摘　　要：飞机飞行过程中,通过对滤芯上污染物的收集、检测来监视飞机动力系统与传输系统中被油浸润的机械组件工作及磨损状态。收集到的微粒,污物,例如金属屑、炭化物和硅砂,会集中在“污染警报滤芯”的诊断层上。诊断层很容易移除,这样,在飞机的正常飞行及维护期间,通过更换滤芯,移除并检查诊断层,就可以及时获取相关组件磨损情况的信息。并且,还可以对检测层污染物进行进一步晶粒或光谱检查分析,判断污染物的成分,就可以分析发动机可能会出现的问题,并对相关组件进行有针对性的维护。During aircraft flight,the working and wear status of mechanical components soaked by oil in aircraft power system and transmission system are monitored through the collection and detection of pollutants on the filter element.The collected particles and dirt,such as metal chips,carbonization,and silica sand,will be concentrated on the diagnostic layer of the“pollution alarm filter element”.The diagnostic layer can be easily removed.In this way,during the normal flight and maintenance of the aircraft,the information on the wear of relevant components can be obtained in time by replacing the filter element,removing and inspecting the diagnostic layer.In addition,further grain or spectral inspection and analysis can be carried out on the pollutants in the detection layer to judge the composition of the pollutants,so as to analyze the possible problems of the engine and carry out targeted maintenance on relevant components.
