Test Results of Earth Penetrators
Abstract
Three test series were conducted to observe the stability of small length-to-diameter ratio projectiles penetrating natural earth and concrete clad earth targets. Impact velocities were from 1300 ft/sec to 2000 ft/sec. A wide variety of projectile shapes were found to penetrate stability at a variety of angles-of-attack (yaw) and at impact obliquities of zero and twenty degrees. A self-obturating sabot was developed which launched projectiles at reproducible velocities but with an unpredictable angular velocity.
