Abstract

The effect of a detonated warhead on an incoming projectile is countered by a blast from a munition detonated prior to the impact of the warhead. This explosion deflects the explosion of the warhead of the projectile. The optimum time of impact between the incoming projectile and fired munition is calculated on board the object protected by the armor using sensors that extrapolate the time relation between the projectile and munition, so that the latter is detonated at a time when it will affect the rear of the projectile and deflect its path away from the object.

Description

Die Erfindung betrifft ein Verfahren zum Schützen eines Objektes gegen die Einwirkung eines schnellen Projektiles, insbesondere eines gepanzerten Fahrzeuges gegen die Bedrohung durch KE-Pfeilgeschosse.The invention relates to a method for protecting an object against the action a fast projectile, especially an armored vehicle against the threat of KE arrow projectiles.

Als Schutzmaßnahme gegen derartige auch sogen. KE-Penetratoren ist es etwa aus der DE 41 22 622 A1 bekannt, die Hauptpanzerung des zu schützenden Objektes zusätzlich mit einer Reaktivpanzerung aus mit Sprengstoff hinterfütterten Platten zu belegen. Sensorisch wird ermittelt, welcher Bereich des zu schützenden Objektes vom anfliegenden Projektil bedroht wird, um aus diesem Bereich dem Projektil eine Platte entgegenzuschleudern und dadurch wenigstens die Kinematik, im allgemeinen aber auch die Kinetik des Angreifers so zu stören, daß er selbst im Falle eines Treffers nur noch unschädliche Restwirkung ausübt, weil z. B. das Pfeilgeschoß nicht mehr in Längsrichtung sondern dagegen angestellt und deshalb ohne große Durchschlagskraft seitlich auf das zu schützende Objekt trifftAs a protective measure against such. KE penetrators it is about DE 41 22 622 A1, the main armor of the object to be protected additionally with reactive armor made of explosives-backed plates to prove. The sensor determines which area of the object to be protected is threatened by the approaching projectile, from this area the projectile throwing a plate at it and thereby at least the kinematics, in general but also to disrupt the attacker's kinetics so that he himself in the event of a hit only has a harmless residual effect, because e.g. B. the arrow projectile no longer in the longitudinal direction but against it and therefore without high penetration force hits the object to be protected from the side

Bei der aus der DT 977 984 bekannten Reaktivpanzerung wird die sprengstoffbeschleunigte Platte nicht dem anfliegenden Projektil entgegengeschleudert sondern bei dessen Aufschlag quer zur Aufschlagrichtung verschoben, um die Einwirkungsrichtung auszulenken. In the reactive armor known from DT 977 984, the explosive accelerated Plate not thrown at the approaching projectile but instead at its impact shifted transversely to the direction of impact to the direction of action deflect.

Nachteilig an der an sich funktionstüchtigen Reaktivpanzerung ist die große zusätzliche Belastung des zu schützenden Objektes, nämlich stationär durch die Masse der Reaktionsplatten und dynamisch durch die Reaktionswirkung beim sprengstoffbeschleunigten Bewegen einer Platte. Darüber hinaus ist es bei Fahrzeugen als den zu schützenden Objekten nachteilig, daß aus konstruktiven Gründen der Vortriebsbereich (Ketten oder Räder von vorne) weitgehend ungeschützt bleibt Das stellt eine besondere Gefährdung gerade in der Hauptbedrohungsrichtung eines Kampffahrzeuges dar. Nachteilig ist femer, daß eine einmal ausgelöste Reaktionsplatte einen ungeschützten Bereich hinterläßt, weil eine solche Lücke erst im Etappenmagazin nach Wiederherrichten der Plattenhalterungen durch Einbau einer neuen sprengstoffhinterfütterten Reaktionsplatte wieder geschlossen werden kann.A disadvantage of the reactive armor, which is functional per se, is the large additional armor Load on the object to be protected, namely stationary by the mass of the reaction plates and dynamic due to the reaction effect when accelerating explosives Moving a plate. In addition, it is considered in vehicles the objects to be protected disadvantageous that the tunneling area for design reasons (Chains or wheels from the front) That remains largely unprotected poses a particular threat especially in the main threat direction Combat vehicle. Another disadvantage is that a reaction plate once triggered leaves an unprotected area because such a gap only appears in the stage magazine after restoring the plate brackets by installing a new one explosive-backed reaction plate can be closed again.

