Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection
Please stay on the topic at hand.
The R-77 has 4 airbrakes? This level of Ameriboo cope in WT.
We have dude named after Mikoyan’s worst fighter in history claiming the grid fins on the R-77 are actually airbrakes.
Do you have a single shred of evidence they are airbrakes & can be used as such?
Does the MICA also not have a sustainer? Because both it and R77 seem to woble a ton once the booster goes out, probably those oscillations mentioned in the devblogs

I never said that they were airbrakes in the R-77’s implementation. Only in the falcon 9’s.
What is your goal here? To discredit yourself in every way possible?
You are entitled to you own opinions regardless of how absurd they are. But you have zero proof.
They are specifically control surfaces.
Soviet Union invented the technology they are exclusively used for control surfaces. Just like the R-77.
Your buddy is agreeing (concurs) to that notion right now in the topic about soviet space rockets. They are not airbrakes. @Celestia does actually know alot about rockets. I am impressed.
As I said earlier, they have multiple uses and are optimized for different things. They are optimized on the falcon 9 for higher drag. They are required to slow the rocket down. The R-77’s minimize drag to improve performance.
In one case they are airbrakes, in the other they are primarily there to enhance end-game maneuverability and precision.
Him agreeing or not is irrelevant, you can’t make claims and then post sources that debunk them only to then ask others to also debunk your claim as well. Makes literally no sense.
What you say does not interest me k-12.
please refrain from replying unless you can describe how does the grid fins work as air brakes for the R-77.
Because we have enough Ameriboo misinformation going around in attempt to downplay technological marvels we enjoy today because of the Soviet Union.
I don’t think anyone claimed that. Is that your claim now?
My mistake.

The key difference between the grid fins used by space X, and those used by the R77, is that the R77 actually attempts to reduce drag in their design while space X is trying to create as much as possible.
Compare close up photos of the fins of both.
The space X fins are like 1cm thick and NOT tapered on the leading edges. They are as flat as pancakes.

They do have tapered leading edges.
1cm thick is not relevant it’s a much larger & heavier rocket than the R-77
(just a little bigger as you can see)
Cmon bro, be reasonable.
:)
Let me guess, you were looking at the grid fins backwards?
Is this what you saw? Yeah, the outside is the back side of the control surface. The inside is the leading edges.
Perhaps we are all a little new to the technology of this industry? We can learn together.
:)
Be careful, my ability to pick this stuff up is very quick. I love reading.
“Correct a wise man, he will always be wise.”
It is still relevant and he’s not discussing the points. He is discussing the taper of the leading to trailing edge.
A very thin blade at the tip slices air better, stalls the wave drag issue.

All control surfaces induce drag in operation.
The reason the grid fins are 1cm this is appropriate for its size to generate enough mechanical force to change the attitude of the rocket.
The fact they are 1cm thick is not evident that they are used to slow the rocket down. That is the booster’s responsibility. The controls fins, control the rockets attitude just as the R-77.
They are tapered because slowing the rocket down is not its responsibility nor is it effective whatsoever in slowing down a massive rocket of its size in reentry.
Again, the grid fins of the R-77, Russian ICBMS & Falcon 9 all have the same precise operational use.
This technology was invented by the once great & feared Soviet Union & is still obviously in use today.
That’s not how grid fin design works
They manipulate the airflow around a rockets surface.
They are literally called surface controls.
Grid fins are one type. Go to school.
The valleys are necessary because of how thick it is to break up wave drag issues, the R-77 doesn’t use them because cost is already high to manufacture with the ultra thin blade like fin tips.
I have been going to school for the last four years but you wouldn’t know…
The grid fins fence thickness is small for missiles… Drag is not preferred, large for MOAB & Falcon 9 as the additional drag is preferred.

thats fine, gaijin need to take more money from the largest players group of WarThunder LOL

Good job, son. Thats only half the battle.
Its surviving in the private sector. You have no experience in the real world. Let me know when you get out there.
I swear I will give you the respect you deserve when you actually make it. You want to bring up my life outside of education. Well then you are acutely aware I have overcome many things in life and are successful to say the least. Get out there & show me.
Been out there for two years now, thanks
I made it before I met you, of course I didn’t have a 10 year delay either.
