I disagree with your statement. Surely, China WS-10B and WS-20 are not the level of F110 and CFM-56 in the 1980s.
WS-10B is rated 14500kg thrust with afterburner. Do F110 engine can have such thrust in 1980?
Same as the CFM-56 which has introduced plenty of version even up to years 2000 with...
ARJ21 is just an temporary product. With signing of China eastern airliner confirm buying 5 C919. All Chinese airliner are aiming for C919 rather than ARJ21 as it can carry more passenger with much lower operating cost per person. It tech is also much newer, ease of maintenance and cost.
ARJ21...
Deceived? Given your logical thinking. After so much saga, PA shall have long purchase Z-10ME long ago even before reaches this stage. And yet, with so much questioning, PA still pursue for T-129K.
There is a limit China can give loan. We have already given loan for 054B frigate, AIP submarine...
A very very big reason why PA chooses T-129K over Z-10. Also why PA willing to drag this long even they know such big issue prop up over the engine available.
Free money vs paid upfront cash.. You dont need a genius to tell u to pick which one.
Bigger than Saturn V.
The rocket besides CZ-9 is very interesting... Its seems to share same diameter like CZ-5 with more powerful rocket propulsion but smaller than CZ-9.

The Civil Aviation Authority of China (CAAC) has certificated the WZ16 turboshaft that will power the...
The CH-5 with uprated turbo shaft can have payload up to 1 tons. 16 ATGM. Not to mention unmatch attitude and loiter time which attack helo can't matched.
I don't think attack helo now is a priority for PA. Unmanned attack drone are getting more sophisticated. They can loiter longer time and best of all suffer no casualty.
There is reason why PA bought a batch of CH-4B recently. Priority shall be for by tanks, submarine and new block 3 of JF-17.
