Abstract

The training cartridge for a mortar has a projectile casing, a ballistic cover covering the projectile casing, a propulsive charge case resting on the projectile casing, and a driver arranged in the bottom of the propulsive charge case. To make it possible to produce such known training cartridges in a simple and cost-effective way, the driver (13) and the propulsive charge case (14), the propulsive charge case (14) and the projectile casing (11), and the projectile casing (11) and the ballistic cover (12) are connected by means of a catch connection. <IMAGE>

Description

Die Neuerung betrifft eine Übungspatrone nach dem Oberbegriff des Anspruchs 1.The innovation relates to a practice cartridge according to the preamble of claim 1.

Ein Geschoß im Kaliber 40 mm für eine Granatpistole ist aus der DE-OS 31 49 430 bekannt. Bei diesem Geschoß besteht die Treibladungshülse aus dem relativ teuren Werkstoff Aluminium, der zunächst in aufwendigen Verarbeitungsschritten zur Treibladungshülse umgeformt wird, bis diese mit den übrigen Geschoßteilen verbunden werden kann.A projectile in 40 mm caliber for a grenade pistol is known from DE-OS 31 49 430. In this projectile, the propellant charge sleeve consists of the relatively expensive material aluminum, which is first formed into the propellant charge sleeve in complex processing steps until it can be connected to the other parts of the projectile.

In der Patentanmeldung P 35 07 643.7 wird bereits vorgeschlagen, die Treibladungshülse aus Gründen der Kosteneinsparung aus Kunststoff herzustellen, wobei die Treibladungshülse dann üblicherweise mit dem Geschoßkörper verklebt wird.Patent application P 35 07 643.7 already suggests producing the propellant charge sleeve from plastic for reasons of cost savings, the propellant charge sleeve then usually being glued to the projectile body.

Der Neuerung liegt die Aufgabe zugrunde, eine Übungspatrone für eine Granatpistole anzugeben, bei deren Herstellung weitere Kosteneinsparungen erzielt werden können.The innovation is based on the task of specifying a practice cartridge for a grenade pistol, the production of which can result in further cost savings.

Ausgehend von einer übungspatrone der eingangs näher bezeichneten Art wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst.Starting from an exercise cartridge of the type specified in the introduction, this object is achieved by the features specified in the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Neuerung gehen aus den Unteransprüchen hervor.Advantageous refinements and developments of the innovation emerge from the subclaims.

Die Neuerung wird nachfolgend unter Bezug auf die Zeichnung näher erläutert. Dabei zeigt die einzige Figur z. T. im geschnittenen Zustand eine Seitenansicht der Übungspatrone.The innovation is explained in more detail below with reference to the drawing. The only figure shows z. T. in the cut state a side view of the practice cartridge.

Die Übungspatrone 10 umfaßt eine Geschoßhülle 11, eine kopfseitig mit der Geschoßhülle 1 verbundene ballistische Haube 12, eine heckseitig an der Geschoßhülle 11 befestigte Treibladungshülse 12, sowie einen im Boden der Treibladungshüle 12 angeordneten Treiber 13, in dem die relativ geringe Treibladung angeordnet ist. Im Boden der Geschoßhülle 11 selbst ist noch ein in der Figur nicht sichtbar dargestellter Leuchtspursatz befestigt.The practice cartridge 10 comprises a projectile shell 11, a ballistic hood 12 connected to the head of the projectile shell 1, a propellant charge sleeve 12 attached to the rear of the projectile shell 11, and a driver 13 arranged in the bottom of the propellant charge shell 12, in which the relatively low propellant charge is arranged. In the floor of the projectile casing 11 itself, a tracer set, not shown in the figure, is attached.

Aus Gründen der Materialeinsparung bestehen Treibladungshülse 14 und ballistische Haube 12 aus Kunststoff und werden vorzugsweise im Spritzgußverfahren aus diesem hergestellt. Die ballistische Haube 12 besteht zweckmäßig aus Durethan, während die Treibladungshülse 14 aus Polyamid 6 oder 12 hergestellt ist.In order to save material, the propellant charge sleeve 14 and ballistic hood 12 are made of plastic and are preferably produced therefrom by injection molding. The ballistic hood 12 suitably consists of Durethan, while the propellant charge sleeve 14 is made of polyamide 6 or 12.

