Sensitivity Study of Molten Cyclotol 75/25, TNT, and Composition B filled Shells Subjected to Secondary Fragment Impact
Abstract
A two phase experimental program has been completed which provides secondary fragment impact sensitivity data useful to designers of munition facilities. In the first phase the targets tests were 4.2 inch and 81 mm shells. All target shells depicted the 'just filled' condition of the loading operation where the Cyclotol 75/25, TNT, and Composition B is in the molten state. Threshold impact velocities for initiation by concrete fragments were determined. An emperical model was developed which significantly reduces the number of tests, and which enables us to determine the impact sensitivity of an ammunition item. In phase two the targets tested were simulated munition (torpedo warheads). All munition targets were at ambient temperature and were filled with PBXN-103, H-6, HBX-1, and HBX-3 explosives. The impact velocities at which brick wall fragments did not detonate the simulated munition were determined.
