The results are presented from research concerned with determining the mechanisms governing formation and subsequent combustion of metalagglomerate particles throughout an aluminized solid rocket motor. Of primary concern is the influence these particles have on propellant combustion characteristics and overall motor performance. The approach taken involves making use of a laboratory scale, servo-controlled strand window bomb in conjunction with both an imaging-type, particle size analzyer and a pulse-lit photographic technique. In this paper, the servo-controlled strand window bomb is briefly described. The theory and operation of the imaging-type, particle size analyzer to be employed is detailed. Finally, the feasibility of using pulse-lit photography within a study of particleagglomerate combustion is discussed along with the presentation of such photographs taken.
