Description
Geschoss für eine Ausbildungs-Kurzfoahnmunition Projectile for training short-range ammunition
Die Erfindung betrifft ein Geschoss für die Schießausbildung an Handfeuerwaffen, wie Gewehren, Pistolen auf kurzen Schießbahnen.The invention relates to a projectile for firing training on small arms, such as rifles, pistols on short firing lanes.
Üblicherweise wird in der Schießausbildung überwiegend die Gefechtspatrone 5,56 mm x 45 benutzt. Diese Patrone hat zwar den Vorteil, dass das Schießverhalten den realistischen Umständen" entspricht. Nachteilig ist jedoch, dass eine erhebliche Zerstörung der Zielmedien, d.h. der Scheiben und der dahinter liegenden Geschossfänge auftritt und dass die derzeit verwendeten Übungspatronen einen Gefahrenbereich von mehr als 1200 m besitzen, was aufwendige Schutzmaßnahmen an der Schießbahn bedingt.Usually the combat cartridge 5.56 mm x 45 is mainly used in shooting training. Although this cartridge has the advantage that the shooting behavior corresponds to the realistic circumstances. "However, the disadvantage is that a significant destruction of the target media that is, the washers and the underlying basement catches, and maintain the training cartridges currently used have a dangerous area of more than 1200 m , which requires complex protective measures on the shooting range.
Aufgabe der Erfindung ist es, den Umgang mit Übungspatronen zu vereinfachen und sicherer zu gestalten.The object of the invention is to simplify the handling of exercise cartridges and to make them safer.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.
Die Erfindung schlägt vor, im in Flugrichtung vorderen Teil des Geschosses, wo die Luft während des Fluges anströmt, eine Reduzierungsvorrichtung für die Geschwindigkeit vorzusehen. Damit verringert sich die Geschwindigkeit und auch die kinetische Energie des Geschosses, so dass die Beschädigungen der Zielmedien verringert und der Gefahrenbereich verkleinert wird. Erfindungsgemäß sind zwei Varianten zur Reduzierung der Geschwindigkeit vorgesehen. Beide Varianten können jeweils einzeln oder kombiniert angewendet werden.The invention proposes to provide a speed reduction device in the front part of the projectile in the direction of flight, where the air flows in during flight. This reduces the speed and also the kinetic energy of the projectile, so that damage to the target media is reduced and the danger zone is reduced. According to the invention, two variants are provided for reducing the speed. Both variants can be used individually or in combination.
Gemäß der ersten Variante weist die Reduzierungsvorrichtung im Bereich der Geschossspitze eine senkrecht zur Flugrichtung verlaufende Bremsfläche auf. So wird eine Anströmfläche mit ungünstigem Cw-Wert erzeugt, wodurch die Geschossgeschwindigkeit reduziert wird und die außenballistische Leistung gesteuert wird, wobei dies von der Auslegung des Durchmessers und der Geschossmasse abhängt. Diese Variante hat den Vorteil, dass sie leicht herzustellen ist und die Geschwindigkeit des Geschosses bereits wirksam reduziert.According to the first variant, the reducing device in the area of the projectile tip has a braking surface running perpendicular to the direction of flight. This creates an inflow surface with an unfavorable Cd value, which reduces the projectile speed and controls the external ballistic performance, this being based on the design of the diameter and the projectile mass depends. This variant has the advantage that it is easy to manufacture and already effectively reduces the speed of the projectile.
Vorteilhafterweise ist in der Bremsfläche eine konkave Ausnehmung vorhanden, die bewirkt, dass die auf die Bremsfläche anströmende Luft definiert an den Umfang des Geschosses abgeleitet wird, so dass an der Geschossspitze keine das Geschoss übermäßig destabilisierende Strömungen oder Verwirbelungen entstehen.Advantageously, there is a concave recess in the braking surface, which causes the air flowing onto the braking surface to be discharged to the circumference of the projectile in a defined manner, so that no currents or eddies which excessively destabilize the projectile occur at the projectile tip.
