Description

Die Erfindung betrifft eine Mündungsbremse für eine Rohrwaffe mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a muzzle brake for a barrel weapon with the features of the preamble of claim 1.

Eine derartige Mündungsbremse ist aus der GB-A- 168 156 bekannt.Such a muzzle brake is known from GB-A-168 156.

Mit einer solchen Mündungsbremse kann die Größe der wirkenden Rücklaufenergie und der Rücklauf des Rohrs vermindert werden, wodurch beispielsweise auch die Feuergeschwindigkeit gesteigert werden kann. Durch mit der Mündungsbremse verbundene Gasaustrittsöffnungen, die in einer parallel zur Erdoberfläche verlaufenden Ebene diametral einander gegenüberliegend angeordnet sind, kann verhindert werden, daß nach dem Schuß austretende Gase auf die Erdoberfläche aufprallen und sichtbehindernde Staubwolken aufwirbeln.With such a muzzle brake, the size of the effective return energy and the return of the pipe can be reduced, which can also increase the rate of fire, for example. Gas outlet openings connected to the muzzle brake, which are arranged diametrically opposite one another in a plane running parallel to the surface of the earth, can prevent gases escaping after the shot from striking the earth's surface and whirling up dust clouds obstructing vision.

Bei dieser bekannten Mündungsbremse, die aus einem auf das Waffenrohr aufschiebbaren Mantelrohr und einem darin verschraubten hülsenartigen Rohrstück mit dem wiederum ein Kragen verschraubt ist, besteht, weist das hülsenartige Rohrstück einen größeren Innendurchmesser als die Waffe aus und es besitzt nur in einer Ebene rings um den Umfang verlaufende Bohrungen für den Gasdurchtritt. Die Gasaustrittsöffnungen befinden sich im Mantelrohr in nach hinten gerichteten rohrförmigen Ansätzen, durch die ggfs. mit Hilfe zusätzlicher Krümmer zur Rückstoßveränderung die Gase unter unterschiedlichem Winkel nach hinten austreten sollen. Diese Vorrichtung ist einerseits für den Einsatz von Treibspiegelgeschossen ungeeignet. Andererseits ist auch ein widerstandsarmes Abströmen der Treibgase wegen des geringen Querschnitts für den Gasdruchtritt und wegen in die Ansätze hineinragender Schultern des Kragens nicht möglich.In this known muzzle brake, which consists of a sleeve tube that can be pushed onto the weapon barrel and a sleeve-like tube piece screwed into it, with which in turn a collar is screwed, the sleeve-like tube piece has a larger inner diameter than the weapon and it has only one plane around it Circumferential holes for gas passage. The gas outlet openings are located in the tubular casing in rear-facing tubular lugs, through which the gases are to exit at different angles, if necessary, with the aid of additional bends for changing the recoil. On the one hand, this device is unsuitable for the use of sabot projectiles. On the other hand, a low-resistance outflow of the propellant gases is also not possible because of the small cross section for the gas passage and because of the shoulders of the collar protruding into the approaches.

Eine Mündungsbremse mit einander etwa diametral gegenüberliegenden Austrittsöffnungen in einem Mantelrohr zeigt die US-A- 3,858,481. Bei dieser Vorrichtung sind die Gäsdurchtrittsbohrungen unmittelbar in das Waffenrohr eingearbeitet und liegen in parallelen Reihen nebeneinander. Um das Waffenrohr ist das Mantelrohr so angeordnet, daß die aus den Bohrungen austietenden Gase zunächst parallel zum Waffenrohr geleitet werden und dann aus den verhältnismäßig engen schlitzartigen Gasaustrittsöffnungen im Mantelrohr austreten. Bei einer solchen Vorrichtung ist ein Auswechseln der Mündungsbremse nicht möglich und es ist eine Sichtbehinderung nicht zu vermeiden, da die Schlitze im Mantelrohr sich in unmittelbarer Nähe des Waffenrohres befinden. Weiterhin ist ein ungebremstes freies Abströmen der Gase,durch das Verschleißminderung und Erhöhung der Lebensdauer erreichbar ist, nicht möglich.US-A-3,858,481 shows a muzzle brake with approximately diametrically opposite outlet openings in a casing tube. In this device, the gas passage bores are machined directly into the weapon barrel and lie side by side in parallel rows. The jacket tube is arranged around the weapon barrel in such a way that the gases emerging from the bores are first passed parallel to the gun barrel and then emerge from the relatively narrow slot-like gas outlet openings in the jacket tube. With such a device, it is not possible to replace the muzzle brake and it is impossible to avoid a visual obstruction, since the slots in the casing tube are in the immediate vicinity of the weapon barrel. Furthermore, an unrestrained free flow of gases, which can reduce wear and increase the service life, is not possible.

