摘　　要：飞机空调系统是航空器非常重要的一个系统,飞机空调系统故障直接影响航班正常运行,这给航空公司带来巨大的成本压力,因此研究飞机冲压空气全开灯亮故障故障是非常有必要的。为了分析飞机冲压空气全开灯亮的原因,通过对不同的故障现象进行分析,以波音维修手册维修方法为基础,结合空调系统冷却原理,建立了完整的基于各个故障现象排故方式。本文B737-800飞机冲压空气全开灯亮故障故障为例,根据故障现象给出了不同的排故方案:①短时出现冲压空气全开灯亮,根据空调冷却原理可知热交换器脏导致的;②在地面对空调附件组件(AUAC)进行测试,有故障代码的,根据故障代码进行排故;③AUAC无任何代码,是冲压空气排气单向活门故障引起的。实践证明,该方法可以有效的运用在B737-800飞机航线排故中。The aircraft air conditioning system is a very important system in aircraft,and the failure of the aircraft air conditioning system directly affects the normal operation of flights,which brings huge cost pressure to airlines.Therefore,it is necessary to study the fault of the aircraft ram air fully on light.In order to analyze the reasons for the full on light of the aircraft's stamping air,a complete troubleshooting method based on various fault phenomena was established based on the Boeing maintenance manual maintenance method and the cooling principle of the air conditioning system.As an example of the malfunction of the B737-800 aircraft's ram air fully on light,different troubleshooting solutions are provided based on the fault phenomenon:A:If the ram air fully on light is on for a short time,it can be inferred from the cooling principle of the air conditioning that the heat exchanger is dirty;B:Test the air conditioning accessory component(AUAC)on the ground.If there is a fault code,troubleshoot it according to the fault code;C:AUAC has no code and is caused by a malfunction of the ram air exhaust one-way valve.Practice has proven that this method can be effectively applied to the troubleshooting of B737-800 aircraft routes.
