Y-20 heavy transport aircraft News & Discussions

[Figaro]

Deino, do you know what these few highlighted few sentences say?

New engine core technology is used on the engine of Y-20 which spec excel even US aviation standard. If the engine of Y-20 is imported purely Russian DK-30kp2. Why even need to input of Chinese technology of engine core?

Another clear evidence engine of Y-20 is not as some expected of Russian imported. But as what I always claim WS-18 domestic engine. Outer look of engine is deceptive. It is the inner that counts.

Ask you good Chinese friend to translate for you. and this new is from official Chinese website indicating national award for scientific achievement. Not some rumors or fake news.

Y-20 has long achieved 100% domestic made. Not even engine is imported.

It doesn’t matter if the Y-20 currently has Chinese engines or Russian ones. We all know that the WS-18/D30 is a low bypass engine that is unsuitable for the Y-20’s needs. The real creme de la creme is the high bypass WS-20, which is going to be incorporated on the Y-20 this year. Afterwards, the WS-18 will be of little use ...

WS-18 can be used in H-6K.

Hi, WS-18 is not an exact copy of D30kp2. Its engine core and fan blade are definitely upgraded and performance is far superior than original Russian one. H-6K is reported to have far superior range, payload and cruising speed. I doubt by just swapping out with basic d30kp2 , such drastic change of performance can be ahieved.

It is important not to reply on foreign import. The number of Y-20 build will not be restricted and even export is possible. By the way, current Ws-18 satisfy the need of PLAAF strategic needs. PLA and marine do not have 60tons heavy tank like western and there fore current spec is more than adequate to handle 90% of China military transportation.

WS-20 is more important for the militarize of C919 as AWACS and MPA therefore China do not need US Leap engine for such task since they are not allowed to be link to military projects. SFA-100 engine will only be available in 2025. That is too late. As-20 will be used.

Old H-6s were fitted with Chinese WP-8 jet engines. D-30 turbofan engines are used on H-6Ks, hence the performance boost.

Aerial refueling variant possibly?

The WS-20 is slated to be placed on the Y-20 in the latter half of this year ...

J-20 uses a probe + drogue, not boom-type refueling.

Y-20 currently uses WS-18 domestic engine which looks like Russian D30KP2 but has more power output and longer lifespan. It can fulfill PLAAF needs.

Sorry to nit-pick ... there is so for proof for this even more to the contrary other reports I know say, that the WS-18 was indeed initiated as a fall-back option in case the WS-20 fails or encounters technical issues, but since it is fine it has been downgraded to a technical project only with no further serial production at least not for the Y-20.

I think at this point, the WS-18's primary target is the H-6K or future variants, not the Y-20. A modernized low bypass engine would suit the H-6 quite well.
