Question: The F-22's Intake can move up, down, i.e. F-15, but can the vertical move fore and aft or port & starboard?

I'm not sure I understood that. No, the intake doesn't move. The tails are conventional-moving, left-right 30 degrees (I think, it's been awhile since I read Jay Miller's book).

Variable Geometry Verticle Stabs? Never heard of that!

I have picture's of the intakes being moved like the F-15(Up&down) if you look at the vertical tails you can see they are not flush to the aircraft( There two piece units.) the outside of the vertical tail is shaped like a quater moon and does not , like I said, fit flush to the airframe. The inside is sraght like most aircrafts verticsl tail. look closely and you can see that the vertical tail is not setting flush to the F-22. Now there has to be a reason for this, my brother-inlaw who is a pilot, thiks it could be moved fore and aft at high AOA. I have no Idea how to send pictures to this site(I don't even own a camera) but check them out at Airlines.net Winger2

No - the intakes are fixed.

No - the vertical stabalisers are conventional.

Also please remember we have no idea what you're talking about. Can you please try and be more descriptive, or maybe give us the internet address to these pitures?

Do those covers, for a lack of a better term, inside the intakes play any role in air flow management when the F-22 is in the air? Even though the actual intake frame does not move.

I'd like to see those.

I've gotten alot of pics from that site and I have never seen what you say. Give me the link, I think you're confused...

Which covers? If you mean you can't see the engine face it's because that's the way it's supposed to be: the intakes are S shaped so that radars can't get throught to the engine face. Which would make the a/c unstealthy.

The covers clearly evident in the photo and in every other image or video which shows them deployed.

Do you mean the white wall inside the intake? That's actually the wall of the intake; as I said, the intakes are S shaped. That "cover" is the wall of the intake, directly beyond which lies the side weapon bays.

PhillyGuy,

Tinito is right. the f-22 intake has s-shaped intake tunnels which were deliberately designed to hide the engine face since the engine blades are high sources of radar return.

to the OP, the intakes are fixed. the vertical tails are also fixed and as flushed as they can be.

The YF-23 did however have verts that moved and this picture of the intake, http://community.webshots.com/photo/ful ... 4140NVSdwP of the one at Wright-Patt looks like it might have intake ramps. This site, http://www.fighter-planes.com/info/yf23.htm says it had an "auxiliary blow-in inlet door" Maybe the original poster saw something from the -23 and just thought it was the -22

EDIT:
I can't see the image because apparently only your "friends" can see it.

check photos on this site, pages 52 photo #311, 56 #343, 75 #261 and page 81 #73. Also site ARLINERS.NET
f-22 photos page 2, #13 and page3 #17. THE WHOLE INLET MOVES LIKE THE F-15, I'm not talking about inside the inlet, sorry I did not make myself clear. winger2

Shrug

That doesn't tell me much

If this is what you're referring to, it's not the inlet that's moving, it's the angle of the photo. The inlet appears to move but it's really just the angle of the shot.

It would be nice if you could post a pic with an arrow pointing precisely where it is, because maybe there is something moving, although I highly doubt it.
