I take it, that the insinuation is that this is engine is a large bypass turbofan, possibly WS-20.

Certainly nothing to particularly discredit it, but nothing too much to support it, unless the OP is someone with a good rep.

I too am uncertain about the OP, thus the 'mmmmm'... Since many a good 'leaks' have started in a similarly vague manner, I just couldn't resist. :D

Haven't we already seen one of the prototypes sporting a WS-20? This is old news then!

No, the prototype Y-20 has never been pictured with any engine other than the D-30.

However, a different engine was seen with a CFTE IL-76 test plane.

There seem to be some changes / modifications added to the wing, spine, since the last image ... :confused:

中国大飞机进展惊人：装上国产发动机震撼全世界

　　“运-20目前进展比较顺利，一切都在计划之中，试飞过程基本反映了设计师们的意图。”3月3日，全国政协委员、中航工业一飞总设计师、运-20总设计师唐长红院士接受了新华社记者的采访。唐长红在采访中表示，正在试飞的运-20已经实现了最大起飞重量和最大飞行高度；即将配备于运-20的国产发动机目前也进展顺利。

“试飞的成功验证了运-20的‘优质’。”唐长红透露，运-20在试飞中已经实现了最大起飞重量和最大飞行高度，飞行员描述运-20的飞行感觉是：飞机很平稳，具有优良的气动特性、起飞着落特性、承载能力等；至于外界关心的发动机问题唐长红表示：“即将配备于运-20的国产发动机，目前进展比较顺利，取得了很大的进展。”

　　由于目前国内在大涵道比发动机领域的研制能力不足，因此有关研发部门采取了两步走的设计方针。首先由中航成发和西发在D-30KP发动机的基础上研制涡扇-18，然后由中航商发在涡扇-10的核心机的基础上研制涵道比更大的国产发动机——涡扇-20。从目前网络上流传的照片看，目前已经试飞的两架运-20依旧在使用俄制D-30KP发动机，网上也有传闻称成发和西发已经开始在涡扇-18的基础上研制性能更好的改进型发动机涡扇-18A。有网友预测，运-20在服役早期将以D-30KP、涡扇-18以及涡扇-18A发动机为主要动力，在未来将装备涡扇-20发动机。

Chief designer of Y20 talk about Y20 and WS20 and they also mentioned the WS18, WS18A and WS20.
