Abstract

The method of mounting a radar reflector on an artillery shell contemplates providing a body constituted by a functional element and a sleeve element formed rotationally-symmetrical about a lengthwise axis of said body with at least one explosive device arranged at least at the neighborhood of an outer surface of said sleeve element near to one end of said sleeve element and remote from the functional element. The body is mounted on the artillery shell and the explosive device is detonated in order to establish a form-locking connection of the sleeve element with the shell. The detonation of the explosive device severs the sleeve element at the region of said one end of said sleeve element in order to provide a substantially straight-lined closure of the sleeve element about the artillery shell in order to avoid undesirably altering ballistic characteristics of the artillery shell.

Description

Die Erfindung betrifft einen an einem Artilleriegeschoss axial anfügbaren Körper mit einem als Radarreflektor ausgebildeten Funktionsteil. Ein derartiger Körper ist beispielsweise aus dem DE-Gebrauchsmuster 7934250 bekannt: in diesem Dokument wird beschrieben, dass der Radarreflektor als zusätzliches Bauteil am Boden des Geschosses anfügbar und darauf mittels Schrauben befestigbar ist. Diese Befestigungsart ist zwar sicher und einfach, erfordert jedoch das Bohren von Löchern und Schneiden von Gewinden in den Boden der Geschosse und somit eine entsprechende Vorbereitung, welche in einer Werkstatt durchgeführt werden muss.The invention relates to a body axially attachable to an artillery shell with a functional part designed as a radar reflector. Such a body is known, for example, from DE utility model 7934250: this document describes that the radar reflector can be attached to the floor of the projectile as an additional component and can be fastened thereon by means of screws. Although this type of fastening is safe and simple, it requires drilling holes and cutting threads in the floor of the storeys and therefore appropriate preparation, which must be carried out in a workshop.

Es ist daher die Aufgabe der Erfindung, einen radarreflektierenden Körper der eingangs erwähnten Art derart auszubilden, dass er amunveränderten normalen Artilleriegeschoss anfügbar und befestigbar ist, wobei die innen-und aussenballistische Charakteristik des mit dem radarreflektierenden Körper ausgerüsteten Geschosses nur unwesentlich von der Charakteristik des normalen Geschosses abweichen darf und zudem das Ausrüsten mit wenigen, leichten Handgriffen und mit verhältnismässig billigen Mitteln durchgeführt werden soll.It is therefore the object of the invention to design a radar reflecting body of the type mentioned at the outset in such a way that it can be attached and fastened to the ammunition-modified normal artillery projectile, the interior and exterior ballistic characteristics of the projectile equipped with the radar reflecting body being only insignificant from the characteristics of the normal projectile may deviate and also the equipment should be carried out with a few easy steps and with relatively cheap means.

Die Aufgabe wird dadurch gelöst, dass am Funktionsteil eine um eine Längsachse drehsymmetrische, zum Aufstecken auf das Geschoss bestimmte Hülse angeordnet ist.The object is achieved in that a sleeve which is rotationally symmetrical about a longitudinal axis and is intended to be plugged onto the projectile is arranged on the functional part.

Im folgenden wird die Erfindung unter Bezugnahme auf die Zeichnung näher beschrieben.The invention is described in more detail below with reference to the drawing.

Es zeigen:

  • Fig. 1 eine Explosionszeichnung eines Geschosses mit je einem vorne und hinten am Geschoss anfügbaren radarreflektierenden Körper, und
  • Fig. 2 bis 6 je eine Schnittzeichnung einer Variante der Ausbildung der Hülse.
Show it:
  • Fig. 1 is an exploded view of a projectile, each with a radar reflecting body attachable to the front and rear of the projectile, and
  • Fig. 2 to 6 each a sectional drawing of a variant of the design of the sleeve.

