Abstract

Currently, 9 mmx19 mm caliber 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 ).

Description

Die Erfindung betrifft ein Deformationsgeschoß entsprechend dem Oberbegriff des ersten Anspruchs.The invention relates to a deformation floor according to the preamble of first claim.

Aus der WO 01/02791 A2 ist ein Deformationsgeschoß bekannt, das insbesondere für Jagdzwecke konzipiert ist. Im vorderen, sich verjüngenden Teil des Geschosses erstreckt sich in seiner Längsachse eine Höhle, deren Querschnitt sich von der Spitze ausgehend mehrfach stufenweise verengt. Mit diesem Geschoß soll, in Abhängigkeit von der Auftreffgeschwindigkeit, eine gezielte, auf das Wild abgestimmte Deformation des Geschosses erreicht werden.A deformation floor is known from WO 01/02791 A2, which in particular is designed for hunting purposes. In the front, tapered part of the floor extends in its longitudinal axis a cave, the cross section of which extends from the top starting from narrowed several times. With this projectile, depending on the impact speed, a targeted, matched to the game Deformation of the projectile can be achieved.

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.For handguns, especially for weapons used by the police are intended, the cartridges of caliber 9 mm x 19 mm are currently Solid shell round head bullets used. For security reasons Considerations have been made to try to use these projectiles against one another To replace bullets through the target medium of a safer bullet type. Already out Deformation bullets known in the prior art vary in their Release of energy in the target medium of density 1, in particular in the human body, over a wide range.

Der Erfindung liegt die Aufgabe zugrunde, die Außen- und Zielballistik eines solchen Geschosses zu optimieren.The invention has for its object the external and target ballistics of such Optimize storey.

Die Lösung der Aufgabe erfolgt mit Hilfe der kennzeichnenden Merkmale des ersten Anspruchs. Vorteilhafte Ausgestaltung der Erfindung werden in den Unteransprüchen beansprucht.The problem is solved with the help of the characteristic features of the first Claim. Advantageous embodiments of the invention are set out in the subclaims claimed.

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 floor according to the invention consists of a jacket Metal body with a front that tapers towards the top of the projectile Part and a rear, essentially cylindrical part. In the front, yourself tapering part of the projectile extends in the direction of its longitudinal axis Cavity consisting of a cylindrical and at least one attached to it adjoining conical part and a blind hole. The Projectile tip is formed by a so-called ram tappet, which The opening of the projectile closes to the cavity. The break-open ram is there from a head which closes the opening of the top of the floor, to which an in connects the narrowest part of the cavity, the blind hole, extending shaft.

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 ausreichtA 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. there the tapered part of the projectile body becomes from the opening of the cavity from mushroomed. The projectile is deformed into a mushroom-like shape. The Deformation of the projectile body stops when it hits the projectile body acting energy is no longer sufficient for 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 determined by the following factors significantly influenced: 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:

  • 55 % -100 % Kupfer (Cu),
  • 0 % - 45 % Zink (Zn) und
  • 0 % - 4 % Blei (Pb).
    • The material composition of the projectile body according to the invention is given below:
  • 55% -100% copper (Cu),
  • 0% - 45% zinc (Zn) and
  • 0% - 4% lead (Pb).

    • Durch eine Glühbehandlung mit anschließendem Tempern wird eine Zugfestigkeit Rm von 250 N/mm2 bis 450 N/mn2 und eine Streckgrenze von Rp0,2 von 150 N/mm2 bis 250 N/mm2 erreicht. Die Werkstoffzusammensetzung sowie das durch die Wärmebehandlung erreichte Verhältnis von Streckgrenze zu Zugfestigkeit bewirken beim Auftreffen auf den Zielkörper eine Deformation des Geschosses ohne das befürchtete Aufsplittem. Die Werkstoffzusammensetzung sowie die anschließende Wärmebehandlung führen zu einem optimalen Deformationsverhalten, das beim Eindringen in den Zielkörper ein Abreißen von Splittern beim Aufpilzen des Geschoßkörpers verhindert. Das Aufpilzen ohne Abreißen von Splittern führt zu einer definierten Energieabgabe und damit Abbremsung des Geschosses im Zielkörper. Dadurch wird, abgesehen innerhalb eines extremen Nahbereichs, bei der Verwendung dieses Geschosses ein Durchschuß durch den Zielkörper wirkungsvoll vermieden.An annealing treatment with subsequent tempering achieves a tensile strength R m of 250 N / mm 2 to 450 N / mn 2 and a yield strength of R p0.2 of 150 N / mm 2 to 250 N / mm 2 . The material composition and the ratio of yield strength to tensile strength achieved by the heat treatment 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 optimal deformation behavior, which prevents splinters from tearing off when the projectile body is mushroomed when penetrating into the target body. The mushrooming without tearing off splinters leads to a defined release of energy and thus braking of the projectile in the target body. 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. 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.

