A Spin Habitat simulates gravity through centripetal acceleration.
A spin habitat simulates the effects of gravity through rotation, generating centripetal acceleration. This may be referred to as "centrifugal force gravity".
- Its rotation typically produces between 0.35 G and 1.1 G, a range in which most sophonts can live and work without adverse effects.
It consists of one or more habitats, which generally have their own Life Support and environmental systems.
- Tethered habitats (ie pods linked by cables)
- Tether materials.
- Spin pods.
- Arms (may contain elevators or ladders).
- Ring habitats (such as the hull of a Type L class Laboratory Ship).
- Rotational hull (generally cylinder configuration).
Rotation around a fixed axis.
- Up and down relative to the spin axis. Outward is downward.
Rotation speed vs distance from central spin axis.
- Rotation speeds in meters per second.
- Arm lengths are typically tens of meters.
- Physiological limitations on rotation rate.
Torque and progressional instability. Countered by:
- Counter-rotating pods.
- Stabilizing gyroscopes.
- Targeting effects.
Spin habitats are largely redundant due to the widespread availability of Grav Plates and Gravity Control Technology. However, they may still be employed by vessels constructed at TL-7 or less, or on vessels that may require a gravity-free environment such as Research Ships. Very large structures such as space stations or orbital arcologies may utilize spin habitat technology rather than costly gravitic devices.
- The Type L class Laboratory Ship is an example of a vessel that uses Spin Habitat technology.
Deliberately spinning a non-spin habitat vessel.
Spin habitats are generally locked during acceleration.
