BEIJING: China has moved a step closer to creating a supersonic submarine that could travel from Shanghai to San Francisco covering nearly 9,900km in less than two hours, a Chinese scientist has said.

New technology being developed by a team of scientists at Harbin Institute of Technology’s Complex Flow and Heat Transfer Lab could make it easier for a submarine or torpedo, to travel at extremely high speeds underwater, the Hong Kong based South China Morning Post reported on Sunday.

一位中国科学家表示,中国朝开发超音速潜艇前进了一步,从上海到旧金山接近9900公里用时不到两小时。

据《南华早报》24日报道,哈尔滨工业大学复杂流动与传热实验室的一组科学家研发出了一项新技术,可以使潜艇或鱼雷更容易在水下以极高的速度前进。

The distance from Shanghai in eastern China to San Francisco in western US is about 9,873km. Li Fengchen, professor of fluid machinery and engineering, said the team’s innovative approach meant they could now create the complicated air “bubble” required for rapid underwater travel.

从中国东部上海到美国西部旧金山的距离大约是9873公里。哈工大流体机械及工程研究所教授李凤臣说,这组科学家的技术创新意味着,他们现在能制造出水下高速航行所必需的复杂“超空泡”。

“We are very excited by its potential,” he said. During the Cold War, the Soviet military developed a technology called supercavitation, which involves enveloping a submerged vessel inside an air bubble to avoid problems caused by water drag. The supercavitation, torpedo called Shakval was able to reach a speed of 370km or more — much faster than any other conventional torpedoes. Li said the team of Chinese scientists had found an innovative means to address problems like designing a submerged vessel to travel at high speeds to generate and maintain the air bubble with a rudder placed within it to avoid direct contact with water.

“我们对它的潜力感到非常激动,”他说道。

在冷战期间,苏联军方研发出了“超空泡”技术,该技术理论上可以把一艘潜艇包裹在一个气泡里,以避免水阻力引起的问题。采用“超空化”技术的鱼雷可以达到370公里以上的时速,比常规鱼雷的速度快得多。

李凤臣指出,这组科学家已经找到了一个创新方法,解决诸如潜艇高速航行时产生并维持气泡的问题,避免直接与水接触。

Its application so far limited to unmanned vessels, such as torpedoes, but nearly all of these torpedoes were fired in a straight line because they had limited ability to turn. Once in the water, the team’s supercavitation vessel would constantly “shower” a special liquid membrane on its own surface.

迄今为止,该技术仅限于无人潜艇,以及不需要改变方向的鱼雷。一旦入水,这些科学家的“超空泡”潜艇将不断在其表面制造一层特殊的液体薄膜。

Although this membrane would be worn off by water, in the meantime it could significantly reduce the water drag on the vessel at low speed, Li said. After its speed had reached 75kmph or more the vessel would enter the supercavitation state. The man-made liquid membrane on the vessel surface could help with steering because, with precise control, different levels of friction could be created. “Our method is different from any other approach, such as vector propulsio,” Li said.

“By combining liquid-membrane technology with supercavitation, we can reduce the launch challenges and make cruising control easier,” he said. However, Li said many problems still needed to be solved before supersonic submarine travel became feasible.

虽然这层薄膜将被水磨损,但在同时,它可以极大地减少潜艇在低速行进时受到的水阻力。

等时速上升到75公里或以上时,潜艇将进入“超空泡”状态。上述人造的液体薄膜将有助于驾驶,通过产生不同程度的摩擦,可以获得精确控制。

李凤臣说:“我们的方法与矢量推进等其他任何方法都不一样。通过把液体薄膜技术与‘超空泡’技术结合起来,我们可以极大地降低风险并使航行控制更为简单。”

然而,李凤臣表示在超音速潜艇变得可行之前,还有许多问题有待解决。

What is the highest underwater speed of any submarine or torpedo at present? Seem unrealistic currently to make supersonic submarine

目前,潜艇和鱼雷的水下速度最高是多少?似乎目前造超音速潜艇是不现实的。

Indian IIT and IIM students cannot even build a silencer for the loud autorickshaw noise that the whole country suffers. Thus us the state of indian education… Look at Chinese universities who are developing supersonic submarines and will have a prototype in a year or less… Who cares, indian it guys hknow how to pass Agarwal classes and they think they are theoretical genius. You should see every IIT and IIM guy walk on the street. They think they are some sort of genius.. Frog in well mentality… It’s such a shame that these universities are fooling the whole country

印度理工学院和印度管理学院连机动三轮车的消音器都造不出来,这就是印度教育的现状。反观中国大学,他们可是在研发超音速潜艇,且一年甚或不到一年就能造出一个样品。

谁在乎呢,印度理工学院和印度管理学院的那帮家伙懂得如何通过考试,自以为是理论天才。看看走在街上的那两所大学的学生,趾高气扬的,以为自己是天才,井底之蛙心态。

太丢脸了,这些大学在糊弄整个国家。

Seems to be dream of traveling 9,900km in less than two hours by a sub. Let us wait and watch how they achieve it.

一艘潜艇不到两小时跑完9900公里似乎是梦想。让我们拭目以待他们如何实现。

Whatever speed they actually attain, I think these submarines will create a huge swathe of destruction in the marine environment as they race around, because of their powerful shock waves. Also, I wonder what chemicals they will be using as their so-called “liquid membrane”. No doubt it will be highly toxic to marine life. But what do the Chinese care about environmnent? They are conditioned from birth to respect nothing but money and power at any cost.

不管速度多少,我觉得潜艇高速航行时会产生强大的冲击波,给海洋环境造成巨大的破坏。此外,所谓的“液体薄膜”采用什么化学物质。毫无疑问,对海洋生物肯定是剧毒的。中国人会在乎环境污染吗?他们天生就目空一切,一切向金钱和权利看齐,且为此不惜代价。

Stop talking about it, this is a new faked up by a Sounth Korean news agency, But this new tech is used in the one of the China newest missile

大家别讨论了,这是韩国新闻机构捏造的新闻。不过这个新技术已经被用于中国最新的导弹上。

If China already had that kind of technology it wouldn’t be relying on the rest of the world and its slave labor to make money from selling cheap D1ld0s.

如果中国真的已经有了这种技术,那么就不用依赖其他国家了,也不用靠他们的奴工来赚钱了。

@Daniel that’s untrue that we Indians are lagging. .. it’s a democracy and things gets delayed.. our gov will do all that is good for the country and man kind unlike china who are of destructive nature. doesn’t mean that china has taken over india in all aspects. china growth is not sustainable and gov policies are not people friendly.. though we are developing slower than these chinese basterds but we have solod base.wait and watch.. I am positive.

我们印度人落后了,印度是民主国家,办事难免有所拖延。

我们的政府全心全意为人民服务,哪像中国,夹杂着破坏的性质。

中国并非各方面领先印度。中国的发展是不可持续的,政策对人民不友好。

虽然我们比这些中国混蛋发展得更为缓慢,但是我们更扎实。等着瞧,我可是很乐观滴

Very hard to actually implement this. Long and perhaps not feasible to develop such a submarine.

实际上,这个很难实现,研发这种潜艇也许是不可行的

I’m a bit suspicious here whether this can be really achieved or not. Supersonic means more than 12k km per hour. If Chinese scientist can do this then this will be a miraculous invention and will definitely help man kind.

我对是否能实现超音速潜艇有些怀疑。超音速意味着每小时12000公里。如果中国科学家能够实现,那么必将是一个神奇的发明,对人类肯定有帮助。
