Got this from someone. Take it with a grain of salt lol
Here's a little summary I made some time ago:
DO NOT TAKE THE FIGURES I LISTED AS FACTUAL. THEY'RE MERELY FOR REFERENCE, AND NOT OFFICIALLY CONFIRMED.
WS-9: Based on the Rolls Royce Spey. Used by JH-7/7A.
WS-10 series: Low bypass, high-thrust class, equipped on J-10C, J-11B and later models, J-16, interim engine for J-20 (WS-10C), and soon to be equipped on J-15B. Basically equivalent to the F110. Developed from the CFM-56 core, with AL-31 characteristics. Dramatic improvement in TBO time, thrust, reliability, etc. as development went on. There's also a 3D TVC testbed equipped on a J-10. WS-10B *allegedly* have a wet thrust of ~130-145 kN. WS-10c (141kn 32000 lbf). WS-10g (152-155kn 34000-35000 lbf)
WS-13: Low bypass, medium-thrust class, developed from RD-93. Equipped allegedly on the JF-17, and FC-31/J-35 prototypes. Developed into the WS-13E/21.
WS-15: Low bypass, high-thrust class, potentially the most advanced high-thrust engine to be fitted in a twin-engine fighter yet. Indigenous design, basically the equivalent to the F119. To be fitted in J-20A and potentially the J-20S. *Allegedly* have a wet thrust of ~181 kN.
WS-17: Low bypass, low-thrust class, and (I believe) non-afterburning. Equipped in trainer jets like the JL-10.
WS-18: Medium bypass, developed from the Soviet D-30. Equipped as an interim option on Y/YY-20.
WS-19: Low bypass, medium-thrust class. Indigenous design, equivalent to the EJ-2x0/F414-EPE. Currently undergoing tests and to be equipped on the J-35/31. ‘Confirmed’ thrust of around 10 tonnes-force (~98 kN), but I've heard figures of a maximum wet thrust of ~112.8 kN (UNCONFIRMED).
WS-20: High bypass, based on the WS-10 core. There's also rumours saying it's based on the CFM-56-5B/7B. To be equipped on Y/YY-20.
WS-21: Also known as WS-13E, developed from the base WS-13. Improved life cycle , MBTO and thrust. Interim engine option for the J-35/31. 9 tonnes-force (88 kN) for wet thrust. Wikipedia states 100 kN though for whatever reason.
WS-6/8/12 are cancelled projects.
