Abstract

In a test device (1) for checking the bore sight and the parallelism between the sight lines of aiming devices (7) and the bore axes (17) of weapons (16) of a combat vehicle, there is arranged at a short distance in front of the combat vehicle at least one optical triple element (5) which has three reflecting surfaces (6, 7, 8) arranged respectively at right angles to one another. In this way, a target beam which enters the triple element at any solid angle and which is generated, for example, by a collimator (15) arranged in the muzzle of a weapon can be reflected with an exact parallel offset and be guided into the beam path of an aiming device, in which possible adjustment deviations can be checked. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Prüfvorrichtung für ein Waffensystem gemäß dem Oberbegriff des Patentanspruchs 1. Eine derartige Prüfvorrichtung ist aus der GB-A-1 965 (A.D. 1909) bekannt.The invention relates to a test device for a weapon system according to the preamble of claim 1. Such a test device is known from GB-A-1 965 (A.D. 1909).

Bei einer aus der DE-C2-3 246 805 bekannten Prüfvorrichtung werden die Instrumente der Feuerleitanlage eines Kampffahrzeugs, die jeweils eine auf Zielpunkte richtbare Ziellinie aufweisen, mittels einer in kurzem Abstand vor dem Kampffahrzeug aufstellbaren Hohlspiegeleinrichtung, einer im Brennpunkt der Hohlspiegeleinrichtung angeordneten Bildflächeneinrichtung und einer Strahlenquelle überprüft einer Waffe adaptierbar ist und mit der mit parallelen, mit der Seelenachse zusammenliegenden Strahlen im Unendlichen ein Punkt abbildbar ist. Die parallelen Strahlen werden nach Reflexion an der Hohlspiegeleinrichtung auf der Bildflächeneinrichtung als Punkt abgebildet, der von den einzelnen Instrumenten, beispielsweise dem Richtschützenperiskop und dem Kommandantenperiskop betrachtet werden kann, deren Ziellinien in gleicher Weise nach Reflexion an der Hohlspiegeleinrichtung auf die Bildflächeneinrichtung auftreffen. Diese Justiervorrichtung ist aufwendig, da die Hohlspiegeleinrichtung zum einen große Abmessungen aufweist, damit sämtliche parallel gerichteten Zielstrahlen erfaßt werden können und zum anderen eine sehr große Genauigkeit erfordert, um die Zielstrahlen bzw. die Strahlen der in der Waffe angeordneten Strahlenquelle präzise im Brennpunkt auf dem Bildflächenelement zu fokussieren.In a test device known from DE-C2-3 246 805, the instruments of the fire control system of a combat vehicle, each having a target line that can be aimed at, are positioned by means of a concave mirror device that can be set up at a short distance in front of the combat vehicle, an image area device arranged in the focal point of the concave mirror device and one Radiation source checked for a weapon is adaptable and with which a point can be imaged with parallel rays that lie together with the axis of the soul at infinity. After reflection at the concave mirror device, the parallel rays are imaged on the image area device as a point that can be viewed by the individual instruments, for example the gunner's periscope and the commander's periscope, the target lines of which strike the image area device in the same way after reflection at the concave mirror device. This adjustment device is complex, since the concave mirror device has large dimensions, on the one hand, so that all parallel aimed beams can be detected and, on the other hand, requires a very high degree of accuracy in order to precisely target the beams or the beams of the radiation source arranged in the weapon at the focal point on the screen element to focus.

Aus der eingangs erwähnten GB-A-1 965 (A.D. 1909) ist es bereits bei einer Prüfvorrichtung für die Ziellinie eines Gewehrs bekannt, als Ablenkelemente ein Tripelprisma und ein Rhomboidprisma zu verwenden, die in zwei gelenkig miteinander verbundenen Längsarmen so gelagert sind, daß sich ihre Strahleneintritts- und -austrittsbereiche überlappen.From the aforementioned GB-A-1 965 (AD 1909) it is already known in a test device for the target line of a rifle to use a triple prism and a rhomboid prism as deflecting elements, which are mounted in two articulated longitudinal arms so that their radiation entry and exit areas overlap.

