SURVEY OF THERMAL CONTROL TECHNIQUES FOR EXTRAVEHICULAR SPACE SUITS.

Abstract

Thermal protection of the extravehicular astronaut was studied with particular attention to the relationship between thermal protection and mobility. The space thermal environment was reviewed with respect to the sources and magnitudes of heat energy delivered to the astronaut. The astronaut's thermal physiology was investigated. The basic thermal processes available for controlling the space suit temperature were considered and the state-of-the-art of active and passive thermal control systems was reviewed. The study concludes that a passive system alone cannot provide adequate extravehicular thermal protection. Recommendations are made for investigating hybrid thermal control systems and for studying means to improve the thermal protection of gloves with adequate tactility. (Author)
