Energetic material initiation device utilizing exploding foil initiated ignition system with secondary explosive material

A energetic material initiation device, comprising:

• a base;
• an initiation charge;
• an exploding foil initiator coupled to the base and operable for selectively producing a shockwave to initiate detonation of the initiation charge;
• a hollow sleeve housing the initiation charge;
• an ignition charge;
• a barrier structure disposed between the initiation charge and the ignition charge;
• and
• a cover coupled to the base, the cover cooperating with base to house the exploding foil initiator, the initiation charge, the hollow sleeve, the ignition charge and the barrier structure;
• wherein combustion in the ignition charge is initiated by a chemical reaction in which energy released during detonation of the initiation charge and an ensuing reaction with at least a portion of the barrier structure;
• and
• wherein the cover ruptures in response to the initiation of combustion in the ignition charge to thereby provide a pyrotechnic output.

An energetic material initiation device, comprising:

• a base including a ceramic, leadless chip carrier;
• an initiation charge;
• an exploding foil initiator coupled to the base and operable for selectively producing a shockwave to initiate detonation of the initiation charge;
• a hollow sleeve housing the initiation charge;
• an ignition charge;
• a barrier structure disposed between the initiation charge and the ignition charge, the barrier structure including a reactable member and an oxidizer barrier;
• and
• a cover coupled to the base, the cover cooperating with base to house the exploding foil initiator, the initiation charge, the hollow sleeve, the ignition charge and the barrier structure, the cover being formed with at least one stress riser, the at least one stress riser including a plurality of intersecting features, the features being selected from a group consisting of grooves and perforations;
• wherein the initiation charge, the barrier structure and the initiation charge cooperate to convert the shockwave into a pyrotechnic output that ruptures the cover in an area determined by the at least one stress riser.
