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.
