Description

Die Erfindung bezieht sich auf ein Treibladungspulver für Rohrwaffen nach dem Oberbegriff des Anspruchs 1.The invention relates to a propellant powder for tubular weapons according to the preamble of claim 1.

Die DE 35 00 068 C1 betrifft ein ein- oder mehrbasiges Treibladungspulver unter Einsatz von 0,0 Dioxy-azobenzol zur Verbesserung der mechanischen Eigenschaften bis - 55 °C. Aussagen über Temperaturkoeffizienten werden nicht getroffen. Es wird auch keine Diaza-Verbindung eingesetzt.DE 35 00 068 C1 relates to a single- or multi-base propellant powder using from 0.0 dioxy-azobenzene to improve the mechanical properties - 55 ° C. No statements about temperature coefficients are made. It will also no Diaza connection used.

In der DE 33 16 676 C2 ist eine Treibstoffzusammensetzung auf der Basis von Nitrocellulose mit Hexogen, einem Sprengöl und Weichmacher sowie Nitroglycerin beschrieben. Eine Diaza-Verbindung ist jedoch nicht erwähnt und es werden auch keine Aussagen über Temperaturkoeffinzienten getroffen.DE 33 16 676 C2 describes a fuel composition based on nitrocellulose with hexogen, an explosive oil and plasticizer and nitroglycerin. However, a Diaza connection is not mentioned and neither will be Statements made about temperature coefficients.

Die DE 30 33 519 C2 betrifft einen Raketentreibstoff für einen üblicherweise niedrigen Druckbereich beim Abbrand. Aussagen über den für Treibladungspulver relevanten Druckbereich über 3000 bar werden nicht gemacht. Zwar werden Hinweise über mechanische Eigenschaften in einem großen Temperaturbereich angedeutet. Es liegen jedoch keine Aussagen über Temperaturkoeffizienten, Abhängigkeit des Gasdruckes von den Temperaturen des Treibladungspulvers vor. Der im Anspruch angegebene energetische Weichmacher ist Sprengöl wie Ngl jedoch keine Diaza-Verbindung.DE 30 33 519 C2 relates to a rocket fuel for a usually low one Burning pressure area. Statements about the relevant for propellant powder Pressure ranges over 3000 bar are not made. There are references to mechanical Properties indicated in a wide temperature range. There are however no statements about temperature coefficients, dependence of the gas pressure from the temperatures of the propellant powder. The specified in the claim Energetic plasticizer is explosive oil like Ngl but not a diaza compound.

Bei einem weiteren bekannten Treibladungspulver entsprechend der DE 22 60 259 A handelt es sich um einen Treibsatz für Raketen und nicht um eine Treibladung für Rohrwaffen. Diese Treibladung ist, wie generell alle zweibasigen Treibmittel stark temperaturabhängig im interessierenden Temperaturbereich.In another known propellant powder according to DE 22 60 259 A it is a propellant charge for rockets and not a propellant charge for Gun. This propellant charge, like all dibasic propellants in general strongly temperature-dependent in the temperature range of interest.

In der US 4,567,296 A wird ein energetischer Weichmacher auf der Basis:einer fluorhaltigen Aza-Verbindung beschrieben. Diese Aza-Verbindung, nämlich das 1-Fluoro-1,1,5-Trinitro-3-oxa-5-azahexan ist für Rohrwaffen- und Treibladungspulver-Einsatz nicht geeignet. Beim Abbrand in einer Waffe wird der Stahl zersetzt, insbesondere bei den üblicherweise hohen Drücken und Temperaturen. Weiterhin bereitet diese Verbindung ein großes Entsorgungsproblem. Das Ausgangsmaterial 2-Nitro-2-aza-1 pro-panol unterscheidet sich chemisch grundlegend von den erfindungsgemäßen Dinitro-diaza-Verbindungen.In US 4,567,296 A an energetic plasticizer is based on: one fluorine-containing aza compound. This aza connection, that is 1-Fluoro-1,1,5-trinitro-3-oxa-5-azahexane is for use with barrel weapons and propellant powder not suitable. When it burns in a weapon, the steel decomposes, especially at the usually high pressures and temperatures. Furthermore, this connection creates a major disposal problem. The source material 2-Nitro-2-aza-1 pro-panol differs fundamentally chemically of the dinitro-diaza compounds according to the invention.

