Method and device to reduce the risk of the spread of an unintentional local initiation in an ammunition store containing shaped charges

摘要

The present invention relates to a method and a device to prevent the unintentional initiation of a shaped charge (2) caused by fire or other means resulting in the initiation spreading to other adjacent charges and causing a sympathetic detonation. The invention is characterised by an expendable body (4, 10-13) made of a material which is resistant to shaped charges and which is of sufficient length to prevent the shaped charge jet penetrating through the expendable body in the direction of effect (3) of the jet (2). <IMAGE>
