Description

B e s c h r e i b u n gDescription
Bei 1 adung .At 1 charge.
Die Erfindung betrifft eine Beiladung aus porösem Ex¬ plosivstoff zum Zünden einer Treibladung. Eine solche Beiladung stellt den Vermittler zwischen der eigent¬ lichen Zündladung und der anzuzündenden Treibladung dar. Sie soll sicherstellen, daß sich die von der Zünd¬ ladung ausgehende Zündung rasch auf die gesamte Treib¬ ladung ausbreitet. Daher muß die Beiladung eine hohe Abbrandgeschwindigkeit haben.The invention relates to an additional charge made of porous explosive for igniting a propellant charge. Such an additional charge represents the mediator between the actual priming charge and the propellant charge to be ignited. It is intended to ensure that the ignition originating from the priming charge quickly spreads to the entire propellant charge. The additional load must therefore have a high burn rate.
Bekannte Beiladungen bestehen aus porösen Pulvern, die eine große innere Oberfläche aufweisen und daher hohe Abbrandgeschwindigkei ten zeigen. Die Porosität wird normalerweise durch Einarbeiten leicht wasser¬ löslicher, fein gemahlener Salze in die Pulver und anschließendes Wiederauslaugen mit Wasser erzeugt. Das poröse Pulver liegt dann in einer granulierten Form vor; es muß zur Herstellung der fertigen Beila¬ dung in einem zusätzlichen Arbeitsgang noch konfek¬ tioniert werden, z.B. durch Einnähen in einen Stoff¬ beutel. Schon die Herstellung, insbesondere aber die Konfektionierung sind zeit- und arbeitsaufwendig. Au¬ ßerdem müssen diese pul vergefüll ten Stoffbeutel, da sie nicht formstabil sind, durch besondere Vorkehrungen exakt an der Treibladung fixiert werden. Der Erfindung liegt die Aufgabe zugrunde, eine Beila¬ dung für Treibladungen zu schaffen, die einfacher als bekannte Beiladungen herzustellen und im Einsatz leic ter zu handhaben ist.Known additional loads consist of porous powders, which have a large inner surface and therefore show high erosion speeds. The porosity is normally produced by incorporating easily water-soluble, finely ground salts into the powder and then leaching again with water. The porous powder is then in a granular form; it has to be made up in an additional operation in order to produce the finished image, for example by sewing it into a fabric bag. The manufacture, but especially the assembly, is time-consuming and labor-intensive. In addition, since they are not dimensionally stable, these powder-filled cloth bags must be precisely fixed to the propellant charge by special measures. The invention has for its object to provide a charge for propellant charges that is easier to produce than known additional charges and that is easy to use when used.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Beiladung ein kompakter Formkörper aus einer Masse ist, die als wesentlichen Bestandteil Nitrozellulose in Faserform enthält.This object is achieved in that the additional charge is a compact molded body made of a mass which contains nitrocellulose in fiber form as an essential component.

The required high burning rate is achieved in that the molded body consists of fibrous nitrocellulose. The fibrous nature of the nitrocellulose results in the high inner surface, which is a prerequisite for the high burning rate. At the same time

Z.B. wird in einem geeigneten Medium, insbesondere Wasser, aufgeschlämmte, fasrige Nitrozellulose durch Filtra¬ tion in den Formkörper überführt, dieser dann auf den25 can be carried out in a single easy and, if necessary, automated operation. For example, is suspended in a suitable medium, in particular water, fibrous nitrocellulose by filtration into the shaped body, which is then placed on the

Neben den fertigungstechnischen Vorteilen zeichnet sich die erfindungsgemäße Beiladung durch große Modi- 35 fikationsmögl ichkeit im Abbraπdverhalten , eine hohe mechanische Festigkeit und eine weite Var ationsbreite in der Formgebung aus. Im einfachsten Fall , wenn es zum Beispiel nur darum geht, die bisherigen Beiladungen zu ersetzen, wird man die erfindungsgemäße Beiladung in Tabletten-Form, z.B. als Zylinder mit Abmessungen in der Größenordnung von wenigen Zentimetern herstellen. Die zahlreichen Möglichkeiten der Formgebung können aber auch, was mit bisherigen Beiladungen praktisch nicht möglich war, in der Weise benutzt werden, daß Beiladung und Treibladung in