Abstract: A sabot for a subcaliber projectile, preferably an arrow projectile, having an essentially cylindrical guide gage (8) of a lightweight material and a tail-side drive element (14) detachably connected thereto for tail-side support of the projectile body (1). The guide cage (8) has a radially inwardly-extending support wall (12) for supporting a projectile body (1) disposed therein in its forward to central region, and the drive element is a propelling disk (14) that is received by a circumferential or annular groove (13) in the tail region of the guide cage (8), which is segmented in the axial direction of the projectile body (1). As a result, a further reduction in weight can be accomplished with simpler fragmenting of the sabot that practically does not impair the projectile at all.

Abstract: A casing bottom or stub casing for a propelling charge casing whose base plate (1) has an exterior or outer surface which is curved inwardly in an annular region (7) so that the casing bottom is able to sufficiently axially expand under the high gas pressure developing during firing without requiring the use of a high strength material.

Abstract: A subcaliber kinetic energy projectile (1) including a penetrator (2) and a segmented sabot (3) which is provided with a front support (4) and with a second support (5) that is disposed at an axial distance behind the first support, with the second support (5) including a rotationally symmetrical air pocket (6) that faces the first support (4) and the first support (4) is provided with air passage openings (43, 44, 45).In the sabot, the relationship of L/D.gtoreq.1.2 exists between the length L of the penetrator tip (8) ahead of the first support (4) and the caliber D. The relationship x.gtoreq.0.45 * .iota. further applies between the distances x and .iota., with x being the distance between the trailing edge (10) of the sabot and the base surface (11) of the air pocket (6) in the second support (5) and .iota. being the distance between the trailing edge (10) of the sabot (3) and the leading edge (12) of the sabot at the surface of the penetrator (2).

Abstract: A casing bottom for a propelling charge including a circular ring shaped (annular) base plate (1) which accommodates a centrally arranged primer sleeve (7) in a form-locking manner. In order to be able to unload ammunition, particularly two-part ammunition including sub-caliber projectiles, the rear surface of the primer sleeve is provided with a recess for form-fittingly receiving an extractor. Preferably the recess is of a size which can be accommodated on a sub-caliber projectile.

Abstract: A subcaliber projectile including a segmented discardable propelling cage sabot which encloses at least a portion of the projectile body and has a common form-locking zone for the transfer of acceleration forces from the propelling cage to the projectile body. The form-locking zone has mating annular grooves and counter grooves on the exterior surface of the projectile body and on the interior surface of the propelling cage, and is subdivided into several form-locking zone regions in which the annular grooves have a different groove spacing that is adapted to the locally occurring shear stresses. These measures enhance simplification of the manufacturing process and result in an improvement of the release of the propelling cage sabot from the projectile body and in an increase in the target impact velocity of the projectile body.

Abstract: To provide a complete seal in the region of the rifling, particularly in worn-out gun barrels firing spin stabilized carrier projectiles provided with a metal guide or driving band and a thin-walled projectile connected to a projectile base and having a wall thickness less than or equal to 0.05 times the caliber of the gun barrel and to reduce the ramming deceleration and the radial pressure stresses on the projectile shell during passage through the gun barrel, a plastic ram ring is disposed on the outer surface of the projectile shell in front of the metal guide band and in a region of the shell that is not supported radially by the projectile base.

Abstract: A projectile arrangement including a subcaliber projectile body and a segmented, discardable propelling cage sabot provided with a common form locking zone for the transmission of the acceleration forces. To reduce the notch effect on the projectile body, and thus the danger of breakage, due to the conventional thread grooves in the form locking zone, particularly in long, slender penetrators made of a breakage susceptible tungsten heavy metal, a novel form locking connection for the inner form locking region between the propelling cage and the projectile body is provided. This novel form locking connection is characterized in that in the region of the form locking zone beneath the exterior gas pressure receiving surface of the sabot, only the exterior surface of the projectile body is provided with preferably annular microgrooves and the surrounding inner surface of the sabot is smooth.

Abstract: In projectile bases (20) for carrier projectiles which are equipped with a cavity (26) on the side facing away from the projectile tail for, for example, a parachute, it may happen that the base plate (23) is axially bent through during firing. This causes the base body (22) to be radially constricted and contact is lost between the rotating band (27) disposed on the body (22) and the gun tube, frequently resulting in a gas breakthrough. To avoid the above-mentioned radial constriction in the region of the rotating band, the projectile base (20) is provided with a base plate (23) which is curved toward the tail of the projectile. The curved configuration of the base plate (23) makes it possible to produce radial widening in the rear projectile base region during firing so as to ensure gas tightness and spin transmission from the rotating band (27) even at high gas pressures.

Abstract: A segmented, discardable sabot for a slender sub-caliber kinetic energy projectile. At least two sabot segments are provided having adjacent plane parallel segment separating faces and presenting at least one caliber-sized gas sealing pressure flange member and a non-caliber sized partial region along the longitudinal extent of the sabot. The overall cross section of the sabot, at least in the partial region, has an essentially polygonal cross-sectional shape, and a tangent placed at any point of the periphery of the sabot does not pass through the cross-sectional area of the sabot, thereby providing increased bending stiffness in the non-caliber-sized region of the sabot.

Abstract: A high-explosive projectile including a projectile body having a forward region and a tail region which transitions to a base, with an explosive charge disposed within the body and detonated by a suitable fuse, and a driving band disposed on the outer circumferential surface of the projectile body in the tail region, wherein the wall thickness of the tail region of the projectile body is substantially the same as the wall thickness of the forward region of the projectile body; the tail region of the projectile body has a cylindrical shape up to its transition to the base and forms a circumferential edge at the transition; and the rearward, gas pressure receiving side of the driving band is disposed adjacent the circumferential edge.

Abstract: The present invention relates to a spin-stabilized carrier projectile having a projectile base which is connected with a projectile body for carrying sub-ammunition projectiles, and a driving band arrangement connected respectively about the projectile base and about the projectile body for engaging the rifling of the gun barrel to impart spin respectively to the projectile base and the projectile body. The driving band arrangement includes a first partial driving band connected coaxially about the projectile base and a second partial driving band connected coaxially about the projectile body. This driving band arrangement reduces the spin forces transferred by the joint between the projectile base and the projectile body, thereby reducing the required joint strength. This in turn reduces the required ejection charge used to separate the projectile body and projectile base for release of sub-ammunition bodies contained in the carrier projectile.

Abstract: A spin stabilized projectiles (1) having a rotating band (3) arranged on the shell body (2), with such rotating band being provided with grooves (35, 36, 37) to receive rotating band material sheared off toward the rear during passage of the projectile (1) through a gun barrel (4) so that the transfer of spin is effected with the aid of annular rotating band zones (31, 32, 33, 34) which form spin transfer ring. The diameter (38) of at least one spin transfer ring (31, 34), preferably the rearmost ring, is larger than the diameter (45) of the rifling grooves (42) in the gun barrel (4). Due to the high radial pressure on the shell body in the region of the rotating band, great radial deformations may occur, particularly in thin-walled shell bodies. The consequences are untightness of the rotating band and too much stress on the projectile.