Gemäß der zweiten Variante der Erfindung weist die Reduzierungsvorrichtung im vorderen Teil der Umfangsfläche des Geschosses mindestens eine in Längsrichtung verlaufende Widerstandsfläche zur Reduzierung des Geschossdralls, also der Drehzahl des Geschosses auf. Die Widerstandsfläche bewirkt, dass der dem Geschoss beim Abschuss mitgegebene Drall so weit reduziert wird, dass das Geschoss instabil wird. Dies hat zur Folge, dass das Geschoss zu pendeln beginnt, wodurch die Geschwindigkeit reduziert wird. Von Vorteil ist herbei, dass die Geschwindigkeit aufgrund der Geschosspendelung erheblich reduziert wird.According to the second variant of the invention, the reducing device has in the front part of the peripheral surface of the projectile at least one resistance surface running in the longitudinal direction for reducing the projectile twist, that is to say the speed of the projectile. The resistance surface causes the swirl imparted to the projectile to be reduced to such an extent that the projectile becomes unstable. As a result, the projectile begins to oscillate, reducing the speed. It is advantageous that the speed is considerably reduced due to the leveling of the projectiles.
Vorteilhafterweise weist die Umfangsfläche einen in Drehrichtung des Geschosses vor der Widerstandsfläche angeordneten sich radial verringernden konischen Bereich auf, so dass sich die Widerstandsfläche vom Umfang des Geschosses in Richtung der Mittelachse des Geschosses erstreckt. Dieser Aufbau ist sehr stabil, da die Widerstandsfläche gewissermaßen aus dem vollem Material ausgenommen wird.Advantageously, the circumferential surface has a radially reducing conical region arranged in front of the resistance surface in the direction of rotation of the projectile, so that the resistance surface extends from the circumference of the projectile in the direction of the central axis of the projectile. This structure is very stable, since the resistance surface is, so to speak, excluded from the full material.
Es können auch mehrere, vorzugsweise vier, um jeweils 90° auf dem Umfang versetzte Widerstandsflächen vorgesehen sein. Die Erhöhung der Anzahl der Widerstandsflächen bedingt eine Verstärkung der Reduzierung des Geschossdralls.A plurality of, preferably four, resistance surfaces offset by 90 ° on the circumference can also be provided. The increase in the number of resistance areas requires an increase in the reduction in the swirl of the projectile.
Auch eine spiralförmige Ausbildung der Widerstandsfläche kann den Geschossdrall weiter reduzieren, da die Fläche der Widerstandsfläche durch die spiralförmige Anordnung um den Umfang des Geschosses erheblich vergrößert wird. Beide Varianten, vor allem die Kombination der beiden Varianten, bewirkt, dass die Geschossgeschwindigkeit reduziert und damit die Höchstschussweite verkürzt wird, was zu einem verkleinerten Gefahrenbereich und zu einer Verringerung der Beschädigungen der Zielmedien führt. Dies wird erreicht, ohne dass Änderungen an der Waffe vorgenommen werden müssen.A spiral configuration of the resistance surface can also further reduce the projectile swirl, since the surface of the resistance surface is considerably enlarged by the spiral arrangement around the circumference of the projectile. Both variants, especially the combination of the two variants, causes the projectile speed to be reduced and thus the maximum range to be shortened, which leads to a reduced danger zone and to less damage to the target media. This is achieved without having to make changes to the weapon.
Mittels der Abmessungen und der Anordnung der Bremsfläche und/oder der Widerstandsfläche bzw. der Widerstandsflächen lässt sich die Reduzierung der Geschwindigkeit bzw. die Höchstschussweite definiert einstellen. So ist es möglich, Übungspatronen für unterschiedliche Anforderungen zu schaffen. Beispielsweise ist es möglich, den Gefahrenbereich auf unter 650 m zu reduzieren und eine Geschoss- Treffpunktlage" bei 100 m Übungsentfernung einzustellen, die mit der des Gefechtsgeschosses vergleichbar ist.By means of the dimensions and the arrangement of the braking surface and / or the resistance surface or the resistance surfaces, the reduction in speed or the maximum range can be set in a defined manner. So it is possible to create practice cartridges for different requirements. For example, it is possible to reduce the danger zone to less than 650 m and to set a floor meeting point location " at 100 m training distance, which is comparable to that of the combat floor.
Im folgenden werden anhand der Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.
Es zeigen:Show it:
Fig. 1 ein erfindungsgemäßes Geschoss in Seitenansicht, undFig. 1 shows a projectile according to the invention in side view, and
Fig. 2 eine Schnittdarstellung gemäß Linie ll-ll in Fig. 1.FIG. 2 shows a sectional view along line II-II in FIG. 1.
