Interesting bits of info from 施佬
Z-8, Z-8A、J、JA、JH、S versions used WZ-6A engines (1640 horsepower)
- Z-8K、KA、KH、WJS、B versions are using PT6B-67A engines (1448kw, 1968 horsepower), composite rotor blades, new avionics
- Z-8G, L and various Z-18 versions are using PT6B-67A engines (1448kw, 1968 horsepower), redesigned fuselage, lots of composite material used, FADEC, upgraded avionics and reduction gears
- AC313A is designed with WZ-10 engines (1600k, 2175 horsepower), different engine and reduction gears placements to improve power efficiencies.
- Z-8C (for 075 LHDs) are equipped with WZ-6C
PLA is in the process of replacing existing fleet that use the PT6B-67A engine with WZ-6C engines to reduce dependency on foreign tech. WZ-6C’s power is about 10% less.
PT6B-67A gotten off existing fleet will be used for parts to support the Z-8G (高) and Z-8L fleet.
I was hoping Z-8L will be mass produced. Damn. PLAGF will have to wait for the completion of AC313A for the mass production of 13-ton class helicopters.
