The device has at least one detector (3) and at least one launcher (4) for firing an interception munition, whereby the launcher and the detector are connected to a computer (2). The interception munition has a balloon or parachute structure that is deployed to a functional position to intercept the incoming munition at a distance from the protected object so as to activate its fuse and/or disturb its normal operation.

Description

Panzerabwehrwaffen stellen auch derzeit eine große Bedrohung für Einsatzfahrzeuge von Streitkräften dar. Insbesondere Fahrzeuge mit einem ballistischen Schutz bis 14,5 mm sind gegen Geschosse mit einer Durchschlagleistung bis zu 400 mm RHA ungeschützt. Die Wirkung der panzerbrechenden Waffen beruht auf dem Hohlladungsprinzip, wie auf den Internetseiten http://www.isl.tm.fr/de/scientif/pages/d1/d1 d.html und http://www.panzerlexikon. de/panzeriager2.htm nachlesbar. Der Sprengstoff der Hohlladung wird durch das Auftreffen des Spikes ca. 2 - 5 Cal. vor der Fahrzeugwandung gezündet. Der Druck der Detonationswelle formt die Belegung der Hohlladung zu einem Strahl mit hoher Energiedichte um. Je nach Güte werden Durchschlagsleistungen von bis zu 10 Cal. im optimalen Stand -off erzielt. Der Stand -off bezeichnet den Abstand der Hohlladungsbelegung zur Fahrzeugwandung. Der optimale Stand- off liegt in der Regel im Bereich zwischen 5 - 7 Kaliber. Mit zunehmendem Stand- off nimmt die Durchschlagsleistung fast quadratisch ab. So werden in einem Stand- off von 30 Kalibern nur noch Durchschlagsleistungen von 0,1 Cal. und weniger erreicht.Antitank weapons are also currently a major threat to military emergency vehicles. In particular, vehicles with ballistic protection up to 14.5 mm are unprotected against missiles capable of penetrating up to 400 mm RHA. The effect of the armor-piercing weapons is based on the principle of shaped charge, as on the Internet pages http://www.isl.tm.fr/de/scientif/pages/d1/d1 d.html and http: //www.panzerlexikon. de / panzeriager2.htm readable. The explosive of the shaped charge is approx. 2 - 5 Cal. By the impact of the spike. ignited in front of the vehicle wall. The pressure of the detonation wave transforms the occupation of the shaped charge into a beam with a high energy density. Depending on the quality, breakdown power of up to 10 cal. achieved in optimal state-off. The stand-off designates the distance of the shaped charge assignment to the vehicle wall. The optimal standoff is usually in the range between 5 and 7 calibers. With increasing stand-off, the breakdown power decreases almost quadratically. Thus, in a stand-still of 30 calibers, only breakdown power of 0.1 cal. and less achieved.

Mit der http://www.bwb.org/C1256DF2004FF94C/vwContentByKey/W25Y7HLU375INFODE werden Arten des Panzerschutzes aufgezeigt.With the http://www.bwb.org/C1256DF2004FF94C/vwContentByKey/W25Y7HLU375INFODE types of armor protection are shown.

In der älteren Praxis werden als Schutz vor derartigen Hohlladungsgeschossen Schürzen, Metallgitter oder Sandsäcke verwendet. Neu sind hingegen aktive Schutzsysteme.In the older practice aprons, metal mesh or sandbags are used as protection against such shaped charge projectiles. New, however, are active protection systems.

ARENA ist solch ein in Russland entwickeltes aktives Schutzsystem, bei dem ein entsprechender Radarkontakt gerichtete Ladungssegmente auslöst und so einen Schutzkegel um den Panzer aufbaut. Es wird derzeit von einer deutsch/französischen Firmengruppe weiterentwickelt. (http://www.bmlv.gv.at/facts/geschichte/ruestung 1 4.shtml) Das Ziel dieses aktiven Schutzsystems ist es, den Gefechtskopf etwa 3 - 8 m vor dem Fahrzeug zu treffen und damit den Sprengstoff zur Deflation zu bringen bzw. die Belegung zu treffen.ARENA is such an active protection system developed in Russia, in which a corresponding radar contact triggers directed cargo segments and thus builds a protective cone around the tank.