In Fig. 1 ist ein Artilleriegeschoss üblicher Art mit 1 bezeichnet. Ein erster radarreflektierender Körper 2 weist einen Boden 3 auf, welcher, etwa wie im DE-Gebrauchsmuster 7934250 beschrieben, als Mehrfach-Tripelspiegelreflektor ausgebildet ist. Am Boden 3 ist eine Hülse 4 angeformt, die dazu bestimmt ist, auf den Zapfen (Heckteil) des Geschosses aufgesteckt zu werden. Ein zweiter radarreflektierender Körper 5 weist eine Hülse 6 auf, die dazu bestimmt ist, auf die Bogenspitze (Bugteil) des Geschosses aufgesteckt zu werden, während - auf der Zeichnung nicht sichtbar - der vordere Teil 7 des Körpers 5 als Radarreflektor, z.B. als Fresnel-Linse oder als Van-Atta-Reflektor ausgebildet ist. Die beiden Körper 2 und 5 sind je um eine Längsachse 8,8' drehsymmetrisch ausgebildet, wobei im aufgesteckten Zustand die Längsachse 8,3' mit der Längsachse des Geschosses zusammenfällt. Auch sind die beiden Körper 2 und 5 in Fig. 1 als um die Längsachse 8,8' rotationssymmetrische Körper dargestellt; im nachstehenden werden aber auch Varianten mit drehsymmetrischen, jedoch nicht rotationssymmetrischen Körpern beschrieben. Der als Mehrfach-Tripelspiegelreflektor ausgebildete Körper 2 besteht aus Metall, beispielsweise aus Messing oder aus der im DE-Gebrauchsmuster 7934250 erwähnten Aluminiumlegierung. Der als Fresnel-Linse oder als Van-Atta-Reflektor ausgebildete Körper 5 ist beispielsweise zweiteilig mit einer aus Messing oder Aluminiumlegierung bestehenden Hülse 6 und einem aus Kunststoff wie Epoxy- oder Polyurethanharz bestehenden vorderen Teil 7, der auf an sich bekannte Weise zur Bildung einer Fresnel-Linse oder eines Van-Atta-Reflektors mit einem metallischen Schichtmuster (z.B. aus Kupfer oder Aluminium) beschichtet ist.In Fig. 1, an artillery projectile of the usual type is designated by 1. A first radar reflecting body 2 has a base 3, which, as described in DE utility model 7934250, is designed as a multiple triple mirror reflector. At the bottom 3, a sleeve 4 is formed, which is intended to be plugged onto the pin (rear part) of the projectile. A second radar reflecting body 5 has a sleeve 6 which is intended to be plugged onto the bow tip (bow part) of the projectile, while - not visible in the drawing - the front part 7 of the body 5 as a radar reflector, for example as a Fresnel Lens or designed as a Van Atta reflector. The two bodies 2 and 5 are each designed to be rotationally symmetrical about a longitudinal axis 8, 8 ', the longitudinal axis 8, 3' coinciding with the longitudinal axis of the projectile when plugged in. The two bodies 2 and 5 are also shown in FIG. 1 as bodies which are rotationally symmetrical about the longitudinal axis 8, 8 '; Variants with rotationally symmetrical, but not rotationally symmetrical bodies are also described below. The body 2, which is designed as a multiple triple mirror reflector, consists of metal, for example of brass, or of the aluminum alloy mentioned in DE utility model 7934250. The body 5 designed as a Fresnel lens or as a Van Atta reflector is, for example, in two parts with a sleeve 6 made of brass or aluminum alloy and a plastic such as epoxy or polyurethane resin existing front part 7, which is coated in a manner known per se to form a Fresnel lens or a Van Atta reflector with a metallic layer pattern (for example made of copper or aluminum).

