Description

Des Weiteren betrifft die Erfindung ein Verfahren zur Stabilisierung eines Fahrzeugs und/oder einer Fahrzeugnutzlast beim Einwirken einer Explosion, umfassend die Schritte: Detektieren einer Explosion und Aktivieren mindestens eines Triebwerks im Fall einer detektierten Explosion mittels einer Steuereinrichtung.The present invention relates to a stabilization device for a vehicle and / or a vehicle payload, wherein the stabilization device comprises a detection device for detecting an explosion, at least one engine for stabilizing the vehicle and / or the vehicle payload, and a control device for activating the at least one engine in the case of includes detected by the detection device explosion. The invention further relates to a method for stabilizing a vehicle and / or a vehicle payload upon exposure to an explosion, comprising the steps of: detecting an explosion and activating at least one engine in the event of a detected explosion by means of a control device.

Derartige Fahrzeuge bzw. Verfahren zur Stabilisierung eines Fahrzeugs und/oder einer Fahrzeugnutzlast kommen insbesondere zum Schutz von gepanzerten Fahrzeugen zum Einsatz, die Explosionen bzw. Detonationen, z.B. beim Einsatz in verminten Gebieten, ausgesetzt sind. Eine in der Fahrzeugumgebung ausgelƶste Explosion, beispielsweise beim Ɯberfahren einer Landmine, fĆ¼hrt in der Regel dazu, dass das Fahrzeug unter der Explosionseinwirkung vom Untergrund abhebt. Sowohl in der Abhebephase als auch in der sich anschlieƟenden Aufsetzphase ist die Besatzung des Fahrzeugs hohen Beschleunigungen ausgesetzt, die aufgrund der daraus resultierenden Krafteinwirkungen zu schweren Verletzungen der Besatzung des Fahrzeugs fĆ¼hren kƶnnen mit u.U. letalen Auswirkungen.Such vehicles or methods for stabilizing a vehicle and / or a vehicle payload are used in particular for the protection of armored vehicles, the explosions or detonations, e.g. when used in mined areas. An explosion triggered in the vehicle environment, for example when driving over a landmine, usually leads to the vehicle lifting off from the ground under the effect of an explosion. Both in the lifting phase and in the subsequent Aufsetzphase the crew of the vehicle is exposed to high accelerations, which may lead to serious injury to the crew of the vehicle due to the resulting force effects u.U. lethal effects.

Eine Vorrichtung und ein Verfahren zu Reduktion derartiger Krafteinwirkungen auf die Fahrzeugbesatzung ist beispielsweise aus dem Dokument WO 2010 / 067093 A1 bekannt, das ein Fahrzeugstabilisierungssystem offenbart, bei dem mittels eines Drucksensors die Druckwelle einer Explosion detektiert wird. Sofern mittels des Drucksensors eine Explosion detektiert worden ist, werden Feststoffraketenmotoren gezĆ¼ndet, um eine in Richtung des Untergrunds gerichtete Kraft auf das Fahrzeug auszuĆ¼ben und das Fahrzeug auf diese Weise zu stabilisieren.A device and a method for reducing such forces on the vehicle crew is, for example, from the document WO 2010/067093 A1 discloses a vehicle stabilization system in which by means of a pressure sensor, the pressure wave of an explosion is detected. If an explosion has been detected by means of the pressure sensor, solid-state rocket motors are used ignited to exert a force directed towards the ground on the vehicle and to stabilize the vehicle in this way.

Aufgrund der Schubcharakteristik der Feststoffraktenmotoren kann ein Abheben des Fahrzeugs vom Untergrund jedoch nicht zuverlƤssig verhindert werden. WƤhrend die durch die Explosion hervorgerufene Krafteinwirkung auf das Fahrzeug impulsartig, d.h. innerhalb weniger Millisekunden und mit hoher Anfangsamplitude, einwirkt, setzt die Schubentwicklung der Feststoffraketenmotoren bis zum Aufbau des endgĆ¼ltigen Brennstoffkammerdrucks zeitverzƶgert ein. Des Weiteren wird das Fahrzeug wƤhrend der sich anschlieƟenden AbwƤrtsbewegung in Richtung Untergrund durch den von den Feststoffraktenmotoren erzeugten Schub noch zusƤtzlich beschleunigt und die Aufschlaggeschwindigkeit in der Konsequenz sogar noch mehr erhƶht.However, due to the thrust characteristic of the solid-fuel train engines, lifting of the vehicle from the ground can not be reliably prevented. While the force generated by the explosion on the vehicle impulse-like, i. Within a few milliseconds and with a high initial amplitude, the thrust development of the solid-fuel rocket engines is delayed until the final fuel chamber pressure builds up. Furthermore, during the subsequent downward movement towards the ground, the vehicle is additionally accelerated by the thrust generated by the solid-fuel train engines and, as a consequence, the impact speed is increased even more.

Eine weitere Fahrzeugstabilisierungseinrichtung geht aus dem nicht vorverƶffentlichten Dokument WO 2011 / 148118 hervor. Das dort beschriebene Fahrzeug umfasst Fahrzeugstabilisierungsmittel zum AusstoƟen einer nicht-gasfƶrmigen Masse, um eine Stabilisierungskraft auf das Fahrzeug im Falle einer in der Fahrzeugumgebung detektierten Explosion auszuĆ¼ben. Es ist daher Aufgabe der vorliegenden Erfindung, eine Stabilisierungseinrichtung fĆ¼r ein Fahrzeug und/oder eine Fahrzeugnutzlast vorzuschlagen, das die auf Personen innerhalb des Fahrzeugs bzw. innerhalb der Fahrzeugnutzlast einwirkenden KrƤfte im Falle einer in der Umgebung des Fahrzeugs bzw. der Fahrzeugnutzlast ausgelƶsten Explosion auf ein Minimum reduziert. Des Weiteren besteht die Aufgabe darin, ein entsprechendes Verfahren vorzuschlagen.Another vehicle stabilization device is from the non-prepublished document WO 2011/148118 out. The vehicle described therein includes vehicle stabilization means for discharging a non-gaseous mass to exert a stabilizing force on the vehicle in the event of an explosion detected in the vehicle environment. It is therefore an object of the present invention to propose a stabilization device for a vehicle and / or a vehicle payload which influences the forces acting on persons within the vehicle or within the vehicle payload in the event of an explosion in the vicinity of the vehicle or the vehicle payload Minimum reduced. Furthermore, the object is to propose a corresponding method.

Die Aufgabe wird durch eine Stabilisierungseinrichtung mit den Merkmalen des Anspruchs 1 gelƶst. Mit anderen Worten wird die diskrete AusstoƟmasse durch die Druckwirkung der Abgase, die das Treibmittel bei der Aktivierung des Triebwerks durch die Steuereinrichtung entwickelt, und der daraus resultierenden Kraft beschleunigt. Die dabei entstehende Gegenkraft wirkt auf das Triebwerk und darĆ¼ber auch auf das Fahrzeug und/oder die Fahrzeugnutzlast. Dies bietet den Vorteil, dass unmittelbar mit der Aktivierung des Triebwerks die diskrete AusstoƟmasse mittels des Treibmittels beschleunigt und so im Wesentlichen unverzĆ¼glich eine entsprechende Gegenkraft als Stabilisierungskraft auf das Fahrzeug bzw. auf die Fahrzeugnutzlast ausgeĆ¼bt wird. Der auf diese Weise ausgeĆ¼bte zeitliche Verlauf der Stabilisierungskraft entspricht einem impulsartigen Anstieg quasi zeitgleich mit der Aktivierung des Triebwerks, der wƤhrend des Beschleunigungsvorgangs der diskreten AusstoƟmasse anhƤlt. Der zeitliche Verlauf der Stabilisierungskraft korrespondiert daher mit dem zeitlichen Verlauf der durch die Explosion hervorgerufenen Krafteinwirkung auf das Fahrzeug bzw. auf die Fahrzeugnutzlast, so dass die Stabilisierungskraft die explosionsbedingte Krafteinwirkung kompensiert und einem Abheben bzw. Umkippen des Fahrzeugs und/oder der Fahrzeugnutzlast entgegenwirkt. Vorzugsweise ist das Triebwerk derart eingerichtet und ausgebildet, dass der Betrag der Stabilisierungskraft denjenigen der auf das Fahrzeug bzw. der auf die Fahrzeugnutzlast durch die Explosion einwirkenden Kraft Ć¼bersteigt und so das Fahrzeug und/oder die Fahrzeugnutzlast in jedem Fall sicher auf dem Untergrund gehalten wird.The object is achieved by a stabilization device having the features of claim 1. In other words, the discrete ejection mass is accelerated by the pressure effect of the exhaust gases, which develops the propellant in the activation of the engine by the controller, and the resulting force. The resulting counterforce acts on the engine and also on the vehicle and / or the vehicle payload. This offers the advantage that, directly with the activation of the engine, the discrete ejection mass is accelerated by means of the propellant and thus essentially immediately a corresponding one Counteracting force is exerted as a stabilizing force on the vehicle or on the vehicle payload. The time course of the stabilizing force applied in this way corresponds to a pulse-like increase virtually simultaneously with the activation of the engine which stops during the acceleration process of the discrete discharge mass. The time course of the stabilizing force therefore corresponds to the time profile of the force caused by the explosion force on the vehicle or on the vehicle payload, so that the stabilizing force compensates for the explosion-induced force and counteracts a lifting or tipping of the vehicle and / or the vehicle payload. Preferably, the engine is configured and configured such that the amount of the stabilizing force exceeds that of the force acting on the vehicle or on the vehicle payload by the explosion, and so the vehicle and / or the vehicle payload in each case is securely held on the ground.

