The invention discloses an upper rotor wing control assembly and an upper rotor wing, belongs to the technical field of helicopters, and solves the problems that in the prior art, an upper rotor wing control structure of a coaxial helicopter is complex, gaps are large due to many kinematic pairs, and rigidity is reduced due to too many rod structures. The upper rotor control assembly is located below an upper rotor and a lower rotor of the helicopter, and the upper rotor is controlled from the lower portion of the upper rotor. The upper rotor control assembly comprises a fixed disc, a movable disc, a connecting rod assembly and a connecting shaft; the connecting shaft is of a hollow structure, one end of the connecting rod assembly is rotationally connected with the movable disc, and the other end of the connecting rod assembly penetrates through the connecting shaft to be rotationally connected with a paddle clamp of the upper rotor. The fixed disc is rotationally connected with the movable disc, the fixed disc comprises an x-axis rod and a y-axis rod vertically and fixedly connected with the x-axis rod, and the movable disc moves along the x axis and the y axis of the upper rotor to drive the movable disc to incline so as to realize periodic pitch change of the upper rotor. The upper rotor control assembly and the upper rotor can be used for helicopters.
本发明公开了一种上旋翼操纵组件和上旋翼,属于直升机技术领域,解决了现有技术中共轴直升机上旋翼操纵结构复杂、运动副较多导致间隙大以及杆类结构过多导致刚度下降的问题。该上旋翼操纵组件位于直升机的上旋翼和下旋翼的下方,从上旋翼的下方操纵上旋翼;上旋翼操纵组件包括定盘、动盘、连杆组件和连接轴;连接轴为中空结构,连杆组件的一端与动盘转动连接,连杆组件的另一端穿过连接轴与上旋翼的桨夹转动连接;定盘与动盘转动连接,定盘包括x轴杆以及与x轴杆垂直固定连接的y向杆,动盘沿上旋翼的x轴和y轴移动驱动动盘倾斜实现上旋翼的周期变距。该上旋翼操纵组件和上旋翼可用于直升机。
