Rockets being passé, China is working on using an electromagnetic railgun to launch crewed spacecraft the size of a Boeing 737, weighing 50 tonnes, into orbit. This remarkably ambitious project is even more ambitious than it seems at first glance.
And not get crushed by the G forces how exactly?
humans can still function when insane G forces have turned them into jelly right?
While railguns are known for rapidly accelerating projectiles to hypersonic speeds over the short length of a gun barrel, there’s no limit on how slowly they can accelerate something or how long the “rail” part of the railgun can be. Accelerating “slowly” over a long distance is totally possible!
Sure, but it’s gonna require one hell of a long rail…
Make it a circular rail with an off-ramp; like a particle accelerator. Still very ambitious.
That would put the g-forces back in play: the faster you go around the rail the stronger the centripetal force that keeps you going in a circle. If the rail is straight the force only depends on acceleration not speed.
I hereby dub any crew member sent to space in this manner a Cannonaut.
你们中有些人可能会死，但这是我愿意冒的风险
Just to save you guys a click, this is a Google translate of, “some of you may die but that is a risk I’m willing to take”
yeet
Maybe even megayeet.
But I sure hope they can pull this off.
That initial acceleration is gonna be a bit shitty.
If you want to reach LEO velocity and stay under 5g, you’d need a 860km long railgun…