ErfindungsgemƤƟ dient das Trennelement der rƤumlichen Trennung der diskreten AusstoƟmasse von dem Treibmittel. Wird beispielsweise als diskrete AusstoƟmasse ein schĆ¼ttgutfƶrmiges Medium verwendet, so dient das Trennelement ferner einer gleichmƤƟigen Ɯbertragung der mittels des Treibmittels beim Aktivieren des Triebwerks freigesetzten KrƤfte auf die diskrete AusstoƟmasse.According to the invention, the separating element serves for the spatial separation of the discrete discharge mass from the propellant. For example, if a bulk material is used as the discrete ejection mass, then the separator also serves to uniformly transfer the forces released by the propellant upon activation of the engine to the discrete ejection mass.

Vorzugsweise ist das Trennelement becherfƶrmig ausgebildet. Dies ist einerseits besonders zweckmƤƟig bei der Verwendung eines schĆ¼ttgutfƶrmigen Mediums als diskrete AusstoƟmasse, beispielsweise beim Einsatz von Metallgranulaten, Sanden oder dergleichen sowie andererseits bei der Verwendung flĆ¼ssiger diskreter AusstoƟmassen, beispielsweise Fluiden, oder Fluiden in Gelform. Beim Aktivieren des Triebwerks bzw. des Treibmittels wird das Aufnahmeelement einschlieƟlich der darin angeordneten diskreten AusstoƟmasse beschleunigt. Das Aufnahmeelement umfasst die diskrete AusstoƟmasse dabei seitlich und zu dem Treibmittel hin, so dass einerseits eine gleichmƤƟige KraftĆ¼bertragung und damit eine in sich homogene Beschleunigung aller Teilmassen der diskreten AusstoƟmasse gewƤhrleistet wird und andererseits der Reibungskoeffizient zwischen dem Aufnahmeelement und dem GehƤuseelement nur durch die Materialien des Aufnahmeelements und der Innenwand des GehƤuseelements definiert ist, also unabhƤngig von der Art des verwendeten Materialtyps der diskreten AusstoƟmasse ist.Preferably, the separating element is cup-shaped. This is on the one hand particularly useful in the use of a bulk material as a discrete ejection mass, for example, when using metal granules, sands or the like, and on the other hand when using liquid discrete ejecting materials, such as fluids, or fluids in gel form. Upon activation of the engine or propellant, the receiving member including the discrete ejection mass disposed therein is accelerated. The receiving element comprises the discrete ejection mass laterally and towards the propellant, so that on the one hand a uniform force transmission and thus homogeneous acceleration of all masses of the discrete ejection mass is ensured and on the other hand, the friction coefficient between the receiving element and the housing element only by the materials of the receiving element and the inner wall of the housing member is defined, that is independent of the type of material used, the discrete ejection mass.

Eine zweckmƤƟige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass das Triebwerk ein GehƤuseelement mit einer Austrittsƶffnung fĆ¼r die diskrete AusstoƟmasse umfasst. Mittels des GehƤuseelements wird die diskrete AusstoƟmasse beim Aktivieren des Triebwerks seitlich gefĆ¼hrt und damit die Bewegungsrichtung der diskreten AusstoƟmasse exakt vorgegeben. Weiterhin sind das Treibmittel und die AusstoƟmasse so geschĆ¼tzt vor ƤuƟeren EinflĆ¼ssen in dem GehƤuseelement angeordnet.An expedient embodiment of the invention is characterized in that the engine comprises a housing element with an outlet opening for the discrete ejection mass. By means of the housing element, the discrete ejection mass is guided laterally when activating the engine and thus exactly predetermined the direction of movement of the discrete ejection mass. Furthermore, the propellant and the ejection mass are so protected from external influences in the housing element.

Eine weitere zweckmƤƟige Ausbildung der Erfindung ist dadurch gekennzeichnet, dass die diskrete AusstoƟmasse eine zum zeitverzƶgerten Zerlegen der diskreten AusstoƟmasse eingerichtete Zerlegungsladung mit einer Verzƶgerungseinheit umfasst. Mittels der Zerlegungsladung und der Verzƶgerungseinheit wird die diskrete AusstoƟmasse zeitverzƶgert nach dem Aktivieren des Triebwerks auseinandergetrieben. So wird sichergestellt, dass die diskrete AusstoƟmasse nicht als kompakte Masse im Anschluss an die Triebswerksaktivierung zu Boden fƤllt, sondern in Form einer Vielzahl kleinerer Partikel, wodurch eine mƶgliche GefƤhrdung durch die herabfallende diskrete AusstoƟmasse bzw. durch Teile davon minimiert wird.A further expedient embodiment of the invention is characterized in that the discrete ejection mass comprises a decomposition charge with a delay unit which is set up for the time-delayed dismantling of the discrete ejection mass. By means of the disassembly charge and the delay unit, the discrete discharge mass is dislocated with a time delay after activation of the engine. This ensures that the discrete ejection mass does not fall to the ground as a compact mass following engine activation, but rather in the form of a multiplicity of smaller particles, thereby minimizing potential hazards from the falling discrete ejection mass or portions thereof.

GemƤƟ einer weiteren bevorzugten AusfĆ¼hrungsform ist der Aufnahmeraum des Aufnahmeelements in Richtung der Austrittsƶffnung sich verbreiternd eingerichtet und ausgebildet. Mit anderen Worten ist der Aufnahmeraum zu der Austrittsƶffnung hin geweitet ausgebildet, beispielsweise in Form eines Kegelstumpfes. Dies bietet den Vorteil, dass die die AusstoƟmasse ungehindert und verklemmungsfrei aus- bzw. abgestoƟen werden kann.According to a further preferred embodiment, the receiving space of the receiving element in the direction of the outlet opening is widening and configured. In other words, the receiving space is formed widened towards the outlet opening, for example in the form of a truncated cone. This offers the advantage that the ejection mass can be unhindered and free from jamming.

Eine weitere zweckmƤƟige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass an der Innenseite des GehƤuseelements und/oder an der AuƟenseite des Aufnahmeelements mindestens ein FĆ¼hrungselement zur FĆ¼hrung des Aufnahmeelements in dem GehƤuseelement angeordnet ist. So wird das Aufnahmeelement spiel- und verklemmungsfrei gefĆ¼hrt und so ein andernfalls mƶgliches Verkanten des Aufnahmeelements in dem GehƤuseelement in jedem Fall vermieden.A further expedient embodiment of the invention is characterized in that at least one guide element for guiding the receiving element is arranged in the housing element on the inside of the housing element and / or on the outside of the receiving element. Thus, the receiving element is guided without play and free from jamming, thus avoiding otherwise possible tilting of the receiving element in the housing element in each case.

