Feasibility Study of an Expandable Space Maintenance Hangar

摘要

To determine the feasibility of an expandable space hangar, a composite wall using polyester terephthalate, 181 style glass cloth, polyurethane foam, and polyvinylidene chloride is designed to operate in a 500 kilometer circular orbit. The structure is cylindrical with hemispherical ends and has a length of 65 feet and a diameter of 25 feet. The wall affords occupants protection form radiation and meteoroids, has a low gas permeability, withstands an internal pressure of 7.5 lb/sq. in., and can be compressed into a launch package of 460 cu. ft. It is concluded that a design of an expandable space hangar is feasible. (Author)
