A study is made of the thermal response of charring ablators to given environmental conditions. The heat protective materials considered form gases and a porous char as they undergo thermal degradation in depth. The analysis considers the transient conditions and the effect of porosity pressure on the gas pressure build-up within the porous char. The effects of porosity and permeability are included. Results of the temperature, material density, and gas pressure distribution through the heat protective layer are presented for a typical charring material. Two cases are considered in the first case, the material undergoes one degradation reaction in the second case, the material under goes two successive reactions. The inclusion of char removal can also be accomplished by this study.
