Paper Abstract

In order to accurately predict the performance of a kinetic energy (KE) penetrator against an oblique target plate, a clear understanding of the interaction between the penetrator and target is required. Critical to the analysis and the formulation of any theory to predict this interaction is the accurate measurement of the rate of change of the penetrator's length, mass, and yaw angle during penetration and immediately following its exit from the plate. An experimental technique was adopted in which flash radiography was used to measure penetrator characteristics as a function of time. This paper presents the conventional experimental technique, the improved experimental technique, and four test arrangement considerations associated with the multiple image radiography of a single penetrator. A limited number of quarter scale experiments of tungsten rod penetrators versus one inch aluminum (7075-T6) plates at 60° obliquity were performed and analyzed using the improved technique. Flash radiography was used to capture multiple images of the residual penetrator over a 100 OKs time window after it fully perforated the target plate. This data will be used to develop new predictive equations for rod penetration.
