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

Idk man. Its has always said. That No flanker have fully 3D TVC nozzles. Usually people discuss that Fully 3D. Its something like the on 29OVT. Or the one made for the Eurofighter. That can move in every single angle with not limitations. I know that its said that they work like 3D. So no much difference.

Now i have problem with what is the difference between both AL-31FP and AL-41F1s. I have always read that in AL-31FP only the Feather of the nozzle move. And that they are 2D but how they placed and how it move it make push the plane like 3D TVC. Yesterday i posted part 2 of this video to answer a question that @ILuvAnneHathaway did on another topic; ФГУП САЛЮТ модернизация АЛ-31Ф часть 1.VOB - YouTube

The video Show a Su-30MK/SM. And the test done by MMPP SALUT. On their work for an ALL-SPECT TVc Nozzle for the AL-31F engine. In the video they even show how its “Fully” 3D in a test bench and late they show how only the Feather move. This engine should have be AL-31FP.

But. This is a pic of AL-37FU. The engine of Su-37.
pc4_3 Made by Saturn. And late develop into 117s/AL-41F-1S.

And how its has always being describe the whole Nozzle move.

The thing its that if you look Pic of Su-30sm or even the Su-30mk. It look like they never use the TVC nozzle that Salut/Salyut made. An instead AL-31FP use AL-37FU/AL-41F1s one.

Now I’m really confused.

AL-31 only has single plane TVC, but the nozzles are placed at an angle to a pitch axis, to allow a combined thrust vector to be 3D. AL-41F1 has fully 3D nozzles that can work in multiple planes.

Here’s a YT video with Su-35S you can clearly see how nozzles move here

This engine was never installed on Su-37. Every single flight was done with AL-31FP. AL-37FU never went past prototype stage and all work done was later used in development of AL-41F.

Whole nozzle indeed moves, but on AL-31FP it can only move in a single plane, up and down if you want to describe it in a simpler language.

thats why su27m 710 would be better, if i remember right that one tested al41

AL-41F won’t fit inside Su-27. It was designed for MiG-1.44 project. Size was one of the main reasons for creating AL-41F1 that would fit Su-35S and Su-57 airframe.

double checked and yeah it seems to be tested with al41f1

Anyone know performance of n011 vs n011m?

Performance wise I can’t say much, N011 was barely used domestically, but technology wise it is N001 with Cassergain dish replaced with slotted planar array and additional air to ground bypass channel added. It seems also have some upgrades to the internals as well, most prominently 4 DL channels for Air to Air weaponry. Other than this there’s barely any info about it, T-10M program (aka Su-27M) was tested with N011M already, base version was only proposed for original Su-30 project that didn’t really took off due to budget constraints at that time.

n011 at least from what I can tell was put on early su-27m air frames, and n011m was only used from 711 onwards. n011 seems to be fairly similar to the zhuk of the mig 29 just scaled up.

Wikipedia says that it was 712 that was used for N011 tests. But it’s probably safe to assume that 711 got it as well during the time of being Su-37 demonstrator. Shame that 711 crashed afterwards.

I’m getting the info from this book which gaijin accepts for bug reports

I think you mean n011m not n011

Yeah, capability wise looks like scaled up version of N010. Man, I hope we will get Su-27M in some form in-game even if it will be a sidegrade to 27SM at best

I’m gonna put in a suggestion for 710, with n011 radar and al41f1 engine. Would be pretty good in game

Wikipedia specifically says N011 but I wouldn’t trust it with specifics. A lot of sources often confuse N011 and N011M with each other.

My book says SPECIFICALLY n011m was first used on 711 and 712. other su27m used n011

With AL-41 it would be interesting unit for sure. With AL-31 however it will be just worse version of Su-30SM because 27M airframe is even heavier than already heavy 30SM

I would believe your book as well, definitely more thrust worthy than Wikipedia. I also think I have this book on pdf stored somewhere, gotta read it as well.

Maybe BBCRF would be able to confirm if the engine in the image I sent was indeed an AL-41
