What is the performance of the F22 Raptor?

1 Brief introduction of technical performance of American F22 Raptor.

At present, only the United States has designed and manufactured two truly fourth-generation fighters, F22 and F35. European and Russian fighters can't meet all the requirements of the fourth generation fighters, or they are still in the stage of demonstration and testing. The American F22 fighter represents the highest technical level and is the fighter with the strongest operational efficiency at present. F22 fighter 1990 was first tested and put into service in 2005.

On April 26, 2005, the US Air Force announced some performances of the first batch of F/A-22EMD Raptor fighters.

Total length:18.9m.

Total height of the machine: 5.08m.

Span:13.56m.

Wing area: 78.03 square meters

Empty weight:16000kg (latest estimate)

Take-off: ≥ 35,000 kg

Internal combustion: 14375L (this is estimated according to the fuel consumption of F 1 19 engine combined with the range of F22).

Load: 2270 kg (fully loaded)

Loading capacity: ≥ 9000kg (including plug-ins, up to 12 tons).

The weight ratio of fuselage materials: titanium alloy 42%, composite material 23%, 15% aluminum alloy, and other 20%.

Upper limit: 18288m

Controllable angle of attack maneuver: more than plus or minus 60 degrees.

Actual supersonic cruise speed: 1.72 Mach (exceeding YF22 index 15%).

Maximum speed: Mach 2.0

Acceleration capacity: 54 seconds (exceeding YF22 index by 2%)

Sea level climb rate: 355m/s.

Maximum g limit: -3g/+9g (normal working limit of human body)

Instantaneous hovering angular velocity: 30 degrees/second

Acceleration ability: (from 200 knots to Mach 65438 +0) less than 30 seconds.

American F22 adopts more advanced, comprehensive and accurate design technology than American F 1 17A.

The frontal radar reflectivity of American F22 is 0.0065 m2 (the frontal radar reflectivity of Russian Soviet 27 is 10 m2).

The reflectivity of F22 radar is 2 ~ 3m2, which is only1100 of that of Su -27 radar.

F22 also adopts advanced infrared stealth technology. The rectangular nozzle is cooled by jet, and the vertical tail, horizontal tail and tail strut extend backward, which can shield the infrared radiation of the engine nozzle. The skin adopts Boeing's topcoat infrared suppression coating, which effectively reduces the infrared radiation generated during supersonic cruise. The F 1 19 engine also has infrared suppression measures, which can reduce the infrared radiation intensity by 80% when the thrust decreases by 2%-3%, narrow the infrared radiation lobe width, and effectively narrow the attack range of infrared guided missiles.

Better than F22, it adopts a new stealth design, changes the radar wave scattering center and infrared radiation center, and increases the miss distance of enemy radar guided missiles and infrared guided missiles. In addition, the F22 is equipped with new intelligent infrared decoy and advanced towed radar decoy.

Engineer Loma claims that the stealth performance of the F-22 will enable it to safely approach the S-300 class air defense forces, with a distance of about 24-25 kilometers, but if JDAM is used, its effective distance to attack the S-300 is almost the same (so the US military is actively developing the F/A-22 bomb bay to launch from 400-600 kilometers to 1000).

Australian Ministry of Defence's assessment:

Maximum detectable range of Russian-made 1 1 phased array radar (equipped with Su -35/ Su -37/ Su -47 radar) /R-77 air-to-air missile marker (agat8b-1103m/9b/KLOC

F 15/SU27 (former RCS: 5-10m2):180-200km/70-80km/15-20km.

F/A- 18C (former RCS:1-2m2):140-165km/45-55km/1015km.

RAFALEB/C(RCS:0.5m 2):90-95km/25-35km/8- 10km。

F/A- 18E/F (former RCS: 0.1m2): 75-85km/20-25km/7-8km.

F-22A (front RCS: lower RCS: 0.01m2):15-18km/5-6km/1-2km.

In addition to stealth and infrared radiation suppression, the American F22 fighter also adopted advanced electromagnetic wave RF management and suppression technology. The RF management technology of FA-22 makes it impossible for the enemy to intercept the radar beam of F22 to detect its existence, because it will be easier to be discovered by the enemy if advanced electromagnetic wave RF management and suppression technology are not adopted.

FA-22 adopts advanced APG-77 active phased array radar. In addition to traditional radar functions, American APG-77 radar also integrates intelligence detection, electronic jamming, communication and other functions, and supports passive positioning and detection capabilities. The scanning speed of APG-77 radar is extremely fast, which reduces the probability of being intercepted and identified by the enemy, and meets the low interception (LPI) requirements of the US military. The low interception technologies adopted by APG-77 include controlling the transmission power according to the needs of target detection, spreading spectrum with camouflage codes, etc.

APG-77 radar also has the ability of non-cooperative target identification (NCTR), which can identify and classify long-range targets without using the friend-or-foe identification question and answer device that is easy to be intercepted. The principle of NCTR is to rely on the extremely high resolution (up to 30cm) of the reverse synthetic aperture technology of APG-77 radar to analyze and process the echo of the rotating blades of the fighter engine flying in the distance, calculate the number and speed of the blades of the fighter engine in the distance, and identify the friend or foe.
