Responses of HMX-based and PETN-based Explosives to Electrostatic Discharge

doi:10.3969/j.issn.1000-1093.2015.02.026

Abstract

Abstract: The responses of high-density HMX-based and PETN-based explosives to electrostatic discharge(ESD) are tested by JGY-50 electrostatic spark tester. Two discharge modes including impenetrating discharge and surface discharge are employed to simulate the different ESD scenarios. The results show that the response of high-density explosives include heat and shock effects. The heat effect of PETN-based explosive and the shock effect of HMX-based explosive dominate under ESDs. No detonation is probably observed because there is less accessible surface area and low permeability of high-density solid explosive allowing little convective burning, and the energy of ESD can not be coupled effectively to high-density solid explosives.

Key words: ordnance science and technology, electrostatic discharge, explosive, heat effect
