From the F-22 Demo Parameters:

Target -
Altitude 1,000'AGL
KCAS 80
Power Setting Cruise to Mil
AoA 36

Limits -
Altitude 900'AGL
KCAS 75
Power setting MIL
AoA 40

Description notes: performed into the wind.


Thing looks like it's on a rail in that shot. Rock solid.

Going by the number of air show accidents of other nations. I would say that the specs for the f-22 is flying well within its envelope.

Although technically, not at an air show, this is too good not to post. Make sure to turn your volume up to hear the thunderous, crackling roar of that F-135 engine. Wish I could wake up to the sound of this every morning... :P

One word: POWER!

Does anyone have data on its rate of climb? It looks to be a clean F-15 on the way up, if not faster. If I'm not mistaken, it even pulled off a vertical climb in military power (not sure of its weight/internal fuel). That was damn impressive.

Pierre Sprey, where are you? LOL...

Well I don't have the specific rate of climb figure but mathematically, subsonic acceleration has a strong correlation with rate of climb, and given F-35 out-accelerates a clean Su-27 by 20%, so... :mrgreen:

Please stop this line. There is NO data to use to compare these two in similar conditions.

Yeah I got taken to task on that one too.

But if there's no data, there's no data and it shouldn't be repeated. I just wish we had SOME data, as to the F-35's rate of climb. It sure looks sprightly, but youtube vids can only show you so much. I'll note though a non-afterburning climb (especially still being within the parameters of the airfield), is quite telling.

Practice of the new demo routine. Most interesting move is around the 6 min mark.

The angular rotation / nose pointing is quite good beginning at 5:47.

The more I see this jet, the more it grows on me.

I swear it has Viper DNA in the fabric of its being, and a Velociraptor in its soul.

Velocity Vector Roll @ 8:25 ?

Really puts the spurs to her @ 8:42...

Roll rate beginning at 8:47 ?

ITR @ 9:18 !

So much raw power, yet so precise, so fluid. The word that keeps coming to mind when I see the F-35 fly is effortless.

The F-35 is the idiot savant of tactical air combat.

Stepping through the video @ 8:54... can really see the stabs differentially deployed, along with ailerons, to affect the roll rate. Dojo seems to be completing a 360° in about 2 seconds flat, including roll begin and roll end. So his max roll rate is somewhere north of 180°/sec.

I can't tell what the heading change is of the turn @ 9:18. At first I was guestimating 90° in around 3 seconds, but that is a swag. Not counting the roll-in, which takes about 15 frames or ~0.5sec, then the bat turn takes about 138 frames, or 4.6 sec. But I can't tell the heading change. If 90° in 4.6 sec, then that is about 19.5°/sec. So... seems like that turn is somewhere between 19.5°/sec and 30°/sec.
