Abstract

Currently, 9 mm x 19 mm calibre cartridges in the form of full-jacketed round-head bullets are used for small arms, especially for arms used by police. For safety reasons, efforts are being made to replace these bullets with a type of bullet that is prevented from passing straight through the target medium. Known deformable bullets from the prior art vary considerably in terms of the energy that they release in the target medium of density (1), especially in the human body. The invention therefore provides that the bullet (1) consists of a jacketless bullet body (2), that a cavity (5) extends centrally in relation to the longitudinal axis (15) of the bullet (1) in the tapered front part (6) of the bullet body (2), said cavity consisting of a cylindrical part (16) and at least one conical part (19) adjoining said cylindrical part; that a pusher (3) which forces the projectile open forms the bullet tip and that said pusher consists of a head (7) which seals the opening (4) of the cavity (5) and a shaft (8) which extends into the cavity (5).

FaustfeuerwaffenHandguns
Bei Faustfeuerwaffen, insbesondere für Waffen, die für den Polizeieinsatz vorgesehen sind, werden derzeit die Patronen des Kalibers 9 mm x 19 mm als Vollmantel-Rundkopfgeschosse verwendet. Aus sicherheitstechnischen Überlegungen heraus bestehen Bestrebungen, diese Geschosse durch einen gegen Durchschüsse durchs Zielmedium sichereren Geschoßtyp zu ersetzen. Bereits aus dem Stand der Technik bekannte Deformationsgeschosse variieren bei ihrer Energieabgabe im Zielmedium der Dichte 1 , insbesondere im menschlichen Körper, über eine große Bandbreite.In the case of handguns, in particular for weapons intended for police use, the 9 mm x 19 mm caliber cartridges are currently used as round, full-shell bullets. For safety reasons, efforts are being made to replace these projectiles with a type of projectile that is safer against bullets through the target medium. Deformation bullets already known from the prior art vary over a wide range in their energy delivery in the target medium of density 1, in particular in the human body.
Der Erfindung liegt die Aufgabe zugrunde, die Außen- und Zielballistik des Geschosses zu optimieren.The object of the invention is to optimize the outer and target ballistics of the projectile.
Die Lösung der Aufgabe erfolgt mit Hilfe der kennzeichenden Merkmale des ersten Anspruchs. Vorteilhafte Ausgestaltung der Erfindung werden in den Unteransprüchen beansprucht.The problem is solved with the aid of the characterizing features of the first claim. Advantageous embodiments of the invention are claimed in the subclaims.
Das erfindungsgemäße Deformationsgeschoß besteht aus einem mantellosen Metallkörper mit einem vorderen, sich zur Spitze des Geschosses hin verjüngenden Teil und einem hinteren, im wesentlichen zylindrischen Teil. Im vorderen, sich verjüngenden Teil des Geschosses erstreckt sich in Richtung seiner Längsachse ein Hohlraum, der sich aus einem zylindrischen und mindestens einen sich daran anschließenden konischen Teil sowie ein Sackloch zusammensetzt. Die Geschoßspitze wird durch einen sogenannten Aufbrech-Stößel gebildet, der die Öffnung des Geschosses zum Hohlraum verschließt. Der Aufbrech-Stößel besteht aus einem die Öffnung der Geschoßspitze verschließenden Kopf, an den sich ein in den engsten Teil des Hohlraums, das Sackloch, erstreckender Schaft anschließt.The deformation projectile according to the invention consists of a jacket-free metal body with a front part that tapers towards the top of the projectile and a rear, essentially cylindrical part. In the front, tapering part of the projectile, a cavity extends in the direction of its longitudinal axis, which cavity is composed of a cylindrical and at least one conical part adjoining it and a blind hole. The projectile tip is formed by a so-called break-open plunger, which closes the opening of the projectile to the cavity. The break-open plunger consists of a head which closes the opening of the projectile tip and which is followed by a shaft which extends into the narrowest part of the cavity, the blind hole.
