Near Future Traveller

[Condottiere]

Going by The Expanse, clearly identify actions, and items, that mitigate the effects of high acceleration, and to what extent.

Going by High Guard, if you restrict acceleration to two and nine tenths gee, you can go about your business, citizen.

I am not going by the Expanse, I am going by Traveller rules as found in the core books.

Seated and in a g-suit up to 2g can be tolerated for combat at TL7, 3g at TL8, stretching the rules you could allow a g-suit to allow toleration for the hours long 2g or 3g burns. But the long term effects of 5 or more hours of 2g or 3g are likely to heart damage and increased likelihood of strokes and the like.

g-tolerance drugs don't kick in until TL9, but I am starting to consider a TL8/TL9 boundary setting.

No gravitics, but g tolerance drugs and the jump drive invented...

At TL9 the 1-3 reaction drive reduces to 1.75% fuel, the 4 to 6 is now 2%.

g-drugs and a g-suit would allow for trained crews to flit about 3g routinely, with up to 4g being tolerable...

remote/robot with disadvantages TL9 reaction engines could go all the way to 15g (1 disadvantage, 25% increased fuel use) or even higher 16g (2 disadvantages, 50% increased fuel use). Even more useful in combat search and rescue...

the setting is starting to write itself.

Going by High Guard, no penalties (for humans), upto factor/one and nine tenths acceleration.

Automatic pass for pilots and flyers upto factor/two and nine tenths acceleration; easy pass for everyone else, or, if failed, minus one task penalty.

At this point, you start evaluating mitigating factors.

That's for combat, not for 10 hours of acceleration per trip for years on end.

That, I figured out quite a while back.

Between seventy to one hundred forty percent Terran gravitational norm.

I tend to stick to seventy percent, when I'm squeezed on engine performance, and/or fuel capacity.

 

[Sigtrygg]

Since I am fixated on the 10g hours, using 0.5g thrust will give you thrust gravity for 20 hours, I wonder what the lowest would be that still gives a benefit to normal physiology, would 0.33g for 30 hours be better for long duration travel on ships with no spin gravity?

 

[Condottiere]

A third is Mars norm, so whatever is recommended for that.
