Research on Maintenance Chain System Construction and Maintenance Strategy of Space-based Aerospace Equipment
At present,maintenance of space-based aerospace equipment is a big problem in China and even in the world.It is urgent to change the traditional maintenance mode,and establish a maintenance chain of space-based aerospace equipment,which could adapt to the on-orbit layout of space-based aerospace equipment and the development of space mission.On the basis of analyzing the necessity,feasibility and maintenance characteristics of on-orbit maintenance,the space-based aerospace equipment maintenance chain system architecture with space control center,maintenance demand node,maintenance guarantee node and material storage and supply node as key nodes was proposed by distinguishing four space heights of ground,low orbit,high orbit and deep space.The maintenance strategies of space-based aerospace equipment based on the maintenance chain at three important orbital altitudes of low orbit,high orbit,and deep space were studied.In order to improve the maintenance capability of space-based aerospace equipment and build an efficient,agile and stable maintenance chain of space-based aerospace equipment and,a design idea was put forward.