Die US 4,262,595 A beschreibt eine Antitorpedovorrichtung, die durch eine Rakete gebildet wird, in welcher sich Mittel zum Aufbau einer Schwimmenden Barriere im Wasser befinden. Die Barriere umfasst zudem eine explosive Ladung, die zum Zerstören des durch die Barriere abgefangenen Torpedos gezündet wird.The US 4,262,595 A describes an antitorped device formed by a rocket in which there are means for building a floating barrier in the water. The barrier also includes an explosive charge that is detonated to destroy the torpedo intercepted by the barrier.

Aus der EP 0 687 885 A1 ist ein Fahrzeug mit einem Selbstverteidigungssystem bekannt. Das Wesen hierbei liegt darin, dass eine Anordnung von Startschächten um einen Panzerturm herum aufgebaut ist, die den Rundumschutz innerhalb einer kleinen Wirkungszone des Panzers bilden. Der Startschacht ist jeweils mit einer Munitionseinheit im Kastengehäuse ausgerüstet. Die Munitionseinheit besteht aus einer Treibladung, einer Verbindungsleitung und einem Gegengeschoss. Die Kastenform des Gegengeschosses mit der Sprengladung in der Form einer Platte soll dabei eine wirkungsvolle ebene Detonationswelle in der erforderlichen Richtung bewirken. Das Gegengeschoss ist des Weiteren mit einem Impulskorrekturwerk zum Drehen des Geschosses ausgestattet. Das System selbst besitzt einen Entfernungsmesser innerhalb einer Radarstation sowie eine Signalverarbeitung zur Erzeugung eines Signals zum Ausbringen der Munition. Die Geschossdetonation ist so eingestellt, dass das Geschoss in einem minimalen Sicherheitsabstand vom Panzer ausgelöst wird, wodurch eine schnelle Arbeitswirkung des Systems erreicht werden soll.From the EP 0 687 885 A1 is a vehicle with a self-defense system known. The essence here is that an array of launch shafts is built around a tank turret that provides all-around protection within a small zone of impact of the tank. The launch shaft is equipped with an ammunition unit in the box body. The ammunition unit consists of a propellant, a connecting line and a counter-floor. The box shape of the mating floor with the explosive charge in the form of a plate should cause an effective flat detonation wave in the required direction. The counter floor is also equipped with a pulse correction unit for turning the projectile. The system itself has a rangefinder within a radar station and signal processing to generate a signal to deploy the ammunition. Bullet detonation is set to launch the bullet at a minimum safety distance from the shell, providing a fast work of the system.

Ein Geschoss zum Bekämpfen von freibeweglichen Objekten, welches durch eine Schubkraft in Richtung des zu bekämpfenden Objektes bewegt wird, ist der EP 0 175 914 A entnehmbar. Dabei wird in einem bestimmten Abstand zu dem Objekt aus dem Hülsenkörper des Geschosses ein sich durch den Luftwiderstand großflächig entfaltbares Element so ausgestoßen, dass eine abfangende, richtungsändernde und / oder zerstörende Kollision des entfaltbaren Elementes mit dem Objekt erreicht wird. Vorgesehen ist ein fallschirm-, tennisnetz-, ziehharmonika- oder oktaederartig entfaltbares Element.A projectile for controlling freely movable objects, which is moved by a pushing force in the direction of the object to be controlled, is the EP 0 175 914 A removable. In this case, at a certain distance from the object from the sleeve body of the projectile, a component which can be unfolded extensively by the air resistance is ejected in such a way that an intercepting, direction-changing and / or destructive collision of the deployable element with the object is achieved. A parachute, tennis net, accordion or octahedral deployable element is envisaged.

