Spin Habitat

A Spin Habitat simulates gravity through centripetal acceleration.

• It is a type of Ship Equipment.
• It is one of the dominant technologies used before Grav Plates.

Description (Specifications)

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.

Habitats

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

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.

Control

Torque and progressional instability. Countered by:

• Counter-rotating pods.
• Counterweights.
• Stabilizing gyroscopes.
• Thrusters.

Coriolis effect.

• Targeting effects.
• Nausea.

History & Background (Dossier)

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.

Most spin habitats are external or ancillary structures on a ship, forming a distinctive part of the hull. A sufficiently large vessel may have internal spin habitats.
