Prototype of a New Lunar-Gravity Simulator for Astronaut Mobility Studies

The results of a study of existing lunar-gravity simulators indicated that a number of improvements could be made in the simulators being used to study the effects of reduced or lunar gravity on man's self-locomotive capability. This paper presents a review of a prototype lunar-gravity simulator which was designed, built, and delivered to NASA Langley Research Center by the Case Western Reserve Institute and the Cleveland Institute of Art. The simulator utilizes novel magnetic air bearings with constant-force motors and a unique body support system in that each of the body members are independently supported.