Weitere Schutzsysteme, wie beispielsweise AWISS der Firma Diehl BGT Defence, sind dem Beitrag http://www.arrows.newmail.ru/defense tank.htm entnehmbar. Ein Aspekt des AWISS ist, dem anfliegenden Hohlladungsgefechtskopf eine Blastladung entgegen zu stellen ( DE 198 47 091 A1 ). Durch die Druckwirkung dieser Blastladung wird der anfliegende Gefechtkopf in einer Entfernung von ca. 10- 30 m vor dem Fahrzeug abgelenkt, deformiert oder zur Deflagration gebracht, mit dem Ziel, die Durchschlagsleistung zu reduzieren.Further protection systems, such as AWISS of Diehl BGT Defense, can be found in the article http://www.arrows.newmail.ru/defense tank.htm . One aspect of AWISS is to provide a blast charge to the approaching shaped charge warhead ( DE 198 47 091 A1 ). Due to the pressure effect of this Blastladung the approaching warhead is deflected at a distance of about 10- 30 m in front of the vehicle, deformed or brought to deflagration, with the aim to reduce the breakdown power.

Nachteilig ist, dass diese Art Schutzsysteme dem anfliegenden Gefechtskopf letal wirkende Ladungen entgegen schießen. Insbesondere im Zuge friedenserhaltender Einsätze sind Kollateralschäden unerwünscht und nicht tolerierbar.The disadvantage is that these types of protection systems shoot against the approaching warhead lethal acting charges. Especially in the course of peacekeeping missions collateral damage is undesirable and intolerable.

Hier greift die Erfindung die Aufgabe auf, eine Schutzvorrichtung bzw. Schutzmaßnahme vorzuschlagen, mit der ein anfliegender Gefechtskopf mittels nicht letaler Mittel gänzlich unschädlich gemacht werden kann.Here, the invention addresses the problem of proposing a protective device or protective measure, with an approaching warhead can be made completely harmless by non-lethal means.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1 sowie 8.The problem is solved by the features of patent claims 1 and 8.

Vorteilhafte Ausführungen sind in den Unteransprüchen aufgeführt.Advantageous embodiments are listed in the subclaims.

Der Erfindung liegt die Idee zugrunde, eine Art Gassack, Airbag oder Stoffsack, d.h., ballonartiges Gebilde mit separaten komprimierten Gasen oder einem beim Verschießen entstehenden Luftpolster etc., mittels einer Abfangmunition dem anfliegenden Gefechtskopf entgegen zu bringen, wobei der Stoffsack sich kurz vor dem Zusammentreffen aufbläst, so dass bei der Kollision ein Zünder des Gefechtskopfes ausgelöst oder gestört wird. Das Gebilde kann sich beispielsweise auch in Form eines Fallschirmes entfalten.The invention is based on the idea to bring a kind of airbag, airbag or cloth bag, ie, balloon-like structure with separate compressed gases or a resulting air bubbles during firing, etc., by means of an intercepting ammunition the approaching warhead, the cloth bag just before the encounter inflates so that an igniter of the warhead is triggered or disturbed in the collision. The structure may, for example, unfold in the form of a parachute.

Sowohl der Abschuss als auch die Initiierung der Abfangmunition sind so ausgelegt, dass der anfliegende Gefechtskopf kurz nach dem Erreichen der vollen Ausdehnung des pyrotechnisch initiierten und ausgeblasenen Stoffsacks auf diesen auftrifft. Durch die hohe kinetische Energie des anfliegenden Geschosses wird der Zünder des Gefechtskopfes unmittelbar beim Auftreffen aktiviert. Die Zündung der Hohlladung erfolgt nun nicht mehr mit einem Abstand von 2 - 3 Kalibern vor der Fahrzeugwandung, sondern in einem bevorzugten Abstand von > 40 Cal. Damit wird die Durchschlagleistung des Gefechtskopfes auf < 0,1 Cal. reduziert und die Fahrzeugwandung nicht penetriert.Both the firing and the initiation of the intercepting ammunition are designed so that the approaching warhead impinges on this shortly after reaching the full extent of the pyrotechnic initiated and blown-out fabric bag. Due to the high kinetic energy of the approaching bullet the detonator of the warhead is activated immediately upon impact. The ignition of the hollow charge is now no longer with a distance of 2 - 3 caliber in front of the vehicle wall, but at a preferred distance of> 40 Cal. Thus, the penetration rate of the warhead is <0.1 Cal. reduced and the vehicle wall is not penetrated.

