Interesting ... in another post he also mentioned something what sounds like the "final maiden flight for 2023 was performed on 28. December" and something I read already a few times but I do not understand: What is meant with "the "2323" balanced production goal"?? The 2323 is strange?!

2323 is the current quarterly production output pattern pursued by AVIC. It is used to be 0118, like Q1 for everyone to relax and Q4 is when everyone has to work overtime to deliver 80% of the whole year’s goal.

Pardon, but I do not understand the meaning of 2323? ... and what then was 0118?

It means for a given year , say 2023, Q1 finishes 20 % of the whole year’s output, Q2 30%, Q3 20% and Q4 30%. In this way the output and work load are balanced.
Previously, 0118 had been the typical Chinese state run factories output pattern. only Q4 ( October, November and December) is the time to rush to produce

posted New Year post with "CB10280".

IMO the numerical system is consistent with the logic of "each batch consists of 40 airframes after Batch No.7" but it is very weird that no photo proof ever surfaced on social media meanwhile the number keeps going up.

Not exactly related, but in another post he commented that there might be a chance for 2D TVC for J-20A's after all??

Top to bottom:

How do you know it wasn't installed already (he was replying to a comment about 2D TVC on WS-19)

It's installed on WS-19 already? Really? Shame it isn't installed on WS-15.

Who says it wasn't installed

Orca inferred from Director Yang's (J-20 designer) seminar that the J-20 doesn't need 2D TVC, although Shenyang Aero Engine's study paper proved that WS-15 with TVC had excellent results in ground tests.... (not a part of the translation but personally I don't 100% agree with Orca's interpretation)

Well, it was the J-20. Didn't say it was the J-20A

It’s a joke. He don’t mean that.

Yeah, he posted CB10288, there must be something on with my eyes, Jesus. Then I am confused again how they made their numerical system again.

I mean, CB10288 would still be consistent with your "every batch after batch number 07/overall batch 8 has 40 airframes" theory, because batch 10 would have airframes 280 to 319 (edit: or would it be 281 to 320? I forget)


Actually never mind, I see what you mean now.
If it was 40 a batch after CB07, then CB10 should only go up to 280, rather than 288.

Tbh all of these CB numbers being thrown around on weibo really make it rather difficult in terms of picking and choosing which are reliable and which are not because many contradict each other.


If CB10288 is legit, and if CB09234 is legit, then one possible explanation is:
CB00-07: 20 airframes per batch
CB08-09: ??40 airframes per batch
CB10: ??50-60 airframes per batch

...who didn't mean what
If its as in who knows if it's installed, and who knows if it isn't installed, I mean, only time can tell.

TVC's application isn't only limited to supermanuverbility anyways, especially 2D. You have IR signature benefits, and since (judging by the delta-canard and body design) J-20 is more supersonically optimized, 2D TVC provides another mean of pitch (and maybe even roll) maneuvering without relying on control surfaces, aka RCS optimization.

Besides, I couldn't recall Director Yang's seminar clearly, but I remember he didn't specify whether it's 2D or 3D TVC, and he's saying it on a maneuverability standpoint. If anyone have the seminar I would love to check.
