Height 90 inches 高- 90英寸 D. Weight 346 pounds 重 346磅2Description /描述描述 The thrust reverser has two sleeve a

2、ssemblies. The sleeves have a supporting diaphram structure. The supporting diaphram structure is attached to the slider guides, the blocker doors, drag links, the acoustic panel assemblies, and the outer cowl panel assemblies. The sleeve assemblies have no hydraulic powered subcomponents. 反推裝置有兩個套筒

3、組件。兩個套筒有一個支撐結(jié)構(gòu)，支撐結(jié)構(gòu)連接到滑塊導(dǎo)軌，阻流門，拉桿，消音板組件，以及外函道板組件。套筒組件沒有液壓驅(qū)動的次級部件。3Description /描述描述 The acoustic panel assemblies and the blocker door assemblies are made of honeycomb composite materials. 消音板組件和阻流門組件為蜂窩復(fù)合材料， Blocker door阻流門阻流門4Function/功能功能 The thrust reverser (T/R) system controls the direction of

4、 the fan air exhaust to make forward or reverse thrust. 反推裝置（TR）系統(tǒng)控制風(fēng)扇葉片氣流的排氣方向從而實現(xiàn)正推力和反推力。5Operation /運作運作 The thrust reverser sleeve assemblies are located on the aft part of the engine. They are stowed in a forward position during flight. When the thrust reverser is actuated, the sleeves move to

5、the aft. This moves the blocker doors to block the flow of air between the fan duct assembly and the thrust reverser sleeve assemblies, then exposes the cascade vanes. The air then flows out through the cascade vanes which direct the air forward to create reverse thrust. 反推裝置的套筒組件位于發(fā)動機的尾部。反推裝置啟動時，套筒

6、移到尾部，促使阻流門移動，封鎖風(fēng)扇函道及反推套筒組件的氣流流動，使其從葉柵葉片中排出。氣流從葉柵葉片中排出導(dǎo)致氣流向前，從而產(chǎn)生反推力。6Thrust reverser assembly反推裝置組件反推裝置組件Thrust reverser assembly反推裝置組件反推裝置組件7General/概述概述The T/R system uses left and right T/R halves that attach to the engine strut. Tension latches and inner V-blades hold the halves together. 反推裝置系統(tǒng)

7、是由左右兩側(cè)反推裝置懸掛在發(fā)動機支架艙上組合而成。鎖扣及內(nèi)側(cè)V形裝置把兩個反推裝置連結(jié)起來。Thrust reverser is a translating sleeve and cascade design. Each thrust reverser has a wall with a translating sleeve of the left and right half of the ducted fan. The two sleeves on each engine work simultaneously. However, the two sleeves are independe

8、nt of each other. 反推裝置主要設(shè)計成一個滑動整流罩和葉柵。每個反推裝置左右各有有一個滑動的外壁（整流罩）。這兩個滑動整流罩在每個發(fā)動機上同時工作。然而，兩個滑動整流罩是彼此獨立的。8 Main components of each thrust reverser half 每個反推裝置有以下主要部件每個反推裝置有以下主要部件 Translating Sleeve 滑動整流罩 Inner Wall 內(nèi)夾芯 3 Hydraulic actuators and 2 sync shafts 3個液壓作動筒和2根同步軸 6 Cascades 6塊葉柵 5 Blocker doors 5

11、cted) position, the fan air exhaust goes through the fan duct and comes out at the rear of the fan duct. This makes forward thrust. 當(dāng)反推裝置整流罩在向前（收縮）位置時，氣流經(jīng)風(fēng)扇函道并從風(fēng)扇函道后端排出。這就產(chǎn)生向前推力。When the T/R sleeves move to the aft (extended) position, the blocker door drag links move the blocker doors into the fan

12、duct. This causes a blockage of the fan air exhaust in the fan duct. The fan air then flows through the cascade segments. The segments turn the fan air exhaust. They cause the fan air exhaust to come out the sides of the T/R in a forward direction. This makes reverse thrust. 當(dāng)反推裝置整流罩移到尾部（伸展）位置，阻流門支桿

13、移動阻流門進入風(fēng)扇管道，封鎖風(fēng)扇函道使氣流不能進入，接著氣流經(jīng)葉柵組件排出。這些組件使氣流反轉(zhuǎn)，讓氣體由反推裝置前部排出，這就產(chǎn)生反推力。11reLeft TR sleeve左側(cè)反推整流罩左側(cè)反推整流罩Cascade segments(6 per /half TR)葉柵（葉柵（ 6只只/一側(cè)反推裝置）一側(cè)反推裝置）Blocker doors(5 per /half TR)阻流門（阻流門（5只只/一側(cè)反推裝置）一側(cè)反推裝置）Blocker door Drag links(5 per /half TR)阻流門拉桿（阻流門拉桿（5只只/一側(cè)反推裝置）一側(cè)反推裝置）12Thrust Reverser
