Ein im Längsschnitt dargestellter Splitterkörper 1 einer Infanteriegranate 5 besteht aus einem Topf 7 aus einem duktilen Stahl, einer darin angeordneten Sprengladung 9, und aus einem Kunststoffhemd 17 mit einem angeformten Führungsring 18. A fragmentary body 1 of an infantry grenade 5 is shown in longitudinal section from a pot 7 made of a ductile steel, an explosive charge arranged therein 9, and from a plastic shirt 17 with an integrally formed guide ring 18th

Der Splitterkörper 1 ist in zwei Längsabschnitte 25, 26 gegliedert.The splinter body 1 is divided into two longitudinal sections 25, 26.

Der vordere, öffnungsseitige Abschnitt 25 besteht aus innenseitig mit Kerben 27 versehenen Splitterringen 28 oder mit Kerben 27 versehenen Wendel 29 jeweils aus Stahl.The front, opening-side section 25 consists of notches 27 on the inside provided splinter rings 28 or with notches 27 provided helix 29 each Stole.

Im Längsabschnitt 26 sind in Kunststoff 31 gelagerte Kugelsplitter 32 vorgesehen.Ball splinters 32 supported in plastic 31 are provided in the longitudinal section 26.

Das Kunststoffhemd 17 liegt heckseitig in einer Ringnut 35 eines Rohransatzes 37 des Topfes 7. Dieser Rohransatz 37 lagert eine Leuchtspur 40. Weiterhin weist der Topf 7 öffnungsseitig einen radialen Bund 43 als Anschlag für den Splitterkörper 1 und einen dünnwandigen, mit Gewinde 45 versehenen dünnwandigen Kragen 47 auf. Ein Zünder 50 ist in das Gewinde 45 eingeschraubt und liegt axial an dem Bund 43 an.The plastic shirt 17 is located in the rear in an annular groove 35 of a tubular extension 37 of the pot 7. This tube extension 37 supports a tracer 40. Furthermore, the Pot 7 on the opening side a radial collar 43 as a stop for the splinter body 1 and a thin-walled, threaded 45 thin-walled collar 47 on. An igniter 50 is screwed into the thread 45 and lies axially on it Bund 43 on.

Der Sprengstoff 9 erstreckt sich über den radialen Bund 43 entsprechend einem Überstand 11 hinaus bis in den Bereich des Kragens 47. Dabei weist der Sprengstoff 9 eine zentrale, stirnseitige Bohrung 10 auf in die ein Zündverstärker 51 des Zünders 50 ragt.The explosive 9 extends over the radial collar 43 in accordance with a Protrusion 11 extends into the area of the collar 47. The explosive points 9 a central, frontal bore 10 into which an ignition amplifier 51 of the Zünder's 50 protrudes.

Die vorgekerbten Splitterringe 28 bzw. die vorgekerbte Wendel 29 weisen eine geringe radiale Höhe 30 auf, so daß einerseits in radialer Richtung wirksame Splitter erzeugbar sind, andererseits durch die geringe Höhe 30 der Splitterringe 28 bzw. Wendel 29 in radialer Richtung ein großes Sprengstoffvolumen für den Sprengstoff 9 ermöglicht ist.The pre-notched splinter rings 28 and the pre-notched coil 29 have one low radial height 30, so that on the one hand effective splinters in the radial direction can be generated, on the other hand by the small height 30 of the splinter rings 28 or coil 29 in the radial direction a large volume of explosives for the Explosives 9 is enabled.

In Längsrichtung 26 sind die Kugelsplitter 32 mehrlagig angeordnet, da hier ein größerer Verfügungsraum vorliegt.The ball splinters 32 are arranged in multiple layers in the longitudinal direction 26, since here one there is more available space.

Das Kunststoffhemd 17 hüllt ab dem vorderen Ende des Kragens 47 den gesamten Splitterkörper 1 ein und trägt wesentlich zur Abschußfestigkeit der Infanteriegranate 5 bei.The plastic shirt 17 envelops the entire from the front end of the collar 47 Splinter body 1 and contributes significantly to the firing strength of the infantry grenade 5 at.

Nach Zündung der Sprengladung 9 - ausgehend von dem Zündverstärker 51 - werden der Topf 7 - entsprechend der geometrischen Verteilung der Kerben 27 der Splitterringe 28 bzw. Wendel 29 und der Lage der Kugelsplitter 32 - im Sinne eines dadurch vorgegebenen Rasters - in Splitter zerlegt und zusammen mit den nicht dargestellten Einzelsplittern aus den Splitterringen 28 bzw. 29 und den Kugelsplittern 32 in radialer Richtung und heckseitig beschleunigt. Die Kugelsplitter 32 und die Kerben 27 der Splitterringe 28 bzw. der Wendel 29 bewirken eine Vorfragmentierung des Topfes 7.After ignition of the explosive charge 9 - starting from the ignition amplifier 51 - are the pot 7 - according to the geometric distribution of the notches 27 of the Splinter rings 28 or helix 29 and the position of the ball splinters 32 - in the sense of a thereby predetermined grid - broken down into fragments and together with the not individual fragments shown from the splinter rings 28 and 29 and the ball splinters 32 accelerated in the radial direction and at the rear. The ball splinters 32 and the notches 27 of the splinter rings 28 or of the helix 29 cause pre-fragmentation the pot 7.

Ebenso wird der Zünder 50 in Splitter zerlegt, da hier die Sprengladung 9 einerseits in eine Ausnehmung 53 des Zünders 50 ragt und andererseits die Sprengladung 9 den Zündverstärker 51 umgibt.The detonator 50 is likewise broken down into fragments, since here the explosive charge 9 is on the one hand protrudes into a recess 53 of the detonator 50 and on the other hand the explosive charge 9 surrounds the ignition amplifier 51.

Die Bohrung 10 mit ihrem kurzen zylindrischen Teil 12 und dem konisch sich öffnenden Teil 13 bewirken zusammen mit dem sprengstoffseitigen Ring 14 die reproduzierbare Zerlegung des Zünders 50. Dieser Ring 14 weist zum Umfang 15 der Sprengladung 9 einen freien Bund 16 auf. Möglicherweise erzeugt der Ring 14 in Verbindung mit dem konischen Teil 13 eine gerichtete Sprengwirkung zur Zerlegung des Zünders 50.The bore 10 with its short cylindrical part 12 and the conically opening Part 13 together with the explosive ring 14 cause the reproducible Disassembly of the detonator 50. This ring 14 faces the circumference 15 the explosive charge 9 has a free collar 16. Ring 14 may be producing in connection with the conical part 13 a directional explosive effect for disassembly the igniter 50.

Die Splitterwirkung besteht also aus vier Komponenten, nämlich aus den Stahlsplittern des Topfes 7, den Kugelsplittern 32, den Stahlsplittern der Splitterringe 28 bzw. der Wendel 29 und den Splittern des Zünders 50.The splintering effect consists of four components, namely the steel splinters the pot 7, the ball splinters 32, the steel splinters of the splinter rings 28 or the coil 29 and the splinters of the igniter 50.
