Thermal performance analysis of antigravity suit

To study the thermal performance of an antigravity suit, the thermal system simulation modal was build among human body, antigravity suit and environment. The suit was divided into 15 segments, each segment has different thermal resistance and gas permeability. The system heat and mass transfer process were analyzed according to suit characteristic. This modal can simulate human body skin temperature, core temperature and sweat. The combined index of heat stress (CIHS) was calculated with these parameter to evaluating human body hot load. Experiments were designated to validate the modal calculation results. The differences between experimental and calculating results is small. At last, influences of the suit thermal resistance and impermeability index to body hot load ware analyzed with the modal built above.