Mit dem erfindungsgemäßen Geschoß wird eine gezielte Deformation erreicht. Der Aufbrech-Stößel, der mit seinem Kopf die Öffnung des Hohlraums im Geschoß verschließt, wird beim Auftreffen auf den Zielkörper in den Hohlraum gedrückt. Dabei wird der sich verjüngende Teil des Geschoßkörpers von der Öffnung des Hohlraums aus aufgepilzt. Das Geschoß wird zu einer pilzähnlichen Gestalt deformiert. Die Deformation des Geschoßkörpers stoppt dann, wenn die auf den Geschoßkörper einwirkende Energie zur Deformation nicht mehr ausreicht.A targeted deformation is achieved with the projectile according to the invention. The break-open plunger, with its head opening the cavity in the floor closes, is pressed into the cavity when it hits the target body. The tapered part of the projectile body is mushroomed from the opening of the cavity. The projectile is deformed into a mushroom-like shape. The deformation of the projectile body stops when the energy acting on the projectile body is no longer sufficient for the deformation.
Das Deformationsverhalten des Geschoßkörpers wird durch folgende Faktoren wesentlich beeinflußt: die Zusammensetzung des Werkstoffs und seine Eigenschaften und die Geometrie des Hohlraums und des Aufbrech-Stößels.The deformation behavior of the projectile body is significantly influenced by the following factors: the composition of the material and its properties and the geometry of the cavity and the tappet.
Nachstehend wird die erfindungsgemäße Werkstoffzusammensetzung des Geschoßkörpers angegeben:The material composition of the projectile body according to the invention is given below:
55 % - 100 % Kupfer (Cu), 0 % - 45 % Zink (Zn) und 0 % - 4 % Blei (Pb).55% - 100% copper (Cu), 0% - 45% zinc (Zn) and 0% - 4% lead (Pb).

Die Werkstoffzusammensetzung sowie die anschließende Wärmebehandlung führen zu einem optimalen Deformationsverhalten, das beimHeat treatment achieved ratio of yield strength to tensile strength cause the projectile to deform when it hits the target body without the fear of splitting. The material composition and the subsequent heat treatment lead to an optimal deformation behavior, which

Geschoßkörpers verhindert. Das Aufpilzen ohne Abreißen von Splittern führt zu einer definierten Energieabgabe und damit Abbremsung des Geschosses im Zielkörper.Projectile body prevented. The mushrooming without tearing off splinters leads to a defined release of energy and thus braking of the projectile in the target body.
Dadurch wird, abgesehen innerhalb eines extremen Nahbereichs, bei der Verwendung dieses Geschosses ein Durchschuß durch den Zielkörper wirkungsvoll vermieden.As a result, apart from within an extremely close range, a bullet through the target body is effectively avoided when using this projectile.
Der Geschoßkörper ist auf seiner Oberfläche verzinnt. Die Dicke der Zinnschicht liegt etwa zwischen 1 μm und 150 μm, vorzugsweise etwa zwischen 2 μm und 5 μm. Durch das Verzinnen wird eine Verbesserung der Gleiteigenschaften im Lauf erreicht und ein optimales Aufpilzen des Geschoßkörpers unterstützt.The projectile body is tinned on its surface. The thickness of the tin layer is approximately between 1 μm and 150 μm, preferably approximately between 2 μm and 5 μm. Tinning improves the sliding properties in the barrel and supports an optimal mushrooming of the projectile body.
Das Deformationsverhalten des Geschoßkörpers wird weiterhin durch seine optimale Formgebung bestimmt, hier insbesondere durch die Form des Hohlraums und. des ihn verschließenden Aufbrech-Stößels. Der die Öffnung zum Hohlraum des Geschoßkörpers verschließende Aufbrech-Stößel setzt sich zusammen aus einem Kopf und einem sich darin anschließenden Schaft. Der Schaft ist in der Regel zylindrisch und wird in der Sacklochbohrung im Geschoßkörper geführt. Der Schaft hat einen Durchmesser von etwa 2 mm und ist gegenüber dem Sacklochdurchmesser um so viel größer, daß ein Preßsitz erfolgt. Damit beim Eintreiben des Schaftes in das Sackloch die Luft im Sackloch entweichen kann, ist der Schaft einseitig angeflacht. Der Kopf des Aufbrech-Stößels ist in zwei Hälften aufgeteilt, von denen die dem Geschoßkörper zugewandte und die Öffnung verschließende Hälfte konisch geformt ist. Die aus dem Geschoß herausragende zweite