Sensitivity to Secondary Fragment Impact of Shell Filled with Molten Cyclotol 75/25, TNT, and Composition B

Abstract

The first phase of a two-phase experimental program was conducted to establish the impact sensitivity of 4.2-inch and 81-mm projectiles to secondary fragments. The target shells used in the experiment represented 'just filled' projectiles with HE fillers of Cyclotol 75/25, TNT, and Composition B in the molten condition. The threshold impact velocities of the concrete fragments which initiated the shells were determined. In addition, an empirical model was developed which significantly reduces the number of tests required to determine the impact sensitivity of any given ammunition item. In the second phase, simulated torpedo warheads filled with PBXN-103, H-6, HBX-1, and HBX-3 at ambient temperature were impacted with brick wall fragments representing potential storage hazards. Both the impact characteristics which caused threshold initiation and those which resulted in acceptor insensitivity were determined.
