摘要： An initiator that includes a substrate, an exploding foil initiator and a first switch. The exploding foil initiator coupled to the substrate and includes a bridge and a first bridge contact. The first switch has a first contact and a first insulator. The first contact is coupled to the substrate and spaced apart from the first bridge contact by a gap. The first insulator is disposed in the gap. The first switch is operable in an actuated mode in which electrical energy transmitted between the first contact and the first bridge contact is transmitted through the first insulator.

摘要： An initiator assembly having a base, first and second conductive elements, a first electrically insulating member and an energetic material. The first conductive element, which is configured to receive an electrical input, is coupled to the base and includes a tip. The first electrically insulating member is disposed over the tip. The second conductive element has a bridge that is disposed over the first electrically insulating member. The bridge is configured to vaporize in response to transmission of the electrical input from the tip of the first conductive element to the bridge. The energetic material is disposed over the bridge. Energy produced during vaporization of the bridge is transmitted to the energetic material to initiate at least one of a combustion event, a deflagration event and a detonation event in the energetic material. A method for operating an initiator assembly is also provided.

摘要： An initiator is provided for a munitions device that is intended to strike a target substantially along a trajectory direction and contains an explosive within a case. The initiator includes a sleeve, first and second anvils and an initiation pellet disposed between the anvils. The sleeve is disposed within the case and adjacent to the explosive, and defines an initiator interior aligned substantially parallel to the trajectory direction. The sleeve includes one or more orifices that extend therethrough between the explosive and the interior, the orifices being disposed adjacent to the pellet. The pellet is composed of a reactive material that chemically responds as a non-explosive to kinetic and thermal stimuli. The first anvil is disposed transverse to the interior and forward of the pellet, while the second anvil is disposed within the interior behind of the pellet, wherein the second anvil translates towards the first anvil substantially along the trajectory direction in response to the device striking the target. The pellet discharges particles through the orifices, the particles being directed into the explosive in response to the second anvil translating towards the first anvil. The sleeve can be disposed within the explosive. The reactive material can be a solid or powdered mixture of powdered aluminum and polytetrafluoroethylene or other fluoropolymer, or alternatively a thermite mixture of powdered metal and metal oxide and may include added polytetrafluoroethylene or other fluoropolymer.
