WS-10A roughly matches the Russian engine thrust and curve. It is not better.
WS-10A is a domestically produced engine with the goal of performing equally as well as the Russian engine, perhaps with improvements to lifespan, maintenance, and fuel consumption courtesy of the new full authority digital engine control unit.
It is the WS-10B that improves the thrust from the ~125kN static as shown to ~144kN as stated by Chinese media.
WS-10A has 89.17 KN thrust, AL-31F has 76.49 KN (Dry), WS-10A Wet has 132 KN, while AL-31F has 122.6 KN.
I think WS-10A better than AL-31F, No?
Does this include intake losses?
The graph above is WS-10A
this pic is said to be early WS-10, which has some problems and it wasn’t accepted, later improved WS-10A was accepted for J-11B. and Later improved WS-10A reached 13200KN.
but the curve is referable, showing the engine’s character
As I said the WS-10 thrust curve is similar to, and not more than the Russian engines until the WS-10B. Comparing them all solely to early non FADEC Russian engines is not worthwhile.
I made a mistake, it is WS-10A. but the test standard of the engine, including USSR, is in about 0.6Ma, so it is 13200N, and this AL-31F’s envelope also matches this, 12500N in about 0.6Ma. and seems WS-10A behaves better in high altitude from the envelope.
Long story short, we want the J-11B block 02 with the WS-10A but let’s not over-estimate the thrust increase here. Manage the expectations.
a little improvement is still improvement imo, though not a jump like PW229.
The j11 and the j11a will already happily rip their own wings off so it’s not like it needs that much more thrust.
It is better in thrust, but worse in resource and weight
shouldn’t it be lighter than AL-31F? according to this
No, and you’re showing thrust, not weight.
Looks to me it’s heavier
Also, china seems really behind on engines compared to Russia or USA back like 20 years ago
This is not the entire picture.
WS-10 family has evolved drastically in terms of reliability and thrust.
So it is not fair to say that current Chinese engines are bad.
Any slight improvement is an improvement.
China had poor development until the 70s-80s, they are still playing catch up with engine development.
Such is the case, but there has been both a development and a desire to improve.
If you don’t have any source or substance from which to discuss the engines utilized by the J-11 family please refrain from posting nonsense philosophy
