Description

Die Erfindung betrifft einen Waffensimulator zur Erprobung der Entnahme von Munition aus einem Magazin mit der Kadenz einer selbsttätigen Feuerwaffe.The invention relates to a weapon simulator for testing the removal of ammunition from a magazine with the cadence of an automatic firearm.

Um aus einer selbsttätigen Feuerwaffe ein Seriefeuer auszulösen, ist ein Munitionsmagazin mit einer Fördervorrichtung notwendig, mit der aus dem Magazin die für das Seriefeuer benötigte Munition der selbsttätigen Feuerwaffe zugeführt wird.In order to trigger a series fire from an automatic firearm, an ammunition magazine with a conveyor device is necessary with which the ammunition required for the series fire is fed to the automatic firearm.

Zum Erproben der Funktion der Fördervorrichtung und des Magazins,aus dem die Munition beim Seriefeuer mit Hilfe der Fördervorrichtung entnommen wird, ist ein Waffensimulator erforderlich, der die selbsttätige Feuerwaffe ersetzt.To test the function of the conveyor and the magazine from which the ammunition is removed from the series fire using the conveyor, a weapon simulator is required to replace the automatic firearm.

Mit der Feuerwaffe kann die Munition für ein Seriefeuer dem Magazin nur entnommen werden, wenn es sich um scharfe Munition handelt, welche in der Feuerwaffe sogleich verschossen wird, denn ohne die in der scharfen Munition vorhandene Treibladung fehlt die Energie zur Betätigung der Feuerwaffe.With the firearm, the ammunition for a series fire can only be removed from the magazine if it is live ammunition, which is immediately fired in the firearm, because without the propellant charge present in the live ammunition there is no energy to operate the firearm.

Wenn die Verwendung von scharfer Munition bei der Erprobung von Fördervorrichtung und Magazin vermieden werden soll, dann muss die selbsttätige Feuerwaffe durch einen Waffensimulator ersetzt werden, der in der Lage ist, Manipulierpatronen mit der gleichen Kadenz wie die Feuerwaffe aus dem Magazin mit Hilfe der Fördervorrichtung zu entnehmen.If the use of live ammunition is to be avoided when testing the conveyor and magazine, then the automatic firearm must be replaced by a weapon simulator that is capable of manipulating cartridges with the same cadence as the firearm from the magazine using the conveyor remove.

Die Aufgabe, welche mit der vorliegenden Erfindung gelöst werden soll, besteht in der Schaffung eines Waffensimulators, der die Munition in der selben Weise wie eine Feuerwaffe mit Hilfe der Fördervorrichtung aus einem Muntionsmagazin entnimmt, d.h. die Beschleunigungen und Verzögerungen der Munition, die bei der Entnahme der Munition während eines Seriefeuers aus einer selbsttätigen Feuerwaffe auftreten, sollen mit Hilfe des Waffensimulators ebenfalls erzeugt werden.The object to be achieved with the present invention is to provide a weapon simulator which extracts the ammunition from an ammunition magazine in the same way as a firearm with the aid of the conveyor device, i.e. the accelerations and decelerations of the ammunition, which occur when the ammunition is removed from a series fire from an automatic firearm, are also to be generated with the aid of the weapon simulator.

Es sind Waffensimulatoren dieser Art bekannt, die sich jedoch nur für spezielle Waffen eignen und die oben genannte Aufgabe nicht erfüllen.Weapon simulators of this type are known, but are only suitable for special weapons and do not fulfill the above-mentioned task.

Der erfindungsgemässe Waffensimulator ist gekennzeichnet durch

  • - zwei Nockenscheiben zum Fördern von Patronen,
  • - eine Welle, auf der die Nockenscheiben im Abstand voneinander befestigt sind,
  • - einen Motor zum Antreiben der Welle,
  • - einen Zuführkanal, durch den die Patronen gegen die Nockenscheiben geschoben werden, und
  • - einen Ableitkanal,, durch den die Patronen von den Nockenscheiben ausgestossen werden.
The weapon simulator according to the invention is characterized by
  • - two cam disks for conveying cartridges,
  • a shaft on which the cam disks are fastened at a distance from one another,
  • - a motor for driving the shaft,
  • a feed channel through which the cartridges are pushed against the cam disks, and
  • - A discharge channel, through which the cartridges are ejected from the cam discs.

