The IL-76LL aerial engine testing machine equipped with WS-20 engine. The development of WS-20 engine is nearly completed, it seems that we will start the on-board test to Y-20 nearby.

an news about ws 10

Looks like there are two type of AVEN design, one is testing on J-10, another was operated by Chairman Jiang.

The first type of AVEN, which is testing on J-10:

From a Journal

The second type of AVEN, which was patented by AVIC Shengyang Liming Aero-engine Group.

So the MATV type is the one currently being tested on the J-10?

Maybe both of them.

Look at the military attire, if it's during Uncle Jiang's time, it meant they had a functioning prototype 15 years ago.

 

[Han Patriot]

It's probably just a demonstrator than an actual prototype ... it wouldn't take 15 years for China to implement TVC

Actually, it would take that long since the domestic engine was not mature enough to mount such a mechanism.

I don't doubt it but I find it highly unlikely that the Chinese had a working prototype during Jiang Zemin's era ... to have a working TVC before the completion of WS-10 in the mid 2000s is unlikely. Maybe 5 years ago but 15 sounds too far of a stretch ... and it makes sense given the state of the Chinese engine industry then and now.

CJ-1000A will win out over SF-A and keep ACAE as a viable and independent organization as opposed to being pulled into the larger, military oriented AECC. The competition is good for China.

Either project is historic.

What's the status of the SF-A? ... and it is developed by whom?

What's the status of the SF-A? ... and it is developed by whom?

SF-A is believed to be a civilian version of WS-20, which matches the older generation of CFM56. SF-B refers to CJ-1000 series which would sort of match LEAP although the specification will still be lower.

SF-A was heard being rejected by the end user, ie. COMAC.

Although CJ-1000 will have lower specification when it enters market, Chinese government is rumored to guarantee its 30% to 50% installation percentage to the C919 planes. The other 50% to 70% will be filled by LEAP.
