Patent number: 7114449Abstract: A method for producing a large-caliber, high-explosive projectile (1, 1?), and a projectile formed according the method, having a projectile casing (2, 2?) that surrounds a chamber (6, 6?) filled with an explosive charge (9, 9?), and that has a mouth (5, 5?) at its tip that can be sealed, and through which the explosive charge (9, 9?) is inserted into the chamber (6, 6?) of the high-explosive projectile (1, 1?). The explosive charge (9, 9?) is disposed in a plastic casing (8), comprised of an elastic material, inside the chamber of the high-explosive projectile (1, 1?). Additional tensioning means (11, 11?, 17, 17?) are provided to compensate for the varying volume of the explosive charge (9, 9?) relative to the projectile casing (2, 2?) if the temperature fluctuates dramatically and maintain the explosive charge (9, 9?) under a pre-stress, particularly when using a plastic bound explosive charge (9, 9?).Type: GrantFiled: September 30, 2004Date of Patent: October 3, 2006Assignee: Rheinmetall W & M GmbHInventor: Ernst-Wilhelm Altenau

Patent number: 5090326Abstract: A lightweight training bomblet provided with a housing made of cardboard or plastic. Such training bomblet should be easily assembled and be able to withstand the high acceleration forces generated during transport into a target area. To prevent undue deformations of the bomblet housings made, for example, of cardboard, during air transport and the resulting premature ignition during ejection from a carrier projectile, both cardboard or plastic housing covers are connected with one another by means of a pre-tensioned connecting arrangement and their abutment faces are pressed against the end faces of a tubular housing shell, with the abutment faces of the housing covers possibly additionally containing a holding and sealing arrangement which is pressed into or against the end faces of the housing shell.Type: GrantFiled: January 17, 1991Date of Patent: February 25, 1992Assignee: Rheinmetall GmbHInventors: Ernst-Wilhelm Altenau, Ulf Hahn, Siegmar Fischer, Margret Palten

Patent number: 5076171Abstract: A bomblet carrier projectile for delivering training bomblets to a target area. A plurality of training bomblets are supported in layers within the projectile body, with each training bomblet having a housing made of at least one of paper and plastic. A plurality of supporting elements are disposed within the projectile body and stackable in the axial direction of the projectile body for supporting the training bomblet housings in the layers. A detonator is arranged in a frontal region of the projectile body. A gas passage channel is formed along the longitudinal axis of the projectile body. An ejector unit is disposed behind the detonator and includes an ejection charge for emitting ignition gases when ignited by the detonator that are passed through the gas passage channel for igniting the training bomblets and an ejection plate for ejecting the training bomblets from the projectile body, over a target area, in response to pressure generated by the ignition gases.Type: GrantFiled: October 15, 1990Date of Patent: December 31, 1991Assignee: Rheinmetall GmbHInventors: Ernst-Wilhelm Altenau, Siegmar Fischer, Margret Palten

Patent number: 4770100Abstract: The projectile body of a hollow charge subsidiary projectile is configured of a helical wire which forms a closed wall in that mutually adjacent wire turns are connected together in common contracting regions. A given number of wire turns at the front of the projectile body beginning in the vicinity of the base of the hollow charge insert remain unconnected so that a spring-like detonator spacer results which is delimited at the front by the last wire turn.Type: GrantFiled: July 16, 1987Date of Patent: September 13, 1988Assignee: Rheinmetall GmbHInventors: Friedhelm Gunthner, Ernst-Wilhelm Altenau

Patent number: 4524696Abstract: An explosive shrapnel shell has a bursting charge having a front end, a layer of shrapnel laterally surrounding the charge except at the end, a fuse mounted on the front end, and shrapnel in the fuse. The fuse includes a detonator charge lying between the fuse shrapnel and the bursting charge. The shell is generally centered on an axis extending through the front end and the fuse includes an axially rearwardly extending tube. The detonator charge is in and axially behind the tube and the fuse shrapnel form a ring circumferentially surrounding the tube. An intensifying charge can lie between the detonator charge and the bursting charge.Type: GrantFiled: July 5, 1983Date of Patent: June 25, 1985Assignee: Rheinmetall GmbHInventors: Ernst-Wilhelm Altenau, Ulf Hahn, Udo Sabranski

Patent number: 4305333Abstract: Warhead for projectiles and rockets in which the projectile or rocket casing can be relied upon to decompose into splinters of predetermined size, shape, and distribution. To accomplish this result, a thin-walled insert is positioned between the projectile or rocket casing and the explosive charge, such insert being provided with a number of ribs forming a series of saddle-roof shaped structures which exert a cutting charge effect on the casing on the detonation of the explosive charge.Type: GrantFiled: August 10, 1979Date of Patent: December 15, 1981Assignee: Rheinmetall GmbHInventors: Ernst-Wilhelm Altenau, Wolfram Witt