GemƤƟ einer weiteren bevorzugten Ausbildung der Erfindung ist im Bereich der Austrittsƶffnung des GehƤuseelements ein Begrenzungsmittel zur Wegbegrenzung des Aufnahmeelements angeordnet. Dies bietet den Vorteil, dass das Aufnahmeelement zwar relativ zu dem GehƤuseelement bewegbar angeordnet ist, jedoch an einem Herausgleiten aus dem GehƤuseelement nach dem Aktivieren des Triebswerks bzw. des Treibmittels gehindert wird. Anders ausgedrĆ¼ckt ist das Begrenzungsmittel derart eingerichtet, dass das Aufnahmeelement mit seinem Bodenbereich unter formschlĆ¼ssigem Eingriff an einem Lƶsen aus dem GehƤuseelement gehindert wird. Beim Aktivieren des Triebwerks bzw. des Treibmittels wird also zunƤchst das Aufnahmeelement einschlieƟlich der im Aufnahmerahm befindlichen diskreten AusstoƟmasse beschleunigt, jedoch beim Erreichen einer Endposition mittels des Begrenzungsmittels angehalten, wƤhrend die in dem Aufnahmeelement angeordnete diskrete AusstoƟmasse das Aufnahmeelement verlƤsst und in die Umgebung abgestoƟen wird.According to a further preferred embodiment of the invention, a limiting means for limiting the travel of the receiving element is arranged in the region of the outlet opening of the housing element. This offers the advantage that the receiving element is indeed arranged to be movable relative to the housing element, but is prevented from sliding out of the housing element after activation of the engine or of the propellant. In other words, the limiting means is arranged such that the receiving element is prevented with its bottom region under positive engagement on a release from the housing element. Thus, upon activation of the engine or propellant, the receiving member including the discrete ejection mass contained in the receptacle is first accelerated but stopped upon reaching an end position by means of the restricting means while the discrete ejection mass disposed in the receptacle exits the receptacle and is repelled into the environment.

Eine zweckmƤƟige Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass die diskrete AusstoƟmasse ein schĆ¼ttgutfƶrmiger Festkƶrper, ein Vollkƶrper oder ein Fluid ist. Ein schĆ¼ttgutfƶrmiger Kƶrper, wie beispielsweise Sand, Metallgranulate oder weitere granulare Stoffe oder Stoffgemische mit hohem spezifischem Eigengewicht, zerfƤllt ebenso wie ein Fluid nach dem Verlassen des Aufnahmeelements bzw. des GehƤuseelements und wƤhrend des Bewegungsvorgangs in der Fahrzeugumgebung aufgrund des entgegenwirkenden Luftwiderstands in eine Vielzahl einzelner Partikel, die Ć¼ber ein grĆ¶ĆŸeres Gebiet verstreut werden, so dass mƶgliche GefƤhrdungen durch die AusstoƟmasse in der Umgebung des Fahrzeugs und darĆ¼ber hinaus auf ein Minimum reduziert werden.An expedient embodiment of the invention is characterized in that the discrete ejection mass is a bulk solid, a solid or a fluid. A bulk-like body, such as sand, metal granules or other granular substances or mixtures of high specific weight, as well as a fluid disintegrates after leaving the receiving element or the housing element and during the movement process in the vehicle environment due to the counteracting air resistance in a plurality of individual particles which are spread over a larger area so as to minimize potential hazards of the ejection mass around the vehicle and beyond.

Eine bevorzugte Weiterbildung der Erfindung zeichnet sich dadurch aus, dass die Detektionseinrichtung mindestens einen Beschleunigungssensor umfasst, der zur Erfassung von explosionsbedingten Verformungen des Fahrzeugs und/oder der Fahrzeugnutzlast ausgebildet und eingerichtet ist. Die Detektionseinrichtung bedingt eine hohe ZuverlƤssigkeit der Explosionserkennung. So detektiert die Detektionseinrichtung nur dann eine Explosion in der Umgebung des Fahrzeugs und/oder der Fahrzeugnutzlast, wenn diese mit einer solch groƟen Kraft auf das Fahrzeug bzw. auf die Fahrzeugnutzlast einwirkt, dass die Struktur re- oder irreversibel verformt wird. Auf diese Weise wird eine Explosionsfehlerkennung zuverlƤssig vermieden.A preferred embodiment of the invention is characterized in that the detection device comprises at least one acceleration sensor which is designed and set up for detecting explosion-induced deformations of the vehicle and / or the vehicle payload. The detection device requires a high reliability of the explosion detection. Thus, the detection device detects an explosion in the vicinity of the vehicle and / or the vehicle payload only when it acts with such a large force on the vehicle or on the vehicle payload that the structure is deformed or irreversibly deformed. In this way, an explosion fault detection is reliably avoided.

GemƤƟ einer weiteren bevorzugten Ausbildung der Erfindung ist eine Mehrzahl der Triebwerke an dem Fahrzeug und/oder der Fahrzeugnutzlast angeordnet, wobei die Steuereinrichtung zum zeitversetzten Aktivieren der Triebwerke ausgebildet und eingerichtet ist. Mittels mehrerer an dem Fahrzeug angeordneter Triebwerke ist es einerseits mƶglich, das Fahrzeug und/oder die Fahrzeugnutzlast optimal zu stabilisieren und andererseits die StabilisierungskrƤfte beispielsweise auf die Fahrzeug- bzw. Fahrzeugnutzlasteckbereiche zu verteilen. Ein weiterer Vorteil besteht darin, dass die Steuereinrichtung zum zeitversetzten Aktivieren der Triebwerke ausgebildet und eingerichtet ist. So kann der Zeitraum der Einwirkung der Stabilisierungskraft auf das Fahrzeug bzw. auf die Fahrzeugnutzlast variiert werden.According to a further preferred embodiment of the invention, a plurality of the engines is arranged on the vehicle and / or the vehicle payload, wherein the control device is designed and set up for the time-delayed activation of the engines. By means of a plurality of engines arranged on the vehicle, it is possible, on the one hand, to optimally stabilize the vehicle and / or the vehicle payload and, on the other hand, to distribute the stabilization forces, for example, to the vehicle or vehicle payload areas. Another advantage is that the control device is designed and set up for time-delayed activation of the engines. Thus, the period of action of the stabilizing force on the vehicle or on the vehicle payload can be varied.

Eine weitere zweckmƤƟige Ausbildung der Erfindung ist dadurch gekennzeichnet, dass das mindestens eine Triebwerk derart an dem Fahrzeug und/oder der Fahrzeugnutzlast angeordnet ist, dass die diskrete AusstoƟmasse zumindest im Wesentlichen in vertikaler Richtung beim Aktivieren des Triebswerks beschleunigt wird. Vorteilhafter Weise ist daher die Stabilisierungskraft zumindest im Wesentlichen vertikal, d.h. entweder vertikal bzw. um einen Winkel von bis zu Ā± 90Ā° gegenĆ¼ber der Vertikalen geneigt, ausgerichtet. Mit anderen Worten ist das Triebwerk derart an dem Fahrzeug und/oder der Fahrzeugnutzlast angeordnet, dass die Stabilisierungskraft senkrecht zum Untergrund auf das Fahrzeug bzw. auf die Fahrzeugnutzlast einwirkt und dieses zusƤtzlich zu der Gewichtskraft des Fahrzeugs und/oder der Fahrzeugnutzlast auf den Untergrund drĆ¼ckt. Das bzw. die Triebwerke kƶnnen jedoch auch geneigt angeordnet sein, so dass die Stabilisierungskraft bzw. mindestens eine der StabilisierungskrƤfte eine Kraftkomponente in horizontaler Richtung umfasst bzw. umfassen. So kann das Fahrzeug und/oder die Fahrzeugnutzlast nicht nur am Abheben vom Untergrund gehindert, sondern zusƤtzlich ein Kippen des Fahrzeugs bzw. der Fahrzeugnutzlast, beispielsweise bei Krafteinwirkungen durch seitlich neben dem Fahrzeug bzw. der Fahrzeugnutzlast erfolgenden Explosionen, zuverlƤssig unterbunden werden.A further expedient embodiment of the invention is characterized in that the at least one engine is arranged on the vehicle and / or the vehicle payload such that the discrete discharge mass is accelerated at least substantially in the vertical direction when activating the engine. Advantageously, therefore, the stabilizing force is at least substantially vertical, that is, either vertically or inclined at an angle of up to Ā± 90 Ā° relative to the vertical, aligned. In other words, the engine is arranged on the vehicle and / or the vehicle payload such that the stabilizing force acts perpendicular to the ground on the vehicle or on the vehicle payload and this in addition to the weight of the vehicle and / or the vehicle payload on the Underground presses. However, the engine or engines may also be arranged inclined so that the stabilizing force or at least one of the stabilizing forces comprises or comprise a force component in the horizontal direction. Thus, the vehicle and / or the vehicle payload not only prevented from lifting off the ground, but also a tilting of the vehicle or the vehicle payload, for example, in force effects by laterally adjacent to the vehicle or the vehicle payload explosions are reliably prevented.

