That’s fair, which is why I’m asking if some of the more experienced watchers can maybe provide some numbers on MTBO, static thrust, etc. and I provided some contemporary values for Russian engines as a point of comparison. I’m not looking for classified processes or methods.
Chinese Engine Development

- Start date
I'm sorry, but those sort of numbers would indeed be considered relatively classified and most of what we have are educated guesses and extrapolations from out of date numbers given from the past.
That's what I meant by "you seem to be under the impression that we have access to accurate numbers and indisputable sources".
If it was as simple as providing a list of numbers like thrust, MTBO, then everyone would have already done so.
Dear Santa, please tell us you do!
cannot tolerate a person, who is actually exaggerating Russian tech in 2022. LAMOOO
so you want source. fine
during Zhuhai Air show 2021. deputy chief designer of J-20 officially acknowledged, WS-10C performance exceed all Russian machines we have used before. in terms of thrust , inlet turbine temperature , fuel consumption and service life.
how Chinese surpassed Russians despite very late start .. coz they learned from west. civil high tech industries development and progress have always an impact on your defense sector. USSR/Russia both failed in this sector. Russia still struggling in precision manufacturing.
Russians are still unable to solve the chronic problem of black smoke. this is latest SU-57 during test flight powered by AL-41 engine. heavy fuel consumption machine with low service life. look at the black smoke
not even a single Chinese engine emit black smoke. it means chamber and core machine of Chinese engines are far better than any Russian engine.
WS-15 is very close to enter in small scale production stage. this engine will put China into elite group of aero engine makers globally.
Russian jet engines fell behind because of the lost decade in the 1990s. If you look at the specs of the Saturn AL-41F for the Soviet MiG Project 1.44 they are not behind those in the US ATF. The Soviets had times when they were behind in jet engine technology, and times when they were slightly ahead in some aspects, more times when they were behind, but in the late Brezhnev era they were pretty much either to par or the Soviets had a slight edge. The main issue the Soviets had was lack of modern FADEC.
Seems like an ancient Russian curse. Even today, Russian engines are as good or perhaps even a bit better (at the leading edge) than Chinese counter-parts. Where Russia falls far behind is in avionics/radars etc, where China is now better.
In the cold war era, Russians were not interested in improving their engine's service life because they thought fighters were consumables in a war with the West. After USSR's collapse, Russian military industries always face lack of money. Meanwhile Chinese engineers are studying western advanced concept.
I've seen J20 emit smoke intermittently. Its kinda hazy and not as bad as RD-33. Due to the low quality video given, i'm not sure if it's the AL-31 batch or WS-10 batch.
While China's aero engines improved by leaps and bounds, perhaps due to advancement in microelectronics (FADEC) and material science, i would still not say the Chinese surpassed the Russians. The Soviet left behind many interesting stuff. The NK-12 turboprop is still most powerful in the world. Russia has produced more than 1000 PS-90 engines. Theres still plenty of interesting stuff at Motor Sich (which is why China is keen on). Also, lets not forget the Soviet started to work on Al-41 (not 117S) back in the 80s.
Lately we've seen China come out with a few new Aero engines, namely the AEP500 and AES100 etc. I can say China is almost there, but not quite there yet.
Can we get some corroboration from well-read people here whether posts like these are accurate or even close to accurate? Or at least if this particular poster has been known to be reliable enough that we can take his word for granted?
I don't know who we can rely on and who is just exaggerating or even just making stuff up. It would be great if there was a page which should moderator approved individuals who are considered to be at the top in terms of objectivity, reliability, so on.
