О возможности создания крупногабаритных конструкций в условиях открытого космоса

Abstract

The paper gives a brief overview of the history of the development of inflatable space struc-tures. Further development should be the use of inflatable shells that harden in space. The possibility of using this technology in the framework of the use of simple tasks is considered in the article. On the ex-ample of thick-walled spherical and cylindrical shells, using Lame's analytical solutions, it is shown that the thickness of the shell can be thin. The thin shell design is much easier to inflate. No high pressure is required for this. Using the classical heat conduction equation, the temperature distribution inside a cy-lindrical shell is determined. When setting the boundary conditions, the flux of rays incident both from the side of the Sun and from the side of the Earth was taken into account. The radiation on the surface of the cylinder was calculated according to the Stefan-Boltzmann law. It has been established that a tem-perature occurs in the shell, the maximum value of which is in the range from 150 to 200 degrees Celsi-us. Prepreg casings require the use of a high temperature resin suitable for hot curing.
