- the invention relates to propellant charges from propellant charge powders whose energy sources are nitrocelluloses or nitrocelluloses and explosive oils or nitrocelluloses, explosive oils, nitroguanidine and / or hexogen, octogen, i.e. from propellant powders, which are referred to as one, two or three-base propellant powder.
- Propellant powder of these compositions can be manufactured as a full strand, perforated or tube powder.
- Single-base propellant powders must be prepared with suitable solvents such as ether, alcohol, acetone to gelatinize the nitrocelluloses.
- suitable solvents such as ether, alcohol, acetone to gelatinize the nitrocelluloses.
- two- and three-base propellant powder can be manufactured without solvents. They are called PoL powder.
- the surface treatment that may be used for bulk powders can be disregarded in this consideration.
- a characteristic of "homogeneous powders” is that their burning speed increases with increasing bombardment or ambient temperatures. This has the consequence that in the case of propellant charges made of “homogeneous powders” in the weapon bombardment, the projectile speeds at a bombardment temperature of e.g. - 40 ° C are significantly lower than at a bombardment temperature of e.g. + 60 ° C.
- the temperature-dependent performance of the propellant charges has considerable disadvantages, e.g. in terms of first hit accuracy and bullet performance, which is due to the high temperatures of e.g. Weapon pressure occurring at + 60 ° C is limited.
- Propellant powders that do not have the characteristic increase in burning speeds with increasing temperatures which are highlighted for "homogeneous powder" are described in DE-PS 17 71 087, DE-PS 20 42 457 and DE-OS 30 08 196.
- the energy sources of these propellant powders are the same as for the classic "homogeneous powders".
- the decisive difference is the material structure of the powder mass.
- One-, two- or three-base bulk powder, called granulate suitable dimensions are e.g. incorporated into the plasticine, known as the base, of a single-base propellant powder.
- the degree of nitration of the nitrocelluloses used to produce the granules and base material is such that the granules are retained as granules in the course of the production of these powders.
- HET powder Because of the materially heterogeneous structure in the powder grain, which is given by embedding a granulate in a powder base, these powder types are called "HET powder”.
- HET powders have a fundamentally different temperature dependency than “homogeneous powders”. With increasing bombardment temperatures their burning speed decreases.
- the "negative" temperature dependence of the burning rate in HET powders is probably explained by the fact that the bond between the base material and the granulate is temperature-dependent. Is e.g. the basic material is single-base and the granulate is double-base, the bond strengthens with increasing temperatures due to the expansion of the thermoplastic granulate in the comparatively rigid basic material. As a result, the focal area formed in the grain becomes smaller. At sub-zero temperatures, larger firing surfaces form in the powder grain due to the greater contraction of the granules. Due to the enlargement of the focal areas at sub-zero temperatures and the reduction of the focal areas at increasing temperatures, the inherent drop in the burning rate with falling temperature is at least down to a certain, low bombardment temperature of e.g. - 15 ° C, overcompensated for an increase.
- a certain, low bombardment temperature e.g. - 15 ° C
- HET powders that burn off in a temperature-neutral manner would be advantageous. However, this cannot be achieved with the known powder types in a larger bombardment temperature range of several tens of degrees Celsius with the specification of heat of explosion, force and propellant powder dimensions.
- propellant charges are obtained in a surprisingly simple manner with a combustion behavior which is temperature-neutral over a large bombardment temperature range or can be influenced in a targeted manner as a function of temperature by one or more material-homogeneous propellant charge powders (“homogeneous powder”) with one or more material-inhomogeneous propellant charge powders (“HET- Powder ”) mixes to form the propellant charge.
- homogeneous powder material-homogeneous propellant charge powders
- HET- Powder material-inhomogeneous propellant charge powders
- combustion behavior which can be specifically influenced in the temperature dependency should take into account here that occasionally a weapon pressure drop is deliberately sought at extremely low firing temperatures in order to have security against an accidental increase in weapon pressure due to powder embrittlement occurring at extremely low temperatures. Likewise, a drop in weapon pressure occurring at a comparatively high and therefore rarely or not at all occurring firing temperature may also be acceptable. It is essential that with the measure according to the invention, by appropriate choice of the powder types used for the mixture and their mixing ratio, the combustion behavior of the finished propellant charge can easily be determined in such a way that the combustion parameters such as weapon pressure and projectile speed are approximately constant over a larger nominal firing temperature range and in any case, do not become larger outside the nominal range.
- 1 and 2 show the measured values for weapon pressure and projectile speed obtained on a 2 cm machine gun in the bombardment temperature range between -40.degree. C. and + 60.degree.
