Summary or translation pls?
Nothing particularly interesting at this point, the table just lists out who each engine uses their alloy product.
Honestly, I am not an industrial expert, don't even know what they means but here you go.
| Engine | Their product |
| WS-10 series | Deformed high temperature alloy rods, GH4169 disc-shaped piece, Ring Parts, Fastener, Sheet metal parts,etc |
| WS-15 | Deformed high temperature alloy discs, Ring Parts, Fastener, Sheet metal parts,etc |
| WS-19 | Deformed alloy GH4169D high-pressure compressor integral leaf disc, Shaft neck part, Baffle, Turbine Disc |
| WS-20 | The same as WS-10 |
| CJ-1000 | The same as WS-10 |
| The 5th Gen engine | Deformed high temperature alloy rods, Ring Parts, Fastener, Sheet metal parts,etc |
Calls engine WS-15 during audio but keeps it XX-15 on the power point slides. Who do they think they are fooling?
Design certification=cleared for production. Production certification=no longer needs continuous improvement in production process or design, aka the product is mature and the production process is locked. You could put quite a lot of product out in the real world before you get production certification.
In other words if the interview answer is true the WS-15 is probably in small batch production. They’ll want to proceed with small batch production to enter the product introduction phase where the goal is to both get product out into real use (probably through integration testing and early employment with pre-production and early production J-20B) and to work out any remaining kinks with design and production process, especially any problems big or small they see while scaling production or while the first products made through a mass production process gets tested in real use conditions.
This is a huge milestone. If true it shouldn’t be long before we see J-20 flying with these engines. It would be really nice to get more information on the WS-15’s performance capabilities and design details but that may be a longer wait (sadly for me).
How much of these engines are actually made using machine tools native to China? Interestingly enough a Western think tank released a report five days ago with the following finding:
The biggest deal to me is just seeing that they've frozen on the design and material already. That tells me the initial testing has been quite successful. This is a huge milestone. When WS-10 was first put into service, it really was rushed. As they started production after design certification, they were still including and updating the materials they were using. Because the original material they used in the design certification just simply wasn't meeting standards once they put it into use.
What we can see is that WS-10C already matches PLA expectations in performance and service life. So WS-15 likely will be already be relatively reliable by the time it is put into service with J-20.
And when it comes to next gen, it appears they are already far along in development. that's great to see. and by the time it goes into production, I would also expect it to be ready from design & material science point of view. That's something US/UK always had when they developed new engine and China never had until now.

We don't need a stupid think tank to tell us where they are at. We have a fellow member @abenomics12345 who actually meets with Chinese CNC makers and ask them questions about their technical level and how much of their parts are domestic. In 5 years, Companies like Kede will be first rate in all of these areas. Seriously, stop posting nonsense from CSIS.
