Pulsed Power Generators with Dynamic Connectors

EPPI proposes to develop a test plan and design an experimental hardware testbed for discharging a cascaded Flux Compression Generator (FAG) pulser system in conjunction with explosively formed dynamic electrical connectors into an electrical load that meets the Munition Directorate's (AFRL/MN) requirements. Initial designs for compact seed and megajoule output FCGs are now being developed through a Phase II (contract F08630-97-C-0013) and will form the basis for this effort. The FCG designs previously developed will be modified to closely match into the electrical load defined by the dynamic connector's electrical parameters and the load as defined by AFRL/MN. The close matching of the FCG design can significantly increase the FCG performance. The connector design will be developed jointly by EPPI and a subcontractor to determine the space and time characteristics of the connector along with an estimate of the electrical parameters of the connector at various lengths. This effort builds on the FCG designs of the previously awarded Phase II and incorporates an entirely new aspect relating to the connectors and special requirements for coupling current onto the explosive dynamic electrical connector. EPPI will subcontract to Alliant Techsystms, a company with expertise in connector technology.
