Selectable Initiation Shaped Charges
Several initiation-based selectable detonation techniques have been developed to allow shaped charge warheads to achieve not only deep penetration, but also to exhibit enhanced lethality effects against light armored targets, geologic materials and in a variety of demolition applications. For light armor or softer targets, the lethal area can be increased by spreading penetration material over a wider area. Recently, multi-detonator initiation jet shaping procedures were applied to full-size shaped charge warheads. These warheads successfully demonstrated a significant increase in lethal area against light armor targets. This type of selective initiation was applied to conical, hemispherical and trumpet lined shaped charge warheads. Employment of these selective initiation techniques against masonry targets demonstrates the potential advantages of this technology for use in demolition and urban combat applications. Furthermore, this technology can be exploited to enhance warfighting capabilities to provide increased lethality, agility and survivability to U. S. Soldiers.
In an effort to expand the role of conventional warheads, the TACOM-ARDEC Energetics and Warheads Division has developed and demonstrated several initiation-based selectable detonation techniquesto allow shaped charge warheads to achieve both deep penetration and enhanced effects against light armor, geologic materials encountered in urban warfare or demolition applications. Modeling and experimentation have shown that jet output is predictable and can be varied significantly for use against a number of different target applications. For light armor or softer targets, the lethal area can be increased by spreading penetration material over a wider area. Multi-detonator initiation based jet shaping procedures were applied to conical, hemispherical and full-size trumpet shaped charge warheads to evaluate performance against standard targets. These warheads were used to successfully demonstrate a significant increase in lethal area against light armor targets. Test firings against masonry targets demonstrated the potential advantages for demolition and urban combat targets.
