A set of free rotors are mounted on a wing tip of a driving rotor on a helicopter body, when the driving rotor applies power to rotate, the free rotors on the wing tip are made to rotate in the opposite direction under the action of air resistance, the free rotors rotate to balance the working state that the wing root and the wing tip of the driving rotor cannot cut air at the same speed, and efficiency is improved; as the free rotors rotate in the direction opposite to that of the driving rotor, the linear speed of the wing tip of the outermost rotor is reduced, the noise is reduced, and theefficiency is also improved.
在直升机机身上主动旋翼翼尖安装一组自由旋翼,当主动旋翼施加动力旋转的时候,在空气阻力的作用下使翼尖上自由旋翼向相反的方向旋转,自由旋翼旋转均衡主动旋翼翼根和翼尖不能同速切割空气的工作状态,提高了效率,由于自由旋翼是与主动旋翼相反方向旋转,降低了最外围旋翼翼尖的线性速度,降低了噪音也提高了效率。
