Abstract: AXEUMM experiments were conducted to investigate the presence/absence of jetting at the charge surface of detonating energetic materials due to the detonator employed. Experiments are conducted using gram-range spherical charges in the blast chamber at the U.S. Army Research Laboratory's Detonation Science Facility. Early-time high-speed images of the detonation waves breakout and air shock wave's early-time expansion are captured using a high-speed intensified camera. Explosively driven air shock waves are qualitatively analyzed throughout their early-time expansion. Captured images are shown to exhibit a nearly spherical air shock wave throughout early-time expansion without the presence of jetting due to the detonator.
