Patent number: 8561544Abstract: The invention relates to a projectile (1) having a sub-caliber projectile core (2) and a guide cage or sabot (3) that comprises a driving element (4), which acts on the projectile core (2) at the rear thereof and is in the form of a plate composed of metal. In order to produce such a projectile (1) at low cost, the projectile core (2) and the driving element (4), 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 (3) of the projectile (1) is produced after the injection-molding process.Type: GrantFiled: July 25, 2008Date of Patent: October 22, 2013Assignee: Rheinmetall Waffe Munition GmbHInventors: Christian Baumann, Holger Brase, Thomas Heitmann, Michael Vagedes

Patent number: 8297189Abstract: The invention relates to so-called fuze damping in projectiles, in particular, those provided with a built-in firing delay. Thus, a projectile (1) is provided having a rear part (1a) and a fuze (2), wherein at least one damping element (7) is inserted between a fuze base (5) and the projectile (1) and/or between a fuze shoulder (6) and a possible threaded ring (4), or similar attachment element. The damping element (7) is in the form of a disc, ring or pot, and is composed of a material with a lower acoustic impedance than the material of the projectile (1).Type: GrantFiled: November 16, 2009Date of Patent: October 30, 2012Assignee: Rheinmetall Waffe Munition GmbHInventors: Wolfgang Hoffmann, Wolfgang Scherge, Mathias Lengnick, Holger Brase, Stefan Kell, Torsten Niemeyer

Patent number: 6827206Abstract: A packaging container is provided for a large-caliber cartridge having a thin-walled cartridge case and a projectile, whose projectile head projects out of the front of and is connected to the cartridge case. The packaging container has an outer container and an inner container, which receives the cartridge. To secure the projectile of the cartridge inside the packaging container, with respect to a possible displacement of the projectile toward the rear end of the container, the projectile head of the cartridge is disposed in the inner container in a frictional lockup. For this purpose, the inner container has a one-piece projectile-head shaped receptacle at the front, to which a first half-shell that partially surrounds the cartridge case is connected, and a second half-shell, that is hinged to the first half-shell and can be secured to it.Type: GrantFiled: June 6, 2002Date of Patent: December 7, 2004Assignee: Rheinmetall W & M GmbHInventors: Holger Brase, Thomas Heitmann

Publication number: 20040084330Abstract: A packing case (1) for a large-caliber cartridge (2), having a thin-walled cartridge case (3) and a projectile (4), which protrudes at least partially out of the front of the cartridge casing (3), and has at its outer circumference an annular stop groove (5), with the packing case (1) including an outer case (6) and an inner case (7) that comprises at least two partial cases disposed one behind the other. To enable the cartridge to be easily secured in the packing case and subsequently removed, at least two spring-loaded stop elements (19) that can pivot toward the projectile (4) and have guide elements (21) are provided. The stop elements extend with a form-fit into the stop groove (5) of the projectile (4) and are supported at the rear against a partial case (11) of the inner case (7).Type: ApplicationFiled: October 27, 2003Publication date: May 6, 2004Applicant: Rheinmetall W & M GmbHInventors: Lutz Borngen, Holger Brase, Silvia Bruske, Thomas Heitmann, Michael Vagedes, Martin Berg

Publication number: 20020185386Abstract: A packaging container (1) for a large-caliber cartridge (2) having a thin-walled cartridge case (3) and a projectile (5), whose projectile head (6) projects out of the front of and is connected to the cartridge case (3), with the packaging container (1) including an outer container (7) and an inner container (8), which receives the cartridge. To secure the projectile (5) of the cartridge (2) inside the packaging container (1), with respect to a possible displacement of the projectile (5) toward the rear end of the container when the projectile is a full-caliber projectile (5) whose projectile head (6) has a smooth surface, the projectile head (6) of the cartridge (2) is disposed in the inner container (8) in a frictional lockup.Type: ApplicationFiled: June 6, 2002Publication date: December 12, 2002Inventors: Holger Brase, Thomas Heitmann
