suppose we got the blueprints and entire process to make blisks , we are not in a position immediately to manufacture 1000s of reliable aero blisks. and even if you do, you might not have the insights and data banks to resolve problems easily....the continuing problems with the WS10 is a sign of that. and without fixing it properly first, due to timelines they are forced to start on the WS16 or whatever is supposed to power the j20 eventually.
Yes we can! If there is a credible threat to be dealt with, we ask the best in the world for consultancy in both design and manufacturing, as is happening with Indian aero-engine programs (both the large and small ones). We agree to pay good money for that and is as transparent as it gets. We had design bureaus getting constant training and entire plants setup by such consultants for cutting-edge offensive weapon areas (from cargo shells to ATV) in which we had issues in the past. In fact all these program issues (conceptual and manufacturing) will be published threadbare in Indian/world media, open tenders called, decisions made in double-time (whomever be the current govt) etc. Some of the conditions for such consultancy include getting operational data from their own forces that operate the equipment, as well as being there to trouble shoot during hot-times.
Plus as NRao-saar has been trying to point out, even if you have a thousand blisks/day capacity, you need a giant system, that assembles it during wartime and maintains these thousands on the frontier. But war too has evolved. As Prez Obama derisively put down Romney in a debate about "We have lesser number of horses and muskets too", things are different since WWII era khanland assembly lines. With modern day shorter duration air-ground campaigns, it is more about inventory/stockpile management, than production lines etc. Khan is boss because of all these pieces that come together in a magical (money) fashion.
But China has none of the above consultancy advantages in military systems areas, due to their "adopt without asking" system and even among the chinese policy makers, some of them don't seem to like this isolation. Hence the constant pressure by one CPC faction (realists) on EU to lift embargo, so they can toss away the crap produced by the dick-head faction (people who convince the jock faction that stealing is better for budgets) for parades and shows.
Contrary to belief of many, copying is actually a legal and well practiced competitive method used by all manufacturer and designers.
Copying in a legal way can be done by license production. eg: Ford was licensing Toyota's hybrid drive-train, till they got their act together.
But here a government news agency getting pissed over Russians saying "WTF?" about a design seems to be the point that we diverge from the chinese.
