Abstract
An initiator (100) assembled from a housing (112), an output charge (144) and an initiation means (110, 120, 58, 54) includes a pulverulent ignition charge (46a) disposed in direct initiation relation to the initiation means, and an output charge (144) that may contain a pulverulent deflagration-to-detonation transition (DDT) charge (144a) and an explosive base charge (144b). The ignition charge (46a) has an average particle size of less than 10 microns, or even less than 5 microns, e.g., 1 to 2 microns. The initiation means may include a semiconductor bridge (18) and the ignition charge (46a) may be compacted with a force of less than about 5880 psi, e.g., with a force of 1000 psi. In another embodiment, an initiator (210) includes a low-energy electrical initiator (234), a loosely packed BNCP ignition charge (218) and a pyrotechnical output charge (214).
