INVESTIGATION OF METEOROID IMPACT ON TWO-SHEET CONFIGURATIONS.

Abstract

Experimentally obtained perforation data are used to provide data establishing the effects of variations in the geometric parameters of two-sheet target configurations subjected to hypervelocity impacts. Aluminum alloy 5052-0 foils, 0.0051 to 0.0005 inch thick, were used to fabricate all targets. The front-sheet thickness versus perforating velocity (t-1 vs V) curves generally tend to show that perforation velocities are highest for target configurations in which the total thickness is distributed equally between the fromt and rear sheets at all spacings. The existence of an optimum configuration is evident. The consistency with which the reduced data fit parabolic curves strongly suggests that, for a constant total target thickness and spacing, the relationship between significant variations of the front sheet thickness and the perforating velocities is approximated by a parabolic law.
