再生式环控生保技术研究及进展

Research and Development of Technique of Regenerative Environmental Control and Life Support System

环控生保系统 (ECLSS) ,是载人航天器最具载人航天特征的一个重要系统 ,是直接关系到航天员生命安全的不可缺少的保障条件。本文介绍了构成再生生保系统氧、水闭路的主要技术 ,比较、分析了各技术的优劣 ,指出了今后研究发展的方向。

Environmental control and life support system (ECLSS) is a critical subsystem of manned spacecraft that has the most typical characteristics of manned space flight. It is an indispensable safeguard for the life of astronaut in space. This article reviewed the main techniques and developments of oxygen and water closed loop recycling in regenerative environmental control and life support system. Through comparing and analyzing the current state of its space application as well as the strong and weak points of different technique routes, the directions of research and development of oxygen and water recycling technique for space station are proposed.
