I honestly don’t know when it comes down to details. It’s better to ask the Technical Moderators through a private message in this case. You can find all the teams and the areas they handle listed here: (Who is who and Reporting Procedure). If you don’t get an answer within a few days you can add more moderators from the list to the original message instead of sending a new message (that way you preserve the date of the message and it doesn’t look like a new request), adding one of the moderators to the message every 2-3 days or so until you get an answer.
Please do not to add the seniors until you have tried all other regular moderators, the Seniors likely won’t answer unless they are added and pinged by the regular moderators but if you’ve added all the regular moderators with no answer then you can add the seniors.
Obviously, Gaijin has a blatant double standard regarding the sources they accept. On the Dev Server, the weight of the WS-10B is pulled from Jane’s—the alleged 1795 kg figure—yet the weight, thrust, and thrust-to-weight ratio data on that very same chart don’t correlate at all. It’s essentially just a bunch of fabricated numbers.
The developers can use Jane’s as a source, but if a player tries to submit an issue based on that same data, anyone who has actually tried to file a report knows exactly how that ends. 😅
I have also noticed areas that require improvement regarding the thrust envelope of the WS‑10B engine:
Based on the latest data from Test Server .21 on March 3 and the flight envelope of the WS‑10B engine, the ram thrust coefficient of the engine is lower than that of the WS‑10A at all altitude ranges, resulting in a significant difference in the growth rate of the thrust curve compared with the WS‑10A.I sincerely hope the game developers will check the relevant coefficients and adjust the thrust curve appropriately.Currently, in top‑tier fighter matches, the J‑15T ranks last in acceleration performance at high altitude and high speed, and I hope this issue can be taken seriously.
This problem is specifically demonstrated at an altitude of 7,000 meters:
At 0 km/h:Dual WS‑10B thrust: 11,750 kgfDual WS‑10A thrust: 10,447 kgfDifference: 1,303 kgf
At 400 km/h:Dual WS‑10B thrust: 11,915 kgfDual WS‑10A thrust: 10,968 kgfDifference: 947 kgf
The dual WS‑10B gains 165 kgf of thrust from the ram effect at this speed range, while the dual WS‑10A gains 521 kgf from the ram effect.Despite having higher static thrust and being more technologically advanced, the WS‑10B even exhibits lower ram efficiency than its predecessor, the WS‑10A.
This may seem insignificant, but the gap will be further widened at higher speeds, even in the supersonic range, resulting in only a small improvement of the WS‑10B over the WS‑10A at high altitude and high speed.This issue is equally evident at other altitudes and speeds, resulting in low actual usable thrust from the WS‑10B.
According to the developers’ usual practice, thrust curves are usually created by scaling up the previous model proportionally based on the static thrust values shown in the in‑game interface.In other words, the thrust curve coefficients of the WS‑10B should be consistent with those of the existing WS‑10A in the game at all altitudes and speeds.However, in the latest test server, the coefficient of the WS‑10B is significantly lower than that of the WS‑10A, leading to insufficient thrust at high altitude and high speed.Currently, the climb and acceleration characteristics of the J‑15T in these altitude and speed ranges are far below the average level of top‑tier aircraft.
I sincerely hope the game developers will attach importance to this issue.
At 7,000 meters, it is clear from the curve that the gap between the two is narrowest at 400 km/h. This lower ram ratio will carry over to higher speeds, making the actual performance improvement of the WS‑10B disproportionate to its static thrust increase.This problem is equally obvious at other altitudes and speeds.
Just because the number is in a Jane’s publication does not mean Jane’s was used as a source for the game. That’s not how evidence works.
Also, WS-10B has an in-game static* thrust to weight of 7.655:1, and an in-flight thrust to weight of 8.635 - 9.136:1.
Granted, this doesn’t matter because engine mass on statcards don’t impact the empty mass of aircraft in-game.
Ah, Alvisra, don’t tell me that Gaijin employees just randomly pulled the number 1795 kg out of thin air, and it just so happens to be exactly the same as the data from Jane’s.