Aus der DE 35 36 328 A1 ist es bekannt, ein Minenfeld aus kardanisch aufgehängten Minen als Hubschraubersperre einzusetzen. Durch Extrapolation mittels eines Erfassungsgerätes soll über einen bestimmten Zeitbereich eine Voraussage über die Flugbahn des Hubschraubers möglich sein, was aber wegen der Hoover-Fähigkeit eines Hubschraubers fraglich ist. Die auf einen Vorhaltepunkt ausgerichteten Minen werden zeitgleich abgeschossen. Aufgrund deren Streuwirkung soll der Hubschrauber kampfunfähig gemacht werden. Zum Schutz eines in der Ebene des Minenfeldes aber abseits dessen sich bewegenden gepanzerten Fahrzeugs gegen KE-Penetratoren kommt diese stationäre Sperre jedoch nicht in Betracht.From DE 35 36 328 A1 it is known to mount a mine field from gimbal Use mines as a helicopter lock. By extrapolation using a Acquisition device should predict over a certain time range the helicopter's trajectory may be possible, but because of the Hoover's ability a helicopter is questionable. The targeting point Mines are shot down at the same time. Because of their scattering effect the helicopter should be incapacitated. To protect one in the Level of the minefield but away from the moving armored vehicle this stationary lock cannot be used against KE penetrators.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Schutz gegen schnelle Projektile wie insbesondere KE-Penetratoren zu schaffen, der das zu schützende Objekt weniger beansprucht und nach seiner Auslösung leichter wieder reaktivierbar ist und der insbesondere eine optimale Störwirkung auf das angreifende Geschoß ausübt.The invention is therefore based on the object of protecting against rapid To create projectiles such as KE penetrators in particular, which is to be protected Object less stressed and easier to reactivate after it has been released is and in particular an optimal disruptive effect on the attacking projectile exercises.

Diese Aufgabe ist erfindungsgemäß nach dem Patentanspruch 1 dadurch gelöst, daß das schnell anfliegende Projektil, insbesondere ein mittels Heckflügeln stabilisierte Pfeil-Wuchtgeschoß, infolge Querkrafteinwirkung hinter seinem Schwerpunkt aus der Angriffsbahn abgelenkt oder wenigstens aus der Angriffsrichtung verschwenkt wird; nämlich indem dem angreifenden Projektil aus einem problemlos nachladbaren Startrohr an Bord des zu schützenden Objektes eine Blast-Granate entgegengeschickt wird, deren ungerichtet wirkender und deshalb sehr preiswerter Gefechtskopf zum optimalen Annäherungszeitpunkt an das angreifende Projektil gezündet wird, um eine Gasschwaden- und Reaktionsdruckwelle gegen das abzuwehrende Projektil freizusetzen. Optimal ist dieser Einwirkungs-Zeitpunkt, wenn die Blastwirkung sich nicht vornehmlich und insbesondere nicht zuerst auf den Frontbereich, sondern auf den Heckbereich des angreifenden Geschosses mit seinem infolge der Stabilisierungsflossen vergrößerten Heckquerschnitt auswirkt. Denn andernfalls könnte eine im Frontbereich schon bewirkte Auslenkung durch daraufhin noch erfolgende Querbeanspruchung des Heckbereiches wieder rückgängig gemacht werden. According to the invention, this object is achieved according to claim 1 in that that the quickly approaching projectile, especially one stabilized by means of rear wings Arrow balancing projectile, due to the action of transverse forces behind its center of gravity distracted from the attack path or at least from the direction of attack is pivoted; namely by hitting the attacking projectile from a problem a blast grenade on the object to be protected is sent, whose omnidirectional and therefore very inexpensive Warhead at the optimal time to approach the attacking projectile is ignited to a gas vapor and reaction pressure wave against the one to be warded off Release projectile. This time of exposure is optimal if the blast effect does not primarily affect the blast in particular Front area, but to the rear area of the attacking projectile with its due to the stabilizing fins enlarged rear cross-section affects. Otherwise, a deflection already caused in the front area could result from the transverse stress on the rear area that subsequently occurs can be reversed again be made.

Aufgrund der hohen Relativgeschwindigkeit zwischen dem schnellen angreifenden Projektil und der ihm entgegengeschossenen Abwehr-Blastgranate ist der optimale Einwirkungs-Zeitpunkt erfindungsgemäß relativ eng einzugrenzen, nämlich auf einen Zeitbereich in der Größenordnung einer halben Millisekunde im Zuge des möglichst dichten Vorbeiflugs der Abwehrgranate am angreifenden Projektil. Um diese kritische Wirkzeitspanne einzuhalten, wird aus der Kinematik des angreifenden Projektils und aus der Kinematik der Abwehrgranate unter Berücksichtigung von systembedingten Verzögerungszeiten der optimale Zündkommandozeitpunkt für den Blast-Gefechtskopf bestimmt.Because of the high relative speed between the fast attacking The projectile and the defensive blast grenade shot against it is the optimal one To narrow the point of action according to the invention relatively narrowly, namely to a time range on the order of half a millisecond in the course of the The defense grenade flies as close as possible to the attacking projectile. Around Adhering to this critical period of action will result from the kinematics of the attacker Projectile and from the kinematics of the defense grenade under consideration the optimal ignition command time of system-related delay times destined for the blast warhead.

