Description

Die Erfindung betrifft eine Patrone mit elektrothermischer Anzündvorrichtung.The invention relates to a cartridge with an electrothermal igniter.

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 powders, especially with NENA propellant powder (NENA = N- (2-nitroxy) -nitramineethane) or DNDA propellant powder (DNDA = Dinitro-Diaza-Alkane), can significantly higher acceleration performance from Rifles can be fired at projectiles than with conventional propellant powders. As a rule, the shot gas temperature of such propellant powder and thus pipe erosion is also lower than with known powders. The high activation energy however, the high-energy propellant powder complicates the ignition With the help of pyrotechnic charges. The reduced willingness to ignite the Propellant powder also leads to an increase in ignition delay times and an increased spread of 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 safely and quickly ignite a cartridge, e.g. with NENA propellant powder, To ensure it has proven to be advantageous instead of a pyrotechnic Ignition charge to use an electrothermal igniter. Thereby becomes Ignition of the propellant powder in the bottom area of the corresponding cartridge such a high current flowed through a wire-shaped conductor that it exploded evaporates and creates an energetic arc. The arc then ignites the corresponding propellant 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, such an electrothermal Igniter also the relatively large temperature dependence of NENA propellant powder, which leads to a corresponding dependence of the acceleration performance leads, about the amount of electrical supplied to the plasma ignition system Energy to 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 of this electrothermal ignition device has proven, however, that initially only a relatively small amount due to the generation of the arc at the bottom Percentage of propellant powder is ignited and especially when heavy ignitable propellant powders often no reproducible burning behavior of the Propellant powder results.

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 powder, in proposed the unpublished German patent application DE 199 21 379.8, not lead the wire-shaped conductors directly through the propellant charge, but to be arranged inside tubes also consisting of propellant powder. These propellant powder tubes then form ignition channels within the propellant charge structure. When the ignition device is activated, the wire-shaped evaporates first An arc plasma channel is formed in the conductor and inside the respective propellant powder tubes. The energy is transferred via the plasma channels via radiation transport mechanisms released to the environment. This release of energy leads to rapid ignition of the propellant powder tubes and their fragmentation. The burning fragments (hot spots) of the propellant powder tubes and the released arc radiation cause the propellant charge to ignite quickly and evenly.

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 shown that when using propellant powder tubes made of graphitized Propellant powder, as is usually commercially available, is a relatively high one Electrical energy requirement is required to ensure adequate ignition interaction to achieve with the propellant powder.

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 unpublished DE 199 21 379.8, the invention lies The task is to specify a cartridge in which propellant powder, which is difficult to ignite, especially NENA or DNDA propellant powder, quickly and safely are ignitable, the need for electrical energy should be as low as possible.

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. More beneficial Embodiments of the invention disclose the subclaims.

Im wesentlichen liegt der Erfindung der Gedanke zugrunde, transparente Treibladungspulver-Röhren zu verwenden. Dabei hat sich als Treibladungspulver besonders Nitrocellulose-Pulver als geeignet erwiesen, und zwar insbesondere das unter der Bezeichnung JA2 bekannte Treibladungspulver. 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 of transparent propellant powder tubes to use. Nitrocellulose powder in particular has proven to be a propellant charge powder proven to be suitable, in particular that known under the name JA2 Propellant powder. So that this propellant powder is transparent, it must not Contain soot and the usual graphitization of the outer surface must be omitted.

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 of the Plasma channels emit radiation without large absorption losses to build up the propellant charge the cartridge. In addition, the plasma radiation produces a change in the erosion-effective surface of the transparent propellant powder tubes leading to a much faster implementation of the tubes and thus to support the ignition process leads. The exploitation of these properties has a significant reduction the electrical energy requirements 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.It has also been shown that when using optically transparent propellant powder tubes the need for additional electrical energy for temperature compensation of NENA propellant powder compared to the need for non-transparent tubes is reduced.

Bei Anwendung des DNDA-Treibladungspulvers kann diese zusätzliche elektrische Energie entfallen, da das DNDA-Treibladungspulver weitgehend temperaturunabhängig abbrennt.When using the DNDA propellant powder, this can generate additional electrical energy omitted, since the DNDA propellant powder burns largely independent of temperature.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus dem folgenden anhand von Figuren erläuterten Ausführungsbeispiel. Es zeigen:

  • Fig.2 eine vergrößerte Darstellung des Querschnittes durch die in Fig. 1 dargestellte Patrone entlang der dort mit II-II bezeichneten Linie.
    • Further details and advantages of the invention result from the following exemplary embodiment explained with reference to figures. Show it:
  • 1 shows the longitudinal section through an embodiment of a cartridge according to the invention with three ignition channels and
  • 2 shows an enlarged representation of the cross section through the cartridge shown in FIG. 1 along the line labeled II-II there.

