China has NEVER been able to build a reliable jet engine...military or commercial.
Their best aircraft are equipped with Russian engines.
And Russia has supplied them plans...even engineers and they cannot produce a reliable replica.
Most analysis of the issue from the outside suggests Quality Control lapses at all phases of construction. They just cannot seem to apply proper rigor along every stage.
From Materials Science, to Machining, to Assembly. These very, very smart people have a culture of shortcuts.
I definitely would not want to go to sea on a Chinese submarine. Or fly in a jet with Chinese engines.

Check eBay for the nickel superalloy, too much work to make at home.
I think they’re referring to the compressor vanes.
Not sure that the Russian engines are ‘all-that’ either. Russian planes of previous generations never flew all that much.
The Russian design philosophy seemed to be “these things don’t last long in combat, so build a crap-load of them . Fly them just enough to gain minimal pilot proficiency, and leave them parked the rest of the time.”
That being the case, why build a jet engine that is durable when you can build one that will last a few tens of hours before replacement? That is who the Chinese are copying designs from.
They were not able to steal engine blueprints from us and others
sounds right to me
“The Russian design philosophy seemed to be “these things don’t last long in combat, so build a crap-load of them . “
But there is a certain logic to that.
The next “big war” will last hours to days, not years. Unlike previous wars, it will be run with what you brung. The Russian airplanes are lighter weight and probably a bit “flimsier” for performance with somewhat inferior components and engines. On paper, some Soviet aircraft met or exceed our equivalents in the 70’s and 80’s.
Their planes, unlike ours, are designed to operate in much colder temperatures and land on “semi-improved” runways, so they lose some performance in the undercarriage weight.
Stalin said, “quantity has a quality of its own”. You might rather have five pretty good weapons that two excellent weapons. Look at the brilliant designers we have who designed a ship and its gun with an $800,000 “shell”. It might have incredible accuracy, but a case can be made for 50 “pretty good” dumb shells and two smart marksmen.
Bonus: If you sell Russian weapons, you can expect a steady stream of parts business almost immediately. If your “friends” suddenly experience “regime change”, the Russians can cut them off, and weapons systems become worthless in a few years. Ask the Egyptians and Iraqis about that. Then, ask the Iranians how much they appreciated US military equipment quality in the post-Shah era. The Vietnamese had and have a lot of respect for the quality of our weapons and technology, also.
“Perhaps they can steal the technology needed from GE or Pratt and Whitney”
A bit harder now. With a Democrat in power, just call the the right staffer, offer some campaign money in exchange for know-how, and you’ve saved many billions of dollars and years of research.
Now they have to call their trench workers. The ones who get hired by Pratt and GE because Leftists make damn sure that Americans (in general) are NOT educated to do the engineering work that these companies need. So just a call or two from the ‘motherland’, a reminder about the Chinese New Year starting this week, and all their problems are fixed!
I can’t argue anything you say. Even the vaunted T-34 tank from WW2 was crudely built because it was only expected to last for 1 or 2 engagements. But it worked, and scared the crap out of the Germans in their Mark IV panzers.
“ Even the vaunted T-34 tank from WW2 was crudely built because it was only expected to last for 1 or 2 engagements. “
I’ve read that many Russian tank crews were injured in them - by casting flash!
They’re 5th generation Fighter is more about nationalist propaganda than competing with the Americans. We are about 50 years ahead of them in aircraft development.
How long do you think it will take them to develop a nuclear powered flying triangle with gravity disstortion and cloaking technology that can operate at Mach 7 to Mach 9.... in atmosphere or out of atmosphere?

After 10 to 12 years of the following the internet reports about the TR3-B Astra.... and seeing about 100 videos of the craft in operation, I’m absolutely convinced it is real.
Two TR3-B Astra in flight. This aircraft is beyond revolutionary and has scared the crap out of our enemies.
And remind me not to use spell-check anymore. I do know the difference between “they’re” and “their”.
