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.
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.
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.
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.
Why would the rocket need airbrakes to escape earth’s gravity?
Think with your mind for one second.
Bet
Yes, Space X uses Russian RD-180 engines on its Falcon 9 rocket.

GET WRECKED

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?
Cos Falcon 9 has returnable first stage
lol
I have never read so much self owning
Hey, at least our countries have space programs.
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
What inspiration does the British use in their space exploration?
The French? Or German?
First of all, you moved the goal post from Russian rockets to Russian engines, proved wrong on both and now you’re saying we use Russian stuff in general at an even lower level… We were talking about SpaceX. They don’t use Russian equipment. They designed their own.
Yes we do, you changed to no & no Russian tech.
But we relied on both.
I just had a stroke trying to read this and understand it

They don’t tho
You’ve been wrong about all this stuff
