The invention discloses a manipulator for an upper rotor wing and the upper rotor wing, belongs to the technical field of helicopters, and solves the problems that in the prior art, a coaxial helicopter upper rotor wing control structure is complex, gaps are large due to many kinematic pairs, and rigidity is reduced due to too many rod structures. The manipulator is located above an upper rotor wing of the helicopter, and the upper rotor wing is manipulated from the upper portion of the upper rotor wing. The manipulator comprises a fixed disc, a movable disc, a guide steering engine, a variable-pitch pull rod and a variable-pitch rocker arm, one end of the fixed disc is rotationally connected with an output shaft of the guide steering engine, the other end of the fixed disc is rotationally connected with the movable disc, one end of the variable-pitch pull rod is rotationally connected with the movable disc, and the other end of the variable-pitch pull rod is rotationally connected with one end of the variable-pitch rocker arm; and the other end of the variable pitch rocker arm is fixedly connected with one side of the paddle clamp. The manipulator and the upper rotor can be used for helicopters.
本发明公开了一种用于上旋翼的操纵器以及上旋翼,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。该操纵器位于直升机上旋翼的上方,从上旋翼的上方操纵上旋翼;操纵器包括定盘、动盘、导向舵机、变距拉杆和变距摇臂,定盘的一端与导向舵机的输出轴转动连接,定盘的另一端与动盘转动连接,变距拉杆的一端与动盘转动连接,变距拉杆的另一端与变距摇臂的一端转动连接,变距摇臂的另一端与桨夹的一侧固定连接。该操纵器以及上旋翼可用于直升机。
