The invention discloses an APU air inlet air door system. The length of an air inlet air door can be increased on the basis that an opening of an aircraft skin is not changed. The APU air inlet air door system comprises an air channel, an air inlet and an air outlet, the air inlet air door is used for opening or closing the air channel; the air inlet air door comprises an air door fixed section and an air door moving section capable of stretching out and drawing back relative to the air door fixed section, and when the air inlet air door is closed, the air door moving section can stretch out and draw back relative to the air door fixed section. When the air inlet air door is opened, the actuator enables the air door moving section to retract relative to the air door fixed section so as to shorten the overall length of the air inlet air door, and when the air inlet air door is opened, the actuator enables the air door moving section to extend relative to the air door fixed section so as to increase the overall length of the air inlet air door.
一种APU进气风门系统,能够在不改变飞机蒙皮的开口的基础上增加进气风门的长度。本发明的APU进气风门系统,包括:气道;使所述气道打开或关闭的进气风门;以及使所述进气风门打开或关闭的作动器,其中,所述进气风门包括风门固定段和能够相对于所述风门固定段伸缩的风门移动段,在所述进气风门关闭时,所述作动器使所述风门移动段相对于所述风门固定段缩回而缩短所述进气风门整体的长度,在所述进气风门打开时,所述作动器使所述风门移动段相对于所述风门固定段伸出而增加所述进气风门整体的长度。
