Safe Separation Distance of 81mm Mortars by Analogy to the M374 Series Testing
Abstract
Safety regulations require a safe separation distance between ammunition items to prevent propagation between buildings or between bays when conveyors are used to transport such items. Establishing such a distance usually requires testing to obtain the 50 samples necessary for statistically acceptable data. This paper presents the rationale used to avoid testing the new generation M821E1/M889E1 81mm mortars by comparing the velocities, and fragment weights from arena tests, configurations, and projectile physical parameters with the older M374 Series 81mm mortar. The M374 mortar was extensively tested in several configurations and use of the new 81mm mortar safe separation distance data established by this analogy allows production of the new mortar on existing production lines without conducting testing and expending costly items.
