Chinese Engine Development

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

Are you sure it is a T/W ratio of 15 or is it 15 turbine stages?
Those two aren't the same thing.

推比15

The Chinese is unambiguous (Thrust Ratio 15). T/W Ratio = 15.

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.
