Abstract
A heat-resistive wall assembly for a space vehicle is disclosed herein comprising an inner wall formed from either wrought beryllium or aluminum for providing both structural support for the vehicle, as well as a heat sink which equilibrates the heat gradient around the vehicle during reentry, an outer wall preferably formed from interlocking panels of a honeycomb laminate of a heat resistive metal such as Inconel.RTM. 617, and an evacuated jacket formed from an envelope of nickel foil which is disposed between the inner and outer walls. The evacuated jacket contains an insulating material formed from alternating layers of a sheet material made from nonwoven quartz fibers, and sheets of nickel foil. Even though the interior of the wall assembly is exposed to ambient atmospheric pressure, such atmospheric pressure is insufficient to compress the evacuated jacket during the maximum heat experienced by the vehicle during reentry into the atmosphere. Thus the evacuated jacket maintains an expanded heat flux retarding position when the heat load upon the vehicle wall assembly is at its highest.
