Abstract
This paper describes a computer model of Teflon ablation. The model is constructed from simplified theories and utilizes an existing numerical analysis computer program. The model is used to predict both mass loss and temperature variations during and following aerothermic heating, either in ground-based facilities or in atmospheric flight. Full dense and partial dense Teflons are modeled. Predicted results are verified with available experimental data. The model is used to design a 30% dense heat shield for the base of a typical re-entry vehicle.
