A high-precision pyrotechnic initiator (100) is well adapted for rapid, precise ignition of solid and liquid energetics. A rigid housing (18), for example formed of stainless steel or an SiC-treated semiconductor substrate material, contains a pyrotechnic. When ignited, the reaction, or explosion, of the pyrotechnic is confined to the housing (18). The release of energy creates a hot particulate in which the formation of solid byproducts is mitigated or eliminated. The flame is directed through an outlet (66). In one embodiment, a microcapillary tube (46) may be placed in communication with the outlet (66), the tube (46) including a primary front vent (50) and secondary side vents (48), which serve to increase system efficiency and reliability. A dual bridge wire (52) may be provided for improving system reliability. The resulting assembly thereby performs the combined functions of both an igniter and a flash tube and a complete ignition train is provided in a manner that overcomes the limitations of the conventional configurations. |