Möglich sind auch Beschichtungen oder ein härteres Gewebe des Stoffsackes / Fallschirm oder ein Gitter oder Netzstecker, die diesem eine härtere Ausgestaltung geben. Zielsetzung dabei soll nicht nur die Sicherstellung der Zünderauslösung sein, sondern auch die Möglichkeit, Pfeilgeschosse o. dgl. wenigstens minimal zu stören und damit die Durchschlagsleistung zu reduzieren.Also possible are coatings or a harder fabric of the fabric bag / parachute or a grid or power plug, which give it a harder design. objective It should not only be to ensure the detonator, but also the ability to bullet o. The like. At least minimally disturb and thus reduce the breakdown power.

Vorteile dieser Idee sind, dass ein Kollateralschaden durch das Entgegenbringen nicht letal wirkender Mittel ausgeschlossen wird. Die Variante ist gegenüber anderen Schutzsystemen leicht beherrschbar und kostengünstig. Verschossen werden kann die Abfangmunition mit dem Stoffsack mittels herkömmlicher Munitionen und ortsfesten oder richtbaren Werferanlagen. Die Vorrichtung ist leicht adaptierbar und damit nicht nur auf Fahrzeugen nutz- und nachrüstbar. So kann ein Einsatz auch bei Luft- und Seefahrzeugen, Gebäuden etc. erfolgen.Advantages of this idea are that collateral damage is precluded by the provision of non-lethal remedies. The variant is easily manageable and inexpensive compared to other protection systems. The intercepting ammunition can be fired with the cloth bag by means of conventional ammunition and fixed or directional launcher systems. The device is easily adaptable and thus not only usable and retrofitted on vehicles. Thus, a use can also be made in air and sea vehicles, buildings, etc.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden.Reference to an embodiment with drawing, the invention will be explained in more detail.

It shows:

the course of the procedure for intercepting with Fig. 1 detected warhead.

In Fig. 1 ist ein prinzipieller Aufbau einer Detektions- und Abfangvorrichtung 1, bestehend aus wenigstens einem in der Regel Feuerleitrechner 2, zumindest einer Detektionseinrichtung 3 sowie einer, vorzugsweise mehreren, wenigstens vier Abschusseinrichtungen 4. Die Detektionseinrichtung 3 ist in diesem Fall eine Sensoranlage, die Abschusseinrichtung 4 eine herkömmliche Werferanlage, welche beispielsweise richtbar ist (z. B. DE 10 2005 020 177.6 ). Alternativ können auch starre Werfer zum Einsatz kommen, die gefächert am Fahrzeug angebracht sind und eine Hauptbedrohungsrichtung abdecken (z. B. DE 692 03 560 T2 ). Die Werferanlagen 4 sind über eine nicht näher dargestellte Steuerungselektronik mit der Sonaranlage 3 elektrisch verschaltet. Bei der Sensoranlage 3 handelt es sich vorzugsweise um Radarsensoren in Kombination mit IR-Bolometern, wobei für eine Rundumsicht vier Sensoren bevorzugt werden, die miteinander verschaltet diese Rundumsicht gewährleisten. Mit 6 ist eine, einen Gefechtskopf 7 verschießende Person oder dergleichen, d.h., möglicherweise auch ein Fahrzeug bezeichnet, das in einer Entfernung D (Detektionsabstand) zum Fahrzeug 5 beabstandet ist.In Fig. 1 is a basic structure of a detection and interceptor 1, consisting of at least one usually Feuerleitrechner 2, at least one detection device 3 and one, preferably more, at least four Abschusseinrichtungen 4. The detection device 3 is in this case a sensor system, the launching device 4 a conventional launcher, which can be directed, for example (eg. DE 10 2005 020 177.6 ). Alternatively, rigid launchers may be used, which are mounted on the vehicle in a diversified manner and cover a main threat direction (eg. DE 692 03 560 T2 ). The launcher systems 4 are electrically connected via a control electronics, not shown, with the sonar system 3. In the sensor system 3 is preferably radar sensors in combination with IR bolometers, four sensors are preferred for a panoramic view, which interconnect ensure this panoramic view. 6 is a person firing a warhead 7 or the like, ie, possibly also a vehicle, which is at a distance D (detection distance) to the vehicle 5 spaced.

