Abstract
Disclosed is a system for the holding of multiple warheads, placed in a missile rotating on its longitudinal axis and dropped in trajectory through an end of the missile. Each stage of the warhead includes at least two distinct parts which have to be separated laterally at the moment of dropping, the missile including a casing inside which the warhead is placed. For each stage, mechanisms to fix the parts at the said stage are arranged so that each stage forms a compact unit so as not to cause major radial stresses against the casing due to the centrifugal force created by the rotating missile. The fixing mechanisms are retractable at the moment when the parts are dropped, by means of inertia blocks that are subjected to the centrifugal force. The invention can be applied to sub-munitions and mortar shells.
