VERBRENNBARE SCHUTZHÜLLE GEGEN THERMISCHE EINFLÜSSECOMBUSTIBLE PROTECTIVE COVER AGAINST THERMAL INFLUENCES
FÜR TREIBLADUNGEN OHNE METALLKARTUSCHEFOR DRIVING CHARGES WITHOUT A METAL CARTRIDGE
Der Wunsch, die üblichen Patronenhülsen aus Messing oder Stahl durch eine Hülse aus einem brennbaren Material zu ersetzen bzw. die Hülse vollkommen zu eliminieren, führte zur Entwicklung verbrennbarer Kartuschen bzw. zur hülsenlosen Munition.The desire to replace the usual cartridge cases made of brass or steel through a case made of a flammable Replacing material or completely eliminating the sleeve led to the development of combustibles Cartridges or for caseless ammunition.
Die verbrennbare Kartusche besteht aus einem hülsenförmigen Behälter, der .aus schnell verbrennenden Materialien wie Nitrozellulose, Polyvinylnitrat u.a. hergestellt ist und in dem die Hauptpulverladung sich als Schüttpulver befindet.The combustible cartridge consists of a sleeve-shaped Containers made of fast-burning materials such as nitrocellulose, polyvinyl nitrate, etc. is manufactured and in which the main powder charge is located as bulk powder.
Die hülsenlose Munition besteht in der Regel aus einem kompakten Körper, der aus gepressten und/oder verklebten Pulverelementen besteht.Caseless ammunition usually consists of one compact body, which consists of pressed and / or glued powder elements.

Bei Verwendung dieser beiden Arten von Treibladungen in grosskalibrigen Waffen mit geringer Schusskadenz bei denen an den Wandungen der Verbrennungskammer keine bleibenden extrem hohen Temperaturen auftreten genügt als Wärmeisolation im allgemeinen eine Lackschicht, die gleichzeitig die Aufgabe hat, die Pulverladung gegen Feuchtigkeit zu schützen.When using these two types of propellant charges in large-caliber weapons with low rate of fire which no permanent extremely high temperatures occur on the walls of the combustion chamber is sufficient as thermal insulation generally a layer of lacquer, which at the same time has the task of counteracting the powder charge To protect moisture.
Beim Verschuss der oben beschriebenen Munition in einer automatischen Waffe mit hoher Schusskadenz treten an den Wandungen der Verbrennungskammer Temperaturen von 3oo 0C und mehr auf. Um eine unkontrollierte Entzündung der Treibladung zu verhindern, muss die brennbare Hülse, bzw. der Pulverpressling mit einer Schutzhülle versehen werden, die diese so isoliert, dass z.B. bei Versagen des Anzünders genügend Zeit'vorhanden ist, um die Munition aus der Verbrennungskammer zu entfernen. Als grundsätzliche Bedingung für die Schutzhülle gilt, dass sie vollkommen und möglichst raucharm verbrennt.When Verschuss the ammunition described above, in an automatic weapon with a high rate of fire temperatures occur on the walls of the combustion chamber from 3oo 0 C and more. In order to prevent uncontrolled ignition of the propellant charge, the flammable case or powder compact must be provided with a protective cover that isolates it in such a way that, for example, if the igniter fails, there is enough time to remove the ammunition from the combustion chamber. The basic condition for the protective cover is that it burns completely and with as little smoke as possible.
Versuche mit ungeschützten Hülsen bzw. Treibstoffpresslingen haben gezeigt, dass bei Verwendung von Nitrozellulose -bzw. Nitrozellulose - Nitroglycerinmassen bei 215 °C die Zersetzung nach etwa 12o s einsetzt. Durch Erhöhung der Temperatur auf 25o 0C beginnt die Zersetzung nach etwa 2o s und bei 3oo C nach 2 s. Diese Zeit würde nicht ausreichen, die Waffe zu entladen. Lackschichten auf Kunststoffbasis, z.T. mit Mineralien, wie Asbest gefüllt, bringen nur unbedeutende Verbesserungen auf 5 - 6 s.Tests with unprotected sleeves or fuel pellets have shown that when using nitrocellulose -bzw. Nitrocellulose - Nitroglycerin masses at 215 ° C the decomposition begins after about 12o s. By increasing the temperature to 25o 0 C, the decomposition begins after about 20 s and at 300 C after 2 s. This time would not be sufficient to unload the weapon. Plastic-based paint layers, some of which are filled with minerals such as asbestos, bring only insignificant improvements to 5 - 6 s.