ihrer Formgebung zur Erzie¬ lung einer optimalen Zündung genau aufeinander abge¬ stimmt werden. So kann eine Treibladung z.B. mit einem Beiladungs-Kern versehen werden, der durch die ganze Treibladung hindurchreicht. Wird die Treibladung aus mehreren Teilladungen zusammengesetzt, kann jede Teilla¬ dung einen Beiladungs-Kern erhalten, der an zwei gegen¬ überliegenden Stirnseiten die Teilladung freiliegt und sich in der zusammengesetzten Treibladung mit den übri¬ gen Treibladungs-Kernen zu einem durch die ganze Treib¬ ladung hindurchgehenden Kern-Strang zusammenfügt. Der durchgehende Kern-Strang gewährleistet eine rasche, gleichmäßige Ausbreitung der Zündung über alle Tei lla¬ dungen hinweg .In addition to the advantages in terms of production technology, the additional loading according to the invention is characterized by great modification possibilities in the imaging behavior, high mechanical strength and a wide range of variations in shape. In the simplest case, if, for example, it is only a matter of replacing the previous additional loads, the additional load according to the invention will be produced in tablet form, for example as a cylinder with dimensions of the order of a few centimeters. The numerous design options can also be used, which was practically not possible with previous additional loads, in such a way that the additional charge and propellant charge are precisely matched to one another in order to achieve optimum ignition. For example, a propellant charge can be provided with an additional charge core that extends through the entire propellant charge. If the propellant charge is composed of several partial charges, each partial charge can be given an additional charge core which exposes the partial charge on two opposite ends and which in the combined propellant charge with the remaining propellant charge cores forms one through the whole propellant charge core strand passing through the charge. The continuous core strand ensures rapid, uniform spreading of the ignition across all partial loads.
Das Abbrahdverhal ten der erfindungsgemäßen Beiladung kann vorteilhafterweise insbesondere dadurch modifi¬ ziert werden, daß die Formkörper-Masse außer Nitro¬ zellulose in Faserform fasrige Inertstoffe, wie z.B. Linters und/oder Zellstoff, enthält. Eine andere Mög¬ lichkeit besteht darin, statt natürlicher Nitrozellu¬ lose umgefällte Nitrozellulose zu verwenden, wodurch sich eine progressive Abbrandcharakteri sti k ergibt. Es hat sich als günstig herausgestellt, wenn die Nitro¬ zellulose in der Formkörper-Masse mit einem Anteil von mindestens 30 Gew.-%, vorzugsweise von mindestens 60 Gew.-% und ganz bevorzugt von ca. 80 Gew.-% vorliegt. Auch die Dichte des Formkörpers bzw. der Formkörper- Masse beeinflußt das Abbrandverhal ten und natürlich auch die mechanische Festigkeit. Mit höherer Dichte wird das Abbrandverhal ten für die Eignung als Beila- düng zunehmend unbrauchbarer, andererseits steigt die Festigkeit. Bis zu einer Dichte von 0,8 g/cm wird noch ein brauchbares Abbrandverhal ten erzielt. Beson-The imaging behavior of the additional charge according to the invention can advantageously be modified, in particular, in that the molding composition contains, in addition to nitrocellulose in fibrous form, fibrous inert substances, such as, for example, linters and / or cellulose. Another possibility is to use reprecipitated nitrocellulose instead of natural nitrocellulose, which results in a progressive combustion characteristic. It has turned out to be favorable if the nitro cellulose is present in the molding body in a proportion of at least 30% by weight, preferably at least 60% by weight and very preferably approximately 80% by weight. The density of the shaped body or the shaped body mass influences the Abbrandverhal th and of course the mechanical strength. With higher density, the burning behavior becomes more and more useless for the suitability as a supplement, on the other hand the strength increases. Up to a density of 0.8 g / cm, usable burn-off behavior is still achieved. Special
3 ders günstig ist eine Dichte von etwa 0,3 g/cm . Bei diesem Wert werden eine hohe Abbrandgeschwindigkeit 0 und gleichzeitig eine gute Festigkeit erhalten.3 ders favorable is a density of about 0.3 g / cm. With this value, a high burning rate 0 and at the same time good strength are obtained.
