Gemäss Fig.1 weist das Geschoss 10 einen napfförmigen Splittermantel 11 auf. Dieser Splittermantel 11 besitzt einen Boden 12, der am hinteren Ende eines hülsenförmigen Körpers 13 angeordnet ist. Der hintere Teil 14 des hülsenförmigen Körpers 13 besitzt einen kleineren Innendurchmesser als der vordere Teil 15, d.h. die Wand des hinteren Teiles 14 ist dicker als die Wand des vorderen Teiles 15, und der Boden 12 ist dicker als die Wand des hinteren Teiles. Dieser Splittermantel 11 wird aus einer Scheibe 11′ hergestellt, die in Fig.2 und 3 dargestellt ist und die in Fig.1 in strichpunktierten Linien angedeutet ist. Entsprechend dem herzustellenden Splittermantel 11 besitzt diese Scheibe 11′ einen inneren Teil 12′, dessen Dicke der Dicke des Bodens 12 entspricht, einen mittleren ringförmigen Teil 14′, dessen Dicke der Dicke des hinteren Teiles 14 des hülsenförmigen Körpers 13 entspricht und einen äusseren ringförmigen Teil 15′, dessen Dicke der Dicke des vorderen Teiles 15 des hülsenförmigen Körpers 13 entspricht. Somit ist der innere Teil 12′ dicker als der mittlere Teil 14′ und dieser ist dicker als der äussere Teil 15′.According to FIG. 1, the projectile 10 has a cup-shaped fragment jacket 11. This fragment jacket 11 has a bottom 12 which is arranged at the rear end of a sleeve-shaped body 13. The rear part 14 of the sleeve-shaped body 13 has a smaller inner diameter than the front part 15, ie the wall of the rear part 14 is thicker than the wall of the front part 15 and the bottom 12 is thicker than that Wall of the rear part. This fragment jacket 11 is made from a disc 11 ', which is shown in Fig.2 and 3 and which is indicated in Fig.1 in dash-dotted lines. According to the splinter jacket 11 to be produced, this disc 11 'has an inner part 12', the thickness of which corresponds to the thickness of the base 12, a central annular part 14 ', the thickness of which corresponds to the thickness of the rear part 14 of the sleeve-shaped body 13 and an outer annular part 15 ', the thickness of which corresponds to the thickness of the front part 15 of the sleeve-shaped body 13. Thus, the inner part 12 'is thicker than the middle part 14' and this is thicker than the outer part 15 '.

Die eine Seite der Scheibe 11 ist mit Rillen 16 versehen. Die Form dieser Rillen ist aus Fig.6 und Fig.7 besser ersichtlich. Gemäss Fig.6 haben diese Rillen 16 einen dreieckigen Querschnitt und gemäss Fig.7 gibt es Längsrillen 16′ und Querrillen 16˝. Die mit Rillen 16 versehene Seite der Scheibe 11′ gelangt nach der Umformung der Scheibe 11′ in den Splittermantel 11 auf die Innenseite des Splittermantels 11. Die Umformung der Scheibe 11′ in den Splittermantel 11 erfolgt in üblicher an sich bekannter Weise insbesondere durch Tiefziehen. Das Geschoss 10 enthält eine Sprengladung 17 im Innern des Splittermantels 11. Diese Sprengladung 17 wird durch einen Kopfzünder 18 gezündet. Dieser Kopfzünder 18 ist in ein Innengewinde 19 des Splittermantels 11 eingeschraubt. Eine Verstärkerladung 20 am hinteren Ende des Kopfzünders 18 ragt ins Innere der Sprengladung 17.One side of the disc 11 is provided with grooves 16. The shape of these grooves can be seen better in FIGS. 6 and 7. According to Figure 6, these grooves 16 have a triangular cross section and according to Figure 7 there are longitudinal grooves 16 'and transverse grooves 16˝. The side of the disk 11 'provided with grooves 16' comes after the shaping of the disk 11 'into the splinter jacket 11 on the inside of the splitter jacket 11. The shaping of the disk 11' in the splitter jacket 11 is carried out in a conventional manner, in particular by deep drawing. The projectile 10 contains an explosive charge 17 inside the fragment jacket 11. This explosive charge 17 is ignited by a head detonator 18. This igniter 18 is screwed into an internal thread 19 of the splinter jacket 11. An amplifier charge 20 at the rear end of the detonator 18 projects into the interior of the explosive charge 17.

