Abstract
The effect of projectile shape on thin target perforation was investigated for five projectile shapes impacting aluminum and steel targets at 506 m/sec. A discarding sabot technique was developed for launching the unjacketed steel projectiles and accurate perforation velocity losses were measured using a ballistic pendulum with the targets mounted in the center of the pendulum. The five projectile shapes included two pointed ogives, a shape similar to a Russian 14.5 mm AP core, a cylinder and a cone. The two ogive shapes were the most efficient penetrators while the velocity loss of the Russian projectile averaged 15% higher. The cone, which caused a combined petaling and plugging target failure, was the least effective shape. Calculations with two approximate perforation theories predicted smaller velocity losses than were found experimentally.Keywords
