Chinese Engine Development

Perhaps part of the answer is the name. Note it is not WS-10, but FWS-10. I wonder what the F stands for.

When I first joined this forum the first thing I posted about was the different number of static vanes in the WS-10 engine from that billboard at the 2006 Zhuhai airshow and the one that was on
display at the 2008 airshow.

The billboard photo of the WS-10 in 2006 had 15 static vanes.
Two years later (after design certification) it had 17 static vanes.

The engine in the photo above only has 15, so this engine is a pre-2008 design.

In fact, there are a lot of differences between this engine and the 2008 WS-10a. Perhaps this is the pre-2006 WS-10?

I don't think so, this engine was put on CHina aviation museum. So what it stated carries some weight. The description clearly state it has enter mass production phase. In our knowleadge, WS-10 never enter mass producetion phase. Only WS-10A enter mass production phase.

Good news. Just as what u wanted.

"It mention it is an local develop advance turbofan which priority will be equipping J-10. It can also equip J-11B. Presently , it has enter mass produced phase."

More or less, we will see J-11B chunk out like hot cakes soon and J-10a start using WS-10A.

This depends on how recent the information in the panel was last updated. We know that mass production started quite some time ago before problems started cropping out.


"Perhaps part of the answer is the name. Note it is not WS-10, but FWS-10. I wonder what the F stands for. "

I believe they are the same. The FWS-10 is the official designation.

This is not the engine that was displayed in 2008. It has many differences.

Got me wondering too.....

There are huge differences between engines. Unless I am missing vital piece of information?

Can I say one thing? The FSW-10 exhuast blade may look quite similiar to AL-31F if fitted on J-10A or J-11B... While WS-10A on Zuhuai 2008 air show looks different and can be distinguish easily if fitted.

Thought I'll add few more for comparison sake...

Pratt & Whitney F100-PW-220 :


AL-31F :

I think FWS-10(a) is the official designation. WS-10(a) is just the shortened and more common name.

I wouldn't doubt that some of WS-10a's technology comes from the AL-31F/CFM-56.

But these engines are notably different. That is what is confusing.

For sometime it was believed/rumored that the WS-10A core was based on the CFM-56 core.

Actually, the more I think about it, the more I think that the differences we are seeing might have something to do with the plane that each engine is designed for. After all, the J-11's have AL-31F and J-10's have AL-31FN's. They are both the same engine, but modified to suit specific needs. How can the WS-10a suit the needs of two types of aircraft? The engines would need to have modifications, and thus have different designations to distinguish them.

I know its not likely, but is it possible that WS-10 is the name of the engine for the J-11B and WS-10a is for J-10?

It would make more sense to have a subdesignation next to the name rather than different letters which are more major variants.

Shanghai, China - Ready by 2016, it should replace those supplied by western companies
(WAPA) - An engine model for the new COMAC (Commercial Aircraft Corporation of China) C-919 airliner has been unveiled at the "China International Industry Fair 2009" in Shanghai. The SF-A engine, designed by AVIC (Aviation Industry Corporation of China) Commercial Aircraft Engine (AEAC) should be produced starting in 2010.

According to the manufacturer, this engine satisfies all the necessary requirements to power the C-919, the largest commercial aircraft produced in China, which should enter into service in 2016. COMAC will chose its main suppliers by the end of the year, and already announced that at first it will chose western-made engines. However, it hopes that Chinese suppliers might replace them soon.

The SF-A engines will be ready in 2016, but AEAC said that it will take several months for them to get all necessary certification to make them suitable to be installed on airliners. (Avionews)