- Part A shows the projectile speeds measured at 16 m weapon distance
- part B the measured weapon pressures.
- An adapted "HET powder” is developed for a “homogeneous powder” that is used in a type of ammunition to build up the propellant charge. This means that the heat of explosion, the force and the dimensions of the "HET powder” can be set to the same or comparable values as for the "homogeneous powder” by appropriate choice of basic composition and granulate composition and quantity of granulate.
- the HET powder " is adapted to the" homogeneous powder "in such a way that for a reference value of the bombardment temperature of, for example, - 5 to - 10 ° C in the weapon bombardment, the same projectile speed with the same or comparable pressure curve for the from" homogeneous "or If this is the case, the pressure and speed curves of the two powders are mirror-inverted to one another after rising and falling bombardment temperatures.
- propellant charge is built up from a mixture of equal parts by weight of "homogeneous” and this "HET powder" adapted in the above manner, weapon pressure and projectile speed remain at the firing temperature range from - 40 ° C to + 60 ° C practically constant.

Abstract
Description
Treibladung für Rohrwaffen und Verfahren zu ihrer Herstellung.Propellant charge for barrel weapons and process for their manufacture.
Die Erfindung bezieht sich auf Treibladungen aus Treibladungspulvern, deren Energieträger Nitrocellulosen oder Nitrocellulosen und Sprengöle oder Nitrocellulosen, Sprengöle, Nitroguanidin und/oder Hexogen, Oktogen sind, d.h. aus Treibladungspulvern, die als ein-, zwei- bzw. dreibasige Treibladungspulver bezeichnet werden.The invention relates to propellant charges from propellant charge powders whose energy sources are nitrocelluloses or nitrocelluloses and explosive oils or nitrocelluloses, explosive oils, nitroguanidine and / or hexogen, octogen, i.e. from propellant powders, which are referred to as one, two or three-base propellant powder.
Treibladungspulver dieser Zusammensetzungen können als Vollstrang, Loch- oder Röhrenpulver gefertigt werden. Einbasige Treibladungspulver müssen zur Gelatinierung der Nitrocellulosen mit geeigneten Lösemitteln wie Äther, Alkohol, Aceton gefertigt werden. Zwei-und dreibasige Treibladungspulver können bei entsprechender Zusammensetzung ohne Lösemittel gefertigt werden. Sie werden PoL-Pulver genannt.Propellant powder of these compositions can be manufactured as a full strand, perforated or tube powder. Single-base propellant powders must be prepared with suitable solvents such as ether, alcohol, acetone to gelatinize the nitrocelluloses. With the appropriate composition, two- and three-base propellant powder can be manufactured without solvents. They are called PoL powder.
Für die Herstellung ein-, zwei- und dreibasiger Treibladungspulver gilt allgemein, daß alle Bestandteile bei der Fertigung bestens vermischt werden, so daß das fertige Pulver in seiner Grundmasse von homogener Zusammensetzung ist.For the manufacture of one-, two- and three-base propellant powders, it is generally the case that all components are mixed very well during manufacture, so that the finished powder has a homogeneous composition in its basic composition.
Die bei Schüttpulvern gegebenenfalls angewandte Oberflächenbehandlung kann bei dieser Betrachtung unberücksichtigt bleiben.The surface treatment that may be used for bulk powders can be disregarded in this consideration.
Diese allgemein in Rohrwaffen verwandten klassischen Treibladungspulver werden im Rahmen der vorliegenden Anmeldung als "Homogen-Pulver" bezeichnet.These classic propellant charge powders, which are generally used in tubular weapons, are referred to in the context of the present application as "homogeneous powder".
Charakteristikum der "Homogen-Pulver" ist, daß ihre Brenngeschwindigkeit mit steigenden Beschuß- bzw. Umgebungstemperaturen größer werden. Dies hat zur Folge, daß bei Treibladungen aus "Homogen-Pulvern" im Waffenbeschuß die Projektilgeschwindigkeiten bei einer Beschußtemperatur von z.B. - 40 °C erheblich kleiner sind als bei einer Beschußtemperatur von z.B. + 60 °C. Für Panzerkanonen hat die temperaturabhängige Leistung der Treibladungen erhebliche Nachteile z.B. im Hinblick auf Ersttreffsicherheit und Geschoßleistung, die durch den bei hohen Temperaturen von z.B. + 60 °C auftretenden Waffendruck begrenzt wird.A characteristic of "homogeneous powders" is that their burning speed increases with increasing bombardment or ambient temperatures. This has the consequence that in the case of propellant charges made of "homogeneous powders" in the weapon bombardment, the projectile speeds at a bombardment temperature of e.g. - 40 ° C are significantly lower than at a bombardment temperature of e.g. + 60 ° C. For tank cannons, the temperature-dependent performance of the propellant charges has considerable disadvantages, e.g. in terms of first hit accuracy and bullet performance, which is due to the high temperatures of e.g. Weapon pressure occurring at + 60 ° C is limited.
