Description

BESCHREIBUNG DESCRIPTION
Artillerie- oder Mörser-SprenggeschossArtillery or mortar explosive projectile
Die Erfindung betrifft ein Artillerie- oder Mörser- Sprenggeschoss, welches für die Detonation unter Wasser ausgelegt ist.The invention relates to an artillery or mortar explosive projectile, which is designed for detonation under water.
Derzeit werden so genannte Wasserbomben abgesetzt, um insbesondere Unterseeboote unschädlich zu machen. Um eine hohe Sprengkraft auch bei großen Wassertiefen erreichen zu können, wird als Sprengstoff häufig Torpex (d.h. eine Mischung aus Hexogen, Trinitrotoluol und Aluminiumpulver) verwendet.Currently, so-called water bombs are sold, in particular to make submarines harmless. Torpex (i.e., a mixture of hexogen, trinitrotoluene, and aluminum powder) is often used as the explosive to achieve high explosive power even at high water depths.
Die Verbringung der Wasserbomben in das entsprechende Zielgebiet erfolgt üblicherweise durch Abrollen der Bombe vom Heck eines Schiffes, durch Wasserbombenwerfern, welche die Wasserbomben vom Schiff aus bis zu 6500 m weit werfen können, oder durch Abwerfen von Flugzeugen oder Hubschraubern.Shipments of depth charges to the appropriate target area are usually made by unrolling the bomb from the stern of a ship, by water bomb throwers, which can launch the depth charges from the ship up to 6500 m, or by dropping planes or helicopters.
Nachteilig ist bei dem Abwerfen der Wasserbomben in dem Zielgebiet mittels eines Flugzeuges oder Hubschraubers unter anderem, dass das Verbringen der Bomben in das Zielgebiet relativ kostenaufwendig und nur bei entsprechend ausreichend guten Wetterverhältnissen möglich ist. Außerdem ist bei einer gegnerischen Luftüberlegenheit im Zielgebiet das Absetzen von Wasserbomben mit großer Gefahr für das jeweilige Luftfahrzeug und seine Besatzung verbunden.A disadvantage of the dropping of the depth charges in the target area by means of an aircraft or helicopter, inter alia, that the transfer of the bombs in the target area is relatively expensive and only with sufficiently good weather conditions possible. In addition, with an enemy air superiority in the target area, the launching of depth charges is associated with great danger to the respective aircraft and its crew.
Bei einem Einsetzen der Wasserbomben mit Hilfe von Schiffen müssen sich die Schiffe in den Bereich begeben, in dem U-Boote geortet wurden, so dass sie unter Umständen von den dort befindlichen U-Booten ebenfalls geortet und bekämpft werden.When using the depth charges with the help of ships, the ships must go to the area where submarines have been located so that they may also be located and fought by the submarines located there.
Der Erfindung liegt die Aufgabe zugrunde, eine Variante anzugeben, die auf einfache und kostengünstige Weise auch bei schlechten Wetterverhältnissen in ein Zielgebiet verbracht werden kann, ohne dass hierzu ein Luftfahrzeug oder ein Schiff erforderlich ist. - -The invention has for its object to provide a variant that can be spent in a simple and cost-effective manner even in bad weather conditions in a target area, without the need for an aircraft or a ship is required. - -
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
Die Erfindung beruht im Wesentlichen auf dem Gedanken, ein Artillerie- oder Mörserge- schoss bzw. Sprenggeschoss einzusetzen und dieses mittels eines großkalibrigen Geschützes, beispielsweise einer Haubitze, in das Zielgebiet zu verbringen. Durch eine derartige Maßnahme ist es möglich, ein Unterseeboot oder dergleichen (beispielsweise eine Seemine) von einem Schiff aus oder gegebenenfalls auch vom Land aus über eine Distanz > 30 km Entfernung zum Zielgebiet abwehren zu können. Das Geschoss trifft auf die Wasseroberfläche auf und sinkt tiefer, bis die über einen SpezialZünder eingestellte Tiefe erreicht ist. Bei dem Zünder des Geschosses kann es sich um einen hydrostatischen Druckzünder handeln, der beim Erreichen der eingestellten Wassertiefe anspricht. Je nach Anwendungsfall sind aber auch andere Zünder denkbar (z.B. Fernzünder, die aufgrund des magnetischen, akustischen oder hydrodynamischen Feldes des Zieles wirksam werden, oder Verzögerungszünder, die nach Ablauf einer eingestellten Zeit nach Eintauchen der Wasserbombe in das Wasser ansprechen), die zur Anwendung kommen.Essentially, the invention is based on the idea of using an artillery or mortar projectile or explosive projectile and transferring it to the target area by means of a large-caliber gun, for example a howitzer. By such a measure, it is possible to fend off a submarine or the like (for example, a sea mine) from a ship or, if necessary, also from land over a distance> 30 km distance to the target area. The bullet strikes the surface of the water and sinks deeper until the depth set by a special detonator is reached. The detonator of the projectile may be a hydrostatic pressure fuze, which responds when the set water depth is reached. Depending on the application, however, other detonators are conceivable (eg remote detonators, which become effective due to the magnetic, acoustic or hydrodynamic field of the target, or delay detonators, which respond after a set time after immersion of the water bomb in the water), which are used ,
Im Unterschied zu Geschosse für den Landeinsatz, bei denen auf eine besondere Verteilung der Splitter ankommt, um ein entsprechendes Ziel effektiv bekämpfen zu können, muss das Geschoss für den Unterwassereinsatz eine andere Auslegung erfahren. Unter Wasser sind Splitter auf wesentlich geringere Reichweite effektiv, so dass durch das Geschoss ähnlich wie eine Wasserbombe eine ausreichend große Druckwelle erzeugt werden muss. Daher ist neben dem Zünder und der Geschosshülle eine Anpassung der Sprengstoffart vorzunehmen. Der Sprengstoff kann dabei dem der Wasserbomben ähneln.Unlike missiles for land use, where a particular distribution of splinters is important in order to be able to effectively combat such a target, the missile must be interpreted differently for underwater use. Underwater splinters are effective at a much lower range, so that a sufficiently large pressure wave must be generated by the projectile similar to a water bomb. Therefore, in addition to the detonator and the projectile casing to make an adjustment of Explosengstoffart. The explosive can resemble that of the depth charges.