Hälfte, die Spitze oder Kappe, hat im Schnittbild die Form einer Parabel. Dadurch wird die Geschoßspitze besonders strömungsgünstig. Weiterhin kann die Kappe des Aufbrech-Stößels zentrisch zur Längsachse des Geschoßkörpers eine Bohrung aufweisen. Durch die Bohrung wird die Krafteinwirkung und das Deformationsverhalten insbesondere in Weichzielen verstärkt. Diese Bohrung kann zylindrisch, konisch, kegelförmig oder gerundet sein. Sie hat eine Tiefe von etwa 0,5 mm bis 4 mm, vorzugsweise von etwa 1 mm bis 2 mm, und einen Durchmesser an der Öffnung von etwa 0,5 mm bis 4 mm, vorzugsweise von etwa 2 mm.The deformation behavior of the projectile body is further determined by its optimal shape, here in particular by the shape of the cavity and. the ram tappet closing it. The break-open plunger closing the opening to the cavity of the projectile body is composed of a head and a shaft adjoining it. The shaft is usually cylindrical and is guided in the blind hole in the projectile body. The shaft has a diameter of about 2 mm and is so much larger than the blind hole diameter that an interference fit takes place. The shaft is flattened on one side so that the air can escape in the blind hole when the shaft is driven into the blind hole. The head of the break-open plunger is divided into two halves, of which the half facing the projectile body and closing the opening is conically shaped. The second half protruding from the floor, the tip or cap, has the shape of a parabola in the sectional view. This makes the top of the floor particularly aerodynamic. Furthermore, the cap of the break-open plunger can have a bore centered on the longitudinal axis of the projectile body. The drilling increases the force and the deformation behavior, especially in soft targets. This bore can be cylindrical, conical, conical or rounded. It has a depth of approximately 0.5 mm to 4 mm, preferably approximately 1 mm to 2 mm, and a diameter at the opening of approximately 0.5 mm to 4 mm, preferably approximately 2 mm.
Die Öffnung in der Spitze des Geschoßkörpers hat eine zylindrische Form mit einem Durchmesser etwa zwischen 4 mm und 6 mm, vorzugsweise etwa zwischen 5 mm und 5,5 mm. Die Wandstärke in der Spitze des Geschoßkörpers wird dadurch so weit herabgesetzt, daß ein optimales Aufpilzen des Geschoßkörpers erfolgt.The opening in the tip of the projectile body has a cylindrical shape with a diameter of approximately between 4 mm and 6 mm, preferably approximately between 5 mm and 5.5 mm. The wall thickness in the tip of the projectile body is reduced so much that an optimal mushrooming of the projectile body takes place.

Hohlraums hat eine Länge von etwa 2 mm bis 7 mm, vorzugsweise von etwa 3 mm bis 5 mm. Daran schließt sich ein konischer Teil von etwa 1 mm bis 2 mm, vorzugsweise von etwa 1 ,5 mm an. Dieser konische Teil ist auf den vorhergehenden zylindrischen Teil in seiner Länge abgestimmt. Der Konuswinkel liegt etwa zwischen 50° und 70°, vorzugsweise bei etwa 60°. Diesem konischen Teil kann sich noch ein wesentlich kürzerer konischer Teil mit einem etwa doppelt so großen Konuswinkel anschließen, bevor die Öffnung in das Sackloch zur Führung des Schaftes des Aufbrech-Stößels übergeht.The cavity has a length of approximately 2 mm to 7 mm, preferably approximately 3 mm to 5 mm. This is followed by a conical part of approximately 1 mm to 2 mm, preferably from about 1.5 mm. This conical part is matched in length to the preceding cylindrical part. The cone angle is approximately between 50 ° and 70 °, preferably approximately 60 °. This conical part can be followed by a much shorter conical part with an approximately twice as large cone angle before the opening merges into the blind hole for guiding the shank of the break-open plunger.
Die zylindrische Bohrung ist mindestens um ein paar zehntel Millimeter länger als der Schaft des Aufbrech-Stößels und hat eine Länge von etwa 2 mm bis 7 mm, vorzugsweise von etwa 1 mm bis 3 mm, und ist auf die Länge des Schaftes des Aufbrech-Stößels abgestimmt.The cylindrical bore is at least a few tenths of a millimeter longer than the shank of the break-open ram and has a length of approximately 2 mm to 7 mm, preferably approximately 1 mm to 3 mm, and is the length of the shaft of the break-open ram Voted.
