The invention provides an empennage control mechanism with a variable transmission angle, and relates to the field of aviation. Comprising a tilting large shaft, a tilting rocker arm, a cross-shaped control rocker arm, a Y-shaped adapter frame, a tilting actuator cylinder and a deflection actuator cylinder. The tilting large shaft is supported on the front machine body frame and the rear machine body frame, and the tilting large shaft is fixedly connected with the starting end of the tilting rocker arm. And the tilting large shaft and the tilting rocker arm are driven by the tilting actuating cylinder to rotate around the tilting axis of the empennage. The deflection actuating cylinder is connected with a cross-shaped control rocker arm, and the cross-shaped control rocker arm is rotationally connected with a support fixed on the machine body frame and can rotate around a rocker arm shaft of the cross-shaped control rocker arm. And the cross-shaped control rocker arm is hinged with the Y-shaped adapter frame through a connecting shaft. The Y-shaped transfer frame is connected to the empennage through hinge points on the empennage main beam and the tail beam partition plate.
本发明提供一种变传动角的尾翼操纵机构,涉及航空领域。包括倾转大轴、倾转摇臂、十字操纵摇臂、Y形转接架、倾转作动筒、偏转作动筒。倾转大轴支撑在前后两个机身框上,倾转大轴与倾转摇臂始端固定连接在一起。倾转大轴和倾转摇臂在倾转作动筒的驱动下,绕尾翼倾转轴线转动。偏转作动筒与十字操纵摇臂相连,十字操纵摇臂与固定在机身框上的支座转动连接,能够绕十字操纵摇臂的摇臂轴转动。十字操纵摇臂与Y形转接架通过连接轴铰接在一起。Y形转接架通过尾翼主梁上和尾梁隔板上的铰接点连接到尾翼上。
