Description

Die Erfindung betrifft ein Übungsgeschoß mit einer Geschoßhülle und einem Aufschlagzünder.The invention relates to a training projectile with a projectile casing and an impact detonator.

Ein gattungsgemäßes Übungsgeschoß, insbesondere für Artilleriewaffen, ist aus der DE 35 31 688 A1 bekannt. Bei diesem bekannten Übungsgeschoß wird beim Zielaufschlag der Boden des Geschosses mittels einer Hohlladung abgesprengt, so daß aus der entsprechenden bodenseitigen Öffnung zur besseren Sichtbarmachung des Auftreffpunktes mittels einer Deutladung erzeugter Rauch austritt.A generic projectile, especially for artillery weapons, is known from DE 35 31 688 A1. With this Known practice floor is the bottom of the Projectile blasted off with a shaped charge, so that from the corresponding opening on the bottom for better visibility of the point of impact generated by a German charge Smoke escapes.

Nachteilig ist bei diesem bekannten Übungsgeschoß unter anderem, daß die Herstellkosten aufgrund der verwendeten Hohlladung relativ hoch sind, und daß sie bei Aktivierung der Hohlladung eine gegenüber vergleichbaren scharfen Sprenggeschossen zu starke Blitzwirkung besitzen. Außerdem ist die Entsorgung der Munitionsteile sehr kostenintensiv.A disadvantage of this known practice floor is, among other things, that the manufacturing costs due to the shaped charge used are relatively high, and that when the shaped charge is activated one compared to comparable sharp explosive projectiles have too much lightning. In addition, the disposal of the ammunition parts very expensive.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Übungsgeschoß, insbesondere für Artilleriewaffen, anzugeben, welches im Vergleich zu bekannten Übungsgeschossen kostengünstiger fertigbar ist, bei seinem Auftreffen im Ziel nur zu einer geringen Lärmbelästigung führt und außerdem bei seiner Detonation eine gute Signatur aufweist.The present invention is based on the object To indicate the practice floor, especially for artillery weapons, which is cheaper compared to known practice projectiles is producible, when it hits the finish only to low noise pollution and also with its Detonation has a good signature.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is solved by the features of claim 1. Disclose further advantageous refinements of the invention the subclaims.

Im wesentlichen liegt der Erfindung der Gedanke zugrunde, in dem Übungsgeschoß mittig ein von einer Inertmasse umgebenes Rohr aus Kunststoff oder Metall anzuordnen, welches abschnittsweise mit Sprengstoff (Wirkladungen) gefüllt ist, wobei die einzelnen Wirkladungen durch Übertragungsladungen miteinander verbunden sind.Basically, the invention is based on the idea of the center of the practice floor is surrounded by an inert mass Pipe made of plastic or metal, which in sections is filled with explosives (active charges), where the individual active charges by transfer charges are interconnected.

Das erfindungsgemäße Übungsgeschoß weist eine Reihe von Vorteilen auf:The practice floor according to the invention has a number of Advantages on:

Durch die Beabstandung der Wirkladungen wird erreicht, daß relativ große Splitter bei der Aktivierung der Wirkladungen erzeugt werden, die nach der Detonation des Übungsgeschosses im Zielgebiet auf einfache Weise entsorgt werden können, zumal durch den bei der Detonation entstehende Druck das Inertmaterial vollständig von der Geschoßhülle gelöst wird, wobei die Inertmasse toxikologisch unbedenklich ist und im Zielgebiet verbleiben kann.The spacing of the active charges ensures that relatively large splinters when activating the active charges generated after the detonation of the practice floor can be disposed of easily in the target area, especially since the inert material due to the pressure generated during the detonation is completely detached from the shell, whereby the inert mass is toxicologically safe and in the target area can remain.

Anders als im Falle der DE 35 31 688 A1 entstehen keine gefährlichen nach hinten wegfliegenden Splitter, d.h., es ist nur ein geringer Sicherheitsbereich erforderlich.Unlike in the case of DE 35 31 688 A1, there are no dangerous ones fragments flying backwards, i.e. it is only a small security area required.

Der Detonationsknall ist aufgrund der geringen Sprengstoffmenge gegenüber scharfen Geschossen stark reduziert. The detonation bang is due to the small amount of explosives greatly reduced compared to live projectiles.

Die Deutwirkung (Blitz und Rauch) derartiger Übungsgeschosse ist im wesentlichen vergleichbar mit entsprechenden scharfen Geschossen.The meaningful effect (lightning and smoke) of such practice projectiles is essentially comparable to corresponding sharp ones Shot.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus dem folgenden anhand einer Figur erläuterten Ausführungsbeispiel.Further details and advantages of the invention emerge from the following exemplary embodiment explained with reference to a figure.

