Patent number: 5438930Abstract: The invention relates to a mine with at least one ejectable sub-munitions body disposed in a cup-shaped starting device and with a propulsion device for propelling the sub-munitions body into a selectable altitude range. For achieving that the propulsion device requires only a small structural volume, entails low cost because of the use of reduced amounts of propulsion charges and in addition operates safely and dependably. It has been proposed to dispose the propulsion device not in or on the sub-munitions body, but in the bottom part of the cup-shaped starting device. In this case the propulsion device advantageously consists of a high pressure chamber facing the bottom of the starting device, in which the propellant charge is contained, and of a low pressure chamber facing the sub-munitions body. The high pressure and low pressure chambers are separated from each other by a perforated plate provided with jets (holes).Type: GrantFiled: September 7, 1994Date of Patent: August 8, 1995Assignee: Rheinmetall GmbHInventors: Werner Grosswendt, Klaus Gersbach, Joachim Fiebrich

Patent number: 4747191Abstract: A sabot arrangement is produced in accordance with an improved manufacturing method. The sabot arrangement includes a rotational symmetrical sabot body having a central axial bore and radial separating grooves or slots. The radial grooves or slots divide the sabot body into a plurality of equal segments. These slots nearly sever the sabot body into separate segments, so that a material bridge remains near a forward edge and a material bridge remains near a rear edge of the sabot body, which material bridges function as fracture zones.Type: GrantFiled: September 16, 1985Date of Patent: May 31, 1988Assignees: Rheinmetall GmbH, L'Etat Francais represente par le Delegue General pour l'ArmementInventors: Patrick Montier, Pierre A.

Patent number: 4714024Abstract: An improved nose construction for a subcaliber inertial projectile which is ired with the aid of a sabot. A hood or body is mounted on the nose portion of the projectile. The hood is made of synthetic material and includes longitudinally extending fracture zones and is of substantially cylindrical shape. The frontal portion of the hood is recessed and forms an air flow receiving surface. In lieu of a hood a body, made of a thermoplastic material or the like, may be mounted on the nose portion. This body is adapted to disintegrate as result of air friction. The presence of the hood or body on the nose portion of the projectile, as it exits from a non-illustrated gun barrel, avoids or at least reduces unfavorable air-streaming forces which destabilize the flight characteristics of the projectile and thereby favors a uniform separation of the sabot segments from the projectile. Such uniform separation reduces or completely eliminates undesirable oscillations during flight of the projectile.Type: GrantFiled: June 13, 1986Date of Patent: December 22, 1987Assignees: Rheinmetall GmbH, L'Etat Francais represente par le Delegue Ministeriel pour l'ArmementInventors: Jurgen Bocker, Klaus W.

Patent number: 4677915Abstract: A sub-caliber armor-piercing projectile exhibits for improving its penetration effect against a strongly inclined target surface a break-up in the region of a fracture zone of an expendable nose portion. The latter is provided at its point region with an arrangement which favors a sliding-off, which arrangement includes at least two frusto-conical surfaces which encompass the longitudinal projectile axis A and which surfaces are differently inclined with respect to the longitudinal axis of the projectile or include a sphere disposed in a spherical recess. The arrangement can be cladded with a ballistic hood and can be provided in the region of the frusto-conical or the spherical surfaces with a lubricating medium. The fracture zone is constructed in such a way that when a deviating sliding-off of the arrangement occurs, as large as possible a twisting impulse is transferred under the main projectile portion in order to improve its penetration capability by means of a more favorable penetrating angle.Type: GrantFiled: June 25, 1984Date of Patent: July 7, 1987Assignee: Rheinmetall GmbHInventors: Juegen Boecker, Klaus Gersbach, Karl W.

Patent number: 4624187Abstract: A nose unit for a discarding sabot penetrator having a bolt in a bore of the pointed nose which is temporarily displaced on firing due to acceleration and against a restoring spring. This produces a circular edge and a break in the contour of the nose to define a limit surface between a zone of supersonic airflow and a zone of subsonic airflow, at least during the separation of the sabot segments. This facilitates the uniformed detachment of the segments.Type: GrantFiled: September 10, 1985Date of Patent: November 25, 1986Assignee: Rheinmetall GmbHInventors: Jurgen Bocker, Klaus Gersbach, Klaus W. Klein

Patent number: 4542696Abstract: A munitions round for a subcaliber projectile to be fired from a barrel-type weapon has a casing, of a uniform outer cross section substantially over its entire length, receiving the projectile which is at least partially surrounded by the gas-generating propellant charge. A drive body is mounted at the forward end of the projectile and has a rearward pressure-receiving surface which droops inwardly toward the projectile from an outer edge of the body which is engaged by the casing. The body is formed from a plurality of segments which form-fittingly hug the projectile and have confronting angularly spaced separating surfaces bridged by a sealing member. The forward end of the body, formed by the segments, is concave forwardly and has a leading edge which is disposed outwardly and axially ahead of the rearward inner edge of this surface which forms a pocket engaging the air upon propulsion of the projectile from the barrel to effect separation of the segments and dislodgment of the body.Type: GrantFiled: November 1, 1983Date of Patent: September 24, 1985Assignee: Rheinmetall GmbHInventors: Bernhard Bisping, Peter Wallow, Klaus Gersbach, Rudolf Romer
