Air-to-Water Blast Wave Transfer

Abstract

A study to characterize the shock wave induced in the water directly below an explosion in air has been carried out. Spherical and cylindrical charges weighing up to 3.63 kilograms were fired. Burst heights extended from 1. 58 meters/kilogram 1/3 down to the water/air interface. All cylinders were fired with their major axis perpendicular to the water surface. Both the airblast and underwater shock waves were measured. Both the spherical and cylindrical charges produced underwater pressure-time histories that were characterized by multiple pressure pulses. Those from cylinders were more reproducible.
