I care less about you banning me, as long as I am right, and there are more forums I am happy, any way math does not lie, a bank angle in a turn close to 80 degs means 9Gs, it means corner speed.Can you please stop with these stupid analysis? They are all based on the premise that they are showing the full capabilities, which is plain wrong.
The Chinese have no intention to reveal any notable true capabilities, there is no intention for chest-bumping with hyper-fancy manoeuvres like the Russian's do at MAKS.
All you can deduct from this display is the PLAAF political will to show it to the public and as such it's confidence in the WS-10C.
Anything else like turn-radius, speed of climb, thrust to weight ratio, manoeuvrability and whatever MUST be WRONG, since - in Germany we would say: "Der Pilot is mit angezogener Handbremse geflogen!" - this was just to show the J-20 flying, and not to impress the audience or any armchair analyst!
So please stop it.
Can I say the exact Turn rate of J-20? no of course not, but by looking at that bank I can see it is turning tight, and is a better aproximation by method than just saying "we can not know" , I am using math and physics.
And I have used known data easy to use, that turn on the picture shows a close to 90 degree bank, that approximation by bank angles is a much better method to guess the real capabilities by using physics, now you might think it is stupid but the reality the bank angle method is a scientific approximation since it is a fact that bank angles tell you the G load,
So do as you wish ban me if you want ban me i careless about it, as long as physics and math support me and there are other forums i careless.
