The invention belongs to the field of structural design of high-speed helicopters, and discloses a control surface control mechanism of a high-speed helicopter. The mechanism is composed of two sets of hinge joints, a cross coupling assembly, a steering engine rocker arm, a torque transmission shaft, a knuckle bearing, a bush, a bolt and the like, the two sets of hinge joints are each composed ofa double-lug joint and a single-lug joint and are installed on a high-speed helicopter body and a control plane, and the axes of the two sets of hinge joints are collinear. And in the two groups of hinge joints, the gap between the single-lug joint and the double-lug joint of one group of hinge joints is 0, and the gap between the single-lug joint and the double-lug joint of the other group of hinge joints is greater than 0. The control surface can rotate around the fixed axis, the motion space of the control mechanism is reduced, the integrity of the appearance of the high-speed helicopter isguaranteed, and therefore the flight resistance of the high-speed helicopter is reduced.

    本发明属于高速直升机结构设计领域,公开了一种高速直升机舵面操纵机构。本发明由两组铰链接头、十字联轴节组件、舵机摇臂、扭矩传动轴、关节轴承、衬套、螺栓等组成,其中所述两组铰链接头分别由一个双耳接头及一个单耳接头组成,且分别安装于高速直升机本体与舵面上,且两组铰链接头的轴线共线。所述两组铰链接头,其中一组铰链接头的单耳接头与双耳接头的间隙为0,另一组铰链接头的单耳接头与双耳接头的间隙大于0。不仅实现了舵面绕固定轴线的转动,又降低了操纵机构的运动空间,保证了高速直升机外形的完整性,从而降低了高速直升机飞行阻力。
