Abstract：Objective To determine the limit heat insulation ability ( heat leakage rate) for whole spacesuit system during extravehicular activity and to validate the passive thermal protection structural design. MethodsThe limit space thermal environment that might be met during EVA was simulated with SindaG and NEVADA software. The space thermal environment was simulated with a infrared heating cage and liquid nitrogen device, and a thermal manikin was developed to simulate human metabolic heat and temperature distribution in spacesuit. Results A manikin-spacesuit-environment synthesis system and a validation method by compared test data among normal vacuum and different space heat flux status for spacesuit thermal insulation test was built.Conclusion The limit thermal insulation protection performance of the "Feitian" EVA spacesuit is validated in simulated space environment. A reliable and accurate test results are gained.
