Logically speaking, let us say the claim contains components A, B, and C. If component B is wrong, then the claim is wrong, which you have noted. But it doesn't imply that components A and C are necessarily wrong as well.I'm sorry but Minnie Chan literally claimed that the J-20B just entered mass production with a thrust vectoring AL-31?
The claim that I'm paying attention to from Minnie Chan is that there's a J-20B which is intended to be a J-20A with TVC nozzles attached and integrated into the flight control system, and that the J-20B is going to be mass produced.
I'm treating this not as blatantly wrong, as other posters claim here, but as a plausible claim from a low-reliability source that needs further substantiation.
I also don't see that it can be assumed that the Chinese aren't running AL-31F engines on the J-20B, even though the WS-10B is considered ready. If you look at the rear design for the J-20, the J-20 has a significant problem in that its nozzle placement isn't optimal for TVC, not because the nozzles are adjacent, but because the nozzles are recessed by the rear ECM pylons.
The WS-10 engine, compared to the AL-31F, as can be seen on this CJDBY thread:
is shallower and shorter than the AL-31F. This means that there needs to be substantial modification to move the nozzles further outward from the main body. Since the AL-31F engine, in contrast, is longer, there is less modification needed to move the nozzles outward.
In either case, it's a goddamn Minnie Chan claim. Plausible, yes, but needs further substantiation. Simply because it comes from her doesn't mean it's right or wrong, it just means it's unreliable and requires further evidence.
