Most of Gaijin’s (mainly older, before 4th gen) FMs have an inherent need to overperform because the thrust output at AOA isn’t constant. They like to compensate with drag so the bleed rate is too high, and the plane feels nasty to fly.
If intake losses don’t increase at higher speeds then it also creates a problem they have to fix with drag.
Thrust reduction* by >10% at 14 AOA for shock cone intakes
Thrust loss is combined from inlet losses and stalling of turbulent air on the compressor so the problem is worse than it shows on that chart but Gaijin doesn’t model this issue. Instead - fighters like the F-4 are designed to achieve the correct negative and positive excess power based on AoA and this is fairly close. It only really affects some fighters like the Russian ones who do not have explicit SEP charts included. EM Diagrams have these as standard but are only used by the west.
That was what I had in mind, and I think about this largely in relation to MiG-21 and MiG-23 (mostly 21) because their FM “feels” wrong.
Mainly on low G, they lose far too much speed, kind of like MiG-29 FM.
Those lists are not comprehensive limitations of what can be used, only advertisements for specific ordnances. It says nothing of prohibiting the use of other stuff not on the list.
So nothing on double racks of R-77, but RVV-SD might still be used?
Also KH-29T is probably generalised for TD and TE I guess cause that thing is actually crap, not likely a modern jet’s choice.
I wish people spoke more about the in game usage and characteristics of the aircraft in these threads rather than so much the theoretical additions and things like that. I’d like to talk about the Su-27’s gameplay but not much discussion there
This thread is not exclusive to gameplay tho, i would say it’s not even one of the most important issues discussed here, it’s a Lot more focused on the history of the flanker and its variants and i believe its main purpose is to help making the plane as accurate as possible ingame… ppl are talking more about the 30sm NOW cuz it got leaked and it’s the next top tier addition for Russia.
Imo the su-27 is the best 13.0 by far, 27ERs are monsters and you get 6 of them while f15s get only 4 sparrows, although the f4 ice gets amraams the airframe sucks. Against other ranks i personally don’t think it’s that crap considering that in downtiers you can absolute obliterate the enemy team, but it would be nice to get some decompression, uptiers against f15C are acceptable but fighting stuff like typhoons is kinda sad, not as bad as the mig29G because you have much more stuff but it’s still sad.
I have mixed feelings about it, particularly on the sim side of things.
A lot of jets were lowered to 13.0 recently, which has made the 12.0-13.0 BR range in sim feel absolutely infested with 4th gen jets at this point. You see the occaisional harrier or F-4F KWS LV, but everyone is flying around in MiG-29/F-14/F-15/F-16/Gripen/M2K/M4K now. I the past, when the F-15 and M2K were the “oppressive” planes in the BR range, I wouldve said the Su-27 had no place there and would have rathered seen the M2K/F-15 raised to 13.3, but now that 13.0 has seemingly become the defacto “4th gen without ARH” BR, I think the Su-27/J-11 likely deserves to be dropped down.
On the flipside tho, the R-27ER really is a tremendously powerful missile, and is only matched/exceeded by ARH’s, so it might be too much for the BR range when paired with a good FM and HMD.
On a bit of a selfish note, I do wanna see them dropped to 13.0, or for there to be a 12.3-13.3 BR brqcket in sim sometimes so i have an excuse to run my J-11, cuz i got a nice camo for it :3
