can someone with better Chinese skills than me read the first post here and explain what this guy is saying about IL-76?
Assuming they have the blueprints and a large turbofan will be ready in the near future, how long will it take to replicate and start manufacturing of the aircraft?
He said, apparently some people from the Kazakstan IL-76 factory was willing to sell the full blueprint and technical documents of IL-76 to China a few years ago. That was after Putin cut off supply of parts and services to that factory. China didn't respond right away because there were internal debate of whether to take the offer and produce a copy of IL-76, or start fresh on a new design. The follow on postings lamented that there are too many "traitors" holding China back.
Frankly, I don't think these people understand the basic concept of "Intellectual property". Even if China received everything on IL-76, they still can't produce it unless authorized by Russia as long as China still wants to maintain friendly relationship with Russia.
A year or so to source or build all the machinery, find a factory, establish links with potential suppliers and start connecting the supply chain. If the Chinese want modifications to the design, such as engine upgrades, avionics upgrades, etc, then tack on another year or two.
Only in your dream. A set of blueprint only tells you what each part's physical dimensions and what material it is, it tells you nothing about how to make them. Those would be mostly located at the part's manufacturer. To figure everything out would take years if not decades. There are plenty of examples of such reverse engineering operations in China, such Y-7, Y-8 and J-7. China had blueprints on all of them before 1961, and only mastered the manufacturing technique nearly 20 years after the fact.
Actually, they have quite a lot figured out with IL-76 already, they've been operating it for a while. They've studied enough of it to be able to convert it for use for KJ-2000 + engine testbed. They've licensed to service it. They even have the engines for it. And the machines they have and aerospace technology they have is easily more advanced than what IL-76 carries. So, you can't compare it to those examples. In fact, it only takes them 15 years to develop a brand new fighter now. So, why would it take them 20 years to copy something like IL-76. Think about it.
