Come on guys … when have we seen the last newly-produced J-11 powered by an AL-31 ?? … as such the PLAAF is quite confident with the TH and at least by all reports we gathered it’s truely a problem of production rate / capacity and not of reliability or capability of the TH.

«Рособоронэкспорт» заключил с минобороны КНР контракт на поставку авиадвигателей на сумму свыше $500 млн. Снабжать истребители собственными моторами китайцы пока не могут

Контракт на поставку 123 авиадвигателей АЛ-31ФН до 2013 г. на сумму свыше $500 млн «Рособоронэкспорт» заключил с минобороны КНР в начале июня, сообщили «Ведомостям» источник, близкий к руководству «Рособоронэкспорта», и менеджер одного из предприятий авиапромышленности. По словам последнего, первые 13 двигателей будут поставлены до конца текущего года. Выполнять контракт будет московский завод «Салют», который и ранее поставлял двигатели этой модификации в Китай: 54 единицы по контракту в 2003 г., 100 — по контракту в 2007 г., 122 — в 2009 г.

… and also …

China’s Ministry of Defense signed a contract to buy Russian aircraft engines worth $500 million in early June, Vedomosti reported, citing an unidentified personsource close to Russia’s state arms-selling agency and an unidentified manager of an aviation company.

The contract is for 123 AL-31FN engines by 2013, the first 13 of which will be delivered later this year, the newspaper said.

Seems as if we have to wait a bit longer for a TH-powered J-10.

Another one ….

@Corran
First of all HELLO here on borad, but second …

J-11B? What is J-11B? There is absolutely no reliable information on that airplane. Many here say that serial airplanes are using WS-10 engine – I very much doubt it. I saw some pictures of test airframe Su-27 with one AL-31 and one WS-10, WS-10 is bigger and requires the whole engine bay to be modified.

Come on … YES, we don’t have much realiable information of the individual avionics fit, but we know for sure it has a new radar, new cockpit with MFD’s + HUD, several other items and most of all from block 02 on it is powered by the WS-10A Thaihang. Honestly I can’t believe that You still doubt that since there are so many Chinese reports on that, we have high resolution photos – maybe not that clear as we all wish – but surely good enough to say for sure it’s a new engine.

At the moment there are at least four operational regiments flying already with these new birds or just under conversion … and they are surely not simply painted AL-31F’s.

As such to deny these changes and esp. the new powerplant would be plain stupid.

Besides that, the one with both engine with that “larger diameter + modified engine bay” (IMO not necessary different, since the TH was developed to fit the standard bay), that was the prototypes WS-10 not to confuse with the serial WS-10A !

As for J-15. Chinese have acquired one of the Su-27K (now called Su-33) prototypes from Ukraine. I believe that with their know-how on Flankers they are capable to make it into flyable condition. And not much more. The crazy idea that the carrier based J-15 is flying on WS-10 is just ridiculous as this engine is far from being mature and that carrier use is much more demanding on the aircraft. The original Su-33 use special AL-31 variant that for short period of time can give additional thrust comparing with the standard AL-31 (it probably works similar to R-25 engine from MiG-21bis).

Then again You seem to ignore the latest photos & reports – maybe You are bettere familiar with the scene on Russian aviation but not on Chinese !? You are correct that the first and second prototype flew with the AL-31F, but the latest – the grey one – is clearly powered by the same engine like all J-11B, BH, BS & BSH are powered. Again – and I’m surprised too – but You should believe that “crazy idea” even if You don’t want to !

As such … and that again seems to prove the other reports, the PLAAF and PLANAF together with SAC are quite confident enough in that engine.
and finally …

My conclusion is that JF-17, J-10 and J-11B radars … . Engines:AL-31 or RD-93, the WS-10 is not 1 on 1 copy but is heavily inspired by the AL-31.

Again that might be Your conclusion even if already known that the TH is not to a minimum based on the AL-31F but related to the CFM-56’s core …

Hmmm … could it be that this is only a mock-up ? :confused:

… besides that, two more flights (now 19) yesterday !

Its time to have another good laugh over the jokes come regularly from russia::diablo:

YES … like I already in the general news tread about that post, since everytime I read such comments … I remember an answer like this (from a nice guy at SDF): :diablo:

If you have made something which is clearly superior to something someone else has produced, would you ever really feel the urge to bash the other person’s work?

China’s engineers and officials have said little about the PAKFA, but Russian officials and designers have been lining up to bad mouth the J20 to everyone who would listen and their dog.

You can all make your own minds up on who feels confident and who feels threatened.

T-50-1 and T-50-2 together made ~​​70 flights.

Thanks !
