Abstract

This research considers combinations of emerging technologies to provide an advanced warhead to be used in a C-RAM role. The warhead is used as a counter measure to attack and detonate incoming mortar rounds at safe distance from friendly troops. The warhead produces enhanced blast waves of such level that incapacitates the mortar during its flight. Highly energetic blast waves are generated from highly developed electromagnetic explosive devices called flux compression generators (FCG). These generators have been developed in form factors suitable for any contemplated C-RAM weapon that would be used to engage unfriendly munitions. FCGs produce tens of mega-amps of electrical current and very high corresponding magnetic fields that can be applied to several mechanisms to create enhanced blast-wave characteristics . One mechanism involves use of electrical current applied to the reaction zone of detonating high explosives to increase detonation velocity and pressure. A second mechanism creates near volumetric ignition of reactive materials for microsecond release of energy. The combined effects result in far greater energy, pressure, and impulse transmitted into the air about the device. The research addresses application of the mechanisms, optimization, and design of an integrated warhead for C-RAM application. Large-scale shock wave physics codes as well as FCG circuit solver codes will be used during the analysis and design exercises. Follow-on efforts will provide testing of concepts and proof of principle warhead demonstrations. Results will provide an advanced C-RAM warhead for Army use. Lockheed Martin Missiles and Fire Control is a team member and experimentalist on the effort.
