Description
Die Erfindung betrifft eine Patrone mit elektrothermischer Anzündvorrichtung.The invention relates to a cartridge with electrothermal ignition device.
Mit hochenergetischen Treibladungspulvern, insbesondere mit NENA-Treibladungspulver (NENA = N-(2-nitroxy)-nitraminethan) oder DNDA-Treibladungspulver (DNDA = Dinitro-Diaza-Alkane), lassen sich wesentlich höhere Beschleunigungsleistungen von aus Rohrwaffen verschießbaren Geschossen erzielen als mit herkömmlichen Treibladungspulvern. Dabei ist in der Regel die Schußgastemperatur derartiger Treibladungspulver und damit auch die Rohrerosion geringer als bei bekannten Pulvern. Die hohe Aktivierungsenergie der hochenergetischen Treibladungspulver erschwert allerdings die Anzündung mit Hilfe von pyrotechnischen Anzündladungen. Die verminderte Anzündwilligkeit des Treibladungspulvers führt außerdem zu einer Erhöhung der Anzündverzugszeiten und zu einer erhöhten Streuung der Anzündzeiten.With high-energy propellant charge powders, in particular with NENA propellant charge powder (NENA = N- (2-nitroxy) -nitraminethan) or DNDA propellant charge powder (DNDA = dinitro-diaza-alkane), significantly higher rates of acceleration can be achieved by shootable bullets than with conventional ones propellant powders. In this case, the shot gas temperature of such propellant charge powder and thus also the pipe erosion is generally lower than in known powders. However, the high activation energy of the high-energy propellant charge powder complicates the ignition by means of pyrotechnic ignition charges. The reduced ignitability of the propellant charge powder also leads to an increase of the ignition delay times and to an increased spread of the ignition times.
Um eine sichere und schnelle Anzündung einer Patrone, z.B. mit NENA-Treibladungspulver, zu gewährleisten, hat es sich als vorteilhaft erwiesen, statt einer pyrotechnischen Anzündladung eine elektrothermische Anzündvorrichtung zu verwenden. Dabei wird zur Zündung des Treibladungspulvers im bodenseitigen Bereich der entsprechenden Patrone ein drahtförmiger Leiter von einem derart hohen Strom durchflossen, daß er explosionsartig verdampft und einen energiereichen Lichtbogen erzeugt. Der Lichtbogen zündet dann das entsprechende Treibladungspulver an.To ensure a safe and quick ignition of a cartridge, e.g. With NENA propellant charge powder, it has proven to be advantageous to use an electrothermal ignition device instead of a pyrotechnic ignition charge. In this case, a wire-shaped conductor is traversed by such a high current that it evaporates explosively and generates a high-energy arc to ignite the propellant charge powder in the bottom region of the corresponding cartridge. The arc then ignites the corresponding propellant charge powder.
Wie Versuche der Anmelderin außerdem gezeigt haben, kann mit einer derartigen elektrothermischen Anzündvorrichtung auch die relativ große Temperaturabhängigkeit von NENA-Treibladungspulver, die zu einer entsprechenden Abhängigkeit der Beschleunigungsleistung führt, über die Menge der dem Plasmaanzündsystem zugeführten elektrischen Energie kompensiert werden.As experiments by the Applicant have also shown, with such an electrothermal ignition device, the relatively large temperature dependence of NENA propellant charge powder, which leads to a corresponding dependence of the acceleration power, on the amount of the plasma ignition system supplied electrical Energy be compensated.
Als nachteilig hat sich bei dieser elektrothermischen Anzündvorrichtung allerdings erwiesen, daß durch die Erzeugung des bodenseitigen Lichtbogens zunächst nur ein relativ geringer Prozentsatz an Treibladungspulver gezündet wird und sich insbesondere bei schwer anzündbaren Treibladungspulvern häufig kein reproduzierbares Abbrennverhalten des Treibladungspulvers ergibt.A disadvantage has proved in this electrothermal ignition device, however, that initially only a relatively small percentage of propellant powder is ignited by the generation of the bottom-side arc and often results in reproducible burning behavior of the propellant powder, especially in hard-to-ignite propellant.
