Y-20 heavy transport aircraft News & Discussions

[White and Green with M/S]

Su-57 also made maiden flight earlier than J-20, and then?

So what's your point

The WS-15 has already conducted flight testing aboard a modified J-11 (not the J-20). This was confirmed at the beginning of last year IIRC. Considering the WS-15 only completed high/altitude core testing in 2009/2010, the time table is not slow at all. Also, you have to take into account the numerous revisions the Chinese have taken to modify the WS-15 ... the current iteration is much more advanced than the one envisioned in 2006 due to incorporating new gas turbine technologies. This will also produce delays.

Where can you have any pics on that ws-15 are currently testing on J-11 , i would like to say that's only just a rumors we are hearing about from years

The reason why the WS-10 was built on a CFM-56 core was because the MIC at the time (late 80s) did not have much funding and the limitations of China's military technologies. But a lot has changed since then ... the Chinese thrust to weight ratio 10 core demonstrator was tested successfully at the turn of the century (CJ-2000), which later became the basis for the WS-15. Experience is another thing that is very overrated ... it can be argued the Chinese had little experience compared to the US, Europe, or Russia in practically all areas of military hardware. Yet why have they been able to catch up and exceed in some aspects so quickly? The person playing catch up usually has a much easier and faster time than the person who is already at the

I am talking about REAL FACTS, you might be good in electronics and mechanical aspect of your military hardware but engine development is one of the most difficult aspects of military hardware development

So what's your point

And again, what did you mean?

Yes

Wow ... at Xi'an or any of the operational bases?

So, seems like the picture of the Y-20 is someone who widened the D-30 engines to make it seem like WS-20s (original pic 2, doctored pic 3).

BUT all the big names confirm the real Y-20B with WS-20 has flown, and notably is in yellow primer. (Speculative art pic 1)

Already snow?

That northern region of China even has a cool summer... to my surprise when I visited the northern part of Shanxi 山西 -- just adjacent to Shaanxi 陕西 with its capital city, Xi’an -- during summer a couple of years ago, the climate was very pleasant (as I don't like hot weather, thus have a good memory). Therefore I have a little wonder that winter is coming earlier to that part of China, incl. the NE region, all thank to the Siberian winds

Not really! Why not one grasps it that the factual picture is not yet the right time to circulate (unless one wanna get a tea invite, which ofc nobody wants it) but the actual test was already done. The pic is just a symbolic representation, but every long time watcher know that the pic ain't everything wrt PLA development (for we have seen a lot about these pic things in the past practices)... regardless whatever outsiders may wish to demand! Just be patient. For the rest, believe as they wish...

Where can you have any pics on that ws-15 are currently testing on J-11 , i would like to say that's only just a rumors we are hearing about from years

You have been here long enough to know that Chinese military developments reports are first based on rumors/leaks and that pictures only follow thereafter. For something as sensitive as the WS-15, I doubt we will be getting any pics so I wouldn't hold my breath. However the WS-15 flight test came from a very reputable source. I'm not so sure why this development is so surprising for you given the engine's timeline.

I am talking about REAL FACTS, you might be good in electronics and mechanical aspect of your military hardware but engine development is one of the most difficult aspects of military hardware development

And the "real facts" here are that virtually all Chinese major aircraft variants are using a derivative of the WS-10 or another Chinese engine. You can say Chinese engine makers have no experience compared to Western or Russian makers but the fact is all new aircraft are being produced with Chinese engines.

For those who do not realize the significance of this image, those are 4 WS-20 engines on the Y-20.
