Analytical Determination of the Effect of Thermal Property Variations on the Performance of a Charring Ablator.

Abstract

An analytical investigation of the effects of varying certain material properties on the performance of a charring ablator material has been made. The quantities which are varied are char conductivity, conductivity and specific heat of the uncharred material, heat of pyrolysis, temperature of pyrolysis, and the specific heat of the gases of pyrolysis. The effects of these variations on surface recession, charred-uncharred interface recession, and internal temperature histories are shown. The analytical results are compared with experimental results and representative material property values are found which provide good agreement.