Um ein reproduzierbares Abbrennverhalten des Treibladungspulvers zu erhalten, wird in der nicht vorveröffentlichten deutschen Patentanmeldung DE 199 21 379.8 vorgeschlagen, die drahtförmigen Leiter nicht unmittelbar durch die Treibladung hindurchzuführen, sondern innerhalb von ebenfalls aus Treibladungspulver bestehenden Röhren anzuordnen. Diese Treibladungspulver-Röhren bilden dann innerhalb des Treibladungsaufbaus Anzündkanäle. Bei Aktivierung der Anzündvorrichtung verdampft zunächst der drahtförmige Leiter und im Inneren der jeweiligen Treibladungspulver-Röhren entsteht ein Lichtbogenplasmakanal. Über die Plasmakanäle wird die Energie über Strahlungstransportmechanismen an die Umgebung abgegeben. Diese Energieabgabe führt zu einer raschen Anzündung der Treibladungspulver-Röhren und zu deren Fragmentierung. Die brennenden Fragmente (hot spots) der Treibladungspulver-Röhren sowie die freigegebene Lichtbogenstrahlung verursachen ein schnelles und gleichmäßiges Anzünden des Treibladungsaufbaus.In order to obtain a reproducible burning behavior of the propellant charge powder, German Patent Application DE 199 21 379.8, not prepublished, proposes not passing the wire-shaped conductors directly through the propellant charge, but rather arranging them within tubes likewise made of propellant charge powder. These propellant powder tubes then form firing channels within the propellant charge structure. When the ignition device is activated, the wire-shaped conductor first evaporates, and an arc plasma channel is formed inside the respective propellant charge powder tubes. Via the plasma channels, the energy is released via radiation transport mechanisms to the environment. This release of energy leads to a rapid ignition of the propellant charge powder tubes and their fragmentation. The burning fragments (hot spots) of the propellant charge powder tubes as well as the released arc radiation cause a quick and uniform lighting of the propellant charge buildup.
Allerdings hat sich gezeigt, daß bei Verwendung von Treibladungspulver-Röhren aus grafitiertem Treibladungspulver, wie es üblicherweise im Handel erhältlich ist, ein relativ hoher Bedarf an elektrischer Energie erforderlich ist, um eine ausreichende Anzündwechselwirkung mit dem Treibladungspulver zu erzielen.However, it has been found that when using propellant powder tubes of graphitized propellant powder, as is commonly available on the market, a relatively high demand for electrical energy is required to achieve a sufficient ignition interaction with the propellant charge powder.
Aus der DE 198 34 058 A1 ist es bekannt, Pulverstangen und O-Lochpulverkörner als Hauptbestandteile mit einer höheren Transparenz auszustatten, wodurch die Abbrandgeschwindigkeit des Treibladungspulvers durch die elektrische Plasmastrahlung gezielt beeinflußt werden soll.It is known from DE 198 34 058 A1 to use powder rods and O-hole powder grains as Main components with a higher transparency equip, whereby the burning rate of the propellant charge powder is to be influenced by the electrical plasma radiation targeted.
Aus der WO 00/17598 A und aus der US-A-5 231 242 sind indirekt auf das Treibladungspulver einwirkende elektrothermische Anzündvorrichtungen bekannt, welche aufgrund ihrer Anordnungen in nicht brennbaren Röhren den Nachteil eines hohen Energiebedarfs haben.From WO 00/17598 A and US Pat. No. 5,231,242, electrothermal ignition devices acting indirectly on the propellant charge powder are known, which due to their arrangements in non-combustible tubes have the disadvantage of a high energy requirement.
Ausgehend von der nicht vorveröffentlichten DE 199 21 379.8 liegt der Erfindung die Aufgabe zugrunde, eine Patrone anzugeben, bei welcher auch schwer anzündbare Treibladungspulver, insbesondere NENA- oder DNDA-Treibladungspulver, schnell und sicher anzündbar sind, wobei der Bedarf an elektrischer Energie möglichst gering sein soll.Starting from the non-prepublished DE 199 21 379.8, the invention has for its object to provide a cartridge in which also difficult to ignite propellants, especially NENA or DNDA propellants, can be quickly and safely ignited, the need for electrical energy to be minimized should.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is solved by the features of claim 1. Further advantageous embodiments of the invention disclose the dependent claims.
