Mikoyan-Gurevich MiG-29 Fulcrum - History, Design, Performance & Dissection (Part 1)

I have, only two dozen times. He doesn’t wish to reply there and continues to spread misinformation and walls of text full of nonsense. Now hush, there is legitimate discussion happening.

I don’t think that insulting them will make them more inclined to reason.

I need the following books to further appeal the report:

  1. The theory of gas turbine engines under.ed Nechaeva Yu.A . tom
  2. Theory and calculation of air-jet engines /under TT3 ed. by S.M.Shlyakhtenko

If anyone has these, I would like to obtain them. Further official documentation on the MiG-29’s intakes or RD-33 is also welcome.

Also, this is odd. Surely not just insults and nonsense.

Tbh it would be nice if you grew a pair, and man up.

Secondly, I thought you had @MiG_23M blocked. I advise you do the same for me.

Tbh.

Why would I want to engage with you privately?

So, you can beg me to stop “bullying” you here? Like previously?

Please show us how this definition is wrong & how it applies to leading edge flaps.

You keep taking shots. Misinformation? You are being dramatic sweety. Show me what “misinformation” I was spreading? You made the accusation. Prove it.

I complimented your report, but you want to keep taking shots because?

So, I shall keep pointing out your poor reading comprehension and aeronautical knowledge and highlight your only education in tractors.

I do not think you are spreading misinformation whatsoever. I just think (know) you are a highly uneducated man with nothing more than a high school diploma from some random Appalachian town that gets carried away with his magical interpretations, that’s all.

are these russian language books or english as written?

They are Russian language books, I have obtained the first one online but I need the second one as a secondary source.

I’m not trying to offend anyone. I’m just stating the fact that the developer doesn’t want to listen and figure it out.
The only difference between the engines on the stand and in the aircraft is the air intake path.

is this the title of the latter in russian?

if so I have a copy I can DM

I believe so, I may have already obtained a copy but DM me anyway. I am going to go through these.

The developer, as usual, is blatantly lying
First, the rotation speed remains unchanged in Full Afterburner

Secondly, he says that the automation of the air intake will not give more air, wedge is fully open

He says that the flow is not uniform, but this reduces the efficiency of the compressor, but does not affect the air flow in any way
The developer continues to blatantly lie

I am a little confused how the airflow is not uniform.

@BBCRF what about in regard to high angles of attack and Intake Louvers? There should be zero flight regimes where the airflow is not uniform.

The MiG-29 is the world’s first aircraft fitted with dual-mode air intakes.

This refers to the uneven flow around the compressor blades

You are 100% correct and the Devs have their reasons beyond what is technical. It is a competitive game of balance and most importantly it is a business.

It is something we must always consider when dealing with them.

However, every time you all document these discrepancies it does help.

Man, after @EpicBlitzkrieg87 's Mig23 thread back in the day and how hard it was to get them to move on the Mig23M performance, took months and all of Red Skies and following patch to get fixed (still think its missing acceleration), I almost want to say there is no way in hell Russian bias exist.

But how? In high angles of attack? Or basic ass subsonic/transonic level flight? I am just trying to get a perspective of what the devs see and it’s not making sense to me.

Are they even considering the dual-mode air intakes? Which literally serve to reduce uneven airflow in flight, especially at high angles of attack?

We all understand what distorted airflow can do to a compressor blade, such as reduced thrust. Too much can lead to a flameout.

In what flight regime does the RD-33 suffer from uneven airflow? The entire flight envelope? Did they say?

Fun fact.

Do you know what fighter adopted Mikoyan’s (first in the world) Dual Mode Air Intake Louvers of the Mig29?

The F-22 Raptor.

I do not think many of you or GJ truly understands or appreciates just how special the Fulcrum is, how it shaped western combat doctrine as well as air superiority fighter design of the 5th generation.

Mikoyan understood how critical dual mode air intake technology is regarding designing the Mig29M,

After redesigning LERXs, with the intake louvers on top eliminated, and FOD protection provided by intake screens. In the time-honored Soviet tradition of “maskirovka (masquerade / deception)”, early MiG-29Ms apparently had louvers painted on the LERXs to camouflage the fact that they were new-model aircraft.

It is a key feature Western analyst look for when new Soviet/Russian aircraft appear.

Gaijin’s so called “Russian bias” in action. UFO F-16’s with borderline unflareable missiles fighting MiG-29’s which are treated as having not even fully open air intakes where a magic unevidenced design flaw conveniently cripples the plane.
