EVALUATION OF THERMAL PROTECTION MATERIALS FOR LIFTING AND BALLISTIC RE- ENTRY HEAT SHIELD MATERIALS

Abstract

This report presents test data obtained in a hyperthermal plasma arc environment on newly-developed materials and materials concepts applicable to re-entry heat shield design including both ballistic and lifting re-entry vehicles. The experimental work concentrated on evaluation of candidate materials in the categories of (1) Low-Density Ablators, (2) High-Density ablators, (3) Special Class Low-Density Ablators for Lockheed ENCAP Program, (4) Coated Refractory Metals, (5) Graphitic Materials and Carbon Composites, (6) Char Layer Formation on Phenolic-Carbon. In addition to the materials evaluation portion of this study, a secondary objective of this project was directed toward the development of a graphical method for correlating test data. Various correlation procedures are investigated and a method using the transfer parameter of q(square root of p) is described and used for presenting test data obtained from the materials evaluated under this contract. Correlation of data and projections from accumulated data has thus far been successful for the various materials attempted.
