The invention provides a tail-rotor-free tilting wing high-speed unmanned helicopter, and belongs to the field of unmanned aerial vehicles. Comprising a fuselage main body with a tilting mechanism, a main propeller and tilting wings, the tiltable wings are symmetrically mounted on the two sides of the fuselage main body through the tilting mechanism; in a normal flight stopping state, the tiltable wings are perpendicular to the ground; after the unmanned aerial vehicle takes off vertically, torsion is provided through steering engines of the tilting mechanisms, the torsion is transmitted through two bevel gears, the motion direction is changed, wings fixed to carbon tubes are controlled to rotate synchronously, and therefore the wings can rotate from the state perpendicular to the ground to the state parallel to the ground; differential motion of wings on two sides can be realized; meanwhile, by removing the tail rotor, in the vertical take-off and flat flight process, the reverse torque generated by downwash airflow of the main propeller is counteracted through differential motion of the tiltable wings and differential rotation of the propellers of the tiltable wings; the unmanned aerial vehicle has the advantages of tail rotor removal, high speed, high load, high endurance, low level flight resistance and the like.
本发明提出了无尾桨倾转翼高速无人直升机,属于无人机领域;包括带有倾转机构的机身主体,主螺旋桨和可倾转机翼;机身主体通过倾转机构在两侧对称安装可倾转机翼;正常停飞状态,可倾转机翼垂直于地面;当无人机垂直起飞后,通过倾转机构的舵机提供扭力,两个锥齿轮传递扭力并改变运动方向,控制固定在碳管的机翼同步转动,从而实现可机翼从垂直地面状态转动到平行地面状态:当两侧舵机输出的舵量不同时,可以实现两侧机翼的差速运动;同时,通过去尾桨,实现垂直起飞和平飞过程中,分别由可倾转机翼的差动和倾转机翼螺旋桨的差速转动抵消主螺旋桨的下洗气流产生的反扭距;本发明具有去尾桨、高速、高载重、高续航、低平飞阻力等优势。
