Problems solved by technology

The skin structure proposed in this patent only solves the problems of airtightness, pressure resistance and anti-aging, but it cannot be directly applied in the space environment
[0005] The document "Design of Inflatable Space Capsule and Its Protective Structure" in No. 1, 2002 of "Missile and Space Vehicle Technology" introduces that the inflatable space The radiation layer only introduces the composition of each functional layer, and does not demonstrate and analyze the sequence design of each functional layer, nor can it fully meet the requirements of the manned environment.

Embodiment Construction

[0031] Such as figure 1 As shown, a space multifunctional inflatable airtight cabin skin structure suitable for a manned environment of the present invention is composed of six functional structures.

[0032] The innermost layer 1 is the wear-resistant layer and the radiation protection layer 2. A coated fiber fabric material with a certain strength is selected, which can not only protect the airtight layer from the risk of wear and scratches, but also directly protect the airtight layer on the wear-resistant layer. Radiation coating treatment has the effect of radiation protection. Such as figure 2 As shown, the outer surface of the wear-resistant layer 1 facing the airtight cabin is coated with a radiation-resistant material coating, and the radiation-resistant material coating serves as the radiation protection layer 2 .

[0033] The wear-resistant layer 1 is a plain weave structure, specifically aramid fabric or Vectran fabric, which can effectively avoid accidental dam...

Abstract

A space multifunctional inflatable airtight cabin skin structure suitable for a manned environment, comprising: a wear-resistant layer, a radiation protection layer, an airtight layer, a pressure-bearing layer, a fragment protection layer, Heat insulation layer, anti-space environment layer and flame retardant layer. The present invention adopts a technical means composed of fully flexible materials for the structure of the airtight cabin, and through the optimized configuration and design of multi-layer materials with different functions, it plays the roles of airtightness, pressure bearing and protection for the cabin structure, and brings the airtight cabin Light weight, small folding volume and other effects can directly guide the design of the structure of the compressible and foldable inflatable expandable manned airtight cabin.

Description

technical field [0001] The invention relates to a space multifunctional inflatable airtight cabin skin structure suitable for a manned environment, and is particularly suitable for an inflatable airtight cabin used for personnel living in a space environment. Background technique [0002] The inflatable structure has the advantages of light weight, high folding efficiency, and reliable unfolding. It has broad application prospects in the space field, especially with the future engineering needs of large space living quarters and manned lunar bases. The demand for inflatable airtight cabins is particularly high. protrude. However, the skin structure of the inflatable airtight cabin used in space must not only meet the basic functional requirements such as airtightness, pressure bearing, and thermal control, but also meet the safety requirements of anti-space debris impact, anti-space environmental radiation, anti-damage, and flame retardant. sexual demands.
