Abstract:

Research was performed on the thermal-physical parameters of materials necessary for protection against intense thermal radiation. In the theoretical studies, a simplified model of the fabric-skin system was chosen and the heat flow equations were solved using an explicit finite difference calculation procedure programmed for solution on a Control Data G-15D digital computer. Several sample calculations were compared with results existing in the literature and a limited parameter study was performed with variation of the fabric surface heat transfer coefficients. Fabric test samples were irradiated in an arc image furnace test facility and the heating and degradation processes were qualitatively and quantitatively studied with a Mach-Zehnder interferometer. This instrument provided fabric surface temperature data, heat transfer coefficient information, and a better insight into the chemical processes taking place.
