Abstract

A cartridge projectile (1) is fired by a medium-caliber handgun (30) and, upon impacting a target, acts as a kinetic energy projectile and bursts at its soft front projectile part (10) whereby releasing and spraying an active substance (17) stored inside the projectile body (9, 10). The necessary aiming accuracy is achieved by a pulse body (4), which contains a propellant charge (6) and by a gyroscopic stabilization in the rifling (31) of the firearm (30). The projectile is particularly suited for being specifically used with non-lethal active substances, particularly against individual rioters and aggressive demonstrators. .

Description

Berstgeschoss Berstgeschoss
Die vorliegende Erfindung bezieht sich auf eine Patrone nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a cartridge according to the preamble of claim 1.
Im Zusammenhang mit Demonstrationen, Sachbeschädigungen und Überfällen ist der Einsatz der Mittel durch die Ordnungs¬ oder Interventionskräfte situativ und angemessen zu wählen. Nach diesem Grundsatz wurden beispielsweise Hohlkörper wie Gummibälle, die mit Farbstoffen und/oder Tränen verursa- chenden Flüssigkeiten gefüllt sind aus Leuchtpistolen und dergleichen auf aggressive Demonstranten abgefeuert.In the context of demonstrations, property damage and assaults, the use of funds by the regulatory or intervention forces should be situational and appropriate. According to this principle, for example, hollow bodies, such as rubber balls, which are filled with dyes and / or tears-causing liquids, are fired from flare pistols and the like onto aggressive demonstrators.
Die Zielgenauigkeit und Reichweite solcher Geschosse hat sich aber als ungenügend erwiesen, so dass diese meist nicht über das Versuchsstadium hinaus zur Anwendung gelang- ten. Dementsprechend werden von den Ordnungskräften heute immer noch Wasserwerfer und Gummiknüppel eingesetzt, was der Mobilität und dem Reaktionsvermögen von meist trainier¬ ten und gut instruierten Randalierern nicht angepasst ist.However, the accuracy and range of such projectiles has proved to be insufficient, so that they usually do not beyond the experimental stage out came to the application. Accordingly, the police still today water cannons and rubber truncheons are used, which the mobility and responsiveness of most trainier ¬ and well-trained rioters is not adjusted.
Es ist daher Aufgabe der Erfindung ein patroniertes Ge- schoss zu schaffen, das von an sich bekannten und bereits bei den Ordnungs- und/oder Interventionskräften vorhandenen Waffen abfeuerbar ist. Die Wirkung des Geschosses soll ei¬ nerseits auf der Impulsabgabe im Ziel (Schlagwirkung) und anderseits auf einer nachhaltigen, Stoff-Einwirkung (che- misch/pysikalischen Reaktion) beruhen, welche den Angreifer an einer Gegenwehr hindert, eine Festnahme ermöglicht oder zur Flucht zwingt. Die Zielgenauigkeit muss derart hoch sein, dass mit einem Erstschuss auch in einer Entfernung von 20 m ein anvisiertes Körperteil an einem Menschen si- eher getroffen wird. Das zu Einsatz gelangende Geschoss darf an Personen zu keinen grosseren Hautverletzungen oder gar Knochenbrüchen führen. Ebenfalls soll das Geschoss ge¬ gen grossere Tiere erfolgreich einsetzbar sein.It is therefore an object of the invention to provide a cartridgeed projectile which can be fired by weapons which are known per se and already present in the order and / or intervention forces. On the one hand, the effect of the projectile should be based on the impulse delivery in the target (impact effect) and, on the other hand, on a sustained substance (chemical / physical reaction), which prevents the attacker from countering, makes it possible to arrest him or forces him to flee , The aiming accuracy must be so high that with a first shot even at a distance of 20 m an aimed body part on a person rather gets hit. The projectile used may not lead to persons any major skin injuries or even bone fractures. Likewise, the projectile should be able to be used successfully against larger animals.
Diese Aufgabe ist durch die Merkmale des Anspruchs 1 ge¬ löst.This object is achieved by the features of claim 1 ge.
