Since the first exposure of the J-20 to now, its body coating has changed several times frequently, this change is not "casual" for it! Today's low visibility camouflage coating is China's latest stealth coating technology, to surpass the United States F22, F35, J-20 tail spray stealth defects have been perfectly resolved. The stealth coating of the J20 is mainly the refraction, absorption, weakening the reflected signal and achieving stealth purpose, which is the symbol of the five generations of machine.
while the J-20 was still in the technical verification phase, its coating was almost as good as
. The black coating should be similar to the U.S. F-117 paint, and then the FC-31 technology verification machine is also black stealth coating, we can call it the first generation of stealth paint. Because at that time, the J-20 has not yet been in service, but a verification model, the focus at that time is to assess the original performance of the J-20, if this stage on the addition of a variety of assistive technologies, will greatly affect the collection of data.
Over time, we found that the later J-20 suddenly changed to silver coating, which also means that the J-20 has become a project prototype, the choice of the main invisible coating will become the focus of this period. Immediately after, the J-20 has been exposed to the split version of camouflage painting and irregular camouflage painting, so that military fans are very happy. But at the same time can not help but wonder: Zhuhai Air Show debut at the same time there are two versions of coating fragmentation and irregular camouflage, which is the final final version?
to explain here, two different versions of camouflage have their own advantages! In terms of split camouflage, it is even better in visual concealment: irregular geometry with clear corners helps to interfere with the enemy's first judgment of our models and targets, and even interferes well with airborne infrared and distributed optical detection systems. On the other side, irregular camouflage coating is more conducive to weakening the optical characteristics of the aircraft's aircraft body, reducing the probability of detection by the enemy. There is no doubt that in the field of stealth fighter aircraft the United States is still the benchmark, reference to the U.S. military F-22 fighter aircraft, the use of irregular low visual camouflage coating, can be seen the superiority of this type of coating.
compared with the above several stealth machine, the fusion of Sumei style of domestic models obviously also have their own style, not only so according to domestic experts said that we use stealth materials are also the best. The same is the stealth fighter, the United States F22 moving into the air-conditioning room, sealed aircraft depot for skin maintenance, the United States stealth paint often after the flight off the paint, and our J20 or casually in the tin shed machine, do not need special treatment.
U.S. F22 and F35 stealth paint use conditions are very harsh, in addition to the mission to take off generally stay in the hangover, and the hanger is specially made, constant temperature and humidity. Domestic J-20 is the most simple, ordinary simple machine library on the line. Before CCTV interview pilots, behind the J-20 is in the simple machine library maintenance. It can be seen that China's stealth coating technology has been ahead of the United States, aircraft tail nozzle this biggest invisible defect has been perfectly resolved.