Aus der EP-A-0 189 001 ist eine Prüfvorrichtung bekannt, welche ein einziges, in einem Gehäuse eingebautes Tripelprisma aufweist.A test device is known from EP-A-0 189 001, which has a single triple prism installed in a housing.

Die Aufgabe der Erfindung besteht demgegenüber darin, eine Prüfvorrichtung der eingangs erwähnten Art zu schaffen, welche auch für Kampffahrzeuge verwendbar ist und gegenüber bislang für Kampffahrzeuge verwendbaren Prüfvorrichtungen einen geringeren gerätetechnischen Aufwand bei leichterer Handhabbarkeit und höherer Meßgenauigkeit aufweist.In contrast, the object of the invention is to provide a test device of the type mentioned at the outset, which can also be used for combat vehicles and, compared to test devices previously used for combat vehicles, has a lower outlay in terms of technical equipment with easier handling and higher measuring accuracy.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Durch die erfindungsgemäße Aneinanderkopplung der Ein- und Ausgänge mehrerer Tripelelemente in jeweils einem der beiden Längsarme ergibt sich ein mäanderförmiger Strahlengang, der eine nahezu beliebige Parallelversetzung des eintretenden zum austretenden Strahl zuläßt. Ein besonderer Vorteil ist dadurch gegeben, daß eventuelle Ungenauigkeiten in der Zuordnung der Tripelelemente, z.B. ein Winkelversatz zwischen zwei benachbarten Tripelelementen, keinerlei Auswirkungen auf die Genauigkeit der Parallelitätsüberprüfung haben. Die Genauigkeit hängt allein von der Fertigungsgenauigkeit der einzelnen Prismen ab. Danmit ist auch die Stabilität der Halterung der Tripelelemente vollkommen unbedeutend.The inventive coupling of the inputs and outputs of several triple elements in each of the two longitudinal arms results in a meandering beam path which allows almost any parallel displacement of the incoming and outgoing beams. A particular advantage is that possible inaccuracies in the assignment of the triple elements, for example an angular offset between two adjacent triple elements, have no effect on the accuracy of the parallelism check. The accuracy depends solely on the manufacturing accuracy of the individual prisms. The stability of the mounting of the triple elements is also completely insignificant.

In einer besonders bevorzugten Ausführungsform werden die Tripelelmente jeweils nur im Randbereich ausgenutzt. Das Tripelelemente kann daher in der Höhe bzw. parallel zur Fläche des Strahleneingangs sowie des Strahlenausgangsbereiches und zu beiden Seiten, im Parallelabstand zu einer Schnittkante zweier Reflexionsflächen des Tripelelementes abgeschnitten sein. Neben der Baugröße wird damit auch das Gewicht der Gesamtanordnung reduziert.In a particularly preferred embodiment, the triple elements are only used in the edge area. The triple element can therefore be cut off in height or parallel to the surface of the beam entrance and the beam exit region and on both sides, at a parallel distance to a cut edge of two reflection surfaces of the triple element. In addition to the size, the weight of the overall arrangement is also reduced.

