After it was discovered that the Mig-29 suffered from an asymmetric roll at high angles of attack after it killed several VVS pilots and a OKB test pilot. The VVS ordered the manufacturer to reduce the angle of attack to 21-22 degrees with no combat override.
Mikoyan corrected issue by first extending the rudder chords and AOA was increased to 24 degrees. This is the manual @FeetPics & @kizvy are trying to lump every Mig-29 in-game together in. They are using flight manuals of aircraft that have been completely phased out.
They are pathetic and it shows these dudes have no interest in achieving historical models.
See the alpha at 24… This is the initial production 9.12. They are using initial production MiG-29 manual that were completely phased out (first 100 units.)
Anyway, MiG then added a vortex generator to the nose and removed the ventral fins.
The SOS-3M angle of attack limiter was increased to 26 degrees and combat override (17kg of stick pressure) was reestablished.
All MiG-29’s in game are under performing and capped at 22 degree angle of attack. No initial production 9.12 are in-game but flight model is nerfed like them.
Oh look…the installed thrust in game actually matches up with bookept values. It is almost like the entire aerodynamics manual for the plane is available and that appears to be what Gaijin has modeled it based off of.
It’s crazy that the manual doesn’t show an installed thrust value of 16,600kg total (8300kg/engine) that ZiggyGPT ends up spitting out.
@Ziggy1989 How is MIG-29 ever physically supposed to reach it’s max installed AND static thrust on the ground? It cannot even use it’s main intakes unless the landing gear is hidden
This one also show basically the same thing. Notice how AoA limit has big L shape drop off?
It should also be noted that the G limitation is not something that is hard-coded into the flight system…but rather there is monitoring equipment and the pilot will get in trouble for exceeding it. It’s no different than F-14 or F-15 having G limits.
And once again we are just going to ignore installed thrust being correct. Why does aerodynamics manual document show static installed thrust of less the 15,000kgf when you say it should be 16,600kgf at a minimum?
I do not understand your questions. Take-off thrust is not the engines maximum possible thrust installed. It is simply the manufacture’s baseline. The engines actually produce more but the lowest thrust rating that all engines of the same type can reliably produce together is selected by the manufacturer and placed in the operation manual.
This is to create a safety margin when the aircraft is conducting the most critical phase of manned flight, taking off. This is a industry standard the FAA, DoD etc. has adopted.
RD-33’s Static Thrust @ Sea, Standard day (take-off thrust) = 8,300kgf × 2 = 16,600kgf
This is how the aircraft has a legendary thrust to weight.
Thrust-to-Weight Ratio (TWR)
Take-off Thrust / Gross Weight = 16,600kgf / 14,454 kg ≈ 1.15
Yes, with a gross weight @ 14,454 kg (full internal fuel) for the MiG-29G this is consistent with reality.
It just take-off burns a little bit of fuel and its 9G ready with a thrust to weight ratio of 1:1 at take-off.
"When the engines are operating in the “Full afterburner mode during takeoff. (H=O, V=0), the thrust-to-weight ratio of the aircraft is 1.14.”

The longer it stays airborne the higher that thrust to weight ratio increases. It starts off with a 1.14 thrust to weight ratio…
Its combats thrust to weight is monstrous at 50% internal fuel, still able to be armed with missiles & has full 9G capability.
You highlighted that the MiG-29 It is a true 9G fighter almost its entire flight envelope once it burns of some of its full internal fuel after take-off.
hi, could u point me in the direction of this (i’m assuming nva mig29a? or something similar) manual if it’s available to be shared? thanks
hi copilot could you explain to me the differences between available power and calculated thrust and specifically how it is handled in russian aerodynamic conventions? thanks
well looks like the suggestion i wrote last week for the #154 MiG-35D didn’t get accepted to the forum, will try to potentially submit another one sometime in the future
