Determination of Minimum Nonpropagation Distance of 105 mm M1 Projectiles Grouped 16 on a Pallett
Abstract
A series of 119 tests were conducted with pallets containing 16 105 mm, M1 (composition B loaded) projectiles. Tests were performed with and without funnels used to fill the projectiles with explosives. This effort was in direct support of the modernization of the 105 mm LAP line at Lone Star Army Ammunition Plant but is also applicable to other similar loading lines. The test results indicate that pallets with 16 projectiles with funnels cannot safely be spaced at a distance as large as 40 feet without propagation of an explosive event. The safe nonpropagative spacing can be reduced to 20 feet when 3/4-inch thick steel plate blast shields are attached to the acceptor pallets. The tests also demonstrated that the initiation of a detonation of one projectile on a pallet results in a high order detonation of the remaining 15 projectiles. Pallets with 16 projectiles without funnels can safely be spaced at a 30-foot clear distance without propagation of an explosive event.
