Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Ausstoßen von Behältern, insbesondere von Munition, aus einem Gefechtskopf oder dergleichen Behältnis nach dem Oberbëgriff des Anspruchs 1.The invention relates to a device for ejecting containers, in particular ammunition, from a warhead or similar container according to the preamble of claim 1.

Derartige Vorrichtungen sind bekannt (vgl. DE-PS 30 26 159). Der Gasgenerator weist dabei eine massive Feststofftreibladung in dem gasdurchlässigen Rohr in der Mitte des Balges auf und ist damit hinsichtlich des Abgangsverhaltens der auszustoßenden Behälter praktisch nicht variabel.Such devices are known (see. DE-PS 30 26 159). The gas generator has a massive solid propellant charge in the gas-permeable tube in the middle of the bellows and is therefore practically not variable with regard to the outlet behavior of the containers to be ejected.

Der Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, liegt die Aufgabe zugrunde, das Abgangsverhalten der auszustoßenden Behälter in weiten Grenzen auf einfache Weise variierbar zu machen.The invention, as characterized in the claims, is based on the object of making the outlet behavior of the containers to be ejected easy to vary within wide limits.

Bei der erfindungsgemäßen Vorrichtung besteht der Gasgenerator also aus einem vorzugsweise mit einer Folie verdämmten z. B. als Siebrohr ausgebildeten gasdurchlässigen Rohr, in das eine teilchenförmige, vorzugsweise plättchenförmige Treibladung vorzugsweise aus einem doppelbasigen Treibstoff gefüllt ist Die Geometrie der Öffnungen des gasdurchlässigen Rohres ist auf die Treibladung abgestimmt, um die gewünschte Klemmung, d. h. das gewünschte Verhältnis der Gesamtflächen aller Öffnungen des gasdurchlässigen Rohres zu dessen Mantelfläche zu erhalten. Die Treibladung wird durch wenigstens eine pyrotechnische Anzündschnur entzündet, welche in der Mittelachse des gasdurchlässigen Rohres liegt und sich über die Gesamtlänge des Gasgeneratorrohres erstreckt und die ein Gemisch aus einer sauerstoffabgebenden Verbindung, wie Kalium- oder Ammoniumchlorat, sowie ein Metallpulver, wie Aluminiumpulver, gegebenen falls mit Zusätzen, wie einem Kunststoffbindemittel aufweist, also ein Gemisch, das ungefähr einem Verbundtreibsatz entspricht. Besonders bevorzugt sind sogenannte ITLX (Ignition Thin Layer X-Cord)-Anzündschnüre.In the device according to the invention, the gas generator thus consists of a z. B. designed as a sieve tube gas-permeable tube, in which a particulate, preferably platelet-shaped propellant charge is preferably filled from a double-base fuel to get gas-permeable pipe to the outer surface. The propellant charge is ignited by at least one pyrotechnic ignition cord, which lies in the central axis of the gas-permeable tube and extends over the entire length of the gas generator tube and which is a mixture of an oxygen-releasing compound, such as potassium or ammonium chlorate, and a metal powder, such as aluminum powder, if appropriate with additives such as a plastic binder has, that is a mixture that corresponds approximately to a composite propellant. So-called ITLX (Ignition Thin Layer X-Cord) ignition cords are particularly preferred.

Die Verwendung solcher Anzündschnüre führt zu einem einfachen Aufbau der Anzündkette bei hoher Zuverlässigkeit. Auch ist diese Anzündschnur mechanisch belastbar und führt zu einer geringen Streuung im Abgangsverhalten der Munitionsbehälter. Durch geeignete Abstimmung dieser Komponenten (Ausströmöffnungen des gasdurchlässigen Rohres, Verdämmung, Treibladungsgeometrie, pyrotech nische Anzündschnur) kann nicht nur die Anzündung und die Funktion des Gasgenerators gesteuert werden, sondern damit auch die Wirkung der Ausstoßvorrichtung in bezug auf das Abgangsverhalten der insbesondere Munition enthaltenden Behälter.The use of such ignition cords leads to a simple construction of the ignition chain with high reliability. This firing cord is also mechanically resilient and leads to little scatter in the outfeed behavior of the ammunition container. By suitable coordination of these components (outflow openings of the gas-permeable pipe, dam, propellant charge geometry, pyrotechnic igniter cord) not only the ignition and the function of the gas generator can be controlled, but also the effect of the ejection device in relation to the outlet behavior of the container, especially containing ammunition.