Zweckmäßigerweise sind die Tripelelemente in Längsarmen angeordnet, wobei es besonders vorteilhaft ist, zwei Längsarme über ein Drehgelenk zu koppeln. Damit läßt sich die Vorrichtung auf jeden beliebigen Parallelabstand einstellen. Das Gelenk liegt dabei an der Kopplungsstelle zwischen zwei Tripelelementen und kann die Strahlrichtung in keiner Weise beeinflussen. Eine Winkeländerung des Gelenkes ist auch auf die Bildaufrichtung ohne Einfluß, so daß ein über die in den Längsarmen angeordneten Tripelelemente übertragenes Bild keine zusätzliche Drehung erfährt. Bei geradzahliger Anzahl der Tripelelemente bleibt die Bildlage vom Eingang zum Ausgang erhalten, bei ungeradzahliger Anzahl wird das Bild seitenund höhenvertauscht. Um den in die Prüfvorrichtung eintretenden Strahl wieder auf das Prüfobjekt zu reflektieren ist eine ungerade Anzahl von Tripelelementen erforderlich. Aus diesem Grund ist in einem Längsarm ein Tripelelment mehr angeordnet als im anderen Längsarm.The triple elements are expediently arranged in longitudinal arms, it being particularly advantageous to couple two longitudinal arms via a swivel joint. This allows the device to be set to any parallel distance. The joint lies at the coupling point between two triple elements and cannot influence the beam direction in any way. A change in the angle of the joint also has no influence on the image erection, so that an image transmitted via the triple elements arranged in the longitudinal arms does not undergo any additional rotation. If the number of triple elements is even, the position of the image from the entrance to the exit is retained, and if the number is odd, the image is exchanged for sides and heights. In order to reflect the beam entering the test device back onto the test object, an odd number of triple elements is required. For this reason, one more triple element is arranged in one longitudinal arm than in the other longitudinal arm.

Da die Gesamtgenauigkeit der Prüfvorrichtung nur von der Fertigungsgenauigkeit der einzelnen Tripelelemente abhängt, ist es vorteilhaft, in den Strahlengang des Prüfgerätes zwischen zwei Tripelelementen ein Korrekturelement einzufügen, wodurch sich eine extreme Genauigkeit bei der Herstellung der Tripelelemente erübrigt. Das Korrekturelement ermöglicht eine Korrektur der Strahleneinrichtung entsprechend der Summe aller Einzelfehler der Tripelelemente, so daß der Gesamtfehler auf Null reduzierbar ist.Since the overall accuracy of the testing device depends only on the manufacturing accuracy of the individual triple elements, it is advantageous to insert a correction element in the beam path of the testing device between two triple elements, which eliminates the need for extreme accuracy in the production of the triple elements. The correction element enables the radiation device to be corrected in accordance with the sum of all individual errors of the triple elements, so that the total error can be reduced to zero.

In einer vorteilhaften Ausführungsform besteht das Korrekturelement aus gegeneinander verdrehbaren optischen Keilscheiben.In an advantageous embodiment, the correction element consists of optical wedge disks which can be rotated relative to one another.

Weitere Vorteile ergeben sich aus der nachfolgenden Beschreibung anhand der Zeichnung und in Verbindung mit den Ansprüchen.Further advantages result from the following description with reference to the drawing and in connection with the claims.

It shows

Fig. 2
1 in the self-test position.

Die Figur 1 zeigt die Prüfvorrichtung 1, die sich aus zwei Längsarmen 2 und 3 zusammensetzt, die über ein Gelenk 4 miteinander verbunden sind. Die Längsarme 2 und 3 tragen jeweils eine Anzahl von Tripelelementen 5, von denen jedes drei im rechten Winkel zueinander stehende Reflexionsflächen 6, 7 und 8 aufweist. Die Reflexionsflächen können in optischen Tripelprismen oder Tripelspiegeln enthalten sein. Die geometrische Formgebung eines Tripelelementes ist im genaueren anhand der Fig. 4 bis 7 beschrieben. Jedes Tripelelement 5 enthält einen Strahleneingangsbereich 9 und einen Strahlenausgangsbereich 10, wobei die Tripelelemente 5 in den Längsarmen 2 und 3 jeweils so zueinander angeordnet sind daß dem Strahlenausgangsbereich 10 der Strahleneingangsbereich 9 des nachgeordneten Tripelelementes 5 gegenüber liegt.FIG. 1 shows the test device 1, which is composed of two longitudinal arms 2 and 3, which are connected to one another via a joint 4. The longitudinal arms 2 and 3 each carry a number of triple elements 5, each of which has three reflection surfaces 6, 7 and 8 which are at right angles to one another. The reflection surfaces can be contained in optical triple prisms or triple mirrors. The geometric shape of a triple element is described in more detail with reference to FIGS. 4 to 7. Each triple element 5 contains a radiation input region 9 and a radiation output region 10, the triple elements 5 in the longitudinal arms 2 and 3 each being arranged in such a way that the radiation output region 10 is opposite the radiation input region 9 of the downstream triple element 5.

