层次分析法在空间推进系统综合评价中的应用

在建立航天器推进系统综合评定体系的基础上，动用层次分析法对已经应用飞行的推进系统和有未来应用潜力的推进系统进行了评估。评估结果表明，从能量特性，使用性能、系统可靠性、经济性、系统特性五个准则上看，过氧化氢／煤油无毒推进系统是未来航天器在轨推进的最优选择。

APPLICATION OF THE ANALYTIC HIERARCHY PROCESS IN THE EVALUATION OF SPACECRAFT PROPULSION SYSTEM

Based on the whole evaluation model of the spacecraft propulsion system ,several propulsion systems used at present and promising in the future are estimated by way of Analytic Hierarchy Process(AHP). The result from the trade study indicates that the Hydrogen Peroxide kerosene non toxic system is the best choice for future on orbit propulsion system of spacecraft in terms of the five interrelated study criteria such as energy behavior, character of service, system reliability, economy aspect and system feature.
