초록 ▼

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.

대표청구항 ▼

1. An initiator assembly comprising: a base;a first contact coupled to the base, the first contact defining a first bridge element;a first electrically insulating member disposed over the first bridge element such that the first bridge element is disposed along an axis between the base and the first electrically insulating member;a second bridge element coupled to the first electrically insulating member such that the first electrically insulating member is disposed along the axis between the first bridge element and the second bridge element;a flyer layer coupled to the second bridge element; anda barrel coupled to the base and disposed over the second bridge element and at least a portion of the flyer layer, the barrel being disposed along the axis. 2. The initiator assembly of claim 1, wherein the second bridge element has a semi-circular end that overlaps an end of the first bridge element. 3. The initiator assembly of claim 2, wherein the first bridge element has a semi-circular tip and is disposed under the second bridge element. 4. The initiator assembly of claim 3, wherein an edge of the semi-circular end of the second bridge element and an edge of the semi-circular tip of the first bridge element cooperate to form a circle. 5. The initiator assembly of claim 1, wherein a trigger element and a second electrically insulating member are received between the first electrically insulating member and the second bridge element, the trigger element being disposed along the axis between the first and second electrically insulating members and being disposed along the axis. 6. The initiator assembly of claim 5, wherein the second bridge element has a first area and wherein a portion of the trigger element that is in-line with the second bridge element along the axis has a second area and wherein the second area is less than ten percent of the first area. 7. A method comprising: providing an initiator assembly having a first bridge element, a second bridge element, a first electrically insulating member, a flyer layer and a barrel, the first bridge element and the second bridge element being spaced vertically apart along an axis, the first electrically insulating member being disposed between the first and second bridge elements along the axis, the flyer layer overlying the second bridge element, the barrel defining a barrel aperture, the barrel aperture extending longitudinally along the axis and being disposed over at least a portion of the flyer layer; andtransmitting electrical power through the first bridge element, the first insulating member and the second bridge element to vaporize the first and second bridge elements, wherein vaporization of the first and second bridge elements causes a portion of the flyer layer within the barrel aperture to be expelled from the barrel. 8. The method of claim 7, wherein the initiator assembly further comprises a second electrically insulating member and a trigger element, the second electrically insulating member being disposed along the axis between the first electrically insulating member and the second bridge element, the trigger element being disposed between the first and second electrically insulating members, and wherein the method further comprises applying electrical energy to the trigger element. 9. The method of claim 8, wherein the first and second electrically insulating members are damaged when electrical energy is applied to the trigger element. 10. The method of claim 8, wherein the electrical insulation between the first and second bridge elements that is provided by the first and second electrically insulating members is reduced or eliminated after the application of electrical energy to the trigger element.
