DETONATION OF A HIGHLY DILUTED EXPLOSIVE

Detonation of mixtures of PETN with quartz sand with a 10-30% content of the explosive was investigated experimentally. Such systems are cha racterized by a low pressure and detonation velocity. The mass velocit ies of the solid filler and gas of the detonation products were measur ed by the electromagnetic method. With an explosive content of more th an 15% the process is carried out by the leading shock wave and on the whole is single-velocity. The effects of a two-phase state are substa ntial with a low explosive content.
