I guess this means that WS-19 is for export. Previously there was a vicious rumor that China doesn’t feel safe about exporting WS-19 with J-35E and would offer WS-21 instead.

Is the infocard an official one from AVIC? Or merely speculation by the hosting Singapore organisation?

I admit its difficult to imagine the WS-19 being offered for export at this time. This is the medium weight class equivalent of the WS-15 being offered for export, not to mention its rumoured to use WS-15 derivative technologies. It should be expected that Western intelligence would get fairly accurate specs rapidly after the first export sale, so would it be wise to have them know so much about the engine/s that will power China's late 5th and early 6th-gen fleet?

We know the WS-21/13 (?) is a mature engine, so its matches with the WS-10 family and therefore has precedent for export, and should be more than sufficient for any customer that needs J-35AE just like WS-10C is sufficient for (even if not fully realising the potential of) J-20. Ultimately its the stealth of J-35AE that will be its selling point, not its interconnectivity (China is only selling J-35AE platform and not the entire system) nor enhanced kinematics from a top-of-the-line engine.

25000 lb is 110kN. That is a little or even notably higher thrust than I expected. So, I don’t know how accurate that is, but quite interesting.

It’s in line with leaks about the engine for the last 2-3 years. Apparently they could have pushed the thrust to 120 kn but decided to preserve service life margins instead.

yes, I always thought the earlier rumors of 9800 kn didn't seem to match where China's AeroEngine supply chain is at this moment.

You can always start off at around 110kN and then increase it once the reliability issues get sorted out. We've seen them push WS-10 series along quite a bit. Not too difficult to see similar improvement here over time. And then, you have a pretty good engine option for UCAVs.

I think they’ve definitely gone from “push thrust first” to “prioritize service life first” in their choice of performance calibration for production engines over the last decade, which itself should be a pretty good indicator of growing technological confidence.

From the style of writing, and ended with DD, it is not typical article in Mainland Chinese style or that of AVIC. I would bet it is from one of the Singaporean journalist or writer.

I would say he/she just wrote what we already know and discussed heavily on our forum.