In Fig. 2 ist im Schnitt eine Variante eines auf einen Geschosszapfen aufzusteckenden radarreflektierenden Körpers dargestellt. Dieser Körper ist einstückig aus Metall ausgebildet, es lassen sich jedoch ein Bodenteil 21 und eine Hülse 22 unterscheiden. Der Bodenteil 21 bildet auch den radarreflektierenden Funktionsteil; er ist zu diesem Zweck als Mehrfach-Tripelspiegelreflektor der im DE-Gebrauchsmuster 7934250 beschriebenen Art ausgebildet, was in der Zeichnung durch die Schnittgrenzen 23 und 24 dargestellt wird. Der gesamte Körper ist um eine Achse 25 drehsymmetrisch ausgebildet, während die Hülse 22 um diese Achse 25 rotationssymmetrisch ausgebildet ist, und zwar derart, dass sie auf den Geschosszapfen genau passend aufsteckbar ist. Zur Befestigung des Körpers auf dem Geschosszapfen ist auf der Innenfläche 26 der Hülse 22 eine Haftschicht 27 vorgesehen, die in der Zeichnung dicker eingezeichnet wird, als sie in Wirklichkeit ist. Diese Haftschicht 27 besteht beispielsweise aus einer Kunststoffschicht aus Epoxy- oder Polyurethanharz, welcher zur Erhöhung der Haftreibung zwischen den Oberflächen der Innenseite der Hülse und der Aussenseite des Geschosses beziehungsweise des Geschosszapfens ein Schleifmittel, beispielsweise pulverförmiger Korund beigegeben wird.In Fig. 2 a variant of a radar reflecting body to be plugged onto a projectile is shown in section. This body is made in one piece from metal, but a base part 21 and a sleeve 22 can be distinguished. The bottom part 21 also forms the radar-reflecting functional part; for this purpose it is designed as a multiple triple mirror reflector of the type described in DE Utility Model 7934250, which is shown in the drawing by the cutting boundaries 23 and 24. The entire body is designed to be rotationally symmetrical about an axis 25, while the sleeve 22 is designed to be rotationally symmetrical about this axis 25, specifically in such a way that it can be fitted onto the projectile pin in a precisely fitting manner. To attach the body to the projectile pin, an adhesive layer 27 is provided on the inner surface 26 of the sleeve 22, which is shown thicker in the drawing than it actually is. This adhesive layer 27 consists, for example, of a plastic layer made of epoxy or polyurethane resin, to which an abrasive, for example powdered corundum, is added in order to increase the static friction between the surfaces of the inside of the sleeve and the outside of the projectile or the projectile pin.

In einer weiteren, in Fig. 3 dargestellten Variante wird gezeigt, dass die Hülse 22 auf ihrer Innenfläche 26 mit Sicken 31 oder Klauen 32 versehen ist, welche die Hülse auf dem Geschosszapfen befestigen, sobald die Hülse auf den Zapfen aufgepresst wird. Sowohl die Sicken 31 als auch die Klauen 32 können um die Achse 25 rotationssymmetrisch auf der ganzen Innenfläche 26 verlaufen, sie können jedoch auch bloss als drehsymmetrisch auf der Innenfläche 26 angeordnete einzelne Ansätze ausgebildet sein, beispielsweise in der Gestalt von 6 je um 60° um die Achse 25 versetzten, auf dem Kreisumfang gemessen je ca. 50 langen Klauen, wie in Fig. 4 im Schnitt der Hülse 22 in Höhe der Klauen 32 dargestellt wird.In a further variant, shown in FIG. 3, it is shown that the sleeve 22 is provided on its inner surface 26 with beads 31 or claws 32 which fasten the sleeve on the projectile stud as soon as the sleeve is pressed onto the stud. Both the beads 31 and the claws 32 can also run rotationally symmetrically about the axis 25 on the entire inner surface 26, but they can also be formed merely as individual lugs arranged in a rotationally symmetrical manner on the inner surface 26, for example in the form of 6 each offset by 60 ° about the axis 25, measured on the circumference in each case about 5 0 long claws, as shown in Fig. 4 in section of the sleeve 22 at the level of the claws 32.

