The Containment of Blast Effects from the Detonation of Small High Explosive Charges.
Abstract
A spherical containment device to be used for the safe transportation of high explosives was evaluated for its ability to suppress blast effects from internal explosive detonations of charge weights extending to 483 gms (17.03 oz. ) of 50/50 pentolite explosive. The device consisted of a steel sphere with a specially designed port to permit the placement of high explosive material inside. In a series of tests, charges of different weights were detonated inside the device. Overpressure measurements were recorded at 61 cm. from the outside surface and pressure measurements were made on the interior. The strain experienced by the sphere was measured on the outside surface. The study demonstrated that the design criteria has been met since the device was capable of containing the explosive gases and restricting the exterior overpressure below the threshold for human ear drum rupture.
