Effects of Constrictions on Blast-Hazard Areas
Abstract
A series of model tests were conducted with small-scale steel magazines to study the blast reduction effectiveness of constrictions placed in the access tunnel of underground ammunition storage magazines. We changed the loading density of storage chamber, location and number of constrictions. We measured side-on pressures in the free field as well as in the access tunnel. Constriction is very effective in reducing peak pressure and, consequently, blast hazard area within the range of our tests, and seems to be effective in reducing impulse in the free field. The double-constriction magazine was the most effective one in reducing hazard area among the magazines tested in this study, but was not the most effective one for reduction of impulse.
