【正文】 中國民航飛行學(xué)院 本科生畢業(yè)設(shè)計(jì)(論文 ) 外來物對發(fā)動(dòng)機(jī)影響的分析 i 摘 要 文章研究地面滑行階段 以及飛行階段 影響航空發(fā)動(dòng)機(jī)安全的外界因素，結(jié)合航空發(fā)動(dòng)機(jī)慢車時(shí)吸入外來物的實(shí)例， 參考了國內(nèi)外出版的同類文獻(xiàn)及 最新的數(shù)據(jù) ,運(yùn)用模擬撞擊 的方法，分析了外來物對航空發(fā)動(dòng)機(jī)安全的影響。分析結(jié)果表明滑行道上的沙礫、小石塊、清潔布、手用工具、螺栓和螺釘?shù)任锛?、積冰天氣甚至鳥擊 都會(huì)成為發(fā)動(dòng)機(jī)的不安全因素，如果這些部件被發(fā)動(dòng)機(jī)吞咽，會(huì)嚴(yán)重威脅到發(fā)動(dòng)機(jī)的安全。對本課題的研究有助于以后的 飛行工作 ，培養(yǎng)良好的 飛行 作風(fēng)，樹立安 全意識，時(shí)刻保持清醒的頭腦注意發(fā)動(dòng)機(jī)的地面危險(xiǎn)區(qū)域，從根本上減少影響到發(fā)動(dòng)機(jī)安全的各種外界因素，保障發(fā)動(dòng)機(jī)穩(wěn)定、安全地工作 。 關(guān)鍵詞 :地面滑行 以及飛行階段 ；發(fā)動(dòng)機(jī)安全；撞擊；損傷ii ABSTRACT This essay make a study of the aircraft engine safety influenced by external factors at the ground taxiing and flight stage, bined with the instance that inhaled foreign objects when the engine idled, reference to similar document by domestic and foreign literature and the latest published data, use the simulated methods, analysis of the foreign objects affect to aircraft engine safety on the ground taxiing stage. The results show that gravel, small stones, cleaning cloth, hand tools, bolts and screws , aircraft icing angbird strike will bee unsafe factors of the engine, if these ponents are swallowed by the engine, they would seriously threat the safety of the engine. The investigation of this subject will be help of the flight in the future, to develop good style of the flight, establishing a sense of safety and keep clear of the head to be care of the ground danger area of the engine, reducing the various external factors which affect the safety of the engine to protect the engine stability and safety work。 Key words:ground taxiing and flight stage。 engine safe。 knock。 damage iii 目 錄 1 緒論 ................................................................................................................................... 1 課題研究的背景 ......................................................................................................... 1 課題研究的意義 ......................................................................................................... 1 飛行場地 ..................................................................................................................... 2 飛行階段 ..................................................................................................................... 2 地面滑行 ..................................................................................................................... 3 發(fā)動(dòng)機(jī)安全 ................................................................................................................. 3 2 發(fā)動(dòng)機(jī)吸入外物對發(fā)動(dòng)機(jī)安全的影響 ........................................................................... 4 發(fā)動(dòng)機(jī)合格證規(guī)范要求 ............................................................................................. 4 發(fā)動(dòng)機(jī)慢車的狀態(tài)及危險(xiǎn)性 ..................................................................................... 4 進(jìn)氣道和風(fēng)扇外來物沖擊損傷 ................................................................................. 4 進(jìn)氣道外來物沖擊損傷 ..................................................................................... 4 風(fēng)扇外來物沖擊損傷 ......................................................................................... 4 壓氣機(jī)葉片外物沖擊損傷 ......................................................................................... 5 3 地面滑行階段影響發(fā)動(dòng)機(jī)安全的外界因素 .........................................
