Sorry if this was asked before but does the yellow colour indicate that the aircraft is newly produced? If yes, then that should mean that production is currently proceeding, so then how many J-20s are produced each year and what is the estimation for the total inventory?

That's right, I used apologetics because its the most precise word to shed light on the purpose of this paper, (the paper is explaining and offering justification for Chengdu choosing the canard configuration over the more traditional lay out)....

Many observers have criticized Chengdu for using the overtly less L/O canard for pitch control, this paper attempts to nullify those arguments, and rationalize why the J-20 is configured as it is by using the F-35 fuselage as a NULL value and measuring only the canard and traditional stabilator for pitch, and their respective effect on the RCS of the platform.

The F-35 was chosen for two reasons, it is an excellent L/O configuration, and it closely resembles the J-20...

with this I will attempt to back out of this discussion, and return to the J-20 with this question... were there 4 additional new aircraft in the latest batch of "primer birds?"

But I think the main point of canard configuration is that you go to tailless (stereotypical 6th gen planform) very easily from canards. It's a compromise for supercruise, supersonic maneuverability, and so on vs base stealth (since the forewings are no longer blocking the edge of the tail), but it also offers the potential for TVC-based yaw control while still having back-ups should the TVC system fail.

Is it just me or does the engine look like a thrust vector variant with non-circular nozzle? WS-15?

If the axial symmetric nozzle is thrust vectoring, you would expect the fuselage fairing around the jet pipe to be pulled forward compared to those j-20 without thrust vectoring to give clearance for the nozzle to deflect.

also, I suspect dual axis axial-symmetric thrust vectoring nozzles would be difficult to integrate effectively into a highly stealthy aircraft. I think the Chinese clearly meant for Stealth to be fundamental to j-20’s mission profile, and not just an add-on afterthought. So I suspect they will either adapt single axis thrust vectoring nozzles optimized for stealth, such as that on the f-22, or none at all.
