Title: Analysis of test data on ablation of SNAP 2/10A fuel, aluminum, and stainless steel in an arc-heated wind tunnel

Abstract

A series of arc-jet tests were performed for the purpose of investigating the behavior of SNAP 2/10A fuel in a simulated reentry environment. The data from the tests (motion pictures and transient temperature distributions) were analyzed and compared with computations which used an energy balance to describe the heating of the fuel to its melting temperature. The dissociation of hydrogen was assumed to occur as an isothermal, endothermic phase change. This concept neglects the kinetics of diffusion. (A computational model incorporating these kinetics was being developed concurrently with the test.) A temperature of 2000/sup 0/F was assumed for the dissociation phase change and an alternate temperature of 1800/sup 0/F for comparative purposes.