Gemäß Figur 1 befindet sich in der Hülle 2 eines Gefechts kopfes 1 Streumunition 3.According to Figure 1 is in the shell 2 of a war head 1 cluster munitions 3rd

Ferner ist ein Balg 4 vorgesehen, der konzentrisch zur Längsachse 5 des Gefechtskopfes 1 angeordnet ist. Der Balg 4 weist konkave, d. h. zur Längsachse 5 hin gerichtete Taschen 6 auf, in denen sich die Streumunition 3 befindet. Die beiden Stirnseiten des Balges 4 sind, was aus der Zeichnung nicht hervorgeht, durch Schottplatten abgedeckt. Bei Beaufschlagung des Balges 4 von innen mit Druckgas verformt er sich zu einem Zylinder, d. h. die Taschen 6 werden mit hoher Geschwindigkeit nach außen gestülpt und dabei die Streumunition 3 ausgestoßen. Sattvier können z. B. auch drei Taschen 6 vorgesehen sein.
Die Druckbeaufschlagung des Balges 4 erfolgt durch den Gasgenerator 7. Der Gasgenerator 7 besteht aus einem konzentrisch zur Längsachse 5 angeordneten Siebrohr 8, das an seiner Innenwand mit einer Polyethylenfolie 9 verdämmt ist. Entlang der gesamten Längsachse 5 erstrecken sich in der Mitte des Rohres 8 zwei Anzündschnüre 10, 10ʹ.Furthermore, a bellows 4 is provided, which is arranged concentrically to the longitudinal axis 5 of the warhead 1. The Bellows 4 has concave pockets 6, which are directed towards the longitudinal axis 5 and contain the cluster munitions 3. The two end faces of the bellows 4 are covered by bulkhead plates, which does not appear from the drawing. When the bellows 4 is pressurized from the inside, it deforms into a cylinder, ie the pockets 6 are turned outwards at high speed and the cluster munitions 3 are ejected in the process. Sattvier z. B. three pockets 6 may also be provided.
The bellows 4 is pressurized by the gas generator 7. The gas generator 7 consists of a sieve tube 8 which is arranged concentrically to the longitudinal axis 5 and is insulated on its inner wall with a polyethylene film 9. Two ignition cords 10, 10ʹ extend in the middle of the tube 8 along the entire longitudinal axis 5.

Die Anzündschnüre 10, 10ʹ werden durch ITLX-Anzündschnüre gebildet. Gemäß Figur 4 besteht eine solche Anzündschnur aus einem Schlauch 11 aus einer inneren Schlauchlage 30 aus Kunststoff, z. B. Polyethylen, einer Verstärkungslage 31 aus einem Fasergeflecht, z. B. Glasfasern, und einem Kunststoffaußenmantel 32, z. B. aus Polyethylen. In dem Schlauch 11 sind drei Stränge 33 angeordnet, welche aus einem Gemisch aus Kaliumperchlorat, Ammoniumperchlorat und Aluminiumpulver, gebunden mit Polyethlyenacrylat, gebildet sind.The igniter cords 10, 10ʹ are formed by ITLX igniter cords. According to Figure 4, such an ignition cord consists of a hose 11 made of an inner hose layer 30 made of plastic, for. B. polyethylene, a reinforcing layer 31 made of a fiber mesh, for. B. glass fibers, and a plastic outer jacket 32, z. B. made of polyethylene. In the tube 11 three strands 33 are arranged, which are formed from a mixture of potassium perchlorate, ammonium perchlorate and aluminum powder, bound with polyethylene acrylate.

Eine solche Anzündschnur weist eine hohe Fortpflanzungsgeschwindigkeit bei einer heißen, partikelreichen Flamme auf, wobei die sich inden Strängen 33 fortpflanzende Flammenfront zu einer Zerlegung des Schlauchs 11 führt.Such an ignition cord has a high propagation speed with a hot, particle-rich flame, the flame front propagating in the strands 33 leading to a disassembly of the hose 11.

Bei Verwendung mehrerer Anzündschnüre l0, 10ʹ, wie in Fig 3 gezeigt, werden diese durch Spannbänder 13ʹ zusammengehalten.When using several ignition cords l0, 10ʹ, as shown in Fig. 3, these are held together by straps 13ʹ.

