Fragmentation Characteristics of Horizontally Stacked Bombs
Abstract
The FRAGHAZ Computer Program1 was developed by the Naval Surface Warfare Center (NSWC/Dahlgren) for the Department of Defense Explosives Safety Board (DDESB). The primary purpose of the program was to provide a means for estimating the fragment hazards to personnel from the inadvertent detonation of stacks of stored munitions. The Computer Program is primarily a Monte-Carlo type incorporating the capability of statistically handling a number of uncertain variables. The model relies on small-scale fragmentation arena tests to provide the fragment data for full-scale ammo stack investigations. Each fi-agment recovenxi from the test, greater than a specified minimum weight, forms the basis for a trajectory which is calculated in its entirety using a fourth order Runge-Kutta routine. The intersection of the hgment tmjectory with a hazard volume (a pie-shaped volume with an angular width, usually 10 degrees or less, and a height equal to the target height) provides the means for calculating the fragment hazard to the target in terms of density and probability of hit. Since we calculate the entire trajectory, we know both the static and dynamic characteristics of the fragment at all ranges where the trajectory intersects the hazard volume. The target is assumed to be randomly located within the hazard volume and the hazard volume ranges are normally divided into 100 feet increments.
