Description
Die Erfindung betrifft eine Kühleinrichtung für Revolvertrommeln von
Revolverkanonen,
nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a cooling device for revolver drums from
Revolver cannons,
according to the preamble of
Bei Revolverkanonen wie beispielsweise aus einer Druckschrift OC 2059 e 94 der Firma Oerlikon-Contraves, Zürich, bekannt, wird im allgemeinen die beim Schiessen erwärmte Revolvertrommel durch die Umgebungsluft gekühlt. Bei längeren Feuerstössen und schneller Geschossfolge ist diese Kühlungsart jedoch ungenügend, da sich der Bereich der Trommel, in welchem das Geschoss im Patronenlager geführt wird, sehr stark erhitzen kann. Dadurch kann es bei Weiterleitung der Wärme in denjenigen Bereich der Trommel, in dem die Hülse im Patronenlager geführt wird zu einem kritischen Zustand kommen, so dass Sicherheits- und Zuverlässigkeitsprobleme wie z.B. Überdruckschüsse, Zündversager, Cook OFF usw. auftreten können. In the case of revolver cannons, for example from a publication OC 2059 e 94 from the company Oerlikon-Contraves, Zurich, the revolver drum heated during firing is generally cooled by the ambient air. In the case of longer bursts of fire and rapid projectile order, this type of cooling is insufficient, however, since the area of the drum in which the projectile is carried in the cartridge chamber can heat up considerably. This can result in a critical condition when the heat is transferred to the area of the drum in which the sleeve is guided in the cartridge chamber, so that safety and reliability problems such as excess pressure shots, ignition failure, Cook OFF, etc. can occur.
Mit der deutschen Patentschrift DE-PS 31 45 764 ist eine Kühleinrichtung für Waffen rohre von Feuerwaffen, insbesondere automatischen Feuerwaffen und Hochleistungsmaschinenkanonen bekannt geworden. Bei derartigen Hochleistungsfeuerwaffen, die hochgezüchtete Munition verfeuern, ist der hohe Waffenrohrverschleiss darauf zurückzuführen, dass die Oberflächenwärme nicht genügend schnell abgeführt wird. Die schnell aufeinanderfolgende Wärmebeaufschlagung beim Feuerstoss verursacht Oberflächenspannungen und Werkstoffumwandlungen. Durch das Flattern der Geschosse im Waffenrohr werden die Züge verformt, und es kommt zur Abtragung von Material durch das Führungsband der Geschosse. Um die Lebensdauer der Waffenrohre zu erhöhen wird mit vorstehend zitierter Patentschrift vorgeschlagen, im Bereich des axial an eine Trommel angrenzenden Endteiles des Waffenrohres in der Trommel radial nach aussen zwischen den einzelnen Patronenlagern ausgerichtete Kühlkanäle vorzusehen, die mit einem in der Trommelachse verlaufenden Hauptkanal für die Kühlmittelzuführung verbunden sind. Die Kühlkanäle sind mit parallel zur Trommelachse verlaufenden Düsen verbunden, die in die dem Waffenrohr zugewandte Stirnseite der Trommel einmünden und im gleichen Abstand zur Trommellängsachse wie die Mittellängsachsen der Patronenlager angeordnet sind. In den Kühlkanälen sind Absperrorgane für die Düsen vorgesehen, die im Falle des Beschusses jeweils diejenige Düse kurzzeitig freigeben, die sich im Bereich der Rohröffnung befindet. Die Absperrorgane sind z.B. Schieber, die mittels an einer Steuerkurve bei Drehbewegung der Trommel entlanggleitenden Steuerstücken verschoben werden können. Das Kühlmittel gelangt durch die Düsen direkt auf die Innenwandung des Waffen rohres im rückwärtigen Teil. Dabei sind die Düsen nur jeweils für den Zeitraum des Vorbeigleitens der Düsen im Waffenrohrrückteil geöffnet und die Kühlmittelzufuhr erfolgt nur dann, wenn geschossen wird.With the German patent DE-PS 31 45 764 , a cooling device for gun tubes of firearms, in particular automatic firearms and high-performance machine guns, has become known. In high-performance firearms of this type, which fire highly-developed ammunition, the high level of wear on the weapon barrel is due to the fact that the surface heat is not dissipated quickly enough. The rapid succession of heat during the burst of fire causes surface tensions and material conversions. When the bullets flap in the weapon barrel, the trains are deformed and material is removed by the bullet's guide band. In order to increase the service life of the weapon barrels, the patent cited above proposes to provide cooling channels in the region of the end part of the weapon barrel axially adjacent to a drum in the drum, radially outward, between the individual cartridge chambers, which have a main channel for the coolant supply running in the drum axis are connected. The cooling channels are connected to nozzles running parallel to the drum axis, which open into the end of the drum facing the weapon barrel and are arranged at the same distance from the longitudinal axis of the drum as the central longitudinal axes of the cartridge chamber. Shut-off devices for the nozzles are provided in the cooling channels, which in the event of bombardment briefly release the nozzle in the area of the pipe opening. The shut-off devices are, for example, slides which can be moved by means of control pieces sliding along a control cam when the drum rotates. The coolant passes through the nozzles directly onto the inner wall of the weapon barrel in the rear part. The nozzles are only open for the period when the nozzles slide past in the rear of the gun barrel and the coolant is only supplied when shooting.