Das Gelenk 4 weist einen freien Strahlendurchgang auf, in dem ein Korrekturelement 11 angeordnet ist, das gegeneinander verdrehbare optische Keilscheiben aufweist.The joint 4 has a free beam passage in which a correction element 11 is arranged, which has optical wedge disks that can be rotated relative to one another.

An den Enden weisen die Längsarme 2 und 3 Fensteröffnungen 12 und 13 auf.The longitudinal arms 2 and 3 have window openings 12 and 13 at the ends.

Die die Tripelelemente 5 in den Längsarmen 2 und 3 durchlaufende Ziellinie 14 wird von einer aus einem Spiegelkollimator bestehenden Strahlenquelle 15 erzeugt, die in präziser Fixierung in der Mündung einer Waffe 16 bzw. Kanone derart befestigt ist, daß die Seelenachse 17 der Kanone mit der von der Strahlenquelle 15 erzeugten Ziellinie 14 zusammenfällt.The target line 14 passing through the triple elements 5 in the longitudinal arms 2 and 3 is generated by a radiation source 15 consisting of a mirror collimator, which is fixed in a precise fixation in the muzzle of a weapon 16 or cannon such that the soul axis 17 of the cannon is aligned with that of of the radiation source 15 generated target line 14 coincides.

In der Strahlenquelle 15 ist ein Strichmarkenträger 18 (Fig. 2) angeordnet, mittels dem über die in den Strahlengang des Kommandantenperiskops 17 eintretende Ziellinie 14 eine die Justierstellung der Waffe 16 repräsentierende Strichmarke 19 im Okular 20 des Kommandantenperiskops 17 darstellbar ist. Eine eventuelle Ablage der Strichmarke 19 von der Visiermarkierung 21 des Kommandantenperiskops 17 zeigt somit die zu korrigierende Justierabweichung zwischen der Ziellinie der Kanone und der Visierlinie des Kommandantenperiskops an.Arranged in the radiation source 15 is a line mark carrier 18 (FIG. 2), by means of which a line mark 19 representing the adjustment position of the weapon 16 in the eyepiece 20 of the commandant periscope 17 can be represented via the target line 14 entering the beam path of the commander periscope 17. A possible deposit of the line mark 19 from the sighting mark 21 of the commander's periscope 17 thus indicates the adjustment deviation to be corrected between the target line of the cannon and the sighting line of the commander's periscope.

In gleicher Weise erfolgt die Überprüfung der Justierstellung in bezug auf das Richtschützenperiskop 22, wobei die Ziellinie 14 durch einfaches Verschwenken der Längsarme 2 und 3 um die Achse 4' des Gelenks 4 auf den Strahlengang des Richtschützenperiskops ausgerichtet werden kann.The adjustment position is checked in the same way with respect to the gunner's periscope 22, the target line 14 being able to be aligned with the beam path of the gunner's periscope by simply pivoting the longitudinal arms 2 and 3 about the axis 4 'of the joint 4.

Aufgrund der Verwendung eines Spiegelkollimators als Strahlenquelle 15 kann neben dem sichtbaren Wellenlängenbereich auch im Infrarot-Wellen-längenbereich z.B. 10 - Bereich emittiert werden, wodurch die Strichmarke 19 auch im Wärmebildgerät 23 abbildbar ist.Due to the use of a mirror collimator as the radiation source 15, in addition to the visible wavelength range, also in the infrared wavelength range e.g. 10 - area are emitted, whereby the line mark 19 can also be imaged in the thermal imaging device 23.

