Description

Die Erfindung bezieht sich auf ein Sekundärgeschoß für einen Tandemgefechtskopf nach dem Oberbegriff des Anspruchs 1. Dieser Oberbegriff ist aus DE-A-3 941 445 bekannt.The invention relates to a secondary floor for a tandem warhead according to the preamble of claim 1. This preamble is known from DE-A-3 941 445.
Beim Häuserkampf oder gegen sonstige Deckungen feindlicher Kräfte besteht ein Bedarf an kostengünstigen Waffen und Munition. Durch die EP-A1- 0 583 642 ist ein Gefechtskopf mit einer Tandemladung bekannt. Der Gefechtskopf weist eine als Hohlladung ausgebildete Hauptladung und eine kaliberkleinere Nachschußladung auf. Beim Zielaufprall des Gefechtskopfes schlägt die Hohlladung einen Kanal durch das Ziel. Das als Splittergeschoß ausgebildete Sekundärgeschoß dringt durch diesen Kanal in das Ziel ein und detoniert hinter dem Ziel mit Splitterwirkung. Das Sekundärgeschoß wird allein aufgrund seiner Massenträgheit beim Aufschlag des Gefechtskopfes durch den Kanal bewegt. Eine separate Beschleunigungsladung für das Sekundärgeschoß ist nicht erforderlich. Die Splitterwirkung wird durch die Sprengladung und durch das Gehäuse des Sekundärgeschosses bewirkt. Aufgrund der Ausbildung des Sekundärgeschosses liegt die Splitterwirkung hauptsächlich in Schußrichtung, wobei unmittelbar im Nahbereich der Deckung eine nur geringe Splitterwirkung auftritt.In house warfare or against other coverings from hostile forces, there is a Need for inexpensive weapons and ammunition. Through EP-A1-0 583 642 a warhead with a tandem charge known. The warhead has one main charge designed as a hollow charge and a smaller-caliber additional charge on. When the warhead hits the target, the shaped charge strikes a channel through the goal. The secondary storey, designed as a fragmentary storey, penetrates through this channel into the target and detonates behind the target with a splintering effect. The secondary storey is only due to its inertia on impact of the warhead moved through the channel. A separate acceleration charge for the secondary floor is not necessary. The splintering effect is caused by the explosive charge and the housing of the secondary floor. The splintering effect is due to the design of the secondary floor mainly in the weft direction, with the immediate vicinity of the cover only a slight splintering effect occurs.
Zur Verbesserung der Splitterwirkung entgegen der Flugrichtung eines Geschosses ist es nach der DE-A1 39 41 445 vorgesehen, daß neben Splittern in einer Geschoßogive auch im Heck des Geschosses eine Sprengladung und ogivenförmig angeordnete Konstruktionsslpitter vorgesehen sind. Die Zündung der heckseitigen Sprengladung erfolgt von einem mittig gelagerten Zünder, wobei dieser Zünder die vordere Sprengladung von der hinteren Sprengladung trennt. Die vordere Sprengladung wird über einen, aus Sprengstoff bestehenden und an der vorderen Sprengladung anliegenden Zündverstärker gezündet, während die hintere Sprengladung einen Übertragungsdetonator und einen nachgeordneten Zündübertrager benötigt. Dieser Zündübertrager initiert die heckseitige Sprengladung exzentrisch, also am äußeren Rand der Sprengladung. Durch diese einseitige Zündung der etwa als Halbkugel ausgebildeten Sprengladung liegt eine sehr unterschiedliche Splitterdichte im Zielraum vor. Außerdem variiert die Energie der Konstruktionssplitter entsprechend.To improve the splinter effect against the direction of flight of a projectile it is provided according to DE-A1 39 41 445 that in addition to splinters in a floor arch an explosive charge and ogive-shaped also in the rear of the floor arranged construction slitter are provided. Ignition of the rear Explosive charge takes place from a centrally located detonator, this detonator being the separates the front explosive charge from the rear explosive charge. The front explosive charge is about an explosive consisting of and on the front explosive charge adjacent ignition amplifier ignited while the rear explosive charge a transmission detonator and a downstream ignition transformer are required. This ignition transmitter initiates the explosive charge on the rear eccentrically, i.e. on outer edge of the explosive charge. This one-sided ignition of the explosive charge designed as a hemisphere has a very different fragment density in the target area. In addition, the energy of the construction splinters varies corresponding.
Es ist die Aufgabe der Erfindung, eine Übertragung der Zündung von einem Zünder mit nur einem Zünderausgang auf die vordere und die hintere Wirkladung eines Sekundärgeschosses vorzuschlagen, die zu einer gesteigerten Splitterwirkung führt. Diese Übertragung der Zündung soll konstruktiv einfach und kostengünstig sein.It is the object of the invention to transfer the ignition from an igniter with only one detonator output on the front and the rear active charge one Propose secondary floor, which leads to an increased fragmentation effect leads. This transfer of the ignition is to be structurally simple and inexpensive be.

