Description

 stabilizing device

description

 The present invention relates to a stabilization device for a vehicle and / or a vehicle payload, wherein the stabilization device a

Detektseinnchtung for detecting an explosion, at least one engine to stabilize the vehicle and / or the vehicle payload, and a

 Control means for activating the at least one engine in the case of an explosion detected by means of the detection device comprises. Furthermore, the invention relates to a method for stabilizing a vehicle and / or a

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 controller.

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 the ground under the effect of explosion. Both in the lift-off phase and in the subsequent Aufsetzphase the crew of the vehicle is high

Accelerations exposed due to the resulting

 Force effects can lead to serious injuries to the crew of the vehicle with u.U. lethal effects.

An apparatus and a method for reducing such vehicle damage to the vehicle crew is known, for example, from the document WO 2010/067093 A1, which discloses a vehicle stabilization system in which the pressure wave of an explosion is detected by means of a pressure sensor. If by means of

Pressure sensor has been detected an explosion. become solid rocket engines ignited to exert a force directed towards the ground on the vehicle and to stabilize the vehicle in this way.

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 level of activation at gsamp l i t building, the delayed start of the solid fuel rocket engines is delayed until the final fuel chamber pressure is established. Furthermore, during the subsequent downward movement towards the ground, the vehicle is additionally accelerated by the thrust generated by the solid-fuel vehicle engines, and the

As a consequence, the impact rate is increased even more.

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.

The object is achieved by a vehicle with the features mentioned in the fact that the engine comprises a propellant and a separate from the propellant discrete ejection mass. the propellant and the discrete

Ejection mass are set up and designed such that upon activation of the engine by the control device, the discrete ejection mass by means of

 Propellant is accelerated under the action of the vehicle and / or the vehicle payload with a stabilizing force. In other words, the discrete ejection mass is due to the pressure effect of the exhaust gases, the blowing agent in the

Activation of the engine developed by the controller, and accelerates 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 immediately with the activation of the engine, the discrete ejection mass is accelerated by means of the propellant and thus substantially immediately a corresponding counterforce is exercised 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 with the time course of the explosion

caused force on the vehicle or on the vehicle payload, so that the stabilizing force compensates for the repulsion-induced force and counteracts a lifting or tipping of the vehicle and / or the vehicle payload. Preferably, the engine is arranged 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 thus the

Vehicle and / or the Fahrz.cugnutzlast is always securely held on the ground.

An expedient embodiment of the invention is characterized in that the engine is a Gehäusecmmcnt having an outlet for the discrete

Ejecting mass includes. 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

Ejecting mass so protected from external influences arranged in the housing element.

A further advantageous embodiment of the invention is characterized in that the discrete ejection mass for a time-delayed disassembly of the discrete

Eject mass arranged disassembly charge with a delay unit. The disassembled charge and the delay unit become the discrete ones

Discharge mass delayed after activation of the engine disassembled. 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 particulates, thereby minimizing potential hazards from the falling discrete ejection mass or portions thereof. According to another preferred embodiment of the invention is between the

Propellant and the discrete ejection mass arranged a movable trained separating element. The separating element is used for the spatial separation of the discrete

Output mass of the propellant. For example, if used as discrete ejection mass a bulk material, the separating element also serves a uniform transmission of the means of propellant when activating the

Engine released forces on the discrete ejection mass.

A further expedient embodiment of the invention is characterized in that the separating element is designed and set up as a receiving element with a receiving space for receiving the discrete ejecting mass. the

Receiving member is disposed in the housing member and movable relative thereto. In other words, the separating element is cup-shaped. On the one hand, this is particularly useful when using a bulk material

Medium as a discrete ejection mass, for example, when using metal granules, saues 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 intake member including the discrete discharge 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 Teilmasscn the discrete ejection mass is ensured and on the other hand, the friction coefficient between the receiving element and the Gchäuseelement only by the materials of the Aufnahmcelemcnts and the inner wall of the housing member is defined. So regardless of the type of material used is the discrete ejection mass.

