It looks like the WS-17 is being inducted on production JL-10a. The UAE L-15 will get it also!

New "heart" on the modified L-15 Falcon:

J-10 prototype 1004 is very important in China's aviation not just as one of its first J-10 fighters to take to the air but also the first single-engine to fly with the WS-10 engine!

With the original AL-31:

In 2004(!!!) with the WS-10:

After quick reading 36 pages :drool::fyeah: the following is a short timeline compilation of engine updates only on fighter jets of FC-31/J-35, J-20, J-10 :

J-35
1Aug'21: WS-13E for FC-31; WS-19, 110 KN for J-31/35; smokeless WS-13 variant on FC-31 V2
17 Jan'22: WS-19 T/w ratio > 10
20 Jan'22: Wikipedia - WS-13E 100KN; WS-19 110KN 12-ton thrust for JF-17, FC-31.
but in Jun'24 - 86.37KN 9-ton thrust T/W 7.8; WS-19 98.1KN for J-35, 10 ton thrust.
22 Jan'22: FC-31 V2 early with WS-13 engine; FC-31 V2 late with WS-13E engine; J-35 1st in green color withWs-13E engine
21 Feb'22: WS-13 (base): 86.37 kilonewtons (kN); WS-13A/IPE: 90-95kN; WS-13E: 100kN; Dec'2016 1st flight of FC-31 V2 with WS-13E engines
27 Jul'22: WS-13E revealed to be renamed as WS-21 for J-35; Chinese net speculations that J-35 35003 serated nozzle may be WS-19.
14 Nov'22: Model of J-35 with 2D TVC nozzle at airshow.
8 Feb'23: WS-21 is officially a separate engine type now. Many originally assumed it was a variant of the WS-13.
1 May'23: WS-13E on FC-31 V2 & WS-21 on J-35.
2 Mar'24: WS-13E/21 at 100 KN; WS-19 flight tested on IL-76.
----------------------------------------------------------------------------------------
J-20
1Aug'21 WS-15, 180KN
17 Jan'22: WS-10C on J-20
19 Jan'22: 2 engines tested on J-20
20 Jan'22: Wikipedia - WS-15 181.37 KN for J-20, 18 ton trust, T/W 9-10.
but in Jun'24 - 156KN for J-20, 16 ton thrust, T/W 9-10.
22 Jan'22: WS-10C engine of the J-20A! The third production batch which incorporated the WS-10C has at least 56 planes!
26 Jan'22: WS-10C is better than AL-31FN3/4
4 Feb'22: WS-10C on J-20. WS-10 TVC or WS-15
13 Mar'22: WS-15 announced for both J-20 & medium jet probably J-10.
15 Mar'22: WS-15 tested on J-20
30 Apr'22: Japanese article says WS-15 tested on J-20 has 15-18 tons thrust
27 Nov'22: WS-10C J-20A 155 kN
14 dec'22: Liu Daxiang confirms the flight test of the WS-15 on J-20. 180KN thrust, T/w ratio 10.
7 Apr'23: suspected WS-15 engine on J-20
19 Apr'23: WS-10C for the J-20 would be over 150kN (WS-15 is cited at 180kN.)
29 Jun'23: WS-15 tested on J-20
30 Jun'23: WS-15 afterbuner thrust is 171.3-191.6 KN.
3 Jul'23: WS-15 afterburner thrust is 160-190 KN with T/W ratio <=10. WS-10C has 147 KN.
18 aug'23: WS-15 on J-20A
2 Mar'24: WS-10C on J-20 is at 155 KN; WS-15 at 180 kN on J-20 test; Production: J-20A
----------------------------------------------------------------------------------------
J-10
31 Jan'22: WS-10B on J-10C
15feb'22: WS-10B on PAF J-10CE
27 Nov'22: WS-10B J-10C, J-11BG, J-16 144 kN
19 Apr'23: WS-10B on the J-10C is at 144kN
2 Mar'24: WS-10C on J-10C is at 155 KN

What confident details do you have on WS-19?
After checking all links on 1st page of Google search i found multiple specs -
(Afterburner thrust / engine weight) ratio = 10.
Afterburner thrust = 98 - 124.7 KN / 10,000 - 12,727 Kgf / 22,000 - 28,000 lbf.
Dry weight = 1,000 - 1,272.7 Kg / 2,200 - 2,800 lbs.
Dry thrust = 78.45 KN / 8,005 Kgf / 17,611.2 lbf.
(Dry thrust / weight) ratio = 6.3 - 8.
(Dry thrust / Afterburner) % = 63 - 80 %
(Afterburner / Dry thrust) increase = 25 - 59 %
Bypass ratio = 0.3
Dry thrust fuel usage (g/KN/s) = ??
Afterburner fuel usage (g/KN/s) = ??
Air flow (Kg/s) = ??
Compression ratio = ??
# of fans, compressors & turbines = ??
Turbine inlet temperature = ??
MTBO = ??
Lifespan = ??

No official details even less than WS-15. The watchers' concensus is wet thrust at 110kN.

124.7 is way too high. WS-13E and WS-21 are tagged at around 100kN so a modest hike to 110kN along with longer life and MTBO seems reasonable.
