A double-layer bulkhead type inflatable cabin

Abstract

The invention provides a dual-layer cabin wall type inflation cabin body. A manned cabin body comprises an inner bag and an outer protecting shell, wherein the inner bag is arranged in the outer protecting shell; a fragment cloud ball space is arranged between the inner bag and the outer protecting shell; an inflation supporting frame is arranged in the fragment cloud ball space; the bag wall of the inner bag consists of an airtight layer and a bearing layer, the airtight layer is the innermost layer of the bag wall, and the bearing layer is positioned on the outer side of the airtight layer; the bag wall of the outer protecting shell consists of an airtight layer and a stiffening layer, the airtight layer is the innermost layer of the outer protecting shell, and the stiffening layer is the outermost layer of the outer protecting shell. The cabin body is high in folding efficiency, small in emitting size and light in weight; the inner bag and the outer protecting shell are connected through the inflation supporting frame to form a space with a certain distance, so that transfer and a convection effect between inner heat and outer heat of the inflation cabin body are baffled, the heat isolation effect of the cabin body is effectively improved, a protecting structure similar to a Wyeth shield is formed for the dual-layer inflation cabin body, and the space fragment preventing and protecting efficiency of the inflation cabin body is effectively improved.

Description

technical field [0001] The invention relates to a double-layer bulkhead type inflatable cabin, which belongs to the technical field of aerospace cabins. Background technique [0002] Space cabins (such as living cabins, experimental cabins, instrument cabins, or airlock cabins, etc.) are the main places where humans work and live on space stations or planetary bases. Future space stations, manned moon landings, and lunar bases need to have an inner diameter of several meters. Even large airtight cabins over tens of meters. Existing space cabins are mainly rigid metal cabin structures. Space cabins using rigid metal structures are heavy in weight, large in volume, high in launch cost, difficult in launch, and difficult to meet the needs of space stations, manned moon landings or lunar bases. The demand for large space cabins, in order to improve the environmental protection capability of the cabin space, some auxiliary structures or protective materials need to be added to t...
