ABSTRACT:
A dispenser retains a hermetically sealed metal canister which holds a pyrophoric fluid, radar chaff, other electronic countermeasure materials or a combination thereof for ejection from an aircraft. Several openings in the canister are sealed with Pyrofuze foil material closures and a Pyrofuze wire braid is interconnected between each of the closures and the canister in close proximity to a Pyrofuze delay braid having one end thereof fixedly attached to the canister. A safety tab on one corner of the canister extends downward between the delay braid and the wire braid to prevent cross ignition until the canister is fully ejected from the dispenser. When a gas producing squib on the dispenser is fired, the Pyrofuze delay braid is ignited by the flame front from the squib and the canister is forced from the dispenser causing the safety tab to be automatically removed from the canister. This allows the delay braid to ignite the Pyrofuze wire braid which burns to each of the closures causing them to burn away thereby releasing and igniting the pyrophoric material from the canister.