In einer weiteren, in Fig. 5 dargestellten Variante wird im Schnitt ein auf die Bogenspitze eines Geschosses aufzusteckender radarreflektierender Körper dargestellt. Der gesamte Körper ist um die Achse 51 rotationssymmetrisch ausgebildet. Die Hülse 52 aus Metall ist mit einem aus Kunststoff bestehenden radarreflektierenden Funktionsteil 53 verklebt. An der Aussenfläche 54 des Funktionsteiles 53 sind elektrisch leitende Streifen 55 angebracht, die zusammenwirkend eine Fresnel-Linse bilden. Der Innenteil 56 der Hülse ist derart geformt, dass er auf die Bogenspitze des Geschosses genau passt. Der Innenteil 57 des Funktionsteiles 53 wird zur Aufnahme des Kopfzünders des Geschosses mit einer entsprechenden Ausnehmung versehen. An der Aussenseite 58 der Hülse 52 ist in einem um die Achse 51 im wesentlichen rotationssymmetrisch angeordneten Wulst eine Sprengschnur vorgesehen, deren Zündung nach dem Aufstecken der Hülse auf das Geschoss auf an sich bekannte Weise durch Aufpressen und gegebenenfalls durch Sprengschweissen oder Elektroentladungsschweissung eine formschlüssige Verbindung der Hülse 52 mit der Bogenspitze des Geschosses bewirkt. Auch die in Fig. 3 und 4 gezeigten Sicken 31 und Klauen 32 können so ausgebildet sein, dass sie durch Elektroentladungsschweissung mit dem Geschosszapfen verschweissbar sind.In a further variant shown in FIG. 5, a radar reflecting body to be plugged onto the arch tip of a projectile is shown in section. The entire body is rotationally symmetrical about the axis 51. The sleeve 52 made of metal is glued to a radar-reflecting functional part 53 made of plastic. Electrically conductive strips 55 are attached to the outer surface 54 of the functional part 53, which cooperatively form a Fresnel lens. The inner part 56 of the sleeve is shaped in such a way that it fits exactly on the arch tip of the projectile. The inner part 57 of the functional part 53 is provided with a corresponding recess for receiving the top detonator of the projectile. On the outside 58 of the sleeve 52, a detonating cord is provided in a bead arranged essentially rotationally symmetrically about the axis 51, the ignition of which after the sleeve has been fitted onto the projectile in a manner known per se by pressing on and optionally by explosive welding or electric discharge welding, a positive connection of the Causes sleeve 52 with the arch tip of the projectile. The beads 31 and claws 32 shown in FIGS. 3 and 4 can also be designed such that they can be welded to the projectile stud by means of electrical discharge welding.

In Fig. 6 ist im Halbschnitt ein auf den Geschosszapfen aufzusteckender radarreflektierender Körper 63 sowie eine daran angeordnete Sprengvorrichtung 60 dargestellt. Mit Hilfe der Sprengvorrichtung 60 wird der Körper 63 nach dem als "Sprengschweissen" bekannten Verfahren am Geschoss befestigt. Der Körper 63 ist einstückig aus Metall, sein Bodenteil 64 ist als Mehrfach-Tripelspiegelreflektor ausgebildet, was in der Zeichnung durch die Schnittgrenzen 70 und 71 dargestellt wird. Eine Hülse 65 des radarreflektierenden Körpers 63 besitzt auf ihrer Aussenseite 73 eine ringförmige Nut 66.6 shows a half section of a radar reflecting body 63 to be plugged onto the projectile pin and an explosive device 60 arranged thereon. With the aid of the explosive device 60, the body 63 is attached to the projectile by the method known as "explosive welding". The body 63 is made in one piece from metal, its bottom part 64 is designed as a multiple triple mirror reflector, which is represented in the drawing by the cutting boundaries 70 and 71. A sleeve 65 of the radar reflecting body 63 has an annular groove 66 on its outer side 73.

Die Sprengvorrichtung 60 besteht aus einem zur Achse 61 rotationssymmetrischen Gehäuse 68, das mit Sprengstoff 67 gefüllt ist. Die Zündung des Sprengstoffs 67 erfolgt über mehrere Sprengschnüre 69, die in einem aus Hartschaumstoff ausgebildeten Körper 72 eingebettet sind. Durch die Sprengwirkung wird die Hülse 65 an der Stelle der Nut 66 durchtrennt, wodurch ein geradliniger Abschluss der Hülse 65 erreicht wird. Vor dem Sprengschweissen des radarreflektierenden Körpers 63 auf ein Geschoss wird dessen Heck mit Lösungsmittel gereinigt und entfettet und mit Schmirgeltuch abgerieben. Anschliessend wird der Körper 63 mit der Sprengvorrichtung 60 auf das Heck des Geschosses aufgesetzt und der Sprengstoff 67 - vorzugsweise aus einiger Distanz - gezündet.The explosive device 60 consists of a housing 68 which is rotationally symmetrical with respect to the axis 61 and which is filled with explosive 67. The explosive 67 is ignited by means of a plurality of detonating cords 69 which are embedded in a body 72 made of rigid foam. Due to the explosive action, the sleeve 65 is severed at the location of the groove 66, as a result of which the sleeve 65 is terminated in a straight line. Before the radar-reflecting body 63 is explosively welded onto a projectile, its rear is cleaned and degreased with solvent and rubbed off with an emery cloth. The body 63 is then placed with the explosive device 60 on the rear of the projectile and the explosive 67 is ignited, preferably from a distance.