Des Weiteren wird die Aufgabe durch ein entsprechendes Verfahren mit den eingangs genannten Merkmalen dadurch gelƶst, dass eine diskrete AusstoƟmasse mittels eines Treibmittels beschleunigt wird, um das Fahrzeug und/oder die Fahrzeugnutzlast mit einer Stabilisierungskraft zu beaufschlagen. Die Vorteile des Verfahrens sind bereits zuvor im Zusammenhang mit der erfindungsgemƤƟen Stabilisierungseinrichtung detailliert erlƤutert worden. Zur Vermeidung von Wiederholungen wird auf die entsprechenden Textstellen verwiesen.Furthermore, the object is achieved by a corresponding method having the features mentioned in the introduction in that a discrete ejection mass is accelerated by means of a propellant in order to apply a stabilizing force to the vehicle and / or the vehicle payload. The advantages of the method have already been explained in detail previously in connection with the stabilizing device according to the invention. To avoid repetition, reference is made to the corresponding text passages.

Die Figuren 1 bis 4 zeigen jeweils eine Seitenansicht des Triebwerks 10 der Stabilisierungseinrichtung in unterschiedlichen Phasen, nƤmlich im nicht aktivierten Zustand des Triebswerks 10, unmittelbar nach dem Aktivieren, unmittelbar vor dem AbstoƟen einer diskreten AusstoƟmasse 11 bzw. wƤhrend des AbstoƟens der diskreten AusstoƟmasse 11. Die erfindungsgemƤƟe Stabilisierungseinrichtung kommt vorzugsweise bei gepanzerten Fahrzeugen und/oder Fahrzeugnutzlasten zum Einsatz, deren Struktur gegenĆ¼ber Explosionseinwirkungen von auƟen geschĆ¼tzt ist. Das Fahrzeug und/oder die Fahrzeugnutzlast umfasst bzw. umfassen eine Stabilisierungseinrichtung, wobei die Stabilisierungseinrichtung zum Erfassen einer Explosion in der Umgebung des Fahrzeugs bzw. der Fahrzeugnutzlast eine oder mehrere zur Erfassung von Explosionen eingerichtete Detektionseinrichtung(en) umfasst. Die erfindungsgemƤƟe Stabilisierungseinrichtung ist daher sowohl fĆ¼r die Stabilisierung von Fahrzeugen und/oder von Fahrzeugnutzlasten geeignet, d.h. es kƶnnen damit verschiedene Fahrzeugtypen mit und ohne Fahrzeugnutzlast stabilisiert werden. Die vorliegende Erfindung ist jedoch nicht ausschlieƟlich auf die Stabilisierung von Fahrzeugen beschrƤnkt. Vielmehr ist die Stabilisierungseinrichtung neben der Stabilisierung von Fahrzeugnutzlasten, wie FahrzeuganhƤngern, Containern, mobilen Bauwerken und dergleichen, grundsƤtzlich zur Stabilisierung beliebiger nicht Fahrzeug gebundener Einrichtungen, beispielsweise zur Stabilisierung von Containern, grundsƤtzlich geeignet.The FIGS. 1 to 4 each show a side view of the engine 10 of the stabilizer in different phases, namely in the non-activated state of the engine 10, immediately after activation, immediately before the rejection of a discrete ejection mass 11 or during repulsion of the discrete ejection mass 11. The stabilizer according to the invention is preferably used in armored vehicles and / or vehicle payloads whose structure is protected against external explosion effects. The vehicle and / or the vehicle payload comprises a stabilization device, wherein the stabilization device for detecting an explosion in the surroundings of the vehicle or the vehicle payload comprises one or more detection devices configured to detect explosions. The stabilization device according to the invention is therefore suitable both for the stabilization of vehicles and / or vehicle payloads, ie it can be used to stabilize different types of vehicles with and without vehicle payload. However, the present invention is not limited solely to the stabilization of vehicles. Rather, in addition to the stabilization of vehicle payloads, such as vehicle trailers, containers, mobile structures and the like, the stabilization device is fundamentally suitable for stabilizing any non-vehicle-bound devices, for example for stabilizing containers.

Die Stabilisierungseinrichtung umfasst weiter das mindestens eine Triebwerk 10. Das Triebwerk 10 ist zur Stabilisierung des Fahrzeugs und/oder der Fahrzeugnutzlast ausgebildet und eingerichtet. Ferner ist dem Triebwerk 10 eine Steuereinrichtung zugeordnet, die zur Aktivierung des mindestens einen Triebwerks 10 im Fall einer mittels der Detektionseinrichtung erfassten Explosion eingerichtet und ausgebildet ist. Die Steuereinrichtung sowie die Detektionseinrichtung sind vorzugsweise als elektronische Steuerungen ausgebildet.The stabilization device further comprises the at least one engine 10. The engine 10 is designed and set up to stabilize the vehicle and / or the vehicle payload. Furthermore, the engine 10 is assigned a control device which is set up and configured to activate the at least one engine 10 in the event of an explosion detected by the detection device. The control device and the detection device are preferably designed as electronic controls.

GemƤƟ einer bevorzugten alternativen AusfĆ¼hrung der Erfindung sind die Steuereinrichtung und die Detektionseinrichtung als pyrotechnische Einrichtungen ausgebildet und eingerichtet. Die Steuer- und Detektionseinrichtung sind hierbei als stoƟ- und/oder druckempfindliche AnzĆ¼ndmischung ausgebildet. Diese sind derart eingerichtet, dass beim Eintreffen von durch Explosionen bzw. Detonationen ausgelƶsten Druckwellen eine ZĆ¼ndung erfolgt und so das Triebwerk 10 mittels der AnzĆ¼ndmischung aktiviert wird. Weiter bevorzugt umfasst die AnzĆ¼ndmischung seismische KĆ¼gelchen, die ein pyrotechnisches ZĆ¼nden aufgrund von Beschleunigen ermƶglichen. Die vorgenannten AnzĆ¼ndmischungen sind vorzugsweise jeweils unmittelbar an dem jeweiligen Triebwerk 10 angeordnet, so dass die AnzĆ¼ndmischung jeweils mit dem Treibmittel 23 in Kontakt stehend ausgebildet ist. Alternativ ist die Detektionseinrichtung als eine Schocktube, d.h. als eine auf DruckstĆ¶ĆŸe reagierende Ladung ausgebildet, die mittel der als pyrotechnische Ɯbertragungsleitung ausgebildeten Steuerungseinrichtung mit dem jeweiligen Triebwerk 10 bzw. dem Treibmittel 23 verbunden ist. So ist es beispielsweise mƶglich, die Detektionseinrichtung am Boden des Fahrzeugs und/oder der Fahrzeugnutzlast anzuordnen und das bzw. die Triebwerk(e) 10 Ć¼ber die pyrotechnische Verzƶgerungsleitung zu aktivieren, sofern mittels der Detektionseinrichtung eine Explosion oder Detonation detektiert worden ist. Ein besonderer Vorteil der vorgenannten pyrotechnischen Ausbildungen der Detektions-und Steuereinrichtungen besteht darin, dass diese unempfindlich gegenĆ¼ber elektromagnetischen Einwirkungen und Stƶrungen sind. Es ist daher mƶglich, die erfindungsgemƤƟe Stabilisierungseinrichtung beispielsweise in der unmittelbaren Umgebung von Hochleistungsradareinrichtungen einzusetzen, ohne dass die Gefahr einer Fehlaktivierung der Triebwerke 10 durch das Vorhandensein elektromagnetischer Felder hoher FeldstƤrke zu befĆ¼rchten ist. Als Treibmittel 23 finden vorzugsweise Treibladungspulver bzw. SchĆ¼ttpulver Verwendung, beispielsweise aus einbasigem, zweibasigem oder mehrbasigem Material bzw. einem Composite-Material. Besonders bevorzugt ist das Treibmittel 23 ein Nitrocellulose-Pulver, das im Gegensatz zu Raktentreibstoffen Treibgase mit einer relativ niedrigen Verbrennungstemperatur im Bereich bis zu 1000 Ā°K beim ZĆ¼nden erzeugt. Das Treibmittel 23 liegt vorzugsweise in einer Geometrie vor, die eine groƟe AbbrandoberflƤche bereitstellt, beispielsweise als Pulverkƶrner mit einem Durchmesser im Bereich zwischen 2 mm und 6 mm. Optional umfasst das Treibmittel 23 in der Brennkammer 24 weitere Beimengungen, beispielsweise FlĆ¼ssigkeiten, insbesondere Wasser, oder FlĆ¼ssigkeiten in Gelform, um den Brennkammerdruck in der Brennkammer 24 bzw. das Abbrandverhalten des Treibmittels 23 zu beeinflussen.According to a preferred alternative embodiment of the invention, the control device and the detection device are designed and set up as pyrotechnic devices. The control and detection device are in this case designed as a shock and / or pressure-sensitive ignition mixture. These are set up so that upon the arrival of blast caused by explosions or detonation ignition takes place and so the engine 10 is activated by the ignition mixture. More preferably, the igniter mixture comprises seismic beads which allow pyrotechnic ignition due to acceleration. The abovementioned ignition mixtures are preferably each arranged directly on the respective engine 10, so that the igniter mixture is in each case in contact with the propellant 23. Alternatively, the detection device is designed as a shock tube, ie as a charge responsive to pressure surges, which is connected by means of the pyrotechnic transmission line control device to the respective engine 10 or the propellant 23. Thus, it is possible, for example, to arrange the detection device at the floor of the vehicle and / or the vehicle payload and to activate the engine or engines 10 via the pyrotechnic delay line, if an explosion or detonation has been detected by means of the detection device. A particular advantage of the aforementioned pyrotechnic embodiments of the detection and control devices is that they are insensitive to electromagnetic influences and disturbances. It is therefore possible to use the stabilization device according to the invention, for example in the immediate vicinity of high-performance radar devices, without the risk of a malfunction of the engines 10 being feared by the presence of electromagnetic fields of high field strength. As propellant 23 are preferably used propellant powder or bulk powder, for example, einbasigem, dibasic or polybasic material or a composite material. The propellant 23 is particularly preferably a nitrocellulose powder which, unlike clock fuels, generates propellant gases with a relatively low combustion temperature in the range of up to 1000 Ā° K during ignition. The propellant 23 is preferably in a geometry that provides a large burnup surface, for example, as powder grains having a diameter in the range between 2 mm and 6 mm. Optionally, the propellant 23 in the combustion chamber 24 comprises further admixtures, for example liquids, in particular water, or liquids in gel form, in order to influence the combustion chamber pressure in the combustion chamber 24 or the combustion behavior of the propellant 23.

