In order to brake a space craft using air friction and a heat shield, the kinetic energy of the space craft must be transformed into heat. It happens due to the friction that heats up the heat shield.
It's heated because the air compresses, not because of friction. Also, the vast majority of that heat is just the air getting hot and then it transfers a bit from the heat shield.
The friction force is applied to the moving space craft to slow it down. It is the only way to stop!
It's heated because the air compresses, not because of friction.
The friction force depends on the velocity of the space craft and the density of the air.
It's heated because the air compresses, not because of friction.
The friction force may also rotate the space craft and make mince meat of anything inside. You have to ensure that the force is applied at the CoG of the space craft (all the time).
It's heated because the air compresses, not because of friction. Also, heat shields are really heavy which means that the CoG of a capsule tends to naturally point down because the lower part of the space craft is denser then the upper bit. The capsule also has thrusters to make sure it points the right way. If you think that the tiny bit of turbulence up there wound make an aerodynamically stable capsule tumble around then you clearly don't know what you are talking about.
The friction force may also buckle the space craft structure and rip it apart.
It's heated because the air compresses, not because of friction. Also, air has a very low viscosity so the effect you speak of isn't very big and it's definitely not enough to rip a heat shield apart.
The friction force may be 10 000's of Newton, i.e. quite much.
It's heated because the air compresses, not because of friction. By the way, how did you get that number?
The stop distance is quite long and if you intend to splash down in front of a ship ensure that you do not hit a mountain side before.
By the time a capsule gets lower then the peak of mount Everest it's already floating down on parachutes, so that's not a problem.
You don't know what you are talking about and have not won Heiwa's 1,000,000 challenge that you claim.
No,
you are the one who doesn't know anything about space travel. Ask anyone on this thread, I think they will agree with me.
