Where did you hear that rumor mongering forum? As far as I know there are always 2 contending prototype for civilian airline engine . Pratt and Whitney spend nearly 3 decades to develop engine and still they have problem . So it is not unusual No need to condescendFrom what I have read the Chinese civilian airliner engine program seems to be a mess. Enough that the Chinese government, unlike usual, has two competing engine designs last I heard. Hopefully at least one of them will be successful. Not that other countries don't have their problems either. So what might happen is the engine will happen later or have worse fuel consumption/reliability or both.
