Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection (Part 1)

We have Mach 2.0 quoted by the manufacturer.

We have mach 2.35 quoted by the germans.

We have Mach 2.3 to stop derailing and trying to make the typhoon look worse for no reason. We have stuff explicitly saying it does Mach 2.3 now stop it

Not trying to make the Typhoon worse. Confused why the manufacturer would play down the top speed.

Su-30SM(E) should be 1.75 mach, as stated by rosoboronexoirt
So, near to 1.8 wing rip
Reports not accepted yet

I wonder if I understand this right. The Su-30SM has a similar turn performance to an F-15E. With that said, F-15E beats it at time to speed lol

I wonder if statshark was updated with new data

The problem is the Su-30SM has thrust vectoring turned on at all times, which makes its energy retention horrible at lower speeds.

That graphic show the Su-30sm having a Similar FM as Mirage 2000 at the bottom above them its the Su-33.

Even if its thrust vectoring is off, its energy retention will still be terrible becuase of its FM and its weight.

How?

It has nothing to do with the TVC. The plane ATM its too heavy and as people has point out it use the old Oswald efficiency. People should cut it off with the TVC making the plane losing speed. All of that its Controlled by the FBW system. Ensuring the best performance or that its how it should work.

It was talking about the segment line at the bottom. In the solid line for turn both su-30sm and F-15e start about the same. But you can see how the su-30sm lose to the F-15e.

True, though that would still be an improvement. A big reason why the energy retention is so bad is because of TVC. The other part comes from weight and the oswald efficiency value being lower than the other Flankers. For context, a value of 0.47 for FlapsPolar0 is what the Su-27 had before the FM buff, when it was then brought to 0.54

Man I wish Gaijin would lean in on the Russian bias a little, really want the 30SM to get better engines

why tf are they changing oswald coefficient again? Shouldn’t they keep it the same as the other flankers?

They should’ve. Maybe they recycled the old Su-27 flight model and just changed it by adding canards and TVC engines. Or maybe they just forgot what values they need to give it. Its a mystery.

anyways dev server only has a day left. Su-30SM is gonna be super mid on release

Cant that be due of canards?
Like… its not old Su-27 FM, oswald is different

Su-33 and 34 also has canards

This plane don’t make sense. If the plane its this bad compare to even the Su-27sm. What was the thing that impress Russian Officials?. What was the advantage it have. Because this thing is Contemporary to Su-35s. And you can even said it a bit newer. I know its cheaper than the Su-35. But it don’t make sense to build this thing over old Su-27sm/2/3.

It have way worst Radar than Su-35s. Worst engine. Worst range. Worst flying performance. For 10m difference in price.
