For pure research without practical implications, this is expensive and not very useful. I.e. there's some overflow of data into normal jet CTOL performance, but you may as well make a simpler demonstrator just for that alone.
What are the odds, that what we're looking here is not a fan, as people are saying here, but a compressor (stator blades not depicted)?
RAAF F-35s are A models.
My point was obviously broader than just the RAAF birds -- this whole episode at least gives some credence to those earlier rumors, i.e., something must have clearly happened. But your take is valid too...
Rather than investigating potential embezzlement, shifting the blame onto China would also be a convenient option.
There is no indication of any engine related items being involved. Please do not add your own unfounded speculation here.
I see you have absolutely zero self-awareness...

"but you can bet that a good chunk of those other components are going to be engine-related" is unfounded speculation. You can call it something else if you want but that is what it is.
I am sick of people making comments without any facts or true knowledge. Using a Twitter post as some claim of evidence is laughable at best. I challenge you to find any credible evidence to back up this BS Twitter claim. As someone in the industry and having particular interest in this area I can assure you that they are utter garbage.
Actually that only shows your bias (as proved elsewhere on the forum, but that's another issue altogether). Besides i doubt you or pretty much anyone in the west really has any idea what the chinese got (or didn't got) F-35 wise. However the near-certain work on an F-135PW-600 like engine as well as iirc some surprisingly similar engine parts, well as a ruomured F-35B equivalent in the works certainly point to to some developments we might not be privy off and likely never will. For all we know they might have smuggled piece by piece an entire F-35 or at least big chunks of it, which is a hilarious thought, but again i doubt anyone on these forums has any way of knowing either way (if ever).
Could be anything from seat covers to an engine. I'm guessing it's on the lower end. But keep the dream alive.
Well how else would they be able to build one? Gotta steal it somehow.
These are standard Chinese government-style tender notices listing the project title, location (Beijing), type (招标公告 / bidding announcement), and release date."
