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

An igniter assembly comprising:

• a housing;
• a first barrier received in the housing and cooperating with the housing to form a chamber;
• an input charge disposed in the chamber and formed of a secondary explosive;
• a second barrier disposed on a side of the first barrier opposite the input charge;
• and
• an output charge formed of a pyrotechnic material and disposed on a side of the second barrier opposite the first barrier, the output charge being combustible in response to a chemical reaction that involves at least a portion of the second barrier and energy that is generated through detonation of the input charge, wherein combustion of the output charge produces a pyrotechnic output and wherein the first barrier and the housing cooperate to form a structure that prevents the output charge from being cooked-off or initiated in response to heat, pressure or both heat and pressure generated by the input charge if the input charge is electrically cooked-off.

An igniter assembly comprising:

• a housing;
• a first barrier received in the housing and cooperating with the housing to form a chamber;
• an input charge received in the chamber and formed of a secondary explosive and having a mass that is less than or equal to about 20 milligrams;
• an initiator disposed in the housing adjacent the input charge, the initiator being selectively operable for initiating detonation of the input charge;
• a second barrier disposed on a side of the first barrier opposite the input charge;
• and
• an output charge formed of a pyrotechnic material and disposed on a side of the second barrier opposite the first barrier, the output charge cooperating with the second barrier to cooperatively produce a pyrotechnic output in response to detonation of the input charge;
• wherein the first barrier cooperates with the housing to form a structure that inhibits the output charge from being cooked-off or initiated in response to heat, pressure or both heat and pressure generated by the input charge if the input charge is electrically cooked-off.

An igniter assembly comprising:

• a housing with an aperture formed in a first end of the housing;
• a first barrier received in the aperture in the housing and cooperating with the housing to form a chamber, the first barrier being generally cup-shaped;
• an input charge received in the chamber and formed of a secondary explosive and having a mass that is less than or equal to about 20 milligrams;
• an initiator disposed in the housing adjacent the input charge, the initiator including an exploding foil initiator and being selectively operable for initiating detonation of the input charge;
• a plurality of electric contacts extending through the housing and electrically coupled to the initiator;
• a plurality of seal members formed of glass, each of the seal members sealingly engaging the housing and a respective one of the electric contacts but not extending into the chamber;
• a second barrier disposed on a side of the first barrier opposite the input charge;
• and
• an output charge formed of a pyrotechnic material and disposed on a side of the second barrier opposite the first barrier, the output charge cooperating with the second barrier to cooperatively produce a pyrotechnic output in response to detonation of the input charge;
• wherein the first barrier cooperates with the housing to form a structure that inhibits the output charge from being cooked-off or initiated in response to heat, pressure or both heat and pressure generated by the input charge if the input charge is electrically cooked-off.
