Effects of Different Size and Shaped Magnesium Particles on the Properties for Fuel Rich Solid Propellant

Abstract:

The physic-chemical characteristics of spherical and coarse magnesium particles were determined. The rheological properties of Mg/HTPB mixtures were investigated. The burning rate performance and mechanical properties of fuel rich propellant were evaluated. The results show that the spherical magnesium particles could be dispersed in the HTPB binder with lower viscosity and yield stress than those of the coarse ones. The burning rate and pressure exponent of propellant with spherical particles increased compared with the coarse ones, and the percent elongation is much higher than that of coarse one, whereas, the tensile strength shows reverse.