Vorteilhafter Weise ist die Brennkammer 24 thermisch isoliert ausgebildet und eingerichtet. Dies wirkt sich besonders positiv beim Einsatz verhƤltnismƤƟig geringer Mengen des Treibmittels 23 aus, da eine Abstrahlung von WƤrmeenergie weitestgehend vermieden wird und so ein rascher Druckanstieg in der Brennkammer 24 begĆ¼nstigt wird.Advantageously, the combustion chamber 24 is thermally insulated and configured. This has a particularly positive effect on the use of relatively small amounts of propellant 23, since a radiation of heat energy is largely avoided and so a rapid increase in pressure in the combustion chamber 24 is favored.

Das Triebwerk 10 umfasst ferner ein Treibmittel 23 sowie eine von dem Treibmittel 23 getrennt angeordnete diskrete AusstoƟmasse 11. Das Treibmittel 23 sowie die diskrete AusstoƟmasse 11 sind dabei derart eingerichtet und ausgebildet, dass bei der Aktivierung des Triebwerks 10 durch die Steuereinrichtung die diskrete AusstoƟmasse 11 mittels des Treibmittels 23 unter Beaufschlagung des Fahrzeugs und/oder der Fahrzeugnutzlast mit einer Stabilisierungskraft beschleunigt wird. Das Treibmittel 23 ist vorzugsweise als pyrotechnischer Satz, besonders bevorzugt als AusstoƟsatz, ausgebildet, wobei die diskrete AusstoƟmasse aufgrund des Druckanstiegs der beim Abbrennen des pyrotechnischen Satzes entstehenden Verbrennungsgase beschleunigt wird. Alternativ ist das Treibmittel 23 als elektromagnetisches Antriebsmittel, beispielsweise in Form eines elektrischen Linearmotors oder dergleichen, eingerichtet.The engine 10 further comprises a propellant 23 and a separate from the propellant 23 discrete ejection mass 11. The propellant 23 and the discrete ejection mass 11 are arranged and designed such that upon activation of the engine 10 by the control device, the discrete ejection mass 11 means the propellant 23 is accelerated under the action of the vehicle and / or the vehicle payload with a stabilizing force. The propellant 23 is preferably in the form of a pyrotechnic composition, more preferably an expulsion kit, whereby the discrete ejection mass is accelerated due to the pressure increase of the combustion gases produced during the burning of the pyrotechnic composition. Alternatively, the propellant 23 is arranged as an electromagnetic drive means, for example in the form of an electric linear motor or the like.

Das Treibmittel 23 dient dem Zweck, durch das Beschleunigen der diskreten AusstoƟmasse 11 eine der MassentrƤgheit der diskreten AusstoƟmasse 11 entgegen gesetzte Kraft zu erzeugen, die als die Stabilisierungskraft auf das Fahrzeug und/oder die Fahrzeugnutzlast wirkt, um die durch eine Explosion auf das Fahrzeug bzw. die Fahrzeugnutzlast einwirkenden ƤuƟeren KrƤfte zu kompensieren und ein Abheben bzw. Kippen des Fahrzeugs und/oder der Fahrzeugnutzlast in jedem Fall zu verhindern. Die zur Stabilisierung des Fahrzeugs und/oder der Fahrzeugnutzlast beim Beschleunigungsvorgang der diskreten AusstoƟmasse hervorgerufene Gegenkraft entsteht ausschlieƟlich durch den Beschleunigungsvorgang der diskreten AusstoƟmasse 11. Dabei dient das Treibmittel 11 selbst ausschlieƟlich zum Beschleunigung und AbstoƟen der diskreten AusstoƟmasse 11, wƤhrend das Treibmittel 11 selbst - im Gegensatz zu einem Raketentriebwerk - keinen RĆ¼ckstoƟ durch einen AusstoƟ des Treibmittels 11 erzeugt. Anders ausgedrĆ¼ckt sind der EnergietrƤger, nƤmlich das Treibmittel 23, zur Freisetzung der zur Beschleunigung der diskreten AusstoƟmasse 11 erforderlichen Energiemenge und das ausgestoƟene Medium, d.h. die diskrete AusstoƟmasse 11, getrennt ausgebildet.The propellant 23 serves the purpose of generating, by accelerating the discrete ejection mass 11, a force opposing the inertia of the discrete ejection mass 11 acting as the stabilizing force on the vehicle and / or the vehicle payload to cause an explosion on the vehicle or vehicles to compensate for the external forces acting on the vehicle payload and in any event to prevent the vehicle and / or the vehicle payload from being lifted or tilted. The counterforce caused for the stabilization of the vehicle and / or the vehicle payload during the acceleration process of the discrete ejection mass is produced exclusively by the acceleration process of the discrete ejection mass 11. The propellant 11 itself exclusively serves to accelerate and repel the discrete ejection mass 11, while the propellant 11 itself - in the Unlike a rocket engine - no recoil generated by an output of the propellant 11. In other words, the energy carrier, namely the propellant 23, to release the acceleration of the discrete ejection mass 11th required amount of energy and the ejected medium, ie, the discrete ejection mass 11, formed separately.