Durch die vorliegende Erfindung kann die Verweilzeit der Pulverladung bei 300 0C in der Verbrennungskammer um das 15-30-fache erhöht werden, und zwar durch Verwendung einer Isolationshülle aus Kunststoffschaum, der mit einem Sekundärsprengstoff gefüllt sein kann.With the present invention, the residence time of the powder charge at 300 ° C. in the combustion chamber can be increased by 15-30 times by using an insulating cover made of plastic foam, which can be filled with a secondary explosive.
Es wird daher erfindungsgemäß vorgeschlagen:It is therefore proposed according to the invention:
1. die verbrennbare Hülse üblicher Art (auf Nitrozellulosebasis u.a.) "bzw. die Presskörper der hülsenlosen Munition mit,einer Hülle von Polyurethanschaum von 0,3 - 20 mm Dicke zu versehen, wobei in der Schaummasse bis zu 80 % Sekundärsprengstoffe enthalten sind. Vorzugsweise werden mit Kohlensäure geschäumte Polyurethane verwendet und als Füllung vorzugsweise Sekundärsprengstoffe mit guter Säuerstoffbilanz und Schmelzpunkten von mehr als 200 0C. Zur Verbesserung der Sauerstoffbilanz können in begrenzten Mengen (zur Vermeidung von Rauchbildung) anorganische Sauerstoffträger lh die Schutzschicht eingearbeitet werden* Bei Verwendung von Kaliumnitrat wird gleichzeitig eine Mündungsfeuerdämpfung erzielt.1. To provide the combustible case of the usual type (based on nitrocellulose, etc.) "or the compacts of the caseless ammunition with a sheath of polyurethane foam 0.3-20 mm thick, the foam mass containing up to 80% secondary explosives. Preferably are used with carbon dioxide foamed polyurethanes, and preferably as a filling secondary explosives with good Säuerstoffbilanz and melting points of more than 200 0 C. in order to improve the oxygen balance may be used in limited amounts (to avoid formation of smoke) inorganic oxidizer lh the protective layer are incorporated * using potassium nitrate is at the same time achieved a muzzle flash attenuation.
Als SekundärSprengstoffe können Nitroguanidin, Ammoniumpikrat, Hexanitrooxanilid, Trinitrodiaminobenzol, Iktogen, Hexanitrostilben u. ä. verwendet werden.Nitroguanidine, ammonium picrate, Hexanitrooxanilide, trinitrodiaminobenzene, ictogen, hexanitrostilbene and the like can be used.
Die Schaumhülle kann in gleichmässiger Dicke von 0,3 - 1,0 mm mit einer Dichte von 0,4-1,2 g/cm' je nach Anteil an Füllmittel, aufgetragen werdenj sie kann aber auch mit 6-8 Rippen versehen werden wie aus der Figur zu ersehen ist.The foam cover can be evenly thick from 0.3 - 1.0 mm with a density of 0.4-1.2 g / cm 'depending on the proportion of filler, but it can also be provided with 6-8 ribs as can be seen in the figure.
609826/00 3 1609826/00 3 1
Die Rippen können eine Dicke bis zu 2,ο mm haben. Das Schäumen erfolgt in Formen, die entsprechend der gewünschten Oberflächenstruktur ausgearbeitet sind. Die Schaumschicht kann nachträglich auf die verbrennbare Hülse bzw. den Pulverpressling aufgebracht werden, sie kann aber auch vorher hergestellt werden und die Hülse oder der Pressling eingearbeitet werden.The ribs can be up to 2.0 mm thick. The foaming takes place in molds that are worked out according to the desired surface structure. The foam layer can subsequently be applied to the combustible sleeve or the powder compact but it can also be produced beforehand and the sleeve or pellet incorporated will.
