Paint common sense: why is the body of stealth fighter painted in black?

Core tip: in the early morning of January 17, 1991, people in Baghdad, the capital of Iraq, were still in a sweet sleep After taking off from the base, several planes with strange shapes and dark colors quietly entered Iraq's airspace, and suddenly appeared over Baghdad They dropped precision guided laser guided bombs on the communication building in the center of the city, which lasted for 45 minutes After that, the air raid alarm sounded in Baghdad The mysterious aircraft that successfully completed the air raid mission was the famous stealth aircraft F-117 F-117, which was invaded by the United States as early as December 1989 Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: In the early morning of January 17, 1991, people in Baghdad, the capital of Iraq, were still in sweet dreams After taking off from the base, several planes with strange shapes and dark colors quietly entered Iraq's airspace and suddenly appeared over Baghdad They dropped precision guided laser guided bombs on the communication building in the center of the city Forty five minutes later, Baghdad The air raid warning just sounded The mysterious aircraft that successfully completed the air raid mission was the famous stealth aircraft f-117.f-117 of the U.S air force, which had been used in the American invasion of Panama in December 1989 It was not until the Gulf War that the military value of the stealth aircraft was fully reflected: during the war, 95% of the heavily fortified targets in Baghdad were bombed by F-117 at night During the war, F-117 bombed at night There was no loss of an F-117 during the mission All this is due to the F-117's stealth (or stealth) technology Why are F-117 stealth fighters mostly black? In principle, the stealth of the stealth aircraft is not invisible to our naked eyes Its purpose is to make the radar unable to detect the existence of the aircraft At present, stealth aircraft can reduce or eliminate the usefulness received by radar as much as possible Because light color hardly absorbs radar wave, dark color is easy to absorb radar wave, and black material is not easy to reflect light, it is easy to find that the stealth fighters at present are mainly dark color Stealth technology makes you unable to detect the first application of modern stealth technology in the aircraft, stealth aircraft is the fastest-growing and most mature The outstanding representative is several stealth aircraft developed by the United States successively F-117 mainly adopts shape invisibility Its shape is very strange It adopts the multi-faceted and polygonal design of diamond cutting technology The whole fuselage is composed of straight lines, which can scatter the radar waves to all directions The radar cross section of the B-2 stealth bomber is only 0.1 square meters, which is the result of the use of "flying wing" shape and a large number of carbon fiber composite materials and special absorbing coating From F-117 to F-22, American stealth technology has gone through a track of "shape + paint + material" Comanche stealth helicopter developed by the United States is the first real stealth helicopter in the world Its radar cross section is only 1% of that of other helicopters and 1 / 400 of that of Apache At present, stealth coating has been widely used in the appearance of aircraft, warships, tanks and other equipment, and has become an effective means of anti radar detection and prevention of electromagnetic wave leakage or interference Among them, the plasma stealth coating emits strong rays during the flight of the aircraft, and the high-energy particles make the air outside the aircraft surface ionize to form a plasma layer, which has a good absorption effect on microwave and infrared radiation There are two main phenomena when the electromagnetic wave radiated by the enemy detection radar hits the plasma cloud surrounding the aircraft: firstly, part of the electromagnetic wave energy is absorbed by the plasma cloud Because the electromagnetic wave interacts with the charged particles of the plasma when passing through the plasma cloud, its energy is greatly reduced; secondly, the plasma cloud can make the electromagnetic wave diffract, and the electromagnetic wave bypasses the plasma cloud without reflection, which will greatly reduce the reflected electromagnetic wave signal, making it difficult for the radar to find the aircraft hidden in the plasma cloud Infrared stealth coating is a kind of nano organic coating Nano ultrafine powder can not only absorb radar wave, but also visible light and infrared ray It can avoid radar reconnaissance, and also has infrared stealth effect It can be seen that the stealth of fighter is not based on the color camouflage of the surface The stealth coating and advanced stealth technology play an important role in this The home of coatings focuses on coating, diatom mud, paint coating, coating process, news information and coating of fireproof coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fireproof coating,
