Before a new type of airplane goes into service,every part of it
is tested again and again.But there are two tests that are more
important than all the others.
The first is called the" tank test".A modern airplane must fly
very high in the sky.Air must be pumped into the plane so that the
passengers can breathe.The metal structure(结构) of the plane has
to be very strong for this reason.When the plane is filled with air,
the air presses against the skin of the plane inside.The pressure (压
力) on a small window is like a huge foot that is trying to get out.If
a small part of the plane were to fail,the plane would explode in the
sky.To test the structure of the plane,the plane is lowered into a
huge tank or container of water.Then it is filled with air.The pressure
inside the plane is greater than it ever will be when it is high
up in the air.Finally,there is an explosion.This does not cause so
much damage inside the water tank as it would anywhere else.
Engineers can discover which part of the plane has broken.Then that
part is made stronger.
The most dangerous test happens when the new plane is going
through test flights in the air.The test pilot must find out exactly
what happens when the engines(发动机) are all shut off at once.
The plane begins to fall like a stone.It is the pilot's job to find out
how he can get control of the plane again.These two tests are
examples of how planes are made safe before they ever carry passengers.

我很慢,等等我.
在一种新型的飞机进入服务之前,它的每一个部分会进行一次又一次的测试.但是有两个测试是比其他测试都重要的.
第一个被称为“坦克测试”.一个现代飞机必须飞非常高的天空.空气必须注入飞机,这样
乘客就可以呼吸.因此,金属结构的飞机是很强的.当飞机充满了空气,飞机的空气按进飞机的表面里.压力在一个小窗口就像一个巨大的试图离开的脚,如果飞机的一小部分发生故障,飞机就会在天空中爆炸.为了测试飞机的结构,降低到一个巨大的水舱或容器的平面.然后,它充满空气的压力,比在空气中,飞机比以往高时承受的压力更大.
最后,他就会爆炸.这不会引起水箱内的破坏与其他地方.工程师可以发现飞机的哪个部分坏了.那一部分是由更强.最危险的测试是新飞机测试的时候,通过测试飞行在空中.试飞员必须找出确切的原因,当引擎都关闭.飞机开始下降就像一块石头.找出它是飞行员的工作,他如何能控制飞机.这两个测试就是飞机在承载乘客之前如何被安全制造的例子.
