Description

Die Erfindung bezieht sich auf ein Splittergeschoß mit Bodenzünder und Treibladungshülse nach dem Oberbegriff des Anspruches 1. Es handelt sich um ein ballistisches Geschoß.The invention relates to a fragmentary projectile with a ground igniter and propellant charge case according to the preamble of claim 1. It is a ballistic Bullet.

Ein vollständig im Geschoßkörper integrierter Zünder ist aus der US-A-4 216 722 bekannt. Dieser Geschoßkörper ist Bestandteil eines aufpilzbaren Polizeigeschosses. Die in einer Explosionskammer angeordnete Sprengstoffmenge bewirkt ein Aufspreizen des vorderen Geschoßkörpers. Der Geschoßkörper wird daher nicht in Einzelsplitter zerlegt.A detonator fully integrated in the projectile body is from US-A-4 216 722 known. This projectile body is part of a mushroomable police bullet. The amount of explosives arranged in an explosion chamber causes a Spread the front floor body. The bullet body is therefore not broken down into individual fragments.

Bei einem flügelstabilisierten Artilleriegeschoß nach der DE-PS 89 235 sind in einer heckseitigen Ausnehmung eine Sprengladung und ein Bodenzünder angeordnet. Der Zünder ist kurzbauend und ist auf dem Prinzip einer Revolverpatrone aufgebaut, was heute aufgrund der Sicherheitsvorschriften nicht mehr zulässig ist. Aufgrund des kurzbauenden Bodenzünders ist die Länge des Sprengstoffes in bezug auf den Zünder sehr groß.In a wing-stabilized artillery shell according to DE-PS 89 235 are in an explosive charge and a ground detonator are arranged in a rear recess. The detonator is short and is based on the principle of a revolver cartridge built up what is no longer permitted due to the safety regulations. Due to the short base detonator, the length of the explosive is in very large in relation to the detonator.

Bei einem Durchschlagsgeschoß nach der US-H 1 235 beträgt die Länge des Bodenzünders innerhalb des Splittermantels in bezug auf die Länge des Sprengstoffs etwa 60%.In the case of a penetration projectile according to US Pat. No. 1,235, the length of the base igniter is within the splinter jacket with respect to the length of the explosive about 60%.

Bei einem Artilleriegeschoß entsprechend der DE-PS 21 172 ist ein kurzbauender Bodenzünder vorgesehen, der zu seinem größten Teil innerhalb des Splittermantels liegt. In an artillery projectile according to DE-PS 21 172 is a short construction Ground igniter provided, for the most part within the splinter jacket lies.

Bei einem Artillerie-Splittergeschoß nach der US 4 882 996 benötigt ein Bodenzünder nur einen Bruchteil der für die Sprengladung vorgesehenen Länge des Splittermantels. Der Hauptanteil des Zünders liegt außerhalb des Splittermantels. Bei Artilleriegeschossen ist die Treibladung bekanntlich getrennt vom Artilleriegeschoß, d.h., die Ladungen werden dem Geschütz getrennt vom Artilleriegeschoß zugeführt. Eine Treibladungshülse wird daher nicht verwendet. Dies bedeutet, daß entsprechend den Gegebenheiten in einem Geschütz im heckseitigen Bereich des Geschosses genügend Raum für einen Zünder vorhanden ist.In the case of an artillery fragmentary projectile according to US Pat. No. 4,882,996, a ground igniter is required only a fraction of the length of the explosive charge Sliver sheath. The main part of the detonator is outside the splinter jacket. As is known, the propellant charge on artillery shells is separate from the artillery shell, i.e. the charges are separated from the artillery projectile fed. A propellant charge case is therefore not used. This means that according to the circumstances in a gun in the rear area of the There is enough space for a detonator.

