LOOL. Chinese engine tech have surpassed Russians. service life and MTBO exceed any Russian engine with a fair margin. Chinese also solved the chronic problem of black smoke, what Russians have been struggling ever since. Chinese precision manufacturing is miles ahead. not even a comparison. civil industry development have always an impact on your defense sector.

WS-10C performance in terms of thrust , inlet turbine temperature , fuel consumption and with digit control system is exceed all Russian engines. this is confirmed by deputy chief designer of J-20 during Zhuhai Air show 2021.

as gelgoog mentioned, The Russians have been having trouble manufacturing the engine reliably enough. coz their military industrial complex assembly lines still have soviet era elements. for example PD-14 their latest engine still Assemble on PS-90 assembly line.

I don’t think China has surpassed Russia in engines yet, but it probably reached parity. Unless you have numbers to show otherwise.

The latest Russian fighter engine to reach operational service and be qualified is AL-41F1S (117S) which has MTBO of 1,000 hours and life of 4,000 hours, while the figures from WS-10A from what I read is 1,200 hours MTBO and 2,000 hours life. That said AL-41F1S only finish trials in 2018 and WS-10A was in widespread use in 2012 or 2013.

AL-31FM2 from Salyut that powered initial production J-20 is similar to AL-41F1S. They both produce 142 kN thrust and have 4,000 hour life.

What are the numbers for the current WS-10C?

The most advanced WS-10 variants have reached the 140 kn range now. And given changes in service requirements for Chinese engines starting around the mid 2010s, it's probably got better service life than Russian engines now. Supposedly that change in servicing requirements was one of the reasons for the delays on a number of engine projects, including the WS-15 and WS-20.

I think the WS-10C is at least 142 kN and possibly 147 kN. They are also better with burn rate than the engine they replaced according to that J-20 video (program director?)

Also, I doubt Zhuhai air show will provide real numbers for WS-10C that J-20 uses. Both J-20 and J-16 are likely to use the highest spec'd WS-10.

you know nothing about current Chinese engines. so please sit down.

Instead of a rude dismissal, why don’t you explain using some numbers and sources? I’m admittedly not terribly familiar with Chinese engine developments, so show me then, instead of replying like an ass.

Whoa, slow down.
You seem to be under the impression that we have access to accurate numbers and indisuptable sources.
In reality, those are hard to come by, if not impossible to come by.


In the public space, PLA watching arises from people with experience who have tracked noises and rumours over years (or even decade/s) and are able to come up with educated estimates.

So for people new to PLA watching, it usually comes down to being able to recognize people who have more experience and with reasonable logic and common sense and good track records, and to accept them as more of an authority.

There’s nothing in the open source? Because I’m not familiar with Chinese language sources on these topics.

If you think there’s a serious risk for OPSEC violation on an English forum on the PLAAF, that would be bizarre indeed.

If he provides Chinese language sources, you can read them? If yes, why don’t you look for them yourself