Ein Ausführungsbeispiel des erfindungsgemässen Waffensimulators ist anhand der beigefügten Zeichnung im folgenden ausführlich beschrieben. Es zeigt:

  • Fig. l einen Längsschnitt durch den Waffensimulator nach Linie I-I in Fig. 2 und
  • Fig. 2 einen Querschnitt durch den Waffensimulator nach Linie II-II in Fig. l in vergrössertem Massstab.
An embodiment of the weapon simulator according to the invention is described in detail below with reference to the accompanying drawing. It shows:
  • Fig. L shows a longitudinal section through the weapon simulator according to line II in Fig. 2 and
  • Fig. 2 shows a cross section through the weapon simulator according to line II-II in Fig. L on an enlarged scale.

Gemäss Fig. 1 weist der Waffensimulator einen handelsüblichen Hydromotor 10 auf. Dieser Hydromotor 10 ist über eine Zuführleitung 11 und eine Rücklaufleitung 12 an eine nicht dargestellte Druckmittelquelle angeschlossen. Durch einen Hahnen 13 kann die Zuführleitung 11 gesperrt werden, wodurch der Hydromotor stillsteht. Der Hydromotor 10 besitzt einen Antriebszapfen 14, der über einen Keil 15 eine Welle 16 antreibt. Der Hydromotor 10 ist an einer Wand 17 eines nicht näher dargestellten Gehäuses befestigt, und die Welle 16 ist an einer zweiten Wand 18 dieses Gehäuses drehbar gelagert. Auf dieser Welle 16 sind'zwei Nockenscheiben 19, 20 und ein erstes Zahnrad 21 mit Hilfe von Keilen 22, 23 und 24 befestigt. Das erste Zahnrad 21 steht mit einem zweiten Zahnrad 25 in Eingriff, das mit Hilfe eines Zapfens 26 an der Gehäusewand 18 drehbar gelagert ist. Koaxial zum zweiten Zahnrad 25 ist ein Tachometer 27 angeordnet, der über einen Kurbelarm 28 und einen Bolzen 29 vom zweiten Zahnrad 25 angetrieben wird. Der Bolzen 29 ragt in eine Bohrung 30 des Zahnrades 25. Auf das linke Ende der Welle 16 kann eine Handkurbel 31 aufgesteckt werden, von der in Fig. 1 nur das Ende dargestellt ist.1, the weapon simulator has a commercially available hydraulic motor 10. This hydraulic motor 10 is connected via a feed line 11 and a return line 12 to a pressure medium source, not shown. The supply line 11 can be blocked by a cock 13, as a result of which the hydraulic motor comes to a standstill. The hydraulic motor 10 has a drive pin 14 which drives a shaft 16 via a wedge 15. The hydraulic motor 10 is fastened to a wall 17 of a housing, not shown, and the shaft 16 is rotatably mounted on a second wall 18 of this housing. Two cam disks 19, 20 and a first gearwheel 21 are fastened on this shaft 16 by means of wedges 22, 23 and 24. The first gear 21 is in engagement with a second gear 25 which is rotatably mounted on the housing wall 18 by means of a pin 26. A tachometer 27 is arranged coaxially with the second gear wheel 25 and is driven by the second gear wheel 25 via a crank arm 28 and a bolt 29. The bolt 29 protrudes into a bore 30 of the gear wheel 25. A hand crank 31 can be slipped onto the left end of the shaft 16, only the end of which is shown in FIG. 1.

Gemäss Fig. 2 weist der Waffensimulator einen Zuführkanal 34 für die Patronen auf, der einerseits durch eine Deckplatte 32 und andererseits durch eine Führungsstrebe 33 gebildet wird. Ausserdem ist ein Ableitkanal 35 für die Patronen vorhanden, der durch zwei Führungswände 36 und 37 gebildet wird. An der einen Führungswand 36 ist ein Sender 38 und an der anderen Führungswand 37 ist ein Empfänger 39 befestigt. Mit Sender 38 und Empfänger 39 können die durch den Ableitkanal hindurchgehenden Patronen gezählt werden. Die Drehrichtung der Welle 16 mit den Nockenscheiben 19, 20 ist in Fig. 2 durch einen Pfeil 40 angedeutet.2, the weapon simulator has a feed channel 34 for the cartridges, which is formed on the one hand by a cover plate 32 and on the other hand by a guide strut 33. There is also a discharge channel 35 for the cartridges, which is formed by two guide walls 36 and 37. A transmitter 38 is attached to one guide wall 36 and a receiver 39 is attached to the other guide wall 37. The cartridges passing through the discharge channel can be counted with transmitter 38 and receiver 39. The direction of rotation of the shaft 16 with the cam disks 19, 20 is indicated in FIG. 2 by an arrow 40.

