Abstract:

This report describes a study of the air blast produced by sequentially detonated high explosive charges. Criteria are established relating the coalescence of successive blast waves to explosion time delay, charge weight, and distance from the explosion site. A finite-difference technique based on the method of characteristics was used to determine numerically the pressure fields produced by spherical charges with various time delays between successive detonations. Small-scale experiments were conducted with hemispherical explosive charges totaling 2 lb in weight detonated on a rigid surface. Transient pressures were observed at six stations on each of two gage lines. Comparisons are made between the peak pressures and pulse separations predicted numerically and those obtained experimentally. The results are useful in developing recommendations for siting of structures adjacent to multiple-unit explosive stores.
