Half-Scale Tests for Containment of a Fragmenting Projectile
Abstract
An accelerated program was conducted to evaluate design ideas and to predict performance of a vessel to contain the detonation of a heavily confined high explosive projectile. Several design ideas were examined using 1/2-scale open-ended cylinders. It was demonstrated, using available off-the-shelf components, that two concentric steel cylinders (one about 10% smaller than the other) lined on the inner surface with a fiberglass cylinder (to slow fragments) could contain a 4540-g equivalent case charge in the full scale. When the outer steel cylinder was wire wrapped with high tensile strength wire the full-scale capacity increased to a 7260 g equivalent cased charge. The effect of adding metal honeycomb or metal foam between the steel cylinders was also examined and found to reduce the maximum strain on the outer cylinder.