Zur Verbesserung ihres inneren Zusammenhal s kann die Formkörper-Masse mit einem Bindemittel versetzt sein. Geeignete Bindemittel sind Thermoplaste, z.B. das 5 gleichzeitig als Energieträger wirkende Polyvinylni- trat (PVN). Alternativ kommen Kunstharze infrage, die nach Erwärmen eine Klebebindung bewirken. Die Binde¬ mittel können bei der Herstellung bereits der Nitro¬ zellulose-Aufschl ämmung zugesetzt werden und/oder durch ° eine nachträgliche Tauchimprägnierung in die Formkör¬ per-Masse eingebracht werden.To improve their internal cohesion, the molding composition can be mixed with a binder. Suitable binders are thermoplastics, e.g. the 5 polyvinyl nitrate (PVN), which also acts as an energy source. Alternatively, synthetic resins can be used, which cause an adhesive binding after heating. The binders can already be added to the nitrocellulose slurry during manufacture and / or can be introduced into the molding composition by means of a subsequent dip impregnation.
Eine andere, aber auch zusätzlich anwendbare Möglich¬ keit der Verfestigung der Formkörper besteht darin, daß die Formkörper nach dem Trocknen an der Oberfl ¬ che mit einem geeigneten Lösemittel, z.B. mit Äthyl - acetat, angelöst werden. Hierdurch werden die Form¬ körper an der Oberfläche gelatiniert und erhalten so eine glatte, feste Außenhaut. Das Anlösen kann in der ° Weise geschehen, daß die Formkörper in das Lösemittel eingetaucht werden. Trotz der Tauchung tritt die Gelati¬ nierung überwiegend nur an der Oberfläche ein, da die anfänglich gelatinierte Oberfläche ein weiteres Eindrin¬ gen des Lösemittels verhindert. Schließlich können die Formkörper auch mit einer Lack¬ schicht, z.B. aus Polyurethanlack, überzogen werden.Another, but also additionally applicable, possibility of solidifying the shaped bodies is that after drying, the shaped bodies are dissolved on the surface with a suitable solvent, for example with ethyl acetate. As a result, the moldings are gelatinized on the surface and thus obtain a smooth, firm outer skin. The dissolving can be done in such a way that the shaped bodies are immersed in the solvent. Despite the immersion, gelation occurs predominantly only on the surface, since the initially gelatinized surface prevents further penetration of the solvent. Finally, the moldings can also be coated with a lacquer layer, for example made of polyurethane lacquer.
Die erfindungsgemäße Beiladung ist nicht nur zum Zünden von Treibladungen insbesondere großer Kaliber einsetz¬ bar, sondern kann auch selbst als Treibmittel anderer Munitionen, z.B. Schrotladungen, oder als Gasgenerator oder Ausstoßladung pyrotechni scher Erzeugnisse einge¬ setzt werden.The additional charge according to the invention can not only be used to ignite propellant charges, in particular of large caliber, but can also itself as propellant for other ammunition, e.g. Shot loads, or as a gas generator or discharge charge of pyrotechnic products.
Bei spiel :For example:
Eine erfindungsgemäße Beiladung besteht aus 5 g Nitro¬ zellulose mit einem Nitrierungsgrad von 13,4 %, aus 1 g Zellstoff und aus 0,05 g Stabilisator. Diese Stof¬ fe werden in Wasser aufgeschl mmt . Aus der Aufschläm- mung wird durch Absaugen ein zylindrischer Filterku¬ chen gebildet und dieser getrocknet. Hierdurch wird ein zylindrischer Formkörper erhalten, der einen Durch esser von etwa 2 cm und eine Höhe von etwa 3 cm hat. Der Formkörper wird in Äthylacetat getaucht, wodurch er an der Oberfläche gelatiniert wird. Der so erhal¬ tene Formkörper stellt die fertige Beiladung dar.An additional charge according to the invention consists of 5 g of nitrocellulose with a degree of nitration of 13.4%, of 1 g of pulp and of 0.05 g of stabilizer. These substances are slurried in water. A cylindrical filter cake is formed from the slurry by suction and dried. This gives a cylindrical shaped body which has a diameter of about 2 cm and a height of about 3 cm. The molded body is immersed in ethyl acetate, whereby it is gelatinized on the surface. The shaped body thus obtained represents the finished loading.
