    Here's an interesting thought: How will China test WS-19? There are no twin-engine fighters in the PLAAF that are suitably sized. JF-17 is single engine so it would be even riskier. The most suitable fighter would be MiG-29 but China doesn't have any. So are they going to strap it onto a Y-20 as 1 of 4 engines for altitude testing and then drop it right into the J-31 naval evolution? Will they go full in with 2 WS-19 or WS-19 + RD-93? Will RD-93 still fit on the enlarged naval version? I know nobody has the answer but any thoughts?

    What about swapping out an engine on the FC-31 1.0 or 2.0?

    That post is dated November 1, though, do you have the link to the original post?

    Well, it's not like either of those 2 are mature and I don't know if the WS-19, designed for an aircraft that is supposedly 30% larger/heavier, can fit into an RD-93 bay. I would think that they would make use of the greater space allowance to design the engine a bit bigger to get more even more thrust on top of what's afforded by a design improvement.

    I've considered that they might make shims to fit them into a test Flanker that is stripped down for extreme light weight (but you can't shim a larger engine into a smaller bay for the V1 or V2). Su-27SK flew extremely well weighing 16.4 tonnes with 122.5kN AL-31F's so depending on the WS-19 thrust of course, they might not have to lose too much weight to make it work decently.

    I think FC-31 would be a good choice, like WS-10 on J-11.

    If the engine houses on FC-31 were prepared for target engine bigger than RD-93 and WS-19 is the target engine, both are pretty certain, then there is no problem of putting one WS-19 on FC-31 and keeping the other RD-93 as a precaution. The target engine was never RD-93, so the dimension and fitting of the housing must have taken that into consideration. This is the same thing as J-20 and WS-15 in the future.