Der Aufbrech-Stößel besteht aus einem bleifreien Werkstoff. Es können beispielsweise Kunststoffe wie Polyethylen (PE) oder beispielsweise Metalle wie Zinn, Zink, Aluminium oder Kupfer verwendet werden. Vorteilhaft sind auch biologisch abbaubare Kunststoffe. Weiterhin trägt der geringe Bleianteil im Geschoßkörper dazu bei, eine toxische Kontamination des Gewebes weitestgehend zu vermeiden. Das Geschoß kann damit als schadstoffreduziert bezeichnet werden.The break-open ram is made of a lead-free material. For example, plastics such as polyethylene (PE) or, for example, metals such as tin, zinc, aluminum or copper can be used. Biodegradable plastics are also advantageous. Furthermore, the small amount of lead in the projectile body helps to largely avoid toxic contamination of the tissue. The floor can thus be described as reduced in pollutants.
Wenn der Aufbrech-Stößel aus Kunststoff besteht, ist in dem Kopf des Aufbrech- Stößels ein Metallpulver eingeschlossen, welches eine besonders gute Streuung von Röntgenstrahlen hervorruft, wie beispielsweise Eisen oder Wolfram oder der Werkstoff Barium-Sulfit (BaSO4). Dadurch ist es möglich, den Aufbrech-Stößel insbesondere dann im Gewebe des Zielkörpers wiederzufinden, wenn sich durch einen unglücklichen Umstand der Aufbrech-Stößel vom übrigen Geschoßkern getrennt hat.If the break-open plunger is made of plastic, a metal powder is enclosed in the head of the break-open plunger, which causes particularly good scattering of X-rays, such as iron or tungsten or the material barium sulfite (BaSO 4 ). This makes it possible to find the break-open plunger in the tissue of the target body in particular when the break-open plunger has separated from the rest of the projectile core due to an unfortunate circumstance.
Weiterhin wird durch die Form des Kopfes des Aufbrech-Stößels das Deformationsverhalten des aufprallenden Geschosses beeinflußt. Der konische Teil des Kopfes des Aufbrech-Stößels ist in die Öffnung zum Hohlraum des Geschoßkörpers eingeklemmt, die wie eine Fase geformt ist. In diese konische Fläche, die den gleichen Konuswinkel wie der Konuswinkel des Kopfes des Aufbrech-Stößels aufweist, bildet nur über wenige zehntel Millimeter Länge die Öffnung.Furthermore, the shape of the head of the break-open plunger influences the deformation behavior of the projectile impacting. The conical part of the head of the break-open plunger is clamped in the opening to the cavity of the projectile body, which is shaped like a chamfer. In this conical surface, the same cone angle as the cone angle of the head of the Has break-open plunger, forms the opening only a few tenths of a millimeter in length.
Trifft das Geschoß auf den Zielkörper auf, so wird durch den Aufprall der Kopf des Aufbrech-Stößels durch die Öffnung des Geschoßkörpers zunächst in den zylindrischen Teil des Hohlraums hineingedrückt. Dabei drückt der hintere konische Teil des Kopfes das Material der dünnen Wand des Geschoßkörpers nach außen, so daß dieses aufreißt und sich entgegen der Bewegungsrichtung des Geschoßkörpers nach hinten aufrollt und dadurch dem Geschoßkörpers eine pilzförmige Form verleiht. Trifft der konische Teil des Geschoßkörpers auf den sich verjüngenden konischen Teil des Hohlraums, wird das Eindringen des Kopfes des Aufbrech-Stößels abgestoppt. Der Konuswinkel des konischen Teils des Kopfes des Aufbrech-Stößels ist um wenige Winkelgrade geringer als der Konuswinkel des konischen Teils des Hohlraums des Geschoßkörpers, so daß er vollständig in diesen konischen Teil des Hohlraums eindringt und dort dann gestoppt wird. Die Geometrie des Geschoßkörpers sowie des Aufbrech-Stößels sind so aufeinander abgestimmt, insbesondere in Bezug auf die Geometrie des Hohlraums, daß beim Eindringen des Geschoßkörpers in den Zielkörper während des Aufpilzens der Geschoßkörper sich nicht in Splitter zerlegt.If the projectile strikes the target body, the impact of the head of the break-open plunger is initially pressed into the cylindrical part of the cavity through the opening of the projectile body. The rear conical part of the head presses the material of the thin wall of the projectile body outwards, so that it tears open and rolls up against the direction of movement of the projectile body and thereby gives the projectile body a mushroom-shaped shape. If the conical part of the projectile body meets the tapered conical part of the cavity, the penetration of the head of the break-open plunger is stopped. The cone angle of the conical part of the head of the break-open plunger is a few degrees lower than the cone angle of the conical part of the cavity of the projectile body, so that it penetrates completely into this conical part of the cavity and is then stopped there. The geometry of the projectile body and the break-open plunger are coordinated with one another, in particular with regard to the geometry of the cavity, that when the projectile body penetrates into the target body during the mushrooming, the projectile body does not break down into fragments.
