A simple system for two-point parallel initiation of explosive

Abstract

A simultaneous initiation of an explosive charge from two or more points can generate a localized increase in pressure, and other detonation parameters, in relation to the stable detonation of the used explosive. To achieve this increase in parameters, more or less complex initiation system has to be utilized. This paper presents a simple and inexpensive system for a simultaneous and parallel two-point initiation of an explosive charge. This system consists of a primary explosive - initiator and an attenuator made of polyetilene with two cylindrical channels - initiation points, filled with plastic explosive. The channels were placed at 24 mm distance from each other, but any distance can be used. The experiments confirmed that a simultaneous initiation was achieved.
