I wasn’t aware of that, perhaps a mass issue then? a greater mass with equal drag and thrust should reach equal speed just slower to get to it. It’s also possibly a mach limit of the air frame.
That’s cause the mig-29 is air frame limited not drag limited.
Mig-29 normal can go over 1600 kph ias irl as its engines does not care, but after 1500 kph ias it experienced severe wing buffering during testing. so it’s limited to 1500 kph ias in service
I know, but in-game SMT has lower rip speed than other MiGs
That’s surprising, cause irl it has the same limitation of 1500 kph on the deck/ias.
Maybe bug reportable?
The extra mass will also make a tiny increase in extra AoA for archieving the same lift, so it will make drag a tiny tiny bit worse in a straight line.
Probably not enough to be relevant in this context though
Every MiG-29 FM reach rip speed when passing 1575kph IAS. They are all the same in that regard
Same as the SU-27, both are noticeably overperforming in top speed at low altitude. I think its because of how gaijin tries to match E-M curves by adjusting engine power/drag values while having a fundamentally wrong FM to begin with.
Wait, I am retarded, VNE is the same, max speed is different
1518 for SMT and 1545 for 9.13 at the deck
welcome to the club, buddy.
It low k makes sense for su-27, as it’s a 1.1x multiplier instead of 1.05 multiplier for top speed because it’s not the wings buffet or anything, it’s cause compression of the rudders increase by 65% (basically the plane can’t yaw as good)
So it shouldn’t rip its wings at 1400 kph.
Which is why gaijin set the rip speed much higher than its in service top speed limit
I wonder how it affects M2 airframes, since they have larger and thicker tails (they are still missing fuel tanks in them aren’t they?)
I got that info from the su-30sm aerodynamics book, so it would probably apply similarly to the other su-30s.
I lied It’s actually 60 percent not 65
truke
In game, I tested the top speeds between the 9.12, 9.13, SMT and 29M since they all have different spines.
I used 108% afterburner between them because at 110% the 9.12 will just rip the wings at over 1575 kph IAS. Clean configuration and min fuel.
MiG-29 9.12 @ 100m, 108% afterburner
Top speed = 1545 kph IAS
Thrust per engine = ±11642 kgf
Drag = ±23265 kgf
Fuel = 991kg
MiG-29 9.13 @ 100m, 108% afterburner
Top speed = 1527 kph IAS
Thrust per engine = ±11610 kgf
Drag = ±23230 kgf
Fuel = 1036 kg
Note:
MiG-29 9.13 at 1545 kph IAS has ±23800 kgf which is already higher than the 9.12 at the same speed, to match that speed, it needs to be at around 108.5% afterburner, 109% is already a bit too much.
MiG-29 SMT @ 100m, 108% afterburner
Top speed = 1498 kph IAS
Thrust per engine = ±11542 kgf
Drag = ±23090 kgf
Fuel = 1305 kg
Note:
The SMT at maximum 110% afterburner will achieve 1546 kph IAS, which is about the same the 9.12 can do at just 108% afterburner. At this speed the SMT has around 24500 kgf of drag.
Bonus:
The MiG-29M at 105% afterburner will match the 1545kph IAS top speed, with a drag of around 23620 kgf. So the MiG-29M is the draggiest FM between them all, but the engines will easily overpower that limitation.
Su-30SM has different tail from MK2 and M2, that’s why I am curious. This compression is due to tail deformation under air pressure, so tail of different dimensions will react differently
What redesigned LERX and tail section does to a mf. We will not mention the fact that frontal part of the fuselage of MiG-29M was welded to reduce the amount of drag from rivets
It also doesn’t have the refueling probe, that alone would make the drag better than the SMT, but they are all overperforming either way
Are they? Considering gaijin modifier of 1.05?
Realistically, they would only achieve around 1500kph IAS at most, I think. Regardless of modifier, it seems like they have double standards.
By the way, the 1.05 modifier means that the jet rips at 1575kph which it does in game. But that doesnt mean that it should achieve that in a level flight, only in a dive
Gaijin would never…
But jokes aside there are “more equal than others” examples pretty much in every tech tree, so this doesn’t really bother me
