Chinese Engine Development

Sorry... got to chimp in here.

Why would you say failure to deliver after the top brass had given specific instruction will be due to corruption? There are hundreds of reasons why a project would be delayed. First off, the technology might not be matured enough, the engineers and designer might still find problems with the design, there are supply chain and logistic issues, some components cannot be made on time, etc etc.

The other example you gave is mainly due to corruption that ultimately caused disaster, it was proven to be corruption and so Liu Zhijun was given the death sentence (it is a totally different case as the above mentioned).

Unless it is proven that the delay was caused due to corruption on anyone's part, then you can see death sentence being handed out.

If its due to technology problem or lacking of the require skill and metallurgy, why would CCP top brass give out such harsh tone? I do not think CCP are that unreasonable. I bet after a deep thrashing from top brass, Liming are forced to sign the military order.

I believe such harsh tone and strict requirement dateline set by top brass for AVIC Liming is to stamp out their favouritism and corruption.

If I were CCP leaders and after seeing J15 powered AL-31F onboard the Carrier, my first reaction is WS10A ready to be mass-production for J15 ??? This is NO LONGER a testing for new platform time, it's already beyond that.


J15 should be cranking out in massive number with WS10A with 2 more domestic carrier being constructed in Shanghai.

WS10A started mass production in 2009, and now is 2013, there should be around be 300 WS10A manufactured already.


And how many of those WS10A J11B are there? Something doesn't add up.

Xi already declared China is at War-Preparation Stage. and Now is time for Serious Mass Production.

No More Fooling around.

So, you hear this kind of rhetorics all the time. Of course, it's a good thing for PLA to train to be more prepared for conflicts. And in terms of mass production, I can assure you the production rate would be a lot higher if China really thinks it's about to get in a war.

So, let's draw down this war talk and get back to engine.

Back in 2009, a PLAAF general said that the J-20 will be ready by 2018. Assuming various tests of the new engine will take 5 years, that means all the development should be over by now. If we use a less optimistic date of 2020, this means development should wrap out by the end of this year, with next year devoted to integration of the initial prototypes.

2020. for LRIP J-20 with WS-15 ? Sounds pretty ambitious to me . You would need to integrate airframe , avionics (radar) , engine and software in such short time .

Well, the J-20 has been flying for almost three years now, and in that time we've seen what looks like weapons and avionics testing already...

That means the plane is almost ready? I doubt the plane is going to do testing for another 3-4 years just to wait for the engine. And I doubt J-20 is going to commission into service with AL-31 engine. SOmething tells me J-20 has actually reach the late stage of development(Avionice and weapon testing) that included the engine. So far, nobody is able to comfirmed what kind of engine is running on J-20. Many has the assumption that the engine is AL-31 just based on the engine ignition and sprooling up.

Russian is quiet on engine use on J-20. You all see Russian do not keep quiet on J-10 and J-31 engine matter where they openly admit of their engine involved in these projects. Russian is totally not consulted when regards to J-20 testing engine. I doubt the engine on J-20 now is AL-31 engine. An nobody can explain why the engine petal on J-20 needs to be changed into silver color thing if its really AL-31 engine..

Nobody knows WS-15 engine core is based on what or a totally indigenuous design. Is it possible we see the engine sprooling up like AL-31 engine is because WS-15 core is based on the Russian design.

Another reason why J-20 is officially chosed by PLAAF is because the WS-15 engine is gurantee?
