Potential Problems Related To Weightlessness And Artificial Gravity

This book reviews the principle and rationale for using artificial gravity during space missions, and describes the current options proposed, including a short-radius centrifuge contained within a spacecraft. Experts provide recommendations on the research needed to assess whether or not short-radius centrifuge workouts can help limit deconditioning of physiological systems. Many detailed illustrations are included.

What Is Artificial Gravity The production of an inertial force that simulates the effects of a gravitational force, often by rotation, is known as the generation of artificial gravity.Instead of the force experienced in linear acceleration, which, according to the equivalence principle, cannot be differentiated from gravity, artificial gravity, also known as rotational gravity, is the appearance of a centrifugal force in a rotating frame of reference.The term "artificial gravity" may also be used to refer to the impact of linear acceleration, such as that produced by a rocket engine. This is a broader definition of the term.

The ability of test subjects to perform operational type tasks was evaluated at rotational rates to 6 rpm and radii to 78 ft (24 m). The tasks included fine motor activity, mental operations, postural equilibrium, cargo handling, radial and tangential locomotion. Performance data indicate that 6 rpm presents a physiological limit at radii to 75 ft (23 m). Radial locomotion was not found to produce excessive adverse stimuli, and tangential locomotion was readily accomplished at walking rates of 2 of 4.8 ft/s (.6 to 1.4 m/s). The absence of vision dramatically reduced an individual's postural equilibrium during rotation. The use of selected anti-motion pharmaceuticals had, generally, a positive effect upon psychomotor performance at 6 rpm, but did not prove to be a panacea for the adverse effects of rotation at this rate.

The problems of space flight as they relate to the visual mechanism are disc ssed. Substantial portions of the Brown report are quoted in the present report. This report, in addition to updating the Brown report, presents a considerable amount of additional information regarding specific critical visual problems, as well as a recently compiled, extensive bibliography of research in this field.