Treibladungspulver, die den für "Homogen-Pulver" herausgestellten charakteristischen Anstieg der Brenngeschwindigkeiten mit steigenden Temperaturen nicht aufweisen, sind in der DE-PS 17 71 087, der DE-PS 20 42 457 und der DE-OS 30 08 196 beschrieben.Propellant powders that do not have the characteristic increase in burning speeds with increasing temperatures, which are highlighted for "homogeneous powder", are described in DE-PS 17 71 087, DE-PS 20 42 457 and DE-OS 30 08 196.
Die Energieträger dieser Treibladungspulver sind die gleichen wie bei den klassischen "Homogen-Pulvern". Der entscheidende Unterschied besteht im stofflichen Aufbau der Pulvermasse.The energy sources of these propellant powders are the same as for the classic "homogeneous powders". The decisive difference is the material structure of the powder mass.
Ihre Herstellung verdeutlicht dies. Ein-, zwei- oder dreibasige Schüttpulver, Granulat genannt, geeigneter Abmessungen werden z.B. in die Knetmasse, Grundmasse genannt, eines einbasigen Treibladungspulvers eingearbeitet. Die zur Herstellung von Granulat und Grundmasse eingesetzten Nitrocellulosen sind im Nitrierungsgrad so gewählt, daß das Granulat im Herstellungsgang dieser Pulver als Granulat erhalten bleibt.This is illustrated by their manufacture. One-, two- or three-base bulk powder, called granulate, suitable dimensions are e.g. incorporated into the plasticine, known as the base, of a single-base propellant powder. The degree of nitration of the nitrocelluloses used to produce the granules and base material is such that the granules are retained as granules in the course of the production of these powders.
Wegen des stofflich heterogenen Aufbaus im Pulverkorn, der durch die Einbettung eines Granulates in eine Pulvergrundmasse gegeben ist, werden diese Pulvertypen "HET-Pulver" genannt.Because of the materially heterogeneous structure in the powder grain, which is given by embedding a granulate in a powder base, these powder types are called "HET powder".
"HET-Pulver" weisen eine grundsätzliche andere Temperaturabhängigkeit auf als "Homogen-Pulver". Mit steigenden Beschußtemperaturen nimmt ihre Brenngeschwindigkeit ab."HET powders" have a fundamentally different temperature dependency than "homogeneous powders". With increasing bombardment temperatures their burning speed decreases.
Die "negative" Temperaturabhängigkeit der Brenngeschwindigkeit bei HET-Pulvern findet wohl darin eine Erklärung, daß der Verbund zwischen Grundmasse und Granulat temperaturabhängig ist. Ist z.B. die Grundmasse einbasig und das Granulat zweibasig, wird bei steigenden Temperaturen durch die Ausdehnung des thermoplastischen Granulates in der vergleichsweise starren Grundmasse der Verbund stärker. Als Folge davon wird die im Korn sich ausbildende Brennfläche kleiner. Bei Minustemperaturen bilden sich durch die stärkere Granulatkontraktion größere Brennflächen im Pulverkorn aus. Durch die Vergrößerung der Brennflächen bei Minustemperaturen und die Minderung der Brennflächen bei ansteigenden Temperaturen wird der an sich gegebene Abfall der Brenngeschwindigkeit mit fallender Temperatur, mindestens bis herab zu einer gewissen, niedrigen Beschußtemperatur von z.B. - 15 °C, überkompensiert in einen Anstieg.The "negative" temperature dependence of the burning rate in HET powders is probably explained by the fact that the bond between the base material and the granulate is temperature-dependent. Is e.g. the basic material is single-base and the granulate is double-base, the bond strengthens with increasing temperatures due to the expansion of the thermoplastic granulate in the comparatively rigid basic material. As a result, the focal area formed in the grain becomes smaller. At sub-zero temperatures, larger firing surfaces form in the powder grain due to the greater contraction of the granules. Due to the enlargement of the focal areas at sub-zero temperatures and the reduction of the focal areas at increasing temperatures, the inherent drop in the burning rate with falling temperature is at least down to a certain, low bombardment temperature of e.g. - 15 ° C, overcompensated for an increase.
