Operational Characteristics:
- C hronic exposures (with stops for animal
husbandry) to 4G
- Small animals, plants
- C ontinuous data and video acquisition
- R otational and stationary controls
- ISS C entrifuge habitat configurable
The 8-Foot Diameter Centrifuge is designed to
accommodate habitats developed for the
International Space Station (ISS). Four
radial arms are configured to handle 14
inches to 24.5 inches high (8 to 14 "Panel
Units") habitats for acute or chronic studies.
E ach of the four stations has a swing bucket
and a liner assembly containing three sets
of ISS-compatible slide guides. The ISS
habitats can be positioned 52.88 inches to
63.67 inches from the center of rotation with
a resulting acceleration range of 2.86 to 4G
at the maximum rotational rate of 42.3
R PM. E ach ISS habitat may weigh up to
192 lbs. A n ISS-compliant water coolant
loop is available onboard the centrifuge to
cool habitats. E lectrical connections for the habitats are made via ISS-like connectors.
C ontinuous habitat data and video are available onboard using an optical slip ring pathway. Standard A C power is provided through mechanical slip rings to power onboard DC power supplies.
N on-ISS payloads may be accommodated
on the centrifuge merely by using standard
swing buckets and existing mechanical,
instrumentation-quality slip rings. The ISS
swing buckets (without liner assemblies)
can also be used to secure smaller payloads.
