ABSTRACT:
A combustible ignition system for use in an illuminating flare warhead. The ignition system includes a pickup charge positioned contiguous the separation charge of the ignition initiator. The pickup charge is positioned such that the firing of the separation charge triggers combustion of the pickup charge. The pickup charge extends to a combustible train which comprises a continuous thin-layer explosive composition positioned within a plastic tubing. The firing of the pickup charge creates sufficient shock that the combustible train is detonated. The combustible train extends along the flare casing adjacent the parachute system and the illuminant. At the head end of the warhead, the explosive train connects to an output charge. The explosive shock of the explosive train is sufficient to detonate the output charge. The output charge transfers the combustion to a BKNO.sub.3 pellet basket within the illuminant igniter of the warhead. Ignition of the pellet basket ignites a propellant wafer which generates sufficient heat to ignite the illuminating composition of the flare.