Faktoren, über die das Temperaturverhalten eines "HET-Pulvers"gesteuert werden kann, d.h. in welchem Maß die Brenngeschwindigkeit mit ansteigenden Temperaturen abfällt und mit abfallenden Temperaturen ansteigt, sind Zusammensetzung der Grundmasse und der Granulate, Granulatanteile und Granulatgrößen.Factors through which the temperature behavior of a "HET powder" can be controlled, i.e. To what extent the burning rate decreases with increasing temperatures and increases with decreasing temperatures are the composition of the basic mass and the granules, granulate proportions and granule sizes.
Vorteilhaft wären ganz temperaturneutral abbrennende "HET-Pulver. Dies ist aber in einem größeren Beschußtemperaturbereich von mehreren zehn Grad Celsius bei Vorgabe von Explosionswärme, Force und Treibladungspulverabmessungen mit den bekannten Pulvertypen nicht zu erreichen."HET powders that burn off in a temperature-neutral manner would be advantageous. However, this cannot be achieved with the known powder types in a larger bombardment temperature range of several tens of degrees Celsius with the specification of heat of explosion, force and propellant powder dimensions.
Erfindungsgemäß erhält man in überraschend einfacher Weise Treibladungen mit einem über einen großen Beschußtemperaturbereich temperaturneutralen oder in der Temperaturabhängigkeit gezielt beeinflußbaren Abbrandverhalten dadurch, daß man ein oder mehrere stofflich homogene Treibladungspulver ("Homogen-Pulver") mit einem oder mehreren stofflich inhomogenen Treibladungspulvern ("HET-Pulver") zur Bildung der Treibladung mischt.According to the invention, propellant charges are obtained in a surprisingly simple manner with a combustion behavior which is temperature-neutral over a large bombardment temperature range or can be influenced in a targeted manner as a function of temperature by one or more material-homogeneous propellant charge powders (“homogeneous powder”) with one or more material-inhomogeneous propellant charge powders (“HET- Powder ") mixes to form the propellant charge.
Mit dem Ausdruck "in der Temperaturabhängigkeit gezielt beeinflußbares Abbrandverhalten" soll hier berücksichtigt werden, daß gelegentlich ein Waffendruckabfall bei extrem niedrigen Beschußtemperaturen bewußt angestrebt wird, um eine Sicherheit gegen einen zufälligen Waffendruckanstieg aufgrund von bei extrem niedrigen Temperaturen auftretender Pulverversprödung zu haben. Ebenso kann gelegentlich ein bei vergleichsweise hoher und daher selten oder gar nicht vorkommender Beschußtemperatur eintretender Waffendruckabfall akzeptabel sein. Wesentlich ist, daß sich mit der erfindungsgemäßen Maßnahme durch entsprechende Wahl der zur Mischung verwendeten Pulvertypen und ihres Mischungsverhältnisses das Abbrandverhalten der fertigen Treibladung leicht so festlegen läßt, daß die Abbrand-Kenngrößen wie Waffendruck und Projektilgeschwindigkeit in einem größeren Beschußtemperatur-Nennbereich in etwa konstant sind und außerhalb des Nennbereiches jedenfalls nicht größer werden.The expression "combustion behavior which can be specifically influenced in the temperature dependency" should take into account here that occasionally a weapon pressure drop is deliberately sought at extremely low firing temperatures in order to have security against an accidental increase in weapon pressure due to powder embrittlement occurring at extremely low temperatures. Likewise, a drop in weapon pressure occurring at a comparatively high and therefore rarely or not at all occurring firing temperature may also be acceptable. It is essential that with the measure according to the invention, by appropriate choice of the powder types used for the mixture and their mixing ratio, the combustion behavior of the finished propellant charge can easily be determined in such a way that the combustion parameters such as weapon pressure and projectile speed are approximately constant over a larger nominal firing temperature range and in any case, do not become larger outside the nominal range.
Vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous embodiments of the invention emerge from the subclaims.
Im folgenden wird die Erfindung anhand von zwei Beispielen unter Bezugnahme auf die Figuren 1 und 2 näher erläutert.The invention is explained in more detail below with the aid of two examples with reference to FIGS. 1 and 2.
