China Claims It Can Make Stealth Fighters Even More Stealth

中国声称可以让隐形战机更加隐形

Key Point: Chinese scientists claim they have developed a new kind of material for making aircraft less detectable by radar.

要点:中国科学家声称他们已经研发出一种新的材料,可使飞机更难被雷达探测到。

But the development probably is not the breakthrough that some observers claim it is.

Prof. Luo Xiangang and colleagues at the Institute of Optics and Electronics, part of the Chinese Academy of Sciences in Chengdu, said they had created the first-ever mathematical model to precisely describe the behavior of electromagnetic waves when they “strike a piece of metal engraved with microscopic patterns,” according to South China Morning Post.

The newspaper cited a statement Luo’s team posted on the academy’s website on July 15, 2019.

“With their new model and breakthroughs in materials fabrication, they developed a membrane, known as a ‘metasurface,’ which can absorb radar waves in the widest spectrum yet reported,” South China Morning Post reported.

但这一新进展可能并不像某些观察人士所称的那样是个重大突破。

根据《南华早报》的报道,中国科学院成都光学和电子研究所的罗先刚教授和他的同事们称他们已经创建了第一个数学模型来精确描述电磁波“照射到一块刻有细微图案的金属”时的活动。

该报引用了罗的团队于2019年7月15日在中科院网站上发表的一份声明。

据《南华早报》报道,“他们通过新模型和材料制造上的突破,研发了一种薄膜,称为‘超表面’,可以吸收迄今为止已知的最广谱的雷达波。”

Luo’s claims and breathless comment on their implications do not constitute a major change in the way companies develop stealth warplanes or the military balance of power among operators of such aircraft.

That’s because the metasurface Luo is working on is just one example of type of metamaterial that has been the subject of research all over the world. It’s not terribly new. If and when it begins to appear in front-line aircraft, it could improve stealth qualities in a wide range of aircraft on both sides of the Pacific Ocean.

Metamaterials have been a popular research subject for more than a decade, Financial Times reported in 2018. “Metamaterials first captured the public imagination in 2006, when John Pendry of Imperial College published two papers showing how to create a Harry Potter-style invisibility cloak using the specially engineered materials.”

罗的说法和评论,并不能构成隐形战机研发方式或拥有此类飞机的军事力量之间平衡的重大变化。

这是因为罗研究的超表面只是世界各国正在研究的超材料类型中的一种。这并非什么新鲜事。如果它开始出现在前线飞机上,则可以提高太平洋两岸大量飞机的隐身性能。

据英国《金融时报》2018年报道,超材料成为热门研究课题已超过十年时间了。“超材料第一次引起公众的注意是在2006年,当时帝国理工学院的约翰·彭德里发表了两篇论文,展示了如何使用这种特殊工程材料制作出哈利·波特风格的隐形斗篷。”

Lockheed Martin, which makes the U.S. military’s F-22 and F-35 stealth fighters, is a big investor in metamaterials. In 2017 the company partnered with a Canadian firm that produces lightweight metamaterials for solar-energy applications.

Metamaterials clearly are promising and, over time, could wind their way into various countries’ warplane-production. But they are not revolutionary.

South China Morning Post in a 2018 story gave voice to the skeptics. “There is debate in the research community about the value” of metamaterials under development by a research team at Southeast University in Nanjing, the newspaper explained.

“There is not a clear-cut definition of a metamaterial, so not everyone in the research community agrees with their claim,” a researcher with the Chinese Academy of Sciences said. “The consensus is that their product still has a lot of room for improvement.”

洛克希德·马丁公司是美国军方F-22和F-35隐形战斗机的制造商,也是超材料的重大投资者。2017年,该公司与一家加拿大公司合作,生产用于太阳能领域的轻质超材料。

超材料显然是很有前途的,随着时间的推移,它们可能会逐渐进入各国的军用飞机生产领域。但它们并非革命性的颠覆。

《南华早报》在2018年的一篇报道中表达了怀疑。该报解释说,南京东南大学某研究小组正在研发的超材料的“价值在研究界存在争议”。

中国科学院的一名研究人员说:“对于超材料并没有明确的定义,所以并不是所有研究领域的人都同意他们的说法。大家一致认为,他们的研究结果仍有很大的改进空间。”

I have a million stealth fighters in the air flying all over the World right now. You can't see them, or detect them. Doesn't mean they aren't there.

我现在有一百万架隐形战机在世界各地飞行。你看不到它们,也探测不到它们。并不意味着他们不存在。

 

R

China also claims to see through stealth tech yet they are trying their hardest to convince others it does work.

中国也声称能识破隐形技术,他们正在尽最大努力说服别人这是可行的。

 

tim

They absolutely can develop a more stealth plane, AS soon as they can get steal the technology from someone who discovers and manufactures the design.

他们绝对可以开发出更多隐形飞机,只要他们能从发现并制造这种设计的人那里窃取技术。

 

Tony

I think the real story here is China is behind in research on meta materials. Now they have to do their research from scratch and just starting to realize how far they are behind. One way to find out how far they are behind is to publish a scientific paper and see the reaction.

我认为真正的问题是中国在超材料的研究上落后了。现在他们必须从零开始研究,并逐步意识到他们究竟落后了多少。要想知道他们落后了多少,一种方法是发表一篇科学论文,看看反应。

 

Boricua

An advice to Chinese Air force, it you want stealth for your fighters don't paint them bright yellow!

给你们空军一个建议,如果你想隐形,就不要把你们的战斗机涂成亮黄色!

That’s like Steve Martin’s old routine, “How to Become a Millionaire: ‘First, get a million dollars”. For China, it’s “First, steal BETTER stealth technology”.

