Abstract

The invention relates to a method and a device for the correction of dynamic gun errors. Dynamic gun errors are caused by the movement of a gun tube muzzle area (3) of a gun (1) in the course of continuous firing. To correct these errors, a measurement of the movement of a gun tube muzzle area (3) of a gun (1) is performed during continuous firing for obtaining measured signals. The measured signals are used for correcting the azimuth and elevation of the gun tube (2) in order to compensate the movement of a gun tube muzzle area (3).

Nach dem erfindungsgemässen Verfahren findet während eines Seriefeuers eine Messung der Bewegung des Mündungsbereichs des Waffenrohres, kurz des Waffenrohr-Mündungsbereiches, statt. Die hierbei gewonnenen Messsignale werden verwertet, um eine Korrektur der ursprünglichen Richtung des Waffenrohres durchzuführen, bzw. um die Stellung des Waffenrohres, das heisst seine Elevation und sein Azimut, so zu verändern, dass die Bewegung des Waffenrohr-Mündungsbereiches kompensiert wird. Auf diese Weise können Schussabgangsfehler vermieden werden.According to the method according to the invention, a measurement is made during a series fire the movement of the muzzle region of the weapon barrel, in short the weapon barrel muzzle region, instead of. The measurement signals obtained in this way are used for a correction to carry out the original direction of the weapon barrel, or to the position of the Gun barrel, that is, its elevation and azimuth, to change the movement the weapon barrel muzzle area is compensated. That way you can Mistakes in firing can be avoided.

Zur Durchführung dieses Verfahrens ist am Waffenrohr im Waffenrohr-Mündungsbereich eine Winkelmesseinrichtung angeordnet, welche zwei Messglieder aufweist, die in einer Ebene quer zur Längsachse des Waffenrohres um 90° zueinander versetzt sind.To carry out this procedure is on the gun barrel in the gun barrel muzzle area an angle measuring device is arranged, which has two measuring elements in one The plane is offset by 90 ° to one another transversely to the longitudinal axis of the weapon barrel.

Insbesondere in einer besonders vorteilhaften Ausbildung der Erfindung ist die Winkelmesseinrichtung durch zwei Messglieder gebildet, von denen jedes einen Faserkreisel aufweist. Kurz vor der Auslösung des Seriefeuers werden die Faserkreiselwinkel mit den Coderwinkeln des Geschützes abgeglichen. Während des Seriefeuers erfolgt die Messung der Bewegung des Waffenrohr-Mündungsbereiches, indem die Abweichungen der gemessenen Faserkreiselwinkel von den Coderwinkeln laufend festgestellt werden. Gemessen werden somit Abweichungen der Richtung der Waffenrohr-Mündung von der ursprünglich bestimmten und eingestellten Soll-Richtung. Die so gewonnenen Messsignale werden, nachdem sie Umrechnungen unterzogen wurden, zur Regelung der Antriebe verwendet, welche zum Richten des Waffenrohres vorgesehen sind.The angle measuring device is in particular in a particularly advantageous embodiment of the invention formed by two measuring elements, each of which has a fiber gyroscope.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispieles im Zusammenhang mit der Zeichnung erläutert. Es zeigen:

The invention is explained below using an exemplary embodiment in conjunction with the drawing. Show it:

In der Fig. 1 ist ein insbesondere für schnelles Seriefeuer geeignetes Geschütz 1 dargestellt. Im Bereich einer Waffenrohr-Mündung 3 eines Waffenrohres 2 des Geschützes 1 ist eine Messvorrichtung, umfassend ein erstes Messglied 4 und ein zweites Messglied 5, angeordnet, welche in einer Ebene senkrecht zur Längsachse des Waffenrohres 2 des Geschützes 1 um 90° zueinander versetzt sind. Eine Versetzung von 90° ist besonders vorteilhaft, aber es sind auch Versetzungen um kleinere Winkel als 90° möglich. Im weiteren ist es zwar besonders vorteilhaft aber nicht zwingend, die Messglieder 4, 5 in Richtung der Längsachse des Waffenrohres 2 nicht gegen einander zu versetzen. 1 shows a gun 1 which is particularly suitable for rapid series fire. In the area of a weapon barrel muzzle 3 of a weapon barrel 2 of the gun 1 there is a measuring device comprising a first measuring member 4 and a second measuring member 5 , which are offset by 90 ° to one another in a plane perpendicular to the longitudinal axis of the gun barrel 2 of the gun 1 . An offset of 90 ° is particularly advantageous, but an offset of less than 90 ° is also possible. Furthermore, it is particularly advantageous but not imperative not to move the measuring elements 4 , 5 against one another in the direction of the longitudinal axis of the weapon barrel 2 .

Das erste Messglied 4 ist einem Antrieb für die Schwenkung des Waffenrohres 2 zur Einstellung der Elevation und das zweite Messglied 5 einem Antrieb für die Schwenkung des Waffenrohres 2 zur Einstellung des Azimuts zugeordnet; hierbei handelt es sich um die Antriebe, die ohnehin an solchen Geschützen zum Richten des Waffenrohres in Elevation λ und Azimut α vorhanden sind und die daher nicht näher dargestellt und beschrieben sind.The first measuring element 4 is assigned to a drive for pivoting the weapon barrel 2 for adjusting the elevation and the second measuring element 5 is assigned to a drive for pivoting the weapon barrel 2 for adjusting the azimuth; these are the drives which are already present on such guns for aiming the weapon barrel in elevation λ and azimuth α and which are therefore not shown and described in more detail.

