style="FONT-SIZE: 12pt"><BR> Fast (super-cruise*) and stealthy, and
integrated avionics are cool, but <BR> what's really impressive is the
F/A-22s low speed stability and <BR> maneuverability. In the late 40s and
to early 60s aeronautical engineers <BR> were going nuts on how to shape
intakes to handle both subsonic and <BR> super-sonic air flows, without
stagnation or compressor stalls. Supersonic <BR> in itself was a big
challenge because you had to use shock waves to slow the
<BR> <BR> intake air mass to sub-sonic before it hit the compressor
blades, or they <BR> would stall. The engineers figured it out, but the
solution was keeping a <BR> lot of air going in the front end to make sure
the all hot air kept go! nag <BR> out the back end. As you watch this
Mach 2 airplane suspend motionless in <BR> air and do tail slides, be aware
of the truly amazing performance of the <BR> engines and intakes.
<BR> <BR> Some used to think the Su-27 / Su-31 "Cobra" maneuver was
the epitome of 3rd <BR> <BR> to 4th generation fighter
maneuverability. That snap maneuver doesn't hold a
<BR> <BR> candle to what this two-dimensional vectored-thrust fighter
with fat <BR> independent horizontal stabs can do at low speed. There must
be far more <BR> tricks up its sleeve in the high subsonic dogfight speed
range. <BR> <BR> The video is about 5 minutes long but the last 30-40
seconds are priceless. <BR> <BR> ACC recently approved the
Raptors new DEMO profile. This was the first show.
<BR> <BR> Five minute video. <BR> Watch the elevators of the
airplane in this demo. They work independently. <BR> It also has
vectored thrust. <BR> <BR> ACC = Air Combat Command (for the non-Air
Force folks) <BR> <BR> *Supercruise: The F/A-22 can sustain supersonic
flight without the use of <BR> fuel-gulping
afterburners.<o:p></o:p></SPAN></FONT></P>
