Chinese Engine Development

AEP-500 has 8 blades but military variant WJ-10 will also have 8 blades ?? this one nobody knows.
WJ-6C has over 3200KW maximum thrust
AEP-500 has 5000KW maximum thrust
this engine has to be somewhat AEP-500 related or completely new variant of WJ-6 family.. it couldn't be a totally new turboprop engine outside AEP-500/WJ-6 because this doesn't make sense..
The engine cowlings look similar to the one used here in MA700.
I believe this is the case. The aircraft is engine testbed to certify AEP-500. There is almost zero chance that it is related to WJ-6 because the much larger intake size and arrangement meaning air flow rate is vastly differnt, so are the compressors etc. etc., has to be a different engine.
The 8 blades concept was from PW150C, I believe that when AECC made their poster they took the same idea of propellers for AEP500. Anyway I think number of blades is not part of definition of an engine but part of aircraft.
Here is CAAC news depiciting the PW engine.
Saw some comments on Twitter and Weibo recently which suggested/claimed that the new turboprop engine seen on the Y-8 testbed platform could be a derated variant of AEP-500, known as AEP-400. Following the namesake, the AEP-400 will have a power output of 4000kW instead of 5000kW.
The AEP-400 is said to be meant for:
- Y-8;
- Y-9; and/or
- KJ-600 (either).
Whereas the AEP-500 is said to be meant for:
- MA700;
- KJ-600 (either); and/or
- China's next-gen medium airlifter (namely Y-30) to succeed the Y-8/9 family.
Is this anywhere true/likely?

i have heard this AEP-400 engine but hardly any authentic information i get about this project. the biggest hurdle about ''Turboprop/Turboshaft'' is lack of authentic information due to nature of the project. when it comes engine news, turbofan stands tall.
so it is even become more difficult to get any information regarding these projects.
but one thing is confirmed. the tested machine is next generation high thrust turboprop engine and is in final stage of development. airborne testing.
this was much needed engine for PLAAF/PLAN in order to replace older WJ-6.
I'm not sure if AEP500 is still a thing. An official report on a 2024 meeting on materials certification only mentioned AEP400 and not AEP500. Given that the plan was for AEP500 to receive certification in 2028 it should have been discussed. Perhaps they're only expecting flatrated applications so they are only going to certify the engine for flatrated uses and renamed it AEP400.
