Projectile for a defensive projecting device

摘要

A projectile to be fired by a electric ignition defensive projector attached to an object to be defended has a propellant charge and an active charge and ignition devices for igniting the propellant and active charges. The active charge-ignition device is a mechanical ignition device including a firing pin and a firing pin spring. The mechanical ignition device is tensioned and released by a grappling line which is connected to the projector or a part of a projectile which remains in the projector, and is likewise connected to the firing pin. After the projectile has been fired and when it has travelled through a range of fire that corresponds to the length of the grappling line, then the firing pin spring is tensioned by the now taut grappling line and the firing pin is subsequently released which then ignite the active charge of the projector via a percussion cap and a pyrotechnical igniter train.
