Description

Die Erfindung betrifft ein Munitionsprüfgerät insbesondere für Mittelkaliber-Munition.The invention relates to a Munitionsprüfgerät especially for medium caliber ammunition.

Insbesondere für die Entwicklung von neuartiger Munition ist es wichtig, dass Zündverhalten und den Zündvorgang dieser Munition zu kennen bzw. zu studieren. In der Regel wird für diese Aufgabe ein Beschussgerät verwendet und die Ergebnisse ausgewertet.In particular, for the development of novel ammunition, it is important to know or study the ignition behavior and the ignition process of this ammunition. As a rule, a firing device is used for this task and the results are evaluated.

Bekannt ist ein Munitionsprüfgerät aus der DE 14 28 695 A1 . Die Brauchbarkeit der Munition wird hierbei durch die Messung eines Höchstgasdruckes und die Ermittlung eines Trefferbildes in einer Versuchsreihe bestimmt. Vorgeschlagen wird, alle mit dem Waffenrohr beweglichen Anbauten wie auch den Gasdruckmessapparat so anzubringen, dass der gemeinsame Schwerpunkt in der Seelenachse des Rohres liegt.Is known a Munitionsprüfgerät from the DE 14 28 695 A1 , The usefulness of the ammunition is determined here by the measurement of a maximum gas pressure and the determination of a target image in a series of experiments. It is proposed to mount all attachments movable with the weapon barrel as well as the gas pressure gauge so that the common center of gravity lies in the axis of the tube.

Eine weitere Munitionsprüfvorrichtung für die Ermittlung von beim Anfeuern der Munition im Messlauf auftretenden innenballistischen bzw. rohrspezifischen Kenngrößen beschreibt die DE 31 32 085 C2 .A further ammunition testing device for determining inside ballistic or pipe-specific parameters occurring during the firing of the ammunition in the measuring run describes the DE 31 32 085 C2 ,

Mit der CH 629 891 A5 wird ein Munitionsprüfapparat mit einem piezoelektrischen Druckwandler offenbart.With the CH 629 891 A5 An ammunition testing apparatus with a piezoelectric pressure transducer is disclosed.

Ein Verfahren zum Sichtbarmachen eines abfeuerablaufes in einem Waffenrohr mittels Röntgenstrahlen ist aus der US 4 329 584 bekannt.A method for visualizing a firing process in a gun barrel by means of X-rays is known from US 4,329,584 known.

Nachteilig bei diesen Prüfgeräten ist, dass die Untersuchungen bzw. Auswertungen nur auf reinen Messergebnissen basieren.A disadvantage of these testers is that the examinations or evaluations are based only on pure measurement results.

Hier greift die Erfindung die Aufgabe auf, ein Munitionsprüfgerät aufzuzeigen, welches eine optimale Untersuchung ermöglicht.Here, the invention takes on the task to show an ammunition tester, which allows optimal investigation.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Eine Messanordnung wird in den Ansprüchen 9 und 10 beansprucht.The problem is solved by the features of claim 1. A measuring arrangement is claimed in claims 9 and 10.

Der Erfindung liegt die Idee zugrunde, um insbesondere den Zündungsvorgang einer Munition fotographisch untersuchen zu können, den Bereich, in welchem die Zündung erfolgt, aus einem Strahlen durchlässigen Material bzw. Werkstoff auszuführen. Bevorzugt kann es sich dabei um Röntgenstrahlen handeln.The invention is based on the idea, in particular to be able to photographically examine the firing process of an ammunition, the area in which the ignition takes place To carry out a radiation-permeable material or material. Preferably, these may be X-rays.

