Title (EN) FIRING ARRANGEMENT
(FR) AGENCEMENT DE MISE À FEU
Abstract:
(EN) A firing arrangement for an initiator (1) includes a capacitor (16), an arming arrangement (6, 11, 14) for charging the capacitor (16) on receipt of an arming instruction and a trigger device (13). When a trigger condition is achieved which indicates sufficient charge on the capacitor (16), a trigger signal is automatically generated by the trigger device (13) to trigger discharge of the capacitor (16) through the initiator (1) to activate the initiator (1). The trigger condition may be a predetermined time after receipt of the arming instruction. The trigger condition may also be when the voltage across the capacitor reaches a threshold value.
(FR) La présente invention a trait à un agencement de mise à feu pour un initiateur (1), qui comprend un condensateur (16), un agencement d'armement (6, 11, 14) permettant de charger le condensateur (16) dès réception d'une instruction d'armement, et un dispositif de déclenchement (13). Lorsqu'une condition de déclenchement qui indique une charge suffisante sur le condensateur (16) est atteinte, un signal de déclenchement est automatiquement généré par le dispositif de déclenchement (13) afin de déclencher la décharge du condensateur (16) par le biais de l'initiateur (1) pour actionner cet initiateur (1). La condition de déclenchement peut être un laps de temps prédéfini après la réception de l'instruction d'armement.
