A particular low BPR (afterburning) engine:

"...Results show that when the flight Mach number was in the range of approximately 0.98–1.02, the total thrust increased sharply with increasing Mach. At an altitude of 8 km and Mach 1.42, the engine's maximum total thrust reached 123.78% of its reference ground test value. At 11 km and Mach 1.69, the relative thrust was 119.70%, both exceeding the corresponding ground-test thrust under the same operating conditions."

Given the supersonic performance, this might be the WS-10C/C2 or even 15. Given the date, I'm leaning towards the former.

What also causes the many WS-10 variants is the position of the gearbox and accessories.

I wonder what the J-20 uses? Top or bottom accessories on its engines?

Bottom. Hence why the WS-10B and C are allegedly not interchangeable with WS-10A and D.

What did you mean by "beer belly" on twitter? "Fishnet" i assume to mean ribbing from 3d printing?

See how on the "5th gen engines" the casing around the HP spool/combustor is kind of "inflated" to a wine barrel shape? I call that a beer belly (and you can also see the "fishnet" ribbing I described):

(You can kinnnnda see it on the WS-19's demonstrator)

(This is allegedly the AL-51F)

To be fair, the WS-10 family uses composite casings and wouldn't have the fishnet ribbing as a result. But I want the beer belly too
