Re: Why jet engines aren't made in China
#22This is a strange article. I did not find anything that is a blocker for China. China is a relative new comer to jet engines and this technology is tightly guarded by incumbents and needs time to mature. If China can master nuclear, space, chips, it seems a bit stretch to say they it is the Jer engines where they fail.
I even thought that the example of automobiles proved the jet engine analogy wrong. Sure, automobiles aren’t as complex as a jet engine, but they’re still complex, especially the internal combustion variants. Something like 10 years ago we were laughing at videos of Chinese cars spectacularly failing crash tests, and now China is selling to very heavily regulated markets. Same deal with things like high speed rail.
High speed rail technology is not a secret. We in the US just don’t have the will. Auto technology in China was acquired via tech transfers. In order to open mfg in China foreign concerns were forced into partnerships with local companies; moreover there was an effort to obtain foreign trade secrets. Metallurgy for jet fans isn’t one of the technologies the west has tried to partner with China. At this time the UK, the US and Russia hold the lead in that technology -maybe France has some too.

Material sciences needed for modern jet engine blades are a closely guarded secret, and thanks to not manufacturing them in china, those secrets have managed to remain not stolen. Fun story: it is not just jet engines - it is only recently that china was able to actually make indigenous ballpoint pens https://www.bbc.com/news/business-38566114

Material engineering is the well known blocker for China, same with semiconductors. They basically have to replicate 50 years of trial and error that is well kept under lock in key in the west.
China hasn’t mastered chips either yet in the same way it hasn’t mastered jet turbines: they can do cheap (high yields, low maintenance costs per hour of use), they can do high performance, they can’t do both yet at the same time.

#25A lot of claims in the article.
IDK if the WS-15 failed or is "two decades" behind. I think we just don't know, but we do know that it is that they have achieved the ability to deliver, in mass, third-generation single-crystal nickel-based superalloys. That's a strong proof point.
As for commercial, China can/has grant a sizable portion of the C919 to domestic engine producers ( I think AECC has this contract ) that allows for a lot of capital and practice.
I would not be shocked if China demonstrates highly competitive engines in the late 2020, maybe with a few setbacks and iterations. I would also not be shocked if they started demonstrating engines with some characteristics slightly better than the Western manufactures in that time period (or maybe a little later).

#27I work in the aviation industry. This was a good read. The article hinted at the oligopolies that exist in aviation and in practice the industry is incredibly conservative and slow to change (particularly commercial aviation). While new technology is developed all the time, the extreme regulatory oversight combined with so much of the industry relying on long-standing relationships makes it difficult for any new entrant to come into the market. There is also a lot of domain specific knowledge that seems difficult to easily transfer.

You fell for a meme that was tired years ago already (your link is from 2017, after all). The article itself notes, “Relatively low-value items, like ballpoint pens, have not been a priority”, so obviously this says little about higher-priority military and industrial areas to which the CCP devotes greater effort.

Is aviation encumbered with patents like software development is?

Can Chinese companies order just the blades from RR or P&W? I've watched their manufacturing video recently and shocked how much of it was hand labour - it's not something I'd associate with precision. My partner said they must know better tho lol.
The RR video showing manual assembly of wax molds is a low volume development line. It isn't their main production process.
I've seen that video. Guaranteed they wouldn't have put the slightest bit of information in there if they thought would help the competition.
