F22 capabilities

I read this article on a web site today.

A significant milestone in advancing the capabilities of high-performance aircraft was achieved recently at the Dryden Flight Research Center, Edwards, CA, when a highly-modified F-15 aircraft employed thrust-vectoring of its engine exhausts at speeds of almost Mach 2.

I realize this news is a couple of years old but I wasn't familiar that you could thrust vector at Mach 2. I believe this would have been testing for the F-22. Think about the dog fighting capabilities of being able to substain supersonic speeds and thrust vector in dog fights.

Does anyone know if the Su-37a is capable of performing such feats?

Thanks for the input Seekerof.

No problem...give it some time..others will give their imput.

are you talking about the Berkut or about the Flanker?

S-37 Berkut Achievements
The S-37 was built to validate and gain experience with various advances in technology that could be incoorperated in a future Sukhoi fighter.



this is the spec Berkut and Flanker.

I also read somewhere that Russia will have 150 Berkuts in service by 2007.
Sorry I forgot where I read this info.

from what i heard... dog fights take place in subsonic speed

yeah they do take place in subsonic speeds. But there are exceptions.

it would be to much g's if you were in a dogfight at super sonic speed. if there would be to much g's your brain would suficat from no blood. g's are gravitys. like some combat planes can pull up to 7 g's (gravities) in corners and acceration.
if i am wrong please correct me.

9g:s is the limit for most aircraft and pilots..

How ever Mirage 2000 can stand 12g:s.. (but pilots cant..)

And what comes to the dog fight at Supersonic speeds..

It isnt practical as turn circles would be in 'many kilometers class'..



Air to Air combat usually takes place at 500-1100km/h speeds.. sometimes even as slow as 250-300km/h and most common speed being about 750km/h i belive..

thanks for your help
if you are a untrained pilot like me you will die at 7g's

Well,

Without G-suit one will 'pass out' in 6,5-7g (usually)..

G-SUIT

A G-Suit is a pressurized suit. G-Suits are standard equipment which fighter pilots wear. In a real aircraft when the pilot pulls g-forces, the G-Suit (actually only pants which cover the legs and stomach section) inflates and squeezes the pilot to prevent all his/her blood from rushing to their lower areas. This helps keep the pilot from passing out due to the effects of g-forces . In the simulator the suit inflates to make the pilot aware of what g's he/she would be pulling even though no gravity pull is experienced.

Russian,

DO NOT COPY AND PASTE ENTIRE ARTICLES FROM OTHER WEBSITES!!!

I already gave you a warn for posting copy-paste posts, and trashed 6 threads you started.

This is your final warning!

One of the most improtant capabilities of the F-22 is supermanuverability. To the best of my knowlage, it was the first fighter that was spacificly design to manever at high G-force without loseing supersonis speed. Imagin pulling 7,8 or maybe even 9 G's (I'm not sure)at mach 2. If this is true it's an awesome capibility and makes the F-22 a force to be reckoned with. Can anyone verify the G-limit for a mach 2 "supermanuver" in the F-22?
