I'm sorry is this self-made(fanmade) or did you get it from an official source?
What is the benefit of rectangular form of F-22 engine?
Why we don’t adopt this on our TFX?It's about the stealth of the rear side. Round nozzles reflect more radar echo. in the F-35, the stealth of the rear is not as good as the F22.
Why we don’t adopt this on our TFX?
Too expensive..
Also don't forget technological and engineering challenge of this type of design, it would require more time to develop this instead of adopting already available technology. It affects radar visibility but engine itself is more important in terms of visibility (Like F35 / which is still not reliable).. I really like and prefer ej200 and thrust vectoring over this.. May be there is still possibility to go with RR to develop similar one.How much more expensive that we can not adopt it on our TFX?
EJ200 in standard form develops 13500lbf dry and 20200lbf WAB thrust.Also don't forget technological and engineering challenge of this type of design, it would require more time to develop this instead of adopting already available technology.

EJ200 in standard form develops 13500lbf dry and 20200lbf WAB thrust.
If a TVC Is added, it will develop 16200lbf dry and 23100 WAB thrust. TVC version somehow used a lot less fuel and significantly increased the life of the engine.
Rolls Royce was offering us a standard EJ2XX version with an increased output of 17500lbf dry and 27000lbf WAB thrust. If TVC was added to this engine it would certainly be in the range we are looking for now, with all the added advantages that come together with a TVC engine.
I am still hopeful for a collaboration between RR and TFX.

The technology is round about 30+ years old. Of course a challenge, but not impossible. Dear lord! We want to make a 5. Generation Fighter Jet. We can have both, trust vectoring and rectangular nozzles.

Why is the F-22 the only stealth fighter to use rectangular exhaust nozzles if a rectangular nozzle is indeed most stealthy?
Answer (1 of 24): Cost. The rectangular shape is not actually the main reason they are stealthy, the rectangular shape was the result of design constraints in a 2D vectoring nozzle. The stealth comes from the materials and subtle curvature of the external surfaces of those nozzles. The F-22 was...www.quora.com
Does he mean 30000 lb thrust afterburning or dry? 30000 lb afterburning should be in the 20 or late 10s-ish thousand pound thrust range dry.“the Raptor’s F119 underrated public figures”
The stones finding their places now.
The F-22’s published figures are 2x35000=70000 lbs of thrust versus 84000 lbs MTOW
Temel Kotil talks about 2x30000=60000 lbs of thrust and 60000 lbs MTOW for TFX.
Now I’m thinking that F-22 engines are actually 42000 lbs of thrust for each, not 35000.
Most probably with AB values.Does he mean 30000 lb thrust afterburning or dry? 30000 lb afterburning should be in the 20 or late 10s-ish thousand pound thrust range dry.
Thrust with afterburner of F-22 could be 37-39 thousand lbs range according to Air international.
I don't think the T-FX will reach the F-22s thrust to weight values, the engines on the F-22 are some of the most advanced in the world unmatched by anyone as of now. I don't think Turkey will be able to achieve something similar but I'd like to be pleasantly surprised.Most probably with AF values.
To reach dry T/W value of F-22, F-110’s dry value should be increased about 2000 lbs for 60000 lbs MTOW.
For a 60000 lbs MTOW, you don’t need such a high tech. That’s the point.I don't think the T-FX will reach the F-22s thrust to weight values, the engines on the F-22 are some of the most advanced in the world unmatched by anyone as of now.

Well you don't need high tech engines but it sure helps a lot for a variety of reasons.For a 60000 lbs MTOW, you don’t need such a high tech. That’s the point.
