An air inlet air door device of an airplane auxiliary power system comprises an air inlet air door, an air outlet air door and an air outlet air door, wherein the air inlet air door can open and close an air inlet in a cabin wall of the airplane auxiliary power system; and the actuator is arranged on the bulkhead and is used for driving the air inlet air door. The air inlet air door device further comprises a pair of guide rails, the guide rails are installed on the bulkhead and slidably bear the two opposite sides of the air inlet air door, the actuator is arranged to drive the air inlet air door to linearly move between a first position and a second position, in the first position, the air inlet air door completely closes the air inlet, and in the second position, the air inlet is completely opened. The air inlet air door device can be small in size and weight, and the energy consumption of the airplane can be reduced by reducing the flight resistance.

    一种飞机辅助动力系统的进气风门装置包括:进气风门,该进气风门能够打开和关闭飞机辅助动力系统的舱壁上的进气口;以及,作动器,该作动器安装在舱壁上,并驱动进气风门。其中,进气风门装置还包括一对导轨,导轨安装在舱壁上,并可滑动地承载进气风门的相对两侧,且其中,作动器设置成驱动进气风门在第一位置和第二位置之间线性运动,在第一位置,进气风门将进气口完全关闭,在第二位置,进气口完全打开。该进气风门装置能够具有较小的体积和重量,并且还能通过降低飞行阻力节省飞机能耗。
