INFLUENCE OF ELECTRICAL FIELDS ON SHOCK OF DETONATION TRANSITION

Abstract

The prediction that one should be able to influence detonations in condensed explosives as well as gaseous ones by means of axial electric fields is studied by means of the deflagration to detonation transition (DDT) in a modified card gap (or SPHF plate) test by observing the influence of an applied field on the distance S2 into the receptor where the DDT occurs. This distance S2 for Composition B was shown to be appreciably influenced by an applied electrical field. The magnitude of the effect in 2 in. diameter cast Composition B (donor and receptor) and nearly a 5 cm lucite SPHF plate was about 0.15mm/KV/ cm, a positive to negative potential increasing the distance S2 and a negative to positive one decreasing S2 (unless the DDT occurs too close to an electrode).
