Optimum Velocity Penetrators.

Abstract

Three different representations of impact data have been examined. The data were limited to tungsten projectiles impacting rolled homogeneous steel armor at 0 degree obliquity. The impact velocity range was from 900 to 4,800 m/s, and the range of length-to-diameter (L/D) ratios was from 1 to 32. The data representations were used to determine the dependence of the optimum impact velocity on the L/D ratio. For two of the functions, the optimum velocity decreased rapidly as the L/D ratio went from 1 to 5. In general, the optimum velocity did not change a great deal as the L/D ratio went from 15 to 30. The values of the optimum velocity for long rods found in the present study did not differ significantly from previously determined values. (AN)
