Description
Zündladung Die Erfindung bezieht sich auf eine Zündladung aus rauchschwachem Nitrocellulosepulver für die Anfeuerung von Treibladungen, und zwar insbesondere auf eine Zündladung für Zündschrauben, wie sie bei Patronen für automatische Waffen etwa der Kaliber 20 bis 40 mm üblich sind.Ignition charge The invention relates to an ignition charge made of low-smoke Nitrocellulose powder for firing propellant charges, in particular on an ignition charge for ignition screws, such as those used in cartridges for automatic weapons around 20 to 40 mm caliber are common.
Bei der Verwendung der bekannten Zünd- bzw. Anfeuerungsladungen kann man - und zwar infolge ungenügenden Zünddruckes und/oder nicht ausreichend heißer Flamme der Zündladung - beim Abschuß gewisser Treibladungen vielfach eine überraschend starke Rauchentwicklung beobachten, wobei meistens gleichzeitig auf der Verschlußseite der Waffe brennende Gase austreten, ein Vorgang, der sich in extremen Fällen zum sogenannten »Stehfeuer« auswirken kann. Letzteres kann für die Bedienungsmannschaft der betreffenden Waffe recht gefährlich werden, insbesondere dann, wenn die Waffen in geschlossenen Räumen, wie Kampfwagen, Bunkern od. dgl., eingebaut sind.When using the known ignition or ignition charges man - as a result of insufficient ignition pressure and / or not sufficiently hotter Flame of the ignition charge - often a surprise when certain propellant charges are fired Observe strong smoke development, mostly at the same time on the closure side Burning gases escape from the weapon, a process which in extreme cases can lead to so-called "standing fire" can affect. The latter can be done for the operating team the weapon in question can be quite dangerous, especially if the weapons Are installed in closed rooms, such as combat vehicles, bunkers or the like.
Dieses Verschluß- bzw. Stehfeuer ergibt sich z. B. bei Gasdruckladern in der Regel dann, wenn die Verbrennung der Pulvergase noch nicht abgeschlossen ist, wenn das voreilende Geschoß die Anzapfbohrung im Lauf passiert und damit diese Öffnung freigibt, an der bekanntlich der Gasdruck für die Entriegelung des Verschlusses entnommen wird. Ähnliche Vorgänge zeigen sich auch bei Rückstoßladern, und zwar insbesondere dann, wenn die Verbrennung der Pulvergase zu Beginn der Öffnungsbewegung des Verschlusses noch nicht beendet ist.This locking or standing fire results z. B. with gas pressure boosters usually when the combustion of the powder gases has not yet been completed is when the leading bullet passes the tapping hole in the barrel and thus this Releases opening at which, as is well known, the gas pressure for unlocking the lock is removed. Similar processes can also be seen in recoil guns, namely especially when the combustion of the powder gases at the beginning of the opening movement the closure has not yet ended.
Die Erfindung hat sich die Aufgabe gestellt, diese Mängel zu beseitigen und eine Zündladung aufzuzeigen, die die Voraussetzungen für einen- zeitgerechten Verbrennungsablauf schafft, d. h. die den Anbrand und damit auch den Verlauf des Abbrennens der Treibladung so zu beeinflussen vermag, daß ein bestimmter maximaler Druck erreicht wird und das Ende der Verbrennung zeitlich und/oder örtlich an einer ganz bestimmten Stelle der Gasdruckkurve liegt. Die Zündladung muß also mit anderen Worten so beschaffen bzw. so aufgebaut sein, daß sie sowohl einen ausreichend hohen Zünddruck als auch eine ausreichend heiße Zündflamme erzeugt.The invention has set itself the task of eliminating these shortcomings and to show an ignition charge that meets the requirements for a timely Creates combustion process, d. H. which the burn and thus also the course of the Burning of the propellant charge is able to influence so that a certain maximum Pressure is reached and the end of the combustion in terms of time and / or location at a very specific point of the gas pressure curve. The ignition charge must therefore with others Words so designed or constructed that they both have a sufficiently high Ignition pressure as well as a sufficiently hot pilot flame is generated.
Gemäß der Erfindung wird dieses Problem dadurch gelöst, daß die Zündladung aus einem Gemisch von porösem Nitrocellulosepulver (Druckgaszündung) mit Nitroglyzerinpulver (Sauerstoffträger = heiße Flamme) besteht, wobei das Mischungsverhältnis zwischen 2: 1 und 7,5: 1 liegt.According to the invention, this problem is solved in that the ignition charge from a mixture of porous nitrocellulose powder (pressurized gas ignition) with nitroglycerin powder (Oxygen carrier = hot flame) there is, the mixing ratio between 2: 1 and 7.5: 1.
Nitroglyzerinpulver, wie es gemäß der Erfindung als Zündladung vorgesehen wird, hat einen Nitroglyzeringehalt von etwa 44,5 % und einen Nitrocellulosegehalt von etwa 52,5 Der Wärmegehalt beträgt etwa 1250 kcal/kg. Das optimale Mengenverhältnis der Mischung muß von Fall zu Fall ermittelt werden, und zwar u. a. unter Berücksichtigung der chemischen Zusammensetzung und damit der pyrotechnischen Eigenschaften der als Treibladung benutzten Pulversorte und der Bauart der Waffe selbst, weil ja von dieser Bauart der Zeitpunkt der Verschlußentriegelung weitgehend abhängt.Nitroglycerin powder, as provided according to the invention as an ignition charge has a nitroglycerin content of about 44.5% and a nitrocellulose content of about 52.5 The heat content is about 1250 kcal / kg. The optimal proportion the mixture must be determined on a case-by-case basis, including: considering the chemical composition and thus the pyrotechnic properties of the als Propellant charge used the type of powder and the design of the weapon itself, because of this Type of the time of the lock release largely depends.
Die Beigabe des Anteils an Nitroglyzerinpulver kann auf verschiedene Art und Weise erfolgen, so kann man z. B. das Nitroglyzerinpulver mit dem Nitrocellulosepulver vermischen; man kann aber auch das Nitroglyzerinpulver in Gestalt einer Folie od. dgl. in die Zündschraube einfügen. Im letzteren Fall kann es vorteilhaft sein, diese Folie gleich auch als Abdeckfolie (Deckel) für die Zündschraube zu benutzen.The addition of the portion of nitroglycerin powder can be in different ways Way done, so you can z. B. the nitroglycerin powder with the nitrocellulose powder mix; but you can also od the nitroglycerin powder in the form of a film. Insert the like into the ignition screw. In the latter case, this can be beneficial The foil can also be used as a cover foil (cover) for the ignition screw.
An Stelle einer auf mechanischem Wege erzeugten Mischung von Nitrocellulosepulver und Nitroglyzerinpulver kann die Zündladung auch aus einem chemischen Verbundkörper aus diesen beiden Pulversorten bestehen.Instead of a mechanically produced mixture of nitrocellulose powder and nitroglycerin powder, the ignition charge can also consist of a chemical composite consist of these two types of powder.
