Any idea on what kind of powerplant the Chinese Apache/Z-21 might be using?

Best guess would be the same powerplant as the Z-20 (i.e. two WZ-10 turboshaft engines), given their MTOWs are pretty much in the same category.
yesterday soyo posted..
Harbin Steam Turbine-Harbin Electric's new patent shows that the entire CGT25/30/40 series (including marine models) are all three-shaft gas turbines.
Three shaft is way more technological complex design as compare to two shaft.
Isn't that a bit underpowered for a supposedly heavy attack helicopter?
Nobody uses attack helicopters to dogfight.
Also, the WZ-10 turboshaft engines on the Z-21 has a rated power output of ~1600 kW. Meanwhile, the most recent T700 turboshaft engine variant on the AH-64 Apache has a roughly similar power output of ~1400kW. Both of these attack helicopters are in the similar 10-ton MTOW category (with the differences likely within half a ton).
Either way, newer units of the Apache will receive the more powerful T901 turboshaft engines with ~2200 kW of output power later on, but that's beside the point. Just take a look at all the attack helicopters from other countries that are in the same MTOW category, and the rated power values of their turboshaft engines don't really deviate too much from the mid-1000 kW category.

Apparently there's also a AEP380 turboprop engine with a purported rated power of 3800 kW? Perhaps this one is a derated variant of the AEP400/AEP500/WJ-10?

Even the C919/c919-800 have a domestic market to fulfill in the thousand... A nice stepping stone.
C929 have a domestic market in the multiple of thousands.
Exporting is nice but cutting up the domestic market from Boeing and Airbus is already a big thorn in their side.
Asian market is one of the biggest market out there and you need incredible facilities just to fulfill all the demands there.. No need for American ot European markets to pump out hundreds of airliners a year anyway. Engines production need to follow the curve.

What's the latest round of news/rumors on Chinese turbofans though?
