This all certainly makes sense.

It reminds me from the talk a few years back, the talk about the "WS-10IPE" was that it would apply some technologies that were in development for WS-15, the most notable of which at the time was the application of monocrystalline blades which the original WS-10 didn't have and which the original vision of the WS-15 would have been the first to implement.

Given how capable the WS-10C on J-20 appears to be (as well as the ?as of yet unknown new WS-10 variant seen on production J-16/Ds with the new nozzle over the last couple of years), I wouldn't be surprised if they have seen the first benefits of WS-15 R&D applied to some of their subcomponents.

Assuming that "monocrystalline blades" is the same as "Single Crystal Blade" .... actually I am a bit surprised that original WS-10 didn't use single crystal blade. I thought China had mastered it long time ago

Not when the WS-10 first came out. They had single crystal blades in R&D when the WS-10 first came out but they didn’t go into mass production until around the mid 2010s. The WS-10 itself was first developed with directionally solidified blades and had to be revised with single crystal blades.

Thanks. Assuming now single crystal blade is widely used for Chinese engine, so China only adopted single crystal blade for ~10 years

How about Russia? .. I think AL-31 didn't have single crystal blade

Every military jet has different exhaust colors at different power settings due to different fuel/air mixture ratios.

I have never seen such hue on J16. In fact, this question was asked by the military photographer himself.

I think AL-31 uses directional solidified blades.
It kind of make sense of the engine life of the older WS-10 if it uses DS blades too. Squeeze the performance and suffer the shorter creep life.
So if they now have SX casting mastered, I am wondering if that they kept developing the metallurgy with Rhenium etc and cooling & TBC/ceramic coating technology in parallel, and were able to apply in on the new versions were the reason for the re-speccing of WS-15.
Each one of them may not be much, but you lump them together against DS blades, that is some massive gain in performance and life.

The next step is to use niobium.
