Available in PDF, EPUB and Kindle. Book excerpt: Crater measurements from approximately 1800 shots in more than 20 media with charge weights ranging from less than 1 lb to 320,000 lb were analyzed to: (a) gain a better understanding of the problems involved in determining the shape and size of craters formed by high explosives; (b) establish the order of variation that characterizes cratering data; and (3) develop improved and/or more generalized techniques for predicting crater dimensions. Scaling trends for shots fired on or under the ground are determined from plots of crater radius and depth as a function of charge weight. By means of the least-squares procedure, the equation of the line best fitting the data was determined, along with 95% confidence limits, thereby establishing empirically the scaling laws that relate crater size and charge weight. The well-known cube-root scaling law is not entirely acceptable for scaling all dimensions of a crater; apparently this law varies with the type of medium being cratered and the charge weight and position. Curves are presented to assist in predicting crater size and shape for charges up to 1,000,000 lb of TNT. Also, the influence of various soil types on crater size is shown graphically.

Download or read book High explosive Ditching from Linear Charges written by R. H. Carlson and published by . This book was released on 1960 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weights of linear high-explosive charges fired on the Yucca Lake playa of the Nevada Test Site varied from 0.23 to 42.7 pounds per foot. Crater and ditch dimensions and volumes resulting from these shots, fired during the fall of 1959 and spring of 1960, are presented here as a function of charge burst depths. Scaling relationships determined are as expected; i.e., square-root scaling of linear-charge weight per foot for ditch width and depth and a direct linear-charge weight relationship to ditch volume are obtained. Permanent ground surface displacement varies as the -3.22 power of the scaled distance from the charge. Detonation effects, charge shape effects, ditch erosion, and ditch cross sections are discussed. The appendixes present Toboggan data, results of soil investigation, and mathematical treatment given the data.

This book was released on 1965 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six 1,000-pound high-explosive (HE) charges, each containing a capsule of radioactive tracer (Lanthanum 140), were detonated at depths varying from 15.0 to 21.4 feet in desert alluvium to permit selection of the optimum depth of burst commensurate with crater size and shape and radioactivity release. Using the burst depth thus selected, four row shots, consisting of five 1,000-pound HE charges in each row, were fired with intercharge spacing varying from 1.0 to 1.5 apparent crater radii to determine the optimum spacing to produce a channel of satisfactory size and proportion and relatively free of irregularities. The immediate purpose of the experiment was to aid in the design of a proposed nuclear row-charge event (Project Buggy).
