基于在轨加注站的空间运输系统规模分析

Scale Analysis of Space Transportation System Supported by Space Propellant Depots

针对基于在轨加注站模式的空间运输系统,分析了其执行地球空间任务、载人月球探测任务、载人小行星探测任务和载人火星探测任务时采用的不同空间运输系统组合,对比了反推减速和气动减速两种方式,得到了具体的加注站及其空间运输系统的规模和数量需求。结果表明基于在轨加注站的整个空间运输系统规模和在轨加注规模有限,数量可控,可实现性强,利用两个加注站和有限数量的空间转移运载器就能满足多种空间探测任务的需求。

The exploration architecture supported by space propellant depots is quite promising for future routine human space exploration missions. After analyzing the space exploration mission model and the space transportation system infrastructure supported by depots,the specific propellant refueling mass and the space transportation system mass were studied in detail for the human GEO mission,the human lunar mission,the human asteroid mission and the human Mars mission. Different transportation system combinations were adopted for different space missions,and the methods of aero-brake and propulsion-brake were compared. The results showed that the refueling scales and space transportation system scales were limited and practicable. Two depots and some corresponding space vehicles could meet many future routine space missions.