Gemäß der Neuerung ist der Treiber 13 mit der Treibladungshülse 14, diese ihrerseits mit der Geschoßhülle 11 und schließlich die ballistische Haube 12 ebenfalls mit der Geschoßhülle 11 durch eine Rastverbin- 'dung miteinander verbunden. Die erwähnten Teile lassen sich dadurch bei der Laborierung einfach zusammenstecken, wodurch sich eine preisgünstige Montage ergibt.According to the innovation, the driver 13 is connected to the propellant charge sleeve 14, which in turn is connected to the projectile casing 11 and finally the ballistic hood 12 is also connected to the projectile casing 11 by a snap connection. The parts mentioned can be easily plugged together in the laboratory, resulting in an inexpensive assembly.

Im folgenden werden die Rastverbindungen im einzelnen erläutert. Die Treibladungshülse 14 verfügt in ihrem Bodenbereich über einen im wesentlichen hohlzylindrischen Ansatz 14a, der in das Innere der Treibladungshülse 14 hineinragt und der über eine in Radialrichtung nach innen vorspringende umlaufende Kante 14b verfügt. Diese Kante 14b greift in eine Hinterschneidung mit konischer Randfläche in der Außenmantelfläche des Treibers 13 ein und sichert den Treiber 13 in dieser Einbaulage. Der Ansatz 14a steht im Bereich seiner Kante 14b unter in Radialrichtung nach innen gerichteter Vorspannung. Bei der Montage des Treibers 13 wird dieser von außen her in den Ansatz 14 eingeführt, wobei seine abgerundete Vorderkante 13a an der Kante 14b entlanggleitet und diese bis zum Einrasten aufweitet.The locking connections are explained in detail below. The propellant charge sleeve 14 has in its bottom region an essentially hollow cylindrical projection 14a which projects into the interior of the propellant charge sleeve 14 and which has a circumferential edge 14b projecting inwards in the radial direction. This edge 14b engages in an undercut with a conical edge surface in the outer lateral surface of the driver 13 and secures the driver 13 in this installed position. The extension 14a is in the region of its edge 14b under radial tension that is directed inwards. When the driver 13 is assembled, it is inserted into the extension 14 from the outside, its rounded front edge 13a sliding along the edge 14b and widening it until it engages.

Die Treibladungshülse 14 verfügt in ihrer der ballistischen Haube 12 zugewandten Stirnfläche ebenfalls über eine radial nach innen vorspringende Kante 14c, die nach Aufschieben auf die Außenmantelfläche lla der Geschoßhülle 11 ebenfalls in eine dort eingebrachte, ringförmig umlaufende Hinterschneidung einrastet und auf diese Weise Treibladungshüle 14 und Geschoßhülle 11 miteinander verbindet.The propellant charge sleeve 14 also has, in its end face facing the ballistic hood 12, a radially inwardly projecting edge 14c which, after being pushed onto the outer circumferential surface 11a of the projectile casing 11, also engages in an annular undercut introduced there, and in this way propellant charge casing 14 and projectile casing 11 connects with each other.

Schließlich verfügt auch die ballistische Haube 12 im Bereich ihrer der Treibladungshülse 14 zugewandten Stirnfläche über eine vorspringende Kante 12a, die ebenfalls in eine Hinterschneidung im Kopfbereich der Geschoßhülle 11 einrastet.Finally, the ballistic hood 12 also has a projecting edge 12a in the area of its end face facing the propellant charge sleeve 14, which also engages in an undercut in the head area of the projectile casing 11.

Da sehr strenge Anforderungen hinsichtlich der Lagerfähigkeit der Übungspatrone bestehen, werden auch die erwähnten Rastverbindungen zweckmäßig vor dem Zusammenfügen der jeweiligen Teile noch mit einem Kleber bzw. einem Dichtungslack bestrichen, um ein Eindringen von Feuchtigkeit in das Innere der Übungspatrone zu verhindern.Since there are very strict requirements regarding the shelf life of the practice cartridge, too the mentioned snap connections expediently coated with an adhesive or a sealing varnish before joining the respective parts in order to prevent moisture from penetrating into the interior of the training cartridge.