Also, please don’t selectively report only the in-flight thrust-to-weight ratio of the WS-10B. Could you tell me what the ground thrust-to-weight ratio and in-flight thrust-to-weight ratio are for the AL-31FN3, AL-41F, and WS-10A? In the game, the weight of the AL-31/41 series engines is all around the 1500 kg mark, yet only the WS-10B weighs nearly 1800 kg. The improved AL-41F has almost the same weight as the AL-31 series, but the improved WS-10B has a drastically different weight from the WS-10A?
I certainly don’t mind Gaijin making reasonable estimates—what if the actual thrust-to-weight ratio of the WS-10B isn’t as high as Jane’s claims? But what’s with 1795 kg? Two engines add up to nearly 600 kg of extra weight! If we subtract those 600 kg from the in-game J-15T, its weight would be 17.7 tons, which is extremely close to real-world data.
Even if we set that aside—if Gaijin’s calculations aren’t that logical, why not just give it an average thrust-to-weight ratio? Setting it to around 8.1, similar to the AL-31FN3, would also make the WS-10B much lighter—1667 kg. What’s the meaning of 7.5?
Putting all these factors together with Gaijin’s selective use of sources, I can only reach a conclusion I really hate to say: Gaijin is deliberately nerfing the J-15T so that it won’t outperform the Su-30SM2. No, I’m not even asking for it to be “stronger”—I just want it to be “comparable”. Yet on the current test server, the J-15T is outclassed in every aspect by the Su-30SM2, with the only advantage being an extra MAWS. Is that worth a BR of 14.7? Right now, the J-15T is just a J-11B with two more PL-12s (the PL-12A has seen no performance changes to its propulsion besides adding GNSS), the J-10C’s radar, and half the countermeasure flares! A 13.7 BR plane with these minor tweaks bumped up to 14.7? I honestly don’t know whether to call Gaijin incompetent or intentionally malicious.
Yes. That’s exactly what I mean: We all know this kind of data is classified, so Gaijin has no choice but to use less precise sources for their in-game modeling. I certainly have no objection to Gaijin making reasonable estimates.
But why does Gaijin only cherry-pick certain data? If they’re going to use Jane’s data, then stick to it in full. What’s the point of intentionally using only parts of it?
Alternatively, maybe the figure of 8.8 is unrealistic. Even then, Gaijin could easily have chosen a value slightly higher than that of the WS-10A, or at the very least, a thrust-to-weight ratio similar to the AL-31FN3. That would be a normal, realistic estimation—balancing against real-world equivalents.
Instead, they’ve settled on a thrust-to-weight ratio of just 7.5 for the WS-10B, which looks like it was picked based on personal preference (or other hidden motives).
It’s not my job to prove Jane’s is right — it’s Gaijin’s.
Or rather, whether Jane’s is correct doesn’t even matter.
What matters is that they are cherry-picking data from Jane’s.
Here’s my take: I can totally tolerate Gaijin using inaccurate data —
but they have to be fair about it!
Why does Gaijin only pick the parts that hurt performance,
and never the parts that boost it?
Yes, I agree. OBVIOUSLY 1795kg is wrong(compared to the 8.8 thrust-to-weight ratio). I don’t know whether Gaijin is smearing WS10B DELIBERATELY or not. The fact is that a tremendous number of Chinese players are feeling insulted .
Gaijin should give us a fair result, the weight of WS-10B must be reduced!
Gaijin always doing this.There are three monsters in 14.7 and now they still want to add a fighter like F/A18 which is ‘reality’ that those unreal monsters in 14.7.This unfair to all players who do not have those monsters fighter at all.Not only to the J15T.I am done for it.They are really testing my patient.This is last one,make WS10B right so that J15T and J10C can have a fight with that three monsters in game or lost a player.I know gaijin don’t care about a single player Ieave or stay so am I,I don’t care about what they thinking.I want a result.
