Investigation into the Effects of Underwater Shock Waves on Simple Structures, Shielded and Bare Explosive Materials

Abstract

The detonation of an underwater charge creates a shock wave and a bubble of gaseous products at high temperature and pressure. At greater ranges, the shock wave and bubble become separated and their effects on structures may be studied separately. However, close to the point of detonation, in the regions typically used for sea-mine neutralisation, the shock wave and bubble lie in close proximity and their relative importance in the neutralisation process is not known. A series of scaled experiments to visualise the early development of the shock wave and bubble, and their interactions with an explosive and with simple structures were devised. These experiments used spherical pentolite charges and cylindrical Composition B charges as the donor and acceptor charges respectively. Both charges were suspended in a small, transparent water-filled tank and the effects of the exploding donor recorded by a Cordin rotating mirror camera.
