A theoretical study of stagnation-point ablation

Leonard Roberts
SEP 1958

A simplified analysis is made of the shielding mechanism which reduces the stagnation-point heat transfer when ablation takes place at the surface. The ablation process considered is that in which the material changes directly from the solid to the gaseous state. The automatic shielding mechanism is discussed and the significant thermal properties of a good ablation material are given. The results of the analysis are given in terms of dimensionless parameters.
