As long as your payload is a steel ball it might work, but 10 kilo G force would crush a golf ball.
By my calculations, a centrifuge the size of a football field moving at 5000mph would produce 5,576Gs.
There’s something in the description that can’t be right. Is there any construction material that could withstand that? It would have 233 rotations per minute. Four rotations per second. Something just can’t be translated right here.
While the centrifuge is up-and-running, why not share the cost among 200 “hardened” satellites, and fling them into space inititiated from an ocean-facing launch ramp?
