A chaff cartridge is made up of a plurality of chaff interpackets contained in subprojectiles. The subprojectiles are each provided with fins and the fins of each subprojectile in a chaff cartridge provide a different drag to cause the spacing out of the subprojectiles. The fins, additionally, cause the subprojectiles to rotate and thereby radially disperse the chaff.

Dispersive subprojectiles for chaff cartridges

Bundles of chaff fibers are fed into a rotating preacceleration chamber having a diverging outlet. The chaff fibers are rotated with the preacceleration chamber and are forced radially outward by centrifugal force. A feed mechanism forces the rotating chaff fibers toward the diverging outlet from which they are propelled outwardly at a high velocity and at an angle almost orthogonal to the rotational axis of the chaff dispenser.
