Abstract
A priming system for the explosive charge of a sub-munition carried on board a carrier comprises a main firing pin, a primer tube operative to move from a safety position to an armed position, at least two devices to lock the primer tube in the safety position before the sub-munition is ejected, and a self-destruct mechanism operative to destroy the sub-munition after a predetermined delay. A first one of the locking devices is formed of a cam operative to move from a cam safety position, in which it forms a limit stop preventing the primer tube from passing freely into an armed position, to a retracted position in which it allows free passage of the primer tube. The cam carries an auxiliary firing pin to ignite a delay cord of the self-destruct mechanism. A second one of the locking devices engage the primer tube by the percussion tip of the firing pin to hold the primer tube in a safety position.
