Fin stabilized subcaliber shell of large length to diameter ratio
First Claim
1. A fin-stabilized subcaliber armor piercing projectile having a large length to diameter ratio comprisinga metallic rear body,a metallic middle body, anda pointed front nose body, all of which are operatively joined to each other;
- the middle body is made of metal of high density selected from the group of depleted uranium and tungsten of at least a density of 18 gm/cm3, of lower ductility but higher brittleness than the metal of the rear body in a binder phase containing iron and nickelsaid rear body is made of metal of high density selected from the group of tungsten and depleted uranium in a binder phase containing iron and nickel, said rear body having a density of at least 18 g/cm3 ;
the volume of the middle body is substantially equal to the rear body;
the pointed front nose body consists of a metal of high ductility and density which has pyrophoric properties;
the rear body and middle body are joined to each other by butt surfaces and a metal sheathing surrounds said rear and middle bodies at these butt surfaces;
said sheathing extends only to about the middle of the middle body and has a front cutting edge;
said sheathing consists of steel;
said steel sheathing has means on its external periphery for connecting it to a sabot;
the rear body coaxially extends into said sheathing and fin-stabilization means are mounted on said steel sheathing; and
said middle body and rear body are joined by hard welding to each other.

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/cm3. 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.
In another embodiment, a drive cage with front and rear extension supports is provided, and the front and rear bodies are additionally connected to each other by a central pin.
