Yeah I saw somewhere gaijin models usually anywhere from 15 to 20% loss. Which if it is the case this engine is sitting a little under 20% loss.

Flankers are 2% in game acutally
Smt is sitting closer to 17% after doing the math.
Interesting the flankers are that low.

Artificial nerf, otherwise they would have bonkers acceleration, Especially in the MiG-29 Astryaka.

Well the F-15E’s 229s are having about 16% channel loss as well so it seems along the avg.
@kitsune_qq What numbers do you have for the AL-31F engines? I am seeing about a 12% loss for power with my math.
Must be 2% by flight manual.
Idk whats in game
I also found an article that states that Mig 29SMT should have RD-33 series 3 engines.
The engines thrust are correct.
The intake is closed at static speed, so of course it’ll be higher static.
@Zyranovos
There is no artificial nerf.
SMT’s engines produce over 11,000kgf at speed.
@Neothe1
SMT already has RD-33 Series 3 engines in-game.
Correct me if I am wrong, I read the War Thunder Wiki witch states that at stationary, I interpret this as take off, it has 6816kgf, while based on this article https://www.airforce-technology.com/projects/mig-29smt-fulcrum-multirole-fighter-aircraft/?cf-view, it has 8,300kgf at take off. I don’t know how that translates to at speed which you stated at 11,000kgf.
Perhaps if it has 8,300kgf at take off, then at speed could be higher. But I might be wrong on that one.
How do you guys calculate this channel loss, what formulas do you use?
RD-33 has an uninstalled static thrust of 8300kgf.
Installed it’ll be reduced.
Installed into an aircraft with an integral anti-FOD device it’ll reduce further.
Static thrust doesn’t matter that much, what matters more is thrust above 600kph, of which RD-33 grows substantially.

Thanks for the info now I know that the 8300kgf is on an uninstalled engine.

Although it is not only the engine but it is also the problem of the flight model, it is horrible, the flight model of the mig 29 SMT is very bad.
It’s channel loss, same has been reported about JF-17, where the stated thrust in game (stat card) doesn’t represent thrust in actual flight. I am pretty sure it does more than 7t of thrust but it is just what the stat card says, I know for sure the JF17’s RD93 (akaRD33 with mods) does around 10t at correct conditions even the stat card is almost the same as RD33.

It is true that the actual thrust of an engine in an airplane can be reduced by aerodynamic losses, such as friction within the intake ducts and the physical constraints of the fuselage design. However, the standard should be applied consistently across all aircraft in the game.
Comparison to other aircraft such as -
The F-16 engine in War Thunder (General Electric F110-GE-100) is reportedly almost at its maximum nominal thrust with hardly any apparent losses. This creates an inconsistency if the MiG-
29 SMT is penalized with a much higher percentage of losses not applied to other aircraft, they only apply it to the mig 29 when we have things like the F15 Strike Eagle with almost all of its real thrust.
F15 also has channel loss, just smaller. The stat card isn’t completely true, I know as a fact that it can do more (RD33). I tried with RD-93 and it does near 11t actually, instead of less than 7. There is this thing which can show u the thrust during flight, can’t remember the name of it.
For me, they were based on a NATO test of the Mig 29 that carried “THE 3 FUEL TANKS” AND they compared the AoA with the “Maxima” load.
Which F-16 has GE-100s?
The F-15E is missing 20% thrust for channel loss. the 29SMT is around 19%.
