China's transport, tanker & heavy lift aircraft

You're talking about WS-20, which is still under testing. I expect it's going to still take a couple of years.

The equivalent Y-20 numbers are just for illustrative purpose. PLA actually has a lot of needs for D-30KP2, for its IL76/78 fleet, H-6K fleet, as well as Y-20.
If it's anything like the WS-10, then the Second Coming could happen first.

I really hope your are not serious, because every time you make a comment about anything related to Chinese engines in any thread, you inevitably bring up WS-10 as if it is some sort of failure.

Then everyone responds to you saying that WS-10 is in mass service among the many SAC produced flankers and that is evidence of quite a substantive amount of success, and then things just end up getting snarky when you seem to refuse to see that as evidence of anything and still maintain that WS-10 is some sort of failure and everyone else becomes frustrated and then we end up with two or three pages of off topic posts, possibly with a few political remarks thrown about as well. (before the discussion burns its own oxygen away or until a mod intervenes)


It's happened so many times now it isn't even funny.

For the sake of this thread and not causing it to drift off topic especially now in Zhuhai airshow season when everyone is interested on keeping up to date with new pictures, I will ask if you could give it a rest in this thread?
Because I'm tired of it and I think most others are tired of these sorts of discussions too popping up unwanted in threads about a given topic, and if you really want to exhibit your skepticism towards WS-10 and general Chinese engine efforts you can create a dedicated thread for it to keep it from diverting other threads and triggering everyone to bombard your off-hand snarky comments with pages and pages of replies. So I'm trying to pre-empt this thread from going off the rails, which it likely would without an intervention.

So, PLAAF giving up on WS-whatever.

Eh? What does the purchase of D-30PK have to do with the WS-20? That still has a few years of testing assuming things go perfectly according to plan. In the meantime,

1st Generation Y-20 each require 4x D-30PK-2, excluding spares
All H-6K requires 2x D-30PK-2 each excluding spares

Once you include spares for new planes as well as existing Il-76/Il-78/KJ-2000 that would total a lot of engines. There is no surprise with this purchase, and you can expect even more engine purchases in the future be it for new planes or existing ones.

Interesting. So Russia/Saturn and China have signed two contracts to supply 224 D-30KP2 between Q1-2017 and Q4-2020. The first contract is for 54 engines, the second for 170 engines. Here is the delivery schedule by quarter, their total deliveries by year and yearly equivalent # of Y-20, assuming all engines will be used for Y-20.

If XAC indeed follows this production schedule, it would correspond to 1 Y-20 per month, roughly.

The news also mentions that two contracts signed in 2009 and 2011, for 55 and 184 D-30KP2 respectively, were delivered by 2015.
They need engines for H-6K and replacements for Il-76/78. They also need spare engines for the Y-20 so each aircraft will need a bit more than 4. A more realistic number might be 30-40 Y-20. But on the other hand if we also count possible WS-18 and/or WS-20 to be fitted on some aircraft before 2020, then the total number might be more.
