Determination of Nonpropagation Distances for 105-mm HEAT-T Cartridges M456
Abstract
A series of tests were conducted to establish the nonpropagation distances between various subcomponents and assemblies of the 105-mm HEAT-T cartridges M456. Five simulated loading line configurations were initially considered for testing: M83 primers, M148 cartridge cases, M456 projectiles, and M456 cartridges vertically and horizontally oriented. This effort was in direct support of the modernization of the Milan Army Ammunition Plant, Milan, Tennessee, but it is applicable to other similar facilities. The test results were as follows: (1) M83 primers will not rupture their containing M148 cartridge case, therefore nonpropagation tests were unnecessary; (2) Use of the complete cartridge nonpropagation distance for both the loaded M148 cartridge case and the M456 projectile conveyor spacing is a valid 'worst' case substitution; and (3) The safe nonpropagation distance for fully loaded M456 cartridges is 58.4 centimeters (23.0 inches) in a vertical orientation and 38.1 centimeters (15.0 inches) in a horizontal orientation, provided 7.6 centimeter (3.0 inch) diameter aluminum bars (6061-T6) are used as shields between cartridges in both cases. (These are not minimum distances, but are tailored to fit a given loading line situation).
