if you looked at the stuff they displayed at Zhuhai air show, everything is getting there, but testing and validation take time. And continuing to import is a viable solution.

What we've been talking about recently is more the advantage they will gain from going hybrid here. Even if they go hybrid, they still need fan blades and compressors.

You should read this report
It's long(793 pages and external links) but covers nearly everything about the past, present, and future of US-China economic, technological, and military competition.

From what I understand CJ-1000A switched to its own suppliers in China a long time ago.

Those countries are not the only ones making such technologies either. The Russian PD-14 engine for example uses hollow titanium fan blades. The technology has been losing favor against composite fan blade technology, which makes it much easier to make the fan blades of the shape you want to make, and is much lighter.

i just saw this post ..

you are new member on this forum. and i strongly suggest you to please read Engine thread if you have time. we have thoroughly discussed this topic. and we posted some really valuable information about China's turbofan Engine industry..

now back to your question..

CJ-1000A don't have a single core component from any foreign company. i repeat CJ-1000A don't have a single core component from any foreign company be it MTU , RR , Safran or Avio.



CJ-1000A have wide chord fan blades made with carbon fiber reinforced resin-based composite material .. this blade showcase during 2022 airshow. i m posting the image directly from the show in 2022.

so how on earth UK is the supplier of titanium alloy hollow fan blades ?? China literally taken one step ahead to install more advanced fan blades. that too announced back in 2022.
---------------------------------------------------------------------------------------------------
High pressure compressor of CJ-1000A has also been developed by a Chinese company.. MTU didn't even take participate in bidding let alone they are the supplier of this major component

This is complete list of MTU projects in all Engine globally ..

MTU is a public traded company so they cannot hide such a big deal.. check out the list of Engines in which MTU have taken part as a supplier.
-------------------------------------------------------------------------------------------------

This foreign suppliers news first emerge in 2014-15 and continue to drag about few more years but it has been now vanished. coz there is no truth in this..

you have literally posted a decade old information.
