Abstract
Research was conducted to determine particle sizes across the nozzle of a small solid propellant rocket motor. Particle size was determined using light scattering techniques . The present optical components limit the lower measurable particle size to approximately three microns. During the investigation, spurious light was detected in the motor optical path. It was determined that transient pressure gradients in the motor during motor pressure rise resulted in deflection of the laser beam. Neutral burning propellant grains were shown to eliminate most of the observed difficulty. The use of a ring array in place of the linear array in the motor cavity measurement system is suggested for system improvement.
