we had an Avic representative at Zhuhai airshow say in an interview that ws10 family of engines goes up to 140 kn. So that's close to 14 tons, logical conclusion being some latest variant might provide that much. Now we know that variant is ready.

To say ws15 provides 14 tons would equate ws10b with ws15. Furthermore, for all the internal volume j20 has, 14 ton engines can perhaps be interim engines and are certainly not enough for using up all of the potential of the platform. 15-16 tons or more sounds more suitable.

Finally, source for 14 ton figure for ws15?

Wait, where in the last few posts did anyone say WS-15 was 14 tons of thrust? I was under the impression that was for WS-10B... and that WS-15 was always going to be a 17 ton thrust class engine.

I think it's been known for a while that this is the 14 ton thrust engine.

you can never be too sure on this, but the Chinese sources indicate that it was flown on flankers first before J-10. So I can only assume that there are 2 versions with different gearbox location.

And hence implying that the J-10A can be fitted with WS-10 engines & exported?

ifno one claimed it then my postwas erroneous and i apologizefor the confusion.

Ok, can someone fill in the blanks?

---

WS-9 Qinling: 91 kN / 9,300 kgf
WS-9? Qinling-2 : 98 kN / 10,000 kgf (No word on this engine since 2010)

---

Original WS-10: 132 kN / 13,400 kgf
WS-10 version entered service with J-11B: 125 kN / 12,800 kgf (reduced thrust due to reliability issues?)
WS-10B: 137 kN / 14,000 kgf

---

WS-12: ? kN / ? kgf (clueless about this one)

---

WS-13: ? kN / ? kgf (heard nothing for a long time)

---

WS-15: 154? 165? 180? kN / 15,7000? 16,800? 18,350? kgf (heard nothing for sometime. Nothing concrete)

So, despite all the initial headaches with the WS-10, looks like Shenyang Liming is the bright spot here. After all the WS-10 have evolved enough to power the single engined J-10B. Biggest concern here is Xi'an and the WS-15.

Nice ... and missing are the small WS-11, reportedly a licenced version of the AI-35TLK (used in the JL-8 or even JL-11, however I never heard about this type other than at Wiki !

).

But is there also a WS-14 ?

Yup, I dropped the WS-11 since it wasn't in the class as the others. I also didn't include High-bypass TF like WS-20.

WS-14? Never seen that designation. Could it be that bad luck thinggy? J-20 skipped 2014 maybe WS series decided to skip WS-14 and go to WS-15???

I had a similar thought ... but at least there was a WP-14 - the Kunlun - ... and since this was a failure, the WS-14 could have been skipped !

actually, Liming is normally considered to have been the more incompetent one. Xi'an achieved design and production certification much faster with WS-9. We have rarely heard any issue with WS-9 engine. And remember, XAE is also involved in WS-10 production.

WS-15 has in the past year entered the phase of going through with design certification and high altitude testing based on the same article.

Never heard of WS-14. WS-13E has entered production i think.

Does that mean we'll soon see WS-13 engines on the JF-17?
