 Russian media: Chinas j-20 is difficult to produce high performance in the near future.


China fighter -20 fourth generation fighter [global military May 6th] the Russian satellite news agency, 4 in May, reported the progress made in the study of stealth materials for fighter planes in China, which could further enhance the radar stealth of the fourth generation fighters. According to satellite news agency, Chinese scientists reported that Chinese scientists have made progress in making new generation of aviation metamaterials in recent times. 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 future, it will help China Aviation greatly improve the structure of the 4++ generation fighter that is being re produced. Vasily Cashin, a Russian military expert, commented on the satellite news agency. This man-made metamaterial does not depend on its intrinsic chemical elements, but on the structure of man-made materials. The properties obtained by metal materials include the ability to greatly improve the absorption of radio waves, sound and light, as well as to protect the refraction of controlled radio waves and light waves. The material used in the military is only a small part of the applicable 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. As we all know, metamaterials were used in the body of the latest fighter -20 that was installed in China last year. The Russian Soviet -57 fighter aircraft also used this material in its design. At present, Su -57 is still conducting extensive tests, and this year conducted the first combat test flight in Syria. But these two models are difficult to produce in the most recent time. 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 simpler and improved four generation machines. The development of metamaterial absorbing coatings for the four generation machine is one of the possible ways to solve the problem in the long run. But it cant be very fast. The existing technology for manufacturing supermaterials is extremely complex. Usually, 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. China is not the only country to study the reduction of existing aircraft reflector metamaterials. The US Air Force and other services have invested heavily in reducing aircraft, missiles, UAVs and ground radar reflectors and reflectors. In addition to studying aviation metamaterials, Russia also studies the use of this material in the field of communications and computers. Among them, in 2013, the joint research team of Russia and Germany made quantum metamaterials for the first time in the world. This material can be used in future electronic products.
