The invention discloses a double-propeller 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 so as to enable the helicopter to be more easily piloted. According to the technical scheme, an engine is used for driving two propellers to rotate to provide lift force for the helicopter, the two propellers are the same in rotation diameter, bilaterally symmetrical and opposite in rotation direction, torsional moments are offset, and the flight height is controlled by the size of an accelerator; the wind pendulums are installed below the blades, the wind pendulums are connected in series through the connecting rods, the two motors control the wind pendulums to deflect forwards or backwards in the direction and angle, the thrust of the two sides of the helicopter body is adjusted, the helicopter is driven to turn left, turn right, fly forwards and fly reversely, the larger the accelerator is, and the larger the backward deflection angle of the wind pendulums is, the higher the flight speed is. And the upper ends of the two transmission shafts are provided with gears, and the rollers roll and rotate along the lower parts of the rails. The method is suitable for helicopters and unmanned aerial vehicles.

    一种单发直升机的双螺旋桨装置,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、使驾驶直升机更容易。技术方案要点是:使用一台发动机带动两个螺旋桨旋转为直升机提供升力,两个螺旋桨旋直径相同、左右对称、转方向相反,扭力矩相互抵消,油门大小控制飞行高度;风摆安装在桨叶下方,连杆将多个风摆串联起来,两个电机控制风摆向前或向后偏转方向和角度,调整机身两侧推力的大小,驾驶直升机左转弯、右转弯、向前飞、倒飞,油门越大和风摆向后偏转角度越大,飞行速度就越大。两个传动轴下端安装转盘、桨叶和滚轮,上端安装齿轮,滚轮沿轨道下方滚动、旋转。该发明适用于直升机和无人机。