Aus der DE-C-169 838 ist eine Rohrbremse bekannt, bei der im vorderen Endbereich des Waffenrohres Widerstandsflächen in eingedrehten parallelen oder schraubenlinigen Ringnuten gebildet sind und durch die Wand des Rohres gegen diese Widerstandsflächen gerichtete Kanäle nach außen führen, um den Widerstand der Pulvergase allmählich wachsend wirken zu lassen. Bei dieser ebenfalls nicht austauschbaren Mündungsbremse treten die Gase rings um den Rohrdurchmesser herum aus. Eine Sichtbehinderung und Behinderung durch Pulvergase ist somit nicht zu vermeiden.From DE-C-169 838 a tube brake is known in which resistance surfaces are formed in screwed parallel or helical ring grooves in the front end region of the weapon barrel and lead through the wall of the tube against these resistance surfaces to the outside to gradually reduce the resistance of the powder gases to have a growing effect. With this muzzle brake, which is also not exchangeable, the gases escape around the pipe diameter. Visibility and obstruction by powder gases cannot be avoided.

Infolge der Nuten an der Innenwand des Rohres können Geschosse mit Führungsband hier nicht verwendet werden. Die Vorrichtung ist materialaufwendig und daher sehr schwer.Due to the grooves on the inner wall of the tube, bullets with a guide band cannot be used here. The device is expensive and therefore very heavy.

Eine ähnliche Anordnung einer auf das Rohrende aufschraubbaren Mündungsbremse zeigt die GB-A- 125 141. Sie weist somit im wesentlichen die gleichen Nachteile wie die Vorrichtung nach der DE-C- 169 838 auf, verursacht insbesondere eine starke Belästigung durch Gase und aufgewirbelten Staub.A similar arrangement of a muzzle brake which can be screwed onto the pipe end is shown in GB-A-125 141. It thus has essentially the same disadvantages as the device according to DE-C-169 838, in particular causing severe annoyance by gases and whirled up dust.

Aufgabe der Erfindung ist es somit eine Mündungsbremse anzugeben, bei der die Sichtbehinderung durch Rauchgase wesentlich verringert ist und nur eine geringere Zeitdauer anhält, so daß beidem Abfeuern des Geschosses der Weg des Geschosses und sein Zielaufschlag mit optischen Mitteln beobachtbar ist. Dabei soll die Mündungsbremse auswechselbar, einfach herstellbar und verschleißunanfällig sein und sie soll insbesondere für großkalibrige Waffen und für den Einsatz von Treibspiegelgeschossen geeignet sein. Eine nachteilige Beeinflussung der Visiermittel durch Rauchgase sowie des Bedingungspersonals durch Staubaufwirbelung o. dgl. soll vermieden sein.The object of the invention is therefore to provide a muzzle brake in which the visual impairment due to flue gases is significantly reduced and only lasts for a shorter period of time, so that when the projectile is fired, the path of the projectile and its target impact can be observed by optical means. The muzzle brake should be replaceable, easy to manufacture and not susceptible to wear and should be particularly suitable for large-caliber weapons and for the use of sabot projectiles. A disadvantageous influence of the sighting means by smoke gases as well as of the condition personnel by dust whirling up or the like should be avoided.

Die zur Lösung der gestellten Aufgabe notwendigen wesentlichen Merkmale der Erfindung sind im kennzeichnenden Teil des Patentanspruchs 1 genannt. Die Unteransprüche nennen Ausführungsarten der Erfindung.The essential features of the invention necessary to achieve the object are mentioned in the characterizing part of patent claim 1. The subclaims list embodiments of the invention.

Die Erfindung wird nachfolgend unter Bezug auf die Zeichnung erläutert. Dabei zeigt:

  • Fig. 1: eine Seitenansicht (teilweise in Schnittdarstellung) der Mündungsbremse;
  • Fig. 2: eine Ansicht der Mündungsbremse mit Blickrichtung A gem. Fig. 1;
  • Fig. 3: einen Querschnitt durch die Mündungsbremse entlang der Linie 3 - 3 von Fig. 1 ;
  • Fig. 4: eine vergrößerte Detaildarstellung des Bereichs X aus Fig. 1;
  • Fig. 5: eine vergrößerte Detaildarstellung eines weiteren Ausführungsbeispiels der Erfindung mit winklig zur Rohrlängsachse verlaufenden Bohrungen.
The invention is explained below with reference to the drawing. It shows:
  • Fig. 1: a side view (partially in section) of the muzzle brake;
  • 2: a view of the muzzle brake with viewing direction A acc. Fig. 1;
  • 3 shows a cross section through the muzzle brake along the line 3 - 3 of FIG. 1;
  • FIG. 4: an enlarged detailed representation of area X from FIG. 1;
  • 5: an enlarged detailed illustration of a further exemplary embodiment of the invention with bores running at an angle to the longitudinal axis of the tube.

