The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, all-weather, supersonic stealth fighter aircraft.As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities.
Pilots will take off, accelerate to high speed at low altitude, and then pull the aircraft vertical or nearly vertical to quickly climb to the aircraft's cruising altitude. Some aircraft such as the Lockheed Martin F-22 Raptor can use thrust vectoring to assist in the rapid attitude change required for the maneuver. [2]
Lockheed Martin/Boeing F-22 Raptor at the 2008 Joint Services Open House ... The current AIM-120D version has a maximum high altitude range of greater than 160 km ...
The two Pratt & Whitney F119 that power the F-22 Raptor make it the most capable supercruise-capable fighter aircraft in service. The F-22 Raptor can supercruise above Mach 1.5 without external stores. [19] [20] [13] The EJ200 engine built by EuroJet Turbo GmbH mounted in the Eurofighter Typhoon.
Delivering almost 22% more thrust with 40% fewer parts than its F100 predecessor, the F119 allows the F-22 to achieve supercruise speeds of up to Mach 1.8. [ 1 ] [ 2 ] The F119's nozzles incorporate thrust vectoring that enable them to direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
F-22 Raptor, the first U.S. operational supermaneuverable fighter aircraft.It has thrust vectoring and a thrust-to-weight ratio of 1.26 at 50% fuel.. Traditional aircraft maneuvering is accomplished by altering the flow of air passing over the control surfaces of the aircraft—the ailerons, elevators, flaps, air brakes and rudder.
Flight testing for the F-22 continued until 2005, and on 15 December 2005 the USAF announced that the Raptor had reached its initial operational capability (IOC); with the collapse of the Soviet Union and the Department of Defense focused on counterinsurgency at that time, F-22 production only reached 195 aircraft and ended in 2011.
