Description

Die Erfindung betrifft eine Mündungsbremse für eine Rohrwaffe mit einem mit dem Seelenrohr fluchtenden,Bohrungen aufweisenden Rohrstück und diametral gegenüberliegend angeordneten Gasaustrittsöffnungen, die im wesentlichen senkrecht zur Rohrlängsachse verlaufen.The invention relates to a muzzle brake for a tube weapon with a tube piece aligned with the core tube and having bores and diametrically opposed gas outlet openings which are essentially perpendicular to the longitudinal axis of the tube.

Eine derartige Mündungsbremse ist aus Militärtechnik 6/1974, Seite 250 bekannt.Such a muzzle brake is known from military technology 6/1974, page 250.

Die Wirkung einer Mündungsbremse besteht bekanntlich darin, den Wirkungsanteil der unmittelbar nach dem Geschoß aus der Mündung austretenden Treibladungsgase zu verringern, wodurch sich vielfältige Vorteile erreichen lassen. So 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 weiterhin verhindert werden, daß nach dem Schuß austretende Gase auf die Erdoberfläche aufprallen und sichtbehindernde Staubwolken aufwirbeln. Weiterhin kann mit der Mündungsbremse die Rauchgasverteilung der aus der Mündung austretenden Pulvergase beeinflußt werden.As is known, the effect of a muzzle brake consists in reducing the proportion of the propellant gas escaping from the muzzle immediately after the projectile, as a result of which various advantages can be achieved. 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 furthermore prevent gases escaping after the shot from hitting the earth's surface and whirling up dust clouds obstructing vision. Furthermore, the flue gas distribution of the powder gases emerging from the mouth can be influenced with the muzzle brake.

Der Erfindung liegt die Aufgabe zugrunde, eine neuartige, insbesondere für großkalibrige Waffen geeignete Mündungsbremse anzugeben, die einfach herstellbar ist und mit der insbesondere auch Treibspiegelgeschosse verschießbar sein sollen. Weiter soll mit der neuartigen Mündungsbremse die Rauchgasverteilung verbessert werden, um eine nachteiligige Beeinflussung der Visiermittel durch Rauchgase zu verhindern.The invention is based on the object of specifying a novel muzzle brake which is particularly suitable for large-caliber weapons and which is simple to manufacture and with which, in particular, sabot projectiles should also be able to be fired. The new muzzle brake is also intended to improve the flue gas distribution in order to prevent the sighting means being adversely affected by flue gases.

Diese Aufgabe wird durch die in Patentanspruch 1 angegebene Erfindung gelöst.This object is achieved by the invention specified in claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous refinements and developments of the invention emerge from the subclaims.

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

  • Fig. I: eine Seitenansicht (teilweise in Schnittdarstellung) der Mündungsbremse;
  • Fig. 2: eine Ansicht der Mündungsbremse mit Blickrichtung A gem. Fig. l;
  • 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:
  • I: a side view (partially in section) of the muzzle brake;
  • 2: a view of the muzzle brake with viewing direction A acc. Fig. L;
  • 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 Rohrstück 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 Rohrs 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 tubular piece 22 and are arranged in several planes 15 running one behind the other and parallel and perpendicular to the longitudinal axis of the weapon barrel. The bores 14 are evenly spaced on the circumference of the tube 22 in each plane 15 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 o(_ 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 o ( _) to the longitudinal axis of the pipe in conical surface areas one behind the other. If necessary, the effect of the muzzle brake can be increased by the oblique arrangement of the bores 14'.

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. This ensures that there is a uniform distribution on the inner surface of the muzzle brake 10 between the cross-sectional areas of the bores 14, 14 'and the inner tube surface. The ratio of the area occupied by the holes to the total inner surface area should advantageously 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 Rohrs 24 kreisringförmig ausgebildete Nuten 13 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 α mit einer auf der Rohrlängsachse senkrecht stehenden Ebene bilden, sind die Nuten 13 in gleichmäßig beabstandeten,parallel zueinander und senkrecht zur Rohrlängsachse verlaufendenen Ebenen derart angeordnet, daß sie ebenfalls die Austrittsöffnungen der Bohrungen 14' miteinander verbinden. Die Nuten 13 bilden solchermaßen um das Rohr 24 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 13 are formed in the outer circumferential surface 40 of the tube 24, 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 α with a plane perpendicular to the longitudinal axis of the tube, the grooves 13 are arranged in evenly spaced planes which run parallel to one another and perpendicular to the longitudinal axis of the tube in such a way that they also form the Connect the outlet openings of the bores 14 'to one another. The grooves 13 thus form channels running around the tube 24, which discharge the flue gases emerging from the interior through the bores 14 and 14 'very effectively.

In einem weiteren Ausführungsbeispiel der Erfindung kann auch eine spiralförmig verlaufende Nut vorgesehen sein, die sich um das Rohr 24 der Mündungsbremse 10 herumwindet und alle Austrittsöffnungen aller Bohrungen 14, 14' miteinander verbindet.In a further exemplary embodiment of the invention, a spiral groove can also be provided, which winds around the tube 24 of the muzzle brake 10 and connects all outlet openings of all bores 14, 14 'to one another.

Das Rohr 24 der Mündungsbremse 10 ist koaxial von einem Mantelrohr 12 umgeben, das gasdicht auf den zwischen den Nuten 13 vorhandenen Stegen aufliegt und das diametral gegen-. überliegende 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 tube 24 of the muzzle brake 10 is coaxially surrounded by a jacket tube 12 which rests gas-tight on the webs present between the grooves 13 and which is diametrically opposed. overlying projections 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 not to Whirl up dust clouds that obstruct 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 due to a lack of observation of the target due to smoke obstruction.
