  • Patent number: 4638738
    Abstract: In a spin stabilized flight shell, a front body and a rear body are attached to each other at a first joint, and a pointed body is attached to the front body at a second joint. The materials of the front and rear bodies contain a high proportion of at least one metallic element having a density of at least 18 g/cm.sup.3. The rear body has higher ductility than the front body, which in turn is more brittle, so that it fragments easily.In one embodiment, a case can be used to protect the first joint and the front body prior to impact. The case is developed in a circumferential region as a form locking zone, for interaction with a drive cage. The front and rear bodies and the case 38 are connected at a contact zone, for example by brazing, and is of circular cylindrical shape with a diameter equal to that of the front and rear bodies. At the rear, the case is developed into a support for the stabilizing fin assembly, and is provided with a internal compartment for a tracer composition.
