Abstract
Disclosed is a protective casing for ejectable munitions, having means enabling it to be broken through, this being a necessary operation for the sub-munitions to be ejected, in the next stage, without any difficulty of breaking through and ejection. The fracture lines are obtained by means of screens of high temperature resistant fibers arranged in a plane perpendicular to the internal and external surfaces of the casing. This casing is a part obtained, for example, by fusion and molding. The screen is integrated so that, during the casting of the metal, this metal links up all the fibers forming the screen together. The invention can be applied to protective casings, notably for rockets and munitions carriers.
