PERFORMANCE OF FOX-7 (1,1-DIAMINO-2,2-DINITROETHYLENE) IN SHAPED CHARGE APPLICATIONS

摘要

The use of insensitive munition (IM) becomes more and more important to increase the safety of weapon platforms, transportation, storage and munition handling. One way to obtain IM-properties is to use a low sensitive secondary high-explosive (HE) in the warhead. The FOI-developed low sensitive HE FOX-7 (1,1-diamino-2,2-dinitroethylene, also denoted DADE or DADNE) is an interesting candidate for replacing commonly used more sensitive explosives such as Comp B. In this paper the performance of FOX-7 compared to hexotol (Comp B) in shaped charge applications are presented. The initiation ability by a standard booster charge and the propagation of the resulting detonation front in a cylindrical charge were studied. The jet characteristics were compared using a high precision shaped charge. The jet straightness and velocity as well as the fragmentation time were evaluated. Finally, the jet penetration capabilities were measured. In almost all aspects the FOX-7 charge improved upon the hexotol baseline charge.
