That initial acceleration is gonna be a bit shitty.
Science Fiction
This magazine is aimed at fans and creators of sci-fi and related media of all kinds. It includes all content related to the sci-fi genre and only content related to the sci-fi genre. The goal is to build a community for everyone who enjoys science fiction and related topics. This includes the obvious books, movies, and TV shows, but also original writing, the discussion of writing SF, futuristic art and designs, and the science and technologies that inspire the sci-fi genre. **Team Top 20**
And not get crushed by the G forces how exactly?
The article states the company in question is only trying to achieve somewhere between Mach 1.6 and Mach 5. It will need a rail miles long, but more importantly the bulk of the velocity change needed to get to orbit will come from rockets.
It takes 9-10 km/s of delta-V in a real world scenario to get to low earth orbit. That’s about Mach 27 or so, a long ways away from Mach 1.6 or even Mach 5.
Crew must be made up of Uyghurs
yeet
Maybe even megayeet.
But I sure hope they can pull this off.
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.
They can call it the vomit comet.
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"
YOU BOYS LIKE MEXI-CO?!?!!
If you want to reach LEO velocity and stay under 5g, you'd need a 860km long railgun...
This was posted in the correct community, because it's about as real as the hyperloop
