Description

Die Erfindung bezieht sich auf ein Gerät und ein Verfahren zum Testen des dynamischen Verhaltens, insbesondere der Richtgenauigkeit, von Rohrwaffen.The invention relates to an apparatus and a method for testing the dynamic behavior, especially the accuracy of direction, of barrel weapons.

Es ist bereits eine stationäre Einrichtung bekannt, mit der das statische Verhalten von Geschützen oder Startbehältern für Flugkörper, insbesondere Rohrwaffen, getestet werden kann. Darunter ist insbesondere der Test der Stabilisierungseinrichtung und der Einrichtungen zur Waffensteuerung zu verstehen. Die bekannte stationäre Einrichtung wird insbesondere auch für den Abgleich der genannten Stabilisierungs- und Steuerungseinrichtungen des Geschützes mit der Radar- und Feuerleiteinrichtung des Waffensystems eingesetzt.A stationary facility is already known with the static behavior of guns or launch tanks tested for missiles, especially barrel weapons can be. This includes in particular the test of the stabilization device and weapons control facilities to understand. The well-known stationary facility is used in particular for the comparison of the above Stabilization and control devices of the gun with the radar and fire control system of the weapon system used.

Ein derartiger Abgleich ist insbesondere nach der Installation oder Reparatur eines Geschützes notwendig.Such a comparison is particularly important after installation or repair of a gun necessary.

Mit der bekannten stationären Einrichtung ist es jedoch nicht möglich, ein auf einem Waffensystem, wie beispielsweise einem Schiff oder Panzer, installiertes Geschütz unter Einsatzbedingungen insbesondere hinsichtlich seiner Richtgenauigkeit zu testen.With the known stationary device, however, it is not possible one on a weapon system, such as a ship or tank, installed gun under operating conditions especially with regard to its Test accuracy.

Aus der US-A-4936190 ist ein elektrooptisches Visiersystem bekannt, das eine Video-Kamera an dem Rohr eines Geschützes als Visiereinrichtung nutzt. Die Video-Kamera wird dazu auf der Außenwand des Geschützrohres befestigt. Damit gehen Winkelfehler zwischen der Außenwand des Geschützrohres und der Seelenachse in die Visiergenauigkeit ein. Außerdem ist die von der Kamera bestimmte Visierachse naturgemäß gegen die Schußrichtung versetzt. Dieses Dokument ist als der nächtsliegenden Stand der Technik anzusehen.From US-A-4936190 is an electro-optical sighting system known that a video camera on the barrel of a gun used as a sighting device. The video camera will attached to the outer wall of the gun barrel. In order to there are angular errors between the outer wall of the gun barrel and the soul axis in the sighting accuracy. In addition, the sight axis determined by the camera naturally offset against the direction of fire. This document is considered to be the state of the art at night.

Aus der DE-A-2951108 ist eine Bildwiedergabeeinrichtung bekannt, bei der ein von einer Video-Kamera geliefertes Bild zusammen mit einem eingeblendeten Fadenkreuz wiedergegeben wird.DE-A-2951108 is an image display device known in which a supplied by a video camera Image displayed together with a displayed crosshair becomes.

