The discovery of Technology Demon
‘Demon’ was developed by a Russian scientist, in 1966 by Dr. Pyotr Ufimtsev through a working paper titled method of edge waves in the physical theory diffraction (Tepian Wave Method in the Physical Theory of Diffraction) which is a working paper which is long enough but not long-winded, published by one of the media in Moscow in 1966. But this paper does not get a warm welcome by the experts there, because a lot of content that can not be digested by common sense. And Ufimtsev is an experienced expert in the Moscow Radio Engineering Institute.
Ufimtsev pure idea of radar and pelumpuhan formulation works tissue taken from the conclusion of raw British expert James Clerk Maxwell in the 19th century, after which mixed several times coupled with integrated reasoning, Ufimtsev calculates new ways, which form the specific geometric shape reflect electromagnetic radiation. By creating a radar cross calculations that can be easily overpowered. He set the formula-sided two-dimensional configuration, a procedure to tamper with the components in a radar. Result, the radar could be disrupted when confused with this two-dimensional rays. The beam is still not enough but if it is carefully calculated from it can create three-dimensional planes that are difficult to track by radar.
Theoretically, a lot of power to paralyze stealth, but very much needed computer network that works very quickly. Exactly like watching the ball by using binoculars where to localized but do not expect to menjejaknya that played like a ball, the players had the ball somewhere and could not shoot the ball that flew off somewhere with a pellet gun at him.
In 1979, Russia developed a reconnaissance aircraft and the pilot had managed to outwit anti-aircraft radars United States in the Nevada desert.
 Falling into the hands of the United States
In 1976, a copy of it eventually leaked and fell into the hands of the United States, and then translated by the division of the U.S. Air Force technology. Regularly, the experts at the Air Force describing, analyzing and developing technology that steath. Among a spy plane SR-71 Blackbird, F-117 and B-2.
 Principles of Stealth Aircraft
In principle, so that the plane will be a stealth (invisible) dalah way minimize the Radar Cross Section (RCS) which appeared on radar. Step taken is to make the design of the plane such that the surfaces of the aircraft as small as possible to reflect the energy emitted by the radar to be captured again by the radar antenna. Even if necessary form of the plane did not reflect radar energy. If reflected, tried to be the reflection of radar energy is directed in another direction so that if anyone was caught again, at least only a small portion. For that, the plane made a strange shape not as usual. As an example, the form of the B-2 aircraft that have the same range in length with a range of DC-10 aircraft but the shape is made flat and curved in the middle of the body. In such form, in addition to rapid propagation of the radar beam also slowed the reflection effect in all directions.
Wing shapes also affect the reflection of radar energy emitted. Form of the old wing straight into the side for example providing a perfect reflection so that the aircraft is easily detected. on the screen, point the aircraft RCS looked great.
Seeing this reality, then people make sayung wing backs, it does not minimize the reflection but more satisfying because the RCS is large, the delta was made to make the most of the radar beam on the wing, most of the cast into a different direction. Then made wings with crescent shapes like those of the planes the next generation. By creating an arc on the wing, leading edge, then the reflection in the other direction even more perfect.
Another design is to form a plane square-like shape in terms kubustik eye facets, as in the eyes of a dragonfly. Forms are also found in the helicopter on the generation-1980-1990’s as the AH-1 Cobra and AH-64 Apache so that the reflection of radar did not return to the radar antenna.
Then stealth aircraft design generally does not permit the Pylon or missile or rocket hangers suspended from the body and wings of aircraft such as the commonly found on aircraft. So that the missile was placed on the shelf-bombs (bomb bay) special.
Another way of using a special material known as RAM (Radar Anti-material) that be an energy-absorbing material radar beam. The materials include epoxy composites graphyte form of carbon. Because of that material, it is not reflected radar energy.
Nevertheless, the draft is still not perfect to fool radar. For example aircraft F-117 stealth successfully shot down by anti-aircraft missile SAM (Surface to Air Missiles) SA-2 Guideline of Serbia when the NATO air operation in Kosovo in 1999 during conflict.
