1、CFM56-3 發(fā)動(dòng)機(jī)航線常見故障分析 發(fā)動(dòng)機(jī)航線常見故障分析 摘要 摘要本文從風(fēng)扇單元體、核心發(fā)動(dòng)機(jī)單元體、低壓渦輪單元體、附件齒輪箱單元體幾方面簡單介紹了 CFM56-3 發(fā)動(dòng)機(jī)基本構(gòu)造，闡述了 CFM56-3 發(fā)動(dòng)機(jī)的主要技術(shù)性能參數(shù)。針對(duì) CFM56-3 發(fā)動(dòng)機(jī)在航線運(yùn)行使用過程中出現(xiàn)的一些常見故障：油門桿錯(cuò)位、發(fā)動(dòng)機(jī)起動(dòng)不成功、反推故障和發(fā)動(dòng)機(jī)起動(dòng)過程中 EGT 數(shù)字閃爍等常見故障，結(jié)合東方航空云南分公司自 1985 年以來在

2、實(shí)際維護(hù)使用過程中的排故經(jīng)驗(yàn)，從故障現(xiàn)象、工作原理分析和排故過程幾個(gè)方面進(jìn)行了詳細(xì)的總結(jié)和分析，并提出了自己的觀點(diǎn)。對(duì) CFM56-3 發(fā)動(dòng)機(jī)的排故和維護(hù)具有一定指導(dǎo)意義。關(guān)鍵詞： 關(guān)鍵詞： CFM56-3 發(fā)動(dòng)機(jī) 油門桿錯(cuò)位 起動(dòng)不成功 反推故障 起動(dòng)過程中 EGT 數(shù)字閃爍Abstract:The thesis describes the basic engine structure, performance feat
