J-20 front view

Nah! not scary, I'd fly it! but those verts are definitely "long throw", I've never seen another set of verts at quite those angles?? LOL

It's in "park" status. The all moving vertical stabilizer turns 90 degrees at this status (maybe as air brake?)

STR is related to thrust and enhanced by thrust vectoring, ITR is the max lift the aircraft generates.

thus, F-22 indeed has very likely better STR unless you prove J-20 has better engines than F-22.

ITR is much less clear, it is hard to tell, here no one can really say much without the take off weights and the average wing loading and thrust to weight ratio.

J-20 could have higher ITR, but lower STR.

unless you prove J-20 can supercruise, J-20 is in big disadvantage

STR is related to drag, not just thrust. We don't know the drag or lift profile for either the J-20 or the F-22. I'm not interested in a J-20 vs F-22 cockfight though. I'm curious to know what made Forbin so sure in his determination.

Either way we know that the J-20 in its current form is superior to existing 4th generation fighters in both the super and subsonic regimes.

Just the hydraulics turned off and all the moving surfaces surrendering to gravity's pull.

not necessarily, if you mean the fighters china has made up to now, probably it is true, versus their new Su-35 i would like to read an unbiased report, neither pro-Russian nor pro-Chinese, but if the J-20 surpasses the J-10 i think it is more due to stealth, than aerodynamics

like i said before, without proper engines Forbin is very likely right in STR and cruising speed, but in my opinion its engines are not match for what the top other Russian and American fighters have, but who knows i might be wrong, but i guess he has a little bit more credibility than you if you can not prove China has engines as good as those in F-35, F-22 or PAKFA

Su-35 is a 4++ fighter though.

And you know this because...?

I think because nearly 10 years a go this video caused a stir -

He claims the F-22 having an STR of 28 deg/s at 20,000 ft F-22. Rafale was "RUMORED" to hit close to 28 deg/s at 25,000 ft. Off-course there are many unknown variables.

I think this is where the whole F-22 has the best STR came from.

It's not just about engine power. A jet fighter's max STR is ultimately limited by its aerodynamic design, and not by its max engine power. High alpha capability is an important determinant of STR and we know that the J-20's aerodynamic design is built towards having this capability.

Otherwise, anyone can just put a powerful engine on a Third Gen fighter like the MIg-21 or F-100 to magically increase their STR/ITR to that comparable to the Fourth Gen.