Bei patronierten Geschossen, also Geschossen mit daran angeordneten Treibladungshülsen, steht aufgrund der Gegebenheiten der Treibladungshülse ein nur geringes Volumen für den Zünder zur Verfügung.In the case of cartridge bullets, i.e. bullets with propellant charge sleeves arranged on them, is due to the circumstances of the propellant charge only a small one Volume available for the detonator.

Der Erfindung liegt die Aufgabe zugrunde, ein Splittergeschoß mit Treibladungshülse zu schaffen, das eine verbesserte Wirkung im Ziel aufweist.The invention is based, a fragmentary projectile with propellant charge shell the task to create that has an improved effect on the target.

Diese Aufgabe wird entsprechend den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This task is in accordance with the characterizing features of the claim 1 solved.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the subclaims.

Durch die erfindungsgemäße Ausbildung des Splittergeschosses mit einem, über das hintere Ende des Splittermantels hinaus verlängerten Geschoßzünder ergeben sich drei verschiedene Optimierungsmöglichkeiten der Geschoßleistung, und zwar Verbesserung der Durchschlagsleistung durch Massevergrößerung des Geschoßkopfes, Optimierung der wirksamen Splitter durch eine Vergrößerung der Wanddicke der Splitterhülse bei Beibehaltung des üblichen Sprengstoffanteils oder Vergrößerung des Sprengstoffanteils bei Beibehaltung der üblichen Dicken von Geschoßspitze und Wandung der Splitterhülle.Due to the inventive design of the fragmentary floor with a, about the extended end of the splinter jacket results in extended projectile detonators there are three different ways to optimize floor performance, namely Improvement of the penetration performance by increasing the mass of the projectile head, Optimization of the effective splinters by increasing the wall thickness the splinter sleeve while maintaining the usual amount of explosives or enlargement the proportion of explosives while maintaining the usual thicknesses of the tip of the projectile and wall of the splinter shell.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigt in der einzigen Figur einen Längsschnitt durch eine patronierte Munition. An embodiment of the invention is shown in the drawing. It shows in the single figure a longitudinal section through a cartridge ammunition.

Ein Splittergeschoß 1 mit einem Kaliber 30 mm besitzt einen Bodenzünder 2, ein Führungsband 3 und ist mit einer Treibladungshülse 4 verbunden.A fragmentary bullet 1 with a caliber of 30 mm has a base igniter 2, one Guide belt 3 and is connected to a propellant charge sleeve 4.

Ein Teil einer Geschoßogive 10 ist als massiver Durchschlagskern 12 ausgebildet. An den Durchschlagskern 12 mit einer Länge 14 schließt sich heckseitig eine Ausnehmung 16 mit einer Länge 18 an. Die Ausnehmung 16 ist in einen konischen und in einen zylindrischen Abschnitt 20, 22 gegliedert. Diese Abschnitte 20, 22 stellen den Splittermantel 24 dar.Part of a storey log 10 is designed as a solid breakdown core 12. At the punch core 12 with a length 14 a recess closes at the rear 16 with a length of 18. The recess 16 is in a conical and divided into a cylindrical section 20, 22. Make these sections 20, 22 the fragment jacket 24.

Am Splittermantel 24 ist eine Nut 26 für die angewürgte Treibladungshülse 4 und eine Gewindeverbindung 5 für den Bodenzünder 2 vorgesehen. Das vordere Ende der Treibladungshülse 4 ist mit 30 bezeichnet und liegt in einem Abstand 31 vom hinteren Ende 36 des Splittermantels 24 bzw. der Ebene 34. Dieser Abstand 31 beträgt etwas weniger als 1/3 des Kalibers 32.On the splinter jacket 24 there is a groove 26 for the choked propellant charge sleeve 4 and a threaded connection 5 is provided for the ground igniter 2. The front end the propellant charge sleeve 4 is designated 30 and is at a distance 31 from rear end 36 of the splinter jacket 24 or the plane 34. This distance 31 is a little less than 1/3 of the caliber 32.

