It’s just a proof of concept engine, not even a prototype. Relax folks.

An unnamed marine gas turbine. Total output is 30MW, with a thermal efficiency of 40%. I'm not sure how old this image is or its veracity, although the Weibo poster shares a lot of legitimate information. The image seems to imply that it's used on or intended for the Type 055, but I can't vouch for that. Could be an advanced derivative of the GT-25000, although all open sources state an output of below 30MW (around 28MW). The red banner in the background says: "Chinese Academy of Sciences, Institute of Engineering Thermophysics, Advanced Gas Turbine Laboratory".
This likely means the turbine either operates at higher temperatures or has better energy recuperation.
40% efficiency is quite high for a marine gas turbine. This is important news.
Still I would wish they tried to increase the power output a bit to make it more competitive with latest Western gas turbines.

The fact that they can hit such high efficiency means that they can probably achieve higher output pretty easily too now. This is more a matter of design choices based on fit for applications than a matter of capability.
Posted on the wrong thread. This is the air force engine thread.

The thread title doesn't say "air force", and moreover, turbines on ships are often based on aviation variants. And finally, Z-10 and Z-19 are in the Air Force forum when in fact they are in service with the army. The same can be said about the Z-20 thread. In other words, categorization here at SDF is not a precise science, as many platforms share technologies and components and are used across many service branches. If you can think of a better classification system, be sure to let the webmaster know.
P.S. I had already cross-posted this in the Type 055 thread before I shared it here. Happy now?
Well, Z-10 and Z-19 are in the service with the army but they are still aircraft, so OK, i would say that this is the aircraft engine thread so this is off-topic posting. Turbines on ships arent necessarily based on aviation variants.
And no, im not happy.

Let's agree to disagree.
