THE IMPACT OF THIN DISKS INTO SEMI-INFINITE ALUMINUM TARGETS

Abstract

Hypervelocity impact tests have been performed using aluminum targets and projectiles comprising low-fineness-ratio disks (lambda/d from 0.1 to 1.0) of 1100-0 aluminum, commercially pure titanium, mild steel, and Kennertium (97. 6% tungsten). To ensure the desired projectile attitudes upon impact, rifled launch tubes were used to produce spin stabilization. These tubes allowed the establishment of the desired projectile orientation (their planar sabot without a mechanical stripping device. Cratering data for impact velocities from 11,300 to 26,200 fps indicate that the steady-state stage of hypervelocity impact of disks is important and that steady-state duration times of at least 6 microsec are significant.