Der Bodenzünder 2 besitzt eine Gesamtlänge 50 mit zwei etwa gleichgroßen Teillängen, nämlich einer inneren Teillänge 52 und einer äußeren Teillänge 54.The ground igniter 2 has a total length 50 with two approximately the same size Partial lengths, namely an inner partial length 52 and an outer partial length 54.

Der Bodenzünder 2 weist weiterhin einen zylindrischen Abschnitt 56 mit einem Dämpfungskörper 57, ein zapfenförmiges Gehäuse 60 für eine nicht dargestellte Verstärkungsladung entsprechend der Teillänge 52 und einen konischen Anschlagsbund 62 mit einem heckseitigen, konischen Zapfen 64 entsprechend der äußeren Teillänge 54 auf.The ground igniter 2 also has a cylindrical section 56 with a Damping body 57, a peg-shaped housing 60 for a not shown Booster charge corresponding to partial length 52 and a conical stop collar 62 with a rear conical pin 64 corresponding to the outer partial length 54.

Der Anschlagsbund 62 und der Zapfen 64 liegen innerhalb der Treibladungshülse 4 mit geschütteter Ladung 66 im Ladungsraum 68, also außerhalb des Splittermantels 24. Die Ladung 66 füllt den Ladungsraum 68 vollständig aus.The stop collar 62 and the pin 64 lie within the propellant charge sleeve 4 with poured cargo 66 in the cargo space 68, that is, outside the splinter jacket 24. The cargo 66 completely fills the cargo space 68.

Eine Sprengladung 70 füllt die Ausnehmung 16 aus. Heckseitig weist die Sprengladung 70 eine Bohrung 74 auf. Die Stirnfläche 72 liegt in einem Abstand 76 zum Ende 36 des Splittermantels 24.An explosive charge 70 fills the recess 16. The explosive charge on the rear side 70 a bore 74. The end face 72 lies at a distance 76 from End 36 of the splinter jacket 24.

Das dargestellte Ausführungsbeispiel stellt die eingangs erwähnte dritte Alternative dar, nämlich ein ballistisches Splittergeschoß 1 mit wesentlich vergrößertem Sprengstoffanteil 70 bei Beibehaltung der üblichen Dicken von Geschoßspitze (Durchschlagskern 12) und Wandung des Splittermantels 24.The illustrated embodiment represents the third alternative mentioned at the beginning represents, namely a ballistic fragmentary floor 1 with a substantially enlarged Explosives content 70 while maintaining the usual thicknesses of the tip of the projectile (Penetration core 12) and wall of the splinter jacket 24.

Die Penetrationsleistung des Durchschlagkernes 12 ist bei Flugzeugstrukturen und leicht gepanzerten Fahrzeugen aufgrund der überlangen Sprengladung 70 gegeben. Der auf den Durchschlagskern 12 übertragene Sprengladungs-Impuls ist wesentlich höher als beim Stand der Technik. Auch die Splitterleistung ist ebenfalls wesentlich höher. Die Sprengstoffbelegung ist in Bezug auf den Splittermantel 24 wesentlich höher als beim Stand der Technik.The penetration performance of the puncture core 12 is in aircraft structures and given armored vehicles due to the overly long explosive charge 70. The explosive charge pulse transmitted to the breakdown core 12 is essential higher than in the prior art. The splinter power is also essential higher. The explosive occupancy is significantly higher with respect to the fragment jacket 24 than in the prior art.

Durch die bodenseitige Zündung erhalten die Splitter eine größere Geschwindigkeit als durch eine etwa mittige Zündung der Sprengladung 70. Diese Geschwindigkeit resultiert aus der Addition von Geschoßgeschwindigkeit und sprengstoffseitiger Splittergeschwindigkeit. Die bodenseitige Zündung ist also von zweifachem Vorteil.The splinters get a higher speed due to the ignition at the bottom than by an approximately central ignition of the explosive charge 70. This speed results from the addition of the bullet speed and the explosive side Splinter speed. The ignition on the bottom is therefore double Advantage.
