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. 反推装置有两个套筒

3、组件。两个套筒有一个支撑结构，支撑结构连接到滑块导轨，阻流门，拉杆，消音板组件，以及外函道板组件。套筒组件没有液压驱动的次级部件。3Description /描述描述 The acoustic panel assemblies and the blocker door assemblies are made of honeycomb composite materials. 消音板组件和阻流门组件为蜂窝复合材料， Blocker door阻流门阻流门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. 反推装置（TR）系统控制风扇叶片气流的排气方向从而实现正推力和反推力。5Operation /运作运作 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. 反推装置的套筒组件位于发动机的尾部。反推装置启动时，套筒

6、移到尾部，促使阻流门移动，封锁风扇函道及反推套筒组件的气流流动，使其从叶栅叶片中排出。气流从叶栅叶片中排出导致气流向前，从而产生反推力。6Thrust reverser assembly反推装置组件反推装置组件Thrust reverser assembly反推装置组件反推装置组件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. 反推装置系统

7、是由左右两侧反推装置悬挂在发动机支架舱上组合而成。锁扣及内侧V形装置把两个反推装置连结起来。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. 反推装置主要设计成一个滑动整流罩和叶栅。每个反推装置左右各有有一个滑动的外壁（整流罩）。这两个滑动整流罩在每个发动机上同时工作。然而，两个滑动整流罩是彼此独立的。8 Main components of each thrust reverser half 每个反推装置有以下主要部件每个反推装置有以下主要部件 Translating Sleeve 滑动整流罩 Inner Wall 内夹芯 3 Hydraulic actuators and 2 sync shafts 3个液压作动筒和2根同步轴 6 Cascades 6块叶栅 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. 当反推装置整流罩在向前（收缩）位置时，气流经风扇函道并从风扇函道后端排出。这就产生向前推力。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. 当反推装置整流罩移到尾部（伸展）位置，阻流门支杆

13、移动阻流门进入风扇管道，封锁风扇函道使气流不能进入，接着气流经叶栅组件排出。这些组件使气流反转，让气体由反推装置前部排出，这就产生反推力。11reLeft TR sleeve左侧反推整流罩左侧反推整流罩Cascade segments(6 per /half TR)叶栅（叶栅（ 6只只/一侧反推装置）一侧反推装置）Blocker doors(5 per /half TR)阻流门（阻流门（5只只/一侧反推装置）一侧反推装置）Blocker door Drag links(5 per /half TR)阻流门拉杆（阻流门拉杆（5只只/一侧反推装置）一侧反推装置）12Thrust Reverser
