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

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,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。

The development of what it said would be 'the world's fastest hypersonic wind tunnel' was revealed by the state-run inhua 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”

Wind tunnels test how air will pass over a solid object, hel 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。