Figur 1 zeigt ein Geschoss 1 mit einem zylinderförmigen Geschosskörper 2. Der Geschosskörper 2 besteht aus einem hinteren Teil 3 und einem vorderen Teil 4.FIG. 1 shows a projectile 1 with a cylindrical projectile body 2. The projectile body 2 consists of a rear part 3 and a front part 4.
Der hintere Teil 3 nimmt etwa die halbe Länge des Geschosses 1 ein. Der hintere Teil 3 bildet das Geschossführungsteil und kann überkalibrig ausgeführt sein, wodurch der Einpresswiderstand des Geschosses in den Rohrübergang erhöht wird, was zu einem guten Treibmittelabbrand und zu einer besseren Abdichtung gegen Gasschlupf führt. Das Ende 5 des hinteren Teils 3 ist konkav ausgebildet. Der vordere Teil 4 des Geschosskörpers 2 endet in der Geschossspitze 6. An dem vorderen Teil 4 ist eine Reduzierungsvorrichtung 7 für die Geschwindigkeit vorgesehen. Die Reduzierungsvorrichtung 7 enthält eine an der Geschossspitze 3 angeordnete Bremsfläche 7a und mehrere " am Umfang 8 angeordnete Widerstandsflächen 7b.The rear part 3 takes up about half the length of the projectile 1. The rear part 3 forms the projectile guide part and can be of over-caliber design, whereby the pressing resistance of the projectile into the pipe transition is increased, which leads to good propellant burn-up and to a better seal against gas slip. The end 5 of the rear part 3 is concave. The front part 4 of the projectile body 2 ends in the projectile tip 6. A reduction device 7 for the speed is provided on the front part 4. The reduction mechanism 7 includes a arranged on the projectile tip 3 braking surface 7a and several "on the periphery 8 arranged resistance surfaces 7b.
Die Bremsfläche 7a ist senkrecht zur Geschosslängsachse und damit auch senkrecht zur Flugrichtung des Geschosses 1 angeordnet. In der Bremsfläche 7a ist eine konkave Ausnehmung 9 vorhanden. Die konkave Ausnehmung 9 ist mittig in der Bremsfläche 7a angeordnet, d.h. dass der Mittelpunkt der konkaven Ausnehmung 9 auf der Längsachse des Geschosskörpers 2 liegt.The braking surface 7a is arranged perpendicular to the longitudinal axis of the projectile and thus also perpendicular to the direction of flight of the projectile 1. A concave recess 9 is present in the braking surface 7a. The concave recess 9 is arranged centrally in the braking surface 7a, i.e. that the center of the concave recess 9 lies on the longitudinal axis of the projectile body 2.
Die Widerstandsflächen 7b, die den zweiten Teil der Reduzierungsvorrichtung 7 bilden, sind an der Umfangsfläche 8 angeordnet und verlaufen parallel zur Flugrichtung des Geschosses 1. Die am Umfang liegende äußere Kante und die innere Kante der Widerstandsfläche 7b verlaufen parallel, so dass die Widerstandsfläche 7b bedingt durch die konischen Bereiche an der Geschossspitze 3 und am Übergangsbereich zwischen hinterem Teil 3 und vorderem Teil 4 eine in etwa parallelogrammförmige Fläche aufweist. Denkbar sind jedoch auch zahlreiche andere Formen, wie zum Beispiel eine Dreiecksform.The resistance surfaces 7b, which form the second part of the reduction device 7, are arranged on the peripheral surface 8 and run parallel to the direction of flight of the projectile 1. The outer edge lying on the circumference and the inner edge of the resistance surface 7b run parallel, so that the resistance surface 7b is conditional has an approximately parallelogram-shaped area due to the conical areas at the projectile tip 3 and at the transition area between the rear part 3 and the front part 4. However, numerous other shapes are also conceivable, such as a triangular shape.