    Durch das Verzinnen wird eine Verbesserung der Gleiteigenschaften im Lauf erreicht und ein optimales Aufpilzen des Geschoßkörpers unterstützt.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 continues to be due to its optimal Shape determined, here in particular by the shape of the cavity and the ram tappet closing it. The opening to the cavity of the The ram tappet, which closes the projectile body, is composed of one Head and an adjoining shaft. 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 opposite Blind hole diameter so much larger that an interference fit takes place. With that at Driving the shaft into the blind hole allows the air in the blind hole to escape the shaft flattened on one side. The head of the break-open plunger is in two halves divided, of which the one facing the projectile body and the opening closing half is conical. The protruding from the floor the second half, 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 centered on the longitudinal axis of the projectile body Have hole. Through the hole, the force and the Deformation behavior especially in soft targets intensified. This hole can be cylindrical, conical, conical or rounded. It has a depth of approximately 0.5 mm to 4 mm, preferably from about 1 mm to 2 mm, and a diameter the opening of about 0.5 mm to 4 mm, preferably of about 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 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 becomes so wide reduced that an optimal mushrooming of the projectile body takes place.

    Ein weiterer Einflußfaktor auf das optimale Aufpilzen des Geschoßkörpers ist die Tiefe, also die Länge des Hohlraums und seine Form. Der zylindrische Teil des 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.Another factor influencing the optimal expansion of the projectile body is Depth, i.e. the length of the cavity and its shape. The cylindrical part of the The cavity has a length of approximately 2 mm to 7 mm, preferably approximately 3 mm up to 5 mm. This is followed by a conical part of about 1 mm to 2 mm, preferably from about 1.5 mm. This conical part is on the previous one cylindrical part matched in length. The cone angle is approximately between 50 ° and 70 °, preferably at about 60 °. This conical part can still be much shorter conical part with a cone angle that is about twice as large connect before opening in the blind hole to guide the shaft of the Break-open ram passes.

    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 that Shaft of the break-open ram and has a length of about 2 mm to 7 mm, preferably from about 1 mm to 3 mm, and is to the length of the shaft of the Broken ram tuned.

    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. It can for example plastics such as polyethylene (PE) or for example metals such as Tin, zinc, aluminum or copper can be used. Biological are also advantageous degradable plastics. The small amount of lead in the projectile body also contributes to this to avoid toxic contamination of the tissue as far as possible. The Projectile 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 a 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 again, in particular in the tissue of the target body, 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 ram tappet Deformation behavior of the impacting projectile is affected. The conical part the head of the break-open plunger is in the opening to the cavity of the Pinched body, which is shaped like a bevel. In this conical Area that has the same cone angle as the cone angle of the head of the Has break-open ram, forms only over a few tenths of a millimeter in length Opening.

