As part of a study of the material survivability during constant-heat-flux irradiation, the effects of thermal radiation and convection during constant-heat-flux irradiation of solid surfaces were studied using equations for thin-wall and semiinfinite wall transient response cases. The results demonstrate that first-order reradiative/convective cooling effects on material survivability, and resulting exposure time enhancement and material thickness reduction, are uniquely can be completely quantified by a set of three nondimensional parameters. 13 refs.
