A simple method for estimating radiative heating by the plumes of solid rockets was developed. Plume shapes were approximated as bisected conical cylinders with an apex angle. Similarities in the plume shape, the size of plumes, and the distribution of radiative power are shown between subscale motors and the solid rocket boosters (SRB) of space shuttles. All radiation is assumed to be emitted from the surface of the cylinder. The effects of the interior of the plumes is confined to the emissivity of the surface. The emissivity of the plume can be related to its optical thickness, and the optical thickness can be estimated from the number density and the diameter of particles in the plume. Dependence of radiative heating on motor size and flight altitude can be explained in terms of similarities in plume radiation.
