The Shaped Charge Hypervelocity Projectile Accelerator is being used to study impact and penetration effects upon various thicknesses of targets at velocities between 24,000 and 39,000 feet per second. This report presents and analyzes 208 data points gathered for impacts in the 29,000-33,000 fps velocity range, with 0.03-0.8 gram aluminum projectiles against 0.375-inch, 0. 500-inch, 1.00-inch and 4.0-inch thick 2024-T4 aluminum target plates 19 data points gathered for impacts in the 35,00039,000 fps velocity range with 0.01-0.7 gram aluminum projectiles against 0.100-inch thick 2024-T4 aluminum target plates and 63 data points gathered for impacts in the 22,00026,000 fps velocity range with 0.02-0.7 gram copper projectiles against 0.100-inch thick 2024-T4 aluminum target plates and 0.500-inch thick soft copper target plates. Angles of obliquity between the velocity and the target surface for these experiments were 90, 50 and 20 degrees. Curves, photographs, and flash radiographs illustrating the data are presented.