Die Annäherungskinematik des abzuwehrenden Projektils wird nach Richtung und Geschwindigkeit mittels eines Sensors an Bord des zu schützenden Objektes ausgemessen, wie er etwa in der DE 40 08 395 A1 zur Bestimmung einer zu aktivierenden Reaktionsplatte beschrieben ist. Dieser Sensor kann auch die Bewegung der vom Objekt dem Projektil entgegengeschossenen Blastgranate erfassen, um dann im Steuerrechner an Bord des zu schützenden Objektes aus den beiden Geschwindigkeitsvektoren den vorausliegenden Rendezvouszeitpunkt zu extrapolieren, also im Zuge des Vorbeiflugs den Zeitpunkt der dichtesten hinter dem Mittenbereich des Projektils gelegenen Annäherung der Blastgranate an das angreifende Projektil.The approach kinematics of the projectile to be warded off are in the direction and Speed measured by means of a sensor on board the object to be protected, as it is about in DE 40 08 395 A1 for determining one to be activated Reaction plate is described. This sensor can also detect the movement of the Detect the blast grenade shot from the object at the projectile and then in the control computer on board the object to be protected from the two speed vectors to extrapolate the date of the rendezvous ahead in the course of the flyby the time of the densest behind the middle area the blast grenade to the attacking projectile.

Für die Vorausbestimmung des Rendezvouszeitpunktes kann aber die Blastgranate auch selbst mit einem (Annäherungs-) Sensor zum Messen der zeitlichen Änderung des Restabstandes zum anfliegenden Projektil ausgestattet sein. Dieser mitfliegende Sensor ist dann zweckmäßigerweise über eine Kommandoverbindung zur Blastgranate auf den Steuerrechner an Bord des zu schützenden Objektes geschaltet. Bei solcher bidirektionalen Datenverbindung kann es sich um eine Leitstrahlstrecke mit gesteuertem Reflektor an Bord der Blastgranate handeln, bevorzugt aber um einen Steuerdraht oder dergleichen elektrischen Leiter zur Zweirichtungs-Informationsübermittlung, über welchen ohnehin die Zündeinrichtung der Blastgranate mit dem Steuerrechner an Bord des zu schützenden Objektes bis zum Ausführen des Zündkommandos verbunden bleibt.The blast grenade can be used to predict the date of the rendezvous even with a (proximity) sensor to measure the change over time the remaining distance to the approaching projectile. This one flying along The sensor is then expediently via a command connection Blast grenade switched to the control computer on board the object to be protected. Such a bidirectional data connection can be a Acting a beamline with a controlled reflector on board the blast grenade, preferred but around a control wire or the like electrical conductor for bidirectional information transmission, through which the ignition device of the Blast grenade with the control computer on board the object to be protected up to Execution of the firing command remains connected.

Mit dem Zünden des Blast-Gefechtskopfes wird aber nicht bis zum Rendezvouszeitpunkt zugewartet. Vielmehr erfolgt, wenn aus den sensorisch ermittelten Bewegungsgleichungen der Rendezvouszeitpunkt bestimmt ist, eine Vorverlegung des Zündkomandozeitpunktes vor jenen extrapolierten Rendezvouszeitpunkt. Der Betrag dieser Vorverlegung bestimmt sich aus verschiedenen Verzögerungsanteilen, die insbesondere die Laufzeit der Blastwelle über den aktuell gegebenen Rendezvousabstand zum Heckbereich des abzuwehrenden Projektiles zum Inhalt hat, zuzüglich der Zündverzugszeit (also der Reaktionszeit zwischen Ankunft des Zündkommandos in der Granate und Detonation des Blastgefechtskopfes) und zuzüglich der Übertragungs- und Verarbeitungszeiten für die Erfassung von Sensordaten, deren Übermittlung an den Steuerrechner sowie deren Verarbeitung und Übermittlung als das Zündkomando an die Blastgranate.The blast warhead is not fired until the rendezvous waited. Rather, it takes place from the sensed equations of motion the date of the rendezvous is determined, an advance the ignition command time before that extrapolated rendezvous time. The The amount of this advance is determined from various delay components, which in particular the duration of the blast wave over the currently given rendezvous distance to the rear of the projectile to be defended, plus the ignition delay (i.e. the reaction time between arrival of the Firing commands in the grenade and detonation of the blast warhead) and plus the transmission and processing times for the acquisition of sensor data, their transmission to the control computer and their processing and Transmission as the firing command to the blast grenade.

