Chinese Engine Development

Chinese-made engines are currently used in the twin-engine J-8, which is based on the design of the Russian Sukhoi-15 fighter, but these are still being adapted to the far more rigorous demands of a single-engine jet.

LOL
Article must have been written by an expert.

Right, an expert who thought it's a matter of adapting a turbojet into a turbofan.

The story sounds very much like the old one and I bet they are the same.

Only goes to show how hard is to get an reliable china military source

This source seems to claim that China has two J-10's equipped with WS-10a.

yeah, I took a simple look at that entry, looks to be completely nonsense. Too many mistakes on the basic facts of J-10.

Some news on the turbofan engine for the large transport project.

我国已初步具备研制大型飞机的条件和能力
建国50多年来，我国航空工业共生产了各种飞机16000多架，发动机近6万台，为国防建设和经济发展做出了重要贡献，已形成比较完整的航空工业生产体系。已配备了一定数量的数控切削设备和100吨以上的数控钣金成形设备，正在修建80米跨度的装配厂房。大型运输机需用的大涵道比涡扇发动机 FWS10-118验证机，己正在进行地面台架试车。完全可以说，目前我国航空工业已初步具备了研制150吨级大型运输机及其动力装置的能力。
抓住机遇、早作决策
研制大型飞机是中华民族复兴的一件大事，也是时代赋予我们的历史责任，势在必行！搞大型飞机可能需要10~15年或更长的时间。大型飞机工程论证，从两院院士向党中央、国务院提出咨询建议算起，五年多时间过去了。发扬技术民主，进行充分的论证和讨论是必要的，但长时间过多的争论却于事无补，只会白白丧失难得的历史性发展机遇，这是我们大家都不愿意看到的。

This part here indicates that the large bypass turbofan engine is called FWS10-118 (or at least the prototype is called that, the developed version might have different title). It is built to power 150 ton class transport. This engine has already started doing test runs.



Both articles are from Xi'an AeroEngine PLC. They talk about a major project is award to XAE. They claim that this is for the large bypass turbofan engine project.

Keep in mind, XAE is already the main stakeholder for the WS-9 and WS-15 project. It also does 1/3 of the work for the WS-10A and the majority of work for QC-280.

I think XAE should get all aircraft engine work. Much better to centralize R&D and production in one place

By WS-15, is it that new engine with the T/W ratio of over 10:1 or just an improvement of the WS-9?

i think you still want to split up work to foster competition. but they are definitely awarding bigger projects to xae.

over 10:1

last week report that China and ukraine sign aggreement to develop 12 ton thrust engine for civilian aircraft.it is possible the engine may be FWS-10-118
using Ws10 core technology to developed high bypass TF.

I was surfing Chinese internet and came across this photo of what appears to be J-11B production or testing. It appears to be equipped with WS-10a. I showed my Chinese friend, he says that the program this capture came from is relatively new, meaning it was filmed, at earliest of late last year.

It looks like ws-10a to me, but I'll leave that up to you guys.

Also, note, as I have pointed out before, that the J-11B has no green primer (unlike the prototype). I do not believe that composites ever made it into the production version. (Nor do I believe they really reduced the RCS to 5 meters, but that is another story).

That's a J-11BS on the lower right.
