CFM56-7B液压系统路径模拟研究摘要CFM56-7B发动机作为B737NG（Boeing737Next-Generation）单通道客机的专用发动机，是商业航空最受欢迎的发动机-飞机组合。为了对CFM56-7B发动机燃油系统的工作原理更加深刻直观的学习，以CFM56-7B发动机机型为研究对象，利用CATIA软件构造CFM56-7B发动机燃油系统的三维模型，并利用会声会影软件做成动画，对燃油系统进行模拟仿真。首先介绍了航空发动机燃油系统的发展简史；而后详细的分析CFM56-7B发动机燃油系统各部件的工作原理，以此为基础研究燃油系统的工作原理（各部件如何协调工作）；最后，对模拟仿真的过程简单的介绍并对毕业设计进行总结。关键词：航空发动机；燃油系统；模拟仿真；工作原理；CFM56-7BAbstractAsB737NG(Boeing737Next-Generation)single-channelaircraftdedicatedengine,CFM56-7Bengineisthemostpopularcommercialaviationengine-aircraftcombination.InordertostudytheworkingprincipleofCFM56-7Benginefuelsystem,CATIAsoftwareisusedtobuildCFM56engine’s3Dmodel.AndtheCorelVideoStudioX10softwareisusedtocreateanimationtoachievethesimulationofthefuelsystem.Firstly,thehistoryofthedevelopmentofaero-enginefuelsystemisintroducedatthefirstchapter.Then,thereistheworkingprincipleofeachcomponentofCFM56-7Benginefuelsystem,andtheworkingprincipleoffuelsystemisintroducedonthebasisofthechapter.Finally,simulationprocessesisintroducedsimplyandthesummaryofthegraduationpaperisincluded.KeyWords:Aero-engine;Fuelsystem;Simulation;Workingprinciple,CFM56-7B目录第一章绪论....................................................................................................................11.1CFM56的发展历史.................................................................................................11.2研究工作的目的、意义及应用领域......................................................................11.3研究方法、技术问题与预期成果..........................................................................2第2章CFM56-7B发动机液压系统.................................................................................32.2.1燃油分配系统................................................................................................42.2.2燃油控制系统................................................................................................42.2.3燃油指示系统................................................................................................42.3CFM56-7B发动机燃油系统及其各部件的工作原理...........................................52.3.1燃油泵组件....................................................................................................62.3.2整体驱动发电机（IDG）滑油冷却器.........................................................92.3.3伺服燃油加热器..........................................................................................102.3.4液压机械组件（HMU）.............................................................................112.3.5燃油/滑油热交换器.....................................................................................132.3.6燃油流量传感器..........................................................................................132.3.7燃油喷嘴油滤..............................................................................................142.3.8燃油分级活门（BSV）..............................................................................152.3.9燃油总管和燃油喷嘴..................................................................................172.4CFM56-7B燃油系统工...