So wird also erfindungsgemäß aus den sensorisch erfaßten Bahn- bzw. Annäherungsdaten der zu erwartende Rendezvouszeitpunkt extrapoliert, aber das Zündkomando für den Blastgefechtskopf um die Summe systembedingter Verzugszeiten vor jenen Rendezvouszeitpunkt vorgezogen, damit die Blastwirkung gerade innerhalb des aus der hohen Passagegeschwindigkeit resultierenden nur sehr kurzen Wirkzeitfensters auf den Heckbereich des abzuwehrenden Projektiles trifft und dieses trotz nur geringen Einsatzes an Sprengstoffmenge merklich aus seiner momentanen Anflugrichtung auslenkt. Dadurch verfehlt das Projektil sein Ziel, jedenfalls trifft es nicht in Längsrichtung sondern allenfalls in Querrichtung und somit ohne große Durchschlagswirkung auf das gefährdete Objekt.Thus, according to the invention, the sensor-acquired path or approach data becomes the expected date of the rendezvous extrapolates, but the firing command for the blast warhead by the sum of system-related delay times before that date, so that the blast effect just inside the very short one resulting from the high passenger speed The effective time window hits the rear area of the projectile to be blocked and this, despite only a small amount of explosives, is noticeable from its current level Deflected approach direction. As a result, the projectile misses its target, at least it does not hit in the longitudinal direction but at best in the transverse direction and thus without any major impact on the endangered object.

Zusammenfassend kann deshalb festgestellt werden, daß nach vorliegender Erfindung zur Abwehr eines angreifenden heckflügel-stabilisierten Projektiles wie insbesondere eines KE-Penetrators diesem vom zu schützenden Objekt her eine Blastgranate entgegengeschossen wird, deren Gasschwaden- und Reaktionsdruck-Blastwelle des gezündeten Blastgefechtskopfes vorwiegend auf den Heckbereich des angreifenden Projektiles einwirkt und dieses dadurch aus der Angriffsrichtung heraus verschwenkt, damit das angegriffene Objekt verfehlt oder wenigstens nicht in Längsrichtung getroffen wird. Weil wegen der hohen Passagegeschwindigkeit nur ein sehr kleines nutzbares Einwirkungs-Zeitfenster besteht, wird für optimale Blastwirkung aus der sensorisch erfaßten Annäherungskinematik der Rendezvouszeitpunkt der dichtesten Annäherung der Blastgranate an das Heck des abzuwehrenden Projektiles extrapoliert aber der Blastgefechtskopf um systembedingte Verzugszeiten gegenüber jenem Rendezvouszeitpunkt vorverlegt zur Zündung angesteuert. Bei den für die zeitliche Vorverlegung zu berücksichtigenden systembedingten Verzugszeiten handelt es insbesondere um die Signalübertragungs- und Verarbeitungszeiten zwischen Sensoren und Steuerrechner sowie Steuerrechner und Zündeinrichtung, um die Zündverzugszeit zwischen Ankunft des Zündkommandos und Zünden des Blastgefechtskopfes sowie um die Laufzeit der Blastwelle über die dann gegebene Distanz von der Blastgranate zum Heckbereich des abzuwehrenden Projektiles.In summary, it can therefore be stated that according to the present invention to ward off an attacking rear wing-stabilized projectile such as in particular of a KE penetrator this one from the object to be protected Blast grenade is shot, its gas vapor and reaction pressure blast wave of the fired blast warhead mainly on the rear area of the attacking projectile, and this from the direction of attack swung out so that the attacked object misses or at least is not hit lengthways. Because of the high passenger speed there is only a very small usable exposure time window for optimal blast effect from the sensed proximity kinematics of the Rendezvous time of the closest approach of the blast grenade to the rear of the The blast warhead extrapolates projectiles to be warded off by system-related ones Delay times compared to that rendezvous time brought forward to the ignition driven. For those to be considered for the advance system-related delay times are particularly the signal transmission and processing times between sensors and control computers as well as control computers and ignition device to adjust the ignition delay time between arrival of the Firing commands and firing of the blast warhead as well as the duration of the Blast wave over the then given distance from the blast grenade to the rear area the projectile to be warded off.
