Which century are you from?
Jokes aside, I have a nice collection of GIFs of supposed WS-series thrust vectoring engines.
Apparently the WS17 and WS13E engines are also progressing.
I would not be looking for a 15:1 Thrust Weight ratio jet engine in the near future. That capability is still beyond the current state of the art for fighter/attack jet aircraft.Whether a 15 T:W engine could be installed onto the J-20 would really depend on the dimensions of the engine, so it's really impossible to say for now, but I do think that by the time China can make a 15 T:W engine reliability may no longer be the kind of issue where it would necessitate testing on a different design first.

I believe the current highest thrust to weight ratio for any jet engine that went into full production was the Pratt and Whitney F-119 afterburning turbofan for the F-22. It is right around 7.95 T:W and the F-22 of course carriers two of them.
The Pratt & Whitney F-135 that is going to power the Joint Strike Fighter (which is not in full production yet) has an 11.35 T:W ratio. So, within a couple of years, there will be a production T:W ratio engine of 11.35. Maybe two of those will ppower the FXX prgram in the future.
I believe the prototype for the Shenyang/Xian WS-15 has reached something like 9 T:W, with a desired goal of T:W of around 10 for production, which will be very good actually.
The Russian Al-41F that was prototyped on a Mig-25 testbed in the late 1980s, and then later flew on the cancelled MIG Project 1.44 MFI in 2000. It reportedly had an 11:1 T:W ratio, but it never went into production.
Once a higher T:W engines is produced, it will be mated to an airframe that was designed to take advantage of it. Do you think that the J-20 is designed for that? The F-35 may be getting close, but it was not designed with a 15:1 T:W ratio jet engine in mind.
Personally, at this stage, I will be happy to see China go into full production with a current state of the art angine for the J-20, J-15, J-16 etc. in the near future. The WS-15 appears to be that engine at this point.
The article only drops those designations on the side. It primarily talks about the progress in machining tools. When this article came out a lot of people were asking questions about it in the Chinese bbs, but there was nothing else. Very mysterious.Anyinfo in what class of thrust they are ... maybe even what aircraft is planned to use them ??
Thanks in advance,

I have always believed F-119 has a T:W ratio of approximately 10 and WS-15 has been targeting F-119 in that respect. It is said WS-15 is not there (T:W = 10) yet, but is close (9). Are you using a different calculation of T:W ratio for F-119?

I read somewhere that USAF will continue using F-15Es well into 2030, and even the most optmistic data point to an IOC date of around 2030. By then the majority of USAF fleet will consist of the 190 F-22s and thousands of F-35s. Given the technological gap between PLAAF and USAF, which I'll generously put at a decade and half, it isn't inconceivable for later block J-10Bs and J-16s to remain in service by the late 2040s.
There is also precendent of fighters like the F-14, which initially used a relatively underpowered (for its size) TF-30, switching to the much more powerful F-110 once it was ready. In fact, I think it is a great idea to use the J-20, by then a mature platform, to test the operational capabilities of the new engine for the sixth generation platform, assuming that China is comfortable enough by then with engine tech to attempt something as crazy as this.
