Very small conical shaped charge (CSC) jets were used to initiate four different secondary explosives. The liner thicknesses varied between 0.076 and 0.127 mm. LX-13 (80% PETN and 20% SYLGARD) explosive was used to drive the conical liners to form the CSC jets. The CSC jet velocities varied between 3.6 and 6.5 mm/..mu..s. The jet tip diameters ranged between 0.041 and 1.10 mm. The explosive acceptor or target diameters were varied between 1.90 and 19.1 mm. The lateral confinement of the acceptor explosives was minimal. Relationships for critical jet initiation energy and dimensionless explosive/jet parameter as a function of initiation parameters are developed. The jet initiation data from this investigation as well as previously published data are shown to be consistent with the developed relationships. The threshold initiation parameter (jet velocity squared times jet diameter) for LX-13, PETN, PBX-9407, and TETRYL were experimentally determined to be 0.011, 0.0130, 0.041, and 0.044 cm/sup 3//..mu..s/sup 2/, respectively, for copper jets impacting bare explosive acceptors. The lower values for the LX-13 and PETN indicate these two explosives are more sensitive to shock initiation than PBX-9407 and TETRYL explosives. 14 refs., 9 figs., 6 tabs.
