The bellows (4) is inflated by a gas generator (7) consisting of a gas-permeable tube (8) extending along the longitudinal axis (5). The propellant charge (12) of the gas generator (7) is designed to be particulate in order to achieve the greatest possible variation in the outlet behavior of the ammunition container (3), at least one ignition cord (10, 10 ') extending along the longitudinal axis of the tube (8), around which a particle ignition mixture (11) is arranged, so that the hot particles are pressed between the particles of the propellant charge (12) when the ignition mixture (11) burns off. A dam (9) is used to build up the initial pressure required for burning off the propellant charge (12).

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Ausstoßen von Behältern, insbesondere von Munition, aus einem Gefechtskopf oder dergleichen Behältnis nach dem Oberbegriff 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 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 die ein Gemisch aus einer sauer­stoffabgebenden Verbindung, wie Kalium- oder Ammonium­perchlorat, sowei ein Metallpulver, wie Aluminiumpul­ver gegebenenfalls mit Zusätzen, wie einem Kunststoff-­ Partikelanzündmischung vorgesehen. Durch geeignete Abstimmung dieser Komponenten (Ausströmöffnungen des gasdurchlässigen Rohres, Verdämmung, Treibladungsgeome­trie, pyrotechnische Anzündschnur und Partikel-Anzündmi­schung) kann nicht nur die Anzündung und Funktion des Gasgenerators gesteuert werden, sondern damit auch die Wirkung der Ausstoßvorrichtung in bezug auf das Abgangsverhalten der insbesondere Munition enthalten­den Behälter.In the device according to the invention, the gas generator thus consists of a preferably insulated with a film, for. B. formed as a sieve tube gas-permeable tube into which a particulate, preferably platelet-shaped propellant charge is filled. The geometry of the openings of the gas-permeable tube is matched to the propellant charge in order to obtain the desired clamping, ie the desired ratio of the total areas of all openings of the gas-permeable tube to its 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 which is a mixture of an oxygen-releasing compound, such as potassium or ammonium perchlorate, and a metal powder, such as aluminum powder, optionally with additives, such as a plastic Particle ignition mixture provided. Appropriate coordination of these components (outflow openings of the gas-permeable tube, dam, propellant charge geometry, pyrotechnic igniter cord and particle ignition mixture) not only controls the ignition and function of the gas generator, but also the effect of the ejection device in relation to the outflow behavior of the ammunition in particular Container.

Nachstehend ist die Erfindung anhand der Zeichnung näher erläutert. Darin zeigen

  • Figur 1 einen Gefechtskopf im Querschnitt;
  • Figur 2 eine teilweise längsgeschnittene Ansicht des Gasgenerators; und
  • Figur 3 einen der Figur 2 entsprechenden Längsschnitt, jedoch in vergrößerter und nur teilweiser Wieder­gabe;
The invention is explained in more detail below with reference to the drawing. Show in it
  • Figure 1 shows a warhead in cross section;
  • Figure 2 is a partially longitudinal sectional view of the gas generator; and
  • 3 shows a longitudinal section corresponding to FIG. 2, but in an enlarged and only partial reproduction;

Gemäß Figur 1 befindet sich in der Hülle 2 eines Gefechts­kopfes 1 Streumunition 3.According to FIG. 1, cluster munitions 3 are located in the shell 2 of a warhead 1.

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. Statt vier können z. B. auch drei Taschen 6 vorgesehen sein.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 in which the cluster munitions 3 are located. 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. Instead of four z. B. three pockets 6 may also be provided.

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.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, können z. B. durch eine sogenannte Hivelite-Schnur gebildet sein, welche durch ein Metallröhrchen gebildet wird, in dem eine Anzündmi­schung aus Cäsiumborhydrid, Kaliumnitrat als Oxidations­mittel und einem Polyethylenglykolbindemittel enthalten ist. Bei Verwendung mehrerer Anzündschnüre 10, 10ʹ wie in Fig. 3 gezeigt, werden diese durch Spannbänder 13ʹ zusammengehalten.The ignition cords 10, 10ʹ, z. B. be formed by a so-called hivelite cord, which is formed by a metal tube in which an ignition mixture of cesium borohydride, potassium nitrate as an oxidizing agent and a polyethylene glycol binder is contained. When using several ignition cords 10, 10ʹ as shown in Fig. 3, these are held together by straps 13ʹ.

