Abstract:

Formulas are presented to predict the initial fragment velocities from hollow spherical and cylindrical warheads. These formulas are modified from others, which predict the initial fragment velocities from solid spherical and cylindrical warheads. The results of the new formulas are tabulated for a number of ratios of both the explosive charge to the case mass and the inner to the outer radius of the explosive charge. Results with the new formulas agree with the results obtained by using theoretical formulas and with test data.
