Wow Peter....At 1min 26 sec that looked like a "cobra" maneuver followed by an almost flat spin.....incredible...thank you for sharing.... :o

A very polished and professional display ;-)

I dunno though. I got a feeling when watching that vid.. who or what is the Raptor's projected nemesis :think: I appreciate one has to 'stay ahead' of the competition but it's more difficult than ever to envisage who the competition actually is. Anyone else feel like that or is it just me getting old :think:

Tony,

With independently operated fat horizontal slabs and vectored thrust, this machine can do some very impressive things...Including a complete 360 degree turn in less than 20 seconds. It can also maintain a M1.6 cruise without the use of afterburners :o

Reading the latest Aircraft illustrated Dave the F22 and the F15A through D are in a lot of trouble......Structural failure in the older F15C's and already in the first block of F22's...they have corrosion in the wing spars.....As to the nemesis.....They could be fighting us in the near future and maybe the Typhoon would go against it.....Ok maybe I Am getting old...... :roll:

Peter do you have any links or info released on the F22 stats...?

I would be interested to see the performance she is capable of...?

Not really Tony...Apart from what I already said...here is a small blurb in American:-

The F/A-22 is now operational, with several wings already flying in the Air Force. The JSF-35 'Lightening' is fast approaching operational, and can do much more than the F/A-22 - including literally stopping in mid-air from near super-sonic flight. The Su-27 / Su-31 'Cobra' maneuver was essentially a 'one-trick pony' maneuver. The F/A-22, and especially the JSF-35, can stop and eat a Sukoyhan doing the 'Cobra' maneuver, plus do so much more.

And, as pointed out by some ex-F-4 Phantom drivers, ANY of these maneuvers in an F-4 Phantom would have resulted in stall/fall/spin. H. Ownby (USAFA '69)

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 mas! s 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.


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.


Note also, that the RAPTOR does a complete 360 degree turn in less than 20 seconds !


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.


*Supercruise: The F/A-22 can sustain supersonic flight without the use of fuel-gulping afterburners. I.e. 1.6 m+

I enjoyed watching one of the Gents at Nellis do a complete airshow routine including a vertical climb to Fl230 and back - not within the confines of the
airbase but within the confines of the length of the runways and the width of the pararells - the most impressive display being as Peter said slowing to less than 120 knots pitching up (dirty) applying power and climbing away