Der im Patentanspruch genannte Impulskörper erfährt durch seine zentral eingelagerte Treibladung eine hohe koaxiale Beschleunigung und überträgt diese als Abschussenergie achsparallel auf das mit ihm in Kontakt stehende Geschoss. Im taktischen Einsatz ist die Auftreffenergiedichte (Flä¬ chendichte) im Ziel derart hoch, dass eine von einem 40 mm Geschoss unvorbereitet getroffene Person, auch in einem Ab¬ stand zum Schützen von über 20 m Schmerzen erleidet und stark irritiert ist. Der beim Aufprall des Geschosses aus¬ tretende Wirkstoff, beispielsweise verdünntes Capsaicin setzt die Person kurzzeitig ausser Gefecht, so dass eine Gegenwehr meist nicht mehr erfolgen kann.The impulse body mentioned in the claim undergoes a high coaxial acceleration due to its centrally stored propellant charge and transmits this as a firing energy parallel to the axis to the projectile in contact with it. In tactical use, the impact energy density (surface density) in the target is so high that a person who has been hit unprepared by a 40 mm bullet suffers pain and is greatly irritated even at a distance of more than 20 m. The agent which emerges on impact of the projectile, for example diluted capsaicin, puts the person out of action for a short time, so that resistance can usually no longer be provided.
Der Erfindungsgenstand lässt sich in weiten Grenzen an vor- handene Waffensystem anpassen; er kann insbesondere über Aufsatz- oder Zusatzrohre an Ordonnanzgewehren und Granat¬ pistolen sicher abgefeuert werden.The subject invention can be adapted within wide limits to existing weapon systems; in particular, it can be safely fired by means of top-mounted or additional tubes of ordnance guns and grenade pistols.
In nachfolgenden abhängigen Ansprüchen sind Weiterbildungen des Erfindungsgegenstands beschrieben.In subsequent dependent claims further developments of the subject invention are described.
Durch Führungsmittel wie Führungsbänder lässt sich in ent¬ sprechenden Waffen am Geschoss ein Drall erzeugen, der die¬ sem eine Stabilisierung und in der Folge eine erhöhte Ziel¬ genauigkeit verschafft, Anspruch 2. Durch den Einsatz eines Impulskörpers nach Anspruch 3 und damit durch eine mittelbare Übertragung der Energie der Treibladung erhöht sich die Zielgenaugikeit beträchtlich.Guide means, such as guide strips, can be used to generate a twist on the projectile in corresponding weapons, which gives the latter stabilization and, as a consequence, increased target accuracy, claim 2. By using a pulse body according to claim 3 and thus by an indirect transfer of the energy of the propellant charge Zielgenaugikeit increases considerably.
Das in Anspruch 4 genannte Verhältnis der Treibladung von Durchmesser zu Länge ergibt nochmals eine Steigerung der endballistischen Leistung und der Zielgenauigkeit.- Dies insbesondere im Vergleich mit Ladungen deren Durchmesser grösser ist als deren Länge.The ratio of the propellant charge from diameter to length mentioned in claim 4 again results in an increase in the end ballistic performance and the accuracy of the target. This is particularly the case in comparison with charges whose diameter is greater than their length.
Durch die Kontaktierung des Impulskörpers mit einem Teil des Geschosses, einem sogenannten Treiberstutzen entsteht eine ideale Impulsübergabe; Anspruch 5.By contacting the impulse body with a part of the projectile, a so-called driver socket, an ideal momentum transfer results; Claim 5.
Radiale Seitenführungen am Heckteil des Geschosses, An¬ spruch 6, die in der Patrone anliegen, gewährleisten einen zur Mittelachse des Rohres symmetrisch verlaufenden Ab- schuss.Radial side guides on the rear part of the projectile, An¬ claim 6, which abut in the cartridge, ensure a symmetrical to the central axis of the tube shot.
Mittels einer elastischen Dichtung lassen sich das Heckteil und das Frontteil des Geschosses gasdicht verbinden; vgl. Anspruch 7.By means of an elastic seal, the rear part and the front part of the projectile can be connected in a gastight manner; see. Claim 7.
Die in Anspruch 8 genannten Sollbruchstellen verbessern das Berstverhalten des Frontteils des Geschosses.The predetermined breaking points mentioned in claim 8 improve the bursting behavior of the front part of the projectile.
