Abstract:

Three pressure suits, both pressurized and unpressurized, were compared on the basis of times taken by two subjects to initiate action and to reach to and operate controls located in various positions in a simulated workspace. The suits compared were the Apollo Phase B, the Gemini G2C-1, and the Apollo 1960 State-of-the-Art. The controls used were knobs, toggle switches, and pushbuttons. The work area investigated was semicircular, extending left and right 78 degrees, 34 to 49 inches above the floor, at a distance of approximately 2 feet. Average times for each combination of suit, suit condition pressurized or unpressurized, control type, control location, and hand used are presented. No suit appeared to be unequivocally superior. Total time to initiate action and to reach to and operate toggle switches and pushbuttons was typically, although not universally, shorter when wearing the Apollo 1960 State-of-the-Art suit. Total time to initiate action and to reach to and operate knobs was typically, although not universally, shorter when wearing the Gemini G2C-1 suit however, not all locations could be reached when wearing this suit.
