Abstract
An improved inertial projectile arrangement including a subcaliber projectile penetrator which is composed of a prepenetrator portion with a nose point and a main penetrator portion. The penetrator has a large length/diameter ratio and a high density. A sabot, composed of at least two segments, encompasses a part of the prepenetrator portion. The periphery of the encompassed prepenetrator and the sabot being joined to each other by form-locking means. The sabot segments separate from the penetrator upon exiting from the muzzle of the gun barrel from which the projectile is fired. The form-locking means are at least partially formed of irregularities or unevenesses on the periphery of the encompassed prepenetrator portion and the interior periphery of the sabot. A plurality of fracture zones and a transfer frusto-conical portion are disposed on the prepenetrator. The fracture zones achieve an intended breakup of the prepenetrator upon impact. A predetermined number of the fracture zones form part of the form-locking means. The frusto-conical transfer portion adjoins the fracture zone most distant from the nose point of the prepenetrator at one of its ends and the main penetrator por…