In den Figuren 1 und 2 sind die an einer 2 cm Maschinenwaffe erhaltenen Meßwerte für Waffendruck und Projektilgeschwindigkeit im Beschußtemperaturbereich zwischen - 40 °C und + 60 °C wiedergegeben. Teil A zeigt jeweils die in 16 m Waffenentfernung gemessenen Projektilgeschwindigkeiten, Teil B die gemessenen Waffendrücke.1 and 2 show the measured values for weapon pressure and projectile speed obtained on a 2 cm machine gun in the bombardment temperature range between -40.degree. C. and + 60.degree. Part A shows the projectile speeds measured at 16 m weapon distance, part B the measured weapon pressures.
Zu einem "Homogen-Pulver", das in einer Munitionsart zum Aufbau der Treibladung eingesetzt ist, wird ein angepaßtes "HETPulver" entwickelt. Dies bedeutet, daß Explosionswärme, Force und Abmessung des "HET-Pulvers" durch entsprechende Wahl von Grundmassen- und Granulatzusammensetzung sowie Granulatmenge auf gleiche oder vergleichbare Werte wie beim "Homogen-Pulver" eingestellt werden. Das HET-Pulver" wird dem "Homogen-Pulver" dabei so angepaßt, daß sich für einen Bezugswert der Beschußtemperatur von z.B. - 5 bis - 10 °C im Waffenbeschuß gleiche Projektilgeschwindigkeit bei gleichem oder vergleichbarem Druckverlauf für die aus "Homogen-" bzw. "HET-Pulver" aufgebauten Treibladungen ergeben. Ist dies erfüllt, sind die Druck- und Geschwindigkeitskurven der beiden Pulver nach steigenden und fallenden Beschußtemperaturen zueinander spiegelbildverkehrt.An adapted "HET powder" is developed for a "homogeneous powder" that is used in a type of ammunition to build up the propellant charge. This means that the heat of explosion, the force and the dimensions of the "HET powder" can be set to the same or comparable values as for the "homogeneous powder" by appropriate choice of basic composition and granulate composition and quantity of granulate. The HET powder "is adapted to the" homogeneous powder "in such a way that for a reference value of the bombardment temperature of, for example, - 5 to - 10 ° C in the weapon bombardment, the same projectile speed with the same or comparable pressure curve for the from" homogeneous "or If this is the case, the pressure and speed curves of the two powders are mirror-inverted to one another after rising and falling bombardment temperatures.
Wird die Treibladung aus einer Mischung gleicher Gewichtsanteile an "Homogen-" und diesem in obiger Weise angepaßten "HET-Pulver" aufgebaut, bleiben Waffendruck und Projektilgeschwindigkeit im Beschußtemperaturbereich von - 40 °C bis + 60 °C praktisch konstant.If the propellant charge is built up from a mixture of equal parts by weight of "homogeneous" and this "HET powder" adapted in the above manner, weapon pressure and projectile speed remain at the firing temperature range from - 40 ° C to + 60 ° C practically constant.
In Figur 1 geben die mit 1 bezeichneten Kurven die Werte für Waffendruck und Projektilgeschwindigkeit wieder, die mit dem für diese Munition eingeführten "Homogen-Treibladungspulver" erhalten wurden. Die mit 2 bezeichneten Kurven geben die Werte wieder, die mit dem angepaßten "HET-Pulver" erhalten wurden. Die mit 3 bezeichneten Kurven geben die Werte wieder, die mit einer Mischung gleicher Gewichtsanteile beider Pulver erhalten wurden.In FIG. 1, the curves labeled 1 represent the values for weapon pressure and projectile speed which were obtained with the "homogeneous propellant powder" introduced for this ammunition. The curves labeled 2 represent the values obtained with the adjusted "HET powder". The curves denoted by 3 represent the values obtained with a mixture of the same weight fractions of both powders.
Es unterscheidet sich vom Beispiel 1 dadurch, daß das eingesetzte "HET-Pulver" so aufgebaut wurde, daß von dem Bezugswert 0 °C der Beschußtemperatur der Waffendruck nach höheren wie auch nach tieferen Temperaturen abfällt.It differs from Example 1 in that the "HET powder" used was constructed in such a way that the weapon pressure drops from higher and lower temperatures from the reference value of 0 ° C. to the bombardment temperature.
In Figur 2 geben die mit 1 bezeichneten Kurven wieder die Werte des "Homogen-Pulvers", die mit 2 bezeichneten Kurven die Werte des "HET-Pulvers" und die mit 3 bezeichneten Kurven die Werte wieder, die mit einer Mischung gleicher Gewichtsanteile beider Pulver erhalten wurden.In FIG. 2, the curves labeled 1 again represent the values of the "homogeneous powder", the curves labeled 2 represent the values of the "HET powder" and the curves labeled 3 represent the values obtained with a mixture of the same proportions by weight of both powders were obtained.
