This paper presents a brief review of the limited number of research efforts conducted over the past decade devoted to the application of both observed and theorized aluminum particle agglomeration, ignition, and combustion behavior into the framework of a theoretical combustion model for heterogeneous, composite solid propellants.This review clearly demonstrates the need for the continuation of such a modeling effort. In this light, the statistically-based Petite-Ensemble Model (PEM) is continually beinG modified ' to account for the behavior of al umi nurn particles, especially the surface/near surface agglomeration process, with its multiple flame modeling framework.Also, experimental methodologies necessary to observe aluminum particle agglomeration, ignition and combustion behavior are detailed.These include the design, fabrication and operation of a servopositioning, strand window bomb and the analysis and feasibility study of employing high speed flash photographic techniques in propellant surface and aluminum combustion studies.
