Impact sensitivity of binary compositions of ground solid propellants and coal

Ram-impact machine tests of the impact explosion excitation behavior of binary mixtures of coal with ballistite powder and blended propellant are conducted. It is found that, as the coal content in the mixtures is raised, their mechanical sensitivity decreases. The effect of moisture on the impact sensitivity of the mixtures is analyzed. A recommendation is given for the safest way to load the components in a mixer during the stage of preparing propellant formulas of the required composition.
