摘　　要：APU进气风门作动器的选择正确与否,直接关系到作动器能否在各种工况下打开、关闭APU进气风门,甚至影响整个飞机的正常运营。从APU进气风门气动力矩和破冰力矩的角度出发,分别给出两种不同的作动器选型标准,对比分析这两种标准,给出了APU进气风门作动器的初步选型方法。Whether the APU inlet duct actuator is chosen correctly or not is directly related to whether the actuator can open or close inlet door under various operating conditions, and could even affect the normal operations of the aircraft. This research proposes two selection criteria for inlet duct actuator based on APU inlet door aerodynamic torque and ice breakout torque respectively, and then proposes a preliminary method of selection for inlet duct actuator according to the analysis result of the two selection criteria.
