Abstract

The objective of the study is to validate and advance the understanding of the Matrix detonating cord charge. This paper examines the functionality of the Matrix charge and compares the propagation and shock wave behavior to sheet explosive charges (deta-sheet). This was achieved through a series of tests in which the charges were detonated underwater in an aquarium and observed with ultra high speed imaging instrumentation. The team successfully recorded and documented various detonation events involving simple and complex charge geometries. The data enabled the team to measure velocity of detonation (VOD) values, analyze shock front propagation and analyze shockwave interaction. Tests results show that the sheet explosive produces a symmetrical and uniform incident shock wave, and the Matrix charge produces multiple incident shock waves, which collide and reflect, and generate Mach stem waves.