In der Fig. wird der Längsschnitt eines Artillerie-Übungsgeschosses dargestellt, welches mit dem Bezugszeichen 1 versehen ist. Das Übungsgeschoß 1 umfaßt eine Geschoßhülle 2 aus Stahl und einen vorderseitig in die Hülle 2 eingeschraubten Hebestopfen 3, der zum Verschuß gegen einen als Kopfzünder ausgebildeten Aufschlagzünder (nicht dargestellt) ausgetauscht wird. In der Geschoßhülle 2 ist ein Körper 5 aus einer z.B. toxikologisch unbedenklichen Inertmasse angeordnet, der einen zentralaxialen Kanal 6 aufweist. In diesem Kanal befindet sich ein relativ dünnwandiges Metalloder Kunststoffrohr 7.The figure shows the longitudinal section of an artillery training projectile shown, which is provided with the reference number 1 is. The practice floor 1 comprises a shell 2 Steel and one screwed into the casing 2 on the front Lifting plug 3, which is used to fire a head detonator trained impact detonators (not shown) is exchanged. In the shell 2 a body 5 is made one e.g. toxicologically harmless inert mass arranged, which has a central axial channel 6. In this channel is a relatively thin-walled metal or Plastic pipe 7.

Erfindungsgemäß sind in dem Rohr 7 abschnittsweise Sprengstoffbereiche (Wirkladungen) 8-11 vorgesehen, die mittels Übertragungsladungen 12 miteinander verbunden sind. Die Übertragungsladungen 12 sind innerhalb von z.B. aus Kunststoff bestehenden Inertkörpern 13, die gleichzeitig den Abstand der Wirkladungen 8-11 voneinander definieren, angeordnet.According to the invention, there are sections of explosives in the pipe 7 (Active charges) 8-11 provided by means of Transfer charges 12 are interconnected. The Transfer charges 12 are within e.g. made of plastic existing inert bodies 13, which at the same time Define the distance between the active charges 8-11, arranged.

Die Anzahl und Stärke der Wirkladungen 8-11 ist so gewählt, daß die Zerlegung der Hülle 2 in der gewünschten Weise (relativ große Splitter) erfolgt und die von einem Beobachter gesehene Signatur des detonierenden Übungsgeschosses 1 die vorgegebene Form aufweist.The number and strength of the active charges 8-11 is chosen so that the disassembly of the shell 2 in the desired manner (relatively large splinters) and that from an observer seen signature of the detonating practice floor 1 die has a predetermined shape.

Um eine sichere Anfeuerung der aus den Wirk- und Übertragungsladungen bestehenden Sprengstoffsäule zu erreichen, hat es sich als vorteilhaft erwiesen, wenn die dem Aufschlagzünder benachbarte Wirkladung 11 und die Übertragungsladungen 12 aus einem überwiegend aus Hexogen- oder Oktogen-haltigen Sprengstoff bestehen. Die weiteren Wirkladungen 8-10 können dagegen aus Trinitrotoluol (TNT) oder Composition B (Comp B) bestehen.In order to safely fire up the active and To reach transfer charges existing explosive column it has proven to be advantageous if the Impact detonator adjacent active charge 11 and the transfer charges 12 from a predominantly from hexogen or Explosives containing octogen exist. The further real charges In contrast, 8-10 can be made from trinitrotoluene (TNT) or Composition B (Comp B) exist.

Als vorteilhaft hat es sich ferner erwiesen, wenn in dem Bereich zwischen dem Geschoßboden 14 des Übungsgeschosses 1 und der dem Geschoßboden nächsten Wirkladung 8 eine die Signatur verbessernde Deutladung 15 angeordnet ist, die aus einer geeigneten pyrotechnischen Masse zur Verbesserung von Rauch und/oder Blitz besteht. Die Deutladung 15 kann aber auch aus einer schüttfähigen Inertmasse (z.B. Flammruß) lediglich zur Verbesserung der Rauchwirkung bestehen.It has also proven to be advantageous if in the Area between the floor 14 of the practice floor 1 and the active charge 8 closest to the floor of the storey Signature-enhancing Deut Charge 15 is arranged that from a suitable pyrotechnic mass to improve There is smoke and / or lightning. The Deut Charge 15 can also from a pourable inert mass (e.g. flame soot) exist only to improve the smoke effect.

Die Erfindung ist selbstverständlich nicht auf das konkret dargestellte Ausführungsbeispiel beschränkt. So können beispielsweise die Wirk- und Übertragungsladungen auch direkt in dem in der Fig. mit 6 bezeichneten zentralaxialen Kanal der Inertmasse 5 angeordnet werden. Die Verwendung eines separaten Rohres weist den großen Vorteil auf, daß die gesamte aus Wirk-, Deut- und Übertragungsladungen bestehende Sprengstoffsäule als vorgefertigte Einheit hergestellt und nach Entfernung des Hebestopfens 3 durch die vorderseitige Öffnung der Geschoßhülle 2 in diese eingebracht werden kann. Die Inertmasse 5 wird entweder vor dem Einsetzen des Rohres bzw. der vorgefertigten Einheit oder anschließend in Form eines entsprechenden schüttfähigen oder gießfähigen Materials in die Geschoßhülle gefüllt. The invention is of course not specific to this illustrated embodiment limited. For example the active and transfer charges also directly in the 6 designated central axial channel of the Inert mass 5 can be arranged. The use of a separate tube has the great advantage that the total consisting of real, German and transmission charges Explosives column manufactured as a prefabricated unit and after removing the lifting plug 3 by the front Opening of the shell 2 can be introduced into this. The inert mass 5 is either before the tube is inserted or the prefabricated unit or subsequently in the form a suitable pourable or pourable material filled in the shell.
