this is pretty much what i said... chinese aviation sector has the inherent weaknesses of being state managed, only recently semi-privatized. private firms in the west have built up intellectual capital and experience from being on market for decades... also china most certainly lags behind in materials science compared to the west, maybe they can achieve an improvement over the imported russian turbofans but they are certainly behind the cutting edge. -i would also like to bring up another likely obstacle to chinese efforts to built modern engines among other things: software.
now about your argument: first you claimed that china does not have quality control issues when it comes to engine parts, but then you refute yourself and talk about an immature supplier chain that can be unreliable in the quality of their products, please make your point more concise. furthermore i think your argument could be made better with less tech trivia and jargon that isn't immediately relevant. simply too much stuff to look through!
It is not so simple as to blame the reliability to quality control. You have to understand how High tech machinery is built.GE, Rolls Royce and Snecma or AVIC are what they called system integrator. meaning they don't manufacture all the components themselves .Some critical components they do built it themselves.Then they assembled the components and added the software,control and electrical system.
China follow this model since the the economic reform in late 80's.AVIC or their predecessor stop being the vertical integral company long time ago So they have to depend for some of their component to the supplier. They probably help set up this component supplier or even spin it out from the own factory
But they have to live on their own device after the split. In US and Europe this people have grant to do research and development. They were underwrite by the military when the military budget were fat. Then they applied what they learn in military sector to commercial aviation or industrial sector to generate income .Which allow them to further their own R&D and win military contract. So it goes back and forth. In other word they become the best in their chosen field or component thru further research
So it is structural problem and not as simple as quality control. But in China the civilian aviation is just started because for a long time China were poor country No one fly in the air . It is not too long ago that the prevalent mode of transportation is bicycle let alone traveling by air.
So what I am saying the system integrator like AVIC has no problem with quality control since they were supplier to the like of GE and Snecma and has to meet the strict requirement of those company.
But the smaller company or component supplier is not so lucky they don't have the budget or grant like AVIC. They have to live on their own device. But now that China civilian aviation start kicking and they are designated as pillar industry and the promise of opening the military sector to civilian I expect better component supplier in the future.
china is not short of talent or capital
I don't bring those terminology for nothing. In order to evaluate the mode of failure you have to know those terminology and cause of turbine failure.If material is the cause it will be catastrophic as the article show it .But we have no report of catastrophic failure so far
Software is the least of Chinese problem there are tremendous software industry in China growing by 30% a year and the best use of software is in Telecommunication industry and Huawei already eclipse Ericson as the largest Communication infrastructure provider. The proof in the pudding is they are as good as their counter part in the west when it come to hacking and cyberwarfare
