Abstract

A series of 13 shaped charge tests was conducted. The primary objectives were to investigate small scale bimetallic and reactive liners and to record the target deformation characteristics of larger scale reactive liners. Tests 1 - 9 used liners of 20.02 mm diameter and were conducted in either a containment tube that housed an array of target plates or in a large blast tank without target plates. The liners in tests 1 - 9 were either solid copper, solid aluminum, or a bimetallic design consisting of a copper cone with an aluminum insert. The bimetallic liners showed some light emission that indicated hydroreaction, but their depth of penetration was 56% less than the solid copper liners. Peak pressures for each liner were measured in the containment tube at various depths. Peak pressures were also measured in the blast tank at 203 mm and 368 mm below the base of the liner. The peak pressures of the solid copper liners and the composite liners were not significantly different. Tests 10 - 13 used larger scale, 50.75 mm liners and were fired into large tanks. Test 10 fired a copper liner into water, tests 11 and 12 fired an aluminum liner into water with a target plate array, and test 13 fired an aluminum liner into a non-reactive oil with a target plate array. Tests 11 and 12 showed large plate deformations in the unpenetrated target plates, while test 13 showed very little plate deformation in unpenetrated plates. For example, the maximum deformation of the first unpenetrated plate in test 12 was 10.6 mm below its original position. The maximum deformation of the first unpenetrated plate in test 13 was 0.42 mm below its original position. An optical system was used to determine the jet tip velocity of tests 11 - 13. Jet tip velocity varied by 14.0% across the three tests.
