Description

Die Erfindung betrifft ein drallstabilisiertes Artillerieprojektil gemäß dem Oberbegriff des Anspruches 1.The invention relates to a spin stabilized artillery projectile according to the preamble of claim 1.

Ein derartiges drallstabilisiertes Artillerieprojektil ist aus der DE 101 43 312 C1 und aus DE 102 42 588 B4 bekannt. Dieses Artillerieprojektil weist in seiner Ogive eine radial anstellende Bremseinrichtung auf, die zur Reduktion der Längsablage des Artillerieprojektiles in einem Zielgebiet dient. Damit ist eine 1 D-Korrektur möglich.Such a spin stabilized artillery projectile is from the DE 101 43 312 C1 and from DE 102 42 588 B4 known. This artillery projectile has in its ogive a radially acting braking device, which serves to reduce the longitudinal shelf of the artillery projectile in a target area. This makes a 1D correction possible.

Die Ablagefläche eines Artillerieprojektiles in einem Zielgebiet ist ellipsenförmig, sie weist also eine Längsachse und eine dazu orthogonale Querachse auf. Die Längsachse, d.h. die Längsablage, ist größer als die Querachse, d.h. die Querablage. Die Bremseinrichtung des bekannten drallstabilisierten Artillerieprojektiles dient dazu, die im Vergleich zur Querablage große Längsablage des Artillerieprojektiles im Zielgebiet zu reduzieren und somit die Zielgenauigkeit entsprechend zu verbessern.The storage area of an artillery projectile in a target area is elliptical, so it has a longitudinal axis and a transverse axis orthogonal thereto. The longitudinal axis, i. the longitudinal tray is larger than the transverse axis, i. the cross shelf. The braking device of the known spin-stabilized artillery projectile serves to reduce the large lengthwise deposit of the artillery projectile in the target area compared to the crossbeam and thus to improve the accuracy of the target accordingly.

Der Erfindung liegt die Aufgabe zugrunde, ein drallstabilisiertes Artillerieprojektil der eingangs genannten Art zu schaffen, bei dem mit einfachen Mitteln auch die Querablage des Artillerieprojektiles im Zielgebiet reduziert und somit die Zielgenauigkeit entsprechend verbessert ist.The invention has for its object to provide a spin stabilized artillery projectile of the type mentioned, in which reduced by simple means and the cross-placement of the artillery projectile in the target area and thus the accuracy is improved accordingly.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst. Bevorzugte Aus- bzw. Weiterbildungen des erfindungsgemäßen bahnkorrigierenden drallstabilisierten Artillerieprojektiles sind in den Unteransprüchen gekennzeichnet.This object is achieved by the features of claim 1. Preferred embodiments or further developments of the sheet-correcting spin-stabilized artillery projectile according to the invention are characterized in the subclaims.

Dadurch, dass bei dem erfindungsgemäßen drallstabilisierten Artillerieprojektil am Umfang verteilt eine Anzahl Impulselemente vorgesehen sind, ist es möglich, durch passende Aktivierung mindestens eines entsprechenden Impulselementes eine Reduktion der Querablage des Artillerieprojektiles im Zielgebiet zu bewirken. Mit dem erfindungsgemäßen Artillerieprojektil wird zusätzlich zur Reduktion der Längsablage auch eine Reduktion der Querablage des Artillerieprojektiles im Zielgebiet und somit auf relativ einfache Weise eine wesentliche Verbesserung der Zielgenauigkeit realisiert. Vorteilhaft ist es hierbei, wenn die Impulselemente am Umfang des Artillerieprojektiles gleichmäßig verteilt angeordnet sind, weil dann die Ansteuerung des jeweils passenden Impulselementes vergleichsweise einfach möglich ist.Characterized in that in the spin-stabilized artillery projectile invention distributed around the circumference a number of impulse elements are provided, it is possible by appropriate activation of at least one corresponding impulse element to effect a reduction of the cross-placement of the artillery projectile in the target area. With the artillery projectile according to the invention, in addition to the reduction of the longitudinal storage, a reduction of the cross-placement of the artillery projectile in the target area and thus in a relatively simple manner, a substantial improvement in the accuracy of the target is realized. It is advantageous in this case if the pulse elements are arranged distributed uniformly on the circumference of the artillery projectile, because then the control of each matching pulse element is comparatively easily possible.

