Please source everything you have on “overpressure doors.”
Explain exactly how they work & why in your own word or source it thanks.
Also you need to confirm that neither the Su-27, Mig-29s & F-22s intake louvers are dependent on angle of attack.
Because in game for both Mig-29 & Su-27 they are. Because that is correct. Will you submit a report? Yes or no?
Firstly, they open facing the rear so they aren’t intakes. Just a visual inspection shows they do not operate in the way you claim. Secondly - you made the claim that they are intakes. You provided no source and now ask one of me.
So… you do not have any proof of a “overpressure door” is? LOL.
Does oxygen not exist in the rear?
lol.
You really want to keep getting smoked here? They are not intakes? Yes or No?
Real simple question. Did GJ model the intakes wrong for both the Su-27 & Mig-29
Yes or No?
In reference to the picture of the F-22 louvers.
Very likely a misleading statement, similar to the statement that the entire F-35B lift system was copied from the Yak-141.
Missed comparison, as person called the light F-18 to the heavy Su-27. It could also mean the legacy Hornet, but the F-18A/C is lighter regardless.
Made an incorrect comparison with the purpose of the MiG-29 and F-22 vents.
The fact that, after the manuever, the aircraft “slams” back nose first would indicate to me insufficient lift. It is not completely departing from flight, but the wings aren’t maintaining enough lift to continue the manuever. Couple this with the mass and momentum of the aircraft, I would reasonably assume it would not be able to hold higher AoA than what others have described.
They are there to maintain optimum intake pressure and to bleed out disruptive airflow. American jets have been using different methods to acheive this. F-14 and F-15 come to mind, I believe the B-2 also has this.
Who said this?
What I said is completely right when looking at both aircraft’s ability to fly under their own gross weight with their own engines. The Su-27 is lighter.
Do not compare them by simply looking at the weight. You must look at their ability to manipulate that weight in their entire flight envelope. The Su-27 can manage its weight better than the Hornet.
Yes, very correct. But those doors exist on the F15 & F-14 to regulate airflow in supersonic flight. The F-22 does not have these or need these.
The F-14 also has vents above the intakes on the back and predated the MiG-29 by a decade. The SR-71 had overpressure relief doors similarly and was flying since '64…
Nothing about the F-22 suggests it was copied or used from the MiG-29.
They do not open up and close based on angle of attack and close flush like the Mig-29, Su-27 & F-22
That is why they are called intake louvers. Not “overpressure doors” lol.
Look you do not even know what you are talking about first they are, then they are not, then they are intakes but the F-14 has them???
The Su-27s are located on the front when flown and face optimally in angle of attack. That is why they open in ANGLE OF ATTACK.
The MiG-29 and Su-27 manuals are public, please show me how they open based on angle of attack? What is the schedule for their opening / closing?
Let me also remind you that the vents you pointed to on the Su-27 are not part of an intake grill and the overpressure doors on the F-22 cannot function as you’ve described.
You’re spouting unsourced nonsense and want sources to debunk you…
Not suprisingly, a lot of Russian aircraft fanboys. Though I did not mean a statement made here, just a similar false comparison.
This is provably false, though I will give you some leeway since you may be conflating something. The Su-27 has a much better T/W ratio than the legacy Hornet, but due to the properties of momentum, I would conclude the Hornet has less issues during high AoA instances of flight.
This is actually controlled by the variable inlet ramp instead of relying on the bleed air door.
You need to show why they do not & how GJ got it wrong for the Su-27 & Mig-29.
Did GJ model them wrong yes, or no?
It’s a simple question. Just answer it so I can blow you up with sources.
I respect that.
I didn’t call them intakes, I said they are vents above the intakes in reference to overpressure relief which would imply an exhaust. That’s why they face the rear.
Only to be promptly blocked by the FOD door? What are you even claiming here?
(F-18C w/ GE-402 engines, the improved ones)
F-18C has a empty T/W of ~1.6
Su-27 has a empty T/W of ~1.4
On 50% internal fuel the F-18C has a T/W of 1.25
On 50% internal fuel the Su-27 has a T/W of 1.10
So no, the F-18 has better power to weight in most relevant conditions. It’s just slow because it has higher drag by design.
You did. You just do not remember because you are lying so much you forgot.
Sounds like you know the answer and have sources to back them up… But if that was the case you wouldn’t be making these absurd statements.
That was in reference to the mig-29 which indeed has auxiliary intakes… Nothing to do with F-14.
You drop it down & the Su-27 murders the F-18. You know how much fuel the Su27 carries little guy?
I do not understand why you cannot answer the question did GJ model the Su-27 & Mig-29, wrong yes or no?
Well I do, its because you actually have no idea lol.
50% internal fuel for Su-27 is a horrible comparison it is supposed to dogfight at no more than 30% lol
so ++ to zig for that coz wtf did u expect
For real, who picks 50% for an aircraft that hold a tremendous amount of fuel???
You put them in dogfight fuel states or min fuel. Those Saturn engines are taking you to the moon.
Mig-29??? forget about it.
30% fuel for the Su-27 is ~2,820kg of fuel
With that much fuel on both planes (benefitting the Su-27)…
F-18C w/ 2,820kg fuel: TWR of 1.21
Su-27 w/ 2,820kg fuel: TWR of 1.21
Interesting… So the Su-27 needs the F-18C to have a higher percentage fuel load to match its’ T/W… But which one of these is the fighter with “low T/W”?
At no point outside of vastly uneven comparisons does the Su-27 really beat out the F-18C in power to weight.
But you then said they are not intakes lol
This guy is all over the place lol.
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.
