Artificial gravity wheels make people sick or other side affects?

[CrashyMcCrashFace]

i.e. The Martian Hermes. I understand the physics of creating artificial gravity but it is still rotating so the human body is never stable. Could it be slow enough for the affects to be negligible? Astronauts could get used to it but that doesn't mean there are not silent affects of the constant spinning.

It definitely will be different, but there aren't any known health issues (afaik), and if there were they'd likely be less problematic than free fall.

One thing I'm not sure about is if you were switching frequently between a ring and weightlessness, say from moving between the center and edge of the ring daily. People seem to take a while to adjust to one after being in the other, and not having that time might be more problematic than just being in a ring.

Don't forget the nausea limit...

 

In general, the larger the sweep radius, the fewer the physiological issues.

Yeah. A slow, big centrifuge is going to be tolerated a lot better than a small, fast one.

You can however reduce the sideeffects by lowering the "gravity" there is very little data about the whole topic, but if you reduce the gravity to say, 0.5 G you can get away with a smaller, slower spinning wheel.

I'm not sure how up to date or valid it is but I found this calculator pretty useful when thinking about a grav-wheel equipped spacecraft for a story plot.

The truth is, we have no idea. As long as there are no actual experiments with variable speeds and wheel diameters and G levels, we will never know if the idea is feasible or not.

And it is technically difficult to develop a seal joint that can maintain pressure and the mechanical characteristics, which means that developing a test bed where we can do this testing is challenging (which means expensive). You'd be better off spinning the whole ship that having a gravity wheel as shown in sci-fi.

And here's some guy with a low G-tolerance going in it.

You mention low-G ?

And all the behind-the-scenes, in sequential order :

 

 

 

TL;DR if you already have nausea problems, it won't go very well.

Manley did a great video on this a bit ago (within the past year?).  He was specifically looking at the asteroids being spun up for 1g effects, but he also looked at smaller wheels too.   I believe his conclusions were that the Coriolis effect would be too strong to overcome getting severely nauseous.

If you make the ring big enough you won't get any severe health problems. You can also lay down most at the time, to make the gravity more even.

Good content from a "normal" perspective.

And is a bloke.

And yeah, the string of events he had with G-forces is quite something to say [censored] !

 

Although back on topic, it really depends on how "tough" you are. If you're that BadS who can withstand 3-4G without forced breathing, perhaps you won't feel anything from a small 1G centrifuge. If you're someone who can't even stand that, perhaps you won't go to space anytime soon.

Or rotate a non-pressurized wheel inside a large pressurized hull, as whole ship rotation gives a whole bunch of other problems.
Or make an endless  train moving along the inner side of a large pressurized hull.

Found it

Edit:  Nope not it.   Similar topic, but he discusses the Coriolis effect on these stations in the one I'm looking for....
