Initiation of Detonation in Composition B by an Underwater Shock Wave.
Abstract
This paper examines the interaction of underwater shock waves with bare, cylindrical Composition B acceptor charges. Suitable methods to discern detonation and non-detonation of an underwater charge were determined. Separation distances for the 50% probability of sympathetic detonation of Composition B acceptors using 0.5, 2.5, 5.0 and 10.0 kg spherical pentolite donor charges were calculated from the Bruceton technique. The variation in near field shock wave velocity between donor and acceptor charges was modelled in terms of reduced charge separation to permit an economy of effort in predictions of the effects from underwater charges of a changed scale. Measurement of shock wave transit times indicate that initiation of detonation in the acceptor is due to the underwater shock wave alone.
