Thermal insulation for use under conditions of reduced gravitational field

摘要

Especially designed for zones of pressurized atmosphere in space vehicles and stations where the phenomenon of convection of the air originating from the variation in density thereof as a function of temperature is not present, it consists of two parallel walls 1-1' between which there is a space 3 containing confined air acting as actual thermal insulator, the aforesaid walls 1-1' being lagged both on their inner face and on their outer face with a layer of a material which is highly efficient at reflecting infrared radiation. To this end, each wall 1-1' may be embodied as a thin sheet of polyimide or polyester with its faces having been given a covering 2 based on aluminium coating by means of deposition. IMAGE
