Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection (Part 2)

Just another “bending of the rules” to keep something on a competitive level. We have a plenty of such stretches in the game. From weapons and modules that a county didn’t even had, to flight model nerfs or buffs.

So I was looking into the AL-37FU and comparing it to the AL-31FP, and… It kind of looks like they have different deflection angles??? I’m not sure.

You mean non-existent FUs. But it’s a bit simpler. Both Su-37 and Su-30SM have same engines and same nozzles, but Su-30SM have nozzles slightly rotated so their deflection angles resemble \ / while Su-37 didn’t had that and its angles look like | |

That’s why I was looking into it lmao.

How peculiar.-

It was done to get a pseudo 3D TVC. Both engines deflect independently, so you can get combined vector to be almost at any direction with this setup

At least the way the nozzle fits into the nacelle is different. 31FP and 41F1S have rounded gimbals

It could be just either early version of the nozzles, because it was pretty much in a prototype\technology demonstrator version or it could be just a protective cover for the moving part of the nozzle that later was removed for one or the other reason.

Andrei Foiman’s book doesn’t call it al31fp, just calls it prototype al31f with thrust vectoring. I usually call it fp for simplicities sake but it’s different from fp

Would make sense. AL-31FP is a name for a serial production engine.

Funny how some of the mentioned maneuverability and aerobatics Su-30SM struggles to do in-game even at min fuel.

Also conclusive evidence that 710 had al4f1s engines if anyone still doubted (at the time it still wasn’t called al41f1s yet)

Su-35 18400 kg (finally have 2 good secondary sources on this)

@sudo_su1 have you made a bug report on su-33 wrong vne/top speed? I recall you doing some reports for some of the flankers
Also looks like su-33 is underweight by around a ton… might have to do a bug report to get that fixed. Su-33 might barely be flyable after that, emergency mode on its engines ain’t saving that

F-15 in game flies on 102% trim it can use only for <5 min

It will be still hard carried by the missile kit anyway. If flankers had better energy retention, having worse TWR wouldn’t mean as much imo, but with them bleeding majority of the speed after a single turn with that enormous amount of drag makes them live of engine thrust.

Overheating exists in game. You can make report if it’s don’t overheat after 7 min and you think it’s wrong.

102 trim and V-max is different things IIRC

Has this been patched? Haven’t played the dev server for 3 days

Why does the SU30 stop responding to any control inputs at low speed? It actually freezes

Is there a way to stop it happening? Feels lke a bug