Der Röntgenstrahlen transparente und ein Patronenlager bzw. Ladungsruam im Messgerät bildende Bereich besteht dabei aus einem vorzugsweise zylindrischen Faserverbundkörper (Hybridgewebe), und ist in einem Metallgehäuse angebracht. Das im Messgerät verwendete Patronenlager ist aufgrund einer bevorzugten Wanddicke von maximal 25 - 30 mm für Röntgenstrahlen ausreichend durchlässig, um den Abbrandvorgang röntgentechnisch, z. B. mittels Röntgenkinematographie zu dokumentieren.The X-ray transparent and a cartridge storage or Ladungsruam forming in the meter range consists of a preferably cylindrical fiber composite body (Hygienwebe), and is mounted in a metal housing. Due to a preferred wall thickness of max. 25 - 30 mm, the cartridge chamber used in the measuring device is sufficiently permeable to X-rays in order to monitor the burn-up process using X-ray technology, eg. B. to document by X-ray cinematography.

Insbesondere bei der Prüfung von teleskopierter hülsenloser Munition treten hohe Drücke im Patronenlager auf. Der zylindrische Faserverbundkörper ist deshalb so gefertigt, dass dieser den hohen Drücken und Temperaturen, die infolge der Zündung und damit verbunden der Explosion eingeleitet werden, standhält, d.h., u. a. Beschussdrücke bis zu 4000 bar. Der Verbundkörper weist dazu eine entsprechende Anordnung verschiedener Schichten (Laminat) aus unterschiedlichen Faserverbundwerkstoffen auf.
Im axial abgestützten Zylinder treten des Weiteren in Umfangsrichtung große Zugspannungen auf, wobei insbesondere die inneren Schichten eine sehr große Druckbeanspruchung erfahren. Daher ist in einer bevorzugten Ausführung neben einem inneren Liner aus Polyamid wenigstens eine Rissstoppschicht im Laminat vorgesehen.Especially in the examination of telescoped caseless ammunition occur high pressures in the chamber. The cylindrical fiber composite body is therefore made to withstand the high pressures and temperatures introduced as a result of the ignition and, associated therewith, the explosion, ie, including impact pressures up to 4000 bar. The composite body has a corresponding arrangement of different layers (laminate) made of different fiber composites.
Furthermore, large tensile stresses occur in the axially supported cylinder in the circumferential direction, with the inner layers in particular experiencing a very great compressive stress. Therefore, in a preferred embodiment, in addition to an inner liner made of polyamide, at least one crack stop layer is provided in the laminate.

Es hat sich gezeigt, dass Kunstfaserverbundstoffe bis zu einer Laminatdicke von ca. 30 mm eine für die Untersuchung akzeptable Durchlässigkeit für die Röntgenstrahlen aber auch eine ausreichende Druckstabilität aufweisen. Als Faserverbundstoffe bieten sich AFK (Aramidfaserkunststoff), CFK (Kohlenstofffaserkunststoff) und / oder GFK (Glasfaserkunststoff) an. Dabei sollte das Laminat aus wenigstens zwei deutlich unterschiedlichen Faserorientierungen bestehen. Gewickelt werden dazu abwechselnd beispielsweise eine Aramidschicht, eine Glasfaserlage und darauf erneut eine Aramidschicht. Die Aramidfasern werden dabei beispielsweise jeweils in einem Winkel zwischen 25 bis 35 ° und die Glasfasern in einem Winkel von ca. 45° gewickelt.It has been shown that synthetic fiber composites up to a laminate thickness of about 30 mm have an X-ray permeability acceptable for the examination but also sufficient pressure stability. As fiber composites offer AFK (aramid fiber), CFRP (carbon fiber plastic) and / or GRP (fiberglass) to. The laminate should consist of at least two distinctly different fiber orientations. Alternately, for example, an aramid layer, a glass fiber layer and, again, an aramid layer are wound thereon. For example, the aramid fibers are each wound at an angle between 25 to 35 ° and the glass fibers at an angle of approximately 45 °.