这就像史蒂夫•马丁的老套路:“如何成为百万富翁:首先,你得有100万美元。”

对中国来说,应该改成“首先,你得窃取更先进的隐形技术”。

 

Russell

"China Claims It Can Make Stealth Fighters Even More Stealth" MmmHmm....And we've developed Hyperbolic Inter-Dimensional Mega-Thrusters and PU238 Explosive Space Modulators. Just ask Marvin.

“中国声称可以让隐形战机更加隐形。”嗯,我们还开发了双曲型超空间推进器和PU238爆炸空间调制器。问问马文就知道了。

 

rick

Stolen technology , reverse engineering , patent stealing , China is great at what they do

窃取技术,逆向工程,中国很精于此道。

 

Nickyesterday

A mathematical model. That is still a long way from working reality. Hyperbole by the article.

这只是一个数学模型。离实际运用还有很长一段路要走。这篇文章有些夸张了。

 

Conch

Yep. If you fly them into the ground like a dart they will be extremely stealthy.

是的。如果你把它们像飞镖一样扔到地上,它们会非常隐蔽。

 

Joseph

It won't matter because it will still be Made in China, and we all know what that means: cheap and destined to break in record time!

这并不重要,它仍将在中国制造,我们都知道这意味着什么:便宜,而且注定马上出故障。

 

Gabriel

Most people here are being condescending even though 98% of products in their homes are made in China.

这里大多数人都一副高高在上很了不起的样子,不过他们家里98%的产品是中国制造的。

Shouldnt this say: China claims it can make the stolen technology of stealth fighters even more stealth just by saying they can,

难道这不应该说么:中国能把偷来的隐形战机技术变得更加隐形。

 

FRED

Did they steal our latest radar absorbing material?? Just saying we had had it already for years. But hey painting the aircraft YELLOW will sure help!

他们偷了我们最新的雷达吸收材料吗??我们老早就发明出来了。但是把飞机漆成黄色肯定是会有助益的!

 

sawall2 days ago

superpowers say this often, that x is better than whats out there... very often in China's case its simply reverse engineered military tech, or intermediary tech, that is simply not utilized by other superpowers - thats domestically produced.

超级大国经常说,X比别人好……在很多情况下,中国只是简单地对军事技术,或者中间技术进行反向工程,而其他超级大国根本没有利用这些技术——这些技术都是国内生产的。

 

George

We won't know what works until we engage in battle.. So China and Russia; keep claiming you have an edge over the US with your technologies. All will be hashed out in battle.

除非我们在实战中使用,否则我们不知道实际效果如何。中国和俄罗斯;继续吹嘘你们在技术上比美国有优势吧。战场上见真晓。

 

Brian

Aircraft Radar cannot detect any of these aircraft after they crash......

雷达无法探测到坠毁后的飞机

 

F4L

China's newest jets aren't even stealth by 5th generation aircraft standards. So yeah, of course they can make them "more stealth."

按照第五代飞机的标准,中国最新的战机都算不上隐形战机。是的,当然他们可以使他们“更隐形。”

 

Galen Johnsonyesterday

It'll make a great exhibit until they steal the technology for an engine to power it and the technology for the advanced radar, sensors, communications and the weapon systems to take to battle. Without that, it's just another airplane.

只要他们窃取到了发动机,先进的雷达,传感器,通信等方面的技术以及武器系统,就可以搞个很棒的展览了。如果没有那些东西,这就是完全另外的一种飞机了。

 

John Woo

Its funny how every piece of new technology in China looks just like US developed equipment. To be honest, I feel sad for them......

有趣的是,中国的每一项新技术看起来都像美国研发的设备。老实说,我为他们感到难过。

 

Joseyesterday

Nothing new. Other materials have been used from rubber coatings in WWII submarines to special plating using amorphous alloys, all have some pros and cons. About 20 years ago worked on some of these and they were very good radar wave absorbents and or deflectors however cost, application and durability were always an issue.

不是什么新东西。从用于二战潜艇的橡胶涂料到使用了非晶合金的特殊镀层,都各有一些优点和缺点。大约20年前,人们研发了一些材料,是很好的雷达波吸收剂或导向板,但是成本、应用和耐久性一直是一个问题。

 

Ryesterday

Really China?? Well in that case, I have a stealth jet fighter park outside on my driveway! Oh..whats wrong, you cant see it?????? Well trust me its there!

真的吗,中国? ?好吧,那样的话,我也可以说我有一架隐形战斗机停在外面的车道上!哦,怎么,你看不见??相信我,它就在那儿!

 

Adrianyesterday

NOTE:... ALL ''Stealth Fighters'', can be seen from space by the Hundreds of satellites place there for 'that' specific reason.

注意:……所有的“隐形战机”,都会被太空中的数百颗卫星发现。

 

Sai

But why claim such a thing? I would keep it a secret if it was true. If it was false, I would bluff like this. UNLESS...

为什么要说出来呢?如果这是真的,我绝对会保守秘密。如果是假的,我就会像这样虚张声势。除非…

 

CharlesRyesterday

Of course they can. they will just wait until America researches and designs the system and then copy it or steal it out right.

当然可以。他们会等到美国研究并设计出这个系统后,进行复制或者盗窃。

 

BenJ2 days ago

Bold claim from a country that stole stealth technology, my guess is they weren't able to reach that result on their own.

我猜他们凭自己的实力是做不到的。

 

Steve

By time China figures out stealth we will be using Quantum radars that can determine not only an aircraft, but exactly the size and shape

等到中国搞出隐形技术,我们就使用量子雷达了,不仅可以发现飞机,还可以精确地确定飞机的大小和形状。
