Abstract

The initiation of an output charge (152,) in response to an initiation signal can be delayed by conveying the initiation signal to a delay fuse (40) made from a reactive multilayer laminate to initiate an exothermic, self-sustaining alloying reaction in the laminate. The reaction follows a travel path which may be zigzag, coiled or otherwise elongated, to provide a desired delay time. The output charge (152) may be in an initiator mounted on a signal transmission line (111 ) that emits the initiation signal. A delay element (84) may contain a substrate (86) and a reactive multilayer laminate (88) disposed on the substrate and be shaped to define a serpentine travel path from the location of an input signal (I) to the location of an output signal (O). The delay element may be disposed in a plug comprised of solid members (62a, 62b, or in a tubular body (76).
