Title: Internal sub-sonic burning during an explosion viewed via dynamic X-ray radiography

Abstract

In this study, we observe internal convective and conductive burn front propagation and solid consumption subsequent to thermal ignition for plastic bonded formulations of the solid organic secondary explosives octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine and 1,3,5-triamino-2,4,6-trinitrobenzene. This work describes x-ray radiographic diagnostics enabling the study of solid density in a fully encased explosive during internal burning subsequent to ignition. Finally, the result of this study is the ability to directly observe and measure rates of energy release during a thermal explosion.
