空间站轨道参数选择

该文以飞船作为天地往返运输器，从空间站轨道维持和补给所需的推进剂最少出发，对空间站轨道参数进行了优选，结果表明，当空间站质量增加时，空间站最佳运行高度应该提高，而当空间站补给次数增加时，其最佳运行高度应该下降。对８吨和１８吨空间站，补给间隔分别为３个月、半年和一年的６种方案，空间站的最佳运行高度在３７０ｋｍ至５２０ｋｍ之间。

SPACE STATION ORBIT PARAMETERS SELECTION

The optimum orbit altitude of space station,which expends the minimum propellant for orbit maintenance and supply,is studied for manned spacecraft delivery system.The numerical results showed that the orbit altitude should be adjusted upward with the increase of the space station mass and should be lower as the traffic levels to space station are increased.For 8 ton and 18 ton space station whose supply periods are three months,half a year,and one year respectively,The optimum orbit altitude of space station is between 370 km and 520 km.
