I stumbled across the no. 15 in the title, which is always most interesting, but it seems more likely related to the number of engine stages than the WS-15?!



= A design of a 15-stage aero engine with a thrust ratio, which uses a new principle turbine disc to greatly improve the single-stage boost ratio

Anyone with an idea what kind of engine this is?

Might be the variable cycle engine you guys were speculating about.

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.
