Abstract

Abstract

To investigate the safety of ammunition under underwater explosion, underwater sympathetic detonation characteristics of two types of explosives with aluminum shell are investigated via an underwater explosion test. The sympathetic detonation distance and safety distance of the test charges are determined, and the sympathetic reaction degree of the charge is analyzed based on the bubble energy. Results reveal that when the donor charge is a PBX charge with a 1.5 mm aluminum shell and the acceptor charge is an RS211 charge with a 1.0 mm aluminum shell, the sympathetic detonation distance is 60 mm and the safety distance of sympathetic detonation is 120 mm. When the donor and acceptor charges are PBX charges with 1.5 and 1.0 mm aluminum shells, respectively, the sympathetic detonation distance is 10 mm and the safety distance of sympathetic detonation is 30 mm. The reaction rates of completely detonated acceptor charges are only between 86% and 95% owing to a decrease in the bubble period caused by the fusion and collision of two bubbles.
