Focused Miniature Ordnance Technologies

In order to develop miniaturized weapon systems capable of defeating fleeing targets in urban environments safely, a new class of miniaturized initiator,  ULEEFI (Ultra Low Energy Exploding Foil Initiator) is needed. The new initiator will need to be smaller, lighter and incorporate multi-functionality in the design. Legacy systems currently incorporate large, out-of-line safe and arm systems with many components (ie. initiators, PICS, leads and boosters). The interface between the safe and arm system and the warhead needs to be redefined based on todays technology. The next generation of firing system miniaturization will happen as sub-component technologies in the initiator are integrated or eliminated and EFI firing energy reduction is achieved. LEEFI initiators and their firing systems are shrinking in size and weight and offer superior safety and performance over traditional out-of-line systems. The LEEFI is capable of delivering timing accuracies, which allow multi-function output capabilities in the warhead design. Reynolds Systems LEEFI initiators employ the use of RSI-007 explosive, a CL-20 based explosive that was developed under a SBIR with the Navy. The RSI-007 has unique energy characteristics including short run up to full detonation and extreme energy density, making the explosive an excellent choice for compact weapon systems. BENEFIT: Although many versions of the LEEFI devices are now in production and many more are in development at RSI, the emphasis for this Phase 1 study shall be placed on designing a whole new class of initiator, which is smaller in size and weight and lower in energy requirements. This initiator would have its own high voltage switching technology. This initiator would also have sufficient output to either act as the warhead or directly initiate the main fill warhead without the need of intermediate energetics. It is anticipated that RSI will be able to demonstrate the initiator in Phase 1 by showing a decrease in firing energy of 20% from a current LEEFI (with a goal of 35%) and include a working on-chip switch capable of triggering the initiator.
