The invention discloses an inflatable unfolding semi-rigid sealed cabin adopting a compressible multi-layer sandwich protective layer, and belongs to the technical field of spacecraft structures. The sealed cabin comprises a sealed pressure-bearing inner bag, a space environment protection layer, an auxiliary unfolding multi-stage sleeve and two rigid sealing heads, the sealing head edges of the two rigid sealing heads are connected with the sealed pressure-bearing inner bag and the space environment protection layer, the centers of the two rigid sealing heads are connected with the auxiliary unfolding multi-stage sleeve, and the sealed pressure-bearing inner bag is arranged in the space environment protection layer. The sealed cabin is composed of rigid multi-layer sandwich modules, the modules are connected through flexible strips and are folded in an overlapping mode, and the problems that the inflatable cabin is difficult to fold due to the fact that the cabin wall is too thick, the unfolding friction force after folding is large, the unfolding control difficulty is large, and material folding damage is likely to be caused are solved. The rigid multi-layer sandwich module can be further compressed after being folded, the compression rate is high, the folding size of the sealed cabin can be further reduced, and the problem that a thick-wall inflatable cabin is large in size after being folded is solved.

    一种采用可压缩多层夹芯防护层的充气展开半刚性密封舱,属于航天器结构技术领域。该密封舱,包括密封承压内囊、空间环境防护层、辅助展开多级套筒及两个刚性封头,两个刚性封头的封头边缘之间与密封承压内囊和空间环境防护层连接,两个刚性封头中心处与辅助展开多级套筒连接,所述密封承压内囊设置在空间环境防护层内部。本发明由刚性多层夹芯模块构成,模块间由柔性条带连接,并采用叠合方式折叠,解决了充气舱由于舱壁太厚造成的难以折叠,折叠后展开摩擦力大、展开控制难度大,及易造成材料折叠损伤等问题。刚性多层夹芯模块折叠后可进一步压缩、压缩率高,可进一步减小密封舱的折叠体积,解决了厚壁充气舱折叠后体积较大的问题。
