Cavity explosion calculations for the Cowboy program.
A presentation of calculations corresponding to the cavity explosions of the Cowboy program. These were spheres of high explosive ranging from 20 to 2000 lbs detonated in spherical cavities of 12 and 30 ft diameters. Wall pressures as a function of time are given, together with the explosive properties influencing the wall pressures. Some comparisons with measured pressures are also included. The explosion history of one typical problem (20 lbs in 12-ft cavity) is examined in an appendix.