Die Überzündvorrichtung 25 weist ein Gehäuse 26 mit zwei Flanschen 22 und mit einem zünderseitigen, zentralen Zapfen 27 auf. In dem Gehäuse 26 sind Ausnehmungen 28 bis 31 mit einer Verstärkerladung 32 aus Sprengstoff.The igniter 25 has a housing 26 with two flanges 22 and a central pin 27 on the ignition side. Recesses are in the housing 26 28 to 31 with an amplifier charge 32 made of explosives.
Die Verstärkerladung 32 ist in Richtung auf die vordere Wirkladung 13 scheibenförmig ausgebildet und weist einen Durchmesser 33 auf, der nahezu dem Durchmesser 34 der vorderen Wirkladung 13 entspricht.The booster charge 32 is disk-shaped in the direction of the front active charge 13 formed and has a diameter 33 which is almost the diameter 34 corresponds to the front active charge 13.
Die hintere Wirkladung 14, siehe auch Fig. 5, nimmt den Zünder 20 in einer Bohrung 40 bis auf einen Ringabschnitt 41 auf In diesem Bereich liegt ein Gewindering 42 des Zünders 20, wobei dieser mit dem Gehäuse 26 über eine Gewindeverbindung 43 verschraubt ist. The rear active charge 14, see also FIG. 5, takes the igniter 20 in a bore 40 except for a ring section 41 In this area there is a threaded ring 42 of the igniter 20, this with the housing 26 via a threaded connection 43 is screwed.
Einstückig mit der hinteren Wirkladung 14 verbunden sind zwei zungenartige Sprengstoffpole 50. Nachdem der Zünder 12 komplett in einer zylindrischen Metallhülse 52 aus Aluminium angeordnet ist, wird der für die Sprengstoffpole 50 benötigte Raum durch entsprechende Ausnehmungen 55 am Gehäuseteil 11 geschaffen. Die Metallhülse 52 kapselt die hintere Wirkladung 14 vollständig ab. Ein eleastisches Element zwischen den Gehäuseteilen 10 ist mit 110 bezeichnet. Einer der Flansche 22 ist bei 111 verstiftet.Two tongue-like are integrally connected to the rear active charge 14 Explosive poles 50. After the detonator 12 completely in a cylindrical metal sleeve 52 made of aluminum, that for the explosive poles 50th required space created by corresponding recesses 55 on the housing part 11. The metal sleeve 52 completely encapsulates the rear active charge 14. A Elastic element between the housing parts 10 is designated 110. One the flanges 22 are pinned at 111.
Im Überzündbereich 60 sind am Gehäuse 26 zwei dünnwandige Wandabschnitte 59 vorgesehen, so daß die Überzündung von der Verstärkerladung 32 zu den Sprengstoffpolen 50 - also auf zwei Wegen - erfolgen kann.In the ignition area 60 there are two thin-walled wall sections 59 on the housing 26 provided so that the ignition from the booster charge 32 to the explosive poles 50 - that is, in two ways.
Die Querschnitte der Sprengstoffpole 50 sind so bemessen, daß die Durchzündung zum Sprengstoffblock 19 der hinteren Wirkladung 14 gewährleistet ist.The cross sections of the explosive poles 50 are dimensioned such that the ignition to the explosives block 19 of the rear active charge 14 is guaranteed.
Bei Aufschlag des Tandemgefechtskopfes 4 auf eine nicht dargestellte Deckung wird durch die ebenfalls nicht dargestellte Hohlladung ein Durchschußkanal in der Deckung erzeugt. Durch diesen Durchschußkanal dringt das vom Gehäuse 3 abgelöste Sekundärgeschoß. Aufgrund einer entsprechend eingestellten Zeitverzögerung zündet der Detonator 21 des Zünders 20 die Verstärkerladung 32. Ausgehend von der Verstärkerladung 32 wird die vordere Wirkladung 13 und gleichzeitig werden die Sprengstoffpole 50 gezündet, in dem in den Überzündbereichen 60 das Gehäuse 26 durchschlagen wird. Die einander gegenüberliegenden Sprengstoffpole 50 leiten dem Sprengimpuls symmetrisch über einen Halsbereich 61 zum Sprengstoffblock 19. Die gleichzeitige Detonation der vorderen und der hinteren Wirkladung 13, 14 führt sowohl zu einer vorderen Splitterverteilung als auch zu einer hinteren Splitterverteilung. Die Splitterverteilung aufgrund der hinteren Wirkladung 14 ist gerade in Richtung auf den Durchschußkanal und dessen Umgebungsfeld groß.When the tandem warhead 4 strikes a cover, not shown is a bullet channel in the Cover generated. The detached from the housing 3 penetrates through this penetration channel Secondary floor. Due to a time delay set accordingly detonator 21 of igniter 20 ignites amplifier charge 32. Starting from the booster charge 32 becomes the front active charge 13 and simultaneously the explosive poles 50 are detonated, in which in the ignition areas 60 Housing 26 is penetrated. The opposite poles of explosives 50 conduct the explosive pulse symmetrically over a neck area 61 to the explosive block 19. The simultaneous detonation of the front and rear active charges 13, 14 leads to both a front splinter distribution and one rear splinter distribution. The splinter distribution due to the rear active charge 14 is straight in the direction of the bullet channel and its surrounding field large.
