The invention discloses a tilting wing device of a helicopter, belongs to the technical field of helicopter production, and aims to solve the technical problems that a protection device is mounted on a propeller blade, the helicopter is easier to drive, and the bearing capacity of a transmission shaft is reduced. According to the technical scheme, a support is installed at the top of a machine body in a T shape, cross-shaped annular rails are hung on the two sides of the support, and two motors control the rails to deflect forwards and backwards; two engines are installed above the track and are opposite in rotation direction, a rotating disc, paddles, roller shafts, rollers and the like are installed on a transmission shaft below the track, the rollers make contact with the lower portion of the track to roll when the paddles rotate, and lift force generated by the paddles is provided for the fuselage through the rollers, the track and a support. When the tracks drive the paddles and the like to deflect, lift force and forward and backward thrust are generated, so that the helicopter is lifted off, flies, turns and flies reversely. The larger the deflection angle of the engine throttle and the track is, the higher the flight speed of the helicopter is. The method is suitable for helicopters and unmanned aerial vehicles.
一种直升机的倾转翼装置,属于直升机生产技术领域,所要解决的技术问题:给螺旋桨桨叶安装防护装置、驾驶直升机更容易、减轻传动轴的承载力。技术方案要点是:支架呈“T”形安装在机身顶部,支架两侧悬挂十字环形轨道,两台电机控制轨道向前、后偏转角度;轨道上方安装两台发动机,旋转方向相反,轨道下方传动轴上安装转盘、桨叶、滚轮轴、滚轮等,桨叶旋转时滚轮与轨道下方接触滚动,桨叶产生的升力通过滚轮、轨道和支架提供给机身。轨道带动桨叶等偏转时产生升力和向前、向后的推力,使直升机升空、飞行、转弯和倒飞。发动机油门和轨道偏转角度越大,直升机的飞行速度就越大。该发明适用于直升机和无人机。
