F-22 video

considering i have a small part in the structural integrity of this aircraft, my interest is warranted. But even if i didn't have anything to do with this guy, this video is damned cool for those of us that love "airplane noise".
here is the email i received today, with a link to a video put out by the air force (it's on an air force website). i don't know if you can appreciate just how amazing this aircraft is, but holy shyte, i would not want to have to go up against this critter in a dogfight, considering what it can do.


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 the all 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.

Some used to think the 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.

The video is about 5 minutes long but the last 30-40 seconds are priceless.

Airshow Langley


ACC recently approved the Raptors new DEMO profile. This was the first show. Five minute video.

Watch the elevators of the airplane in this demo. They work independently.
It also has vectored thrust.

ACC = Air Combat Command (for the non-Air Force folks)


*Supercruise: The F/A-22 can sustain ! superso nic flight without the use of fuel-gulping afterburners.

I thought the darn thing was gonna start flying backwards a couple of times. A truly amazing aircraft.

Bo,

I've had a little bit to do with this aircraft, too. We're getting 3 squadrons up here at Elmendorf and I wrote the Electrical section of the RFP for their hangar facilities.

I don't think this bird will ever have to do any dogfighting because they'll detect an opponent and shoot it down prior to their being detected.

A truly amazing aircraft.