Wie in Fig. 2 gezeigt ist, sind vier Widerstandsflächen 7b in gleichmäßigen Abstand, also um 90° versetzt, über die Umfangsfläche 8 verteilt. Die Drehrichtung des Geschosses 1 ist durch die Pfeile angezeigt. In Drehrichtung des Geschosses 1 ist vor jeder Widerstandsfläche 7a ein sich radial verringernder konischer Bereich 10 vorgesehen. Direkt vor einer Widerstandsfläche 7b ist der Radius am kleinsten und am anderen Ende des konischen Bereichs 10 ist der Radius am größten. Dort befindet sich ein Absatz in der Umfangsfläche 8, der die nächste Widerstandsfläche 7b bildet. Anders ausgedrückt verbindet eine Widerstandsfläche 7b zwei konische Bereiche 10, wobei der eine konische Bereich an der Widerstandsfläche seinen kleinsten Radius hat, während der andere konische Bereich dort seinen größten Radius aufweist. Im folgenden wird das Flugverhalten des Geschosses 1 beschrieben. Durch Abbrennen des Treibmittels wird das Geschoss 1 in dem Lauf einer Schusswaffe beschleunigt, wobei es aufgrund der Laufgeometrie eine Drallbewegung zur Flugstabilisierung erhält. Ohne die erfindungsgemäße Reduzierungsvorrichtung 7 würde ein Geschoss stabil und weit fliegen, da ein übliches Geschoss mit einer spitz zulaufenden Geschossspitze einen sehr geringen Cw-Wert hat. Bei dem erfindungsgemäßen Geschoss 1 wird die Geschwindigkeit des Geschosses 1 durch die Bremsfläche 7a und die Widerstandsflächen 7b reduziert, so dass Reichweite und Durchschlagskraft verringert werden.As shown in FIG. 2, four resistance surfaces 7b are distributed over the circumferential surface 8 at a uniform distance, that is to say offset by 90 °. The direction of rotation of floor 1 is indicated by the arrows. In the direction of rotation of the projectile 1, a radially decreasing conical region 10 is provided in front of each resistance surface 7a. The radius is smallest in front of a resistance surface 7b and the radius is largest at the other end of the conical region 10. There is a shoulder in the peripheral surface 8, which forms the next resistance surface 7b. In other words, a resistance surface 7b connects two conical regions 10, one conical region having its smallest radius on the resistance surface, while the other conical region has its largest radius there. The flight behavior of the projectile 1 is described below. By firing the propellant, the projectile 1 is accelerated in the barrel of a firearm, and because of the barrel geometry it receives a swirl movement for flight stabilization. Without the reduction device 7 according to the invention, a projectile would fly stably and far, since a conventional projectile with a tapering projectile tip has a very low Cd value. In the projectile 1 according to the invention, the speed of the projectile 1 is reduced by the braking surface 7a and the resistance surfaces 7b, so that the range and penetration force are reduced.
Die das Geschoss von vorne anströmende Luft trifft zunächst auf die Bremsfläche 7a und die darin angeordnete konkave Ausnehmung 9 auf. Dies bewirkt eine erste Verringerung der Geschossgeschwindigkeit bei weiterhin stabiler Fluglage des Geschosses 1. Gleichzeitig dreht sich das Geschoss 1 um seine Längsachse, wobei die Widerstandsfläche 7b einen Luftwiderstand bilden, der den Drall des Geschosses 1 verringert, wodurch die Fluglage immer unstabiler wird, bis das Geschoss 1 zu pendeln beginnt. Dies bewirkt einen weiteren Geschwindigkeitsabfall des Geschosses 1. Die Stärke und Richtung der Pendelbewegung wird durch die Anordnung und die Größe der Widerstandsflächen 7b bestimmt.The air flowing in from the front hits the braking surface 7a and the concave recess 9 arranged therein. This causes a first reduction in the projectile speed while the flight position of the projectile 1 remains stable. At the same time, the projectile 1 rotates about its longitudinal axis, the resistance surface 7b forming an air resistance which reduces the swirl of the projectile 1, as a result of which the flight position becomes increasingly unstable until the Floor 1 begins to oscillate. This causes a further drop in the velocity of the projectile 1. The strength and direction of the pendulum movement is determined by the arrangement and the size of the resistance surfaces 7b.
Der Geschosskörper 2 besteht vorzugsweise aus einem biologisch abbaubaren Kunststoff, der mit einem Metall gefüllt ist. Dadurch lässt sich die Umweltbelastung reduzieren. The projectile body 2 preferably consists of a biodegradable plastic which is filled with a metal. This can reduce the environmental impact.