Zur Überprüfung des Lasersenders 24 wird die Fensteröffnung 13 in den Sendestrahl 25 des Lasersenders 24 und die Fensteröffnung 12 in den Strahlengang der Strahlenquelle 15 geschwenkt, wobei anstelle des Strichmarkenträgers 18 eine strahlungsempfindliche Platte eingeschwenkt wird, mit der die Strahlung des Lasersenders 24 sichtbar gemacht werden kann. Besonders sind hierfür mit phosphoreszierendem Material beschichtete Platten geeignet, da sie wiederverwendbar sind. Der Strichmarkenträger 18 und die strahlungempfindliche Platte sind dabei so angeordnet, daß sie je nach Bedarf in den Strahlengang der Strahlungsquelle 15 eingeschwenkt werden können. Die Lichtenergie des Lasers 24 wird über die Prüfvorrichtung zur Strahlungsquelle 15 gelenkt und erzeugt dort auf der strahlungsempfindlichen Platte einen nachleuchtenden Punkt ab. Die Winkellage dieses Punktes zu einem Periskop, beispielsweise dem Kommandantenperiskop 17 kann anschließend sichtbar gemacht werden, indem die Fensteröffnung 13 aus dem Sendestrahl 25 des Lasersenders 24 in den Strahlengang des Kommandantenperiskops 17 geschwenkt wird. Eine eventuelle Ablage des nachleuchtenden Punktes von der Visiermarkierung 21 des Kommandantenperiskops 17 zeigt die zu korrigierende Justierabweichung des Lasersenders 24 von dem vorher bereits justierten Kommandantenperiskops 17 an.To check the laser transmitter 24, the window opening 13 is pivoted into the transmission beam 25 of the laser transmitter 24 and the window opening 12 into the beam path of the radiation source 15, a radiation-sensitive plate being pivoted in instead of the line mark carrier 18 with which the radiation from the laser transmitter 24 can be made visible. Panels coated with phosphorescent material are particularly suitable for this purpose, since they are reusable. The line mark carrier 18 and the radiation-sensitive plate are arranged so that they can be pivoted into the beam path of the radiation source 15 as required. The light energy of the laser 24 is directed to the radiation source 15 via the test device and there produces an afterglow point on the radiation-sensitive plate. The angular position of this point relative to a periscope, for example the commander's periscope 17, can then be made visible by pivoting the window opening 13 out of the transmission beam 25 of the laser transmitter 24 into the beam path of the commander's periscope 17. A possible deposit of the afterglow point from the sighting mark 21 of the commandant's periscope 17 indicates the adjustment deviation of the laser transmitter 24 to be corrected from the commandant's periscope 17 which has already been adjusted.

Die Fig. 2 zeigt die Prüfvorrichtung 1 in der Selbstteststellung in dem eine Überprüfung der Parallelität des eintretenden und des austretenden Strahls durchgeführt werden kann. Dies erfolgt dadurch, daß der Längsarm 3 parallel zum Längsarm 2 geklappt wird, so daß die in die Prufvorrichtung 1 eintretende Ziellinie 14' als auch die von der Prüfvorrichtung 1 austretende Ziellinie 14" von einer in der Strahlenquelle 15 angeordneten Beobachtungsvorrichtung betrachtet werden kann. Um dies trotz der unterschiedlichen Anzahl der Tripelelemente 5 zu ermöglichen, werden die Tripelelemente 5 im Längsarm 3 entsprechend länger ausgeführt.2 shows the test device 1 in the self-test position in which a check of the parallelism of the entering and exiting beam can be carried out. This is done in that the longitudinal arm 3 is folded parallel to the longitudinal arm 2, so that the target line 14 'entering the testing device 1 and the finishing line 14 "emerging from the testing device 1 can be viewed by an observation device arranged in the radiation source 15 to enable this despite the different number of triple elements 5, the triple elements 5 in the longitudinal arm 3 are made correspondingly longer.

