Available in PDF, EPUB and Kindle. Book excerpt: Airblast was measured perpendicular to and off the ends of row-charge explosions and compared with airblast from single charges. It was found that Prow was approx. n(B) Psingle, where P is peak overpressure and n the number of charges. B was different for each blast parameter examined: ground-shock-induced peak overpressure, peak overpressure from venting gas, peak negative pressure, and positive and negative impulse. Values of P increased as spacing decreased. Airblast was always greater perpendicular to the row than off the end, by an amount which increased as the number of charges increased.
