  • The linear shaped charge is designed to produce a knife blade-like flat jet, which will perforate and sever one side of a modestly hard target from the other. This charge is approximately plane wave initiated and used a water pipe quality circular copper liner. To establish the quality of this jet we report about an experiment using several of the Lawrence Livermore National Laboratory high-resolution diagnostics previously published in this meeting [1]. Image converter tube camera stereo image pairs were obtained early in the jet formation process. Individual IC images were taken just after the perforation of a thin steelmore » plate. These pictures are augmented with 70 mm format rotating mirror framing images, orthogonal 450 KeV flash radiograph pairs, and arrival time switches (velocity traps) positioned along the length of the jet edge. We have confirmed that linear shaped charges are subject to the same need for high quality copper as any other metal jetting device.« less
  • Experimental data on the jet characteristics and penetration performance of four 150 and four 220 grain per foot linear shaped charges are presented. The predictions from an analytical code developed to model the three dimensional collapse, jetting and penetration process of linear shaped charges compare favorably with the experimental data. 7 refs., 9 figs., 2 tabs.
  • The microstructures of two soft-caught copper shaped charge jet particles were investigated. In particular, the spatial distributions of crystallographic texture within the particles were characterized using point specific measurements of crystallographic orientation. Significant variations in preferred orientation were observed. These results are discussed in fight of previous computer simulations of the jetting process which showed significant radial gradients in both strain and strain rate.
  • A Conical Shaped Charged (CSC) is an explosive assembly used as a single point penetrator in applications ranging from commercial to national defense. The formation, flight characteristics, and penetration effects of the CSC are of great importance to its users. Because of the extreme velocities of the shaped charge jet, high speed documentation was necessary to research CSC effects. By use of closure switches and initial velocity studies, framing and lighting information for the Cordin 114 Ultra High Speed camera was determined. After the initial data were gathered, it was determined that another source of documentation was necessary. A Hewlettmore » Packard 150 kilovolt flash x-ray system was implemented, enabling more accurate velocity measurements and a better understanding of jet formation and the CSC during flight. Both techniques of documentation were invaluable in the characterization and research of the conical shaped charge.« less
  • The Linear Explosive Shaped Charge Analysis (LESCA) code is used to analytically model and optimize the design of a linear shaped charge (LSC). A variety of LSCs are initially modeled with the LESCA code, and the predicted jet penetration versus standoff data are compared to experimental data. The LSCs varied in explosive loading size form 600 to 10,500 grains per foot. The LSC liner material for this study was cooper. The variables optimized in this study included the LSC apex angle, liner thickness, explosive width, and explosive width, and explosive height. 8 ref., 24 figs.
