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.

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.

China built its first commercial scale civil aviation tire production line. Located in Guilin, Guangxi, this production line is "digitized" and can produce 100k tires per year to meet a third of the annual domestic demands.

On Nov 21, an Airbus 320 completed the flight tests for China's first domestically made civil aviation radial tire.

我国首条规模化民航轮胎生产线建成投产
Click to expand...
据中国中化控股有限责任公司微信公众号“中国中化”21日消息，中国中化旗下桂林蓝宇航空轮胎发展有限公司（以下简称“桂林蓝宇”）在广西建成国内首条数字化民航轮胎生产线，每年可生产10万条高性能民用航空轮胎。

中国中化文章显示，11月20-21日，由桂林蓝宇研制的中国首条民航子午线轮胎装配空客A320飞机试飞圆满成功，填补了我国民航子午线轮胎适航取证空白。

此次试飞由桂林航空一架空客A320飞机在桂林两江国际机场执行，这也是空客系列飞机首次装配我国自主研发的民航子午线轮胎。

此次试飞使用的是桂林蓝宇为A319/A320飞机新研发的民航轮胎，是基于热力耦合构型优化、关键橡胶材料模量匹配优化等创新技术研发的高性能民航子午线轮胎，具备完全自主知识产权。该航胎于2024年9月通过动态模拟实验，10月获颁中国民航局CTSOA证书（技术标准规定项目批准书），11月完成装机试飞。

整个试飞过程严格按照适航部门批准的试飞大纲，分为半构型和全构型以及干、湿跑道三大科目共计9个验证项目，顺利完成多次正常起落。中国民航中南管理局、桂林航空总工程师和技术专家在现场审查了整个试飞过程。

试飞结果表明，空客A320使用桂林蓝宇国产民航轮胎符合适航要求，所有试飞项目全部成功，获得试飞机组的高度评价，认为国产民航轮胎操纵感觉良好，滚转稳定性和抗湿滑性能优异。

近年来，桂林蓝宇根据民航轮胎多学科集成创新的特点，组建了国内唯一的民航轮胎国家级创新中心开展协同攻关；建成了可模拟全项复杂起降工况的民航轮胎模拟测试平台，大幅提升我国民航轮胎的研发评价能力；建成国内首条数字化民航轮胎生产线，通过高度自动化确保质量稳定性，已形成10万条/年生产能力，约为全国民航轮胎消费量的三分之一。桂林蓝宇正在规划民航轮胎全谱系覆盖的研制目标，全力保障民航轮胎产业链供应链。
