一种小展弦比高升力飞机的气动布局研究.pdfPerhaps someone can reference Dr. Song's 2000 paper on this subject? If anything, his analysis of the J-20s aerodynamics should be the most authoritative one on here ...
J-20 is NOT a close coupled canard.
What he said is true. Seems you are the one has little experience and knowledge about jet. Rafale is close canard actually.I stopped reading after after this...

Why didn't China think of developing a single-engine version of the J-20? That was amazing
F-135 paid a price for higher thrust, which is much higher bypass ratio.Single engine has much shorter range and capability unless China has F135 it can use. Maybe after WS15 has 10 years of proven service like WS10, they may put WS15 onto a single engine fighter like J-10 now uses WS10.
I think some people have confusion over what a long arm and close couple is referring to. It is the moment arm along the center of gravity or physical centroid models. Couple refers to the combination of forces to create motion. Close vs long is in the moment arm. At least this is how I understand it with English being second language and my engineering understanding of these mechanics. Perhaps the aerodynamic definitions are different to my assumptions but google indicates Eurofighter is long arm as well. So I suspect I am correct.
China has demonstrated an apparent capability to develop stealth fighters. While Chinese aviation technology should not be underestimated, this essay strikes a cautionary note. Using historical examples from Argentina, Egypt, and India, the author contends that Chinese stealth fighters are being unveiled in part to highlight China’s arrival as a global power; however, future Chinese jet fighter development will be hindered by technical challenges such as the development of indigenous engines—not to mention advanced weapons and sensors.
Argentina, Egypt, and IndiaAnyone want a laugh??
Here's quite a strange link published by the USAF university:

... with a most "interesting" View attachment 640749 analogy and strange conclusion:
Well ... what relevance do have some historical examples from Argentina, Egypt, and India with China's ability to build stealth fighters??And I'm indeed shocked View attachment 640748 since this is really written by someone working for the USAF University!?
It reminds me to a tweet I saw some weeks ago from the US Naval institute.

Pure pity that they fell to such a low level.
When one sees more messages like these, then one knows they are facing difficulties to lead… and the confidence is diminishing.Anyone want a laugh??

Hopefully the top brass of the Pentagon does not share this mindset in the slightest ... otherwise I worry for the US military. Underestimating the Japanese in the early stages of WW2 and the Vietnamese air force proved extremely costly ...Anyone want a laugh??
