Description

Die Erfindung betrifft eine Manöverpatrone nach dem Oberbegriff des Anspruchs 1.The invention relates to a maneuvering cartridge according to the preamble of claim 1.

Aus der DE 41 28 050 A1 ist eine derartige Manöverpatrone bekannt, deren Berstkörper als Geschoßnachbildung ausgebildet ist und an beiden Enden einen Bund mit etwas vergrößertem Durchmesser aufweist, wobei der vordere, mit einer Schräge versehene Bund dazu dient, mit einer Auflaufschräge eines entsprechenden, im Manöver zu verwendenden Rohreinsatzes für das Gefechtsrohr beim Einschieben der Manöverpatrone in dieses in Eingriff zu gelangen, wodurch der Berstkörper in die Treibladungshülse geschoben wird. Der hintere Bund wird von dem Mundstück aufgenommen und ist mit diesem beispielsweise verklebt oder verwürgt. Nach dem Verschießen wird die Treibladungshülse zusammen mit dem größtenteils darin befindlichen Berstkörper ausgeworfen. Wird diese Manöverpatrone jedoch vorschriftswidrig ohne den für Manöverzwecke vorgesehenen Rohreinsatz verschossen, kann der Berstkörper die Treibladungshülse verlassen und stellt insofern ein erhebliches Gefährdungspotential dar.Such a maneuvering cartridge is known from DE 41 28 050 A1, the bursting body of which is designed as a projectile replica and has a collar with a somewhat enlarged diameter at both ends, the front collar, which is provided with a bevel, being used with a run-up slope of a corresponding im Pipe insert to be used for the battle tube when the maneuver cartridge is inserted into it, whereby the bursting body is pushed into the propellant charge sleeve. The rear collar is picked up by the mouthpiece and is glued or choked to it, for example. After firing, the propellant charge shell is ejected together with the bursting body that is largely located therein. However, if this maneuver cartridge is fired in violation of the regulations without the pipe insert intended for maneuvering purposes, the bursting body can leave the propellant charge shell and thus represents a considerable risk potential.

Aufgabe der Erfindung ist es, eine Manöverpatrone nach dem Oberbegriff des Anspruchs 1 zu schaffen, die dann, wenn sie aus einem normalen Gefechtsrohr abgeschossen wird, kein Gefährdungspotential darstellt.The object of the invention is to provide a maneuvering cartridge according to the preamble of claim 1 which, when fired from a normal battle tube, does not represent a hazard potential.

Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved in accordance with the characterizing part of claim 1.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further refinements of the invention can be found in the following description and the subclaims.

Die Erfindung wird nachstehend anhand eines in den beigefügten Abbildungen dargestellten Ausführungsbeispiels näher erläutert.The invention is explained below with reference to an embodiment shown in the accompanying figures.

Fig. 1 bis 4 zeigen ausschnittweise und im Schnitt aufeinander folgende Schritte beim Montieren eines Berstkörpers und einer Treibladungshülse zu einer Manöverpatrone.1 to 4 show sections and successive steps in assembling a bursting body and a propellant charge sleeve to form a maneuvering cartridge.

Die Manöverpatrone umfaßt, wie sich aus Fig. 4 ergibt, eine Treibladungshülse 1, die ein Mundstück 2 und eine schräge Schulter 3 zur Anlage an einer entsprechenden Schulter eines Patronenlagers eines Waffenrohrs besitzt.The maneuver cartridge comprises, as can be seen from FIG. 4, a propellant charge sleeve 1 which has a mouthpiece 2 and an oblique shoulder 3 for abutment on a corresponding shoulder of a cartridge chamber of a weapon barrel.

Die Treibladungshülse 1 nimmt einen Berstkörper 4 im wesentlichen in Form einer Geschoßnachbildung auf. Der Berstkörper 4 umfaßt einen zylindrischen Abschnitt 5, der an beiden Enden jeweils einen Bund 6 mit etwas vergrößertem Durchmesser aufweist. Der heckseitige Bund 6 wird von dem Mundstück 2 aufgenommen und ist mit diesem beispielsweise verklebt oder verwürgt.The propellant charge sleeve 1 receives a burst body 4 essentially in the form of a projectile replica. The bursting body 4 comprises a cylindrical section 5, which has a collar 6 with a somewhat enlarged diameter at both ends. The rear collar 6 is received by the mouthpiece 2 and is glued or choked to it, for example.

Am heckseitigen Bund 6 ist eine umlaufende Nut 7 vorgesehen, die in Axialrichtung gestuft ist, wobei ihr heckseitiger Bereich 8 einen größeren Durchmesser als ihr bugseitiger Bereich 9 aufweist. Die Nut 7 nimmt einen geschlitzten Haltering 10, beispielsweise aus rundem Federstahl auf, dessen Innendurchmesser Spiel zum Durchmesser des heckseitigen Bereichs 8 der Nut 7 aufweist und dessen Außendurchmesser größer als der Außendurchmesser des heckseitigen Bundes 6 ist. Der Durchmesser und die Länge des bugseitigen Bereichs 9 der Nut 7 ist dagegen so groß gewählt, daß er den auf den Außendurchmesser des heckseitigen Bundes 6 zusammengedrückten Haltering aufnehmen kann. Zweckmäßigerweise ist der Haltering 10 etwa doppelt so stark, wie der heckseitige Bereich 8 der Nut 7 tief ist.A circumferential groove 7 is provided on the rear-side collar 6, which is stepped in the axial direction, its rear-side area 8 having a larger diameter than its bow-side area 9. The groove 7 receives a slotted retaining ring 10, for example made of round spring steel, the inside diameter of which has play in relation to the diameter of the rear region 8 of the groove 7 and the outside diameter of which is larger than the outside diameter of the rear collar 6. The diameter and the length of the bow-side region 9 of the groove 7, on the other hand, is chosen so large that it can accommodate the retaining ring compressed on the outer diameter of the rear-side collar 6. The retaining ring 10 is expediently approximately twice as thick as the rear region 8 of the groove 7 is deep.

