Description

Die vorliegende Erfindung bezieht sich auf ein Geschoss für eine Übungsmunition mit einer, einem scharfen Geschoss entsprechender, mindestens angenäherter Abgangs- und Aussenballistik und einer vorgegebenen Schussfeldbegrenzung.The present invention relates to a projectile for a practice ammunition with an at least approximate exit and outer ballistics corresponding to a live projectile and a predetermined firing field limitation.

Beim übungsweisen Einsatz von Geschossen besteht immer wieder die Gefahr, dass diese das vorgesehene Schussfeld verlassen und ausserhalb des Zielgebiets Schäden und/oder Verletzungen bewirken. Dementsprechend wurden verschiedene Lösungen vorgeschlagen, um vor allem in Ländern, in denen keine sehr grossflächigen Übungsplätze zur Verfügung stehen, das Schussfeld der Munition zu begrenzen. Gleichzeitig wurde jedoch versucht, das gegenüber einer scharfen Munition gleiche schiesstechnische Verhalten der Übungsmunition beizubehalten.When bullets are used in practice, there is always the danger that they will leave the intended firing field and cause damage and / or injuries outside the target area. Accordingly, various solutions have been proposed to limit the firing range of the ammunition, especially in countries where there are no very large practice areas available. At the same time, however, an attempt was made to maintain the same technical performance as the practice ammunition compared to live ammunition.

In der EP-A-0 080 210 (BETHMANN u.a.) ist ein Geschoss beschrieben und dargestellt, in dem axial ein stabilisierendes Element gelagert ist. Während des Abbrandes des Leuchtspur-satzes wird das stabilisierende Element frei und wird aus dem Geschoss herausgesogen bzw. herausgedrückt und zwar in der axialen Richtung nach hinten. Das stabilisierende Element bleibt weiter mit dem Rest des Geschosses mittels eines Drahtes verbunden. Diese Lösung ist also axial symmetrisch ausgebildet und somit ist die zu erwartende Abbremsung bzw. Destabilisierung des Geschosses verhältnismässig schwach.EP-A-0 080 210 (BETHMANN et al.) Describes and shows a projectile in which a stabilizing element is mounted axially. During the burn-up of the tracer set, the stabilizing element is released and is pulled out or pushed out of the projectile in the axial direction to the rear. The stabilizing element remains connected to the rest of the floor by means of a wire. This solution is therefore axially symmetrical and the expected deceleration or destabilization of the projectile is relatively weak.

Bekannt sind Zerfallgeschosse mit einer leichten Hülle und einem Kern aus Metallpulver (CH-PS 488 162 und CH-PS 488 989), welche zwar eine ähnliche Abgangsballistik aufweisen, jedoch aber schon nach kurzer Zeit beim Austritt aus dem Lauf auseinanderfallen, wodurch der gewünschte Übungswert der Munition verloren geht.Decay bullets with a light casing and a core made of metal powder (CH-PS 488 162 and CH-PS 488 989) are known, which, although they have a similar exit ballistics, but emerge after a short time the barrel fall apart, causing the desired practice value of the ammunition to be lost.

Ebenfalls bekannt sind Geschosse (CH-PS 539 834), die im Überschallbereich stabil und im Unterschallbereich unstabil fliegen, so dass deren aerodynamisches Verhalten das Schussfeld begrenzen.Bullets (CH-PS 539 834) are also known which fly stably in the supersonic area and unstably in the subsonic area, so that their aerodynamic behavior limits the field of fire.

Diese Munition simuliert den Abgang einer Gefechtsmunition und deren Flugverhalten innerhalb der Einsatzdistanz und ist nur zur Simulation von relativ grosskalibrigen Überschallgeschossen geeignet.This ammunition simulates the release of combat ammunition and its flight behavior within the operating distance and is only suitable for the simulation of relatively large-caliber supersonic projectiles.

Im weiteren sind Geschosse mit Selbstzerstörungsladungen bekannt (GB-A-2028982), welche jedoch aus Kosten- und auch aus Sicherheitsgründen (Gefahr von Blindgängern) für die meisten Anwendungen nicht in Frage kommen.In addition, bullets with self-destruct charges are known (GB-A-2028982), but for cost and security reasons (risk of unexploded ordnance) are out of the question for most applications.

