摘  要
按照傳統(tǒng)時間表的維護系統(tǒng)是耗錢、耗力的，并且只能給出不全面的對發(fā)動機故障的檢測和診斷?，F(xiàn)代飛機發(fā)動機的監(jiān)控和診斷系統(tǒng)具有讓維護人員獲得關于探測和診斷發(fā)動機故障的有價值信息的能力。在本文中，討論現(xiàn)代航空發(fā)動機監(jiān)控系統(tǒng)和故障診斷系統(tǒng)的組成，功能，以及相關的監(jiān)控和分析參數(shù)。討論的航空發(fā)動機滑油分析系統(tǒng)的原理與構成。最后，通過CFM56-3C滑油碎屑分析作為實例，闡述了發(fā)動機滑油分析的具體步驟和結論，為發(fā)動機的監(jiān)控趨勢分析提供了理論依據(jù)。 

關鍵詞：航空發(fā)動機；狀態(tài)監(jiān)控、故障診斷、滑油分析

Abstract
Traditional scheduled maintenance systems are costly, labor-intensive,and typically provid noncomprehensive detection and diagnosis of engine faults. The engine monitoring and dignosisi systemon modern aircrafts has the potential toprovid maintenanc person with valuable information for detecting and diagnosing engine faults. In this paper, modern aero-engine monitoring system and fault diagnosis system was dicussed and the oil diagnosis practice in line flight was been investiged. At last, CFM56-3C engine oil fielter and detonation was examed to provide the proofe for engine trend monitoring.

Keywords: aero-engine; monitoring; engine trend analysis; fault dignosis
