A projectile with rear and front sections able to deliver payloads of submunitions contained inside the projectile after separation of the rear from the front section. The rear section is fitted with an assembly of thin blades. When both sections are assembled, the blades are partially in the rear section and partially in the front section, and when the two sections are separated, the blades spread out. The assembly is such that the length of blade that spreads out is greater than the length of blade that was in the front section before separation of the two section.

The disclosed device comprises, in the first element, on which the second element is mounted, a peripheral housing opened outwards, a circlip engaged in said housing, comprising teeth capable of getting engaged in retaining means of the second element, and a means to bring the ends of the circlip closer together in order to retract it and to bring out the teeth of the retaining means controlled by a delay means. The disclosed device is particularly suited to the locking and unlocking of sub-munitions parachute containers.

For suspending a sub-munition from a plate carried beneath a parachute, an arm is hinged with the plate and the body of the munition, and a structure has two positions for which the sub-munition is respectively vertical or inclined. The structure also includes a system of guiding the tilting between the two positions. The center of gravity of the sub-munition moves downwards on a vertical line during tilting of the sub-munition to an inclined position. The device forming the subject of the invention enables the swinging caused by tilting the sub-munition into an inclined position to be avoided, and it is simple and economical to manufacture.

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.
