Just report Gadgetcool, he just returned from a ban for trolling. This guy is obviously a troll, posting nationalreview articles on J-20 depending on Al-31 engines. Is this guy clearly a troll?

Great to see the WS-20 on the Y-20. I think for the likes of CR919 & 929 though the options should remain for the customers to chose the engine, i.e. maintain GE & whatever else in the market as engine options along with the WS-20. That way it keeps the carrot in play for western corporations to continue to work with Chinese companies to work out the kinks in these aircrafts in the Chinese market first. I mean, end of the day, these are essentially first and second gen wide body commercial airliners for China, and there is no shortcut to catch up. It'll keep the ecosystem open and competition alive much like what Tesla is doing to the electric car system. As long as we have demonstrated that we can achieve technological advances in these fields, there won't be no shortage of corporate suitors lobbying the western governments to lift the sanctions/restrictions for the pieces that China has already developed so they can gain a bigger piece of the commercial pie. As big as China is, it is still in its best interest to be able to cooperate with the rest of the western world on technologies. Its not a zero sum game between having the technology to build everything by oneself, or pick and chose components from others for the best commercial gains for oneself and their customer.
WS-20 will jump-start ACAE CJ1000A program. Both are the same type of turbofan engine maybe improve fuel efficiency, reliability, and maintainability.

Wait, wait, wait.... you're not someone to speculate like that, unless you've already got a whiff of it.
What? It was in official news that the first CJ-1000AX completed assembly in Dec 2017 and fired up in early 2018. That it is in testing now is pretty much a given.

What we don't know is just how many specimens they have assembled, and how far the certification process has progressed. Some expect it to finish around 2025-2030.

Now that you have resurfaced, do you know when it will be tested on an aircraft?

The CJ-1000A uses foreign parts guys. If China really gets isolated it has to rely on the WS-20.
I agree that it makes little sense to use the C919 as a tanker. The C929 would make much more sense for that.
Given the timescales involved the C929 will not be available any time soon. Perhaps even only in two decades.
So it is plain to see the Y-20 is the aircraft which makes most sense for this application.

The C919 could still be used for radar, electronics warfare, and sea patrol however. Similar to E-7 or P-8.
In those circumstances the WS-20 engine would be good enough performance wise. E-7 and P-8 use CFM56 engines.
The question is the reliability of the WS-20 at least in its initial versions.
I thought the CR929 is targeted for introduction 2028-29?

CJ 1000A use GKN LP shaft for the prototype. But I am pretty sure that by the time to production model ready it will be replaced with domestic one or JV. The same apply to other foreign made supplier
China is determined to built domestic engine It is included in the next 5 year plan.

China outlines push to develop domestic engine for C919 jet in five-year plan​

BEIJING (Reuters) - China will push forward with the development of CJ1000, a turbofan jet engine designed to power the homemade C919 narrowbody aircraft, the government said on Friday in its development plan for the 2021-2025 period.
It also aims to achieve breakthrough in engine technology for widebody jets, the government said.
