Propellant formulation factors and metal agglomeration in combustion of aluminized solid rocket propellant

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