An experimental study of aluminized solid rocket propellant combustion was conducted in order to determine the influence of various propellant formulation factors on metal agglomeration, The results allowed us to determine the dependencies of the agglomeration process characteristics on the physical and mechanical properties of the propellant binder, the particle size of the metal fuel, the type of film covering the original metal particles, and the type of oxidizer in the propellant. These results, combined with earlier data, were used to develop a physical picture of the agglomeration process, which may serve as the basis for conducting analysis of the influence of various propellant formulation factors on agglomeration.
