Research was conducted to determine the particle size distribution in the motor and exhaust of a small solid propellant rocket motor using light scattering techniques. A commercially produced MALVERN 2600 Particle Sizer was used in conjunction with a locally designed light scattering apparatus. The physical dimensions of the motor windows limited the minimum measurable particle size to roughly 3.5 microns. Motor data was repeatable and agreement between light scattering systems was within approximately 7. A large particle bias was evident. The source of this bias was believed to be the RTV used for bonding and inhibiting.
