Title:
METHODS TO IMPROVE BURST UNIFORMITY AND EFFICIENCY IN EXPLODING FOIL INITIATORS
Document Type and Number:
WIPO Patent Application WO/2019/152073
Kind Code:
A3
Abstract:
Exploding foil initiator apparatus, system, and method that improve the current density in the bridge region by modifying the shape and dimensions of the bridge and related components. The exploding foil initiator reduces burn-back by making areas of the bridge thicker except directly under the flyer. The exploding foil initiator boards are built so the flyer is not connected to the rest of the top cover-lay. This avoids losing energy due to the flyer having to tear away from the solid cover-lay.