Vorzugweise umfasst das Triebwerk 10 ein GehƤuseelement 12 mit einer Austrittsƶffnung 13. Die Austrittsƶffnung 13 ermƶglicht den Durchtritt der diskreten AusstoƟmasse 11 im Falle einer Aktivierung des Triebwerks 10 durch die Steuerungseinrichtung. Das GehƤuseelement 12 ist beispielsweise als Rohrelement mit einem geschlossenen Bodenbereich 14 ausgebildet, wobei das Treibmittel 23 zwischen dem Bodenbereich 14 und der diskreten AusstoƟmasse 11 angeordnet ist. ErfindungsgemƤƟ ist zwischen dem Treibmittel 23 und der diskreten AusstoƟmasse 11 ein bewegbar ausgebildetes Trennelement 15 angeordnet. Mit anderen Worten ist das Trennelement 15 relativ zu dem GehƤuseelement 12 bewegbar angeordnet. Beim Aktivieren des Triebwerks 10 wird das Trennelement 15 mittels des Treibmittels 23 in Richtung der Austrittsƶffnung 13 bewegt und zusammen mit der diskreten AusstoƟmasse 11 beschleunigt. Das Trennelement 15 ist daher vorzugsweise als Treibladungsspiegel ausgebildet. Das Trennelement 15 ist vorzugweise selbstlidernd ausgebildet. Dazu ist das Trennelement 15 besonders bevorzugt aus einem duktilen Material gefertigt, so dass sich das Trennelement 15 beim Aktivieren des Triebwerks 10 soweit verformt, dass dieses an die Innenseite des GehƤuseelements 12 gepresst wird und einen dichtende metallische Verbindung bildet. Das Trennelement 15 ist daher als Dichtungselement eingerichtet, dass ein Austreten von Verbrennungsgasen des Treibmittels 23 verhindert. Dies begĆ¼nstigt einen raschen Druckanstieg in der von dem GehƤuseelement 12 und dem Trennelement 15 gebildeten Brennkammer 24, so dass der fĆ¼r eine zĆ¼gige Verbrennung fƶrderliche Betriebsdruck von ca. 300 bis 1000 bar erreicht werden kann. Vorteilhafter Weise ist das Trennelement 15 mittels einer AbreiƟeinrichtung, beispielsweise einer AbreiƟschraube, mit dem Bodenbereich 14 verbunden. Die AbreiƟeinrichtung bewirkt, dass das Trennelement 15 solange fest mit dem Bodenbereich 14 verbunden ist, bis der Druck der von dem Treibmittel 23 freigesetzten Verbrennungsgase einen vorgegebenen Betriebsdruck Ć¼berschreitet. GemƤƟ einer alternativen AusfĆ¼hrung der Erfindung ist anstelle der AbreiƟeinrichtung die AusstoƟmasse 11 in dem GehƤuseelement 12 verspannt oder verklemmt angeordnet, so dass die AusstoƟmasse 11 erst nach Erreichen des vorgegebenen Betriebsdrucks freigegeben wird. Von einer VerdƤmmung des Treibmittels 23 mit den vorgenanten Mitteln kann verzichtet werden, sofern die AusstoƟmasse 11 so groƟ gewƤhlt ist, dass die diese aufgrund ihrer MassentrƤgheit den Anstieg des Drucks in der Brennkammer 24 auf den vorgegebenen Betriebsdruck zulƤsst, bevor die AusstoƟmasse 11 das GehƤuseelement 12 verlƤsst und somit die Brennkammer 24 zur AtmosphƤre hin freigibt.The engine 10 preferably comprises a housing element 12 with an outlet opening 13. The outlet opening 13 allows the passage of the discrete ejection mass 11 in the event of activation of the engine 10 by the control device. The housing element 12 is designed, for example, as a tubular element with a closed bottom region 14, the propellant 23 being arranged between the bottom region 14 and the discrete ejection compound 11. According to the invention, a movable separating element 15 is arranged between the propellant 23 and the discrete ejecting mass 11. In other words, the separating element 15 is arranged to be movable relative to the housing element 12. When activating the engine 10, the separating element 15 is moved by means of the propellant 23 in the direction of the outlet opening 13 and accelerated together with the discrete ejecting mass 11. The separating element 15 is therefore preferably designed as a propellant charge level. The separating element 15 is preferably formed selbstlidernd. For this purpose, the separating element 15 is particularly preferably made of a ductile material, so that the separating element 15 deforms when activating the engine 10 so far that this is pressed against the inside of the housing member 12 and forms a sealing metallic connection. The separating element 15 is therefore designed as a sealing element that prevents the escape of combustion gases of the propellant 23. This promotes a rapid increase in pressure in the combustion chamber 24 formed by the housing element 12 and the separating element 15, so that the operating pressure of approximately 300 to 1000 bar which is conducive to rapid combustion can be achieved. Advantageously, the separating element 15 is connected to the bottom region 14 by means of a tear-off device, for example a tear-off screw. The tear-off device causes the separating element 15 to be firmly connected to the bottom region 14 until the pressure of the combustion gases released by the blowing agent 23 exceeds a predetermined operating pressure. According to an alternative embodiment of the invention, instead of the tear-off device, the ejection compound 11 is clamped or clamped in the housing element 12 so that the ejection compound 11 is released only after reaching the predetermined operating pressure. From a damming of the blowing agent 23 with the vorgenanten Means can be dispensed with, provided that the ejection mass 11 is chosen so large that this allows the increase in pressure in the combustion chamber 24 due to their inertia to the predetermined operating pressure before the ejection mass 11 leaves the housing member 12 and thus the combustion chamber 24 to the atmosphere releases.

Bevorzugt ist das Trennelement 15 im Randbereich, also in dem Bereich, der mit der Innenseite des GehƤuseelements 12 in Kontakt steht, mit einer Gleitbeschichtung versehen, beispielsweise aus Graphit, Teflon oder dergleichen versehen. Auch ist es mƶglich, dass die mit der Innenseite des GehƤuseelements 12 in Kontakt stehenden Bereich der AusstoƟmasse 11 eine Gleitbeschichtung aufweisen.Preferably, the separating element 15 in the edge region, ie in the region which is in contact with the inside of the housing element 12, provided with a sliding coating, for example, made of graphite, Teflon or the like. It is also possible for the region of the ejection compound 11 which is in contact with the inside of the housing element 12 to have a sliding coating.

ErfindungsgemƤƟ ist das Trennelement 15 als ein Aufnahmeelement 16 mit einem Aufnahmeraum 17 ausgebildet und eingerichtet. Der Aufnahmeraum 17 dient der Aufnahme der diskreten AusstoƟmasse 11. Das Aufnahmeelement 16 ist in dem GehƤuseelement 12 derart angeordnet, dass das Aufnahmeelement 16 relativ zu dem GehƤuseelement 12 bewegbar angeordnet ist. Mit anderen Worten entspricht das Aufnahmeelement 17 im Wesentlichen dem Trennelement 15, wobei jedoch das Aufnahmeelement 17 SeitenwƤnde 18 umfasst, die den Aufnahmeraum 17 begrenzen. Die vorgenannte Ausbildung des Aufnahmeelements 16 eignet sich insbesondere fĆ¼r schĆ¼ttgutfƶrmige diskrete AusstoƟmassen n 11, wie Sand, Metallgranulate oder dergleichen sowie fĆ¼r flĆ¼ssige oder gelartige Medien.According to the invention, the separating element 15 is designed and set up as a receiving element 16 with a receiving space 17. The receiving space 17 serves to receive the discrete discharge mass 11. The receiving element 16 is arranged in the housing element 12 such that the receiving element 16 is arranged to be movable relative to the housing element 12. In other words, the receiving element 17 essentially corresponds to the separating element 15, but the receiving element 17 comprises side walls 18, which delimit the receiving space 17. The aforementioned design of the receiving element 16 is particularly suitable for bulk material-shaped discrete ejecting masses 11, such as sand, metal granules or the like, as well as for liquid or gel-like media.

GemƤƟ einer weiteren vorteilhaften Ausbildung der Erfindung ist der Aufnahmeraum 17 des Aufnahmeelements 16 in Richtung der Austrittsƶffnung 13 sich verbreiternd eingerichtet und ausgebildet. Beispielsweise ist der Aufnahmeraum 17 kegelstumpffƶrmig ausgebildet, indem das Aufnahmeelement 16 mit seinen SeitenwƤnden 18 und dem Bodenbereich 14 die entsprechenden MantelflƤchen des Kegelstumpfs bildet.According to a further advantageous embodiment of the invention, the receiving space 17 of the receiving element 16 in the direction of the outlet opening 13 is widening and configured. For example, the receiving space 17 is frusto-conical in that the receiving element 16 forms with its side walls 18 and the bottom area 14 the corresponding lateral surfaces of the truncated cone.

