Effects of Exposure to a Rotating Environment (10 Rpm) on Four Aviators for a Period of Twelve Days.

Four carefully selected military personnel undergoing flight training were exposed to constant rotation at a speed of 10 RPM for 12 days in the Pensacola Slow Rotation Room. Environmental and working conditions simulated in many respects those which might obtain in a rotating orbiting spacecraft. The findings are discussed under three headings: clinical symptoms, clinical laboratory findings and psychophysiological performance. The experiment has demonstrated that countermeasures in addition to adaption are needed if there is immediate exposure to rotational velocities of 10 R P M and that the rotating room is a useful device for further exploration of vestibular and central nervous system mechanisms.