According to a further preferred Ausluhrungsform the receiving space of the receiving element in the direction of the outlet opening is widening and configured. In other words, the Aumahrneraum is widened to the outlet opening, for example in the form of a truncated cone. This offers the advantage that the ejection mass unhindered and without jamming off or

can be repelled. A further advantageous embodiment of the invention is characterized in that at least one guide element for guiding the Aulhahmeelements is arranged in the housing element on the inside of the housing member and / or on the outside of the receiving element. So the recording element is play and

verklemmungsfrei led and so an otherwise possible tilting of the

Receiving element in the housing element avoided in any case.

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 Aumahmeelement is indeed arranged movable relative to the housing element, but at one

Slipping out of the housing element after activating the engine or the propellant is prevented. In other words, the limiting means is arranged such that the receiving element with its bottom portion under

positive engagement is prevented from loosening from the Gehäuselcrnent. When activating the engine or the propellant so is first the

Recording element, including the discrete ones in the recording frame

Ejecting mass accelerates, but stopped upon reaching an end position by means of the limiting means, while arranged in the receiving element discrete discharge mass veriässt the Aumahmeelement and repelled into the environment.

A / .weckmäßige embodiment of the invention is characterized in that the discrete ejection mass is a bulk solid, a solid body or a fluid. A bulk-like body, such as sand, metal granules or other granular materials or mixtures of high specific weight, decays as well as a fluid 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 scattered over a larger area, so that potential hazards due to the ejection mass in the environment of the vehicle and beyond to a

Minimum be reduced. A preferred embodiment of the invention is characterized by. 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. So the detective is deterring

Detection device only an explosion in the vicinity of the vehicle and / or the vehicle payload 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.

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 several arranged on the vehicle engines, it is on the one hand possible to optimally stabilize the vehicle and / or the vehicle payload and on the other hand, the stabilization forces, for example, the vehicle or

Distribute vehicle utility 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.

A further expedient embodiment of the invention is characterized in that the at least one engine is arranged on the vehicle and / or the Fahrzcugnutzlast such that the discrete ejection mass is accelerated at least substantially in the vertical direction when activating the engine. Advantageously, therefore, the stabilizing force is at least substantially vertical, i. tilted either vertically or at an angle of up to ± 90 ° relative to the vertical. aligned. In other words, the engine is arranged on the vehicle and / or the vehicle payload such that the stabilization force perpendicular to

Substrate on the vehicle or on the vehicle payload acts and this in addition to the weight of the vehicle and / or the vehicle payload on the Untergnmd 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 Fahrzeugnutzlast not only prevented from lifting off the ground, but also tilting of the vehicle or the vehicle payload, for example, in Kiuftemwirkungen by laterally adjacent to the vehicle or the vehicle payload explosions are reliably prevented.

Furthermore, the Autgabe is solved by a corresponding method having the features mentioned in the fact that a discrete ejection mass is accelerated by means of a propellant to pressurize the vehicle and / or the vehicle payload with a stabilizing force. The advantages of the method have already been explained in detail in connection with the stabilizing device according to the invention. To avoid repetition, reference is made to the corresponding text passages.

Further preferred and / or useful features and embodiments of the invention will become apparent from the UnteransprOchen and the description. Particularly preferred embodiments are explained with reference to the accompanying drawings nSher. The drawing shows

Stabilization device 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 the repulsion of the discrete ejection mass 11. The inventive stabilization device is preferably used in armored vehicles and / or vehicle payloads Insert whose structure is protected against external explosive effects. The vehicle and / or the vehicle payload includes or include a

Stabilizer, wherein the stabilizer means for initiating an explosion in the vicinity of the vehicle or the vehicle payload comprises one or more detonator means set up for detection of explosions. The stabilizer means according to the invention is therefore suitable both for the stabilization of vehicles and / or vehicle payloads, i. It can be used to stabilize different vehicle types with and without vehicle payload. However, the present invention is not limited solely to the stabilization of vehicles. Rather, the Stabilisienmgseinrichtung in addition to the stabilization of vehicle payloads, such as trailers, containers, mobile structures and the like, in principle for the stabilization of any non vehicle-bound facilities, for example, to stabilize containers, in principle suitable.

