No…it’s because they wanted a design that had excellent maneuvering characteristics in subsonic, supersonic, and transonic regimes, and found that optimizing the vortex coupling from a canard delta with lerxes gave them the best lift drag ratios in all flight regimes compared to other configurations. This increased flight control complexity but it’s a penalty they chose to eat to attain a competitive design to the F-22.

Dude, you clearly failed physics in high school....
And you got it wrong on the designation.....the swept wing (F22, F35, most jets) is designated as stabilizing aero config, whereas the delta-canard is referred as destabilizing aero config. Now you tell me, which approach should be termed as conventional? which approach demanded more on flight control? Not to mentioned J20 incorporated fairing into the equation to generate more vortices......on top of the one generated by canard alone...
From pure fighter kinematics, delta canard is arguably the most optimal configuration available.
Now it isn't exactly liked in 5th gen fighters (with a single exception to confirm the rule) for a very well-known reason, but Chengdu knew this reason no worse than everyone else.
As we know, the end result satisfied them, satisfied the commission during the competition, and satisfied PLAAF.
The Chinese government has always been horrific at PR. Yet another example.
Shaking my head here too. They managed to develop the J-20 successfully without meaningful accidents that we know of and a decade later they are still secretive about an even more conventional fighter than the J-20.
Absolutely disappointing for us military and aviation enthusiasts... At least we got the KF-21 media coverage to scratch that itch a bit.
I never understood this. It's not as if there's some 'rule of war' that one side cannot use equipment based on designs of the other side. Where China clearly has based its designs on foreign kit (e.g. Z20, J-11/15/16, H-6K, Z-9, many others) - whether by fair means or foul- then they've saved themselves billions and billions of $$$ in design & development costs - what's not to like? In other cases it's clearly a matter or form following function - the way pretty much every current or planned 5th Gen fighter (except of course J-20) looks like something between F22 and F35 is because they're all trying to meet similar design requirements.
Despite having a totally different planform, the J-20 is constantly being accused of being copies of F-22 and F-35. China's hypersonic missiles are also accused of being based on stolen American tech even though such tech doesn't exist in the US yet. Such accusations are not dependent on what the Chinese do as they are reflections of the deep seated racism of the accusers.
Maybe PLA uses 5 to refer to carrier based fighter aircrafts (e.g., J15). Perhaps PLA sees J35 to be one “generation” ahead of J20 in manufacturing techniques or strategic significance (that it deserves to be in the 30 category instead of 20) or it represents the next evolution of PLA Air Force planning so it is J35 instead of J25.
The 20 series like Z20, Y20, J20 (except for H20) call came out during 2010-2020, J35 will enter service between 2020-2030, it is one decade later, so being in the 30 category probably makes sense instead of being in the 20 category.
Finally who cares if its name is similar to F35, even if all Chinese war machines are directly copied from the US, as long as they can defeat Americans in wars that’s all that matters. These things are not made to score internet points, they’re used to kill. For example, you can laugh at PVA’s military equipment all you want but they killed a lot of Americans in the Korean War and that’s all that matters.
People need to do a bit of introspection and decolonize a their worldviews, what white people or Americans think and feel is meaningless. I wouldn’t care if my dog thinks J35 and F35 looks alike, unless I want to obtain approval and validation from my dog, but that would be stupid.