Bei dem erfindungsgemäßen drallstabilisierten Artillerieprojektil können die Impulselemente in der Ogive des Artillerieprojektiles vorgesehen sein. Bei einer derartigen Ausbildung können die Impulselemente von den pyrotechnischen Kraftelementen gebildet sein, die einem vorderen Ringbereich einer die Bremseinrichtung bedeckenden Haube zugeordnet sind, und mittels welchem die Haube von der Ogive des Artillerieprojektiles absprengbar ist. Derartige Impulselemente in Gestalt pyrotechnischer Kraftelemente sind in der eingangs zitierten DE 101 43 312 C1 beschrieben.In the spin-stabilized artillery projectile according to the invention, the momentum elements can be provided in the ogive of the artillery projectile. With such a design, the pulse elements may be formed by the pyrotechnic force elements, which are associated with a front annular region of a hood covering the braking device, and by means of which the hood of the ogive of the artillery projectile can be abspengbar. Such impulse elements in the form of pyrotechnic force elements are quoted in the opening paragraph DE 101 43 312 C1 described.

Bei dem Artillerieprojektil nach Anspruch 1 sind die Impulselemente an einem Ringelement vorgesehen, das zwischen dem Projektilzünder und dem Projektilgehäuse angeordnet ist. Hierdurch kann das Artillerieprojektil quasi unverändert mit einem bekannten Projektilzünder kombiniert werden .In the artillery projectile according to claim 1, the pulse elements are provided on a ring element which is arranged between the projectile fuse and the projectile housing. As a result, the artillery projectile can be virtually unchanged combined with a known projectile fuze.

Insbesondere bei Artillerieprojektilen großer Reichweite kann es bevorzugt sein, wenn die Impulselemente im Heckteil, d.h. im Base Bleed, des Artillerieprojektiles vorgesehen sind.Especially with long range artillery projectiles, it may be preferred if the impulse elements in the tail section, i. in Base Bleed, the artillery projectile.

Zur Bestimmung der jeweiligen zeitlichen Drehwinkelposition des Artillerieprojektiles und somit der an seinem Umfang verteilt vorgesehenen Impulselemente dient eine Einrichtung, die mit den Impulselementen, zu deren gezielter Aktivierung, zusammenwirkt. Diese Einrichtung kann im Artillerieprojektil vorgesehen sein, so dass sich eine autarke Einrichtung und ein autarkes Artillerieprojektil ergibt. Eine andere Möglichkeit besteht darin, dass diese Einrichtung satellitengestützt gesteuert wird. Eine satellitengestützte Steuerung eines bahnkorrigierbaren drallstabilisierten Artillerieprojektiles der eingangs genannten Art, d.h. zur Reduktion der Längsablage des Artillerieprojektiles in einem Zielgebiet, ist in der EP 1 103 779 B1 beschrieben, deren Offenbarungsgehalt, was die gezielte Aktivierung der am Umfang des Artillerieprojektiles vorgesehenen Impulselemente zur Reduktion der Querablage des Artillerieprojektiles in einem Zielgebiet anbelangt, Teil der vorliegenden Erfindung ist.To determine the respective angular position of rotation of the artillery projectile and thus distributed on its circumference provided impulse elements is a device that interacts with the pulse elements to their specific activation. This device can be provided in the artillery projectile, so that there is a self-sufficient device and a self-sufficient artillery projectile. Another possibility is that this device is controlled by satellite. A satellite-based control of a web-corrected spin-stabilized artillery projectile of the type mentioned, ie for the reduction of the longitudinal storage of the artillery projectile in a target area, is in the EP 1 103 779 B1 described, their disclosure content, which concerns the targeted activation of the impulse elements provided at the periphery of the artillery projectile in order to reduce the cross-placement of the artillery projectile in a target area, forms part of the present invention.

Das erfindungsgemäße bahnkorrigierbare drallstabilisierte Artillerieprojektil weist den Vorteil auf, dass mit konstruktiv einfachen Mitteln zusätzlich zur Reduktion der Längsablage eine Reduktion der Querablage des Artillerieprojektiles in einem Zielgebiet verwirklicht wird. Dabei wird die Reduktion der Querablage, d.h. die gesteuerte Seitenkorrektur des Artillerieprojektiles, zeitlich vor der Aktivierung der Bremseinrichtung zur Reduktion der Längsablage des Artillerieprojektiles im Zielgebiet durchgeführt, weil die Seitenkorrektur zeitlich schneller erfolgt als die Bremseinrichtung zur Reduktion der Längsablage wirksam wird.The web-correctable spin-stabilized artillery projectile according to the invention has the advantage that, with structurally simple means, in addition to the reduction of the longitudinal deposit, a reduction of the transverse placement of the artillery projectile in a target area is realized. Thereby, the reduction of the cross-shelf, i. the controlled page correction of the artillery projectile, carried out before the activation of the braking device for reducing the longitudinal storage of the artillery projectile in the target area, because the page correction is faster in time as the braking device for reducing the longitudinal shelf is effective.