Es ist daher Aufgabe der Erfindung, ein Geschoss zu schaffen, welches auf wirtschaftliche Weise eine sichere Schussfeldbegrenzung ergibt und zudem das Flugverhalten einer Gefechtsmunition wenigstens angenähert, sowohl in seiner Abgangs- als auch Aussenballistik, wiedergibt.It is therefore an object of the invention to provide a projectile which, in an economical manner, results in a safe firing field limitation and also at least approximates the flight behavior of a combat ammunition, both in terms of its outward and external ballistics.

Diese Aufgabe wird dadurch gelöst, dass im Geschosskörper ein Hohlraum mit einem pyrotechnischen Satz vorgesehen ist, welcher den Geschosskörper nach einer vorgegebenen Flugzeit partiell in einem Bereich der Oberfläche des Geschosses, unsymmetrisch in bezug auf die Achse des Geschosses, durchschmilzt und damit das Geschoss auf seiner Flugbahn entstabilisiert und begrenzt.This object is achieved in that a cavity with a pyrotechnic set is provided in the projectile body, which partially melts the projectile body after a predetermined flight time in an area of the surface of the projectile, asymmetrically with respect to the axis of the projectile, and thus the projectile on it Flight path destabilized and limited.

Die nachfolgenden abhängigen Ansprüche beinhalten bevorzugte Ausbildungen des Erfindungsgegenstandes.The following dependent claims contain preferred developments of the subject matter of the invention.

Bewährt hat sich der in Anspruch 2 genannte Leuchtspur-Satz, der das erforderliche wärmetechnische Verhalten aufweist und zudem eine einfache optische Verfolgung der Flugbahn des Geschosses erlaubt.Has proven the tracer set mentioned in claim 2, which has the required thermal behavior and it also allows simple optical tracking of the trajectory of the projectile.

Durch den Einbau einer wärmedämmenden Isolationshülse, gemäss Anspruch 3, lässt sich das Schmelzverhalten des Geschosses zeitlich und örtlich leicht bestimmen.By installing a heat-insulating sleeve, according to claim 3, the melting behavior of the projectile can be easily determined in terms of time and location.

Alternativ zur Isolationshülse lässt sich nach Anspruch 4 ein Isolationsnapf verwenden, der je nach gewählter Fabrikationsmethode Vorteile gegenüber einer Isolationshülse aufweist.As an alternative to the insulation sleeve, an insulation cup can be used according to claim 4, which has advantages over an insulation sleeve depending on the manufacturing method selected.

Bewährt hat sich eine Ausnehmung in der Isolationshülse bzw. im Isolationsnapf gemäss Anspruch 5, welche durch ihre asymmetrische Ausgestaltung das Geschoss innert einer vorgegebenen Zeit zielgerichtet mittels des pyrotechnischen Satzes durchschmelzen lässt. Durch die resultierende Unwucht wird das Geschoss destabilisiert und/oder es kreist durch den beim Abschuss erzeugten Drall exzentrisch um die Flugrichtung, wird stark gebremst und fällt auf den Boden.A cutout in the insulation sleeve or in the insulation cup according to claim 5 has proven its worth, and its asymmetrical design allows the projectile to melt through in a targeted manner within a predetermined time by means of the pyrotechnic sentence. The resulting imbalance destabilizes the projectile and / or it rotates eccentrically around the direction of flight due to the swirl generated during the launch, is braked strongly and falls to the ground.

Die in Anspruch 6 spezifizierten Isolationshülsen bzw. Isolationsnapfe sind besonders geeignet, da sie sich in einfachster Weise in einen Geschosskörper integrieren lassen und genau definierte wärmeleitende und wärmeabführende Eigenschaften aufweisen.The insulation sleeves or insulation cups specified in claim 6 are particularly suitable because they can be easily integrated into a projectile body and have precisely defined heat-conducting and heat-dissipating properties.

Bewährt haben sich Geschosse nach Anspruch 7, weil damit die erforderlichen Festigkeits- und ballistischen Eigenschaften leicht realisiert werden können und zudem der Schmelzpunkt der entsprechenden Legierung sich im Bereich von 580° C bis 600° C bewegt, welche Temperaturen durch einen einfachen, an sich bekannten pyrotechnischen Satz leicht erzielbar sind.Bullets according to claim 7 have proven useful because the required strength and ballistic properties can thus be easily achieved and, in addition, the melting point of the corresponding alloy is in the range from 580 ° C to 600 ° C, which temperatures by a simple, known per se pyrotechnic sentence are easily achievable.