Ein besseres plastifizierbares Treibladungspulver beruht nach der US-A-4,457,791 auf einem Weichmacher DMMD. Weitere Weichmacher als Zusätze zu dem genannten liegen nicht vor. Ein Hinweis, dass der Temperaturkoeffizient beim Abbrand positiv beeinflusst wird, geht nicht hervor. A better plasticizable propellant powder is based on US-A-4,457,791 on a plasticizer DMMD. Other plasticizers as additives too the above are not available. An indication that the temperature coefficient is positively influenced during the burn, does not emerge.

Infolge der Temperaturabhängigkeit der Abbrandgeschwindigkeit des Treiblandungspulvers ist der beim Verschuss von Munition mit herkömmlichen ein- und mehrbasigen Treibladungspulver aus einer Rohrwaffe im Ladungsraum der Waffe eintretende maximale Gasdruck und damit auch die Geschossgeschwindigkeit ebenfalls stark temperaturabhängig.As a result of the temperature dependence of the burning rate of the propellant landing powder is the one when firing ammunition with conventional one and multi-base propellant powder from a barrel weapon in the loading space of the weapon entering maximum gas pressure and thus also the bullet speed also strongly temperature dependent.

Der Druck und die Geschwindigkeit der 120mm KE-Munition steigen von - 40°C nach + 50°C um ca. 1.500 bar und 165 m/s an, das sind 10 % der Sollgeschwindigkeit bei Normaltemperatur von + 21°C. Aufgrund dessen kann einerseits der Waffengebrauchsgasdruck bei Normaltemperatur nicht ausgeschöpft werden, was eine höhere Geschwindigkeit zur Folge hätte, und andererseits ist wegen der nur ungenau bekannten aktuellen Geschossanfangsgeschwindigkeit die Treffwahrscheinlichkeit deutlich verringert bzw., es müssen Maßnahmen getroffen werden, die aktuelle Geschossgeschwindigkeit zu ermitteln, um keinen Verlust an Treffgenauigkeit zu erleiden.The pressure and speed of the 120mm KE ammunition increase from - 40 ° C after + 50 ° C at approx. 1,500 bar and 165 m / s, which is 10% of the target speed at normal temperature of + 21 ° C. Because of this, the Gun service gas pressure at normal temperature can not be exhausted what would result in a higher speed, and on the other hand because of the only inaccurately known current floor start velocity the probability of hitting significantly reduced or, measures must be taken determine the current floor speed to avoid loss of accuracy to suffer.

Der Erfindung liegt die Aufgabe zugrunde, ein Treibladungspulver für Rohrwaffen vorzuschlagen, das einen kleinen Temperaturkoeffizient in dem Temperaturbereich von - 50°C bis + 70°C aufweist, so dass dadurch die genannten ballistischen Werte Maximaldruck und Geschossgeschwindigkeit nur wenig von der Pulvertemperatur abhängen.The invention has for its object a propellant powder for guns propose that a small temperature coefficient in the temperature range from - 50 ° C to + 70 ° C, so that the ballistic mentioned Values maximum pressure and bullet speed only a little of that Depending on the powder temperature.

Diese Aufgabe löst die Erfindung entsprechend den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is achieved by the invention in accordance with the characterizing features of claim 1. Advantageous further developments of the invention are the dependent claims refer to.

Die Erfindung ermöglicht aufgrund der Verwendung eines besonderen Weichmachers die Herstellung und den Einsatz von Treibladungspulver mit kleinem Temperaturkoeffizient. Das heißt: Ein derartiges Treibladungspulver ermöglicht den Verschuß von Rohrwaffenmunition mit nahezu konstanten Werten von Maximaldruck und Geschoßgeschwindigkeit im gesamten Temperaturbereich von - 50°C bis + 70°C.The invention enables due to the use of a special plasticizer the production and use of propellant powder with a low temperature coefficient. That means: such a propellant powder enables the firing of Gun ammunition with almost constant values of maximum pressure and bullet speed in the entire temperature range from - 50 ° C to + 70 ° C.