The stabilizer Mgseinrichtung further comprises the at least one engine 10. The engine 10 is designed to stabilize the vehicle and / or the vehicle payload and set Further, the engine 10 is associated with a control device for activating the at least one engine 10 in the case of detected by means of the detection device Explosion is set up and trained. The control device and the detection device are preferably designed as electronic controls. 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 Anzflndmischung. More preferably, the ignition mixture comprises seismic spheres which enable pyrotechnic ignition due to acceleration. The abovementioned priming mixtures are preferably each directly adjacent to the respective igniting mixtures

 Engine 10 arranged so that the ignition mixture is formed in each case with the blowing agent 23 in contact. Alternatively, the detection device is referred to as a shock tube, i. formed as a responsive to pressure surges charge, which is connected by means of the pyrotechnic transmission line designed Steuimgseinrichtung with the respective engine 10 and the propellant 23 So it is

For example, it is possible to arrange the detection device at the bottom of the vehicle and / or the vehicle payload and to activate the engine (s) 10 via the pyrotechnic delay line, if provided by the

A special advantage of the aforementioned pyrotechnic embodiments of the detection and control devices is that they are insensitive to

electromagnetic influences and disturbances are. It is therefore possible to use the stabilizer 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 to be 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. Trabant 23 is particularly preferably a nitrocellulose powder which, in contrast to clock fuels, generates propellant gases with a relatively low combustion temperature in the range up to 1000 ° 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 blowing agent 23 in the combustion chamber 24 comprises further admixtures, for example liquids, in particular water, or liquids in gel form, in order to control the combustion chamber pressure in the combustion chamber 24 or the combustion behavior of the combustion chamber

To influence blowing agent 23. Vort eil Haller way, the combustion chamber 24 is thermally insulated trained and furnished. This has a particularly positive effect when relatively small amounts of propellant 23 are used. since a radiation of heat energy is largely avoided and so a rapid increase in pressure in the combustion chamber 24 is favored.

The engine 10 further comprises a propellant 23 and a separate from the propellant 23 discrete ejection mass 1 1. The propellant 23 and the discrete ejection mass 1 1 are arranged and designed such that in the

Activation of the engine 10 by the controller, the discrete ejection mass 1 1 is accelerated by means of the propellant 23 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.

The propellant 23 serves the purpose of accelerating the discrete

Eject mass 1 1 to generate an inertia of the discrete Ausstoßmassc 1 1 opposite force acting as the stabilizing force on the vehicle and / or the vehicle payload to compensate for the forces acting on the vehicle or the vehicle payload external forces by an explosion and a Prevent lifting or tilting of the vehicle and / or the vehicle payload in any case. For stabilizing the vehicle and / or the vehicle payload during

Acceleration process of the discrete ejection mass caused counterforce arises exclusively by the acceleration process of the discrete ejection mass 1 1. In this case, the propellant 1 1 itself serves only to accelerate and repel the discrete ejection mass 1 1, while the propellant 1 1 itself --- in contrast to a rocket engine - no recoil generated by an output of the propellant 1 1. In other words, the energy carrier, namely the propellant 23 for releasing the acceleration of the discrete ejection mass 11th required amount of energy and the ejected medium, ie the discrete

Ejecting mass 1 1, formed separately.

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 1 1 in the case of activation of the engine 10 through the

Control device. The housing element 12 is formed, 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 mass 11. More preferably, a movably designed separating element 15 is arranged between the propellant 23 and the discrete ejecting mass 1 1. 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 together with the discrete

Molding mass 1 1 accelerated. The separating element 15 is therefore preferably as

Charging mirror formed. 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 partition member 15 is therefore arranged as a sealing member that leakage of combustion gases of the

Propellant 23 prevented. This promotes a rapid pressure increase in the combustion chamber 24 formed by the Gchäuseelement 12 and the Trennelcmcnt 15 so that the conducive to rapid combustion operating pressure of about 300 to 1000 bar can be achieved. Advantageously, the separating element 15 by means of a

 Tear-off, for example, a tear-off, connected to the bottom portion 14. 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 mass 1 1 is clamped or clamped in the housing element 12, so that the ejection mass 1 1 is released only after reaching the predetermined operating pressure. From a dam of the propellant 23 with the vorgenanten Means can be dispensed with, provided that the ejection mass 11 is chosen to be so large that, due to its inertia, it allows the pressure in the combustion chamber 24 to rise to the predetermined operating pressure before the ejection mass 11

Housing element 12 leaves and thus releases the combustion chamber 24 to the atmosphere.