Bei Geschossen, insbesondere im Unter- oder Transschallbereich fliegenden Raketen mit Leit- und/oder Stabilisierungsflossen, kann durch die Plazierung der Ausnehmung, entsprechend Anspruch 8, ein ganzes oder partielles Abschmelzen der Flossen erreicht werden, was die Destabilisierung und damit die präzise Begrenzung der Flugbahn verbessert.In the case of projectiles, in particular rockets with guiding and / or stabilizing fins flying in the subsonic or trans-sound area, the placement of the recess can correspond chend claim 8, a complete or partial melting of the fins can be achieved, which improves the destabilization and thus the precise limitation of the trajectory.

Besonders günstig ist die Verwendung des Geschosses gemäss Anspruch 9, da damit die Gefahr von Verletzungen in der Übung und Ausbildung verringert wird.The use of the projectile according to claim 9 is particularly favorable since it reduces the risk of injuries during exercise and training.

Nachfolgend wird anhand von Zeichnungen ein bevorzugtes Ausführungsbeispiel der Erfindung näher beschrieben.A preferred exemplary embodiment of the invention is described in more detail below with reference to drawings.

In sämtlichen Figuren sind für gleiche Teile gleiche Bezugsziffern verwendet worden.In all figures, the same reference numerals have been used for the same parts.

Nach Fig. 1 ist ein Geschoss mit 1 bezeichnet. Dieses Geschoss weist einen Vorderteil 2 auf, welches in bekannter Weise aerodynamisch optimiert ist und das Flugverhalten eines scharfen Geschosses aufweist. Ein nutförmiger Abschnitt 3 (Eindrehung) dient in gewohnter Weise zur Befestigung der Patronenhülse. Ein Mittelteil 4 des Geschosses 1 besitzt im Bereich seines hinteren Endes 5 eine stirnseitige Bohrung, welche eine Isolationshülse 8 und in dieser einen Leuchtspur-Satz 6 enthält, der durch einen ebenfalls an sich bekannten Anfeuer-Satz 10, 11, 12 gezündet werden kann.1, a floor is designated by 1. This projectile has a front part 2, which is aerodynamically optimized in a known manner and has the flight behavior of a sharp projectile. A groove-shaped section 3 (screwing) is used in the usual way to attach the Cartridge case. A middle part 4 of the projectile 1 has in the area of its rear end 5 an end bore which contains an insulation sleeve 8 and in this a tracer set 6 which can be ignited by a lighting set 10, 11, 12 which is also known per se.

Die Isolationshülse 8 weist Ausnehmungen 9, 9' auf, welche ebenfalls durch den Leuchtspur-Satz ausgefüllt sind.The insulation sleeve 8 has recesses 9, 9 ', which are also filled in by the tracer set.

Fig. 2 zeigt das Geschoss 1 mit seinen vorgängig beschriebenen Bestandteilen nochmals, jedoch in einer verkleinerten Ausführung und mit einer teilweise gezeichneten Patronenhülse 14 , der Befestigungsstelle 15, ihrer Würgerille 16 und - nicht spezifisch dargestellt - der Pulverladung 17.FIG. 2 shows the projectile 1 again with its previously described components, but in a reduced version and with a partially drawn cartridge case 14, the attachment point 15, its gag groove 16 and - not specifically shown - the powder charge 17.

Das Geschoss besteht aus einer Hartbleilegierung (Blei-Antimon) und weist einen Schmelzpunkt von zirka 580° C auf.The bullet consists of a hard lead alloy (lead-antimony) and has a melting point of around 580 ° C.

Die Isolationshülse 8 ist in Fig. 3 in einem Schnitt A - A einzeln dargestellt. Daraus ist leicht ersichtlich, dass die Ausnehmungen 9, 9' durch einfaches geradliniges, stirnseitiges Abfräsen der Hülse bis zu ihrem Zentrum erzeugt werden kann.The insulation sleeve 8 is shown individually in FIG. 3 in a section AA. It is easy to see from this that the recesses 9, 9 'can be produced by simple straight-line milling of the end face of the sleeve up to its center.

