Sealed cabin wall structure of manned spacecraft

Abstract

The invention relates to a sealed cabin wall structure of a manned spacecraft. The sealed cabin wall structure comprises a first partition plate (1), a first dot matrix layer (2), a second dot matrixlayer (3) and a third partition plate (4) which are sequentially arranged; the first dot matrix layer (2) and the second dot matrix layer (3) are both composed of tightly arranged cell structures (6);the sealed cabin wall structure further comprises a second separation plate (5), and the second partition plate (5) is positioned between the first dot matrix layer (2) and the second dot matrix layer (3); the size of a single cell structure (6) forming the first dot matrix layer (2) is smaller than that of a single cell structure (6) forming the second dot matrix layer (3); and the thickness ofthe first dot matrix layer (2) is larger than that of the second dot matrix layer (3). The cabin wall structure integrates multiple functions, and the requirements for weight reduction and efficiencyimprovement of spacecraft design are met.

Description

technical field [0001] The invention relates to the field of spacecraft, in particular to a bulkhead structure of a sealed compartment of a manned spacecraft. Background technique [0002] Manned deep space exploration is the development trend of future aerospace technology, which puts forward higher and more stringent requirements for the design of future spacecraft for weight reduction and efficiency enhancement. At present, the main structure and auxiliary structure of the spacecraft mainly involve functions such as sealing and maintaining pressure, carrying launch loads, micrometeoroid impact protection, and heat insulation. However, each structure is independent of each other, and has a single function, and the design of each functional load-bearing structure is repeated, resulting in a large structural weight redundancy. Contents of the invention [0003] The purpose of the present invention is to provide a manned spacecraft airtight cabin bulkhead structure that co...
