中国宣布正在建造世界速度最快的风洞，英国网民评

China has announced it is building the world's fastest wind tunnel to develop a new generation of super-fast airplanes - but it could also be used for hypersonic missile technology.

为了研发新一代超高速飞机，中国宣布正在建造世界速度最快的风洞。

然而，这种风洞也可以用来试验超音速导弹技术。

目前世界上最先进的JF-12风洞

The development of what it said would be 'the world's fastest hypersonic wind tunnel' was revealed by the state-run Xinhua news agency late on Monday.

这一进展是新华社周一晚些时候披露的，新华社称该风洞是“世界最快的超音速风洞”

超音速重型轰炸机

Wind tunnels test how air will pass over a solid object, helping designers improve aerodynamics or reduce stress points for objects as they reach high speeds.

风洞，是以人工的方式产生并且控制气流，用来模拟飞行器或实体周围气体的流动情况，以帮助设计师改进启动外形，减少物体高速时的应力点。

'The 265-meter-long tunnel can be used to test hypersonic aircraft that can travel at speeds of up to Mach 25 (30,625 kph), 25 times the speed of sound,' Han Guilai, a researcher with China's State Key Laboratory of High Temperature Gas Dynamics at the Chinese Academy of Sciences, said.

中科院高温气动力国家重点实验室的研究员韩桂来介绍，这个风洞模拟马赫数可以达到25

To compare, the current fastest generation of fighter jets can travel up to speeds of around 2.5 Mach.

作为对比，目前最新战机的速度大约是2.5马赫。

This was a warning to Trump if he thinks he can carve out a piece of Syria and keep it.

We can't stop the missiles they've already had for decades, and they can't stop ours either. This is all just for show and much ado about nothing.

我们拦截不了他们的导弹，他们也拦截不了我们的。

无非是秀肌肉，虚张声势，别无其他。

"Mr President, we have picked up some missile launches in China. We think it could be a nuclear strike" "You mean you arent sure" "Not entirely. It could be a computer malfunction, but given the speeds their missiles can reach you have 30 seconds to decide on a retaliation" "OK, then launch "........

“总统先生，我们捕获中国发射导弹的信号。我们觉得应该是核袭击”

难道你们不确定吗？

不完全确定，可能是电脑故障了。

考虑到他们导弹的速度，你们有30秒的时间做决定是否发动报复

好吧，那就发射吧

They don't want America to drop any dem*acy on them so they are defending themselves.

他们不希望美国将敏煮强加给他们，所以想办法自卫。
