Ford is showing off a new all-electric Mach E SUV.

福特正在展示一款新的全电动马赫E SUV。

In 1947, there was no wind tunnel data beyond Mach 0.85.

1947年那时还没有风洞实验数据，只有0.85马赫这个数据。

You can't learn to fly at Mach 20 unless you fly.

你飞不了20马赫，除非你继续飞。

And in the second flight, three minutes of fully-controlled, aerodynamic flight at Mach 20.

第二次飞行是历时3分钟的全程操控，空气动力飞行的速度是20马赫。

They want this, what's called the mach stem, to have a wide area of destruction.

他们希望这种被称为马赫茎的东西能造成大面积的破坏。

That happened in December 1953, after a few flights approaching Mach 2, twice the speed of sound.

这发生在1953年12月，几次飞行接近2马赫，是音速的两倍。

The objective is to develop fuel for ramjets, a type of engine that operates efficiently only above Mach 3.

目的是为冲压式喷气发动机(效率仅高于3马赫)开发燃料。

" Your mach—" Peter was completely lost. " I don't know what you're talking about. I don't—what machine? "

“您的机——”彼得彻底糊涂了，“我不知道您在说什么。我不——什么机器？”

At Mach 20, we can fly from New York to Long Beach in 11 minutes and 20 seconds.

在20马赫的速度下，我们可以在11分钟20秒内。从纽约飞到长滩。

Still, mach I or the speed of sound is not something that`s reached by passenger planes, at least not anymore.

仍然，马赫一号或声速不是客机所达到的，至少不再如此。