Aus der nachveröffentlichten EP-B-0314721 ist ein Kalibrierungsverfahren für eine Feuerleiteinrichtung bekannt, das dazu dient, die Ausrichtung von Geschützen zu verbessern. Die entsprechende Einrichtung enthält ein oder mehrere Geschütze, die mit Geschützsensoren ausgestattet sind. Die Geschützsensoren sind an dem Rohr, d.h. gegen dessen Seelenachse versetzt angeordnet. Zusätzlich sind Richtgeräte mit Radar (Zielverfolgungsradar) sowie ein Rundsuchradar vorgesehen. Zum rechnerischen Abgleich des Zielverfolgungsradars auf die Schußlinien der Geschütze, werden in einer Testmessung mit einem im Raum bewegten Zielkörper, auf den sowohl der Zielverfolgungsradar als auch die Geschützsensoren ansprechen, die Daten des Zielverfolgungsradars und der Geschützsenoren in ausgewählten Raumpunkten miteinander abgeglichen. Dies erfolgt durch Bestimmung der Fehlausrichtung der Geschütze mittels eines Sichtgeräts, das an die Geschützsensoren angeschlossen ist. Die Fehlausrichtung tritt als Ablage des Zielkörpers von der Mitte eines Fadenkreuzes in Erscheinung. Mittels eines geeigneten Eingabegeräts, wie eines Trackballs, Joysticks oder dgl., wird das Fadenkreuz auf die Mitte des Ziels eingestellt und aus der erfolgten Einstellung ein Korrekturwert ermittelt und abgespeichert. Die Korrekturwerte ergeben Korrekurvektoren die dann beim praktischen Schießbetrieb berücksichtigt werden.From the subsequently published EP-B-0314721 is a calibration method for a fire control device is known, which serves the Improve gun alignment. The corresponding Facility contains one or more guns that are designed with Gun sensors are equipped. The gun sensors are on the pipe, i.e. offset against its soul axis arranged. In addition, aiming devices with radar (tracking radar) as well as a search radar. To the mathematical comparison of the target radar to the Firing lines of the guns are included in a test measurement a target body moved in space, on which both the Targeting radar as well as targeting the gun sensors, the data of the tracking radar and the Gun sensors in selected spatial points with each other adjusted. This is done by determining the misalignment the guns by means of a sighting device the gun sensors is connected. The misalignment occurs as a deposit of the target body from the middle of one Crosshair in appearance. By means of a suitable Input devices, such as a trackball, joystick or the like, the crosshair is set to the center of the target and a correction value is determined from the setting made and saved. The correction values result Correction vectors are then used in practical shooting be taken into account.

Es ist daher Aufgabe der Erfindung,einen Gerätesatz und ein Verfahren zum Testen des dynamischen Verhaltens, insbesondere der Richtgenauigkeit, von Rohrwaffen unter Einsatzbedingungen anzugeben.It is therefore an object of the invention, a device set and a Methods for testing dynamic behavior, in particular the accuracy of pipe guns under operating conditions specify.

Die Lösung dieser Aufgabe erfolgt gemäß Anspruch 1 und Anspruch 6 mit einer Video-Kamera und einer Bildwiedergabeeirichtung. Die Video-Kamera ist vorzugweise mit Hilfe eines Adapters am oder im Rohr der Rohrwaffe derart befestigbar, daß die optische Achse der Video-Kamera sehr genau mit der Seelenachse des Rohrs übereinstimmt. Das Bild der Video-Kamera wird auf bekannte Weise, beispielsweise mit Hilfe eines entsprechenden Kabels, der Bildwiedergabeeinrichtung zugeführt und von dieser wiedergegeben. Die Bildwiedergabeeinrichtung ist als tragbarer oder in ein übliches Gestell einsetzbarer Gerätesatz ausgeführt.This object is achieved according to claim 1 and Claim 6 with a video camera and an image display device. The video camera is preferably with the help an adapter can be attached to or in the barrel of the barrel weapon in such a way that the optical axis of the video camera is very exactly matches the core axis of the tube. The Image of the video camera is made in a known manner, for example with the help of an appropriate cable, the image display device fed and reproduced by this. The image display device is as portable or device set that can be inserted into a conventional frame.

Bei einer bevorzugten Ausführung generiert die Bildwiedergabeeinrichtung ein Fadenkreuz oder Fehlerquadrat, das in das von der Video-Kamera gelieferte Bild eingeblendet und zusammen mit diesem wiedergegebenm wird.In a preferred embodiment, the image display device generates a crosshair or mistake square that in the image supplied by the video camera is displayed and is reproduced together with this.

