BESCHREIBUNG  DESCRIPTION
Wurfkörper projectile
Die Erfindung betrifft einen Wurfkörper mit einem Hülsenboden sowie der Einstellmöglichkeit verschiedener Reichweiten für diesen Wurfkörper. The invention relates to a projectile with a sleeve bottom and the setting of different ranges for this projectile.
Aus bekannten Werfern verschießbare Spreng-, Nebel-, Leucht- oder Übungsmunition enthalten in der Regel eine fest vorgegebene Menge an Treibladungspulver (Ausstoßladung), sodass die Wurfkörper des gleichen Typs nach Zündung der Ausstoßladung im Wesentlichen alle die gleiche Beschleunigung erhalten und damit, bei vorgegebenem Richtwinkel, auch etwa gleich weit geworfen werden. From known throwers shootable explosive, fog, light or practice ammunition usually contain a fixed amount of propellant charge powder (ejection charge), so that the projectile of the same type after ignition of the ejection charge receive substantially all the same acceleration and thus, for a given Straightening angle, even about the same throw.
Einen Werfer dieser Art beschreibt beispielsweise die DE 20 2005 020 752 U1 , eine entsprechende Munition die DE 693 11 805 T2. Aus der DE 10 2006 004 954 A ist ein Munitionsmagazin und eine damit ausgebildete Selbstschutzanlage bekannt. Mit der Elektronik für eine Wirkmittelwurfanlage beschäftigt sich die DE 10 2006 004 992 A. Einen pyrotechnischen Wirkkörper zur Scheinzielerzeugung offenbart des Weiteren die DE 10 2004 047 231 B. A launcher of this type describes, for example, DE 20 2005 020 752 U1, a corresponding ammunition DE 693 11 805 T2. From DE 10 2006 004 954 A an ammunition magazine and a self-protection system formed therewith are known. DE 10 2006 004 992 A deals with the electronics for an active substance throwing system. DE 10 2004 047 231 B further discloses a pyrotechnic active body for generating dummy targets.
Der Erfindung liegt die Aufgabe zugrunde, einen Wurfkörper aufzuzeigen, der mehr als eine festgelegte Reichweite erreichen kann. The invention has for its object to show a throwing body that can reach more than a specified range.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche. This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
Die Erfindung beruht im Wesentlichen auf dem Gedanken, im Hülsenboden des einen Wirkkörper umfassenden Wurfkörpers (Munition) mindestens zwei voneinander getrennte Kammern anzuordnen, in denen sich jeweils eine mittels eines elektrischen Anzünders anzündbare Treibladung befindet, wobei die beiden Anzünder mit einer im Hülsenboden befindlichen Steuereinrichtung elektrisch verbunden sind, die von einer außerhalb der Munition befindlichen Abschußvorrichtung betätigbar ist, derart, dass alternativ nur ein oder beide Anzünder aktiviert werden. Dadurch kann bei unterschiedlicher Wahl der Treibladungsmengen in den beiden Kammern des Hülsenbodens der Wirkkörper mit drei unterschiedlichen Beschleunigungen verschossen werden. The invention is based essentially on the idea of at least two separate from one another in the case bottom of the projectile body (ammunition) comprising one active body To arrange chambers in each of which is a flammable by means of an electric igniter propellant charge, the two lighters are electrically connected to a control device located in the bottom of the case, which is actuated by a launcher located outside of the ammunition, such that alternatively only one or both lighters to be activated. As a result, with different choice of propellant charge quantities in the two chambers of the sleeve bottom of the active body can be fired with three different accelerations.
Vorzugsweise kann der Hülsenboden drei voneinander getrennt angeordnete Kammern umfassen, sodass mittels der Steuereinrichtung alternativ nur eine, zwei oder alle drei Anzünder aktivierbar sind. Alternative Anzahlen von Kammern sind frei wählbar. The sleeve base may preferably comprise three chambers arranged separately from one another, so that by means of the control device, alternatively, only one, two or all three igniters can be activated. Alternative numbers of chambers are freely selectable.
