It appears that the upcoming Zhuhai Airshow will display a lot of interesting stuffs (biggest suspense is if any sign of H-20 will appear). On the engine front, here is the relevant news.

They are going to show quite a few engines at the show. Some likely interpretations:

1. 太行发动机发展型。 Mostly likely WS-10C, already equipped on J-20. We know WS-10B on J-10C has a thrust of 144KN by official account. Since this WS-10 is an improved version of WS-10B, its thrust may be at least at 155KN, consistent with some running rumors. This has exceeded the original thrust goal of WS-15!

2. AEP500。This turboprop is the civilian variant of the military engines for KJ-600 and medium weight transporter Y-30. We've seen KJ-600 flying last year. This means this class of the turboprop engine is ready.

3. AEP60E and AEF100. While AEP500 is the 5000KW turboprop, AEP60E is the 600KW version. E stands for enhancement. AEF100 would be the 1-ton thrust turbofan engine, the corresponding military version would be used for UAVs.

4. Full-sized CJ1000 with nacelle display model. This is the domestic engine for C919. With nacelle it might suggest that CJ1000 is close to finalization.

Combined with other engine news (WS-20, WS-15, WS-19, WZ-16), strong indications that China is making progress across the board in aircraft engines.

They already displayed WS-10B at previous Zhuhai air shows. I think they are displaying the new variant with elongated feathers used on J-16.

What’s the source on the WS-10B thrust? Last I recall it was supposed to be 132-137 kN?

132kN-137kN figure is extrapolated from an article dating from 2016 that states that Chinese engineers have fixed several issues with the WS-10 engine and increased existing thrust by I think around 10%. Since the initial batch of WS-10 has a maximum thrust of 125kN after downrating engine power, the new thrust value falls in the ball park. I don’t think that they ever directly stated what the WS-10B’s thrust is.

Yes, WS-10B was displayed at previous Zhuai AirShow. This time it would be a new and different variant. It could be WS-10C on J-20 or the variant on J-16. Either one is likely, although I tend to think it's WS-10C. But we shall see.

What do you think the WS-10C's thrust is? I would guess 145kN is the lower bound since it would have to perform at least as well as the Russian engines it's replacing, but there are apparently rumours that it's as high as 155kN. If so, that's quite an achievement to add 20kN of thrust from the B to the C variant.
