Abstract
Description
Bei Waffen, welche in erster Linie in Trägern, wie Fahr- und Flugzeugen, eingebaut sind, gibt es oftmals Probleme mit dem Hülsenauswurf. Vor allem dann, wenn die Hülse beim Schießen in schwer zugängliche Auffangbehälter und in genau definierten Positionen geworfen werden sollen. Aufgrund von notwendigen Führungskanälen und Hülsenumlenkungen kann die Hülse auf dem Weg zu ihrer Endposition in ihrer Flugzeit bzw. Fluggeschwindigkeit stark abgebremst werden. Beim Schießen kommt es dann zu Störungen, welche durch die undefinierte Positionen der Hülsen oder durch ihr Liegenbleiben auf dem Weg zu ihrer Endposition hervorgerufen wird. Es entstehen Hülsenstaus oder aber die Hülsen sind nicht in der richtigen Abführposition im Munitionstransportsystem. Die Auswurfgeschwindigkeit ist stark abhängig vom Liderungscharakter der Patronen bzw. Hülsen nach dem Schuß im Patronenlager.at Weapons, which are primarily used in vehicles such as vehicles and aircraft, are installed, there are often problems with the sleeve ejection. Especially if the sleeve when shooting in hard-to-reach receptacle and to be thrown in well-defined positions. by virtue of of necessary guide channels and sleeve deflections can the sleeve on the way to their final position in their flight time or flight speed be braked strongly. When shooting, then it comes to interference, which through the undefined positions of the sleeves or by staying there on the way to their final position. It arises sleeve congestion or the sleeves are not in the correct laxative position in the ammunition transport system. The ejection speed is strong dependent the Liderungscharakter the cartridges or sleeves after the shot in the chamber.
Aus
der
Die Liderung wird bekanntlich stark beeinflußt vom Gasdruck der Patrone, dem Patronenlagerzustand, wie Reibung, Schmierung, Verschmutzung und Korrosion, von der Hülsenbeschaffenheit, wie beispielsweise die Härte der Hülse, die Beschichtung der Hülse oder aber das Toleranzfeld. Weitere Einflußgrößen sind der Zustand der Auswurfmechanik sowie die Verschmutzung durch Mündungsbremsen.The Lidding is known to be strongly influenced by the gas pressure of the cartridge, the cartridge bearing condition, such as friction, lubrication, pollution and Corrosion, from the shell texture, such as hardness the sleeve, the coating of the sleeve or the tolerance field. Further influencing factors are the state of the ejector mechanism as well the pollution by muzzle brakes.
Unter den bereits aufgeführten Situationen kann es auch bei der vorgenannten Verwendung eines Auswerfers zu Hülsenauswurfstörungen kommen. Die Hülsen erreichen nicht die sogenannte Fangposition im Munitionstransportsystem.Under the already listed Situations can also occur with the aforementioned use of an ejector come to sleeve ejection errors. The pods do not reach the so-called catch position in the ammunition transport system.
Hier stellt sich die Erfindung die Aufgabe, eine Möglichkeit für einen definierten Auswurf zu schaffen, um zu verhindern, dass es zu einem Hülsenstau etc. kommt.Here the invention provides the object, a possibility for a defined ejection to create, to prevent it becoming a sleeve jam etc. comes.
Der Erfindung liegt die Idee zugrunde, da die aufgezählten Beeinflussungsgrößen für die Liderung fertigungstechnischer als auch schießtechnischer Natur und daher mehr oder weniger unveränderbar sind, ein Patronenlager mit einem definierten Hülsenausziehwiderstand zu konzipieren. Dieser wird durch eine Mindestliderung geschaffen, die im Patronenlager integriert wird. Beim Auswurfvorgang wird die Entspannungsenergie genutzt und diese beim Lösen der Hülse entsprechend in eine Geschwindigkeit umgesetzt. Es wird eine Mindestspannung aufgebaut, was zur Folge hat, dass eine Vorspannung gesichert ist, so dass keine Geschwindigkeitsreduzierungen der Hülsen auftreten.Of the Invention is based on the idea, since the enumerated influencing variables for the production technology as well as shooting technical nature and therefore more or less unchangeable, a cartridge chamber with a defined sleeve pull-out resistance to design. This is created by a minimum amount of which is integrated in the chamber. The ejection process becomes the relaxation energy used and this while solving the Sleeve accordingly translated into a speed. It will be a minimum voltage constructed, which has the consequence that a bias is secured, so that no speed reduction of the sleeves occur.
Dazu
ist vorgesehen, wenigstens eine Rille in das Patronenlager im vorderen
Bereich einer Hülse
einer Patrone einzubringen. Eine Rille in einem Massenverschluss
ist zwar bereits aus der
Die Praxis hat gezeigt, dass eine Rille als ausreichend anzusehen ist, wobei auch mehr als eine möglich sind. Die einzelne Rille kann dabei über den gesamten Innenumfang (d. h., rundum) des Gehäuses des Patronenlagers oder aber nur in bestimmten Abschnitten des Innenumfangs eingebracht sein. Letzteres bietet sich unter anderem dann an, wenn mehr als eine Rille vorgesehen werden.The Practice has shown that a groove is sufficient, being also more than one possible are. The single groove can be over the entire inner circumference (ie, all around) of the housing the cartridge chamber or only in certain sections of the inner circumference be introduced. The latter offers, among other things, if more than one groove can be provided.
Anwendung findet die Lösung u. a. in hochkandenten Waffen mit einem gurtgliedlosen Munitionstransportsystem. Hierbei werden die abgeschossenen bzw. einem Trommelpatronenlager ausgeworfenen Hülsen über einen Puffer gedämpft in einem Kettensystem gefangen, genau positioniert und in eine Munitionsbox transportiert. Durch die definierte Auszugsspannung wird der sonst bekannte Fehler, der bei derartigen Systemen auftritt vermieden. Es wird verhindert, dass die Hülse auf ihrem Weg zur Fangposition abgebremst bzw. nicht mit einer Mindestgeschwindigkeit ausgeworfen wird, da in solchen Fällen das Munitionstransportsystem, über die Waffe gesteuert, beim nachfolgenden Schuss schon weiter dreht, bevor die Hülse ihre Sollposition erreicht hat.application finds the solution u. a. in high-firearm weapons with a beltless ammunition transport system. Here are the shot or a drum cartridge bearing ejected pods over one Buffer damped trapped in a chain system, accurately positioned and placed in a munitions box transported. By the defined pull-out voltage is the otherwise Known error that occurs in such systems avoided. It prevents the sleeve slowed down on their way to the catch position or not with a minimum speed is ejected because in such cases the ammunition transport system over which Weapon controlled, the next shot already rotates before the sleeve has reached its target position.