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.

More preferably, 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 in the

Housing element 12 is arranged such that the receiving element 16 is arranged relative to the housing member 12 movable. 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 embodiment of the receiving element 16 is suitable in particular for bulk material discrete output masses 11, such as sand, metal granules or the like, as well as for liquid or gelatinous media.

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

frustoconical formed by the receiving element 16 with his

Side walls 18 and the bottom portion 14 forms the corresponding lateral surfaces of the truncated cone.

Preferably, for the jam-free guidance of the receiving element 16 in the

Housing element 12 on the inside 19 of the housing member 12 or on the

Outside 20 of the receiving element 16 guide elements 21 are arranged. comparisons 5 shows the plan view according to FIG. 5 looking towards the outlet opening 13, including the enlarged detail shown in FIG. The engine 10 comprises at least one of the guide elements 21. Preferably, a plurality of the guide elements 21 are arranged on the inner side 19 of the housing element 12. More preferably, the guide elements 21 are distributed at a uniform distance over the circumference and arranged symmetrically to the longitudinal axis of the Gehäuseclements 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 formed web-shaped. Preferably, the Führungsclement 21 are dimensioned such that they each over

Circle segments with a center angle of at least 30 ° extend. More preferably, the surfaces of the guide elements 21 and the surfaces in contact with these are provided with a sliding coating. The

 Sliding coating is preferably formed as a graphite or Teflon coating.

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 or the separating element 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 Gchäuseelements 12 and so the

 Outlet opening 13 defined. 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, i. chosen smaller than the diameter of the outlet opening 13. Accordingly, the diameter of the bottom portion 14 of the receiving element 16 is greater than that

Set inside diameter of the ring member, so that the bottom portion 14 of the receiving element 16 is secured by positive engagement by means of the ring member against slipping out of the housing member 12. Particularly preferably, the discrete ejecting mass 1 1 is a bulk material-shaped body, for example in the form of sand, granulatformigen substances such as metal granules or the like. Alternatively, the discrete discharge mass 1 1 is a Vollkörpcr. ie formed in one piece. However, the discrete ejection mass 11 is not limited to solids but may alternatively include additional liquid media. Alternatively, the discrete ejection mass 1 1 is formed exclusively as a fluid or gelformigcs medium.

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 1 1 has reached its maximum rise height.

More preferably, the discrete ejection mass 1 1 is formed as a cartridge, for example as a plastic or cardboard cartridge. Preferably, the cartridge is laterally slotted, so that the cartridge when activating the

Disassembling charge can be disassembled into individual parts and the ejection mass 1 1 can disintegrate unhindered into smaller units. Alternatively, it is possible that the ejection mass 1 1 has an enclosure which is designed and arranged so that it dissolves due to the passing ambient air after ejection and the ejection mass 1 1 is released laterally.

For detection of explosions or detonations in the surroundings of the vehicle or the vehicle payload, the detection device comprises at least one arranged on the structure of the vehicle or the vehicle payload

Acceleration sensor. The Beschleunigungsscnsor is designed to detect explosion-induced deformation of the respective structure and

set up. 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 other sensor types for detecting the deformation of the

Vehicle, such as strain gauges.

According to an advantageous embodiment of the invention, a plurality of

Engines 10 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 overlapped by means of the control device activated 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.

Advantageously, the one or the plurality of engines 10 is arranged on the vehicle and / or on the vehicle payload such that the discrete discharge mass 1 1 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 ° and ± 90 ° 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 1 1 is accelerated when activating the engine 10 in the vertical direction, so that the resulting Rückstoßkratt presses as a stabilizing force the vehicle or the vehicle payload in addition to its weight perpendicular to the ground and this prevents it from lifting off the ground.

Alternatively, the plurality of engines 10 are arranged with their longitudinal axis inclined at an angle in the range between 0 ° and ± 90 ° 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 of the vehicle payload located area, effective
