Abstract
A cartridge for launching electromagnetic decoys with multiple charges comprises an elongated tube having an open upper end and a closed lower end, in which a plurality of flat holders, containing electromagnetic decoys are stacked over the length of the tube. At least one of the upper and lower surfaces of each flat holder is a conical surface in the shape of a flattened cone and each flat holder is provided in its lower part with a pyrotechnic charge able to project it upwards and to disperse the decoys. Each charge is connected to an adjacent charge by a pyrotechnic retarder and the upper most charge of the stack is provided with at least one pyrotechnic initiator, such that the arrangement formed by the initiator, the chargers and the retarders forms a continuous pyrotechnic chain, in order to allow, after detonation of the initiator, the successive ejection of the flat holders in a predetermined timed sequence.
