Hypervelocity Impacts into Stainless-Steel Tubes Armored with Reinforced Beryllium
Abstract
Tubular stainless-steel targets armored with three types of internally reinforced beryllium were impacted with hypervelocity projectiles to determine the cratering behavior and the relative effectiveness of the reinforcements in reducing external cracking damage. The three methods used to internally reinforce the armor were compartmentation, concentric rings of mesh, and randomly oriented, uniformly dispersed filaments. A light-gas gun was used to accelerate 3/32-inch-diameter Pyrex spheres to a nominal impact velocity of 24 000 feet per second. The tubular beryllium targets were maintained at a temperature of 1300 deg F during impact. Measurements of the craters, descriptions of the total damage, and photographs of the tubes are presented, and comparisons are made with previously reported damage to comparable homogeneous beryllium armored targets. Impacts on the reinforced-armor targets, which were heavier per unit length than the unreinforced-armor targets, showed little reduction in the external cracking damage in the armor compared with the unreinforced-armor targets.
