The invention relates to an air intake system of an auxiliary power plant, comprising: an air intake damper attached to a fuselage of an aircraft and rotatable between a damper open position and a damper closed position; the air inlet channel is arranged at the downstream of the air inlet air door so as to guide air entering through the air inlet air door to an air inlet component of the auxiliary power device; the separation channel is arranged in front of the air inlet air door along a fuselage of the aircraft and can move between a separation channel opening position and a separation channel closing position; the cooling pipe is arranged at the downstream of the separation channel so as to guide air entering through the separation channel to a cooling component of the auxiliary power device; and the actuating device is attached to the air inlet air door and the separation channel so as to control opening and closing of the air inlet air door and the separation channel. By arranging the separation channel, the influence of an incoming flow boundary layer on the air inlet system can be effectively isolated, so that the air inlet quality is improved, and the working efficiency of the APU is further improved. In addition, the invention further relates to an auxiliary power device.

    本发明涉及一种辅助动力装置的进气系统,包括:进气风门,进气风门附连到飞行器的机身并且能在风门打开位置和风门闭合位置之间转动;进气道,进气道设置在进气风门下游,以将经由进气风门进入的空气引导到辅助动力装置的进气部件;隔道,隔道沿着飞行器的机身设置在进气风门前方,并且能在隔道打开位置和隔道闭合位置之间移动;冷却管,冷却管设置在隔道下游,以将经由隔道进入的空气引导到辅助动力装置的冷却部件;以及作动装置,作动装置附连到进气风门和隔道,以控制进气风门和隔道的打开和闭合。通过设置隔道,能够有效隔绝来流边界层对于进气系统的影响,从而提高进气品质,进一步改善APU做功效率。另外,本发明还涉及一种辅助动力装置。
