A New Thermal-Insulation and Support Concept for Extreme Environments

This paper presents an advanced thermal-insulation and structural-support concept developed at Battelle Memorial Institute. A unique, high-temperature, lightweight, metallic structure of relatively high strength is described, which is particularly suited for aerospace applications in which environmental extremes render conventional insulations inadequate. The parameters of the device, a multiple web and foil structure, are explained in detail and related to strength and insulation criteria. The relations developed are sufficiently general to allow custom designing of these two property requirements.
