A series of 13 shaped charge tests was conducted. The primary objectives were to investigatesmall scale bimetallic and reactive liners and to record the target deformation characteristicsof larger scale reactive liners. Tests 1 - 9 used liners of 20.02 mm diameter and were conductedin either a containment tube that housed an array of target plates or in a large blast tankwithout target plates. The liners in tests 1 - 9 were either solid copper, solid aluminum, or abimetallic design consisting of a copper cone with an aluminum insert. The bimetallic linersshowed some light emission that indicated hydroreaction, but their depth of penetration was56% less than the solid copper liners. Peak pressures for each liner were measured in thecontainment tube at various depths. Peak pressures were also measured in the blast tankat 203 mm and 368 mm below the base of the liner. The peak pressures of the solid copperliners and the composite liners were not significantly different.Tests 10 - 13 used larger scale, 50.75 mm liners and were fired into large tanks. Test10fired a copper liner into water, tests 11 and 12 fired an aluminum liner into water witha target plate array, and test 13fired an aluminum liner into a non-reactive oil with atarget plate array. Tests 11 and 12 showed large plate deformations in the unpenetratedtarget plates, while test 13 showed very little plate deformation in unpenetrated plates. Forexample, the maximum deformation of the first unpenetrated plate in test 12 was 10.6 mmbelow its original position. The maximum deformation of the first unpenetrated plate intest 13 was 0.42 mm below its original position. An optical system was used to determinethe jet tip velocity of tests 11 - 13. Jet tip velocity varied by 14.0% across the three tests.
