Physics of Artificial Gravity

Abstract

Potential technologies for achieving artificial gravity in a space vehicle are now discussed. We begin with a series of definitions and a general description of the rotational dynamics responsible for the forces ultimately exerted on the human body during centrifugation. These include gravity level, gravity gradient, and the Coriolis force. Human factors considerations and comfort limits associated with a rotating environment are then discussed. Finally, engineering options for designing space vehicles with artificial gravity are presented. Figure 2-01.
