Description

Subprojektil mit energetischem Inhalt Sub-projectile with energetic content
Die Erfindung betrifft insbesondere rotationsstabilisierte Subprojektile eines Geschosses, welche einen energetischen Inhalt umfassen.The invention relates in particular to rotationally stabilized subprojectiles of a projectile, which comprise an energetic content.
Es ist bekannt, Brandmassen als Splitter-Brandmunition in einem Geschosskörper oder Sprengkopf zusammen mit einem brisanten Sprengstoff als auch in panzerbrechenden Geschossen, die keinen Sprengstoff enthalten, einzubinden. Durch die detonative oder mechanische Fragmentierung des Geschosses oder Sprengkopfes im oder nahe des Zieles entstehen neben den Splittern schnell fliegende, in der Luft autonom brennende Brandmasse- Teilchen. Erzielt wird dabei eine räumliche und zeitlich stark ausgedehnte Brandwirkung.It is known to incorporate fire masses as splinter fire ammunition in a projectile body or warhead together with a explosive explosive as well as in armor-piercing projectiles containing no explosives. Due to the detonative or mechanical fragmentation of the projectile or warhead in or near the target, apart from the splinters, fast-flying, autonomously burning particles of fire mass are formed. This results in a spatially and temporally strong fire effect.
Bekannte Splitter-Brandmunitionen enthalten Mischungen aus hochbrisanten Sprengstoffen wie Hexogen, Oktogen, Trotyl und Aluminiumpulver.Known splinter firing munitions contain mixtures of highly explosive explosives such as hexogen, octogen, trotyl and aluminum powder.
Die DE 29 01 517 beschreibt eine Brandmasse mit einem organischen Bindemittel und einem Metallschwamm, z.B. aus Zirkon oder Hafnium, wobei als Bindemittel Polytetrafluor- ethylen mit einem Anteil von 2- bis 15-Masse-% verwendet wird.DE 29 01 517 describes a fire mass with an organic binder and a metal sponge, e.g. zirconium or hafnium, polytetrafluoroethylene being used as binder at a level of from 2 to 15% by mass.
Mit der firmeneigenen EP 0 051 324 B1 wird eine gattungsgemäße Brandmasse offenbart, die ein organisches Bindemittel und Metallteilchen verwendet. Um eine Verlängerung der Brennzeit zu erreichen, schlägt diese Lösung vor, Metallpulver mit einer mittleren Korngröße von 15-50 μm zu verwenden. Das Bindemittel, ein organischer halogenfreier Binder, ein Po- lyvinylacetat, weist einen Anteil kleiner als 2-Masse-% auf. Damit wird noch eine ausreichende Verpressbarkeit des Metallpulvers gewährleistet. Der Metallzusatz selbst bewirkt eine Steigerung der Blastwirkung und eine Verlängerung der Flammen-Standzeit von 1 ms auf 15ms. Dies erhöht die Anzündwahrscheinlichkeit für brennbares Material.The company's EP 0 051 324 B1 discloses a generic fire mass which uses an organic binder and metal particles. In order to achieve an extension of the firing time, this solution proposes to use metal powder with an average grain size of 15-50 μm. The binder, an organic halogen-free binder, a polyvinyl acetate, has a content of less than 2% by mass. This still ensures sufficient compressibility of the metal powder. The metal additive itself causes an increase in blast effect and an extension of the flame life from 1 ms to 15 ms. This increases the ignition probability for combustible material.
Auf diese Brandmasse aufbauend wird mit der weiteren DE 10 2005 057 182 A1 vorgeschlagen, vorzugsweise kugelförmiges Metallpulver im Bereich von 50-250μm zu verwenden. Damit kann der Binder in der kleinstmöglichen Konzentration eingesetzt werden, die noch eine ausreichende Verpressbarkeit und Fixierung der Brandmasse gewährleistet. Die Nutzung kugelförmiger Metallpulver, insbesondere von Zirkon-Metallpulver, mit höherer Oberfläche ermöglicht, dass der Binder trocken auf die Oberfläche des Metallpulvers appliziert werden kann, wodurch die Rieselfähigkeit erhöht und ein volumetrisches Dosieren möglich ist.Building on this fire mass is proposed with the further DE 10 2005 057 182 A1, preferably to use spherical metal powder in the range of 50-250μm. Thus, the binder can be used in the smallest possible concentration, which still ensures sufficient compressibility and fixation of the fire mass. The use of spherical metal powders, in particular zirconium metal powders, with a higher surface area allows the binder to be applied dry to the surface of the metal powder, which increases the flowability and allows volumetric metering.
