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

Stop misquoting what I said. The F-22s vents open to the rear, as does the F-14 and SR-71s.

You claimed the F-22s were copied from the MiG-29 and that they were auxiliary intakes. This isn’t the case.

Anyone can just click on the little arrow top right of your post if they need to see more context. Stop the antics.

Yay more of his math. LMFAO

Are the animations correct? I don’t know I haven’t looked. Are you wrong? Absolutely. The vents you have been referring to on the Su-27 do not function the same way as the intakes on the MiG-29.

Ah I see. You don’t know if the intake louvers open in flight for the Su-27 or Mig-29 at angles of attack…

But you are certain I am wrong though?

lol dude you are obsessed. Its a little scary tbh.
GG boys gtg. This was funny.

They don’t function the same… GJ seems to agree with me… ENJOY!

A couple videos of these ‘intakes’ as you’ve referred to them on the Su-27 from the game does not validate anything you’ve said. You even claimed the F-22’s pressure relief doors were intakes.

Just provide a source that agrees with what you’re claiming. The schedules for the operation of these parts of the intake is in the respective manuals for the MiG-29 and the Su-27. They do not function as you claim.

I found where my math error was. I took gross weight only, not empty + fuel weight.

Are these publicly searchable or have they been posted here?

In regards to the Su-27s vent under the intake the manual appears to state they are spring loaded and open / shut based on airflow alone. Each vent can open or shut as air pushes on it and thus is a function of aerodynamic pressure and not AoA. There appears to be no hydraulic drive of any kind forcing them open during maneuvers. When the mesh FOD door is up the pressure from the intake and lack of airflow under the plane will generally keep them shut.

For the MiG-29, the auxiliary intakes do not have ready access to incoming air during the cobra maneuver, rather the engine just loses thrust during such moments because of the restricted airflow. Luckily, the RD-33 is resistant to flameouts during such maneuvers.

I must reiterate: the Su-27 stalls to perform the Cobra, the F-22s overpressure vents are not intakes copied from the MiG-29, and Ziggy has no clue what he’s discussing as he has not read the manuals. He needs to stop making stuff up on the spot.

Both

NO DUH

You thought they were hydraulic?! lol.

lol if you are under any angle of attack what does that mean, genius?

Airflow pushes the doors down and feeds the engines for optimal engine output when flying at angle of attack. That is why they only open at ANGLE OF ATTACK.

They do not open in regular flight. They operate entirely on airflow that pushes the doors down in angle of attack.

He literally defeated his own argument.

You indicated it was reliant on angle of attack with the context that it was activated on an electronic schedule and yet it is still blocked by the FOD door. It doesn’t function as you’ve described.

No, I was incorrect. Suction from the intake pulls them up as needed when more airflow is required.

No, they also open when engine is under load and aircraft is at slow speeds except when FOD door is down all the way.

That is false.

You tried to make it seem like you knew all along and then blew it lol

We are getting somewhere :)

“with the context was activated on a electric schedule”

lol nope, just good old fashion airflow at angle of attack. I never said, “electronic schedule”.

“The suction from the intake pulls them as needed.” he says.

“When the engine is under a load”

Holy crap, he still trying to act like he knows what he’s talking about.

They do not open on the ground. They do not open in straight level flight.

They only open in… angle of attack.

:)

He’s slowly figuring it out, we should give him some more time. he’ll get there.

You literally haven’t read into the subject at all and come from the pretense that you’re well read on the subject. Had you actually read into the subject you wouldn’t be making your claims in the first place.

The doors are spring loaded, when there is airflow under the nacelle of sufficient pressure or loading from the engine the doors will open. This is seen both in high alpha flight as well as simple level flight or banking maneuvers. Sometimes even during simple rolls.

In-game they operate solely with AoA and this is technically incorrect but I see no reason for them to add many lines of code to manage the doors individually or during all of these transients.

The smug act just doesn’t look good on you when there isn’t anything to be smug about. You still won’t acknowledge all of the other erroneous claims, you wish to move on like they never happened…

The intake louvers open in angles of attack. Nothing more. Nothing less.

Get over it.

:)

F-18 can do some 40+ degrees with free throttle movement and the F-35 can do so at 55° with no concerns for departure. Neither are considered “supermaneuverable” lmao

That’s not what the manual or pics / video suggest, your initial claims are still erroneous and based on thin air.

You can look at it however you want, write in any language & call it whatever you want.

I do not care how you cope with reality. I do not care how you come to terms with the truth. As long as you do it quickly & stop wasting my time.

The intake louvers work entirely on airflow at angle of attack.

End of discussion.

They don’t though, show me in the manual where it states that… Only way for you to end the discussion is to stop talking lol

After 32 AoA, track stability is lost to angles of about 45 degrees

Then why would you ask me to show you the manual?

Because it does not matter what I show you will continue to derail.

When you bank. Alpha
When you aileron roll. Alpha.

Any maneuver that requires use of the elevators produces angle of attack.

The intake louvers operate entire on angle of attack & allow the Saturn engines to breathe efficiently when performing dynamic decelerations other supermaneuverable techniques in which no American fighter ever put in service of the 4th generation is capable.

In effect, the elevators are the angle of attack control. When back pressure is applied on the control, the tail lowers and the nose rises, thus increasing the wing’s angle of attack and lift.