Am Geschoßheck ist mittig zur Längsachse des Geschosses eine konische Vertiefung eingebracht. Die Tiefe beträgt etwa 0,5 mm bis 3 mm, vorzugsweise etwa 1 mm bis 2 mm. Der Konuswinkel liegt etwa zwischen 70° und 120°, vorzugsweise etwa bei 90°. Der Durchmesser richtet sich nach Konuswinkel und Tiefe. Die Vertiefung kann kegelförmig spitz zulaufen, es kann aber auch eine kreisförmige Bodenfläche vorgesehen sein, so daß der Durchmesser dieser Bodenfläche von etwa 0 mm bis 2 mm variieren kann, vorzugsweise liegt der Durchmesser bei etwa 1 mm. Die Vertiefung ist ebenfalls auf die Geometrie des Geschoßkörpers abgestimmt. Sie begünstigt das Strömungsverhalten der Treibgase und stabilisiert damit die Bewegung des Geschosses.At the rear of the projectile, a conical recess is made in the middle of the longitudinal axis of the projectile. The depth is approximately 0.5 mm to 3 mm, preferably approximately 1 mm to 2 mm. The cone angle is approximately between 70 ° and 120 °, preferably approximately 90 °. The diameter depends on the cone angle and depth. The depression can be tapered in a conical shape, but a circular base surface can also be provided, so that the diameter of this base surface can vary from approximately 0 mm to 2 mm, preferably the diameter is approximately 1 mm. The recess is also matched to the geometry of the projectile body. It favors the flow behavior of the propellant gases and thus stabilizes the movement of the projectile.
Anhand eines Ausführungsbeispiels wird die Erfindung näher erläutert. Das vorliegende Ausführungsbeispiel zeigt ein erfindungsgemäßes, mantelloses Deformationsgeschoß (1) für eine Patrone 9 mm x 19 mm für die Verwendung in Handfeuerwaffen, insbesondere in Polizeiwaffen, in stark vergrößertem Maßstab im Schnitt. Das Deformationsgeschoß (1) ist aus einem Geschoßkörper (2), der, wie hier nicht dargestellt, mit einer dünnen Zinnschicht von etwa 2 μm überzogen ist, und einem Aufbrech-Stößel (3) zusammengesetzt, der eine Öffnung (4) eines Hohlraumes (5) in dem sich verjüngenden Teil (6) des Geschoßkörpers (2) verschließt.The invention is explained in more detail using an exemplary embodiment. The present embodiment shows a sleeveless according to the invention Deformation bullet (1) for a 9 mm x 19 mm cartridge for use in small arms, in particular in police weapons, on a greatly enlarged scale on average. The deformation projectile (1) is composed of a projectile body (2), which, as not shown here, is coated with a thin tin layer of approximately 2 μm, and a break-open plunger (3), which has an opening (4) in a cavity ( 5) closes in the tapered part (6) of the projectile body (2).
