So in summary - and pardon to ask, but the last three days have been more than busy - the rumours about a new common airframe, likely a twin-engined B757/767-sized aircraft are true, but the claims, its engine is based on the CJ2000's core is wrong?
Yes.
Now, I think it's better to let me make this situation clearer for everyone's reference:
#1 - The rumor/claim of Xi'an AC working on a new common special mission aircraft platform project (with the aircraft size/MTOW that is either similar to the Boeing 767 or situated between the Boeing 757 and Boeing 767) is true.
However, at the current stage of development, I am in no position to declare that this project is 100% guaranteed to become a reality, only that I would say that we may be able to expect this aircraft to become a reality within the next couple of years if the project does become a success. Hence, I would retain the rating for this project at "
3 - Maybe exists, some models that may bear some resemblance to something, some rumours from some credible sources".
#2 - The 25 ton-force turbofan engine meant for this purported new common special mission platform aircraft (and most likely shared with the Sino-C-5 as well) would be a brand-new design (as the notion of developing a 25 ton-force engine using the core of the CJ-2000/directly scaled-down from CJ-2000 is deemed nonsensical/ridiculous).
