I would like to know the number ?

I would like to know the number ?

Hopefully we will see one in active service soon.

But wasn't this already posted some time ago by @LKJ86 ?

Why does the Y-20 not have the WS-20 yet? Strange since a couple years ago I heard the WS-20 had the smoothest development out of any Taihang engine. Until they get the WS-20, the Y-20 cannot realize its ultimate potential.

Y-20 has already realise its potential.. The current engine fitted is not the ordinary D30KP2 engine but Chinese WS-18 clone but upgraded engine with more superior fan blade and higher thrust. The current Y-20 configuration is capable of hauling PLA most heavier MBT of Type99A. Higher payload is not necessary at the moment.

The reason for Y-20 to retain WS-18 are simply logistic point of view and cheaper maintenance since WS-18 engine share the same place of IL-76, H-6K and Y-20.

WS-20 will only introduced once military C919 convert to AWACS , MPA or AEW since the engine for it cannot be imported from US.

then why did China import so many D30KP2, for H6? Surely not

Are you sure China imported many DK30KP2? Where is your proof of many(300 above)?

From what I know China only imported 120 DK30KP2 in the 2012 and no more subsequently. We have almost a hundred new H-6K, H-6N in service plus almost a dozen of Y-20 and not to mention many KJ-2000 and IL-76 in service. A simple maths calculation show it need at least 300-400 engines for now and future.

Photo show the successfully testing of WS-18 engine in the late 2015 and since WS-18 is a clone of DK30KP2 but with more superior metallurgy. It shouldnt take too long for it to cert and enter production service. Notice in 2017- until now, production of Y-20 , H-6K and H-6N have increase significantly, more or less how the engines supply is not a bottleneck as production ramp up to meet the demand.

The Y-20 needs high bypass turbofan like WS-20

Not in expense of cost and maintenance. WS-18 still consume less fuel compare to turbojet and higher thrust to fulfill current PLAAF needs.

WS-20 maybe install on enlarges version of Y-20 civilian to haul bigger/heavy cargo.

But that might be 5-7 years later date before you see WS-20 install on it.

Latest satellite photo shows 17 dark painted Y20s at the factory.

Happy New Year 2020!