    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 hits the target body, the impact of the head of the Break-open ram through the opening of the projectile body first in the cylindrical part of the cavity pressed. The rear conical presses Part of the head the material of the thin wall of the projectile body to the outside, so that this tears open and against the direction of movement of the projectile body rolls backwards and thereby gives the projectile body a mushroom shape. The conical part of the projectile body meets the tapered conical part Part of the cavity is the penetration of the head of the ram stopped. The cone angle of the tapered part of the head of the ram is a few degrees lower than the cone angle of the conical part of the Cavity of the projectile body so that it completely in this conical part of the Cavity penetrates and is then stopped there. The geometry of the The projectile body and the ram tappet are coordinated so especially in relation to the geometry of the cavity that when the Projectile body in the target body during the expansion of the projectile body itself not broken 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 there is a conical center to the longitudinal axis of the projectile Deepening introduced. The depth is about 0.5 mm to 3 mm, preferably about 1 mm to 2 mm. The cone angle is approximately between 70 ° and 120 °, preferably around 90 °. The diameter depends on the cone angle and depth. The The recess can be tapered, but it can also be a circular one Bottom surface can be provided so that the diameter of this bottom surface of about 0 mm to 2 mm can vary, preferably the diameter is about 1 mm. The recess is also matched to the geometry of the projectile body. she 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 The present exemplary embodiment shows an inventive, sleeveless Deformation bullet (1) for a 9 mm x 19 mm cartridge for use in Small arms, especially in police weapons, on a greatly enlarged scale in Cut. The deformation floor (1) consists of a floor body (2) which, as here not shown, is coated with a thin layer of tin of about 2 microns, and a ram tappet (3) composed of an opening (4) of a Cavity (5) in the tapered part (6) of the projectile body (2) closes.

    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 ram (3) consists of a head (7) and a shaft (8), one has a much smaller diameter than the head (7). The head (7) sits down of a cap (9) forming the tip of the projectile (1) and an opening (4) of the cavity (5) closing, here two-step conical part (10) together. The cap (9) has a for aerodynamic reasons parabolic section profile. The cone angle (11) of the first conical part (12) the head (7) is 56 ° in the present exemplary embodiment. It is the same Angle of the bevel edge (13) of the opening (4) into which the conical part (12) of the head (7) of the break-open plunger (3) is pressed. To the The first conical part (12) of the head (7) closes another conical part (14) with an approximately twice as large cone angle, which in the cylindrical Shaft (8) merges. 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 Deförmationsverhalten 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 symmetrical to the longitudinal axis (15) of the Projectile body (2) arranged. The cylindrical part (16) of the cavity (5) has present embodiment a diameter (17) of 5.5 mm. Thereby the wall thickness of the tapered part (6) of the projectile body (2) up to , reduced below 1 mm. Due to this small wall thickness Deflection behavior of the projectile body is significantly supported. The length (18) of the cylindrical part (16) of the cavity (5) is in the present Embodiment 3 mm. This is followed by a first conical part (19) of 1.5 mm length (20). The cone angle (21) is 60 ° and is therefore present Embodiment 4 ° smaller than the cone angle (11) of the first conical Part (10) of the head (7) of the break-open plunger (3). This first conical part (19) stops the ram tappet (3) from penetrating further into the projectile body (2) when hitting a target body.

    An den ersten konischen Teil (19) schließt sich ein zweiter konischer Teil (22) von wenigen zehnteln 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. Its cone angle (23) is 120 ° here twice the cone angle (21) of the first conical part (19). The second conical part (22) guides 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 about 0.1 mm less than that Diameter (33) of the shaft (8), so that this by a clamp in the Blind hole (25) is held. With (35) is a flattening of the shaft (8) referred to, the escape when driving the shaft into the blind hole (25) the air.

    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) hits the target body, the first step is the head (7) of the break-open plunger (3) is 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) to the outside, so that this at Penetration into the target body without tearing and thus without splintering, mushrooms against the direction of penetration towards the end of the floor (27). The Break-open plunger (3) is through its shaft (8) in the backward movement in the Blind hole (25) performed. This causes an even mushrooming of the Projectile body (2). The movement of the break-open ram (3) is then stopped, when the first conical part (12) of the break-open plunger (3) on the wall of the first conical part (19) of the cavity (5) occurs.

    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 tail end (27) is centered on the longitudinal axis (15) of the Projectile body (2) has a recess (28). It is conical, the cone angle (29) Is 90 °. At the bottom of the depression there is a circular surface (30) a diameter (31) of 1 mm. The depth (32) of the depression is present embodiment about 2 mm, its diameter (34) about 5 mm. This deepening expands, especially when firing, the outflow of the Influence propellant gases and the movement of the deformation floor (1) too stabilize.

    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 tappet (3) is centered on the longitudinal axis (15) of the projectile body (2) has a cylindrical bore (36). She has with present exemplary embodiment a depth (37) of 1.5 mm and a Diameter (38) of 2 mm. Through the hole, the force and the Deformation behavior especially in soft targets intensified.
