Experiments of Initiation of Covered, but Unconfined HE Charges under different test conditions by shaped charge jets

Abstract

AbstractThe initiation behavior of TNT/RDX 35/65 high explosive charges under the impact of the jet from a 44 mm diameter shaped charge with 7.8 mm/m̈s jet tip velocity, which has previously perforated a 100 mm thick barrier is reported. In these tests, the high explosive charge under test was divided into different sections by transverse air gaps, with the first section being in contact with the barrier, or the 100 mm thick barrier was sub‐divided in such a way that one part of it was in contact with the high explosive charge under test, or various air gaps, ranging from 0.5 mm to 450 mm, were made between the acceptor charge and the barrier.
