Chinese Engine Development

But for which airline? Do you think any Chinese airline would buy an uneconomic aircraft if they can get more economical ones in the West? ... but this is no longer a PLAAF large aircraft and transport issue.

Could be for the C919, but it's just a stop-gap engine before the CJ-1000 becomes operational. High bypass design is a logical choice for the contingency of loss of supply of engines for the civilian airliner.

Just curious, how are the F135 and F119 different?

F-135 is an F-119 with a much bigger fan to achieve a substantially higher thrust and higher subsonic fuel efficiency through a much higher bypass ratio, plus provision to drive an additional external fan via a clutch through the front of the engine.

Just the usual “we must meet deadlines because of Xi Jinping thoughts blah blah blah” garbage. Typical bags with no useful info other than that CJ1000 will meet a deadline this year.
Do foreign component suppliers need to be wary of Xi Jingpings mandates? I thought cj1000 would be in temporary cold storage after AECC getting into the prestigious sanctions list.

How do they meet the deadlines despite the sanctions and barriers?

More advanced in every way?

AECC isn't banned from importing foreign products*

But could be. Foreign suppliers need to obtain licenses, it seems. So the CJ1000 seems more like a technology demo endeavor rather than a reliable engine which can be upgraded and serviced long term.

Things would be more bright if China initiated a program to replace the component supplier with Chinese or Russian ones. Anyway...

Requiring licenses for engine intermediaries isn't an AECC specific sanction though if you deal with that political uncertainty anyway, would surprise me significantly if they weren't already working on replacing it