In einer weiteren Ausführungsform ist das Testgerät auch zum Testen des dynamischen Verhaltens von Zwillingsgeschützen einsetzbar. Dazu enthält es eine weitere Video-Kamera, die in gleicher Weise wie die erste am oder im Rohr einer zweiten Rohrwaffe befestigbar ist. Die von den beiden Video-Kameras gelieferten Bilder werden in der Bildwiedergabeeinrichtung einander überlagert und gemeinsam wiedergegeben. Sofern beide Rohre genau auf dasselbe Ziel ausgerichtet sind, liefert die Bildwiedergabeeinrichtung ein scharfes Bild des Ziels. Eine nicht hinreichend übereinstimmende Ausrichtung der beiden Rohre ist an der Unschärfe des Bildes zu erkennen und anhand der geeichten Fadenkreuze exakt auszumessen.In a further embodiment, the test device is also to test the dynamic behavior of twin guns applicable. It also contains another video camera, the same as the first on or in Tube of a second gun is attachable. The one from the Images supplied in both video cameras are in the Image display device superimposed and common reproduced. Provided both pipes are aimed at exactly the same target are, the image display device provides a sharp image of the Target. An insufficiently consistent alignment of the Both tubes can be recognized by the blurriness of the picture and by the calibrated crosshairs to measure exactly.

An die Stabilisierungs- und Steuerungseinrichtungen eines auf einem mobilen Waffensystem installierten Geschützes werden unter Einsatzbedingungen extreme Anforderungen gestellt. Beispielsweise muß die Stabilisierungseinrichtung eines auf einem Schnellboot installierten Geschützes die Bewegungen des Schiffrumpfes ausgleichen, die dieser infolge des Seeganges oder aufgrund von Maschinenmanövern durchführt. Entsprechendes gilt für beispielsweise auf Panzern montierte Geschütze, deren Stabilisierungsanlage auch harte, durch Bodenunebenheiten ausgelöste Stöße ausgleichen muß. In beiden Fällen sorgt die Stabilisierungsanlage dafür, daß die Lage des Geschützrohres im Raum unverändert bleibt.To the stabilization and control devices one on one Mobile weapon system installed gun are under operating conditions extreme demands. For example, the Stabilization device of one installed on a speedboat Guns compensate for the movements of the hull that this due to the swell or due to machine maneuvers. The same applies to, for example, mounted on tanks Guns whose stabilization system is also hard, due to uneven floors compensated for impacts. In both cases the stabilization system ensures that the position of the gun barrel remains unchanged in the room.

Wird nun beispielsweise von der Radaranlage des Waffensystemes ein Ziel lokalisiert, so wird mittels einer Feuerleiteinrichtung die Lage des Geschützrohres im Raum ermittelt, die dieses zur Bekämpfung des Ziels einnehmen muß. Da bei mobilen Waffensystemen zur Bekämpfung beweglicher Ziele sich die relative Position des Ziels zum Geschütz laufend ändert, muß das Geschütz laufend nachgeführt werden.Now, for example, from the radar system of the weapon system The target is localized using a fire control system Location of the gun barrel in the room determined this to combat of the target. Because to combat mobile weapon systems moving targets the relative position of the target to If the gun changes continuously, the gun must be continuously updated become.

Üblicherweise liefert die Feuerleiteinrichtung Richtwerte, die die ballistischen Eigenschaften der Projektile sowie insbesondere die Windverhältnisse berücksichtigen. Dies hat zur Folge, daß die Seelenachse des Rohres und die optische Verbindungslinie zwischen Rohr und Ziel einen bestimmten Winkel zueinander aufweisen. Da das erfindungsgemäße Testgerät auf optischem Wege arbeitet, ist es nur zum Testen der Richtgenauigkeit von solchen Rohrwaffen geeignet, bei denen in der zugehörigen Feuerleiteinrichtung die Berücksichtigung des sogenannten Vorhaltes abgeschaltet werden kann. Ohne Berücksichtigung des Vorhaltes fällt nämlich die Seelenachse des Rohres mit der optischen Verbindungslinie zwischen Rohr und Ziel zusammen, d.h. beim Blick durch das Rohr ist das Ziel erkennbar.The fire control system usually provides guide values that the ballistic properties of the projectiles and in particular the Take wind conditions into account. As a result, the Axis of the tube and the optical connecting line between Pipe and target have a certain angle to each other. Since that Test device according to the invention works optically, it is only suitable for testing the accuracy of such guns, at those in the associated fire control system the so-called lead can be switched off. Without consideration The lead axis coincides with the lead the optical connection line between tube and target together, i.e. when looking through the pipe, the target is recognizable.

