But from the progress of WS-10A, I will say the engine as AL-31 on J20 is very remote.
From J-15, J-11b to prototype of J-10B all using WS-10A. It's proven WS-10 has enter mass production and proven to be the workhorse of PLAAF/PLANAF. The engine on J-20 is very likely to be domestic tinker version of WS-10 series probably with upthrust /overclock.

you judging of engine type installed from progress made on Taihang family or from details you see on photos?
'remote' is when you try to convince me that engine with 11 radial flameholders and short petals is derivative of WS-10, not of AL-31
he was telling this continuously till winter

Rumor wise, it is NOT the baseline AL-31F with 123 kN you see in the Su-27SK. This engine is by Salyut. Same company that provides the AL-31FN for the J-10. Hui Tong once reported that it is a 'Product 99M' variant with close to 140 kN thrust. Remember Salyut also makes the AL-31FM1 (132 kN) for the Su-34 and they have several uprated variants proposed. Since then Hui Tong has changed it to WS-10X, but to me it seem logical that CAC and Salyut working together until the WS-15 is ready. J-20 flying with a Salyut engine as a stop-gap is not unbelievable/unthinkable to me. Just me 2 cents.
The problem is Russian are not interested in just selling few engines, especially a rival for it aircraft industries.
Remember China try to buy few Su-33 for evaluation instead of 50 reported by Russian and in the end , the deal break down.
I don't think China is interested to commit buying few hundred engines which they pose to use WS-15 in near future. That is precisely why J-20 using a Russian upthrust engines is very unlikely. It is even more unthinkable Salyut will work with CAC on engines issue. Salyut can't be that stupid to help a rival compete engines sales with them in near future?

I think you misunderstand. My poor wording. This is not transferring engine tech. The J-10 flies with AL-31FN, and it is flying in large numbers. The initial J-10 designed for WS-10 was modified for AL-31FN. Salyut came up with the gear-box changed AL-31FN etc etc. These 2 companies have been doing business/corporating for sometime.
If you look at the engine option :
* - WS-15 is at least 5 years away (Probably more). IIRC, maya said around 10 years from successful high altitude core testing (where is maya these days anyway?
)* - WS-10 only recently reached maturity (late 2009). Are they going to risk a brand spanking new 5th gen prototype with equally new higher thrust WS-10 variants?
you will be surprised, but that's exactly what Salyut currently does

I don't think so... Salyut only helps if there is long term benefit like J-10 project. But J-20 has comfirmed with fit with WS-15 engines in future.
A lot of times, media just trying to paint China can't do anything by themselves and need somebody helps.
Remember how media try to paint J-20 design is assigned by Mikoyan with passing Mig 1.44 blueprint or certain kind of assist to help China build the J-20 prototype. Because western media and anti-China group can't believe China has advanced so much.
Mikoyan quickly come out to clarfy all those false nonsense. It just sounds ridiculous how Salyut could have help a rival which will bite them in near future. China definitely has no intention to buy hundreds of their engines for J-20 in future.
Unless China paid billions of consultation fees but is impossible given China has refused to this kind of blackmail. With example of Su-33 cases and IL-76 transport military cargo deal which China decide to proceed with their own effort. Both project are highly critical to China military advancement given that they need IL-76 platform for more AWACS and J-15 for carrier fighter jet fleet..

Why not? WS-10 has already enter mass production and utilise in many platform and even make it into many prototype. J-20 is a twin engine jet. Running a twink higher thrust twin engines is still able to take certain risk. Engine lifespan is not critical in a prototype.
