Err no. These numbers literally look like the earlier version of the WS-10.
Yet the paper is published in 2025. And I'm fairly certain the early WS-10's BPR is >0.5. And skimming the actual paper it seems like a 3-10-2-2 (which is indeed a bit odd) while the WS-10 is 3-9-1-1.

BPR is superisingly high for a supposedly supercruise capable engine while TWR is very low
Not really. Pretty sure the EJ200 is supercruise-able.


Edit: my goodness... This might be some sort of ultramodernised WS-9.

Doesn’t mean it’s referring to a new engine. The bench test could be using an old engine. The paper might be summarizing the study of a bench testing analysis method for example. Would need the full paper to have a better idea. Do you have a link?

Edit: Another possibility is that it’s some unknown new engine (I’ve heard there has been some work in civilian supersonic engines). 3-10-2-2 makes it very unlikely to be the WS-19, but 2-2 turbine implies some attempt at recovering greater turbine efficiency over thrust.

What kind of aircraft these days still needs modernized WS-9? Large drones like Jiutian?

It's actually a some sort of WS-9. I imagined the 1 when I saw it.

Future CCA I suppose?

Would be easier if you just shared the paper…
Was just trying to get a link but gave up. Have it in blurry screenshots instead:

It's published under PLA/军工科技.
