Effect of Initiation Configuration on Blast Performance of Cylindrical Explosive Charge—An Experimental Investigation

Abstract

Experiments were conducted on cylindrical explosive charge with three different initiation configurations viz., geometric center initiation, single line side initiation and two line side initiation. Blast pressure parameters were measured at different distances from explosive charge. Peak over pressure from single line initiated explosive charges along azimuth direction at 180o is about 40% more than that of point initiated charges at a distance of 1m from point of burst. Over pressure and impulse values of line initiated charges drop down to those values obtained from point initiated charges beyond a distance of 10 times charge diameter from point of burst. Total impulse is observed to be less in case of two-line initiated charge as compared to point initiated and single line initiated charge.
