Maybe I didn't make myself clear, I said it is highly unlikely that WS-10B is not compatible with serial J-10, not that it is incompatible ;)

Not sure why You think so !?? ... We have already seen the WS-10A being interchangeable with the AL-31F in a Flanker (see J-15 prototype '554') and I can't think that this is only a specially modified aircraft to test both engines. As such I assume the WS-10B can be used on a standard J-10B with only minor modification and not like You suggest via a completely redesigned internal structure. I can't think that SAC has an AL-31F and WS-10A-structured J-11B on the line and the same also for CAC.

Most likely the WS-10 was designed from the beginning with a possible engine-change in mind ... if that will be done is a different story, but stories that the WS-10 has a marginally wider diameter and won't fit a standard fuselage is non-sense.

IMO the latest AL-31FN series III is simply now a bit more reliable and has a higher thrust than the now available WS-10B and that's the reason for the J-10B still being AL-31FN-powered.
There are couple of things you have to remember:
  1. 554 is a prototype, as such it can receive changes that are cost prohibited to any production aircraft.
  2. A smaller object can always be fitted into a larger hole, but a smaller hole can't receive a larger object.
  3. Air intake and engine work in unison. Mismatched intake and engine cause problems, which costed SAC dearly when they first fitted WS-10 onto Flankers.
  4. Changing the type of engines on one Flanker out of hundreds out there is hardly a convincing argument that AL-31FN and WS-10B are interchangeable on the J-10.

So how many J-10Bs of this 1st batch? and who is going to get them?

Hey, that's the million $$ question I would have to be answered since weeks !

As far as I know up to number 1-48 has been spotted - as such 48 aircraft in batch 01 - and following the few blurred images available, the first unit to get the J-10Bs is the 170. Brigade within the FTTC (due to mots likely 78x1x - serials) and a second batch of J-10Bs were ready to be delivered to a true operational unit. This however is still unknown even if Huitong claims this to be the 4. AR / 2. AD due to maybe

- serials ... however I'm a bit skeptical and this very blurred "3" could also be an "8" making the 7. AD also possible.
