The invention provides a high-speed unmanned helicopter without a tail rotor and tilting wings, and belongs to the technical field of unmanned aerial vehicles. According to the technical scheme, the design scheme of the tilting mechanism is provided, and the tilting mechanism comprises a fixed wing, a fixed wing power assembly, a tilting assembly and a connecting and fixing assembly; two tail rotor removing schemes are provided, in the vertical take-off process, downwash airflow of a main propeller generates different forces in the horizontal direction on wings on the two sides through differential motion of the wings so as to counteract the reverse torque, and in the level flight process, differential motion of motors on the wings enables the rotating speeds of the propellers on the two sides to be different so as to generate a reasoning difference so as to counteract the reverse torque; a high-speed flight scheme is provided, and the rotating speed of a wing propeller is increased in the level flight process so as to increase forward flight thrust. The unmanned aerial vehicle has the advantages of tail rotor removal, high speed, high load, long endurance, low level flight resistance and the like, and the unmanned aerial vehicle can be put into use in task scenes of long endurance, high navigational speed, load carrying and the like.
本发明提出了无尾桨倾转翼高速无人直升机,属于无人机技术领域范畴。本发明的技术方案包括:提供一种倾转机构设计方案,包括固定翼、固定翼动力组件、倾转组件、连接与固定组件;提供两种去尾桨方案,包括垂直起飞过程中通过机翼差动使主螺旋桨的下洗气流对两侧机翼产生水平方向大小不同的力从而抵消反扭距,平飞过程中通过机翼上的电机差速运动,使得两侧螺旋桨转速不同产生推理差从而抵消反扭距;提供一种高速飞行方案,在平飞过程中增大机翼螺旋桨转速以增大前飞推力。本发明具有去尾桨、高速、高载重、高续航、低平飞阻力等优势,有利于该种无人机在长航时、高航速、载有负重等任务场景中投入使用。