Auf diese Weise befindet sich bei in das Mundstück 2 eingesetztem Berstkörper 4 der Haltering 10 im heckseitigen Bereich 8 der Nut 7 benachbart zu deren heckseitigem Ende und des weiteren in Eingriff mit der Innenseite der schrägen Schulter 3 der Treibladungshülse 1, so daß der Haltering 10 auch beim Abschießen der Manöverpatrone mittels eines normalen Gefechtsrohrs ohne Manöverrohreinsatz den Berstkörper 4 mit der Treibladungshülse in Eingriff hält, so daß der Berstkörper 4 das Gefechtsrohr nicht verlassen und ein Gefährdungspotential darstellen kann.In this way, when the rupture body 4 is inserted into the mouthpiece 2, the retaining ring 10 is located in the rear region 8 of the groove 7 adjacent to its rear end and furthermore in engagement with the inside of the oblique shoulder 3 of the propellant charge sleeve 1, so that the retaining ring 10 also when the maneuver cartridge is fired by means of a normal battle tube without a maneuver tube insert, the bursting body 4 holds in engagement with the propellant charge sleeve, so that the bursting body 4 cannot leave the battle tube and can represent a potential hazard.

Der heckseitige Bereich 8 der Nut 7 weist mindestens eine dem doppelten Durchmesser des Ringquerschnittes entsprechende axiale Länge auf, so daß der Haltering 10 bei Transport- und Fallbelastungen nicht in den bugseitigen Bereich 9 der Nut 7 gelangen kann, weil beispielsweise bei einem Fallversuch eine geringfügige Verschiebung des Berstkörpers 4 in die Treibladungshülse auftreten kann.The rear area 8 of the groove 7 has at least one axial length corresponding to twice the diameter of the ring cross section, so that the retaining ring 10 cannot reach the bow-side area 9 of the groove 7 during transport and falling loads, for example because of a slight shift in a drop test of the bursting body 4 can occur in the propellant charge sleeve.

Zur Montage wird ein Werkzeug 11 verwendet, das eine Durchtrittsbohrung 12 aufweist, die eine Schulter 13 besitzt, bis zu der das Mundstück 2 in das Werkzeug 11 einführbar ist. Die Durchtrittsbohrung 12 ist oberhalb der Schulter 13 auf einen Durchmesser gleich demjenigen des Bundes 6 bzw. des Innendurchmessers des Mundstücks 2 verengt und eintrittsseitig mit einer trichterförmigen Erweiterung 14 versehen.A tool 11 is used for assembly, which has a through bore 12 which has a shoulder 13 up to which the mouthpiece 2 can be inserted into the tool 11. The passage bore 12 is narrowed above the shoulder 13 to a diameter equal to that of the collar 6 or the inside diameter of the mouthpiece 2 and is provided with a funnel-shaped extension 14 on the inlet side.

Der Berstkörper 4 mit dem im Bereich der Nut 7 befindlichen Haltering 10 wird von oben in die Durchtrittsbohrung 12 eingeführt. Hierbei wird der Haltering 10 zunächst in den tieferen Bereich 9 der Nut 7 geschoben und dann unter Zusammendrücken auf den Außendurchmesser des Bundes 6 von dem tieferen Bereich 9 der Nut 7 aufgenommen, so daß er mit dem Bund 6 des Berstkörpers 4 durch das Mundstück 2 der Treibladungshülse 1 hindurchgeschoben werden kann. Wenn der Haltering 10 den Bereich des Mundstücks 2 verlassen hat und sich im Bereich der schrägen Schulter 3 befindet, dehnt sich der Haltering 10 wieder aus und fällt in der Nut 7 in den heckseitigen Bereich 8 hiervon herunter.The bursting body 4 with the retaining ring 10 located in the area of the groove 7 is inserted into the through bore 12 from above. Here, the retaining ring 10 is first pushed into the deeper region 9 of the groove 7 and then taken up by compressing the outer diameter of the collar 6 from the deeper region 9 of the groove 7, so that it with the collar 6 of the bursting body 4 through the mouthpiece 2 Propellant charge sleeve 1 can be pushed through. When the retaining ring 10 has left the area of the mouthpiece 2 and is located in the area of the inclined shoulder 3, the retaining ring 10 expands again and falls in the groove 7 into the area 8 at the rear thereof.

Danach wird der Berstkörper 4 durch Hochziehen festgezogen, wodurch der Haltering 10 zwischen dem heckseitigen, flacheren Bereich 8 der Nut 7 und der schrägen Schulter 3 der Treibladungshülse 1 eingeklemmt wird.The bursting body 4 is then tightened by pulling it up, as a result of which the retaining ring 10 is clamped between the rear, shallower region 8 of the groove 7 and the oblique shoulder 3 of the propellant charge sleeve 1.

Hierdurch ergibt sich eine einfache, kostengünstige Montage der Manöverpatrone.This results in a simple, inexpensive assembly of the maneuvering cartridge.
