Chinese Engine Development

Me: "This brings back memories of me a few years ago trying to pin down exactly what defines a propfan, and then just giving up. .... Perhaps one definite statement one can make about the distinction between turboprops and propfans is this: So far, for all engines called 'turboprops,' the axis of rotation of the propeller is offset from the axis of rotation of the compressors/turbines of the gas generator, while for all engines called 'propfans,' the axis of rotation of the propeller/fan is the same as the axis of rotation of the compressors/turbines."

Tomboy: "Not really true as from the top of my head, NK-12 and AI-20/WJ-6 has a coaxial propeller"

Now you can see why I previously gave up!

We should all pat each other on the back for making an effort and go home (separately no homo) on this one.

ACAE is said to be currently developing a propofan engine. Posted by SOYO on Weibo.

That 3D-printed turbojet test reported by CCTV last November, now just being reported in newspapers.

Wow!

China's "Heart" Reaches New Heights: CJ2000

That is indeed a new PR!

We're at the cusp of a new era in aviation. The final barrier has cleared.

It is now just a matter of time before the China Wave hits planes like it did for ships, drones and cars.

I has dumb question: If you can M2 without AB, why have AB at all?

More thrust = better climb, acceleration, and higher sustained maximum G for a given flight regime.

CJ-2000's progress seem to be faster than CJ-1000A, I guess the breakthrough of CJ-1000A helped expediction of CJ-2000's development work.

It will be a pleasure to see if C929's maiden flight comes equiped with CJ-2000, I don't mind being optimistic.
