Radiographic Studies and Hydrocode Simulations of Two Tantalum EFPs (Explosively Formed Penetrators).

摘要

The Army Research Development and Engineering Center (ARDEC) commissioned Los Alamos to provide Honeywell, Inc. with one high- energy flash radiograph for each of two explosively formed penetrators (EFPs) of tantalum. The two axisymmetric warheads were identical in their basic design, but their liner contours were different. The first shot, which we designate as H853, used Honeywell's liner design number 1; the second shot, H854, used design number 2. The experiments were planned and directed by J. M. Christian (M-4) and were performed at the Ector radiographic facility (R-306) during the weak of February 22, 1988. Data reduction and analyses were accomplished over the next several months by K. H. Mueller, Jr. (M-4) and L. A. Schwalbe (X-3). In addition to the experimental work, the computations group (X-3) offered to run hydrodynamic code simulations of the EFP formation for the two designs. Some of the results and conclusions of this theoretical work are also presented below. 5 refs., 7 figs. (ERA citation 14:000894)
