Minimum Nonpropagation Distances for Various LAP Facility Configurations of the 30-mm XM789 HEDP Projectiles
Abstract
As part of an Army wide expansion and modernization program, the safe separation distances for various production facility configurations of 30-mm XM789 HEDP projectiles were studied, tested, and statistically determined in a series of tests. The test results were used to establish safety criteria for new manufacturing Load-Assemble-Pack (LAP) facilities and also existing facilities undergoing renovation. The program to determine the necessary minimum nonpropagation distance was drafted by ARRADCOM and was subsequently conducted in a series of six test phases. Within each test phase, exploratory and confirmatory tests were conducted resulting in the following safe separation distances, statistically confirmed at the 95% confidence level: (1) bare PBXM-5 pellets, stacked two each, 25.4 millimeters (1.0 inch) resulted in a 6.84% probability of propagation, (2) shell body with loose pellets inserted, 25.4 millimeters (1.0 inch) resulted in a 6.60% propagation probability, (3) loaded body assembly, 25.4 millimeters (1.0 inch) resulted in a 7.10% propagation probability, (4) loaded body assembly (heated), 76.2 millimeters (3.0 inches) resulted in a 7.10% propagation probability, (5) fuzed projectile, 76.2 millimeters (3.0 inches) resulted in a 5.97% propagation probability, and (6) fuzed projectile (heated) propagations were recorded up to and including distances of 381.0 millimeters (15.0 inches).
