Yes the most recent two batches of J-10Cs use WS-10, as well as those exported to Pakistan. However, the J-10D (strait back version) appears to have reverted back to AL-31FN. And the jet in this picture is ...new? If new, then it is possible that Salut could have won new contracts with Chengdu. Also, one reason why J-10Cs had to switch to WS-10 was because the allegedly degrading qualities of Salut's products. Quality control appeared to be near-non-existent in Salut. There was an incident back in late 2010s when staffs at Chengdu discovered foreign objects like human underwear inside imported AL-31FN engines.
Apparently the picture here is new in the sense that it’s a never-seen-before number, not necessarily newly produced.

Just in short, there is no J-10D, it is a dedicated CY for the Ba Yi and most likely since the J-10Cs at the same base also use Russian engines, they are equipped with them too.

nope. AL-31 contract have expired in 2020 and PLAAF didn't renew. Russian engines are now history in Chinese armed forces. AL-31 become the headache for PLAAF due to poor service life and TBO. and after WS-10, they are facing difficulties to manage two different type of machines. extra cost of maintenance

They’ve even started putting WS-10 on J-10S.

they have enough AL-31 engines in storage. so why wasting those so they decided to uses those Russian machines. J-10D variant will enter in service with domestic engines.

Shenyang aero engine institute have ramped the production of WS-10. they are producing engines way more faster than SALUT coz of pulsating assembly line. and WS-10B/WS-10C performance exceed any AL series engine.
Great point! Remember taking to some distant relatives from Chengdu (where some of their friends worked on the J-7 and J-10A projects) back in April 2010. I asked them about the prospect of Chinese turbofan engines, and they told me either "impossible" or "extremely difficult." They marveled at Russian TVC systems and complained helplessly about China's then "inferior" aviation industry after a few shots of Wuliangye. Looking (and some of my Chengdu distant uncles have passed away since, sadly not being able to see the J-20 and WS-10 entering service en masses) back, it is indeed history, especially how far China has come along.

i m closely following the Chinese high tech development/progress since 2010's decade.

in 2012 China issued a white paper about turbofan engines. 'we are the only country in UNSC P5, that couldn't design and produce own turbofan engine'. seriously lacking this sophisticated industry and could have huge consequences on our national security.

this was the China's official statement back in 2012.

exactly in just 10 years, China have build complete ecosystem of aero engines. and now producing every type of gas turbine engine. conquered each and every tech in this highly sophisticated machine. now marching towards cutting edge aero engine technology. by 2030 China will be leading player globally along with USA/UK in this sector.

difference between 2012 China and today's China is like heaven and earth.

gas turbine engine
Still struggling a bit with regards to high bypass turbofans, but pretty it will be resolved soon with WS-20 entering service on Y-20Bs (and hopefully CJ-1000 on C919 ASAP, but civilian aircrafts have higher standards on fuel efficiency). At least with WS-10 on J-10C single engine aircrafts, China is now in a position to play hardball in the military engine market. The next step is to see if the WS-15 series could be the choice for J-20Bs and 6th gen fighters.

Guys ... can we come back to the J-10 and anyway - honestly - I don't understand this fuss?!!

AFAIK all J-10Cs delivered to the 131st Air Brigade like this one no. 74826 spotted at Zhuhai today (cn. 0421) are Batch 03 and 04 J-10Cs, which are all powered by AL-31FN Series 3 engines.

J-10C cn. 0421 - 131. Brig.jpg

Only from the mid of the Batch 04 on (in fact we know one 042x aircraft being the first), they started using WS-10B and since then all Batch 05, 06 and most Batch 07 are powered by WS-10B engines!

In fact NONE has been fitted with AL-31FN until this mysterious one numbered 701! As such I assume, that up to at least cn. 0720 they are all WS-10-powered ...

... all but the no. 701, which is also so far the sole one confirmed with the spine. But anyway, they are Batch 07 J-10C and NOT J-10D!

well, you should check my all posts on 'Engine development thread'. will be helpful for you.

high bypass turbofan engine problem solved too. WS-20 serial production has begun. its successor means heavy thrust engine is also under development. Shenyang aero engine institute rolled off their gloves. LOL

CJ-1000A engine took off China's high end manufacturing. with all core components being produced by Chinese institutes/firms.

this is my last comment about engine on this thread. if you have any question plz do ask in engine development thread.

sorry guys
