Is it flying with these ?
From Pinko at first page.
Since this chart has been existing for quite some time now, the prototype of Ws-15 should be ready by now, possible finished or undergoing high altitude tests to this point of time.
WS-10 official max thrust is 122kn, on par with that of AL31F, even though the WS-10 reached > 130kn during endurance test, probably so that it can be conveniently exchanged with AL31F on J11s. be mindful, the Russians have stopped any AL31F for J11s, WS-10 is the only choice, and it’s mature now with massive production and consistent J11Bs/J11BSs being produced and inducted .
Now there’s improved Ws-10G, with FADEC, 1st customer most likely to be PLANAF’s J15 for better TWR needed during aircraft carrier’s taking off. However, as J-15 itself is in prototype stage, unlikely, Ws-10G could be mature at present and being installed on J20 prototype.
The j-20 main contractor, CAC has a close working relation with Russia’s Salyut, Salyut secured AL-31F contract from Saturn because of Chinese order ( CAC’s J10), and developed improved AL-31F-m1, m2 , m3 etc, solely for CAC initially, although later the Al31F-M1 became the standard powerplant of Su27SM. The AL31F-M1 reaches 13 ton max thust, slightly higher than wS-10 current allowed max thust . M2 reaches 14 tons, currently the best can be offered by Salyut to CAC, I suspect the Al-31F-M2 could have been installed in the J-20 prototype.