Der Aufbrech-Stößel (3) besteht aus einem Kopf (7) und einem Schaft (8), der einen wesentlich geringeren Durchmesser aufweist als der Kopf (7). Der Kopf (7) setzt sich aus einer die Spitze des Geschosses (1) bildende Kappe (9) und einem die Öffnung (4) des Hohlraumes (5) verschließenden, hier zweifach abgestuften konischen Teils (10) zusammen. Die Kappe (9) hat aus aerodynamischen Gründen ein parabelförmiges Schnittprofil. Der Konuswinkel (11) des ersten konischen Teils (12) des Kopfs (7) beträgt im vorliegenden Ausführungsbeispiel 56°. Es ist der gleiche Winkel des einer Fase vergleichbaren Randes (13) der Öffnung (4), in die der konische Teil (12) des Kopfes (7) des Aufbrech-Stößels (3) eingepreßt ist. An den ersten konischen Teil (12) des Kopfes (7) schließt sich ein weiterer konischer Teil (14) mit einem etwa doppel so großen Konuswinkel an, der in den zylindrischen Schaft (8) übergeht. Der Schaft (8) hat insgesamt eine Länge von etwa 5 mm.The break-open plunger (3) consists of a head (7) and a shaft (8), which has a much smaller diameter than the head (7). The head (7) is composed of a cap (9) forming the tip of the projectile (1) and a conical part (10) which closes the opening (4) of the cavity (5) and is here stepped in two stages. The cap (9) has a parabolic cut profile for aerodynamic reasons. The cone angle (11) of the first conical part (12) of the head (7) is 56 ° in the present exemplary embodiment. It is the same angle of the edge (13) of the opening (4), which is comparable to a chamfer, into which the conical part (12) of the head (7) of the break-open plunger (3) is pressed. The first conical part (12) of the head (7) is followed by a further conical part (14) with an approximately twice as large cone angle, which merges into the cylindrical shaft (8). The shaft (8) has a total length of approximately 5 mm.
Der Hohlraum (5) im Geschoßkörper (2) ist symmetrisch zur Längsachse (15) des Geschoßkörpers (2) angeordnet. Der zylindrische Teil (16) des Hohlraumes (5) hat im vorliegenden Ausführungsbeispiel einen Durchmesser (17) von 5,5 mm. Dadurch wird die Wandstärke des sich verjüngenden Teils (6) des Geschoßkörpers (2) bis auf unter 1 mm herabgesetzt. Durch diese geringe Wandstärke wird das Deformationsverhalten des Geschoßkörpers wesentlich unterstützt. Die Länge (18) des zylindrischen Teils (16) des Hohlraums (5) beträgt im vorliegenden Ausführungsbeispiel 3 mm. Daran schließt sich ein erster konischer Teil (19) von 1 ,5 mm Länge (20) an. Der Konuswinkel (21) beträgt 60° und ist damit im vorliegenden Ausführungsbeispiel um 4° geringer als der Konuswinkel (11) des ersten konischen Teils (10) des Kopfes (7) des Aufbrech-Stößels (3). Dieser erste konische Teil (19) stoppt das weitere Eindringen des Aufbrech-Stößels (3) in den Geschoßkörper (2) beim Aufprall auf einen Zielkörper.The cavity (5) in the projectile body (2) is arranged symmetrically to the longitudinal axis (15) of the projectile body (2). The cylindrical part (16) of the cavity (5) has a diameter (17) of 5.5 mm in the present exemplary embodiment. As a result, the wall thickness of the tapered part (6) of the projectile body (2) is reduced to less than 1 mm. The deformation behavior of the projectile body is significantly supported by this small wall thickness. The length (18) of the cylindrical part (16) of the cavity (5) is 3 mm in the present exemplary embodiment. This is followed by a first conical part (19) of 1.5 mm in length (20). The cone angle (21) is 60 ° and is thus 4 ° smaller in the present exemplary embodiment than the cone angle (11) of the first conical part (10) of the head (7) of the break-open tappet (3). This first conical part (19) stops further penetration of the break-open plunger (3) into the projectile body (2) upon impact with a target body.
An den ersten konischen Teil (19) schließt sich ein zweiter konischer Teil (22) von wenigen zehntein Millimetern Länge an. Sein Konuswinkel (23) ist hier mit 120° doppelt so groß wie der Konuswinkel (21) des ersten konischen Teils (19). Der zweite konische Teil (22) leitet mit einer Fase (24) zum leichteren Einführen des Schaftes (8) in das Sackloch (25) über. Das Sackloch (25) dient der Führung des Schaftes (8) und ist nur wenige zehntel Millimeter länger als dieser. Der Durchmesser (26) des Sackloches (25) beträgt 1 ,9 mm und ist um etwa 0,1 mm geringer als der Durchmesser (33) des Schaftes (8), so daß dieser durch einen Klemmsitz in dem Sackloch (25) gehalten wird. Mit (35) ist eine Abflachung des Schaftes (8) bezeichnet, die beim Eintreiben des Schaftes in das Sackloch (25) das Entweichen der Luft ermöglicht.The first conical part (19) is followed by a second conical part (22) of a few tenths of a millimeter in length. At 120 °, its cone angle (23) is twice as large as the cone angle (21) of the first conical part (19). The second conical part (22) leads with a chamfer (24) for easier insertion of the shaft (8) into the blind hole (25). The blind hole (25) serves to guide the shaft (8) and is only a few tenths of a millimeter longer than this. The diameter (26) of the blind hole (25) is 1.9 mm and is approximately 0.1 mm smaller than the diameter (33) of the shaft (8), so that it is held in the blind hole (25) by a clamp fit , (35) denotes a flattening of the shaft (8), which allows the air to escape when the shaft is driven into the blind hole (25).
