Would you please be so kind and add a summary in English or at least tell what it is about?

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?!

一种推比15级航空发动机设想，采用新原理涡轮盘极大提高单级增压比

= 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?

It just means the thrust-weight ratio is 15.

Ok, but thrust-weight ratio is 15 would hint towards the next generation engine or even a variable cycle type?

The TWR 15 engine should refer to the variable/adaptive cycle engine.
