BEIJING: China is building the world's fastest hypersonic wind tunnel to develop spaceplanes, official media has reported.
為了研發航天飛機,中國正在建造世界速度最快的風洞。
"The 265-metre-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 of the Chinese Academy of Sciences (CAS), told China Central Television over the weekend.
Han said the current wind tunnel could simulate flights ranging from Mach 5 to 9. Researchers from CAS in Beijing have successfully tested one hypersonic plane in a wind tunnel at such speeds, state-run Xinhua news agency reported.
他介紹道,目前的風洞能夠模擬的飛行速度介於5馬赫至9馬赫之間。
中科院高溫氣動力國家重點實驗室的研究人員,已經在風洞成功對一架超音速飛機進行該速度的試驗。
The new wind tunnel will help China take the lead in wind tunnel building, though competition from other countries is still fierce, Han said.

China may build anything but no use. India will simply buy and get the latest technology from anybody. Why waste time to build?

中國也許什麼都會造,有什麼用?
印度會買,能夠從其他國家買到最新技術。
為什麼浪費時間去研發?

What I find interesting is that the article makes NO mention of the military applications this technology will afford China whereas the Western media has zeroed right in. China is developing aircraft capable of reaching US shores with nuclear warheads in just 14 minutes, with the craft capable of hypersonic flight speeds of up to 27,000 miles per hour (43,200 kmh) - 35 times the speed of sound. They will be tested in China''s military-grade wind tunnel, set to be the world''s fastest hypersonic facility when construction is complete ''by 2020. Currently, the world''s most powerful wind tunnel is the US LENX-X facility in Buffalo, New York, which operates at speeds of 22,000 miles per hour (36,000 km/h).The Chinese hypersonic vehicles that will be tested in this wind tunnel could be used to deliver missiles, including nuclear weapons, to distant targets around the world within minutes of launch.

India has to consider her common citizen''s freedom .
印度不得不考慮本國老百姓的自由啊

While China progresses with technology, India is playing petty politics. Dont know if democracy was the right thing for india having seen the state of affairs.

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.
為了研發新一代超高速飛機,中國宣布正在建造世界速度最快的風洞。
然而,這種風洞也可以用來試驗超音速導彈技術。
目前世界上最先進的JF-12風洞
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.
這一進展是新華社周一晚些時候披露的,新華社稱該風洞是“世界最快的超音速風洞”
超音速重型轟炸機
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.
風洞,是以人工的方式產生並且控制氣流,用來模擬飛行器或實體周圍氣體的流動情況,以幫助設計師改進啟動外形,減少物體高速時的應力點。
'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.
中科院高溫氣動力國家重點實驗室的研究員韓桂來介紹,這個風洞模擬馬赫數可以達到25
To compare, the current fastest generation of fighter jets can travel up to speeds of around 2.5 Mach.
作為對比,目前最新戰機的速度大約是2.5馬赫。

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.

我們攔截不了他們的導彈,他們也攔截不了我們的。

"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 "........
“總統先生,我們捕獲中國發射導彈的信號。我們覺得應該是核襲擊”
難道你們不確定嗎?
不完全確定,可能是電腦故障了。
考慮到他們導彈的速度,你們有30秒的時間做決定是否發動報復
好吧,那就發射吧

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