Die aus Plättchen bestehende Treibladung 12 befindet sich in dem Raum zwischen den Anzündschnüren 10, 10ʹ und dem mit der Verdämmungsfolie 9 verdämmten Gasgenerator 8.The propellant charge 12 consisting of platelets is located in the space between the ignition cords 10, 10ʹ and the gas generator 8 which is insulated with the insulating foil 9.

Die Treibladung 12 besteht z. B. aus einem doppelbasigen Treibstoff.The propellant charge 12 consists, for. B. from a double-base fuel.

Gemäß Fig. 3 sind in die Anzündschnüre 10, 10ʹ pyrotechnische Verzögerungselemente 14 integriert, die von einer nicht dargestellten Verstärkerladung initiiert werden können.3 pyrotechnic delay elements 14 are integrated in the ignition cords 10, 10ʹ, which can be initiated by an amplifier charge, not shown.

Durch Verschlußteile 18, 18ʹ ist das Siebrohr 8 an beiden Enden verschlossen. Im Verschlußteil 18ʹ ist dabei das andere Ende der Anzündschnüre 10, 10ʹ mit z. B. Klebstoff 17 befestigt. Weiterhin sind auf dem Anzündschnüren 10, 10ʹ Inertkörper, z. B. in Form von Kunststoffschaumstoffringen 19, 19ʹ in beliebiger axialer Verteilung vorgesehen, z. B. zwischen der Treibladung 12 und dem Verzögerungselement 14 sowie am anderen Ende des Rohres 8.The sieve tube 8 is closed at both ends by closure parts 18, 18 versch. In the closure part 18ʹ the other end of the ignition cords 10, 10ʹ with z. B. adhesive 17 attached. Furthermore, 10 ʹ inert bodies, z. B. in the form of plastic foam rings 19, 19ʹ provided in any axial distribution, for. B. between the propellant charge 12 and the delay element 14 and at the other end of the tube 8th

Zum Ausstoß der Streumunition 3 wird zunächst die Gefechtskopfhülle 2 z. B. durch nicht dargestellte Schneidschnüre beseitigt. Daraufhin werden, verzögert durch das Verzögerungselement 14, die Anzündschnüre 10, 10ʹ gezündet. Die ITLX-Anzündschnüre 10, 10ʹ führen zur Bildung einer heißen partikelreichen Flamme. Die heißen Partikel werden zwischen die Plättchen der Treibladung 12 gedrückt, um diese zu entzünden. Auf diese Weise erfolgt die Anzündung der Treibladung 12 gleichzeitig über die gesamte Länge mit entsprechend raschem und kontrollierbarem Druckaufbau.To eject the cluster munitions 3, the warhead shell 2 is first z. B. eliminated by cutting cords, not shown. Thereupon, the ignition cords 10, 10 An are ignited, delayed by the delay element 14. The ITLX igniter cords 10, 10ʹ lead to the formation of a hot particle-rich flame. The hot particles are pressed between the platelets of the propellant charge 12 to ignite them. In this way, the propellant charge 12 is ignited simultaneously over the entire length with a correspondingly rapid and controllable pressure build-up.

Die Verdämmung bzw. die Folie 9 ist erforderlich, weil ein ausreichend hoher Druck bzw. eine ausreichend hohe Temperatur erforderlich sind, um die Treibladung 12 anzuzünden.The insulation or the film 9 is necessary because a sufficiently high pressure or a sufficiently high temperature are required to ignite the propellant charge 12.

Andererseits führt das Öffnen der Verdämmung 9 zu einem plötzlichen Druckabfall. Die heißen Partikel der ITLX-Anzündschnur 10, 10ʹ haben demgemäß nicht nur die Aufgabe, die Anzündung der Treibladung 12 zu bewirken, vielmehr verhindern sie auch, daß die Treibladung 12 in Folge des Druckabfalls nach dem Öffnen der Verdämmung 9 erlöschen kann.On the other hand, opening the dam 9 leads to a sudden drop in pressure. The hot particles of the ITLX ignition cord 10, 10ʹ accordingly not only have the task of causing the propellant charge 12 to be ignited, but also prevent the propellant charge 12 from extinguishing as a result of the pressure drop after the dam 9 is opened.

