How does F-22 Thrust Vectoring work?

[Hitperson]

one thing that confuses me is how the thrust vectoring works??

how efficient is it on the use of the engine power of the F22??

Um. if you want to bring the nose up, you point the engine exhaust up so the back end of the plane pushes down.

It works exactly how you think it would.

basically thurst vectoring means that the engine nozzle is able to turn. This means that the thrust the engine gives will not be directed just forward, but also up or down. So in other words, with thrust vectoring when you want to go up the engine nozzle turns upwards, pushing the back of the aircraft down, which in turn causes the nose of the aircraft to rise rapidly.
Here is a vid that shows you how the engine nozzle works.

And it's very effective, makes turning a lot faster.
Here is a vid, you can clearly see how the thrust vectoring affects the aircraft.

Wrong. It's magic.

Uhh I thought it would be obvious.

Of course it is obvious.

It's magic.

Basically you have circle directing high pressure hot gases out of the engine. Thrust vectoring means you can change the way the circle points, or change the shape of the circle, in order to help maneuvering. It has been used before the F-22, most notably on the Harrier (of course a slightly different concept with multiple outlets), as well as the SU 30 and many missiles.

Hello, as far as i know this system works on fuel flow pressure to action nozzle actuator, quite risky business to use skydroll (hydrolic pressure) in this hot part of plane. Also u have the afterburner system who brings fuel to this area, maybe a derivation or his own feed ?

I think the F-22 vectorial thrust only works on the pitch axis, the Sukhoi system works on the 3 axis, the Su-35 is the first opérationnal fighter with 3 axis vt, Indian Air Force buy some of them last year.

Have a look on this vid :Aviation Video: Soviet Skies | Patrick's Aviation
U see a close up on nozzle, dude it's living !!

but how efficient is it now??

i know for the harrier it uses up a ton of fuel and burns up engines pretty quickly.

Burning fuel is not because of thrust vectoring, it's from VTOL. Thrust vectoring on the F22 only goes like 50deg up or down to give it more pitch control. There is also a system on a Mig29 variant that can vector up down left and right, and this was also tested on the X31.

Engine life and fuel consumption have nothing to do with thrust vectoring.

If i'm right, its essentially to aid in maneuvering in addition to the control surfaces. Out of curiosity, does the F22 have any horizontal vectoring (Essentially turning w/o rudder)
