发动机及液压参数用发光二极管显示在两个发动机指示面板上。
发动机在中央面板上显示及控制包括以下内容：
·N1 显示—用转速百分比指示风扇转速
·N2 显示—用转速百分比指示高压压气机转速。
·排气温度指示
1. 用°C 指示排气温度。
2. 如果发动机超出红线，N1，N2 上方的红灯及发动机排气温度指示灯
亮。
·燃油流量指示
用每台发动机每小时总的消耗重量指示燃油量。
FUEL FLOW/FUEL USED 开关用于改变FUEL FLOW/FUEL USED 的
显示模式，10 秒后FUEL USED 显示恢复到FUEL FLOW。
·FUEL USED RESET—显示一个顺序：上次重置后上电后的燃油使用，
然后是000，最终燃油流量。
·发动机滑油压力指示—用PSI 指示发动机滑油压力。
·发动机滑油温度指示—用°C 指示发动机滑油温度。
·发动机滑油量指示—用百分比显示发动机滑油量。
·发动机振动值指示—显示发动机最大振动值。
·液压指示—用PSI 显示液压系统压力。
·液压油量显示—用百分比显示液压油量。

二、TEXT
(1) the auxiliary power unit (APU) is used for providing:
1) compressed air for engine starting.
2) Compressed air to the air conditining system on the ground or in flight.
3) Electrical power to the airplane electrical system on the ground or in
-flight ,(we will discuss APU electrical power in the next lesson).
辅助动力装置APU 被用于提供以下：
1) 为发动机起动提供压缩空气
2) 在地面或飞行中为空调系统提供压缩空气
3) 在地面或飞行中为飞机电源系统提供电源
(2) The APU engine is located in the aft end of the fuselage, behind the
pressure bulkhead and below the horizontal stabilizer. The APU engine is
completely enclosed in a titanium shroud. The air inlet door is located on
the right side of the aft fuselage for air entrance. The airflow is split into
two paths, one for the engine and the second for the accessories cooling.
The cooling air exhaust overboard through a hole in lower shroud. The
exhaust ducting is cooled by four air inlets around the jet pipe. Fuel is
supplied through a shrouded line from fuel tank. Bleed air from the APU
is supplied to the pneumatic system through a bleed valve, the bleed air
can be used to perate either of the two air —conditioning packs or for
main engine starting. The APU is readily accessible for inspection,
maintenance or removal through a large door in the fuselage directly
below it . removal is accomplished by lowering the assembly with a
simple hoist and cable system.
The APU is a singe shaft gas turbine engine with a two stage centrifugal
compressor, a single combustion chamber and one radial inflow turbine.
The accessories group, driven by the gear box , is at the front of the unit.
APU 发动机安装于机身尾部、压力隔板后面及水平安定面下方。APU
发动机被完全地封进一个钛防护罩中。空气进口安装于机身后部右
侧。进入APU 的空气被分成两个通路，一个供给发动机，另一个供
给容易接近的冷却器。冷却空气通过保护罩下方的一个孔排放出去。
排气管道被四个围绕喷射管道的进口空气冷却。燃油从燃油箱通过一
个带保护的管道提供。从APU 出来的引气通过一个引气阀门被提供
到增压系统，引气可以被用来控制两个空调组件中的任一个，也可用
于发动机起动。APU 通过它正下方机身的一个大的口盖很容易接近，
