Chinese Engine Development

That is quite likely the rationale, but if they don't mount composite fan blades on an actual CJ-1000A soon, chances are it will have to be introduced on an improved variant after service entry with metal blades. The very fact that ACAE took the time to develop hollow titanium blade technology also indicates a composite fan was not considered mature enough to be ready in time. Otherwise they'd have simply mounted conventional solid blades on the non-flying demonstrators and skipped straight to a CFRP solution at a later stage and for production.
Not the first time we’ve seen staggered development and component creep in Chinese tech projects that are trying to catch the technological leading. I guess there are potential issues with project management that this can introduce for a commercial project but they also have much greater control over their own domestic market and regulatory environment so...

we do know something about WS-15. There has been report of "engine casing production plan (years) for XX-15 in the number of low two digits" which certainly was about WS-15 that is in late development
Is that all we know??? thats something...next to nothing. What about any rumours or information that it has been test-flighted?

my "we know nothing" should be precisely stated as "do not easily conclude anything around WS-15".
Or perhabs can be stated as "do not conclude anything around WS-15".

1. If they had laid out a 5(?) year low volume production plan of engine casing, how likely do you think that they have not flight test the "prototype"?
2. Let's not go into a word of play. Be moderate and cautious is all that is needed, no need to jump from overly confident of something to the other extreme side of nothing and anything.

Like they say Rome is not built in the day. Expecting China to be on the same level as the west when it come to Jet engine is just plain ridiculous and delusional. Forgetting that 20 years ago air travel in China does not exist. Just getting by with food and keep the body warm is a struggle let alone travelling by Air.

Air travel and civilian jet engine self sufficiently is a luxury that can wait. For the masses China can get by using HSR to travel inside the country and she is independent when it come to designing, producing, constructing world class HSR.
But China is now independent when it come to military jet engine production that is something more important and worthy of celebration!

In what universe China was like that 20 years ago?

My, I must be getting old, there are actually young people out there like Stan who have never experienced hardship. And is unaware that the Chinese people were litually on their knees throughout the best part of the last 100 years. Gee.

ok, that's not what I mean, I should quote more precisely...

30? maybe, I don't know
20 nah, there were plenty air travel options available for ordinary people in China, well at least in major cities
I mean for common people I was in Beijing municipal airport around that time and it is awfull quiet at that time and infrequent flight. I don't mean literalllly Not like today

Yes. That's right. Aur travel was at it's infancy in China. And as such, it is a luxury item. A bit like what it was in the western world in the 1950s and 1960s. A whole 50 to 60 years behind.

My parents were travelling around China. And they told me it was just like the UK was in the 1950/60s. The airports was sparse with few passengers, and almost everyone of the travellers were wealthy westerners.
