The invention discloses a tilting wing device of a single-shot helicopter, belongs to the technical field of helicopter production, and aims to solve the technical problem of how to mount a protection device on a propeller blade and arrange a bilaterally symmetrical double-propeller tilting wing structure so as to enable the helicopter to be more easily piloted. According to the technical scheme, the layout of two propellers which are symmetrical left and right is adopted, and the rotation directions are opposite; two horizontal transmission shafts with opposite rotating directions are converted from one engine through one gear box to drive the two propellers to rotate, the two propellers can independently tilt forwards or backwards, and two motors are used for controlling and fixing the tilting directions and angles of the cross-shaped annular track and the propellers respectively. Rollers are mounted at the tail ends of the blades, and roll and rotate along the lower part of the cross-shaped annular track; the two cross-shaped annular rails are symmetrically hung below the two sides of the supporting frame, and the axes of the two horizontal transmission shafts are the same as the deflection axes of the cross-shaped annular rails. The device is suitable for helicopters and unmanned aerial vehicles.
一种单发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:如何给螺旋桨桨叶安装防护装置、设置左右对称的双螺旋桨倾转翼结构、使驾驶直升机更容易。技术方案要点是:采用左、右对称的两个螺旋桨布局,旋转方向相反;一台发动机通过一个齿轮箱转换出两个旋转方向相反的水平传动轴,带动两个螺旋桨旋转,两个螺旋桨均可独立地向前或向后倾转,使用两个马达分别控制和固定十字环形轨道和螺旋桨的倾转方向和角度;给桨叶末端安装滚轮,滚轮沿着十字环形轨道下方滚动、旋转;两个十字环形轨道对称悬挂在支撑架两侧下方,两个水平传动轴的轴线与十字环形轨道的偏转轴线相同。该装置适用于直升机和无人机。