Mit der EP 1 286 129 A1 wird ein weiterer Brandsatz für ein flügelstabilisiertes Wuchtge- schoss publiziert, der trotz eines relativ geringen Volumens und einer geringen Masse eine gute Wirkung besitzt. Gezündet wird der Brandsatz durch die beim Aufprall auf ein Ziel entstehenden Schockwellen. Verwendet wird ein Titanschwamm und als Bindemittel ein Epoxid- oder Polyesterharz. Der Korngrößenbereich des Titanschwammes liegt dabei um 450μm, wobei 30% eine Korngröße größer und 70% kleiner 450μm aufweisen.EP 1 286 129 A1 discloses another fire rate for a wing-stabilized balancing bullet, which has a good effect despite a relatively small volume and a low mass. The fire rate is ignited by the shock waves that occur when impacting a target. A titanium sponge is used and as binder an epoxy or polyester resin. The particle size range of the titanium sponge is 450 μm, with 30% having a particle size greater and 70% less than 450 μm.
Die Erfindung stellt sich die Aufgabe, eine insbesondere im Ziel effektivere Brandwirkung zu erreichen bzw. mit energetischem Zielmaterial in Reaktion zu treten.The object of the invention is to achieve a fire effect that is more effective, especially in the target, or to react with energetic target material.
Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.The problem is solved by the features of claim 1. Advantageous embodiments are listed in the subclaims.
Der Erfindung liegt die Idee zugrunde, die Brandmasse bzw. die energetische Komponente eines Geschosses in die Subprojektile einzubinden. Ähnlich wie bei der DE 10 2005 039 901 A1 werden die Subprojektile aus duktilem Schwermetall oder Hartmetall in bekannter Art und Weise in einer Zylinder, Kugel- oder Würfelform mit einer Aussparung mit oder ohne Sollbruchstellen hergestellt. Danach erfolgt das Einbringen und Verdichten, vorzugsweise maschinell, der energetischen Komponente sowie, falls vorgesehen, der Zudosierung einer druckempfindlichen Anzündladung mit anschließender Verpressung.The invention is based on the idea of incorporating the fire mass or the energetic component of a projectile into the subprojectiles. Similar to DE 10 2005 039 901 A1, the subprojectiles are made of ductile heavy metal or hard metal in a known manner in a cylinder, ball or cube shape with a recess with or without predetermined breaking points. Thereafter, the introduction and compression takes place, preferably by machine, the energetic component and, if provided, the metered addition of a pressure-sensitive ignition charge with subsequent pressing.
Die Freisetzung der Subprojektile kann in bekannter Art und Weise erfolgen.The release of subprojectiles can be done in a known manner.
Die Aktivierung des energetischen Inhalts des Subprojektils erfolgt je nach Auslegung durch:The energetic content of the sub-projectile is activated by:
- Anzündung im Trägergeschoss zusammen mit der Zerlegerladung (Ausstoßladung),- Ignition in the carrier level together with the Zerlegerladung (ejection charge),

Für die Anfeuer-Pyrotechnik werden Mg, Al1 Si - Bariumperoxid- Systeme eingesetzt, wie beispielsweise das firmeneigene YIS 506.- Ignition when hitting the finish. The energetic content of the subprojectiles includes a pyrotechnic, such as Thermite, Pyrofuze (see http://www.sigmundcohn.com/german/pyrofuse.html, DE 21 30 367 A1) or Coruscative (US 3,135,205) with thermobaric reactions. For the kindling pyrotechnics Mg, Al 1 Si - Bariumperoxid- systems are used, such as the company's own YIS 506.
Die Subprojektile sind vorzugsweise rotationsstabilisiert. Durch die Rotationsstabilisierung wird ein orientiertes Auftreffen des / der Subprojektile im Ziel ermöglicht. (Die Rotation beträgt ca. 1 000 Hz an der Rohrmündung).The subprojectiles are preferably rotationally stabilized. The rotation stabilization allows an oriented impact of the sub-projectile (s) in the target. (The rotation is about 1000 Hz at the mouth of the pipe).
Die Orientierung - Kavität mit energetischem Inhalt kann front- oder heckseitig im Subprojek- til erfolgen.The orientation - cavity with energetic content can be done on the front or rear side in the subprojectile.
