载人航天器舱内地面环境污染分析与控制方法

Contamination analysis and control in the cabin of manned spacecraft during the assembly integrated test

摘要: 文章阐述了载人航天器地面总装过程环境控制技术的国内外研究现状，提出以控制载人航天器总装过程舱内污染物浓度为目标，分析可能污染源、筛选重点监控目标污染物种类、研究污染物采样分析技术、确定目标污染物最大容许浓度的系统研究总装过程舱内污染物控制的技术方案，初步研制了污染控制装置并在载人飞船上进行了验证，取得了较好的效果，为保障航天员在舱内环境中的生命安全创造了有利条件。

Abstract: This paper studies the contamination concentration in manned spacecraft during the assembly integrated test, proposes a contamination control program of the cabin of manned spacecraft based on the analysis of the pollution sources and the major kinds of target contamination, the sampling analysis technology, and the max-tolerance concentration of target-contamination. A contamination control device is developed, and tested and verified on manned spacecraft. The results show that it can create a favorable living condition for the astronaut in the cabin.
