Hard to deny it's in mass production now.

No offense intended, but I think you are interpreting what you want to believe. Notice in the sentence that follows, it is talks about incremental success and incremental progress. I don't think mass production starts without 100% success (success from their perspective).

本报讯六○六所自9月13日开展国防建设重点工程责任落实及大干100天活动动员大会以来，全所上下掀起了如火如荼的大干热潮。国庆、中秋长假期间，该所30个基层单位的职工始终战斗在生产一线，“太行”、“昆仑”有关型号，新型发动机，预研项目等生产线全线发力。在奋战之下，某燃机耐久性考核试验实现阶段性成功，某重点型号发动机取得阶段性进展，这些都是为新中国60华诞献上的厚礼。

Hey Maya, do you know what the new engine is, since WS-15 and the large bypass engine has gone to XAEC? And what's the gas turbine mentioned in there? QC-70, QC-185?

my conjecture :FWS-15 and QC-185.
QC70 received the technical certification last year:

No.606 is SAERI--Shenyang AeroEngine Research Institute,the chief design institute for the FWS15 full-scale-development program. XAEC conducted trial-manufacturing of the CJ2000 demonstration core engines.

We've been wondering here. Are the problems with Taihang more due to the original design or due to Liming's production/assembly process?

Manufacturers including sub-suppliers are mainly responsible for the engine's reliability problems , while 606 Institute is responsible for some operability problems.

How can such important national project subcontract out for parts?

Yes, it maybe cheaper but success/significant of WS-10a far outweight profit.

By sub contracting out, u will have a hard time for quality control of your final product.

Politics may be there.

Might be an attempt to prop up failing SOEs, or even an attempt to improve the quality of manufacturing as a whole by distributing higher standard requirements.

It's not necessarily a bad thing. At the end of all this it may not only help improve the quality of subsidiaries (giving them valuable experience for further development), but may help teach China exactly how to enforce standards and regulations.

What are you talking about, ever heard of F-136? They actually subcontract to another country. Same with F-135 and I'm pretty sure if you do some research, you can find this to be true about most engines out there.

interesting. so SAERI seems to be the chief designer for all the major engine projects in China?