Gemäss Fig.4 weist das Geschoss 21 ebenfalls einen napfförmigen Splittermantel 22 auf. Dieser Splittermantel 22 besitzt eine Spitze 23, welche einen hülsenförmigen Körper 24 vorne abschliesst. Auch dieser Splittermantel 22 ist vorne an der Spitze 23 dicker als am hinteren Ende und auch dieser Splittermantel 22 wird aus einer Scheibe 22′ hergestellt, welche im mittleren Teil 23′ - der die Spitze 23 bildet - ebenfalls entsprechend dicker ist. Diese Scheibe 22′ weist gemäss Fig.5 an ihrer unteren Seite Längs- und Querrillen 16′ und 16˝ auf, wie weiter oben bereits beschrieben, siehe Fig.6 und Fig.7. In den Splittermantel 22 ist hinten ein Bodenzünder 25 eingeschraubt, der eine Verstärkerladung 26 aufweist, welche ins Innere einer Sprengladung 27 hineinragt, die sich im Splittermantel 22 befindet. Im Gegensatz zum ersten Ausführungsbeispiel ist der hülsenförmige Teil 24 vorne und hinten gleich dick. Somit ist auch die Scheibe 22 nur in einen mittleren dickeren Teil 23′ und in einen dünneren äusseren Teil 24′ unterteilt. Bei diesem Ausführungsbei spiel mit Bodenzünder 25 statt mit einem Kopfzünder 18 ist eine ballistische Haube 28 erforderlich. Diese ballistische Haube 28 ist gemäss Fig.4 nur auf die glatte Oberfläche des Splittermantels 22 aufgesetzt. Falls eine genauere Befestigung erforderlich ist, kann im Splittermantel eine zusätzliche Rille vorhanden sein, wie anhand von Fig.8 weiter unten beschrieben ist.According to FIG. 4, the projectile 21 likewise has a cup-shaped fragment jacket 22. This fragment jacket 22 has a tip 23, which is a sleeve-shaped Body 24 closes at the front. This fragment jacket 22 is thicker at the front at the tip 23 than at the rear end and this fragment jacket 22 is made from a disc 22 ', which in the middle part 23' - which forms the tip 23 - is also correspondingly thicker. This disc 22 'has according to Figure 5 on its lower side longitudinal and transverse grooves 16' and 16˝, as already described above, see Fig.6 and Fig.7. At the back, a base igniter 25 is screwed into the fragment jacket 22, which has an amplifier charge 26 which projects into the inside of an explosive charge 27 which is located in the fragment jacket 22. In contrast to the first exemplary embodiment, the sleeve-shaped part 24 has the same thickness at the front and rear. Thus, the disc 22 is only divided into a middle thicker part 23 'and a thinner outer part 24'. In this game Ausführungsbei with floor igniter 25 instead of a head igniter 18, a ballistic hood 28 is required. According to FIG. 4, this ballistic hood 28 is only placed on the smooth surface of the splinter jacket 22. If a more precise fastening is required, an additional groove can be present in the splinter jacket, as described below with reference to FIG. 8.

Gemäss Fig.8 und 9 weist das Geschoss 29 einen napfförmigen Splittermantel 30 auf. Dieser Splittermantel 30 unterscheidet sich durch folgende Merkmale gegenüber dem in Fig.4 dargestellten und weiter oben beschriebenen Geschoss 21. Zur Befestigung einer ballistischen Haube 31 ist im Splittermantel 30 eine Umfangsrille 32 angeordnet. Der Splittermantel 30 weist nicht nur eine wesentlich dickere Spitze 33, sondern auch einen dickeren hülsenförmigen Abschnitt 34 auf. Dazwischen befindet sich ein mittlerer, dünnerer Abschnitt 36. Entsprechend ist auch die Scheibe 30′ anders ausgebildet. Diese Scheibe 30′ ist in einen inneren, dickeren Teil 33′, einen mittleren, dünneren Teil 36′ und in einen äusseren, dickeren ringförmigen Teil 34′ unterteilt.According to FIGS. 8 and 9, the projectile 29 has a cup-shaped splinter jacket 30. This splinter jacket 30 differs from the projectile 21 shown in FIG. 4 and described above by the following features. A peripheral groove 32 is arranged in the splinter jacket 30 for fastening a ballistic hood 31. The splinter jacket 30 not only has a much thicker tip 33, but also a thicker sleeve-shaped section 34. In between there is a middle, thinner section 36 also the disc 30 'formed differently. This disc 30 'is divided into an inner, thicker part 33', a middle, thinner part 36 'and an outer, thicker annular part 34'.

In Fig.10 ist eine Scheibe 37′ mit den durch Rillen 38′,38˝ gebildeten Sollbruchstellen dargestellt. Das Muster dieser Rillen ist so gewählt, dass beim Umformen der Scheibe 37′ in einen Splittermantel regelmässige Sechsecke beziehungsweise Vierecke entstehen.In Figure 10, a disc 37 'is shown with the predetermined breaking points formed by grooves 38', 38˝. The pattern of these grooves is chosen so that regular hexagons or quadrilaterals are formed when the disk 37 'is formed into a splinter jacket.

Die radialen Rillen 38˝ werden vorzugsweise weniger tief in die Scheibe 37′ eingeprägt als die ringförmigen Rillen 38′. Dies hat den Vorteil, dass durch die unterschiedliche Einprägetiefe der Rillen 38′ und 38˝ ein gleichmässiger Zerfall des Splittermantels in Bruchstücke der gewünschten Grösse erreicht wird.The radial grooves 38˝ are preferably impressed less deeply into the disk 37 'than the annular grooves 38'. This has the advantage that a uniform disintegration of the splinter jacket into fragments of the desired size is achieved by the different embossing depth of the grooves 38 'and 38˝.