Um die Anzündschnüre 10, 10ʹ ist eine Partikel-Anzündmi­schung 11 angeordnet, d. h. eine Anzündmischung, die beim Abbrand ein partikelreiches Heißgas erzeugt. Die Partikel-Anzündmischung 11 kann z. B. aus einem Gemisch aus einer Sauerstoff abgebenden Verbindung, wie Kaliumnitrat, und einem Metallpulver, z. B. Bor- oder Aluminiumpulver bestehen.A particle ignition mixture 11 is arranged around the ignition cords 10, 10ʹ. H. an ignition mixture that generates a particle-rich hot gas when it burns. The particle ignition mixture 11 can e.g. B. from a mixture of an oxygen-donating compound, such as potassium nitrate, and a metal powder, for. B. boron or aluminum powder.

Die Partikelanzündmischung 11 ist mit einer Schlauchfolie 13, vorzugsweise einem Schrumpfschlauch umgeben. In dem Ringraum zwischen der Partikel-Anzündmischung 11 bzw. der Schlauchfolie 13 und dem Rohr 8 bzw. der Verdämmungsfolie 9 befindet sich die aus Plättchen bestehende Treibladung 12. Die Schlauchfolie 13 verhin­dert, daß sich die Partikel-Anzündmischung 11 mit der Treibladung 12 im unbetätigbaren Zustand der Vorrich­tung vermischt und bewirkt eine gezielte, z. B. gleichmä­ßige Verteilung der Partikel-Anzündmischung 11 um die Anzündschnüre 10, 10ʹ.The particle ignition mixture 11 is surrounded by a tubular film 13, preferably a shrink tube. The propellant charge 12 consisting of platelets is located in the annular space between the particle ignition mixture 11 or the tubular film 13 and the tube 8 or the insulating film 9. The tubular film 13 prevents the particle ignition mixture 11 with the propellant charge 12 from being inoperable Condition of the device mixed and causes a targeted, z. B. uniform distribution of the particle ignition mixture 11 around the ignition cords 10, 10ʹ.

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. Die Verzögerungselemente 14 stecken in einem Gehäuse, das über eine Tülle 16 in ein Rohr 15 mündet. Es ist ersichtlich, daß die Anzündschnüre 10, 10ʹ, die Partikel-Anzündmischung 11 und die Schlauchfo­lie 13 eine Einheit bilden. Diese Einheit ist über den Folienschlauch 13 mit dem Rohr 15 verbunden.According to FIG. 3, pyrotechnic delay elements 14 are integrated in the ignition cords 10, 10ʹ, which can be initiated by an amplifier charge, not shown. The delay elements 14 are in a housing which opens into a pipe 15 via a spout 16. It can be seen that the ignition cords 10, 10ʹ, the particle ignition mixture 11 and the tubular film 13 form a unit. This unit is connected to the tube 15 via the film tube 13.

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 den 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 body 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 Anzündschnüre 10, 10ʹ führen zum Anbrennen der Partikel-Anzündmischung 11. Durch die brennende Partikel-Anzündmischung 11 wird die Schlauchfolie 13 zerstört, wodurch die heißen Partikel der Anzündmischung 11 zwischen die Plättchen der Treib­ladung 12 gedrückt werden und diese 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 ignition cords 10, 10ʹ lead to the burning of the particle ignition mixture 11. The tubular particle ignition mixture 11 is destroyed by the burning particle ignition mixture 11, whereby the hot particles of the ignition mixture 11 are pressed between the platelets of the propellant charge 12 and 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 gleichmäßiger 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 pressure build-up 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 Mantelfläche, der Art der Verdämmung und der Art und Menge der Anzündschnüre 10, 10ʹ kann dies durch die Art, Menge und axiale Verteilung 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 outer surface, the type of insulation and the type and amount of ignition cords 10, 10ʹ this can be done by the type, amount and axial distribution of the 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 Inertmaterial zwischen der Schlauchfolie 13 und dem Rohr 9 in einzelne Segmente oder Ringkammern 21 zu trennen. Die Trennwände 20 können dabei z. B. aus Kunststoff- oder 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 inert material between the tubular film 13 and the tube 9. The partitions 20 can, for. B. consist of plastic or 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 ignition cords 10, 10ʹ integrated pyrotechnic delay elements, either the resulting entire ignition 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.