Zur elektrischen Verbindung der Steuereinrichtung mit der externen Abschußvorrichtung können an dem äußeren Umfang des Hülsenbodens Kontaktringe vorgesehen sein, welche mit der Steuereinrichtung elektrisch verbunden sind. For electrical connection of the control device with the external launcher contact rings may be provided on the outer periphery of the sleeve bottom, which are electrically connected to the control device.
Durch diese Konstruktion einer integrierten variablen Ausstoßladung ist es möglich, dem Wurfkörper bzw. Wirkkörper noch direkt vor dem Verschießen die maximal erreichbare Beschleunigung (und damit auch die maximal erreichbare Entfernung) ohne Richtwinkeländerung aufzuprägen und gegebenenfalls auch zu verändern. By this construction of an integrated variable discharge charge, it is possible to impose the maximum speed achievable (and thus also the maximum achievable distance) without straightening angle change the throwing body or active body directly before the shooting and possibly also to change.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus dem folgenden, anhand einer Figur erläuterten Ausführungsbeispiel. Further details and advantages of the invention will become apparent from the following, explained with reference to a figure embodiment.
In der Figur ist schematisch der heckseitige Bereich eines aus einem Werfer verschießbaren Wurfkörpers (beispielsweise einer Splittergranate) im Längsschnitt dargestellt. Der mit 1 bezeichnete Wurfkörper umfasst einen Hülsenboden 2 mit einem darin angeordneten Wirkkörper 3. In the figure, the rear-side region of a projectile from a launcher throwing body (for example, a fragmentation grenade) is shown schematically in longitudinal section. The projecting body designated 1 comprises a sleeve base 2 with a body 3 arranged therein.
Erfindungsgemäß sind in dem Hülsenboden 2 heckseitig wenigsten zwei, hier bevorzugt drei, voneinander getrennt angeordnete Kammern 4-6 vorgesehen. In diesen Kammern 4- 6 befinden sich mittels elektrischer Anzünder 7-9 anzündbare Treibladungen 10-12. According to the invention, at least two, preferably three, separate chambers 4-6 are provided in the bottom of the sleeve 2 at the rear. In these chambers 4-6 are by means of electric lighters 7-9 ignitable propellant charges 10-12.
Die Anzünder 7-9 sind über elektrische Leitungen 13-15 mit einer im Hülsenboden 2 befindlichen Steuereinrichtung 16 verbunden, die ihrerseits mit außenseitig an dem Hülsen- boden 2 angeordneten Kontaktringen 17, 18 verbunden ist. Über diese Kontaktringe 17, 18 kann die Steuereinrichtung 16 von einer Abschussvorrichtung (nicht näher dargestellt) betätigt werden, derart, dass alternativ nur ein, zwei oder alle drei Anzünder 7-9 aktiviert werden. The lighters 7-9 are connected via electrical lines 13-15 with a located in the sleeve bottom 2 control device 16, which in turn connected to the outside of the sleeve floor 2 arranged contact rings 17, 18 is connected. By means of these contact rings 17, 18, the control device 16 can be actuated by a launcher (not shown in more detail), such that alternatively only one, two or all three lighters 7-9 are activated.
Beispielsweise kann vorgesehen sein, dass der Wirkkörper 3 bei Zündung der Treibladung 10 eine Reichweite von ca. 40 m, bei Zündung der Treibladungen 10 und 11 eine Reichweite von 75 m und bei Zündungen der Treibladungen 10, 1 1 und 12 eine Reichweite von 100 m besitzt. Bei Integration anderer verschiedener Ladungen kann der Wirkkörper 3 aber auch eine erste Reichweite von 40 m, eine zweite von 50 m und eine dritte von 80 m erreichen. For example, it can be provided that the active body 3 at ignition of the propellant charge 10, a range of about 40 m, upon ignition of the propellant charges 10 and 11, a range of 75 m and ignitions of the propellant charges 10, 1 1 and 12, a range of 100 m has. When integrating other different charges, however, the active body 3 can also reach a first range of 40 m, a second range of 50 m and a third of 80 m.
