What are they Japanese using their technology for?
Someone can translate ?
Its an academic journal on manufacturing process of high thrust mid bypass ratio geared turbofans. From what i could gather from this excerpt, this journal discusses the importance of tooling and human management in the manufacturing of planetary gears. (it says special grade steel, very thin wall so i'm assuming ring gear, as i dont understand Chinese technical jargons that well).
So nothing to do with a low bypass turbofan jet engine like the NK-32...
Mid bypass it says, high thrust and I forgot to mention afterburning. Interesting.
Geared turbofan with afterburner ?
I have seen this article before. It is from the 1990 to 2000 timeperiod . Quite old article ( apparent from the Font) and conveys very little regarding today's activities or progress. Studies on GTF has been going on for some time to keep pace with the activities of US/UK in this field as far back as 1990s.
The articles that mention China is only working on R&D phase of GTF is from 2014 to 2018 timeframe ( the images I posted are from those articles). I clearly mentioned that was AECC Civilian Turbofan division and not military.

The Japanese have developed fourth, fifth gen SCBs. But I am going to presume its technology accumulation for their F3 fighter jet program where they are going to collaborate with Rolls Royce and UK for both Aircraft and Engines. Not that Rolls Royce would desperately need IHI/ Japan expertise ( they don't. Most know that).
ask the Japanese.
