HYPERVELOCITY IMPACT EXPERIMENTS

R. L. Warnica, J. W. Gehring

Open publisher page 3 citations

Abstract

Abstract : This final report describes the experimental results of a program, 'Hypervelocity Impact Experiments,' to investigate the vulnerability of multiple sheet thin target assemblies to hypervelocity projectiles impacting at both normal and oblique angles. This study of penetration, perforation and spalling was conducted using an accelerated-reservoir light-gas gun to launch projectiles to velocities ranging from 5000 fps to 25,500 fps. Projectile incident angles ranged from 90 degrees (normal) to 10 degrees. Target damage was evaluated in terms of hold area, depth of penetration and affected area. Damage was correlated with impact velocity, impact angle, projectile variables, and target variables. (Author)
