The invention discloses a propeller of a helicopter and a control device of the propeller, belongs to the technical field of helicopter production, and aims to solve the technical problems that 1, how to enable the propeller to rotate along a certain track; 2, how to control the deflection of the propeller by adopting a swash plate structure; according to the technical scheme, a transmission shaft drives a turntable and a propeller to rotate, and a roller at the tail end of the propeller rolls below a track; the hydraulic control system controls the swash plate to descend, compresses the propeller deflection system and drives the propeller to deflect downwards to generate lift force; the hydraulic piston system is controlled to enable the plane of the swash plate to incline, and the small rollers roll and fluctuate up and down along the plane below the swash plate, so that the propeller has different deflection angles and different lift forces within a circle of rotation, the fuselage inclines and generates lateral power, and the inclined directions of the swash plate are different, so that the generated lateral power is different; the device is suitable for flight power and control devices of military and civil helicopters.

    一种直升机的螺旋桨及其控制装置,属于直升机生产技术领域,所要解决的技术问题:1.如何使螺旋桨沿一定的轨道旋转;2.如何采用倾斜盘结构控制螺旋桨的偏转。技术方案要点是:传动轴带动转盘、螺旋桨旋转,螺旋桨末端的滚轮沿轨道下方滚动;液压控制系统控制倾斜盘下降,压缩螺旋桨偏转系统,带动螺旋桨向下偏转,产生升力;控制液压活塞系统,使倾斜盘平面发生倾斜,小滚轮沿倾斜盘下方平面滚动,上下起伏,使螺旋桨在旋转一周内偏转角度不同,产生升力也不同,使机身倾斜并产生侧向动力,倾斜盘倾斜方向不同,产生的侧向动力不同;该装置适用军用、民用直升机的飞行动力和控制装置。