Obwohl das Kühlmittel bei vorstehend beschriebener Kühleinrichtung für ein Waffenrohr durch die Trommel geführt wird, kann damit lediglich nur eine Kühlung im Bereich der Trommelstirnwand erreicht werden, so dass diese Einrichtung für die Beseitigung der eingangs genannten Probleme nicht geeignet ist. Although the coolant in the above-described cooling device for one Gun barrel is passed through the drum, can only be a cooling in Area of the drum front wall can be reached, so that this device for the Eliminating the problems mentioned above is not suitable.
Die US-A-2,801,575 (siehe den Oberbegriff des Anspruchs 1) beschreibt eine Revolvertrommel einer Feuerwaffe mit einer Kühleinrichtung; in Umfangsrichtung folgen sich abwechselnd zur Trommelachse parallele und miteinander an ihren Enden und über ihre Länge an einer Vielzahl von Stellen verbundene Kühlklanäle, die sich über die Länge der Geschossführung der Patronenlager erstrecken, so dass jedes Patronenlager zwischen zwei Kühlkanälen liegt und von beiden eine Kühlwirkung erfährt. Umgekehrt ist auch jeder Kühlkanal zwischen zwei Patronenlagern angeordnet und muss somit zur Kühlung von zwei Patronenlagern beitragen, so dass eine genügende Kühlwirkung pro Patronenlager nicht gewährleistet ist, obwohl die Konstruktion infolge der Vielzahl der Verbindungskanäle verhältnismässig aufwendig ist. US-A-2,801,575 (see the preamble of claim 1) describes a revolver barrel of a firearm with a cooling device; In the circumferential direction, alternating cooling channels follow in parallel to the drum axis and are connected to one another at their ends and along their length at a multiplicity of locations, which extend over the length of the bullet guide of the cartridge chamber, so that each cartridge chamber lies between two cooling channels and experiences a cooling effect from both . Conversely, each cooling channel is arranged between two cartridge chambers and must therefore contribute to the cooling of two cartridge chambers, so that a sufficient cooling effect per cartridge chamber is not guaranteed, although the construction is relatively complex due to the large number of connecting channels.
Die Aufgabe der Erfindung wird somit darin gesehen, eine Revolvertrommel einer Revolverkanone mit einer Kühleinrichtung für die Revolvertrommel zu schaffen, welche die vorstehend beschriebenen Nachteile nicht aufweistThe object of the invention is thus seen in a revolver barrel of a revolver cannon with a cooling device for the revolver drum to create the above Disadvantages described does not have
Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1
gelöst. Hierbei sind, wie bei soeben genannten US-Patentschrift jedem Patronenlager zwei
Kühlkanäle zugeordnet, wobei aber, im Gegensatz zur Einrichtung gemäss dieser Patentschrift,
beide Kühlkanäle nur für die Kühlung eines einzigen Patronenlagers zuständig sind. This object is achieved by the features of the characterizing part of
Im Bereich der einen Stirnseite der Revolvertrommel steht jeweils der erste von zwei einem Patronenlager zugeordneten Kühlkanälen über erste tangentiale Verbindungsrohre und die radialen Eingangskanäle mit dem in der Trommelachse vorgesehenen Zuflusskanal in Verbindung. Jeweils der zweite von zwei einem Patronenlager zugeordneten Kühlkanälen ist ebenfalls im Bereich der einen Stirnseite der Revolvertrommel über zweite tangentiale Verbindungsrohre und radiale, parallel zu den Eingangskanälen verlaufende Ausgangskanäle mit einem in der Trommelachse vorgesehenem Abflusskanal verbunden.In the area of one end of the revolver drum stands the first of two cooling channels assigned to a cartridge chamber first tangential connecting pipes and the radial input channels with the one in the Inflow channel provided in the drum axis in connection. The second of each two cooling channels assigned to a cartridge chamber is also in the area of an end face of the revolver drum via second tangential connecting pipes and radial output channels running parallel to the input channels with an in connected to the drain axis provided drain channel.
Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, dass das
Kühlmittel nicht nacheinander durch alle Kühlkanäle der Revolvertrommel geführt
wird, sondern dass jedem
Patronenlager ein eigener Kühlkreislauf zugeordnet ist, womit eine wirksame, die
Wärme schnell abführende Kühlung erzielt wird. Ein weiterer Vorteil ist darin zu
sehen, dass ein wesentlicher Teil der Wärme im am stärksten erhitzten Bereich, in
welchem das Geschoss im Patronenlager geführt wird, schnell abgeführt wird.
Dadurch kann sich der Bereich der Revolvertrommel, in dem die Hülse im
Patronenlager geführt wird, nicht mehr so stark erwärmen.
Mit diesen Massnahmen werden die Beeinträchtigung der Kanonenfunktionen und
festigkeitsmässige Probleme vermieden sowie der Spannungsverlauf in der Trommel
verbessert.
Weitere Vorteile sind in den geringen Herstellungs- und Logistikkosten sowie im
kleinen Änderungsaufwand an bestehenden Kanonen zu sehen. The advantages achieved by the invention are, in particular, that the coolant is not passed through all the cooling channels of the revolver drum one after the other, but that each cartridge chamber is assigned its own cooling circuit, with the result that effective, rapidly dissipating cooling is achieved. Another advantage can be seen in the fact that a substantial part of the heat is quickly dissipated in the most heated area, in which the projectile is guided in the cartridge chamber. As a result, the area of the revolver drum in which the sleeve is guided in the cartridge chamber can no longer heat up as much.
With these measures, the impairment of the cannon functions and strength problems are avoided and the tension curve in the drum is improved.
Further advantages can be seen in the low manufacturing and logistics costs as well as in the small change effort for existing cannons.
