If they call it "naval J-XX" I'm more inclined to believe it is a follow on to J-15. But we'll see.

The model number in paper says FWSXH....or FWS10H.

It is based on FWS10. So it has full digital control. The improvement is for increase of power during take-off.

Also in the paper, it appears FWS10 has a thrust of 12500kg (not rumored 13200kg). FWS10H has increased take-off thrust of 12800kg.

So how reliable is this? Doesn't it say that the WS-10H isn't ready? Then what engine is on the J-15?

The WS-10 is only 125KN? :(

That's still better than the Al-31F's 123kn.

But honestly we've heard so many differing news about the WS-10's thrust, and its status in general I think it's easier just to wait and see whether and which aircraft the PLA adopts it on. The fact it is on all new build SAC flankers is good enough.

Interesting that the paper says the supposed "H" version has an increased thrust... of only 300kg. lulz

Well as I am sure you would know, H stands for Hai, or sea/naval in the Chinese system instead of the abc of denoting bloak number as with a western system. As others have already pointed out, the naval version would primarily be concerned with things like anti-corrosion and even better reliability instead of just tryInv to get the highest thrust number.

If they had to use different materials and/or slight design changes, it may even has suffered a little reduction in thrust compared to the land based version.

correct me, it order to generate higher thrust, it will require bigger intake fan?

Jet engines are impulse engines.

Given the same amount of energy, it's easier to increase impulse by increasing airflow(mass) rather than the exhaust velocity -- at low velocity (take off).

At high velocity, the fans becomes less efficient for the same reason -- mass time delta v is less at high velocity.