Damit das Geschoss möglichst viel Sprengstoff enthält, um eine ausreichend hohe Sprengkraft zu entfalten, hat es sich als zweckmäßig erwiesen, das erfindungsgemäße wie eine Wasserbombe wirkende Geschoss als drallstabilisiertes Geschoss mit einem Kaliber > 155 mm auszubilden.In order for the projectile to contain as much explosive as possible in order to develop a sufficiently high explosive force, it has proved expedient to design the projectile acting as a water bomb as a spin-stabilized projectile with a caliber> 155 mm.
Die Verwendung eines Artillerie- oder Mörsergeschoss weist überdies gegenüber herkömmlichen Wasserbomben den Vorteil auf, dass das Geschoss mit relativ hoher Geschwindigkeit in das Wasser des Zielgebietes eindringt und wesentlich schneller die vorgegebene Wassertiefe erreicht, bei der eine Zündung des Geschosses erfolgt. Geschaf- fen wird eine Lösung, die auf einfache und kostengünstige Weise auch bei schlechten Wetterverhältnissen anwendbar ist.The use of an artillery or mortar shell also has the advantage over conventional water bombs that the projectile penetrates at relatively high speed into the water of the target area and reaches much faster the given water depth at which an ignition of the projectile takes place. Geschaf- fen is a solution that is applicable in a simple and cost-effective manner even in bad weather conditions.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus dem folgenden, anhand einer Figur erläuterten Ausführungsbeispiel.Further details and advantages of the invention will become apparent from the following, explained with reference to a figure embodiment.
In der Fig. ist ein Längsschnitt eines mit 1 bezeichneten Geschosses dargestellt. Das Ge- schoss 1 ist erfindungsgemäß als drallstabilisiertes Artilleriegeschoss mit einem Kaliber von z.B. 155 mm ausgebildet und von einem entsprechenden Schiffsgeschütz verschießbar.In the figure, a longitudinal section of a designated 1 projectile is shown. The bullet 1 is inventively used as a spin-stabilized artillery round with a caliber of e.g. 155 mm formed and shootable by a corresponding ship gun.
Das Geschoss 1 weist eine Hülle 2 auf, die einen mit einer Sprengladung 3 (beispielsweise Torpex) gefüllten Hohlraum 4 umschließt. Am vorderen Ende 5 der Stahlhülle 2 ist ein manuell oder elektrisch einstellbarer hydrostatischer Zünder 6 angeordnet, mit dem vor Abschuß des Geschosses 1 die Wassertiefe eingestellt wird, bei welcher der Zünder 6 aktiviert werden soll.The projectile 1 has a shell 2 which encloses a cavity 4 filled with an explosive charge 3 (for example Torpex). At the front end 5 of the steel shell 2, a manually or electrically adjustable hydrostatic igniter 6 is arranged, with the water depth is set before the projectile 1, in which the igniter 6 is to be activated.
Sobald die Position und gegebenenfalls auch der Kurs eines unschädlich zu machenden Unterwasserzieles aufgeklärt wurden, werden die Einstellung des Zünders 6 sowie die Zielkoordinaten berechnet. Nach Einstellung des Zünders 6 auf die berechnete Wassertiefe und nach Richten des Geschützes entsprechend den ermittelten Zielkoordinaten wird das erfindungsgemäße Geschoss 1 in das Zielgebiet verschossen und sinkt dort, bis die an dem Zünder 6 voreingestellte Wassertiefe erreicht ist. Dann initiiert der Zünder 6 über eine Übertragungsladung 7 die Sprengladung 3, um das entsprechende bzw. ausgewählte Ziel unschädlich zu machen, beispielsweise zu zerstören. As soon as the position and possibly also the course of an underwater target which is to be rendered harmless have been clarified, the setting of the igniter 6 and the target coordinates are calculated. After setting the detonator 6 to the calculated water depth and after directing the gun according to the determined target coordinates, the projectile according to the invention 1 is fired into the target area and drops there until the pre-set at the igniter 6 water depth is reached. Then, the igniter 6 initiates the explosive charge 3 via a transfer charge 7 in order to render the corresponding or selected target harmless, for example to destroy it.
