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

The thing is R-77 seem to pull about 30° AoA and 30Gs at best in game even with tac-view that loves show exaggerated numbers

@Celestia

but it will always be worse at BVR than the AIM120

At maximum range it should remain harder to dodge due to 40° AoA and high G overload at lower speeds than AIM-120

Which I already clarified in the rest of my post:

@Celestia

The grid fins should give better low speed responsiveness, bit that doesn’t have much use unless the missile is at the edge of its envelope (speeds below mach 1) and the target aircraft evades at the last moment. Any other missile would be reliant on the aircraft flying Into the misisle, whereas the R77 could still make one more effective manuver to hit the target.

I don’t think that is currently modeled in warthunder.

Please do not quote out of context.

[Celestia]

Yep, which is why I believe the grid fins have the drag modeled, but the missile lacks the benefit of effective low speed maneuverability it should have.

[Ziggy1989]

Grid fins are better for supersonic flight.

Their weakness is transonic flight. Transonic flight for any missiles useless.

These applications are especially used in space rockets.

Once the R-77 pushes past transonic regimes its actually more aerodynamic than the Aim-120.

Say what you will about Russian/Soviet radars. Their aviation aerodynamics & ballistic missile designs are superb.

[MiG_23M]

I didn’t quote out of context, I just agreed that it should perform better in those conditions. It currently doesn’t.

Your post is literally above mine. I only quoted part of your post because quoting the whole thing deletes the whole quote and leaves it as just a reply for some reason if posted…

That is a transonic speed. Is useless to all missiles.

Space X uses Russian rockets by the way & grid fins.
This is 2015.

What type of fins does the British use for their space programs?

They use nothing. Because they can never achieve space exploration.

[MiG_23M]

Fins and grids can both be used as airbrakes. The grids on the falcon 9 are very much different than the ones used on the R-77.

Additionally, I don’t recall SpaceX using Russian rockets.

[Ziggy1989]

That is not a reentry vehicle. Those grid fins work exactly like the R-77. One way trip.

Escape speed of the earth at the surface is approximately 11.186 km/s. They would not use grid fins if they were not aerodynamically superior.

Yeah. I know it’s been a while since discussing space flight but yeah check it out pretty cool stuff.

[MiG_23M]

Those are air brakes on the Falcon 9, do not operate the same as the R-77’s grids.

The Falcon 9 uses no Russian rocket tech.

@MiG_23M

Why would the rocket need airbrakes to escape earth’s gravity?

Think with your mind for one second.

@MiG_23M

Bet

Yes, Space X uses Russian RD-180 engines on its Falcon 9 rocket.

Does spacex use russian engines? - Exploration of space (spaceheavens.com)

The booster doesn’t use tbe grid fins except for re-entry and landing.

The grid fins help slow it down from high suborbital speeds and at high angles of attack. This prevents them from needing as much fuel to slow down before landing. Grid fins also require smaller actuators, saving weight. The other benefit is accuracy. The grid fins provide very high precision for ordnance such as the MOAB or R-77, and likewise allow SpaceX to land the booster on a boat in the water.

The use of the fin as an airbrake and to slow the rocket down demanded different grid shape than what is seen on the R-77 which benefits much in the same way - but optimized the grid for low drag rather than higher drag.

The booster does not come with retry LMFAO.

In response to a question about the future of American spaceflight, Elon Musk said that Boeing and Lockheed have relied too much on the Russian RD-180 engine.

No Russian tech?

[_Fantom2451]

Cos Falcon 9 has returnable first stage

[Celestia]

lol

I have never read so much self owning

Hey, at least our countries have space programs.

[MiG_23M]

SpaceX doesn’t use those engines, they designed and produced their own. They use no Russian parts at all.

Heres more evidence we use Russian tech enjoy

@Celestia

Fully developed in good old U-S of A

Some inspiration may have been taken from soviet designs, they were extremely good at making very efficient rocket engines, much better than what the US could do at the time.

What inspiration does the British use in their space exploration?

The French? Or German?