Die Wirkungsweise des beschriebenen Waffensimulators ist wie folgt:The weapon simulator works as follows:

Der Hydromotor 10 wird mit der gewünschten Drehzahl angetrieben, entsprechend der Kadenz der Feuerwaffe, d.h. z.B. 380-700 Schuss pro Minute. Vorzugsweise wird die Drehzahl des Hydromotors 10 durch einen an sich bekannten Regelkreis gesteuert. Zu diesem Regelkreis gehört insbesondere der in Fig. l dargestellte Tachometer 27. Da die Welle 16 mit den Nockenscheiben 19 und 20 zur Förderung einer Patrone eine Umdrehung ausführt, wird die Drehzahl des Hydromotors ebenfalls zwischen 380-700 Umdrehung pro Minute liegen.The hydraulic motor 10 is driven at the desired speed, corresponding to the cadence of the firearm, i.e. e.g. 380-700 rounds per minute. The speed of the hydraulic motor 10 is preferably controlled by a control circuit known per se. The tachometer 27 shown in FIG. 1 belongs in particular to this control loop. Since the shaft 16 rotates with the cam disks 19 and 20 to convey a cartridge, the speed of the hydraulic motor will also be between 380-700 revolutions per minute.

Die Form der Kurvenscheiben 19 und 20 ist aus Fig. 2 ersichtlich. Diese Form der Kurvenscheibe 19 und 20 kann den Eigenschaften der selbsttätigen Feuerwaffe angepasst werden, d.h. Beschleunigungen und Verzögerungen der im Zuführkanal 34 befindlichen Patronen sollen soweit nachvollzogen werden, wie dies zur Erprobung des Munitionsmagazins und der Fördervorrichtung erforderlich ist. Diese in der Zeichnung nicht dargestellte Fördervorrichtung transportiert die Patronen aus dem ebenfalls nicht dargestellten Munitionsmagazin in den Zuführkanal 34 und drückt die Patronen gegen die beiden Nockenscheiben 19 und 20.The shape of the cams 19 and 20 can be seen in FIG. 2. This shape of the cam 19 and 20 can be adapted to the properties of the automatic firearm, i.e. Accelerations and decelerations of the cartridges located in the feed channel 34 are to be traced as far as is necessary to test the ammunition magazine and the conveyor device. This conveyor device, not shown in the drawing, transports the cartridges from the ammunition magazine, also not shown, into the feed channel 34 and presses the cartridges against the two cam disks 19 and 20.

Bei jeder Umdrehung der Welle 16 wird mit der Nase der Nockenscheiben 19, 20 eine Patrone aus dem Zuführkanal 34 in den Ableitkanal 35 gefördert.With each revolution of the shaft 16, a cartridge is conveyed from the feed channel 34 into the discharge channel 35 with the nose of the cam disks 19, 20.

Gemäss Fig. 2 liegt eine Patrone P an der Nockenscheibe 19 an und zwar an einer Stelle, die in einem Abschnitt der Kurve einen konstanten Radius aufweist. Solange die Patrone an diesem Abschnitt der Nockenscheibe 19 anliegt, wird sie sich nicht bewegen. Sobald der Radius der Nockenscheibe 19 kleiner wird, verschiebt sich die Patrone, gemäss Fig. 2, nach rechts.2, a cartridge P rests against the cam disk 19, specifically at a point which has a constant radius in a section of the curve. As long as the cartridge rests against this section of the cam disk 19, it will not move. As soon as the radius of the cam disk 19 becomes smaller, the cartridge shifts to the right, as shown in FIG. 2.

Sobald die Patrone P ausgestossen wird, erfolgt eine raschere Verschiebung der nächstfolgenden Patrone nach rechts bis sie die Nockenscheibe 19 berührt. Somit werden die Patronen mit verschiedenen Geschwindigkeiten gefördert und erfahren Beschleunigungen und Verzögerungen, die denjenigen einer selbsttätigen Feuerwaffe entsprechen.As soon as the cartridge P is ejected, the next cartridge that follows is shifted more rapidly to the right until it touches the cam disk 19. The cartridges are thus conveyed at different speeds and experience accelerations and decelerations that correspond to those of an automatic firearm.

Diese Beschleunigungen und Verzögerungen sind. selbstverständlich in erster Linie auch von der Kadenz der Waffe bzw. von der Drehzahl des Waffensimulators abhängig. Soweit aber Beschleunigung und Verzögerung von der Form der Nockenscheiben 19 und 20 abhängig sind, können sie durch die Formgebung der Nockenscheiben 19 und 20 gesteuert werden.These are accelerations and decelerations. Of course, primarily dependent on the cadence of the weapon or the speed of the weapon simulator. However, as far as acceleration and deceleration depend on the shape of the cam disks 19 and 20, they can be controlled by the shape of the cam disks 19 and 20.
