ANALYSIS OF NONUNIFORM SUIT TEMPERATURES FOR SPACE SUITS IN ORBIT

Abstract

A cylindrical model of a space suit exposed to solar and metabolic heating is examined to determine the design criteria for minimizing equilibrium temperature differences. Resulting suit shell thicknesses are compared with those of a previous analysis that utilized the material thermal capacity and surface spectral properties to establish passive nonequilibrium temperature control. Results demonstrate that light-metal suits will develop small equilibrium temperature differences and be very heavy. Fabric suits of similar design will be even heavier. A water-filled suit shell is recommended as an attractive design approach if required circulation rates are practical. This is the second phase of an investigation to delineate the design parameters for controlling thermal environment in a space suit located in an orbit around the earth.
