软管的缺点：流阻损失大航空软管常用于强烈振动或挠度大的地方连接运动部件和静止部件，也用于金属管道与软管之间的连接（Temporaryrepair）管路知识介绍•橡胶软管四层缠绕钢丝加固加固层保护蒙皮内管管路知识介绍橡胶软管两层棉编织带双金属丝编织带合成内管道合成内管道单金属丝编织带防火、抗滑油软管飞机管路的识别飞机管路系统的标志识别分为两种–第一种英文标记的识别TOXIC(有毒)PHPAN(危险)FLAM(易燃)PRESSURE(压力)RETURN(回油)DRAIN(排泄)红色易燃管路FLAM燃油FUEL飞机管路的识别•第二种彩带或印花燃油滑油液压油氧气水管压缩气体供水管排污管防火气源管空调除冰管路接头介绍按接头分类：(refermanual)–喇叭口接头（AN、AC）–非喇叭口接头（MS）BACS13BXFlarelessSleevesBACS13APFlarelessSleevesCRYOLIVEFlarelessSleeveBACC42WH-Coupling3P02111or3PHS111CryofitCouplingPermaswageFittingsRynglokUnion接头的类型Therearetwotypesofconnections:•-permanentconnections(permaswage).•-removableconnections(standardstraightorspecialfittings).LubricationthethreadsApplythethreadcompoundthatisapplicabletothesystem.Fullyapplythethreadcompoundto•theexternalthreads•shoulder•andconicalsealsurfaceoftheflarelesssleeveimmediatelybeforeinstallationNOTE:Donotgetthreadcompoundintheinternalpartofthetubeorintheboreofthefitting.Donotapplythreadcompoundwhenyouassemblethedri-lubedB-nuts.管路接头介绍管路接头介绍•无喇叭口管接头封严（MS）–装有锥形衬套的管子插入端接头组件中，管子前端面与管接头内沟槽接合，实现第一次封严。

–锥形衬套与接头组件内表面紧密贴合实现第二次封严–锥形衬套上的凸台与接头端面紧密贴合，实现第三次封严管路接头介绍•AC(AirCorpStandard)和AN(AirForce-NavyAeronauticalStandard)喇叭口接头的差别37度退刀槽35度管路接头介绍•AN(空海军标准接头)喇叭口接头管子平管嘴外套螺母管路接头介绍•喇叭口管接头封严–插入式端接头：有一锥面与喇叭口内表面紧密贴合–衬套筒：在喇叭口外面，支撑管子，防止喇叭口边缘的振动–螺帽：套在套筒外，上紧时带动喇叭口和套筒，使喇叭口紧贴在接头上，实现封严管路接头介绍1.弯管接头2.锁紧螺帽3.封圈保持环4.预成形封圈喇叭口与非喇叭口弯接头管路知识介绍小结•飞机有那些系统管路？•管路接头有那些种类？你能区分AN、AC、MS接头吗？•你能通过彩带标识识别系统吗？•管路按材料分类，硬管有那些？管路接头的制作与测试•管道的预加工•金属管路的弯曲•管路端头加工•渗漏校验管路接头的制作与测试•管道的预加工包括除油、下料和去毛刺–除油：就是除去管材内、外表面的油封油和油脂–下料：根据需要从一根长管取下适当的长度下料可单根、多根或批量。

常用下料的方法有切管器、手据、车床、铣床等管路接头的制作与测试切管器的正确使用管子的切断管路接头的制作与测试–去毛刺：手工、机械方法如：锉刀、刮刀等工具注意：无论用哪种方法去毛刺，都应保证管端内外辟有圆滑过度，以防止在加工时管端出现裂纹管路的制作加工管路接头的制作与测试内旋转式铰刀去毛刺管路的制作加工管路接头的制作与测试指示标记卡子半径块滑杆弯管的步骤1、向上提起滑杆2、放置管子。
