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.

Abstract: A single-point munition arming interface provides a more efficient approach to arming a canister-based munition. The single-point munition arming interface interfaces with electrically-initiated canister-based munitions. The arming interface locks and arms munitions in a baseplate system before initiation. The single-point munition arming interface includes a feature for removing the first safety in the munitions safe and arm device which is actuated upon insertion of the munition into the interface. The second step in the procedure is a user action which simultaneously locks the munition to the interface and completes the arming sequence by using a single mechanism to achieve both essential motions. The arming interface can be mechanically or electrically actuated allowing for remote activation which increases operator safety.
