Exploding bridgewire initiators
Did you know?
WebA pyrotechnic fastener (also called an explosive bolt, or pyro, within context) is a fastener, usually a nut or bolt, that incorporates a pyrotechnic charge that can be initiated remotely. One or more explosive charges embedded within the bolt are typically activated by an electric current, and the charge breaks the bolt into two or more pieces. WebFor this reason, initiators called "exploding bridgewire" detonators were developed, and widely used in nuclear weapons. Exploding bridgewires are like blasting caps in that they are electrically detonated. The difference is that much more current is sent through them much more quickly. The wire itself literally explodes.
