The thermochemical response of three ablative materials was evaluated for protecting a plenum exhaust system from the environments due to the firings of two different solid propellant motors. The response of silica phenolic and two asbestos phenolic materials was studied for the cases of a single step (booster only) rocket motor and a two step (booster and sustainer) rocket motor being fired at normal impingement onto two-dimensional infinite flat plates of the materials. Results are presented for both the gas flow predictions and the material ablation. (DePo)