Vorzugsweise sind zur klemmfreien FĆ¼hrung des Aufnahmeelements 16 in dem GehƤuseelement 12 an der Innenseite 19 des GehƤuseelements 12 oder an der AuƟenseite 20 des Aufnahmeelements 16 FĆ¼hrungselemente 21 angeordnet. Vergleiche hierzu die Draufsicht gemƤƟ Figur 5 mit Blickrichtung auf die Austrittsƶffnung 13 einschlieƟlich des in der Figur 5 gezeigten vergrĆ¶ĆŸerten Ausschnitts. Das Triebwerk 10 umfasst mindestens eines der FĆ¼hrungselemente 21, wobei vorzugsweise an der Innenseite 19 des GehƤuseelements 12 mehrere der FĆ¼hrungselemente 21 angeordnet sind. Weiter bevorzugt sind die FĆ¼hrungselemente 21 in gleichmƤƟigem Abstand Ć¼ber den Umfang verteilt und symmetrisch zur LƤngsachse des GehƤuseelements 12 angeordnet. Alternativ kƶnnen das oder die FĆ¼hrungselement(e) 21 an der AuƟenseite 20 des Aufnahmeelements 16 angeordnet sein. Es ist auch mƶglich, dass einige der FĆ¼hrungselemente 21 an der AuƟenseite des Aufnahmeelements 16 und die weitere FĆ¼hrungselemente 21 an der Innenseite 19 des GehƤuseelements 12 angeordnet sind. Die FĆ¼hrungselement 21 sind vorzugsweise stegfƶrmig ausgebildet. Vorzugweise sind die FĆ¼hrungselement 21 derart dimensioniert, dass diese sich jeweils Ć¼ber Kreissegmente mit einem Mittelpunktswinkel von mindestens 30Ā° erstrecken. Weiter bevorzugt sind die OberflƤchen der FĆ¼hrungselemente 21 sowie die mit diesen in Kontakt stehenden FlƤchen mit einer Gleitbeschichtung versehen. Die Gleitbeschichtung ist vorzugsweise als Graphit- oder Teflonbeschichtung ausgebildet.Preferably, guide elements 21 are arranged in the housing element 12 on the inner side 19 of the housing element 12 or on the outer side 20 of the receiving element 16 for the jam-free guidance of the receiving element. comparisons For this purpose, the top view FIG. 5 with a view towards the outlet opening 13 including in the FIG. 5 shown enlarged section. The engine 10 includes at least one of the guide elements 21, wherein preferably on the inside 19 of the housing member 12 more of the guide elements 21 are arranged. More preferably, the guide elements 21 are distributed at a uniform distance over the circumference and arranged symmetrically to the longitudinal axis of the housing member 12. Alternatively, the guide element (s) 21 may be arranged on the outer side 20 of the receiving element 16. It is also possible that some of the guide elements 21 are arranged on the outer side of the receiving element 16 and the further guide elements 21 on the inner side 19 of the housing element 12. The guide element 21 are preferably web-shaped. Preferably, the guide element 21 are dimensioned such that they each extend over circle segments with a center angle of at least 30 Ā°. More preferably, the surfaces of the guide elements 21 and the surfaces in contact with these are provided with a sliding coating. The lubricious coating is preferably formed as a graphite or Teflon coating.

Weiter bevorzugt ist im Bereich der Austrittsƶffnung 13 des GehƤuseelements 12 ein Begrenzungsmittel 22 angeordnet. Die Funktion des Begrenzungsmittels 22 besteht darin, den Weg des Aufnahmeelement 16 bzw. des Trennelements 15 am Ende der Austrittsƶffnung 13 zu begrenzen, so dass dieses zwar innerhalb des GehƤuseelements 12 bewegbar angeordnet ist, jedoch nur insoweit, dass das Aufnahmeelement 16 bzw. das Trennelement 15 das GehƤuseelement beim Aktivieren des Triebwerks 10 nicht vollstƤndig verlassen kann. Vorzugsweise ist das Begrenzungsmittel 22 als Ringelement ausgebildet, dass am Rand des GehƤuseelements 12 angeordnet ist und so die Austrittsƶffnung 13 definiert. Der AuƟendurchmesser des Aufnahmeelements 16 ist im Bereich der SeitenwƤnde 18 kleiner als der Innendurchmesser des Ringelements, d.h. kleiner als der Durchmesser der Austrittsƶffnung 13 gewƤhlt. Entsprechend ist der Durchmesser des Bodenbereichs 14 des Aufnahmeelements 16 grĆ¶ĆŸer als der Innendurchmesser des Ringelements eingerichtet, so dass das der Bodenbereich 14 des Aufnahmeelements 16 unter Formschluss mittels des Ringelements gegen ein Herausgleiten aus dem GehƤuseelement 12 gesichert ist.More preferably, a limiting means 22 is arranged in the region of the outlet opening 13 of the housing member 12. The function of the limiting means 22 is to limit the path of the receiving element 16 and the separating element 15 at the end of the outlet opening 13, so that this is arranged to be movable within the housing member 12, but only to the extent that the receiving element 16 and the separator 15 can not completely leave the housing element when activating the engine 10. Preferably, the limiting means 22 is formed as a ring element, which is arranged on the edge of the housing member 12 and thus defines the outlet opening 13. The outer diameter of the receiving element 16 is smaller in the region of the side walls 18 than the inner diameter of the ring element, that is selected to be smaller than the diameter of the outlet opening 13. Accordingly, the diameter of the bottom portion 14 of the receiving element 16 is set larger than the inner diameter of the ring member, so that the bottom portion 14 of the receiving member 16 is secured by positive engagement by means of the ring member against sliding out of the housing member 12.

Besonders bevorzugt ist die diskrete AusstoƟmasse 11 ein schĆ¼ttgutfƶrmiger Kƶrper, beispielsweise in Form von Sand, granulatfƶrmigen Stoffen, wie Metallgranulaten oder dergleichen. Alternativ ist die diskrete AusstoƟmasse 11 ein Vollkƶrper, d.h. einstĆ¼ckig ausgebildet. Die diskrete AusstoƟmasse 11 ist jedoch nicht nur auf Feststoffe beschrƤnkt sondern kann alternativ zusƤtzlich flĆ¼ssige Medien umfassen. Alternativ ist die diskrete AusstoƟmasse 11 ausschlieƟlich als Fluid oder als gelfƶrmiges Medium ausgebildet.Particularly preferably, the discrete discharge mass 11 is a body in the form of a body, for example in the form of sand, granular substances, such as metal granules or the like. Alternatively, the discrete discharge mass 11 is a solid body, i. integrally formed. However, the discrete ejection mass 11 is not limited to solids but may alternatively include additional liquid media. Alternatively, the discrete ejection mass 11 is formed exclusively as a fluid or as a gel medium.

Weiter bevorzugt umfasst die AusstoƟmasse 11 eine Zerlegungsladung mit einer Verzƶgerungseinheit, die zum zeitverzƶgerten Zerlegen der AusstoƟmasse 11 eingerichtet und ausgebildet ist. Die Verzƶgerungseinheit ist entweder als elektronische Verzƶgerungsschaltung oder als pyrotechnische Verzƶgerungsleitung ausgebildet und eingerichtet. Besonders vorteilhaft wird die Verzƶgerungszeit, die den Zeitraum zwischen dem Aktivieren des Triebwerks 10 und dem Aktivieren der Zerlegungsladung definiert, so gewƤhlt, dass die Zerlegungsladung zu dem Zeitpunkt aktiviert wird, an dem die AusstoƟmasse 11 seine maximale Steighƶhe erreicht hat.More preferably, the ejection mass 11 comprises a decomposition charge with a delay unit, which is set up and designed for the time-delayed dismantling of the ejection mass 11. The delay unit is designed and set up either as an electronic delay circuit or as a pyrotechnic delay line. Particularly advantageously, the delay time, which defines the period between the activation of the engine 10 and the activation of the decomposition charge, is selected such that the decomposition charge is activated at the time at which the discharge mass 11 has reached its maximum rise height.

Weiter bevorzugt ist die diskrete AusstoƟmasse 11 als Kartusche ausgebildet, beispielsweise als Kunststoff- oder Pappkartusche. Vorzugsweise ist die Kartusche seitlich geschlitzt ausgebildet, so dass die Kartusche beim Aktivieren der Zerlegungsladung in Einzelteile zerlegt werden und die AusstoƟmasse 11 ungehindert in kleinere Einheiten zerfallen kann. Alternativ ist es mƶglich, dass die AusstoƟmasse 11 eine UmhĆ¼llung aufweist, die derart ausgebildet und eingerichtet ist, dass diese sich aufgrund der vorbeistrƶmenden Umgebungsluft nach dem AusstoƟen ablƶst und die AusstoƟmasse 11 seitlich freigegeben wird.More preferably, the discrete discharge mass 11 is formed as a cartridge, for example as a plastic or cardboard cartridge. Preferably, the cartridge is laterally slotted, so that the cartridge are disassembled into pieces when activating the decomposition charge and the ejection mass 11 can disintegrate unhindered into smaller units. Alternatively, it is possible for the ejection mass 11 to have an envelope which is designed and arranged in such a way that it dissolves due to the passing ambient air after the ejection and the ejection mass 11 is released laterally.