Zum Testen der Richtgenauigkeit einer Rohrwaffe wird gemäß einem bevorzugten Ausführungsbeispiel die Video-Kamera im Rohr der zu testenden Rohrwaffe befestigt. Dies geschieht mit Hilfe eines Adapters, dessen Außendurchmesser dem Kaliber des Rohres entspricht. Für unterschiedliche Kaliber sind demzufolge entsprechend verschiedene Adapter notwendig. Bei der Video-Kamera handelt es sich um eine Spezialausführung, deren optische Achse präzise gegenüber ihrem Gehäuse justiert ist. Auch der Adapter ist mit größter Präzision gefertigt. Dadurch wird eine genaue Ausrichtung der optischen Achse der Video-Kamera mit der Seelenachse des Rohres bei der Befestigung der Video-Kamera im Rohr erzielt.To test the accuracy of a barrel weapon according to a preferred embodiment, the video camera in the tube of the test gun attached. This is done with the help of a Adapters, whose outer diameter corresponds to the caliber of the pipe. For different calibers there are accordingly different ones Adapter required. The video camera is a Special design, the optical axis of which is precise in relation to yours Housing is adjusted. The adapter is also extremely precise manufactured. This will ensure precise alignment of the optical axis the video camera with the core axis of the tube when fastening the video camera in the tube.

Ist das Rohr genau aufs Ziel ausgerichtet, so erscheint das Bild des Ziels auf der Bildwiedergabeeinrichtung genau in Bildmitte. Zur besseren Erkennbarkeit etwaiger Abweichungen ist in das Bild ein Fadenkreuz oder ein Fehlerquadrat eingeblendet. Wenn alle Systeme des Waffensystems korrekt arbeiten, bleibt auch ein bewegtes Ziel und auch bei voller Fahrt des Waffensystems immer genau in Bildmitte bzw. innerhalb des Fehlerquadrats. Somit läßt sich durch bloßes Beobachten des durch die Bildanzeigeeinrichtung dargestellten Bildes des Ziels über einen gewissen Zeitraum hinweg eine Aussage über die Richtgenauigkeit der Rohrwaffe machen.If the pipe is exactly aligned with the target, the picture of the Target on the image display device exactly in the center of the image. For Any discrepancies can be seen better in the picture Crosshairs or a square of errors appear. If all systems of the weapon system working correctly remains a moving target and always in the center of the picture, even when the weapon system is in full swing or within the square of errors. Thus, by mere Observing the image represented by the image display device of the target over a certain period of time a statement about the Make accuracy of the barrel weapon.

Insbesondere beim Einsatz des Testgeräts auf Schiffen ist es vorteilhaft die Bildanzeigeeinrichtung beispielsweise in der Operationszentrale zu installieren. Die Video-Kamera kann dann beispielsweise nacheinander an den diversen Geschützen des Schiffes angebracht werden, um deren dynamisches Verhalten zu überprüfen. Die Bildübertragung von der Video-Kamera zur Bildanzeigeeinrichtung erfolgt vorzugsweise über ein sowieso vorhandenes Videokabelnetz, an das die Video-Kamera in der Nähe eines jeden Geschützes anschließbar ist.It is particularly advantageous when using the test device on ships the image display device, for example in the operations center to install. The video camera can then, for example attached to the various guns of the ship one after the other to check their dynamic behavior. The Image transmission from the video camera to the image display device preferably takes place via an existing video cable network that the video camera can be connected in the vicinity of each gun is.

