It’s becoming a modus operandi now… It gives a mediocre (as in WT) Chinese jet, cause an uproar among the Chinese TT players, they in turn ask for a better performance (flight model, engine, armament, etc.), it pretends to listen to them, rolls out some modifications for the jet, and make the post-mod version even worse in terms of performance.

With the introduction of WS-10B, the J-10C’s empty weight has gained from 8820kg to 9045kg.
So there is an 225kg difference between AL-31FN S3 and WS-10B, it seems that Gaijin has not used dry weight for the engine.

I have no idea where Gaijin got the weight data for the WS-10B from.

According to this post, rn WS-10B is 1795kg ingame while WS-10A is apparently lighter at 1520kg.
Idk, can anyone check the datamines to see if that is true?

The engine mass is not assigned as a separate value and it’s just a text entry; the aircraft’s empty weight is assigned as an integrated whole.

I see, but it’s clear that WS-10B is heavier by 225kg compared to AL-31 as seen by the empty weight increase

Sea level: Buff since .20.


9000 meters:

But it does appear to be a change caused by the higher weight of the ws10b

I just have no idea where Gaijin got the the higher weight of the ws10b.

They may have included all subsystems in ws10b’ s dry weight

This is ws10’s wiki info, maybe it’s their main source

They did not do this for any other engine btw, only for WS-10B did they include all of the subsystems.

However, there actually are a few official publications indicating that under the same standards, the WS-10A has the same weight with the AL-31F. A simple calculation: 13200 / 7.5 = 1760 kg, which equals 12500 / 7.1, meaning that even if the Wiki data were correct, the WS-10B would only be about 30 kg heavier than the AL-31F, not 270 kg.

From what I heard, WS-10B has a T/W of around ~8

Maybe you could try submitting this calculation as an issue, I think our best chance would be to find sources that mention the T/W of the WS-10B.

China seems prefer to use total weight to calculate T/W, but not clean weight
