Underwater performance of polyurethane - PETN explosives
Source abstract
Abstract
Abstract Detonation velocities and pressures for Polyurethane Foam - PETN charges at a density of 0.6 g/cm3 have been determined experimentally and compared to theoretical predictions obtained by the TIGER code, using the BKW equation of state with the RDX fit and a new fit developed for low density explosives. It was found that the explosive exhibits a non-ideal performance at small charge diameters. In order to determine the equation of state of the detonation products of the explosive in underwater applications, aquarium experiments were conducted and compared with hydrodynamic calculations performed by the TDL code. HOM equation of state parameters were obtained by using a trial and error approach so that good agreement is observed between experimental detonation velocities and gas expansion histories underwater. Using this technique, HOM parameters were obtained in three different charge diameters. It was found that at a diameter of 70 mm the detonation behaviour of the explosive is ideal while non-ideal performance is exhibited at the smaller diameters of 19 mm and 45 mm.
