Natural Missile Distributions for High Explosive Craters in Hard Rock. Volume III. Multiple Threat Cratering Experiment.
Abstract
Natural missile distributions resulting from high explosives detonated on or near the surface of basalt are analyzed for 14 events ranging in yield from 2,000 to 16,000 pounds of TNT. Spherical charges were detonated in three different coupling modes: half-buried, tangent to but above the rock surface, and tangent to but below the rock surface. Hemispherical charges were detonated on the rock surface. A computer program was developed to analyze missile distributions in terms of a number of statistical parameters for craters as a whole, linearly by 50-foot annular rings, and radially by 10-degree sectors. Statistical parameters are discussed in terms of charge-weight, coupling mode, distance from ground zero, and azimuth. Statistical parameters are also presented as functions of burst depth for charges of equal weight. Equations are derived which relate missile specific area to radial distance and burst depth. Missile size distributions are presented and correlated for relevant crater parameters. (Author)
