Positioning System for a Human Habitat in a Large Centrifuge

A report describes the system for controlling the radial position and tilt of a spacecraftlike habitat for humans in NASA's Space Flight Environmental Simulator (SFES) — a 16-m-diameter centrifuge used previously to evaluate effects of hypergravitational acceleration on animals. The habitat-positioning system was installed as an upgrade of the SFES to enable similar testing on humans to obtain guidance for designing centrifugal artificial-gravitation systems for future spacecraft.
