The Foulness multiton air blast simulator. Part 3: Blast wave formation and methods used to drive the simulator
Abstract
The mechanisms by which blast waves are generated by a helical charge of detonating fuse in a 4.9 m diameter nuclear air blast simulator were studied in order to achieve control over the waveform produced. The problem of producing low pressure blast waves with long duration was overcome by immersing the charge in an aqueous foam in the firing chamber. A comparison is made with pressure-time profiles of a 1 kton nuclear shot, concluding that an accurate simulation involves a combination of techniques rather than the simple firing of an axially placed charge.