Zur Erfassung von Explosionen bzw. Detonationen in der Umgebung des Fahrzeugs bzw. der Fahrzeugnutzlast umfasst die Detektionseinrichtung mindestens einen an der an der Struktur des Fahrzeugs oder des Fahrzeugnutzlast angeordneten Beschleunigungssensor. Der Beschleunigungssensor ist dabei zur Erfassung von explosionbedingten Verformungen der jeweiligen Struktur ausgebildet und eingerichtet. Auf diese Weise wird sichergestellt, dass nur im Falle einer tatsƤchlich durch eine Explosion hervorgerufenen beginnenden Verformung des Fahrzeugs mittels der Steuerungseinrichtung als Reaktion auf das vom Beschleunigungssensor abgegebene Signal das Triebwerk 10 aktiviert werden, so dass eine Fehlaktivierung des Triebwerks 10 praktisch ausgeschlossen ist. Alternativ umfasst die Detektionseinrichtung andere Sensortypen zur Erkennung der Verformung des Fahrzeugs, beispielsweise Dehnungsmessstreifen.In order to detect explosions or detonations in the surroundings of the vehicle or the vehicle payload, the detection device comprises at least one acceleration sensor arranged on the structure of the vehicle or the vehicle payload. The acceleration sensor is designed and set up to detect explosion-induced deformations of the respective structure. In this way it is ensured that only in the event of an actual explosion-induced incipient deformation of the vehicle by means of the control device in response to that of the acceleration sensor emitted signal the engine 10 are activated so that a mal-activation of the engine 10 is practically impossible. Alternatively, the detection device comprises other sensor types for detecting the deformation of the vehicle, for example strain gauges.

GemƤƟ einer vorteilhaften Weiterbildung der Erfindung ist eine Mehrzahl der Triebwerke 10 an dem Fahrzeug und/oder der Fahrzeugnutzlast angeordnet. Vorzugsweise ist an Eckbereich mindestens eines der Triebwerke 10 angeordnet, so dass die Anzahl der Triebwerke 10 vorzugsweise mindestens 4 bzw. ein Vielfaches davon betrƤgt. Besonders bevorzugt ist die Steuereinrichtung zum zeitversetzten aktivieren der Triebwerke 10 ausgebildet und eingerichtet. Beispielsweise wird ein Fahrzeug mit einer Masse von ca. 5 t mit vier der Triebwerke 10 ausgestattet, die jeweils einen Triebwerksschub von bis zu 4 x 150 kN erzeugen kƶnnen. Aufgrund der zuvor beschriebenen Ausgestaltung der Triebwerke 10 wird diese SchubgrĆ¶ĆŸe typisch in weniger als 0,5 ms bereitgestellt, so dass der mittels der Triebwerke 10 erzeugte Schub als impulsartige Stabilisierungskraft unmittelbar nach der Detektion der Explosion bzw. eine Detonation auf das Fahrzeug bzw. die Fahrzeugnutzlast ausgeĆ¼bt wird. Mittels der zur zeitversetzten Aktivierung der Triebwerke 10 ausgebildeten Steuerungseinrichtung ist es mƶglich, auch Explosionseinwirkung Ć¼ber einen lƤngeren Zeitraum hinweg entgegen zu wirken. In diesem Fall werden mehrere der Triebwerke 10 sequentiell oder zeitlich Ć¼berlappend mittels der Steuerungseinrichtung aktiviert und so in mehrfacher Folge impulsartige StabilisierungskrƤfte auf das Fahrzeug ausgeĆ¼bt. Die Triebwerke 10 kƶnnen dabei hinsichtlich ihrer Triebwerksleistung abgestuft ausgebildet sein, so dass das der Schub des zuerst zu aktivierenden Triebwerks 10 grĆ¶ĆŸer als derjenige Schub der zeitlich spƤter zu aktivierenden Triebwerke 10 gewƤhlt wird.According to an advantageous development of the invention, a plurality of the engines 10 are arranged on the vehicle and / or the vehicle payload. At least one of the engines 10 is preferably arranged at the corner area, so that the number of engines 10 is preferably at least 4 or a multiple thereof. Particularly preferably, the control device is designed and set up for time-delayed activation of the engines 10. For example, a vehicle with a mass of about 5 tons is equipped with four of the engines 10, each of which can produce an engine thrust of up to 4 x 150 kN. Due to the previously described design of the engines 10, this thrust magnitude is typically provided in less than 0.5 ms so that the thrust generated by the engines 10 acts as a pulse-like stabilizing force immediately after the explosion detection or detonation on the vehicle or vehicle payload is exercised. By means of the time-delayed activation of the engines 10 formed control device, it is possible to counteract even explosion effect over a longer period of time away. In this case, several of the engines 10 are sequentially or temporally overlapping activated by means of the control device and thus applied in multiple series pulse-like stabilization forces on the vehicle. The engines 10 may be designed graduated in terms of their engine performance, so that the thrust of the first to be activated engine 10 is greater than that thrust of the time later to be activated engines 10 is selected.

Vorteilhafterweise ist das eine bzw. die Mehrzahl der Triebwerke 10 derart an dem Fahrzeug und/oder an der Fahrzeugnutzlast angeordnet, dass die diskrete AusstoƟmasse 11 zumindest im Wesentlichen in vertikaler Richtung beim Aktivieren des Triebwerks 10 beschleunigt wird. Beispielsweise ist das Triebwerk 10 mit seiner LƤngsachse parallel oder um einen Winkel im Bereich zwischen 0Ā° und Ā±90Ā° gegenĆ¼ber der Vertikalen angeordnet, so dass die Austrittsƶffnung 13 in eine vom Untergrund abgewandte Richtung zeigt. Ist das Triebwerk 10 bzw. die Mehrzahl der Triebwerke 10 mit der LƤngsachse parallel zur Vertikalen angeordnet, wird die diskrete AusstoƟmasse 11 beim Aktivieren des Triebwerks 10 in vertikaler Richtung beschleunigt, so dass die dabei entstehenden RĆ¼ckstoƟkraft als Stabilisierungskraft das Fahrzeug bzw. die Fahrzeugnutzlast zusƤtzlich zu dessen Gewichtskraft senkrecht auf den Untergrund drĆ¼ckt und diese so am Abheben vom Untergrund hindert.Advantageously, the one or the plurality of engines 10 are arranged on the vehicle and / or on the vehicle payload such that the discrete discharge mass 11 is accelerated at least substantially in the vertical direction when the engine 10 is activated. For example, the engine 10 is arranged with its longitudinal axis parallel or at an angle in the range between 0 Ā° and Ā± 90 Ā° relative to the vertical, so that the outlet opening 13 points in a direction facing away from the ground. Is the engine 10 or the majority of the engines 10th arranged with the longitudinal axis parallel to the vertical, the discrete ejection mass 11 is accelerated when activating the engine 10 in the vertical direction, so that the resulting recoil force as a stabilizing force the vehicle or the vehicle payload in addition to its weight perpendicular to the ground and pushes them so on Lifting off the ground hinders.

Alternativ sind die Mehrzahl der Triebwerke 10 mit ihrer LƤngsachse um einen Winkel im Bereich zwischen 0Ā° und Ā±90Ā° gegenĆ¼ber der Vertikalen geneigt angeordnet. Auf diese Weise kann nicht nur das Abheben des Fahrzeugs bzw. der Fahrzeugnutzlast vom Untergrund sondern zusƤtzlich auch ein Kippen bzw. Rotieren, beispielsweise durch die Einwirkung einer Explosion oder Detonation in einem seitlich vom Fahrzeug bzw. von der Fahrzeugnutzlast gelegenen Bereich, wirksam entgegengewirkt werden.Alternatively, the plurality of engines 10 are arranged with their longitudinal axis inclined at an angle in the range between 0 Ā° and Ā± 90 Ā° relative to the vertical. In this way, not only the lifting of the vehicle or the vehicle payload from the ground but in addition also a tilting or rotating, for example by the action of an explosion or detonation in a side of the vehicle or from the vehicle payload located area, can be effectively counteracted.

Das erfindungsgemƤƟe Verfahren ist im Zusammenhang mit dem erfindungsgemƤƟen Fahrzeug bereits eingehend erlƤutert worden, so dass zur Vermeidung von Wiederholungen auf die entsprechenden Textpassagen verwiesen wird.The method according to the invention has already been explained in detail in connection with the vehicle according to the invention, so that reference is made to the corresponding text passages in order to avoid repetition.
