 Russian media: China Aviation metamaterials or stealth capability of the four generation fighters


Reference News Network reported on May 6th, Russian media said that Chinese media recently reported that Chinese scientists have made progress in the manufacture of new generation of aviation metamaterials. According to the Russian satellite news website May 4th, these materials can greatly reduce the radar reflector of the fourth generation fighter. Perhaps the work in this direction is still in its early stage, but in the long run, it will help China greatly improve the structure of the improved fourth generation fighter. Russian military expert Vasily Cashin commented on this. Cashin thinks that the properties of this kind of artificial metamaterials are not the intrinsic chemical elements, but the artificial material structures. The properties of these materials include greatly improving the ability to absorb radio waves, sound and light, while also ensuring the refraction of controllable radio waves and light waves. Reported that the use of this material in the military is only a small part of its application field. It can also be used in solar energy, radio technology, computers, medicine and many other fields. Reducing the radar reflector of fighter planes is only one of them. Photo: the Chinese Air Force fighter -20 will be trained in actual combat. Xinhua News Community (Li Shaopeng) According to reports, it is well known that metamaterials were used in the body of the latest fighter -20 fighters installed in China in 2017. The Russian Soviet -57 fighter aircraft also used this material in the design. At present, Su -57 is still conducting extensive tests, and this year conducted the first combat test flight in Syria. However, it is difficult for these two models to achieve mass production in the short term. The reason is that its production is rather complex and expensive. For solving many tasks, their high performance is also redundant. Therefore, in the next few decades, the five generation will be used in conjunction with other improved four generation machines. The report says that the development of metamaterial absorbing coatings for the four generation of aircraft is one of the possible ways to solve the problem, but it can not be very fast. The existing technology for manufacturing supermaterials is extremely complex. It is usually done only in the laboratory. Therefore, it is impossible to carry out large-scale reconstruction of the existing hundreds of aircraft. Perhaps in the next ten years, production technology will go to a new height and prices will drop. At that time, the existing research results can be put into production. Reported that China is not the only country to study the reduction of existing aircraft reflector metamaterials. The US Air Force and other services are investing heavily in reducing the ground radar reflector and light reflecting surface of aircraft, missiles and UAVs. In addition to studying aviation metamaterials, Russia also studies the use of this material in the field of communications and computers.
