It's the AC313
A, which is the civilian version of the Z-8L. I
posted about this about two years ago, although at the time I didn't know it was based on the Z-8L because that designation was still unknown.
AC313A is an improved civilian variant of the Z-8. Bullet points are as follows:
- Optimized engine layout, reducing engine installation loss (?) by more than 3%.
- New high-performance engine with improved lifespan and performance.
- Can operate 200% longer when carrying an external load of five tons, with great-than-40% high-altitude carrying capacity.
- Implemented HUMS (Health and Usage Monitoring System) and anti-icing system, improved safety, now capable of operating across all terrains and geographies.
- Better ease of maintenance, improved efficiency, reduced life-cycle cost.
