Chinese Researchers Develop Material to Make Jets Stealthier than Ever
The new material is roughly ten times thinner than previous radar-absorbing substances, making it viable in fighter jet and ship construction.
By Jay Bennett
Nov 12, 2015
In a paper published in the Journal of Applied Physics yesterday, Chinese scientists from Huazhong University of Science and Technology detail the development of a new material that could be used to construct fighter jets capable of thwarting even the most advanced radar technology.
Other materials that can absorb microwave radar signals in ultrahigh frequencies (UHF) are too thick to use in fighter jet construction. But lead researcher of the paper, Wenhua Xu, says the new material is almost ten times thinner than anything else available. The material could be used in a variety of military aircraft and ships, but it is particularly interesting for its potential application in fighter jets.
The most advanced microwave radars broadcast signals at UHF that bounce off objects like aircraft. The returning microwave signals are detected by antenna arrays, allowing radar technicians to detect objects even if they are obscured by clouds. Anti-radar materials absorb some of those signals, making a large object appear smaller than it is. But current stealth technologies employed in aircraft like the F-35 fighter jet are not particularly effective against UHF signals. The newly developed material might be.
Huazhong University's material is composed of various layers and can be "tuned" to absorb a wide range of microwave frequencies. A metal slab sits on top of a layer of thin metal honeycomb, and under that is an "active frequency selective surface material" made of a .04 mm layer of copper resistors and capacitors. Underneath all that is a circuit board with semi-conducting diodes and more capacitors.
The components and structure of the new material are openly published in detail, suggesting that China is not attempting to covertly develop a new stealth fighter jet. However, if the material is as effective as advertised, it does indicate a significant advance in China's stealth technology, considered one of the most important aspects of modern warfare.

Much curious and desperate for this aircraft more than F22 Raptor. Finally the J31 V2 under testing. The latest picture of this predator. Pakistan Airforce has been waiting for this for a long time. Purely for PAF front line. PAF abandon J10A&B recruitment process even when China was ready to provide us on a soft-loans. Pakistan gearing up JF17 From V1 - V3 and heavily rely on F16 until this machine will officially available. This aircraft will independent Pakistan Airforce from the American one and only frontline military hardware F16 with ZERO string attached like JF17.

Is this a recent test flight or an old image? Does anyone know if the FC-31's prospects on being a carrier-based aircraft have changed or not?

Once PAF chief said that PAF and CAC has good understanding we have worked together on JF17 ...and it's very possible that we may work with them in the future

Is there any news about CAC single engine stealth Jet?

The question is what evidence of a CAC single engine stealth jet? If there is none ... then we have to assume that such a project does not exist or is negligible.

Latest rumors: the so-called V3 model is actually a new FC-31 version that is going to compete with J-20 as the next generation aircraft carrier borne fighter (歼-31舰载型方案细节曝光 未来或与歼-20展开竞争)

Here are many more images of the same model ...

Thanks ... but I have a bit of a feeling that this is more a model-company - just look at the old H-5 in the background (second image) - and as such more a what-if than a real replica of a true project.