Beim Auftreffen des Deformationsgeschosses (1) auf den Zielkörper wird zunächst der Kopf (7) des Aufbrech-Stößels (3) in den Hohlraum (5) hineingedrückt. Der erste konische Teil (12) des Kopfes (7) drückt dabei den Werkstoff der Wand des zylindrischen Teils (16) des Hohlraums (5) nach außen, so daß dieser sich beim Eindringen in den Zielkörper, ohne Abzureißen und dadurch ohne Splitterbildung, entgegengesetzt der Eindringrichtung zum Geschoßende (27) hin aufpilzt. Der Aufbrech-Stößel (3) wird durch seinen Schaft (8) bei der Rückwärtsbewegung in dem Sackloch (25) geführt. Dadurch erfolgt eine gleichmäßige Aufpilzung des Geschoßkörpers (2). Die Bewegung des Aufbrech-Stößels (3) wird dann gestoppt, wenn der erste konische Teil (12) des Aufbrech-Stößels (3) auf die Wand des ersten konischen Teils (19) des Hohlraums (5) auftritt.When the deformation bullet (1) strikes the target body, the head (7) of the break-open plunger (3) is first pressed into the cavity (5). The first conical part (12) of the head (7) presses the material of the wall of the cylindrical part (16) of the cavity (5) outwards, so that it penetrates into the target body without tearing and thus without splintering the direction of penetration towards the end of the floor (27). The break-open plunger (3) is guided through its shaft (8) during the backward movement in the blind hole (25). This causes the bullet body (2) to mushroom evenly. The movement of the break-open plunger (3) is stopped when the first conical part (12) of the break-open plunger (3) strikes the wall of the first conical part (19) of the cavity (5).
Am Geschoßheck (27) befindet sich zentrisch zur Längsachse (15) des Geschoßkörpers (2) eine Vertiefung (28). Sie ist konisch, wobei der Konuswinkel (29) 90° beträgt. Am Grund der Vertiefung befindet sich eine kreisförmige Fläche (30) mit einem Durchmesser (31) von 1 mm. Die Tiefe (32) der Vertiefung beträgt im vorliegenden Ausführungsbeispiel etwa 2 mm, ihr Durchmesser (34) etwa 5 mm. Diese Vertiefung dehnt insbesondere beim Abschuß dazu, das Abströmen der Treibgase zu beeinflussen und die Bewegung des Deformationsgeschosses (1) zu stabilisieren.At the rear of the projectile (27) there is a depression (28) centered on the longitudinal axis (15) of the projectile body (2). It is conical, the cone angle (29) being 90 °. At the bottom of the depression there is a circular surface (30) with a diameter (31) of 1 mm. The depth (32) of the depression in the present exemplary embodiment is approximately 2 mm, its diameter (34) approximately 5 mm. This depression expands, especially when firing, the outflow of the Influence propellant gases and stabilize the movement of the deformation floor (1).
Weiterhin weist die Kappe (9) des Aufbrech-Stößels (3) zentrisch zur Längsachse (15) des Geschoßkörpers (2) eine zylindrische Bohrung (36) auf. Sie hat beim vorliegenden Ausführungsbeispiel eine Tiefe (37) von 1 ,5 mm und einen Durchmesser (38) von 2 mm. Durch die Bohrung wird die Krafteinwirkung und das Deformationsverhalten insbesondere in Weichzielen verstärkt. Furthermore, the cap (9) of the break-open plunger (3) has a cylindrical bore (36) centrally to the longitudinal axis (15) of the projectile body (2). In the present exemplary embodiment, it has a depth (37) of 1.5 mm and a diameter (38) of 2 mm. The drilling increases the force and the deformation behavior, especially in soft targets.
