i agree, but as i said it can be 2020 or 2018 or 2023, because expecting the jet to fly in 2018 does not mean it will, it is just a plan projection, the americans know by experience it will take then at least a decade to perfectionate the design to make it like the operational F-22

Regardless, there's your proof when you asked

can you quote an articel claiming the J-20 only will fit the engines in 2015 and by 2018 will fly in series production?

Sure we can say "oh they will be delayed," but that's irrelevant. You got your article which quotes it, GG.

The US projects an estimate of 2018. So does China. You insist 2020-2023. You asked for quotes, I gave you a few. Take your pick.

You're missing the point. If the current engine can supercruise (note, supercruise is not thrust dependent), they can test the airframe's supercruise performance. The behavior of the airframe during supercruise isn't going to change because they've installed TVC. We don't even know what engine it's using, so your opinion is as good as mine.

Yay America. Sadly, we can't extrapolate the development path of the J-20 using the YF-22 or YF-23. That's like trying to use the F-16 to figure out the development path of the J-10. There is little relation whatsoever. The J-20 will get the WS-15 when it gets the WS-15. Can it test supercruise without the WS-15? If it has an engine with a high enough exhaust impulse it can. If it doesn't it can't, but the point is we don't know and uninformed speculation won't get us anywhere.

*rollseyes*
China has been working on TVC and the WS-15 for years now. Your point?

my point is simple a rumour does not mean they have it now

The PAK-FA and J-20 were "rumours". We know it's in development because they say it's in development. Just like we knew the PAK-FA was in development and the J-20 was in development.

By your logic the PAK-FA will be stuck with the Al-41 because a better engine in development is only a "rumour".

Seriously???? The Chinese Air Force General He Wei Rong said, in a 2009 interview, that China's Fifth Generation fighter was in development and will be available in 8 or 9 years. If the J-20 is a Western definition technology demonstrator, or something China is not known to develop, what the heck will China use in 2017-2018? Buy the F-35 or T-50?

I guess the OP either has inside information or has way too much time on his/her hands to create another useless thread only to speculate further.

do not take me wrong a tech demostrator can be like the YF-22 or Rafale A, the time schedule can delayed and the final product change like the EAP was modified into the eurofighter we know today

i will suggest you something respect others, here we suppose to respect others, if you do not like the thread skipp it, but at least stop this typical useless way of giving no real information and bothering people, here i participate to exchange ideas, not to insult, be respectful please.

I think you're trying to make a point, but for the life of me I can't see one.
We've had word from PLAAF air force general in 2009 that the 5th generation fighter would enter service around 2018.
Yes there might be delays.
No there might not be delays. Either way you can't immediately assume all schedules will be.
The way I see the above argument is this "J-20 is a tech demonstrator which can be changed" ----> therefore "it can be delayed partly due to the need to make these changes". The problem is that J-20 isn't exactly a tech demonstrator like the YF-22 and Rafale A.

I think we're all fairly well mannered on this forum. But when you start seeing the same thing repeated over and over for sixty or so pages it kinda gets on your nerves.

----------

Mig-29, do you consider the PAK FA a technology demonstrator? Because if you consider that a tech demo rather than a prototype, then I will concede that J-20 can also be considered a "technology demonstrator" even though both aircraft should be considered prototypes.
(if anything PAK FA seems to need a bit more work WRT stealth shaping).
