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.
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.
Conversely, a square flat plate of area 1 m 2 will have an RCS of σ = 4π A 2 / λ 2 (where A=area, λ=wavelength), or 139.62 m 2 at 1 GHz if the radar is perpendicular to the flat surface. [2] At off-normal incident angles , energy is reflected away from the receiver, reducing the RCS.
A US Air Force senior airman with the F-22 Raptor Demonstration Team prepares to signal to the pilot. ... and in $300 million worth of assets," referring to the high price tag of an F-22 aircraft.
Missile DATCOM is a widely used semi-empirical datasheet component build-up method for the prediction of missile aerodynamic coefficients. It is an example of an engineering aeroprediction method which can be used to generate an aerodynamic database of the vehicle’s aerodynamic coefficients at various flight conditions.
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.
The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range. Much of the technology developed for the APG-77 was used in the AN/APG-81 radar for the F-35 Lightning II , and in turn the technology from the APG-81 was applied to the upgraded ...
According to Lockheed Martin in 2004, the only fifth-generation jet fighter then in operational service was their own F-22 Raptor. [2] [40] Lockheed Martin uses "fifth-generation fighter" to describe the F-22 and F-35 fighters, with the definition including "advanced stealth", "extreme performance", "information fusion" and "advanced sustainment".
