W15 runs into problem.

Overall, the engine issue not solved.

If we could tag users on SDF, I'd probably tag you as "harbinger of bad engine news" given your proclivity and doom and gloom view of the chinese engine industry lol.

Go figure, like us they depend on a bunch of online leaks. If we're going to believe everything this segment says, we'd have to believe the J-20 could go into production next year!

EDIT：Never mind, spoke too soon. Similar but not the same --;.

On the other hand, China's problems with WS-10 make it believable they have problems with other models too.

Of course.

But "the engine problem is not solved" is a ridiculously vague and seemingly vast overarching statement, so it's almost worth no recognition at all.

Definitely. I found the comments about China's potential trouble with high rpm shafts to be particularly interesting but also hard to couple together with reality. There's a chance that it's right, but we've never heard this particular piece of the engine being a problem before, even for the WS-10, and one would think something like that would prevent the WS-15's core from even going into testing.

EDIT: Found the whole slew of videos. This analyst is VERY conservative about his assessment with the J-20, to say the least.

According to the article China faces problem of producing high-end ball bearing for jet engine.

Even though people are saying WS10A issue is solved and mass produced for J11B, I still feel something is not right fundamentally. How come so many other new aircrafts are avoiding WS10A. I don't know what that is.

Maybe that explains, I don't know. Maybe China is capable of producing medium-end ball bearing but not the high-end one therefore WS10A is not as reliable and durable as it should be.

Because J-11B production is ending, and WS-10A either has corrosion issues for J-15 or PLANAF are just being conservative. For J-10B, possibly the new Al-31 variant it's using is simply better than WS-10A.

But there is nothing strange, because J-16 is using WS-10A and when it enters production you should see it on new planes again.

Or maybe it is none of the above and shenyang liming simply can't make enough of them.


Fact is, WS-10A is already in mass service meaning whatever problems it had must have been resolved to the PLAAFs content. This, it means the reason it isn't equipping J-10B and J-15 must be something else not related to the engines performance or mass production reliability.
