航空工程英语段落翻译

1.A spoiler is a device intended to reduce lift in an aircraft. Spoilers are plates on the top

surface of a wing which can be extended upward into the airflow and spoil it. Flaps are hinged

surfaces on the trailing edge of the wings. As flaps are extended, the stalling speed of the

aircraft is reduced, which means that the aircraft can fly safely at lower speeds (during takeoff

and landing). Slats are on the leading edge of the wings which, when deployed, allow the wing

to operate at a higher angle of attack. They are intended to reduce the stalling speed by

altering the airflow over the wing.

1.扰流板是用来降低飞机升力的装置。扰流板是机翼上表面的板，它可以向上延伸到气流中，从而

扰乱气流。襟翼是机翼后缘铰接的表面，随着襟翼的伸展，飞机的失速速度降低，这意味着飞机（在起

飞和降落期间）可以以较低的速度安全飞行。翼板位于机翼的前缘，当展开时，可以使机翼以更高的攻

角运行。它们的目的是通过改变机翼上的气流来降低失速速度。

largest aircraft to be built, is the Antonov An-225. This aircraft comes from the

Ukraine, and it was built back in the 1980s. This aircraft includes 6 engines, mounted on the

wing. Its wingspan is 88 meters (289 feet) and it is 84 meters long (276 feet). This aircraft holds

the world payload record, after it transported 428,834 pounds worth of goods. Weighing in at

1.4 million pounds, it is also the heaviest aircraft to be built.

2.将要建造的最大的飞机是安东诺夫An-225。这架飞机来自乌克兰，建造于20世纪80年代。这

架飞机有6个引擎，安装在机翼上。它的翼展为88米（289英尺），长84米（276英尺）。这架飞机

在运送了价值428，834英镑的货物后，保持着世界有效载荷记录。这架飞机重达140万磅，也是将

要建造的最重的飞机。

737-300 is the same basic design as the 737-200, with a body stretch of 104 inches,

航空工程英语段落翻译

a wing tip extension of 14 inches, a horizontal tail extension of 36 inches, a larger dorsal fin

and strengthened stabilizer. The 737-400, relative to the 737-300, has body stretch of 120

inches, two additional overwing exit, tail skid, and strengthened landing gear.

3.737-300和737-200的基本设计相同；机身伸展104英寸，翼尖伸出14英寸，水平尾翼伸出

36英寸，有较大的背鳍和加强过的稳定器。77-400，相对于737-300，机身拉伸120英寸，并伴有

两个额外的位于机翼的出口，尾翘和加强起落架。

pneumatic system controls the temperature and pressure of engine bleed air source.

The pneumatic system provides high temperature, high pressure air for the air conditioning,

pressurization, wing and cowl thermal anti-icing. Also, the pneumatic system provides

pressure for the potable water system, hydraulic system and engine starters. The engine bleed

air systems are located on the engine and within the support strut.

4.气源系统控制着发动机排气气源的温度和压力。气动系统为空调、增压系统、机翼、发动机整流

罩防冻等提供高温、高压空气。此外，气动系统还为饮用水系统、液压系统和发动机起动机提供压力。

发动机排气空气系统位于发动机和支撑杆内。

air cycle machine is an integral unit of each cooling pack. The air cycle machine

consists of a turbine wheel and a compressor wheel mounted on a common shaft. Air flowing

through the air cycle machine drives the turbine, the turbine drives the compressor section.

As the air leaves the turbine it expands greatly. The expansion can cause the temperature of

the air to drop to sub-zero levels.

5.空气循环机是每个冷却机组的整体单元。空气循环机由安装在共同轴上的涡轮轮和压缩机轮组成。
