Abstract
A high-precision pyrotechnic initiator is well adapted for rapid, precise ignition of solid and liquid energetics. A rigid housing, for example formed of stainless steel, contains a pyrotechnic. When ignited, the reaction, or explosion, of the pyrotechnic is confined to the housing. 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. In one embodiment, a microcapillary tube may be placed in communication with the outlet, the tube including a primary front vent and secondary side vents, which serve to increase system efficiency and reliability. A dual bridge wire 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.
