So basically ws-15 = al-51 > f-119?
And ws-19 > ws-21 >= rd-33mk?
RD-93MA I think, similar to the newest type of the series
don’t know if it would have better high-altitude performance like WS-10 series
The WS-15 offers high-altitude performance comparable to the F-119, while slightly outperforming it at lower altitudes. The WS-19 features a technological level similar to the EJ-200, with a thrust output reaching that of the EJ-270. I’m not very familiar with the AL-51. WS-21 = WS-13E > WS-13 ≥ RD-93MA.

For specs we have this chart that compares it to contemporaries from the manufacturer. Considering the top speed of su-57 (2600 kph for al41f1 or apparently 3000 kph for the m variant with al-51), it’s clear that it’s probably the most advanced/powerful engine on a 5th gen barring maybe ws-15 (unsure if any primary material on ws-15 even exists). it’s essentially on par with f-119 in terms of thrust while being more fuel efficient. Basically a slightly better f-119.
Unfortunately no comparison to Chinese engines (al-51 is product 30)

Yeah I’m kinda confused by this. At first glance it looks like a performance graph, but it’s not showing actual thrust numbers or engine output. The axes are just altitude (km) vs Mach number, so all it really shows is the operating envelope so I think basically where the engine can run without issues?
The left side has that red shaded area with the Chinese text saying it loses fuel supply/stability at low altitude + high Mach, while the right side (I assume WS15) just says “problem solved, fuel supply full, thrust performance better.” So it’s not measured data, more like a qualitative claim that the WS-15 handles that region better.
So yeah, not thrust charts or anything concrete just “our engine works better at these conditions” slapped onto a chart

This was from “Modern Aircraft Propulsion Systems and Key Technologies Involved in Future Configurations (现代航空推进系统及未来新构型涉及的若干关键技术)” presented in the “Leading Forums No.21 (第21期领航论坛)” of CSAA.

Performance figures in academic publications and presentations like these were always vetted and filtered to not leak anything, usually not useable in a War Thunder sense.
In this case it was used to show that they were able to suppress vibration at high Mach to improve performance.

The WS-13E/WS-21 despite sharing the same name, it’s a completely new engine despite what it’s moniker suggests.
A Common trope of the PLA, an example such as the ZTZ-99A is a completely different tank than the ZTZ-99, yet it’s name suggests it as a mere upgrade over the base model.
This is a model of the WS-13E/WS-21 shown at the Changchun airshow
As seen, the compressor has 3 LP and 7 HP compressor stages, with 1LP 1HP turbine stages.
The base WS-13 engine has 4 LP and 8 HP compressor stages, with 1LP 1HP turbine stages,
The RD-33 on the other hand has 4LP and 9 HP compressor stages, with 1LP 1HP turbine stages,
Lastly,
F404 has 3LP and 7HP compressor stages, with 1LP 1HP turbine stages,
F414 has 3LP and 7HP compressor stages, with 1LP 1HP turbine stages,
M88 has 3LP and 6HP compressor stages, with 1LP 1HP turbine stages,
EJ200 has 3LP and 5HP compressor stages, with 1LP 1HP turbine stages.
Thus despite the so called similar origin to the base WS-13 and the RD-33. The WS-21 shares little in common in comparison to it’s predecessors. It’s architecture is completely different, and is far more similar to those found from the west.
The WS-21, is still however an interim engine, the WS-19 greatly surpasses the WS-21 in terms of technology. And is likely on par with latest western iterations of medium class engines.
The J-35A already equips the WS-19, however as a brand new engine, I believe the naval J-35 was more conservative, and the WS-19 has not been readied for the environment at sea.

Ngl the cockpit looks exactly like that one simulator that was on exhibition a while back
looks like this exhibition cockpit is very close to the one of the j35, gaijin could use this exhibition screens to paste them unto the j35s mfds when it comes ingame

These images clearly illustrate the differences in the nozzle convergent flaps between the WS-19 and WS-21 engines.

Is there any good information on the WS-19’s thrust?
Only thing ive found is from a 2022 forum which would suggest ~90KN in afterburner

This was an early indicator—the later evolved WS-21 has already reached a thrust level of 90 kN. Moreover, for confidentiality purposes, the WS-19 shown in this diagram likely used EJ-200 data as a placeholder. Another table later indicated its maximum thrust as 11,000 daN, or 110 kN, though this was not the final value either. The thrust of the currently operational WS-19 has not been publicly disclosed and is generally estimated to be in the range of 110 kN to 120 kN.
