No.

 

[Deino]

No.

So it is only a test for this certain configuration ?

I think it is conducting external weapon testing

Indeed ... interesting or even funny, that so far we have not seen any clear images with external stores - IMO only two ! - and that the first were posted about one year ago.

According to the leader of 毛发党, the WS-15 has just finished the ground testing, and it is ready to pass the test on the IL-76 platform. While the current J-20A uses the AL-31FM2, a special customized edition of the AL-31, also a joint development between China and Salut, just like the GT25000.

While many people in the CD would purposely discard the news about the WS-15, they would only select the information that suits their own agenda. The guy's words were gold when he claimed that J-20 "undoubtedly" used the AL-31F, but those anti-Taihang trolls suddenly thrash him now because he has revealed the good news about the WS-15.

BTW, the revealing specs of the WS-15 seems to be surprising, it looks that China is aiming for a 180KN and TWR 11 high specs fifth gen turbofan jet engine.

The WS-15 seems to pass the ground testing by August 9th 2015.

Indeed no offence ... but first the tanks on the J-20 and now Your confirmation concerning an AL-31FN-version, that really made my day !

Like I said since so long: similar to the once and long still secret original AL-31FN for the J-10 the CAC chose a similar approach for the J-20. And since these are not exact AL-31FN Series 3, they were never mentioned or included in the number of engines reserved for the J-10B and J-10C.

Would be interesting to know the specific thrust of this engine. If it follows the regular FM2 about 145kN should be assumed.

He claims that the specs of the AL-31FM2 are similar to the 117S, that's why China doesn't need the 117S for the J-20 anymore.

However, I still insist that few other J-20 units use the WS-10G, since those different engines are clearly close to the WS-10 family. Just like few units of the J-10B/C also use the WS-10A/B engines.

The openly circulated images of 2011 show it has already tested 2 different types of engines at least. Note the right engine at the second photo appears very different to those AL-31. When taking off, its divergent nozzle provides same trust as the left one.

No, not again ... why again trying to assume that a WS-15 is already flying when just reported that the WS-15 is ready to enter tests onboard the Il-76LL-testbed and the same can simply be explained with different nozzle-opening-settings?

 

[krash]

Learning Chinese is very easy.

And typing in english even more so.

Yes but relying on Google Translator in such matters would result in disaster hence asked so I can understand better.

And the fact that it's against the rules.

Could You please provide a source or the original Chinese language post he is citing especially where it mentions 180kN and 11 TWR ?

Thanks in advance,
