How are the secret aircraft made by the secret?

Stealth Leantplanes are aircraft with special design functions that make them less detectable visually, thermally, audible and on the radar. They are by no means invisible, but are much less identifiable than a conventional aircraft. Stealth Aircraft are part of a continuous plant between Stealth and Detection Technology in the war. The first two secret aircraft flew from 1977 to 1979. The aircraft design approach was unique in concentrating around the engineering goal to reflect the radar wave perpendicular to the aerodynamic aircraft. Reflection of radar waves is necessary to prevent the radar waves from jumping to detect the enemy on the ground. Classification aircraft are not designed for speed or maneuverability, but rather for secrecy. Both early prototypes crashed because of their poor stability.

Although he usually painted black, this is not the optimal color for the aircraft to be secret. Contraintuitively, at an altitude that most of the secret aircraft fly,would be the white bottom to be the least visible. Black color is to make the aircraft look more intimidating. There are anti-deficiency detection technologies, but their efficiency is uncertain, they require computing performance and detectors are not mobile.

Because they are intended to avoid detection, the secret aircraft would be helpless in the duel. Their primary purpose is to spy or start an attack on enemy defense in the first stage and soften them for conventional unfortunate forces.

The first secrecy of Airplane was F117 Nighthawk , a descendant of Lockheed's has a blue project. Other secret aircraft include F-22 Raptor and B-2 Spirit Bomber , the most expensive aircraft ever built for $ 2.2 billion. It was built for Cold War operations, capable of carrying nuclear and conventional payloads and would probably be the primary bomber for nuclear attacks if it broke out inÁlka between the US and the USSR.
