According to the air door actuating system, an actuator does not need to rotate, and the fireproof requirement can be reliably met in a simple metal connection mode. The air door actuation system (100) comprises an air door (110) and an actuator (130), the air door is arranged at an opening of an air inlet channel (300) of an aircraft outer skin (200), when an auxiliary power device works, the actuator (130) drives the air door to open the air inlet channel, and otherwise, the actuator enables the air door to be in a state of closing the air inlet channel. A sliding structure (120) is arranged between the air door and the actuator, and the actuator penetrates through an opening of an air inlet channel wall (310) of the air inlet channel to act on the air door. And the air door is opened or closed by utilizing the synchronization of the linear motion of the actuator and the rotary motion and the linear motion of the sliding structure.
一种风门作动系统,其中的作动器无需转动,能以简单的金属连接方式可靠地满足防火要求。该风门作动系统(100)包括风门(110)和作动器(130),所述风门设置在飞机外蒙皮(200)的进气道(300)开口处,当辅助动力装置工作时,所述作动器(130)带动所述风门打开所述进气道,反之,所述作动器使所述风门处于将所述进气道关闭的状态,其特征是,在所述风门与所述作动器之间设置有滑动结构(120),所述作动器穿过所述进气道的进气道壁(310)的开口作用于所述风门上,在所述风门打开或关闭过程中,利用所述作动器的直线运动与所述滑动结构的旋转运动和直线运动同步来实现所述风门打开或关闭。
