical balance of the reaction torque generated by the rotor wing; the rotor reaction torque balancing device comprises a frame assembly and a plurality of fins arranged in the frame assembly, a cylindrical structure is defined by the frame assembly, a latticed structure formed by connecting the fins is arranged on the inner wall of the frame assembly, and the surfaces of the fins are parallel to the central axis of the frame assembly; the surface of the wing panel is perpendicular to the rotating plane of the rotor wing, the frame assembly is arranged below the rotor wing, when the rotor wing rotates, downwash flow is generated below the rotor wing, and the downwash flow forms balance torque for balancing the reaction torque of the rotor wing on the surface of the wing panel. The helicopter provided by the invention does not need other high-speed rotating parts such as a tail paddle or a contra-rotating rotor, so that the number of moving parts on the helicopter is reduced, and the energy consumption and the power loss are reduced.
本申请公开了一种可平衡旋翼反扭矩的无尾浆直升机,包括机身,机身的顶部设置有旋翼,机身的尾部设置有旋翼反扭矩平衡装置,旋翼反扭矩平衡装置用以实现对旋翼产生的反扭矩的力学平衡;旋翼反扭矩平衡装置包括框架组件及设置在框架组件内的若干个翼片,框架组件围成筒状结构,框架组件的内壁上设置有由若干个翼片相互连接形成的网格状结构,翼片的表面与框架组件的中心轴线平行;翼片的表面与旋翼的旋转平面垂直,框架组件设置在旋翼的下方,当旋翼转动时,旋翼下方产生下洗气流,下洗气流在翼片表面形成平衡旋翼反扭矩的平衡力矩。本申请提供的直升机无需尾浆或对转旋翼等其它高速旋转部件,直升机上的运动部件减少,减小了能耗及功率损失。
