Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection

At what range/altitude/speed do people usually fire the R-27ER if they plan to loft it and drop lock until its close to the target? To target AMRAAM carriers specifically

They fire around 6000m or so and just pick target near cluster of jets. It will probably be close enough to someone to relock. This only works in RB because of clustered enemies.

With 27SM air RB: take low fuel (~19min, more than enough for whole match), climb to at least around 7500m without dropping below mach 1, fire at around 60-55km

just fly below 60m and punish anyone who flies above 60m with the r27er, there are situations where doing bvr with the r27er would be acceptable, but most of the time it is better to be aggressive, given the speed the r27er has anyone flying high within a 7km radius will not be able to avoid dying so easily

I already have flown it this way, I’m trying to learn what its capable of.

For what it’s worth I have been doing additional testing on Su-27 flight model…and while the turn rate is buffed at medium speeds and is a welcome change…it’s also still underperforming at low speeds.

It still has the issue where there is too much induced drag at higher AoAs that cause it to slow down and pancake. Just cross referencing Statshark L/D diagrams vs predicted ones shows that drag vs AoA is too high and that Lift vs AoA is also too high.

It’s Oswald Efficiency is stil in the .5s if I recall correctly. There is a study that predicts OE value of around .7…this in and of itself isn’t really any kind of indicator…but also the same study predicts the F-4 Phantom having an OE value of .7 and the wings OE value in WarThunder is .685 which is very close.

That doesn’t mean the current value needs to be increased to .70…rather that the entire flight model is just extremely cobbled together and to make it accurate would have to be substantially changed.

OE continuously changes with AoA in real life thought… do you have a picture of that study? Because Cd and Cl do not have always the same proportion.

With this I completely agree thought, this FM is just a mess.

R24R arrives at target fastert sub 10-15km, especially back then. Then someone forgot it had more range IF… IF it even decided to track. For long range shots, like 1 out of 3 would track and 1 out of 4 would track whatz you actually want. I flew plenty of MLD, F14 and F-4J… MLD was most broken out of them all and still best for air RB meta even when F14 came.

The issues you speak of regarding the AIM-7’s were not true of the AIM-7F. I had no issues with that model whatsoever. I flew the MiG-23M/MLD as well as the F-14 and F-4J quite a bit back then. What you are saying is extremely biased against the AIM-7 for seemingly personal reasons. Quit playing the victim.

This is the best study I can find that provides simulated lift/drag diagrams for Su-35 type flight model. Lift/Drag diagrams in this study can be cross referenced with lift/drag diagrams from Statshark.

This is the study that people are citing for the OE number for the Flanker being incorrect.

Finely got around to play the su27
Why doesn’t the Datalink of the r27er/r27er show on the radar anymore pretty sure it did before?

Is that a bug or intended?

I hope you were kidding

I wonder, when theyre going to add the su27sm3, are they going to give it 14 missiles? because we currently get the su27sm with the erroneous double r77 pylons, and the sm3 has an extra wing pylon im pretty sure.

I really want to get some modification of Su-30 for a good radar and R-77-1

That’s going to be the Su-30SM at this point. R-77-1 will come separately more than likely. If they can fix the supersonic drag issues, the R-77 might be good enough until the next upgrade of ARH’s.

I would also like to reduce the height of the multipath to 20m

Is the R-77 much worse at flying now than IRL?

You have no clue what you are talking about the MiG-23M at the time would smoke F-5E’s in a dogfight. Prior to it coming to the game there was no good way to flare the AIM-9J and it was much harder to dodge. A 20G missile then was equivalent to a 30G missile now. They had no fuse delay.

The reason the MLD was added was because Russia was getting beaten so hard into the ground they thought it was necessary. Your recollection of that history is terrible. The MiG-23M performed poorly because it had few countermeasures and people didn’t really know how to play it. It out-rated the F-5E and smoked it in the one circle after the “fix” to the weight and thrust.

All this “well this happened” in the history of the game is irrelevant anyway - the Su-27SM should be a historically correct aircraft without double pylons and if they are going to give it the enhanced engines they should call it by the correct name and amend the other issues. This isn’t a “balancing” issue or discussion. This is purely a discussion about the Su-27.

I remember enjoying the old flogger back in the day, i believe i played more matches with the 23M than with the MLD

Yes, because the drag mechanic in game slaughters the missile’s performance at launch. Yes it has grid-fins. Yes it’s a very drag-y missile. But at supersonic speeds, the drag coefficient shouldn’t be as strong as it is. The drag should kick in more strongly once it’s in trans-sonic and then subsonic speeds.

IIRC, the missile should have about 2.5km more effective range. Right now, it’s not worth launching at most targets past 17.5km.
