SYSTEM OVERVIEW 系统回顾
The CFM56-5B engine is a dual-rotor, variable stator, high bypass ratio turbo fan power plant. The CFM56-5B powers the complete single aisle family of aircraft. CFM56-5B engines are available in several thrust ratings.
CFM56-5B 发动机是一个双转子，可变定子，高涵道比涡轮风扇式发动机。
CFM56-5B 发动机被安装在单通道家族飞机上。CFM56-5B 发动机有几种推力级可供使用。
All the engines are basically the same. A programming plug on the Electronic Control Unit (ECU) changes the available thrust.
所有的发动机基本上是相同的。在电子控制组件（ECU）上有一个程序设计销钉可改变现有的推力。
The power plant installation includes the engine, the engine inlet, the exhaust, the fan cowls and the reverser assemblies. The pylon connects the engine to the wing structure. The engine is attached to the pylon by forward and aft mounts.
动力装置包括发动机，发动机进气道，排气口，风扇包皮和反推装置。吊架将发动机连接到大翼结构上。发动机通过前后两个吊点与吊架连接。

SYSTEM OVERVIEW - THRUST REVERSER SYSTEM
系统概述-反推系统
Reverse thrust is controlled by the EEC. Reverse is manually selected by the flight crew by lifting the latching levers on the throttle control levers. The reverse thrust command is sent to the EEC and the EIU. The DEPLOY command from the EEC is routed through the EIU as a second level of protection against inadvertent deployment.
EEC 控制反推装置。反推可以由机组通过抬起推力控制手柄的锁定杆进行人工设置。反推信号传输到EEC 和EIU（Engine Interface Unit 发动机接口组件），来自EEC 得信号通过EIU 的二次确认，才得以实施反推动作。
SYSTEM OVERVIEW - THRUST REVERSER SYSTEM
系统概述-反推系统
According to commands from the EEC and the EIU, a Hydraulic Control Unit (HCU) supplies hydraulic power to operate the thrust reverser.The thrust reverser assembly has 2 hydraulically actuated translating sleeves. The translating sleeves are each powered by 2 actuators. As the translating sleeve moves aft during deployment, it raises blocker doors to redirect the engine fan airflow.
依据来自EEC 和EIU 的信号，液压控制装置（HCU）提供液压力操作反推。反推组件包含有两个液压的转换管路，转换管路给每边各两个作动筒提供压力。通过液压力来控制反推的收放。
