F-22 IN FLIGHT

OVERVIEW● The F/A-22 is the United States most deadly operational fighter.

● The "F/A" designates the Raptor as a "fighter" and an "attack" aircraft

● Capable of holding 13 tons(26,000 lbs.) of jet fuel!

● Weighs nearly 20 tons, not including fuel(as mentioned above) or bombs! (That is roughly the weight of 9 cars.)

● 62 feet long and has a wingspan of 44.5 feet

● Can travel 2 times the speed of sound

● Gets 0.4 MPG

INNOVATIONS IN F/A-22

The F/A-22 is the first American fighter aircraft with the ability to supercruise(fly at supersonic speeds)

● Can reach Mach 1.8- over 1.5 times the speed of sound

● Engines- can fly faster for longer periods of time, reaching far-off targets faster than other jets, and can carry more bombs in place of extra fuel.

● Jet engine- the nozzle is the first vectoring nozzle. That means the pilot can move, or vector, the nozzle up and down by 20 degrees.

● Stealth capabilities

● Can shoot down enemy before enemy knows it is there

● Information- the cockpit is designed to show information in a simplistic yet informative way, and has been described as like playing a video game.

STEALTH CAPABILITY: RADAR● Radar works by sending radio waves out from an antenna and

collecting the waves that bounce back from any objects 

● An airplane appears as a blip on a radar screen- larger aircrafts have larger blips.

● If the radio waves are deflected or absorbed so they don't return to the radar antenna, then the airplane is effectively invisible.

● It is so stealthy that it appears to be the size of a bumblebee when detected by radar, even though it is more than 62 feet long and has a wingspan of 44.5 feet.

● Curved surfaces and other design tricks to deflect radar waves in unexpected patterns

● Thick paint that can absorb radar waves instead of reflect them

STEALTH CAPABILITIES: OTHER

● Tracking the heat from jet engines is another common way to identify airplanes

● Blocking infrared emissions can fool a heat seeking missile

● Horizontal fins at the rear of the aircraft make the plane more maneuverable and act as a shield for the engine exhaust heat.

● F/A-22 can carry missiles inside the fuselage

● The F-15 and F-16 can only carry missiles under the wings, where they can reflect radar waves and make the plane much more visible.

DEFENSE

● Radar warning receiver 

● Missile-launch detector

● Countermeasures to heat/radar seeking missiles: flares to confuse heat seekers, small pieces of reflective material to disperse radar waves and confuse a radar-guided missile's tracking system

● Also, the radar can jam enemy electronics systems and communicate voice and data information over a secure link.
