DESIGN AND TESTING OF ABLATION MODELS WITH CONTROLLED PRESSURE GRADIENTS

Abstract

Studies of high-pressure ablation mechanisms have been hampered by lack of suitable ablation models. A technique has been developed to contour wedge models for testing in the wave superheater to give either a constant pressure, a constant heat transfer, or a constant pressure gradient up to the limit of the facility. Preliminary testing with a standard carbon phenolic composite shows that high recession rates occur even in the absence of a significant pressure gradient.