Im wesentlichen liegt der Erfindung der Gedanke zugrunde, zur schnellen und sicheren Anzündung transparente Treibladungspulver-Röhren zu verwenden. Dabei hat sich als Treibladungspulver besonders das als JA2 bezeichnete Nitrocellulose-Pulver als geeignet erwiesen. Damit dieses Treibladungspulver transparent ist, darf es keine Rußanteile enthalten und die übliche Grafitierung der äußeren Oberfläche muß entfallen.Essentially, the invention is based on the idea to use transparent propellant charge powder tubes for fast and reliable ignition. In particular, the nitrocellulose powder designated as JA2 has proved to be suitable as a propellant charge powder. In order for this propellant powder is transparent, it must not contain soot particles and the usual graphitization of the outer surface must be eliminated.
Durch die Verwendung optisch transparenter Treibladungspulver-Röhren kann die von den Plasmakanälen emittierte Strahlung ohne große Absorptionsverluste zum Treibladungsaufbau der Patrone gelangen. Außerdem erzeugt die Plasmastrahlung eine Veränderung der abbrandwirksamen Oberfläche der transparenten Treibladungspulver-Röhren, die zu einer wesentlich beschleunigten Umsetzung der Röhren und damit zur Unterstützung des Anzündvorganges führt. Die Ausnutzung dieser Eigenschaften hat eine deutliche Verringerung des elektrischen Energiebedarfs des Plasmaanzündsystems zur Folge.By using optically transparent propellant powder tubes, the radiation emitted by the plasma channels can reach the propellant charge buildup of the cartridge without great absorption losses. In addition, the plasma radiation produces a change in the erosion-effective surface of the transparent propellant powder tubes, which is a significant accelerated implementation of the tubes and thus in support of the ignition process leads. The exploitation of these properties results in a significant reduction in the electrical energy requirement of the plasma ignition system.
Außerdem hat sich gezeigt, daß bei Verwendung optisch transparenter Treibladungspulver-Röhren der Bedarf an zusätzlicher elektrischer Energie für die Temperaturkompensation des NENA-Treibladungspulvers gegenüber dem Bedarf bei nicht transparenten Röhren verringert wird.In addition, it has been found that using optically transparent propellant powder tubes reduces the need for additional electrical energy for temperature compensation of the NENA propellant charge powder over the need for non-transparent tubes.
Bei Anwendung des DNDA-Treibladungspulvers kann diese zusätzliche elektrische Energie entfallen, da das DNDA-Treibladungspulver weitgehend temperaturunabhängig abbrennt.When using the DNDA propellant charge powder, this additional electrical energy can be omitted since the DNDA propellant charge powder burns off largely independently of temperature.

Zum Verschießen der Patrone 1 wird der Schalter 2 geschlossen und die mit einer Reihe von aufgeladenen Kondensatoren bestückte Energiequelle (bei einer Spannung von z.B. 40 kV) innerhalb kurzer Zeit entladen. Der dabei auftretende Entladestrom führt zur elektrischen Explosion der Drähte 11-13 und zur Einleitung von Lichtbogenentladungen innerhalb der Anzündverstärkungsröhren 14-16. Die Röhren werden durch die Lichtbögen angezündet und schlagartig umgesetzt. Die dabei entstehenden Treibladungsgase sowie die freigegebene Lichtbogenstrahlung bewirken dann eine schnelle und gleichmäßige Anzündung des in der Hülse befindlichen Treibladungspulvers 4, welches sich zusammen mit der verbrennbaren Hülse 5 daraufhin umsetzt.To shut off the cartridge 1, the
Durch die einem NENA-Treibladungspulver 4 über das Plasmaanzündsystem zugeführte elektrische Energiemenge ergibt sich außerdem eine Kompensation des Einflusses der Temperatur des Treibladungspulvers auf die Abbrandgeschwindigkeit, so daß ein aus der entsprechenden Rohrwaffe zu verschießendes Geschoß eine konstante Mündungsgeschwindigkeit aufweist, ohne daß der maximal zulässige Gebrauchsgasdruck überschritten wird.By the amount of electrical energy supplied to a NENA
Eine derartige Temperaturkompensation mit Hilfe von elektrischer Energie kann bei Verwendung eines temperaturunabhängigen DNDA-Treibladungspulvers entfallen. Hierdurch wird die für das Plasmaanzündsystem bereitzustellende elektrische Energiemenge verkleinert.Such temperature compensation by means of electrical energy can be omitted when using a temperature-independent DNDA propellant charge powder. As a result, the amount of electrical energy to be provided for the plasma ignition system is reduced.
