Inflatable unfolding stiffened lunar soil filling brick with foldable rigid shell

Abstract

The invention discloses a lunar soil filling brick provided with a foldable rigid shell and capable of being stiffened through inflation expansion, and belongs to the technical field of spacecraft structures. The lunar soil brick is of a foldable structure, small in launching size and high in strength after being formed, and in-situ manufacturing of the lunar soil brick can be carried out on the moon. The foldable lunar soil bag comprises a foldable rigid shell and a flexible lunar soil bag, the flexible lunar soil bag is arranged in the rigid shell, the rigid shell and the flexible lunar soil bag can be folded and launched, a connecting pipe is arranged on the flexible lunar soil bag, the flexible lunar soil bag is inflated through the connecting pipe by means of the inflation pump, inflation unfolding of the flexible lunar soil bag is achieved, and heating stiffening of the unfolded flexible lunar soil bag is achieved. The interior of the rigidized flexible lunar soil bag is automatically filled with lunar soil through a sand filling pump. The lunar soil filling brick is light in weight, high in structural rigidity, good in stability, good in pressure bearing performance and good in radiation protection performance, lunar soil resources can be fully utilized, and the transportation cost of lunar surface building materials is reduced.

Description

technical field [0001] The invention belongs to the technical field of spacecraft structures, in particular to an inflatable and expandable rigid lunar soil filling brick with a foldable rigid shell. Background technique [0002] The lunar base is the main place for lunar exploration astronauts to work and live on the moon. In order to reduce the transportation cost of lunar surface building materials, in situ resource construction technology (ISRU) will become the main construction plan. Lunar soil is the most important in-situ resource on the lunar surface. It can be used for building surface covering, thermal insulation, radiation protection and micrometeoroid impact protection for buildings. [0003] At present, the lunar soil brick construction technology based on lunar soil mainly includes lunar soil concrete 3D printing technology, lunar soil sintering technology, lunar soil bonding technology, lunar soil bag confinement technology, etc. Among them, the main difficul...