    • In Fig.1 ist mit 1 eine großkalibrige Patrone (z.B. zum Verschießen aus einer Panzerwaffe) bezeichnet, die zur Zündung über einen Schalter 2 mit einer Stromquelle 3 verbunden ist. Die entsprechende Waffe, in der sich die Patrone 1 befindet, wurde aus Übersichtlichkeitsgründen nicht dargestellt. In Fig. 1, 1 is a large-caliber cartridge (e.g. for firing from an armored weapon) referred to, which is connected to a current source 3 for ignition via a switch 2. The corresponding weapon in which the cartridge 1 is located has been used for reasons of clarity not shown.

    Die Patrone 1 umfaßt eine mit NENA-oder DNDA-Treibladungspulver 4 gefüllte verbrennbare Hülse 5 und einen die Treibladungshülse 5 bodenseitig abschließenden aus Metall bestehenden Hülsenboden 6. Die verbrennbare Hülse 5 ist im Bereich ihres hülsenbodenseitigen Endes 7 formschlüssig zwischen einem Isolierformteil 8 und dem Hülsenboden 6 fixiert.The cartridge 1 comprises a combustible filled with NENA or DNDA propellant powder 4 Sleeve 5 and a bottom of the propellant charge sleeve 5 made of metal existing sleeve bottom 6. The combustible sleeve 5 is in the region of its sleeve bottom End 7 positively between an insulating molded part 8 and the sleeve bottom 6 fixed.

    In dem Hülsenboden 6 ist mittig eine gegenüber diesem elektrisch isolierte Hochspannungselektrode 9 angeordnet, die durch das Isolierformteil 8 hindurchgeführt und mit einer als Stromverteiler wirkenden Metallscheibe 10 verbunden ist.In the middle of the sleeve base 6 is a high-voltage electrode which is electrically insulated from it 9 arranged, which passed through the molded insulating part 8 and with a metal disk 10 acting as a current distributor is connected.

    An dem Stromverteiler 10 sind drei elektrisch leitende Drähte 11-13 befestigt, die jeweils axial durch eine aus transparentem JA2-Treibladungspulver bestehende Röhre 14-16 hindurchgeführt (Fig.2) und im Bereich des Hülsendeckels 17 der Treibladungshülse 5 mit einem ringförmigen Kontaktteil 18 verbunden sind. Das Kontaktteil 18 kontaktiert seinerseits die auf Erdpotential liegende Innenwand der nicht dargestellten Waffe.On the power distributor 10, three electrically conductive wires 11-13 are attached, each axially through a tube 14-16 made of transparent JA2 propellant powder (Fig.2) and in the area of the sleeve cover 17 of the propellant charge sleeve 5 with an annular contact part 18 are connected. The contact part 18 contacts in turn the inner wall of the weapon, not shown, which is at ground potential.

    Die transparenten Treibladungspulver-Röhren 14-16 sind mit mehreren, über Länge und Umfang verteilt angeordneten radialen Öffnungen 19 versehen.The transparent propellant powder tubes 14-16 are of several lengths and lengths Provided circumferentially distributed radial openings 19.

    Der Ladungsaufbau kann sowohl als Schüttladung als auch als Stapel- oder Kompaktladung ausgeführt werden.The charge build-up can be used as a bulk load as well as a stacked or compact load be carried out.

    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 Treibladungspulver-Röhren 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 shoot the cartridge 1, the switch 2 is closed and the one with a row energy source equipped with charged capacitors (at a voltage of e.g. 40 discharged within a short time. The discharge current that occurs leads to electrical Explosion of wires 11-13 and initiation of arcing within propellant powder tubes 14-16. The tubes are ignited by the arcs and implemented suddenly. The resulting propellant gases and the released arc radiation then causes a quick and even ignition of the propellant powder 4 located in the sleeve, which together with the combustible sleeve 5 is then implemented.

    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.Through the supplied to a NENA propellant powder 4 via the plasma ignition system electrical energy quantity also results in a compensation of the influence of Temperature of the propellant powder to the burn rate, so that from the corresponding barrel weapon to be fired projectile a constant muzzle velocity has without the maximum permissible service gas pressure being exceeded becomes.

    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 using electrical energy can be used of a temperature-independent DNDA propellant powder. Hereby the amount of electrical energy to be provided for the plasma ignition system is reduced.
