本报告总结了作为科罗拉多大学航空航天工程科学系2002年秋季学期航天器生命支持系统设计课程（阿森5116）的一部分进行的贸易研究。它分析了目前的生命支持系统技术，并初步设计了一个综合系统，用于支持人类在前往火星和在火星表面的过程中。这项工作是根据美国宇航局人类探索火星的设计参考使命（DRM）[美国宇航局火星设计参考使命（DRM），附录3.0，来自万维网：http：//exploration.jsc.nasa.gov/marsref/contents.html]。综合设计分为四个子系统：水管理，大气管理，废物处理和食品供应。该过程始于从DRM导出顶层要求。在需要澄清的地方添加了附加系统和子系统级假设。根据性能因素确定和表征了候选技术。然后对每个子系统进行了贸易研究。由此产生的技术被集成到一个整体的设计解决方案，使用质量流量关系。系统级贸易研究产生了两种不同的配置-一种用于火星过境，另一种用于地表栖息地，其中包括就地资源利用。使用等效系统质量分析将每种设计与开环（不可再生）基线系统进行比较。(C)2003年国际宇宙航行联合会。由爱思唯尔有限公司出版。保留所有权利。
This report summarizes a trade study conducted as part of the Fall 2002 semester Spacecraft Life Support System Design course (ASEN 5116) in the Aerospace Engineering Sciences Department at the University of Colorado. It presents an analysis of current life support system technologies and a preliminary design of an integrated system for supporting humans during transit to and on the surface of the planet Mars. This effort was based on the NASA Design Reference Mission (DRM) for the human exploration of Mars [NASA Design Reference Mission (DRM) for Mars, Addendum 3.0, from the world wide web: http://exploration.jsc.nasa.gov/marsref/contents.html.]. The integrated design was broken into four subsystems: Water Management, Atmosphere Management, Waste Processing, and Food Supply. The process started with the derivation of top-level requirements from the DRM Additional system and subsystem level assumptions were added where clarification was needed. Candidate technologies were identified and characterized based on performance factors. Trade studies were then conducted for each subsystem. The resulting technologies were integrated into an overall design solution using mass flow relationships. The system level trade study yielded two different configurations-one for the transit to Mars and another for the surface habitat, which included in situ resource utilization. Equivalent System Mass analyses were used to compare each design against an open-loop (non-regenerable) baseline system. (C) 2003 International Astronautical Federation. Published by Elsevier Ltd.
