I never noticed it is ... I actually thought it would be a misshaped bad CG showing a new Z-20 development, but it seems to be almost twice as heavy.
Z-XX - new Sino-Russian heavy-lift helicopter

Adorable Dolphin says the heavy heli is "soon, soon"
We should drop the "Sino-Russian" from the thread title.

Isn't there a 30kg/s class core, Mi-26's engines were only rated at 36kg/s
i was about to talk regarding Engine.. since they cannot get Engine from Ukraine and neither from Russia. so its obvious the Engines are locally produced. they had couple of turboshaft Engine projects.
the most interesting part is, which Engine they are going to use.
here are few options.

The AES-500 would be below the power level of the Lotarev D-136. Even if it existed.
8500 kW emergency power. 7500 kW takeoff power. 6338 kW cruise power.
Engine companies typically state the engine power level as the takeoff power number which is higher than the cruise.
Either they make it a smaller helicopter or go for a triple engine like the CH-53K.

5000KW vs 7500KW.
and we are not sure. they will use AES-500.
30kg/s class core machine is the ideal choice. let see
The Lotarev D-136 was based on the D-36 engine core used in the An-72. The D-36 got its power boosted and was used in the An-148 and Tu-334. Basically a C909.
Something like the AES-500 would be smaller but could be used in the Bell MV-75 tiltrotor clone as well. Sharing development costs. The AEP-500 derived turboprop should be used in the MA-700 and the carrier AEW&C aircraft.
You would still have to design a gearbox for it though and that is hardly simple.

all gearbox and transmission related work undertaken by AVIC Harbin.. AVIC building heavy lift helicopter so it's obvious they designed complex gearbox too.