Die Sensoranlage 3 als auch die Werfer 4 können örtlich wahlweise am zu schützenden Objekt, wie einem Fahrzeug 5 angebracht sein bzw. adaptiert werden.The sensor system 3 as well as the launcher 4 can be locally mounted on the object to be protected, such as a vehicle 5 or adapted.

Wird eine Bedrohung durch die Sensoranlage 3 detektiert, so werden über den Feuerleitrechner 3 zunächst die Anflugrichtung sowie Geschwindigkeit des Gefechtkopfes 7 ermittelt. (Fig.2). Die Steuerung aktiviert die Werferanlage 4.3, die entsprechend der ermittelten Anflugdaten den geringsten Richtaufwand erfordert (Fig. 3) und schießt dem Gefechtskopf 7 eine Abfangmunition 8 entgegen (Fig. 4). Kurz vor dem Zusammentreffen von Gefechtskopf 7 und Abfangmunition 8 wird beispielsweise im Abstand von 5 - 8 m zum Fahrzeug 5 über eine fest eingestellte pyrotechnische oder über eine elektronische programmierbare Verzögerung oder über mechanische Auslösung die Abfangmunition 8 initiiert. Durch die Initiierung wird ein Gassatz 9 gezündet, der, ähnlich einem Airbag, einen Stoffsack 10 mit einem Durchmesser von beispielsweise bis zu 1,5 m aufbläst (Fig.5). Sowohl Abschuss als auch zeitliche Initiierung sind so ausgelegt, dass der anfliegende Gefechtskopf 7 kurz vor dem Erreichen der vollen Ausdehnung des Stoffsackes 10 auftrifft. Unmittelbar mit dem Auftreffen wird der Zünder 11 des Gefechtskopfes 7 aktiviert (Fig. 6), so dass sich die Hohlladung 12 ausbildet (Fig.7). Die restliche Durchschlagleistung reicht dann für einen Durchschlag in der Wandung des Fahrzeuges 5 nicht mehr aus.If a threat is detected by the sensor system 3, the approach direction and speed of the battle head 7 are first determined via the fire control computer 3. ( Fig.2 ). The controller activates the launching system 4.3, which requires the least straightening effort according to the determined approach data ( Fig. 3 ) and shoots the warhead 7 an intercepting ammunition 8 ( Fig. 4 ). Shortly before the meeting of warhead 7 and intercepting ammunition 8, the interception ammunition 8 is initiated, for example, at a distance of 5 - 8 m to the vehicle 5 via a fixed pyrotechnic or via an electronic programmable delay or mechanical release. By initiating a gas set 9 is ignited, which inflates, similar to an airbag, a cloth bag 10 with a diameter of, for example, up to 1.5 m ( Figure 5 ). Both firing and time initiation are designed so that the approaching warhead 7 impinges shortly before reaching the full extent of the fabric bag 10. Immediately with the impact of the detonator 11 of the warhead 7 is activated ( Fig. 6 ), so that the shaped charge 12 is formed ( Figure 7 ). The remaining breakdown power is then no longer sufficient for a breakdown in the wall of the vehicle 5.

Durch ein Zeitbudget von
t1= Detektionszeit und Werfereinstellung (beispielsweise 100 ms)
t2= Werfereinrichtung (beispielsweise 120 ms)
t3= Interaktionszeit der Abfangmunition (beispielsweise 80 ms)
ergeben sich Detektionsabstände > 50 m bei Flugkörpern 7 mit v = 150 m/s und > 250 m bei Flugkörpern 7 mit v = 600 m/s.Through a time budget of
t 1 = detection time and throw setting (for example 100 ms)
t 2 = throwing device (for example 120 ms)
t 3 = Interaction time of intercepting ammunition (for example 80 ms)
result detection distances> 50 m for missiles 7 with v = 150 m / s and> 250 m for missiles 7 with v = 600 m / s.