Fig. 1 zeigt teilweise in Schnittdarstellung die Seitenansicht der Mündungsbremse 10, die ein Rohrstück 22 (Fig. 3) umfaßt, dessen Innendurchmesser kalibergleich ausgebildet ist. In das Rohrstücks 22 sind Bohrungen 14 eingebracht, die in mehreren hintereinander parallel und senkrecht zur Längsachse des Waffenrohrs verlaufenden Ebenen 15 angeordnet sind. Die Bohrungen 14 sind in jeder Ebene 15 gleichmäßig auf dem Umfang des Rohrstücks 22 beabstandet angeordnet und erstrecken sich vorzugsweise in Radialrichtung. Durch die kalibergleiche Ausgestaltung des Innendurchmessers des Rohrstücks 22 wird sichergestellt, daß beim Abfeuern von Treibkäfiggeschossen die Ablösung des Treibkäfigs erst nach dem Austreten des Geschosses aus der Mündung der Mündungsbremse eingeleitet werden kann.Fig. 1 shows a partial sectional view of the side view of the muzzle brake 10, which comprises a pipe section 22 (Fig. 3), the inner diameter of which is of the same caliber. Bores 14 are made in the tube piece 22 and are arranged in a plurality of planes 15 running parallel and perpendicular to the longitudinal axis of the weapon barrel. The bores 14 are uniform in each plane 15 on the circumference of the pipe section 22 spaced apart and preferably extend in the radial direction. The design of the inner diameter of the pipe section 22 of the same caliber ensures that when sabot projectiles are fired, the sabot detachment can only be initiated after the projectile has emerged from the muzzle of the muzzle brake.

In einem weiteren Ausführungsbeispiel der Erfindung (Fig.5) sind Bohrungen 14' in einem Winkel a- zur Rohrlängsachse verlaufend in hintereinanderliegenden Kegelmantelflächen angeordnet. Durch die Schräganordnung der Bohrungen 14' kann im Bedarfsfall die Wirkung der Mündungsbremse vergrößert werden.In a further exemplary embodiment of the invention (FIG. 5), bores 14 'are arranged at an angle α to the longitudinal axis of the tube in conical surface areas lying one behind the other. Through the inclined arrangement of the bores 14 ', the effect of the muzzle brake can be increased if necessary.

Die Bohrungen 14 bzw. 14' sind in benachbarten Ebenen 15 bzw. in benachbarten Kegelmantelflächen winkelmäßig zueinander derart versetzt angeordnet, daß sie "auf Lücke" zueinander liegen. Dadurch wird erreicht, daß auf der Innenmantelfläche der Mündungsbremse 10 eine gleichmäßige Verteilung zwischen den Querschnittsflächen der Bohrungen 14, 14' und der Innenrohrmantelfläche gegeben ist. Das Verhältnis der von den Bohrungen eingenommenen Fläche zur gesamten Innenmantelfläche sollte zweckmäßig nicht größer als etwa 0,5 sein. Auf diese Weise wird die Lebensdauer der Mündungsbremse gesteigert, da ein sehr gleichmäßiger Verschleiß stattfindet.The bores 14 and 14 'are angularly offset from one another in adjacent planes 15 or in adjacent conical lateral surfaces in such a way that they lie "at a gap" to one another. It is thereby achieved that on the inner lateral surface of the muzzle brake 10 there is a uniform distribution between the cross-sectional areas of the bores 14, 14 'and the inner tubular lateral surface. The ratio of the area occupied by the bores to the total inner surface area should expediently not be greater than about 0.5. In this way, the life of the muzzle brake is increased because wear is very even.

