Thanks.
This is the patent application form of NUAA( Nanjing university of Aeronautics and Astronautics) for DSI intake smart skin technology. Back in year 2013.
Laugh the best as you can, that all you got left. Asok said J20 has smart skin on its DSI, you guys laughed at him. Asok said J20 will have domestic WS10b engine, you guys laugh at him. By the way , General Yingzhuo had proved on CCTV J20/ FC31 blk2 uses domestics turbo fan engine. When Asok said WS15 will have 200 KN max wet thrust, you guys also make fun of him. What a respect this forum shows to a reliable source!@gambit, every time you laugh at Asok proves how arrogant you are, and the denial you hold to Chinese steady progress. Then keep laughing, all speculation will turn to truth in the end.This...

...Is only a small sample of what the experts at the Pentagon uses to estimate aircraft performance using sensors data, whether the sensor is video, radar, or infrared. Of course, the more, the better the accuracy of their assessments.
Your friend uses only his eyeballs and bad math. Very interesting, indeed.

It's your stereotype of ' Chinese can't do what the west can't do', shall have a rest.
Regarding the variable DSI...
Clear enough ?
Bro, China was an empire and great nation for thousands years. We produced one thirds of world GDP back in Song Dynasty. Make our nation great again, same as Donald Trump slogan.Amen! Thanks Bro. for your support!
Sometimes, I think, being a one-eyed man, living among the blinds, is not really a blessing, but a burden. They will laugh at you, whatever, you told them.
They can deny and laugh all they can. We will have the last laugh. China's amazing progress in all scientific areas, undeniable, and unstoppable.
Thanks bro. Those are great observations. I am enjoying them.
Yes, that is AMAZING. Now I am now even more convince that J-20 cannot be using the AL-31F or an equivalent powerplants.
As I have always say, all the revealing signs are there, it is just that some of us are either to busy or still living in a state of denial.
They call you a fanboy because many of them hate the comparisons you provided but IMO numbers are numbers and facts are facts. That is why they called us, enthusiasts and while most of us cannot provide the absolute proof, how about them?
Even the real experts from the Pentagon are doing something, some of us are all doing today in their evaluation of the competitors' products.
Carry on with your post. Your findings and observations are all very interesting to many of us.

That's your philosophy of DSI, definitely not ours this time.
Either it be WS10b or WS15, it has enough power to make J20 maneuver agilely.Thanks Bro.! Your support is heart warming and very encouraging.
It all makes sense now, that China wants to hide the details and progress of WS-15 since 2005, after the engine core was ground tested. WS-15 is startlingly powerful.
If Pentagon's analysts or experts, can't figure out the ball park figure of J-20's Dry and Wet Thrust, after watching the airshow demonstration, they don't worth a dime.
The 200kN estimate for WS-15, is not all that amazing, considering, the F-35's F135 engine is classified as a 190kN engine, which could be a lot higher, once we considered, that figured is under-reported by P&W to keep the Max. Thrust performance, a secret.
And F135 was developed in the early 1990's, 25 years ago.
That is neither ours nor yours.
You forget another goodness of DSI, it enhance the stealthy feature of an aircraft by shield the turbofan blade form direct radar waves! The effectiveness of DSI compressing air reduce dramatically at the speed of 1.6Mach. Now it's very clear why China will increase the weight of DSI and make it transform at speed beyond certain threshhold.
The DSI was never designed for that purpose. If there is such a benefit, it is INCIDENTAL, never intentional.
Yes, it adds weight and complexity when you apply a smart DSI. But the it will perform extremely efficient when J20 make super cruise. You have to balance the gain and loss. DSI is a big plus in stealthy feature no matter it is intentional or incidental.
The real breathtaking arrogance and ignorance is yours.
