Seems like there is already a mechanism, sans moving parts, of generating force post-launch. Not saying it is sufficient to correct a ground-launched, ballistic projectile though.
> A solid rocket almost certainly will spontaneously RUD when heavy acceleration is applied
I am skeptical that there is no chemical propellant capable of resisting the initial acceleration. That seems like a bold claim.
What about gas-based thrusters(i.e. ion drive with xenon or even just nitrogen gas)?
- cjensen 4y agoThe LEO post-launch force you link to is for minor orbital changes. Or large changes over a large amount of time. The problem with an orbit that begins at the ground is that you have exactly one orbit's worth of time in which to convert it into a real orbit. Magnetic or ion propulsion won't cut it. My comment about solid rockets is due to the fact that they include fully combustable fuel in a ready-to-use mix. Solid rockets don't require much input to get them to combust. I assume no one is considering solid rockets for this application; I only mention it as part of assuming they would need a liquid rocket so I could explain the problem with liquid rockets which rely on pumps and pipes.

- amanaplanacanal 4y agoI guess the problem then becomes designing an explosive bolt that can survive the 10,000G launch without exploding.