Der an sich bekannte Leuchtspur-Satz wurde nach dem Einbringen der Hülse 8 in das Geschoss 1 eingepresst und durch stirnseitiges Bördeln mit dem in Fig. 1 bezeichneten kegelstumpfförmigen Abschnitt fixiert.The known tracer set was pressed into the projectile 1 after the sleeve 8 had been introduced and fixed with the frustoconical section shown in FIG.

In einem praktischen Beispiel gelten folgende Werte:

  • Masse des Geschosses: 10 g; Kaliber 7,5 mm
  • Legierung des Geschosses: Hartblei (98 Gew.-% Pb, 2 Gew.-% Sb)
  • Isolationshülse gemäss Fig. 3: aus Polyamid (Nylon) Aussendurchmesser der Hülse: 6 mm
  • Innendurchmesser der Hülse: 4,5 mm
  • Länge der Hülse: 8 mm
  • Abfräsung: 180° / 3 mm in der Länge
  • Leuchtspur-Satz: Standard Infanterie-Munition 7,5 mm Treibladung: Standard Schiesspulver Kleinkaliber-Munition Flugdistanz des Geschosses: max. 3'000 m
  • Einsatzdistanz: 200 bis 500 m
  • Flugdauer bis zum Auftreffen auf den Boden: ca. 1,5 Sek.
In a practical example, the following values apply:
  • Weight of the bullet: 10 g; 7.5 mm caliber
  • Bullet alloy: hard lead (98 wt% Pb, 2 wt% Sb)
  • 3: made of polyamide (nylon) outer diameter of the sleeve: 6 mm
  • Inner diameter of the sleeve: 4.5 mm
  • Length of the sleeve: 8 mm
  • Milling: 180 ° / 3 mm in length
  • Tracer set: standard infantry ammunition 7.5 mm propellant: standard gun powder small-caliber ammunition Flight distance of the projectile: max. 3,000 m
  • Operating distance: 200 to 500 m
  • Flight time to hit the ground: approx. 1.5 seconds

Die Variante gemäss Fig. 4 weist dieselben Eigenschaften wie die Lösung gemäss Fig. 1 auf. Aus vorwiegend fabrikationstechnischen Gründen ist jedoch anstelle einer Isolationshülse 8 ein Isolationsnapf 8' verwendet worden.The variant according to FIG. 4 has the same properties as the solution according to FIG. 1. For mainly manufacturing reasons, however, an insulation cup 8 'has been used instead of an insulation sleeve 8.

Die Darstellung Fig. 5 zeigt den Isolationsnapf 8', ebenfalls aus Nylon, in einer Ansicht auf dessen Längsachse.The illustration in FIG. 5 shows the insulation cup 8 ', also made of nylon, in a view on its longitudinal axis.

Diese Variante hat den Vorteil, dass der pyrotechnische Satz vollständig vorbereitet in den Napf 8' eingepresst und nachträglich als Gesamtes in den Geschosskörper eingesetzt werden kann. Zudem lässt sich die Wärmeleitung des Satzes noch besser vorausbestimmen.This variant has the advantage that the pyrotechnic set, fully prepared, can be pressed into the cup 8 'and subsequently inserted as a whole into the projectile body. In addition, the heat conduction of the set can be predicted even better.

Der Erfindungsgegenstand ist insbesondere bei Verwendung eines Leuchtspur-Satzes ebenfalls für grössere Geschosse geeignet. Je nach Art der verwendeten Isolationshülse bzw. des Isolationsnapfes entsteht bei der Übungsmunition eine ablative Wirkung. Die Wärmeabfuhr in der Form des geschmolzenen oder zersetzten Kunststoffs nach hinten verhindert einen möglichen grösseren Wärmestau bei grösseren Kalibern und damit ein unerwünschtes, vorzeitiges Durchschmelzen des Mantels.The subject of the invention is also particularly suitable for larger storeys when using a tracer set. Depending on the type of insulation sleeve used or the insulation cup, an ablative effect occurs with the practice ammunition. The heat dissipation in the form of the melted or decomposed plastic to the rear prevents a possible greater build-up of heat with larger calibres and thus an undesirable, premature melting of the jacket.
