DIRECTIONAL EFFECT OF CHARGE MOTION ON SHOCK FORMATION AT A SPHERICAL PENTOLITE CHARGE,

Abstract

The peak pressure at interaction of the explosive and ballistic shock in the direction of charge motion is estimated from hydrodynamic theory. Approximations to the flow conditions and shock propagation along this direction are made. The increase in peak pressure at the forward point of the ballistic shock varies from about 30% at charge velocity Mach 1.5 to about 150% at Mach 10. Comparison of differing approximations in dicates that the major part of the increase results from pressure and entropy change within the ballistic shock rather than from the air flow about the charge.
