ABSTRACT:
A high temperature multi-layer thermal insulation is constructed especially for insulating spacecraft. For this purpose the insulation is formed of a plurality of porous material layers, such as ceramic fiber layers, separated from each other by highly reflective gas permeable foils. The insulation has an outer hot side and an inner cold side. The ceramic fibers are so arranged that the layer density increases from the outer side toward the inner side while the fiber diameter decreases from the outer side to the inner side. Compared to conventional heat shield type insulations of spacecraft, the present insulation is relatively lightweight and is able to better discharge again at lower flight altitudes any heat stored in the insulation at higher transient re-entry altitudes.
