Chinese Engine Development

@manqiangrexue - over the past few years, SDF posters have seen many claims of Chinese engine development that turned out to be false. An example is the WS-10 engine. Therefore, it's only reasonable for rational readers to wait for official statements from factories or the government. Meanwhile, it's fun to speculate, as long as it's not taken too seriously.

1. WS-10 is not an example of a false claim. It is a working and operational engine.
2. We can absolutely wait for official statements from the factories or government... then make that a requirement for all your sources, even those that say WS-20 suffered a shaft break. Did you see those as cited sources when you said the post was rational?

10. The WS-500 was recently mounted on a UAV which was launched via EMALS. That is news to me! When did a UAV equipped with a small turbofan get launched using EMALS?

Was this to test an exceptionally light plane to test how well the the EM cat can handle that or was it a small EM cat for use in small flattops carrying helicopters and UAV's? I would be surprised if, in case it is the second, we get that information soon.

Shaft material is hard to manufacture, even Japan has problem with it and have to licence technology from Sandvik and imported the machinery and tech assistance from Sweden. China don't have access to that kind of technology. She has to invent it herself!

why were you comparing it to Japan ... unlike China .... Japan imports all high performance turbofan engines and also imports (or license) most (if not all) main weapon system, mainly from the US

1. IS EMALS short for Electro-Magnetic Aircraft Launch System? Please correct if I am wrong.

2. Any news about WS-13? I read somewhere that WS-13E is ready to be fielded. I would really like to see it on FC-1 / JF-17 if it is mature and ready for use.

Because even Japan which has long tradition of building aero engine .Even they need a partner to fabricate turbine shaft.

Material science depend on skill and long experience, trail and error It is not exactly exact science. European has the lead since they initiate the industrial revolution.

For your information Japan(IHI) did build their own turbofan engine first to power Kawasaki maritime patrol. They are pioneer with ceramic blade


Even the latest Shin shin demonstrator use their own domestic engine


They don't have engine in 130 KN engine class or T/W ratio of 8 or more. But that is because they were prevented from developing their own aircraft industry. In the late 80's they were planning to developed their own fighter jet

Were that program goes thru I bet they will developed high power Turbofan engine.

So Japan is heavy weight when it come to Jet fighter after all they built thousand of zero, kawasaki, nakajima etc

Well, I remember some posts in CDF and twitter post.



thanks to @Deino



showed the UAV at PLAN training airfield. the upper cat lane is the EMALS one.

But for me two questions remain:

1. is the source you mention reliable? how serious can it be taken when he states a UAV has made test flight from the EMALS? until now, I've not seen any proof, that the EMALS there is working. Only stills where published.

2. is there any proof or at least a second credible source that EMALS is working?

well, something easy to google. But the answer is yes.

As supplemental information.

The responsibility of a 70-80 % global share

Inside a charming, time-worn brick building that once flourished as a shipbuilding works, state-of-the-art technology is being applied to create jet engine shafts. There are over 30 main types of jet engine shafts being produced, primarily for the three global manufacturing leaders General Electric(USA), Rolls-Royce (UK), and Pratt & Whitney (USA).
When low-volume specialty parts are included, the number of shaft varieties is approximately 50. Roughly 4 000 shafts are manufactured per year.

Is there any high performance turbofan engine produce by Japan? manufacturing parts and design & build HP turbofan are two different things ... just in case you don't know (but I am sure you do especially with the help of Dr Google)
