A case jacket made of a felted, in particular combustible fibrous material, comprising a cylindrical case jacket portion and a calotte-shaped case bottom which is connected to an end of the cylindrical case jacket portion, wherein the bottom-side end of the case jacket portion has a first inside diameter and a first outside diameter, and wherein the case bottom has an annular connecting edge towards the case jacket portion, which has a second inside diameter that is smaller than the first inside diameter, and a second outside diameter which is smaller than the second outside diameter, includes a conical connecting portion whose one end has the first inside diameter and the first outside diameter and is connected to the bottom-side end of the case jacket portion, and whose other end has the second inside diameter and the second outside diameter and is connected to the connecting edge of the case bottom, wherein the angle of inclination of the inner wall and the angle of inclination of the outer wall of the conical connecting portion with respect to the cylinder axis are not more than 10°.

Case jacket

A shell with a subcaliber penetrator, which has a conical tailpiece, and with a basically disk-shaped propulsion element, wherein the conical tailpiece has a frustum-shaped recess that is open towards the rear end. The propulsion element is joined with the penetrator, preferably by a screw connection (projectile fastening bolt). To this end, a bolt element joins the propulsion element and the penetrator in the area of the tailpiece and has a borehole that is open at the rear end, into which propellant charge gases flow when the shell is fired and cause rending of the bolt element and thus separation of the propulsion element from the penetrator.

The invention relates to a method for producing a penetrator () from a tungsten heavy metal with a high fraction of tungsten and an outer sheath (), which consists of a material that is more ductile in relation to the penetrator core (). To produce a penetrator () of this type in a cost-effective manner, according to the invention a twin-hopper filling device, which corresponds to the dimensions of the penetrator core (), is introduced concentrically into a compression mold () that corresponds to the outer dimensions of the penetrator (). The inner pipe () is filled with a first tungsten powder blend with a high fraction of tungsten for producing the penetrator core (), while the annular gap between the outer wall of the inner pipe and the inner wall of the compression mold () is filled with a second tungsten powder blend with a lower fraction of tungsten, (approximately between 85% and 91%), than the first powder blend. Once the inner pipe () has been removed from the compression mold (), the powder blend is then compressed in the known manner to produce the penetrator (), the compressed body is subsequently sintered and cold-formed and the penetrator slug is finally finished.

The invention relates to a projectile () having a sub-caliber projectile core () and a guide cage or sabot () that comprises a driving element (), which acts on the projectile core () at the rear thereof and is in the form of a plate composed of metal. In order to produce such a projectile () at low cost, the projectile core () and the driving element (), which is in the form of a plate, are inserted as inserts into an injection-molding tool, and are extrusion-coated so that the injection-mold shape is chosen so that the contour of the guide cage or sabot () of the projectile () is produced after the injection-molding process.

The invention relates to a cartridge having a propellant charge casing at least partially filled with a propellant charge powder, and a projectile part connected on a front of the propellant charge casing, wherein the propellant charge casing comprises a casing cover, a casing sheath and a casing base, and the casing sheath is connected to the projectile part via the casing cover and to the casing base via a spring steel sheet. In order to achieve different amounts of propellant charge powder filled into the same propellant charge casing without igniting the propellant charge at undesirable blast waves, a sack-shaped container that is completely filled with the respective amount of propellant charge powder is disposed inside the propellant charge casing so that the container, and thus also the propellant charge powder, extends in the direction of the central longitudinal axis of the cartridge.

Cartridge

A sabot projectile with a subcaliber projectile body and a sabot, which includes a propulsion element that acts on the rear end of the projectile body and a segmented, essentially cylindrical metal guide cage, which is located at the front end of the propulsion element. The guide cage has a central opening that extends in the axial direction, through which the projectile body is passed. So that the sabot projectile is relatively inexpensive to manufacture, has a low weight, and ensures good detachment of the sabot from the projectile body after discharge, the guide cage is a hollow cylinder, on whose inside wall preferably several radial transverse ribs are arranged, which are spaced some distance apart and extend both in the direction of the longitudinal axis of the sabot and in the direction of the projectile body.

Sabot projectile

A sabot projectile with a subcaliber penetrator and a sabot, which has a propulsion element that acts on the rear end of the penetrator, a segmented, essentially cylindrical guide cage, which is connected to the front end of the propulsion element, and a segmented, disk-shaped metal guide element that extends radially inward in the front area of the guide cage and holds the penetrator. The disk-shaped guide element has a slightly convex contour in the direction of flight of the projectile and the material and the wall thickness of the guide element are chosen in such a way that convex area of the guide element is pushed back slightly when the sabot projectile is fired, so that the outer marginal area of the guide element rests against the inside wall of the gun barrel from which the sabot projectile is fired, and/or the inner marginal area of the guide element, which faces the penetrator, rests against the outer surface of the penetrator.

A full-caliber projectile having a cylindrical guide region ( ) and an ogival projectile tip ( ). To improve the stabilization of the projectile ( ) inside a gun barrel ( ) in a simple manner, and therefore improve the intermediate ballistics and hit accuracy over those of comparable projectiles, a guide ring ( ), which is segmented in the circumferential direction, and whose outer diameter is smaller than the inner diameter of a gun barrel ( ) of the same caliber, is secured to the projectile tip ( ) such that the radially spaced guide-ring segments ( ) detach from the projectile ( ) in the gun barrel ( ) when a predetermined firing acceleration occurs in the gun barrel, and the segments ( ) are pushed toward the projectile ( ), axially relative to the cylindrical guide region ( ), by dynamic pressure until they rest against the inside wall ( ) of the gun barrel ( ) and against the projectile ( ).

Full-caliber projectile

A cartridge, comprising a cartridge case ( ), a projectile ( ), a propellant charge igniter ( ) extending in the direction of the longitudinal axis of cartridge ( ) and arranged inside the cartridge case ( ), and an electrically programmable projectile fuse arranged in the projectile ( ) and connected via at least one electrical line ( ) to an electrode on the cartridge base ( ). The cartridge case ( ) comprises at least two case sections ( ) with at least one separation location in the region between the front end ( ) of the propellant charge igniter ( ) and the projectile tail ( ) for the installation of a section of the electrical line ( ) between the cartridge base ( ) and the projectile fuse using two rotating connector assemblies, one of which turns more easily than the other. One of the rotating connector assemblies is positioned on the propellant charge igniter and provided with a connection to the electrical line section that is oriented at an angle to the axis of rotation of the rotating connector assembly.

A cartridge includes a cartridge case having a cartridge base; a projectile having a rearward portion received by the cartridge case; a propellant primer disposed in the cartridge case and extending along the longitudinal cartridge axis; an electrically programmable projectile fuze disposed in the projectile; an electrode disposed at the cartridge base; a plug mounted on the propellant primer at a frontal end thereof; a first contact carried by the plug; a first conductor extending in the propellant primer and connecting the first contact with the electrode; a socket, formed on the rearward portion of the projectile, receives and surrounds the plug; a second contact carried by the socket and being in electric contact with the first contact; and a second conductor extending in the projectile and connecting the second contact with the projectile fuze.
