POTASSIUM SUPEROXIDE PASSIVE AIR REGENERATION STUDIES FOR MANNED SEALED ENVIRONMENTS

摘要

The feasibility of using solid chemicals passively to absorb water vapor, remove carbon dioxide, and supply oxygen in sealed environments for life support in aerospace flight was investigated. Sealed environment research using humans as subjects demonstrated that proper regeneration of the air can be attained without using blowers, fans, or electric power. The sealed environment experimentation indicates that approximately 0.33 pound of potassium superoxide per hour is required to passively regenerate the sealed environment for one man and to supply metabolic oxygen without using electric power.
