The invention discloses a linkage mechanism, and relates to the field of aircraft design. The linkage mechanism comprises a flight control cabin, an air rudder rotationally connected to the flight control cabin through an air rudder rotating shaft, a gas rudder cabin ring fixedly connected to the tail end of the flight control cabin and a gas rudder rotationally connected to the gas rudder cabin ring through a gas rudder rotating shaft, and a rocker arm is fixedly connected to the gas rudder rotating shaft; a connecting rod is rotationally connected to the gas rudder cabin ring, a sliding block is rotationally connected to the rocker arm, and the sliding block is slidably connected to the connecting rod. And a rotor is arranged on the air rudder and is connected to the connecting rod in a sliding manner. The linkage mechanism is designed in a limited space, torque for driving the air rudder to deflect can be transmitted to the gas rudder surface when the aircraft is at an initial low flight speed, so that the air rudder and the gas rudder synchronously deflect at the same angle, high-temperature and high-speed gas flow of an engine acts on the gas rudder surface to generate enough torque, and the air rudder and the gas rudder are driven to deflect synchronously. Therefore, aircraft attitude control requirements are met.

    本发明公开一种联动机构,涉及飞行器设计领域。该联动机构包括飞行控制舱、通过空气舵转轴转动连接在飞行控制舱上的空气舵、固定连接在飞行控制舱尾端的燃气舵舱环和通过燃气舵转轴转动连接在燃气舵舱环上的燃气舵,燃气舵转轴上固定连接有摇臂;燃气舵舱环上转动连接有连杆,摇臂上转动连接有滑块,滑块滑动连接在连杆上;空气舵上设有转子,转子滑动连接在连杆上。该联动机构在有限空间内设计联动机构,可以在飞行器初始低飞行速度时,将驱动空气舵偏转的力矩传递到燃气舵面上,使空气舵和燃气舵同步同角度偏转,发动机高温高速燃气流作用在燃气舵面产生足够力矩,以满足飞行器姿态控制要求。
