Abstract: |
In view of the advantages and disadvantages of the high reliable sealing technology of the extraterrestrial sampling device, combined with the achievements of space electron beam welding technology, three welding working modes of sampling device are proposed: man-machine cooperation, personnel autonomy and equipment automation. The difficulty and adaptability requirements for each mode are analyzed. Combined with the development trend of multiple target and multi task, some suggestions for the later development of space electron beam are put forward. |
