The F22 Raptor is the most modern technika mp3 fighter aircraft of the U.S. Air Force. The story of the F-22 began in 1976, when the U.S. Air Force prfte whether they knnte apply the stealth technology in the next Luftberlegenheitsjger. technika mp3 Initial studies began in 1969 and were as Advanced Tactical Fighter (German: "advanced tactical hunters"), technika mp3 respectively. 1975, the Air Force created a rough plan, which provided for the prototype testing in between 1977 and in 1981. However, doubts arose as to the stealth technology, the first large research project delayed opening of this technique until 1976, when the Lockheed Have Blue program began, from the the F-117 Nighthawk emerged. 1981 urged the Air Force to the aircraft manufacturers to submit their suggestions. The planned combat aircraft should ungefhrdet can ground and air targets of air defense missiles bekmpfen in the Soviet hinterland. This goal required a mandatory supercruise and stealth characteristics. About it, a highly integrated avionics was required to relieve the pilot and thus increase its efficiency in combat. As early as 1983, the Air Force beschftigte with the development of the engines. This thus began three years before the design of the airframe, since the Air Force had already had negative experiences at P & W F100 engine for the F-15 in this area. The companies General Electric and Pratt & Whitney received in October of the same year an order of over 200 million U.S. dollars to design a matching engine. Pratt & Whitney developed the XF119 based on the PW5000, while the General Electric GE37 XF120 further developed, which was equipped with a variable Nebenstromverhltnis (English "Variable Cycle Engine"). In October 1985, the Air Force called on manufacturers to December for deals leave a fighter plane, the mid-1990s could ablsen both the F-15 Eagle and the F-16 Fighting Falcon. However, the Air Force decided in July 1986 to a grundstzlichen plan alteration. The decision technika mp3 about the winner of the competition should no longer be based on soil tests, but on the basis of flight demonstrations, which should take place end of 1991. Half a year later, in April 1987, we issued a development order for two industrial consortia, which were gefhrt by Lockheed and Northrop. The volume amounted to 691 million U.S. dollars, the job was limited to 50 months. The first FlgE the prototypes should be held in October 1989. To the construction technika mp3 cooperated with General Dynamics Lockheed and Boeing, Northrop worked technika mp3 with McDonnell Douglas. The prototypes technika mp3 were designated YF-22 "Raptor" (Lockheed) and YF-23 "Black Widow II" (Northrop), each team had to build two identical machines. The F22 was known as playing Ace Combat or HAWX Tom Clancy's also among the gamers is this jet not too short. The armament Since the F-22, unlike most new aircraft models, not designed as a multi-role combat aircraft, technika mp3 they only verfgt over a limited number of compatible weapons. technika mp3 The air-to-air armament technika mp3 consists of the AIM-9 Sidewinder and AIM-120 AMRAAM, for the combating of ground targets technika mp3 are przisionsgelenkte type bombs GBU-32 JDAM, and GBU-39 SDB to Verfgung . [16] Air-to-ground missiles, cluster bombs or Marschflugkrper can not be mitgefhrt, which significantly einschrnkt the possibilities of the F-22 as fighter-bombers. However, the flight characteristics of the machine offer significant advantages for the use of weapons, as their large Flughhe technika mp3 (up to 19,811 m) combined with their consistently high cruising speed (Mach 1.5) both fired missiles and the bombs dropped zustzliche kinetic energy gives. The arms themselves are preferably located in the four internal Waffenschchten the F-22 to the stealth characteristics of the machine is not impaired. However, hereby offer other advantages over the gebruchlichen external weapon stations. So mounting the weapons does not degrade the aerodynamics of the machine so that it can maintain its maneuverability, speed and range. This is the case of conventional machines such as for example in the F-15 or Su-27 is not the case, since external