Die Messglieder 4 und 5 haben den Zweck, die Bewegung der Mündung des Waffenrohres 2 während eines Seriefeuers zu erfassen und in elektrische Messsignale bzw. Ausgangssignale umzuwandeln. Jedes der Messglieder 4, 5 weist einen Faserkreisel auf, der nach dem Messprinzip der Kreiselmessung arbeitet.The measuring elements 4 and 5 have the purpose of detecting the movement of the muzzle of the weapon barrel 2 during a series fire and converting it into electrical measuring signals or output signals. Each of the measuring elements 4, 5 has a fiber gyroscope that works according to the gyro measurement principle.

Ein Faserkreisel besteht im Wesentlichen aus einem Ring-Interferometer, in dem von einem Laser erzeugte Strahlen entgegengesetzt umlaufen und miteinander interferieren, wobei der Ring für den Strahlenverlauf aus einer Anzahl von Windungen einer Glasfaseranordnung gebildet wird, in welche der vom Laser erzeugte Strahl eingekoppelt wird. Wenn ein solches Ring-Interferometer um eine Achse rechtwinklig zur Ebene des Strahlenganges angeordnet wird, so tritt, wie vom Sagnac-Versuch her bekannt, ein Wegunterschied der gegenläufigen vom Laser emittierten Strahlen und damit eine Verschiebung der von diesen erzeugten Interferenzstreifen bzw. eine Änderung des Interferenzmusters ein. Diese Änderungen des Interferenzmusters werden von einem Detektor erfasst und als Ausgangssignale in Form von Drehraten bzw. Winkeländerungen abgegeben. In anderen Ausbildungen von Faserkreiseln wird der sich zwischen den gegenläufigen Strahlen einstellende Doppler-Effekt zur Ermittlung der Winkeländerungen benutzt.A fiber gyro essentially consists of a ring interferometer, in which one The laser generated rays circulate in opposite directions and interfere with each other, whereby the Ring for the beam path from a number of turns of an optical fiber arrangement is formed, into which the beam generated by the laser is coupled. If such Ring interferometer arranged around an axis perpendicular to the plane of the beam path If, as is known from the Sagnac experiment, there is a path difference from the opposite beams emitted by the laser and thus a shift in the interference fringes generated by them or a change in the interference pattern. These changes of Interference patterns are detected by a detector and output signals in the form of Turning rates or changes in angle given. In other designs of fiber gyros the Doppler effect between the opposing beams is used to determine who uses angle changes.

Der Resolver 12 ist an einem zweiten Eingang e2 der Regelungseinheit 10 angeschlossen, und der Encoder 16 ist an einem dritten Eingang e3 der Regelungseinheit 10 angeschlossen. Über einen vierten Eingang e4 und einen fünften Eingang e5 werden der Regelungseinheit 10 eine Referenz-Geschwindigkeit bzw. eine Referenz-Position zugeführt.The measuring device is connected to a control device. 2 , the measuring element 4 is connected to a first input e1 of a first control unit 10 . The control unit 10 is connected on the output side via lines R, S, T to a motor 11 of the one drive, namely that for pivoting the weapon barrel 2 in the vertical direction or for adjusting the elevation. The motor 11 is directly connected to a resolver 12 , further via a planetary gear 13 with a load 14 , which corresponds to the parts of the gun 1 to be moved, and further via a measuring gear 15 with an encoder 16 .

Im Schiessbetrieb werden die Drehraten des Messgliedes 4, vom Resolver 12 erzeugte Informationen über die aktuelle Position des Rotors des Motors 11, vom Encoder 16 erzeugte Informationen über die aktuelle Position einer Wiege bzw. Laffette des Geschützes 1, die Referenz-Geschwindigkeit sowie die Referenz-Position in der Regelungseinheit 10 derart verarbeitet, dass die Drehzahl des Motors 11 entsprechend der via die Leitungen R, S, T eingegebenen Informationen geändert und so die Stellung des Waffenrohres 2 beeinflusst und damit die Bewegung der Waffenrohr-Mündung 2 kompensiert werden kann.In shooting operation, the rotation rates of the measuring element 4 , information generated by the resolver 12 about the current position of the rotor of the motor 11 , information generated by the encoder 16 about the current position of a cradle or carriage of the gun 1, the reference speed and the reference Position in the control unit 10 processed in such a way that the speed of the motor 11 changes in accordance with the information entered via the lines R , S , T and thus influences the position of the weapon barrel 2 and thus the movement of the weapon barrel mouth 2 can be compensated.

Der weitere Antrieb, der für die Schwenkung des Waffenrohres 2 zur Einstellung des Azimuts vorgesehen ist, wird mittels einer weiteren, nicht dargestellten Regelungseinrichtung gesteuert, die der mit Bezug auf Fig. 2 beschriebenen Regelungseinheit 10 ähnlich ist.The further drive, which is provided for pivoting the weapon barrel 2 to adjust the azimuth, is controlled by means of a further control device, not shown, which is similar to the control unit 10 described with reference to FIG. 2 .

Kurz vor Auslösung des Seriefeuers des Geschützes 1 werden Faserkreiselwinkel der Messglieder 4 und 5 mit den Coderwinkeln des Geschützes 1 abgeglichen. Während des Seriefeuers werden die Abweichungen der Faserkreiselwinkel von den Coderwinkeln in der Regelungseinheit 10 ausgewertet und zur Regelung der Antriebe für die Schwenkungen des Waffenrohres 2 verwendet.Shortly before the series fire of the gun 1 is triggered, the gyro angles of the measuring elements 4 and 5 are compared with the encoder angles of the gun 1 . During the series fire, the deviations of the fiber gyro angles from the encoder angles are evaluated in the control unit 10 and used to control the drives for the pivoting of the weapon barrel 2 .