Durch den geschilderten Aufbau des Gasgenerators 7 kann also ein schneller und gleichmäßgier Druckaufbau in dem Balg 4 und damit eine hohe Abgangsbeschleunigung der Streumunition 3 erreicht werden.Due to the construction of the gas generator 7 described, a rapid and uniform build-up of pressure in the bellows 4 and thus a high acceleration of the discharge of the cluster munitions 3 can be achieved.

Ein wesentlicher Vorteil der erfindungsgemäßen Vorrichtung besteht nun darin, daß die Abgangsbeschleunigung oder allgemein das Abgangsverhalten der Streumunition den jeweiligen Anforderungen relativ leicht angepaßt und über die Länge des Balges variiert werden kann.An essential advantage of the device according to the invention is that the departure acceleration or generally the departure behavior of the cluster munitions can be adapted relatively easily to the respective requirements and can be varied over the length of the bellows.

Neben der Klemmung, d. h. dem Verhältnis der Gesamtfläche der Öffnungen des Siebrohres 8 zu dessen Mantelfäche, der Art der Verdämmung und der Art der Menge der Anzündschnüre 10, 10ʹ kann dies durch die Art und Menge des Treibstoffs sowie die Konfiguration der Treibladung 12 und deren axiale Verteilung erfolgen.In addition to clamping, i.e. H. the ratio of the total area of the openings of the sieve tube 8 to its jacket surface, the type of insulation and the type of quantity of the ignition cords 10, 10ʹ this can be done by the type and quantity of fuel and the configuration of the propellant charge 12 and its axial distribution.

Insbesondere ist es möglich, gemäß Fig. 2 die Treibladung 12 durch, in axialem Abstand voneinander angeordnete, sich radial erstreckende Trennwände 20 aus Intermaterial zwischen den Anzündschnüren 10, 10ʹ und dem Rohr 9 in einzelne Segmente oder Ringkammern 21 zu trennen. Die Trennwände 20 können dabei z. B. aus Kunststoff-Schaumstoffringen bestehen.In particular, it is possible, according to FIG. 2, to separate the propellant charge 12 into individual segments or annular chambers 21 by axially spaced apart, radially extending partition walls 20 made of inter material between the ignition cords 10, 10ʹ and the tube 9. The partitions 20 can, for. B. consist of plastic foam rings.

In jede dieser Kammern 21 kann nun gezielt eine bestimmte Treibstoffmenge eingebracht werden, z. B. um eine gleichmäßige Verteilung einer bestimmten Treibstoffmenge entlang dem Rohr 8 zu erhalten.In each of these chambers 21, a specific amount of fuel can now be introduced, z. B. to get a uniform distribution of a certain amount of fuel along the tube 8.

Auch können entlang dem Rohr 8 mehrere durch Schottplatten getrennte Bälge 4 hintereinander angeordnet sein, die jeweils mit Streumunition bestückt sind, wobei das Abgangsverhalten der Streumunition der einzelnen Bälge 4 in ähnlicher Weise, also z. B. durch die für jeden Balg 4 im Gasgenerator 7 vorgesehene Treibladungsmenge steuerbar ist, z. B. aber auch durch weitere in die Anzündschnüre 10, 10ʹ integrierte pyrotechnische Verzögerungselemente, wobei entweder die dadurch entstehenden gesamten Anzündeinheiten mit der entsprechenden Art, Menge und Verteilung der Treibladung 12 in einem einzigen Rohr 8 z. B. durch Trennwände oder Schottplatten voneinander getrennt oder mehrere getrennte komplette Gasgeneratoren 7 in der Gefechtskopflängsachse 5 in einer Reihe hintereinander angeordnet werden können.Also, several bellows 4 separated by bulkhead plates can be arranged one behind the other along the tube 8, each of which is equipped with cluster ammunition. B. is controllable by the amount of propellant charge provided for each bellows 4 in the gas generator 7, z. B. but also by further in the firing cords 10, 10schn integrated pyrotechnic delay elements, either the resulting entire firing units with the corresponding type, amount and distribution of the propellant charge 12 in a single tube 8 z. B. separated by partitions or bulkheads or several separate complete gas generators 7 can be arranged in a row in the warhead longitudinal axis 5 in a row.
