ABSTRACT:
The sub-munition is provided with an arming device comprising a striker member, movable substantially in the direction of its longitudinal axis, and a detonator carried by a slide movable from a first position in which the detonator is located out of the path of the striker member to a second position in which the detonator is brought into the path of the said member and beneath it; the striker member is provided with a threaded stem screwed into a threaded hole of a bush movable axially on the body of the sub-munition in such a way that the striker member is brought from the said first to the said second position upon unscrewing of the stem from the threaded hole; a pair of strip form flexible elements are connected to the striker member, one end of which flexible elements is fixed to the striker member and each of which can be disposed, when the sub-munition is expelled from the projectile, in a twisted configuration in such a way that the aerodynamic forces acting on them cause a moment to be transmitted to the striker member to unscrew this member itself from the associated threaded hole.
