UNDERWATER EXPLODING WIRES.
Abstract
The report treats: (1) the shock wave parameters associated with exploding wire phenomena (EWP) under water and (2) their comparison to TNT data. The assumptions, correction factors, and justifications central to the data reduction and analysis are outlined. The equivalent weight of TNT represented by the energy stored in a capacitor is established and justified. In terms of weight, the law of similarity is extended six decades to micropounds. An explosion constant for very rapid, small amplitude explosions is defined. The shock wave parameters of peak pressure and reduced time constant for EWP are found to form similarity curves and are given by the empirical relations: P sub m = 21400 (W to the 1/3 power/R) to the 0.99 power; tau sub e/W to the 1/3 power = 57 (W to the 1/3 power/R) to the minus 0.31 power.