Während bei dem bekannten drallstabilisierten Artillerieprojektil mit einer Reduktion der Längsablage also eine 1D-Korrektur erfolgt, ergibt sich beim erfindungsgemäßen Artillerieprojektil eine 1,5D-Korrektur.While in the known spin-stabilized artillery projectile with a reduction of the longitudinal rest thus a 1D correction, resulting in the artillery projectile according to the invention, a 1.5D correction.

Weitere Einzelheiten, Merkmale und Vorteile ergeben sich aus der nachfolgenden Beschreibung zweier in der Zeichnung verdeutlichter Ausführungsbeispiele des erfindungsgemäßen drallstabilisierten Artillerieprojektiles und seiner Wirkungsweise.Further details, features and advantages will become apparent from the following description of two illustrated in the drawings embodiments of the invention spin-stabilized artillery projectile and its mode of action.

Figur 1 zeigt längsgeschnitten den Vorderabschnitt einer Ausbildung des drallstabilisierten Artillerieprojektiles 10 mit einem in seiner Ogive 12 vorgesehenen Projektilzünder 14 und einer in der Ogive 12 vorgesehenen Bremseinrichtung 16, die fliehkraftbedingt durch pyrotechnische Kraftelemente 18 anstellbar ist, die einem vorderen Ringbereich 20 einer Haube 22 zugeordnet sind. FIG. 1 shows longitudinally sectioned the front portion of a formation of the spin-stabilized artillery projectile 10 with a provided in its ogive 12 projectile detonator 14 and a provided in the ogive 12 braking device 16 which is centrifugally force adjustable by pyrotechnic force elements 18, which are associated with a front ring portion 20 of a hood 22.

Die pyrotechnischen Kraftelemente 18 bilden Impulselemente 24 des Artillerieprojektiles 10, die am Umfang des Artillerieprojektiles 10 gleichmäßig verteilt angeordnet sind.The pyrotechnic force elements 18 form impulse elements 24 of the artillery projectile 10, which are arranged distributed uniformly on the circumference of the artillery projectile.

Die Bremseinrichtung 16 dient zur Reduktion der Längsablage des Artillerieprojektiles 10 in einem Zielgebiet (siehe die Figuren 3 und 4). In Figur 4 ist das Zielgebiet 26 ellipsenförmig, d.h. mit einem elliptischen Rand 28, verdeutlicht. Die durch den elliptischen Rand 28 begrenzte Ablagefläche 30 weist eine Längsachse A0 und eine Querachse B0 auf. Durch die Bremseinrichtung 16 ergibt sich eine Reduktion der Längsablage, d.h. der Längsachse A0, zu einem Betrag Ar. Eine Reduktion der Querachse B0 wird durch die Bremseinrichtung 16 des Artillerieprojektiles 10 nicht bewirkt, d.h. durch die Bremseinrichtung 16 wird die Ablagefläche 30 zu einer Ablagefläche 32 verkleinert, die durch die Randlinie 34 begrenzt ist.The braking device 16 serves to reduce the longitudinal storage of the artillery projectile 10 in a target area (see the Figures 3 and 4 ). In FIG. 4 is the target area 26 elliptical, ie with an elliptical edge 28, illustrated. The limited by the elliptical edge 28 shelf 30 has a longitudinal axis A 0 and a transverse axis B 0 . By the braking device 16 results in a reduction of the longitudinal shelf, ie the longitudinal axis A 0 , to an amount A r . A reduction of the transverse axis B 0 is not effected by the braking device 16 of the artillery projectile 10, ie by the braking device 16, the storage surface 30 is reduced to a storage surface 32 which is bounded by the edge line 34.

Mit Hilfe der am Umfang des Artillerieprojektiles 10 verteilten Impulselemente 24 ergibt sich durch passende Aktivierung der entsprechenden Impulselemente 24 bei einem Artillerieprojektil 10 mit Bremseinrichtung 16 eine Reduktion der Querablage des Artillerieprojektiles 10, d.h. eine weitere Reduktion der Ablagefläche 32 zu einer Ablagefläche 36, die durch die Randlinie 38 begrenzt ist. Die Ablagefläche 36 ist in x-Richtung durch die Längsabmessung Ar und in y-Richtung durch die Querabmessung Br bestimmt, wobei es bevorzugt ist, wenn Ar und Br gleich groß sind, so dass sich eine kreisrunde Ablagefläche 36 ergibt.With the help of the distributed on the circumference of the artillery projectile 10 pulse elements 24 is obtained by appropriate activation of the corresponding pulse elements 24 in an artillery projectile 10 with braking device 16, a reduction of the cross-stock of the artillery projectile 10, ie a further reduction of the storage surface 32 to a storage area 36 through the Edge line 38 is limited. The support surface 36 is determined in the x-direction by the longitudinal dimension A r and in the y-direction by the transverse dimension B r , wherein it is preferred if A r and B r are the same size, so that a circular support surface 36 results.
