Also old news we got as early as 2008-9
. Notice the lack of concern about the WS-15's progress by veteran members, even without any leaks about progress or developments.Engineer's last post actually summed up what we've gotten the last 4 or 5 years in terms of timelines really well. The only other thing to really add is that the ws-15's core supposedly entered high altitude testing around 2010-2011. Beyond that there's still an uncertainty about whether the ws-15 will be in the 150-160 kN range or the 180 kN range, and whether it will have tvc. Those are the sorts of things we'll only know once it's actually completed development though.

That is not defined in the diagrams. By context, the words above 2014 says "trial and testing", above 2015 it says something along the line of "creation of logistic system", and above 2016 it says "review reliability".

Ohhh ..... how I hate these step-ba-step unveilings, it's just like aircraft-porn !
Even more since the one who made this image surely has a complete image ... so come on !!
Anyway it fits nicle to the so far only "said to be WS-20-image" we have.

PS or the real deal?
Looks pretty real.

The issue here isn't about rights to express opinion. Certain individual got his chance to claim Chinese were shopping for Russian engines already, so he already exercised his rights of expression. This issue is this individual cannot accept opinions contrary to his. Worse, this individual has often shown to lack support for his claims, and sometime shown to contradict facts altogether. What this individual shows is an insistent of preaching religiously, which has led him to be banned from multiple forums already.
I for one, am glad that his ass is gone from our forums as well.
Anyway, here are some diagrams I have meant to post for some time. The first is a general time line of various aero-engines in China. From bottom to top, the rows can loosely be interpreted as near-term goals, medium-term goals, and long-term goals. If WS** corresponds to WS-15, then testing should start by 2014. Reliability testing should start from 2016.
The second diagram is similar to the first, except things are arranged into columns now. From left to right are near-term goals, medium-term goals, and long-term goals. Again, these are loose interpretation. Here, we actually see WS-15 in the category of near-term goals.
The third diagram has explanation of near-term, medium-term, and long-term goals. We also see that China is undertaking 22 jet engine projects simultaneously, while the US has 30 jet engine projects. Of the Chinese projects, 14 of them are in [engineering] development, 4 are core engines undergoing development, and the remaining 4 are in preliminary research phase.
Finally, see see a time line of a typical aero-engine project. From concept to deployment, it typically takes 30 years to complete. So before people use the lack of news on WS-15 to argue that WS-15 project is in trouble, they need to realize things must take their natural course even when everything is working according to plans.

How could WS-10x AND WS-9x be medium term goals, and WS-15 and WS-20 be near term goals?
Unless the Chinese character "x" stands for improvement.

If you are referring to the second pictures, the "改" stands for modification or improvement.