Vorzugsweise sind die Querschnittsflächen der Bohrungen 14, 14' kreisförmig ausgebildet; es sind jedoch auch andere Querschnittsformen möglich, die jedoch schwieriger herzustellen sind. Koplanar zu den Ebenen 15 sind in die Außenmantelfläche 40 des Rohrstücks 22 kreisringförmig ausgebildete Nuten eingebracht, in die die Austrittsöffnungen der jeweils in einer Ebene 15 liegenden Bohrungen 14 münden. Bei dem Ausführungsbeispiel der Erfindung, bei dem die Bohrungen 14,14' einen Winkel mit einer auf der Rohrlängsachse senkrecht stehenden Ebene bilden, sind die Nuten 13 in gleichmäßig beabstandeten,parallel zueinander und senkrecht zur Rohrlängsachse verlaufendenen Ehenen derart angeordnet, daß sie ebenfalls die Austrittsöffnungen der Bohrungen 14' miteinander verbinden. Die Nuten 13 bilden solchermaßen um das Rohrstück 22 herumlaufende Kanäle, die die durch die Bohrungen 14 bzw. 14' aus dem Innern austretenden Rauchgase sehr effektiv abführen.The cross-sectional areas of the bores 14, 14 ′ are preferably circular; however, other cross-sectional shapes are possible, but they are more difficult to manufacture. Coplanar to the planes 15, annular grooves are made in the outer circumferential surface 40 of the pipe section 22, into which the outlet openings of the bores 14 each lying in a plane 15 open. In the embodiment of the invention, in which the bores 14, 14 'form an angle with a plane perpendicular to the longitudinal axis of the tube, the grooves 13 are arranged in evenly spaced marriages running parallel to one another and perpendicular to the longitudinal axis of the tube in such a way that they also form the outlet openings connect the holes 14 'together. The grooves 13 thus form channels running around the pipe section 22, which very effectively discharge the flue gases emerging from the interior through the bores 14 and 14 '.

In einem weiteren Ausführungsbeispiel der Erfindung kann auch eine spiralförmig verlaufende Nut vorgesehen sein, die sich um das Rohrstück 22 der Mündungsbremse 10 herumwindet und alle Austrittsöffnungen aller Bohrungen 14, 14' miteinander verbindet.In a further exemplary embodiment of the invention, a spiral-shaped groove can also be provided, which winds around the pipe section 22 of the muzzle brake 10 and connects all outlet openings of all bores 14, 14 'to one another.

Das Rohrstück 22 der Mündungsbremse 10 ist koaxial von einem Mantelrohr 12 umgeben, das gasdicht auf den zwischen den Nuten 13 vorhandenen Stegen aufliegt und das diametral gegenüberliegende Fortsätze 21 mit dort angeordneten Austrittsöffnungen 30 umfaßt. In an sich bekannter Weise sind diese Austrittsöffnungen in einer parallel zur Erdoberfläche liegenden Ebene angeordnet, um sicherzustellen, daß austretende Gase nur seitwärts austreten können und nicht zur Aufwirbelung von die Sicht behindernden Staubwolken beitragen.The pipe section 22 of the muzzle brake 10 is coaxially surrounded by a casing tube 12 which rests gas-tight on the webs present between the grooves 13 and which comprises diametrically opposite extensions 21 with outlet openings 30 arranged there. In a manner known per se, these outlet openings are arranged in a plane lying parallel to the surface of the earth, in order to ensure that escaping gases can only escape laterally and do not contribute to the raising of dust clouds obstructing the view.

Die Mündungsbremse ist zweckmäßig auf das Waffenrohr aufschraubbar ausgebildet. Auf diese Weise ist sie leicht auswechselbar und kann im Bedarfsfalle gegen andere Mündungsbremsen ausgewechselt werden, ohne einen Austausch des kompletten Waffenrohrs vornehmen zu müssen.The muzzle brake is expediently designed to be screwed onto the weapon barrel. In this way it is easy to replace and can be exchanged for other muzzle brakes if necessary without having to replace the entire barrel.

Durch die neuartige Anordnung von Bohrungen 14, 14' und umlaufenden Nuten 13 wird eine besonders gute Wirkung der Mündungsbremse erreicht. Die beim Schuß entstehenden Rauchgase werden wirksam abgeführt, mit der Folge, daß eine unvermeidliche Sichtbehinderung durch diese Rauchgase im Vergleich zu herkömmlichen Lösungen nur während einer vergleichsweise geringen Zeitdauer anhält. Dies bietet insbesondere den Vorteil, daß bei Abfeuern eines Geschosses der Weg des Geschosses und sein Zielaufschlag mit optischen Mitteln beobachtbar ist. Weiterhin ist es möglich, die Kadenz zu steigern, ohne daß die Zielgenauigkeit wegen mangelnder Beobachtungsmöglichkeit des Ziels infolge Rauchgasbehinderung leidet.A particularly good effect of the muzzle brake is achieved by the novel arrangement of bores 14, 14 'and circumferential grooves 13. The smoke gases generated during the shot are effectively removed, with the result that an unavoidable visual obstruction by these smoke gases only lasts for a comparatively short period of time compared to conventional solutions. This offers the particular advantage that when a projectile is fired, the path of the projectile and its target impact can be observed with optical means. Furthermore, it is possible to increase the cadence without the accuracy of the target suffering because of a lack of observation of the target due to smoke obstruction.
