Question: Answers to the translations in Text A

Unit 5: Text B The Fuel System

Review☆

It consists of the fuel tanks, a fuel tank ventilation system, and a means to transfer fuel from tank to tank within the airplane. 它包括油箱，油箱通风系统、和一个可以将飞机内的燃油从一个油箱输送到另一个油箱的燃油泵。

All aircraft must load reserve fuel, but not all aircraft have dedicated tanks for it. 所有的飞机都必须装载备用燃油，但并不是所有的飞机为此而有专用的油箱。

Auxiliary fuel tanks are optional tanks installed in the cargo compartments to further increase the aircraft range. 副油箱是安装在货舱内可选用的油箱，以便进一步增加飞机的航程。

This arrangement of the refueling valves allows the replacement of the control components without emptying the tank and gives you easy access to operate the valve by manual override if necessary. 加油阀门这样的设置，无须排空油箱就可更换控制元件，如有必要，也可轻松的手动操控阀门。

1. How many fuel tanks are there on the airplane?


There are 3 tanks for fuel storage and 2 vent surge tanks for temporary fuel storage. Tank No.1 is located in the left wing, tank No. 2 is located in the right wing and center tank is located in the fuselage under the passenger cabin. The 2 vent surge are located outboard of the main tanks.

2. How is fueling accomplished?


The fueling system provides a means of filling the fuel tanks on the airplane. Fueling can be accomplished by the use of a single pressure fueling station through which all tanks can be filled partially or completely.

2. Q: What is the function of the distribution system?

The distribution system allows fuel to be supplied to the engines and APU. In addition, the system can be used for refueling the tanks and for fuel transfer between the tanks.

Text Analysis III


(Para. 2)There are 3 tanks for fuel storage and 2 vent surge tanks for temporary fuel storage. Tank No.1 is located in the left wing, tank No. 2 is located in the right wing and center tank is located in the fuselage under the passenger cabin. The 2 vent surge are located outboard of the main tanks. All fuel tanks are fuel tight. Close metal-to-metal fit of all parts forms the basic seal. Sealing compounds and sealedfasteners are used on all joints to complete the fluid tight seal. Two of the wing ribs contain a series of baffle check valves to prevent fuel flow away from the boost pumps.

3. Q: Do you know the function of each part of a fuel system?

(Para. 3)

The fueling system provides a means of filling the fuel tanks

on the airplane. Fueling can be accomplished by the use of a

single pressure fueling station through which all tanks can be

filled partially or completely. Alternately, the main tanks (No.1

and No. 2) can be filled through the over wing parts. The

center tank can be filled by transferring fuel from

the main tanks using the fuel station.

(Para. 4)

The components associated with the fueling system are the fueling

station located under the right wing leading edge outboard of the engine,

3 float switches — one for each tank, prevent the tank from being

overfilled. The tank fueling float switches are located near the top of each

tank and sense full tank quantity. The tanks can be filled to any desired

quantity, the float switches sense full tank condition and automatically

stop the fueling. Power requirements are supplied by ground power, APU

or the battery. Pressure fueling can also be done manually. Maximum fuel

pressure is 55psi (pound square inch).

(Para. 5)

The distribution system allows fuel to be supplied to

the engines and APU. In addition, the system can be

used for refueling the tanks and for fuel transfer

between the tanks. The distribution system utilizes

pumps, valves and truing for engine and APU feed.

The fueling station is used for refueling and transfer

operations which are only possible on the ground.

(Para. 7-8) The fuel quantity indicating units measure the weight of usable fuel in the tanks. Two types of quantity indicators are used, one is capacitance indication, another one is a manual measuring stick. Digital fuel quantity indicators show the weight of fueling each tank. Each indicator consists of a single chip microcomputer system and a digital liquid crystal display (LCD). The microcomputer measures the capacitance and resistive current in the tank units. It monitors the leakage current and when reaches an unacceptable level, and error code 0 through 10 illuminates to assist in troubleshooting the system.