Die erste Reflexionsfläche 6 an der Fensteröffnung 12 des ersten Längsarmes 2 ist als halbdurchlässiger Spiegel, z.B. teilverspiegelter Spiegel (sowohl für sichtbares als auch für IR-Licht) ausgeführt. Dadurch kann der aus der Strahlenquelle 15 austretende Strahl (Ziellinie 14') wieder in die Strahlenquelle 15 als reflektierter Strahl (Ziellinie 14") zurückgeführt werden und die Parallelität beider Strahlen überprüft werden. Dies geschieht mittels eines in der Strahlenquelle 15 bzw. im Spiegelkollimator angeordneten Strahlenteilers 26 durch den im Okular 27 zum einen die von einem Strichmarkenträger 18 erzeugte Strichmarke 19 der aus der Strahlenquelle 15 austretenden Ziellinie 14' und zum anderen die Strichmarke 19' der reflektierten Ziellinie 14" abbildbar ist. Eine eventuelle Ablage der reflektierten Strichmarke 19' von der Strichmarke 19 zeigt die Ungenauigkeit der Prüfvorrichtung 1 an, die über das Korrekturelement 11 beseitigt werden kann.The first reflection surface 6 at the window opening 12 of the first longitudinal arm 2 is designed as a semitransparent mirror, for example a partially mirrored mirror (both for visible and for IR light). As a result, the beam emerging from the radiation source 15 (target line 14 ′) can be returned to the radiation source 15 as a reflected beam (target line 14 ″) and the parallelism of both beams can be checked will. This is done by means of a beam splitter 26 arranged in the radiation source 15 or in the mirror collimator, through which in the eyepiece 27 on the one hand the line mark 19 'of the target line 14' emerging from the radiation source 15 and on the other hand the line mark 19 'of the reflected target line 14 Any deposition of the reflected line mark 19 'from the line mark 19 indicates the inaccuracy of the test device 1, which can be eliminated via the correction element 11.

Zur Gleichlaufprüfung wird die Prüfvorrichtung 1 über ein entsprechendes Adaptionsteil (nicht dargestellt) an der Waffe 16 befestigt. In diesem Adaptionsteil ist eine seiten- und höhenrichtbare Halterung für den Spiegelkollimator integriert. Dieser ist unmittelbar vor dem optischen Eingang der Prüfvorrichtung angeordnet, so daß nach dem Schwenken der Prüfvorrichtung in die Sichtlinie des Zielgerätes die Strichmarke des Spiegelkollimators im Okular des Zielgerätes erscheint.For the synchronism test, the test device 1 is attached to the weapon 16 by means of a corresponding adaptation part (not shown). A side and height adjustable bracket for the mirror collimator is integrated in this adaptation part. This is arranged immediately in front of the optical input of the test device, so that after the pivoting of the test device into the line of sight of the target device, the line mark of the mirror collimator appears in the eyepiece of the target device.

Nach dem Justieren des Spieglekollimators auf das Fadenkreuz des Zielgerätes kann die eigentliche Gleichlaufprüfung durchgeführt werden:After adjusting the mirror collimator on the crosshair of the target device, the actual synchronization test can be carried out:

Einstellen des gewünschten Elevationswinkels, ggf. Nachführen der Prüfvorrichtung und Ablesen der Abweichung in Seite und Höhe anhand der StrichmarkeSetting the desired elevation angle, if necessary tracking the test device and reading the deviation in side and height using the line mark

Die Gleichlaufprüfung von niçhtoptischen Zielgeräten erfordert wie bei der Justierüberprüfung ein separates Fernrohr welches am zu prüfenden elevierbaren Gerät angebracht wird.The synchronism check of non-optical target devices requires, as with the adjustment check, a separate telescope which is attached to the elevatable device to be tested.
