I have so many questions..! (And maybe the answers are somewhere on the page, but its navigational paradigm is too atrocious for me to handle)
- how fast do you have to push something through the atmosphere to have it reach space?
- and, how fast is the lever spinning to reach that velocity? how precise do you have to time the release?
- after release, your lever is going to be pretty unbalanced. having seen what happens to an unbalanced ultracentrifuge in a lab (spinning a few grams of biological samples), how does this thing launch a 100kg satellite without wrecking the launch station?
- does this mean all the remaining angular momentum is in an opposite weight you discard simultaneously by slamming it into the ground? do you just sling the payload around in some ridiculously unbalanced manner?
- can you launch things with liquids (eg., fuel) at all due to crazy sloshing mechanics?
- isoprophlex 2y agoOkay so say 15.000 km/h, escape velocity + compensate for drag. At a 100 meter radius, that's a radial velocity of 41 radians per second (4100 meter/second) => 6.5 Hz spinning rate, or one full circle every 0.15 sec To hit the exit at an angle that's within 1 degree of target, that requires you to launch with 0.15/360=0.4 millisecond precision. Which seems... not entirely unhinged? Those 1000s of g-forces though...
- citizenkrank 2y agoYou could possibly add a lot of weight on both sides of the spinning wheel, so the lost weight of the payload would not matter as much. Or maybe put a weight at the opposite end that moves towards the center as you release the payload, compensating for the lost weight at the other end? (* in terms of angular momentum)
