An experimental investigation was conducted to determine the feasibility of introducing particles of a known mean diameter into a small solid propellant rocket motor and measuring the change in mean diameter across the exhaust nozzle. Light scattering profiles at small forward angles were recorded at the entrance and exit of the nozzle. The propellant utilized was nonmetallized and contained HTPB and ammonium perchlorate. Promising results were obtained for injections of polydispersions of glass beads and aluminum oxide particles.