Die Funktionsweise des Beschussgerätes bzw. des Munitionsprüfgerätes wird vorrangig durch den spezifischen Aufbau des Verbundkörpers, wie Faserart, Wickelwinkel und Auskleidung der Innenoberfläche mit Kunststoffen sowie dem Einbau des Körpers in das Beschussgerätgehäuse, beispielsweise innenzentriert mit Rohraufsatzkappen geprägt. In einigen Fällen sind Dichtungen, die einen Gasaustritt verhindern, wichtig. Diese Dichtungen können beispielsweise Kunststoffdichtungen sein, die eine spezifische Form aufweisen.The functioning of the firing device or the ammunition tester is primarily characterized by the specific structure of the composite body, such as fiber type, winding angle and lining of the inner surface with plastics and the installation of the body in the Beschussgerätgehäuse, for example, centered with pipe trim caps. In some cases, seals that prevent gas leakage are important. These seals may be, for example, plastic seals that have a specific shape.

Im Verbundkörper wird beispielsweise mit Hilfe der Röntgentechnik vorzugsweise oder auch vorrangig der Abbrand der Munition fotografiert. Dazu werden während des Schusses zu definierten Zeiten Bilder, hier Röntgenbilder, vom Innenleben des Patronenlagers bzw. Ladungsraums durch eine Messanordnung aufgenommen.In the composite body, the burn-up of the ammunition is preferably photographed, for example with the aid of X-ray technology or primarily. For this purpose, during the shot at defined times, images, in this case X-ray images, of the interior of the cartridge chamber or charge space are taken by a measuring arrangement.

In einer ersten Variante einer möglichen Messanordnung durchstrahlt eine Mehrfachanodenröhre das Beschussgerät mit Patronenlager, hinter dem sich ein Fluoreszenzschirm befindet. Dieser wandelt die Röntgenstrahlung in sichtbares Licht um, welches beispielsweise mit einer Hochgeschwindigkeitskamera mit einem vorgeschalteten Bildverstärker aufgenommen werden kann.In a first variant of a possible measuring arrangement, a multi-anode tube radiates through the firing device with cartridge chamber, behind which there is a fluorescent screen. This converts the X-radiation into visible light, which can be recorded, for example, with a high-speed camera with an upstream image intensifier.

Bei der bevorzugten weiteren Variante können auch mehrere (beispielsweise vier) Röntgenstrahlenquellen in die Messung eingebunden und zum Patronenlager in unterschiedlichen Winkeln ausgerichtet werden, so dass Messungen in verschiedenen Teilbereichen des Patronenlagers möglich sind. Hinter dem Patronenlager wird beispielsweise ein Röntgenfilm aufgestellt, wobei mittels Blenden sichergestellt wird, dass jede Strahlenquelle nur einen Bereich bzw. Streifen des Films belichtet. Für die Messung werden die Strahlenquellen zeitversetzt aktiviert.In the preferred further variant, several (for example four) X-ray sources can also be included in the measurement and aligned with the cartridge chamber at different angles, so that measurements in different subareas of the cartridge chamber are possible. For example, an X-ray film is set up behind the cartridge chamber, whereby it is ensured by means of diaphragms that each radiation source illuminates only one area or strip of the film. For the measurement, the radiation sources are activated with a time delay.

Als Innenliner 7 bietet sich insbesondere eine Ausführung ein Kunststoff, beispielsweise Polyamid an, auf den der Faserverbundstoff 8 bzw. die Lagen aufgewickelt werden. Die Herstellung bzw. Wicklung ist herkömmlich.The cartridge chamber 3 is a fiber-wound, X-ray transparent, cylindrical body and preferably centered in the firing device 1 or in the housing 2.

Die Strahlengänge X1-4 treten dabei durch das Patronenlager 3 eingangsseitig unter einem definierten Winkel ein und ausgangsseitig wieder aus und treffen auf die Detektoranordnung 12 auf. Mit Hilfe der dabei abgebildeten Röntgenbilder (nicht näher dargestellt) kann dann der Zündvorgang in seiner Gesamtheit bzw. das Abbrandverhalten im speziellen ausgewertet werden.For the measurement, the radiation sources 11 are activated one after the other at defined time intervals. In this case, the beam paths X 1-4 enter through the cartridge chamber 3 on the input side at a defined angle and exit again on the output side and impinge on the detector arrangement 12. With the help of the X-ray images shown here (not shown in detail), the ignition process in its entirety or the burning behavior can be evaluated in particular.
