Definitions
- Propellants for projectiles are usually made of high-energy substances such as e.g. Nitrocellulose or more thermally stable systems, e.g. designed for automotive safety in the form of gas sets and are in use. These versions are gas rich and produce the energy needed to perform the projectile motion through rapid and near-completion. Thermodynamically, this is expressed by the oxygen balance, the specific energy or by the heat of explosion. Such versions are only partially suitable for weapons training systems, as they accelerate the training projectile too much.
- the propellant charge according to the invention contains, in addition to per se customary heavy metal-free igniters, frictional agents and preferably no oxidants and / or reducing agents.
- the friction agent also serves as an inert diluent and does not constitute a reaction component.
- Friction agents according to the invention used are those which exert no abrasive action on the weapon side (soft friction agents). These friction agents are selected from the group of marble, calcite, dolomite and / or soft carbonates such as magnesium carbonate and / or calcium carbonate and / or mixtures thereof.
- the propellant charge according to the invention also other conventional friction agents can be added in conventional amounts.
- heavy metal-free igniters impact-sensitive explosives are used. Examples include potassium dinitrobenzofuroxanate and tetrazene. It is known to use Kaliumdinitrobenzofuroxanat and tetracene as components in heavy metal-free igniter sets, but then mostly in the presence of oxidizing and reducing agents.
- Kaliumdinitrobenzofuroxanat and tetracene is less suitable as a propellant charge for training systems.
- inventive sentence waived the presence of reducing agents. As a result, the additional surcharges no longer act as oxidizing agents.
- the kinetic energy of the projectile can be controlled for all types of weapons by varying the recipe of the propellant charge of the invention within wide limits. As a result, the above-described excessive acceleration of the training projectile is avoided.
- the impact-sensitive propellant charges according to the invention can be labored in conventional primer caps. However, the primers then serve not to ignite a propellant powder, but form even the gas generating set. The primers containing the propellant charges according to the invention can then be ignited, for example, by a primary primer.
- the impact-sensitive propellant charges according to the invention contain from 5 to 70% by weight, preferably from 10 to 65% by weight, of heavy metal-free igniters, it also being possible to use mixtures of these heavy metal-free igniters.
- the friction agent according to the invention is used in amounts of from 30 to 95% by weight, preferably in amounts of from 35 to 80% by weight, it also being possible according to the invention to use mixtures of these friction agents.
- compositions may be mentioned: Power: weak medium strongly potassium dinitrobenzofuroxanate 20% by weight 40% by weight 50% by weight tetracene 0% by weight 10% by weight 15% by weight soft friction agent 80% by weight 50% by weight 35% by weight
- the propellant charges according to the invention can be used in weapon training systems.

Description
- Treibladungen für Geschosse bestehen in der Regel aus energiereichen Stoffen wie z.B. Nitrocellulose oder thermisch stabileren Systemen, wie sie z.B. für die Kraftfahrzeugsicherheit in Form von Gassätzen entwickelt wurden und sich im Einsatz befinden. Diese Versionen sind gasreich und erzeugen die zur Verrichtung der Geschossbewegung nötige Energie durch schnelle und nahezu vollständige Umsetzung. Thermodynamisch kommt dies durch die Sauerstoffbilanz, die spezifische Energie bzw. durch die Explosionswärme zum Ausdruck. Solche Versionen sind für Waffen-Übungssysteme nur bedingt geeignet, da sie das Übungsgeschoss zu stark beschleunigen.
- Die erfindungsgemäße Treibladung enthält neben an sich üblichen schwermetallfreien Anzündstoffen Friktionsmittel und vorzugsweise keine Oxidations- und/oder Reduktionsmittel. Das Friktionsmittel dient gleichzeitig als inertes Verdünnungsmittel und stellt keine Reaktionskomponente dar. Als erfindungsgemäße Friktionsmittel werden solche eingesetzt, die keine abrasive Wirkung auf Waffenteite ausüben (weiche Friktionsmittel). Diese Friktionsmittel werden aus der Gruppe Marmor, Calcit, Dolomit und/oder weiche Carbonate wie Magnesiurncarbonat und/oder Calciumcarbonat und/oder Mischungen daraus ausgewählt.
- Gegebenenfalls können der erfindungsgemäßen Treibladung auch andere herkömmliche Friktionsmittel in üblichen Mengen zugemischt werden. Als schwermetallfreie Anzündstoffe werden schlagempfindliche Explosivstoffe eingesetzt. Beispielhaft genannt seien Kaliumdinitrobenzofuroxanat und Tetrazen. Es ist bekannt, Kaliumdinitrobenzofuroxanat und Tetrazen als Komponenten in schwermetallfreien Anzündsätzen einzusetzen, jedoch dann meist in Anwesenheit von Oxidations- und Reduktionsmitteln. Ein solcher normaler Anzündsatz, bestehend aus den zuvor beschriebenen Komponenten mit Oxidations- und Reduktionsmitteln ist als Treibladung für Übungssysteme weniger geeignet. Im Gegensatz zum Stand der Technik wird im erfindungsgemäßen Satz auf die Anwesenheit von Reduktionsmitteln verzichtet. Dadurch wirken die weiteren Zuschläge nicht mehr als Oxidationsmittel.
- Die kinetische Energie des Geschosses lässt sich für alle Waffentypen durch Variation der Rezeptur der erfindungsgemäßen Treibladung in weiten Grenzen steuern. Dadurch wird die eingangs beschriebene zu starke Beschleunigung des Übungsgeschosses vermieden.
- Die erfindungsgemäßen schlagempfindlichen Treibladungen können in herkömmlichen Anzündhütchen laboriert werden. Die Anzündhütchen dienen dann jedoch nicht dazu, ein Treibladungspulver anzuzünden, sondern bilden selbst den gaserzeugenden Satz. Die die erfindungsgemäßen Treibladungen enthaltenden Anzündhütchen können dann beispielsweise durch ein primäres Zündhütchen angezündet werden.
- Die erfindungsgemäßen schlagempfindlichen Treibladungen enthalten 5 bis 70 Gew.-%, vorzugsweise 10 bis 65 Gew.-% schwermetallfreie Anzündstoffe enthalten, wobei erfindungsgemäß auch Mischungen dieser schwermetallfreien Anzündstoffe eingesetzt werden können. Das erfindungsgemäße Friktionsmittel wird in Mengen von 30 bis 95 Gew.-%, vorzugsweise in Mengen von 35 bis 80 Gew.-% eingesetzt, wobei erfindungsgemäß auch Mischungen dieser Friktionsmittel eingesetzt werden können.
- Durch Variation der Satzzusammensetzung lassen sich Treibladungs-Leistungen aller gewünschten Stärken realisieren.
- Dabei wurden folgende positive Beobachtungen gemacht:
- keine Aerosolbildung;
- keine Waffenerosion durch weiches Friktionsmittel;
- dennoch ausreichende Friktionswirkung;
- gleichmäßige Leistungseinstellung möglich.
- Beispielhaft genannt seien folgende Zusammensetzungen:
Leistung: schwach mittel stark Kaliumdinitrobenzofuroxanat 20 Gew.-% 40 Gew.-% 50 Gew.-% Tetrazen 0 Gew.-% 10 Gew.-% 15 Gew.-% weiches Friktionsmittel 80 Gew.-% 50 Gew.-% 35 Gew.-% - Verwendet werden können die erfindungsgemäßen Treibladungen in Waffen-Übungssystemen.
