DEMONSTRATION FLIGHT OF THE F/A-22 RAPTOR
Fact Sheet Because of security they still couldn't demonstrate all of it's capabilities
Fast ("super-cruise*) and stealthy, and integrated avionics are cool, but what's really impressive is the F/A-22s low speed stability and maneuverability.
In the late 40s and to early 60s aeronautical engineers were
going nuts on how to shape intakes to handle both
subsonic and super-sonic air flows, without stagnation or compressor
stalls. Supersonic in itself was a big challenge because you had to use
shock waves to slow the intake air mass to sub-sonic before it hit the
compressor blades, or they would stall. The engineers figured it
out, but the solution was keeping a lot of air going in the front end to
make sure all the hot air kept going out the back end. As you watch this Mach 2 airplane suspend
motionless in air and do tail slides, be aware of the truly amazing
performance of the engines and intakes engineering.
Some used to think the Russian Su-27 / Su-31 Cobra maneuver was the epitome of
3rd- to 4th-generation fighter maneuverability. That snap maneuver doesn't hold a candle to what this
two-dimensional vectored-thrust fighter with fat independent horizontal stabs
can do at low speed. There must be far
more tricks up its sleeve in the high subsonic dogfight speed range.
This video is about 5 minutes long but the last 30-40 seconds are priceless.

ACC recently approved the Raptors new DEMO profile.
This was the first show.
Watch the elevators of the airplane in this demo. They work independently.
It also has vectored thrust.

*Supercruise" The F/A-22 can
sustain supersonic flight without the use of fuel-gulping afterburners
