Patent ID: 10871354

Abstract:
An initiator assembly that includes a housing assembly, an exploding foil initiator, an input charge and an output charge. The housing assembly defines a first cavity, a second cavity, and a bulkhead member between the first and second cavities. The exploding foil initiator is received in the housing assembly and includes a bridge, a flyer and a barrel. The flyer overlies the bridge and is disposed between the barrel and the bridge. The barrel defines a barrel aperture. The input charge, which is formed of a secondary explosive, is received in the housing assembly and is disposed in-line with the barrel aperture. The output charge assembly is received in the housing assembly and is formed of a secondary explosive. Energy released from detonation of the input charge in response to operation of the exploding foil initiator penetrates the bulkhead and initiates detonation of the output charge.
