Abstract—

A rationale for the concept and strategy of monitoring of the atmospheric chemical composition and water quality are provided for manned spacecraft to be used for long-term and interplanetary flights. The main risk factors are formulated for a change in atmospheric and water composition during interplanetary space flights. A promising version of the analytical system for operational control of air and water quality in manned spacecraft is described considering these risk factors. Several gas analysis methods are proposed to be used in this system to partially overlap the nomenclature of detected species with respect to particularly important (critical) species. The water quality in the system is monitored by two instruments: one for measuring the total carbon content and the other for analyzing the ionic composition of water.

长期和行星际飞行中的空气和水质监测

摘要—

为载人航天器用于长期和行星际飞行提供了监测大气化学成分和水质的概念和策略的基本原理。针对在行星际空间飞行期间大气和水成分的变化制定了主要风险因素。考虑到这些危险因素，描述了一种有前途的用于载人航天器的空气和水质运行控制分析系统。建议在该系统中使用几种气体分析方法，以相对于特别重要（关键）的物种部分重叠检测到的物种的命名法。系统中的水质由两种仪器监控：一种用于测量总碳含量，另一种用于分析水的离子组成。
