Factors Affecting Human Tolerance to Sustained Acceleration
Abstract
Six relaxed subjects were exposed on a centrifuge to increasing G pulses in order to determine their G tolerance. G protection was provided by supination and/or inflation of anti-G suit (AGS) bladders using a newly developed rapid response, servo controlled anti-G (SCAG) valve. Supination, alone or with the AGS, was most effective in increasing G tolerance. Increases in SCAG Valve outlet pressure were directly related to increases in G tolerance. Neither of two modes of SCAG valve operation caused any significant difference in G tolerance nor in assessment of AGS comfort. When protected by supination and the AGS , sufficiently increasing G onset times reduced G tolerance. Adverse comments and low ratings for AGS comfort followed exposure to most G pulses when the subjects were protected by high levels of AGS bladder pressure.
