Definitions
- 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 projectile.
- EP 0 365 886 A1 and GB 11 77 813 disclose a fragmentary projectile with a base igniter that can be connected to a propellant charge sleeve.
- the length of the base igniter, which lies in the splinter jacket, corresponds approximately to the length of the explosive charge within the splinter jacket.
- an explosive charge and a detonator are arranged in a rear-side recess.
- the detonator is short and is based on the principle of a revolver cartridge, which is no longer permitted due to the safety regulations. Because of the short construction detonator, the length of the explosive in relation to the detonator is very long.
- the length of the base igniter within the splinter jacket is approximately 60% with respect to the length of the explosive.
- a short base igniter is provided, which for the most part lies within the splinter jacket.
- the invention has for its object to provide a fragmentary projectile with propellant charge sleeve, which has an improved effect in the target.
- the inventive design of the fragmentation projectile with a projectile detonator extended beyond the rear end of the fragmentation jacket results in three different possibilities for optimizing the projectile performance, and bar improvement in the penetration performance by increasing the mass of the projectile head, optimizing the effective fragmentation by increasing the wall thickness of the fragmentation sleeve while maintaining the usual explosive content or increase in the explosive content while maintaining the usual thicknesses of the projectile tip and wall of the fragment shell.
- FIG. 1 An embodiment of the invention is shown in the drawing.
- the single figure shows a longitudinal section through a cartridge ammunition.
- a fragmentary bullet 1 with a caliber of 30 mm has a base igniter 2, a guide band 3 and is connected to a propellant charge sleeve 4.
- Part of a storey log 10 is designed as a solid breakdown core 12.
- a recess 16 with a length 18 adjoins the punch core 12 with a length 14 at the rear.
- the recess 16 is divided into a conical and a cylindrical section 20, 22. These sections 20, 22 represent the fragment jacket 24.
- a groove 26 is provided for the strangled propellant charge sleeve 4 and a threaded connection 5 for the base igniter 2.
- the front end of the propellant charge sleeve 4 is designated 30 and is at a distance 31 from the rear end 36 of the splinter jacket 24 or the plane 34. This distance 31 is slightly less than 1/3 of the caliber 32.
- the ground igniter 2 has an overall length 50 with two approximately equal partial lengths, namely an inner partial length 52 and an outer partial length 54.
- the ground igniter 2 also has a cylindrical section 56 with a damping body 57, a peg-shaped housing 60 for a booster charge, not shown, corresponding to the partial length 52 and a conical stop collar 62 with a rear-side, conical pin 64 corresponding to the outer partial length 54.
- the stop collar 62 and the pin 64 lie within the propellant charge sleeve 4 with the cargo 66 poured into the cargo space 68, that is to say outside of the fragment jacket 24.
- the cargo 66 completely fills the cargo space 68.
- An explosive charge 70 fills the recess 16.
- the explosive charge 70 has a bore 74 on the rear side.
- the end face 72 lies at a distance 76 from the end 36 of the splinter jacket 24.
- the illustrated embodiment represents the third alternative mentioned at the outset, namely a ballistic fragmentary projectile 1 with a substantially enlarged one Explosive component 70 while maintaining the usual thicknesses of the projectile tip (penetration core 12) and wall of the splinter jacket 24.
- the penetration performance of the puncture core 12 is given in aircraft structures and lightly armored vehicles due to the excessively long explosive charge 70.
- the explosive charge pulse transmitted to the breakdown core 12 is significantly higher than in the prior art.
- the fragmentation performance is also much higher.
- the explosive occupancy with respect to the fragment jacket 24 is significantly higher than in the prior art.
- the splinters are given a higher speed by the ignition at the bottom than by an approximately central detonation of the explosive charge 70. This speed results from the addition of the projectile speed and the explosive-side splinter speed.
- the ignition on the bottom is therefore of two advantages.

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 projectile.
Aus der EP 0 365 886 A1 und der GB 11 77 813 ist ein Splittergeschoß mit Bodenzünder bekannt, das mit einer Treibladungshülse verbindbar ist. Die Länge des Bodenzünders, die im Splittermantel liegt, entspricht etwa der Länge der Sprengladung innerhalb des Splittermantels.EP 0 365 886 A1 and GB 11 77 813 disclose a fragmentary projectile with a base igniter that can be connected to a propellant charge sleeve. The length of the base igniter, which lies in the splinter jacket, corresponds approximately to the length of the explosive charge within the splinter jacket.
Bei einem flügelstabilisierten Artilleriegeschoß nach der DE-PS 89 235 sind in einer heckseitigen Ausnehmung eine Sprengladung und ein Boderzünder 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 Boderzünders ist die Länge des Sprengstoffes in bezug auf den Zünder sehr groß.In a wing-stabilized artillery projectile according to DE-PS 89 235, an explosive charge and a detonator are arranged in a rear-side recess. The detonator is short and is based on the principle of a revolver cartridge, which is no longer permitted due to the safety regulations. Because of the short construction detonator, the length of the explosive in relation to the detonator is very long.
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 within the splinter jacket is approximately 60% with respect to the length of the explosive.
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, a short base igniter is provided, which for the most part lies within the splinter jacket.
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 detonator requires only a fraction of the length of the fragmentation shell provided for the explosive charge. The main part of the detonator is outside the splinter jacket. In artillery shells, the propellant charge is known to be separate from the artillery shell, i.e. the charges are fed to the gun separately from the artillery shell. A propellant charge case is therefore not used. This means that there is enough space for a detonator in the gun in the rear area of the projectile, depending on the circumstances.
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, that is to say bullets with propellant charge sleeves arranged thereon, only a small volume is available for the detonator due to the circumstances of the propellant charge sleeve.
Der Erfindung liegt die Aufgabe zugrunde, ein Splittergeschoß mit Treibladungshülse zu schaffen, das eine verbesserte Wirkung im Ziel aufweist.The invention has for its object to provide a fragmentary projectile with propellant charge sleeve, which has an improved effect in the target.
Diese Aufgabe wird entsprechend den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in accordance with the characterizing features of claim 1.
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 bar 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.The inventive design of the fragmentation projectile with a projectile detonator extended beyond the rear end of the fragmentation jacket results in three different possibilities for optimizing the projectile performance, and bar improvement in the penetration performance by increasing the mass of the projectile head, optimizing the effective fragmentation by increasing the wall thickness of the fragmentation sleeve while maintaining the usual explosive content or increase in the explosive content while maintaining the usual thicknesses of the projectile tip and wall of the fragment shell.

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
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
Der Bodenzünder 2 besitzt eine Gesamtlänge 50 mit zwei etwa gleichgroßen Teillängen, nämlich einer inneren Teillänge 52 und einer äußeren Teillänge 54.The
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
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
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
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 outset, namely a ballistic fragmentary projectile 1 with a substantially enlarged one
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
The explosive occupancy with respect to the
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 are given a higher speed by the ignition at the bottom than by an approximately central detonation of the
