If I remember corrrectly, a few years ago, i think there were pictures of the Y-20 with WS-20 engines. The ws-20 must be quite far along in its development if all these pictures and 'rumours' are correct.

No. So far no WS-20 was seen on a Y-20. I am not even sure if any was fitted already.

Just found the photo actually came from the last Zhuhai show, someone forwarded tons of pictures in a chinese forum and I picked three of them post here.
It looks like more a general aero engine control system demo than an actual model to me.

It is confirm in flight testing so I doubt it is just research development of control system because flight testing is expensive For R&D they just do ground testing[/QUOTE]

They're probably trying to figure out the FCS for TVC.
Is the engine model WS-13E or its derivative?Just found the photo actually came from the last Zhuhai show, someone forwarded tons of pictures in a chinese forum and I picked three of them post here.

Put TVC on WS-13 for J-31 makes more sense as it is more useful in a conventional aircraft. WS-15 on J-20 may not need TVC at all (if PLAF want to use every drop of the thrust), but a bonus if post-stall performance is desired.