Der Vorteil dieses Testgeräts besteht insbesondere darin, daß ohne nennenswerten Aufwand praktisch jederzeit, beispielsweise bei Instandsetzungen nach längerer Nichtbenutzung oder vor Schießübungen, eine eindeutige Aussage über die Richtgenauigkeit einer Rohrwaffe gemacht werden kann. Dadurch läßt sich beispielsweise Munition durch Vermeidung von Fehlschüssen einsparen, sowie Zeit und damit Kosten, wenn gegebenenfalls von vornherein die unnütze Anfahrt ins Schießgebiet entfällt. Ferner läßt sich, beispielsweise zu Ausbildungszwecken, die Funktion Rohrwaffe eindrucksvoll demonstrieren.The advantage of this test device is in particular that without significant effort practically at any time, for example at Repairs after long periods of non-use or before target practice, a clear statement about the accuracy of a barrel weapon can be made. This allows, for example, ammunition save by avoiding misses, as well as time and thus costs, if necessary, the useless approach from the outset into the shooting range. Furthermore, for example for training purposes, impressively demonstrate the function of the barrel weapon.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Es zeigt:

Der Adapter 4 ist so bemessen, daß sein Außendurchmesser dem Kaliber des Kanonenrohres 1 entspricht, also nur sehr geringfügig kleiner als der Innendurchmesser des Kanonenrohres 1 ist, so daß beim Einführen des Adapters 4 in das Rohr 1 auch ihre Rotationsachsen 3 zusammenfallen. Ein Randflansch 7 des Adapters 4 dient gleichermaßen als Anschlag- und Handgriff. Über weitere Verbindungsmittel, wie z. B. Klemmschrauben (nicht eingezeichnet) ist der Adapter 4 im Kanonenrohr 1 befestigbar. Durch diese Anordnung wird erreicht, daß die Rotationsachse 3 der Linsenanordnung 12 mit der Rotations- oder Seelenachse 3 des Kanonenrohres fluchtet.The cylindrical video camera 10 with a lens 12 is in a essential cylindrical adapter 4 with connecting means 5 Fastening webs 14 fixed by screws 16 so that the axes of rotation 3 of the adapter and the camera coincide. The Adapter 4 is dimensioned so that its outer diameter is the caliber of Gun barrel 1 corresponds, that is, only very slightly smaller than is the inside diameter of the gun barrel 1 so that when inserted of the adapter 4 in the tube 1 also their axes of rotation 3 coincide. An edge flange 7 of the adapter 4 also serves as Stop and handle. About other connecting means such. B. Clamping screws (not shown) is the adapter 4 in the gun barrel 1 attachable. This arrangement ensures that the Rotation axis 3 of the lens arrangement 12 with the rotation or Soul axis 3 of the gun barrel is aligned.

An der Vorderseite der Videokamera 10 werden optische Signale, welche die durch einen sich hinter der Linsenanordnung 12 befindlichen Halbleiterbildaufnehmer (nicht eingezeichnet) in elektrische Impulse umgeformt werden, über die Leitung 30 zu einem Monitor 20 geleitet. Auf dem Monitor 20 wird das Bild des Zieles zusammen mit einem für Einstell- und Meßarbeiten nützlichen Fadenkreuz 22 dargestellt. Ist das Kanonenrohr 1 genau auf das Ziel gerichtet, so erscheint dann das Bild des Ziels auf dem Monitor 20 genau in der Mitte des Fadenkreuzes 22.At the front of the video camera 10 optical signals, which is the one behind the lens arrangement 12 Semiconductor image sensor (not shown) in electrical Pulses are converted via line 30 to a monitor 20 headed. The image of the target is shown on the monitor 20 together with a crosshair 22 useful for setting and measuring work.
