AN APPROACH TO ABLATION MATERIALS STUDY,

Abstract

A program is presented for the systematic study and development of ablation-type thermal insula tor materials for use in both rocket propulsion systems and missile re-entry body heat shields. The goals of this program are: (a) to study the ablation phenomena in general, (b) to write empirical expressions for heat transfer in an ablating body, and (c) to develop and optimize ablation materials based upon (a) and (b). In the accomplishment of these goals, the ''alpha'' rod is proposed as the principal experimental technique by which materials will be evaluated over a wide range of environmental conditions. To provide flexibility in generating such test conditions, a gas stabilized arc heater capable of being programed through wide ranges of energy levels, pressures, chemical environments, and mass flow rates is proposed.
