Partial gravity simulators

SIMULATION, 1970
This article covers two partial-gravity simulators being used at the Manned Spacecraft Center to acquaint astronauts with the dynamics of moon walking. The first simulator discussed, the Partial Gravity Simulator (PGS), Figures 7 and 8, is a 5 + degrees-of-freedom simulator built into a 14 x 60 foot room which is 60 feet high.

Pneumatic Conveying of Materials at Partial Gravity

Journal of Aerospace Engineering, 1992
The feasibility of pneumatic transfer for the movement of regolith at a lunar base is evaluated. Operation of pneumatic conveying systems at partial (lunar and Mars) gravity on NASA's KC-135 aircraft allowed the determination of some key parameters necessary for the design of an operable system. Both horizontal and vertical transfer is studied.

Behavioral responses to partial-gravity conditions in rats

Neuroscience Letters, 2012
The effects of microgravity or hypergravity on living organisms have been studied extensively; however, thus far no studies have addressed the effects of "partial-gravity", that is, the low-gravity levels between the unit gravity (1G) on Earth and zero gravity (0 G) in space.