Eine Kugelkalotte 15 mit einem äusseren Radius von wenig¬ stens 150 mm verhindert Augenverletzungen und oder Punktbe¬ lastungen im Ziel, die zu Verletzungen der Haut oder von Organen führen könnten, Anspruch 9.A spherical cap 15 with an outer radius of at least 150 mm prevents eye injuries and / or point loads in the target, which could lead to injuries to the skin or organs, claim 9.
Eine weitere Verbesserung erfährt das Geschoss durch Aus¬ nehmungen im Bereich der Kugelkalotte nach Anspruch 10 in seiner Durchbiegefähigkeit am Ziel, was zusätzlich auch dessen Berstverhalten verbessert.A further improvement is experienced by the projectile by recesses in the area of the spherical cap according to claim 10 in FIG its bending ability at the target, which also improves its bursting behavior.
Eine Ausführung des Frontteils des Geschosses in EPDM (Äthylen-Propylen-Dien-Kautschuk) ergibt ein beim Auftref- fen auch auf weiche Ziele ein elastisches Verhalten. Damit reduziert sich die am Ziel belegte Energiedichte (Energie pro Flächeneinheit) , wobei gleichzeitig die Knickbelastung des Materials vergrössert wird, so dass dessen gewünschtes Bersten sicher erfolgt; Anspruch 11.An embodiment of the front part of the projectile in EPDM (ethylene-propylene-diene rubber) results in an elastic behavior even when encountering soft targets. This reduces the energy density (energy per unit area) occupied at the target, at the same time increasing the buckling load of the material so that its desired bursting occurs safely; Claim 11.
Durch das Einbringen nicht letaler Wirk- und/oder Markier¬ stoffe in das Geschoss kann dessen Einsatz situativ opti¬ miert werden, d.h. durch die Bereitstellung von Geschossen mit unterschiedlicher Füllung lässt sich die Wirkung im Ziel optimal planen und realisieren. Siehe Anspruch 12.By introducing non-lethal active substances and / or markers into the projectile, its use can be optimized in a situational manner, i. By providing projectiles with different fillings, the effect on the target can be optimally planned and implemented. See claim 12.
Nachfolgend werden an Hand von Zeichnungen Ausführungsbei¬ spiele der Erfindung erläutert.Hereinafter, embodiments of the invention will be explained with reference to drawings.

Fig. 6 das vollständige Geschoss beim Aufprall im Ziel mit seiner Streu- und oder Sprühwirkung.Fig. 6 shows the entire projectile upon impact with the target with its scattering and or spraying.
In Figur 1 ist eine patroniertes Geschoss mit 1 bezeichnet. Es ist in ein vereinfacht dargestelltes Rohr 30 (Lauf) ei¬ ner konventionellen Waffe eingesetzt. Ein nicht eingezeich¬ neter Zündstift schlägt auf ein Zündelement 3 im Boden ei¬ ner Patronenhülse 2, die einen Zündkanal 3' aufweist, wel- eher mit einer zentral in einem Impulskörper 4 angeordneten Treibladung 6 in Wirkverbindung steht.In Figure 1, a cartridgeed projectile is designated 1. It is inserted into a tube 30 (barrel) of a conventional weapon, shown in simplified form. A firing pin which is not marked strikes an ignition element 3 in the bottom of a cartridge casing 2, which has an ignition channel 3 ', which is in operative connection with a propellant charge 6 arranged centrally in a pulse body 4.
Der Impulskörper 4 ist kolbenartig ausgebildet und besteht aus einem handelsüblichen Polyacetal-Kunststoff (Polyoxy- methylen = POM) . Die Treibladung 6 ist in einem zylindri- sehen Hohlraum 5 eingefüllt, dessen Länge 1 grösser ist als der Durchmesser d. Eine brennbare mechanische Abdeckung 7 (Folie) wirkt als mechanische und als Feuchtigkeitssperre sowie gleichzeitig als Zündverteiler auf der Stirnfläche der Treibladung. Der Impulskörper 4 besitzt, in Abschuss- richtung A betrachtet, in seiner Stirnfläche Aussparungen 8, die der Gewichtsoptimierung, bzw. zur Gewichtsreduktion dienen. Auf der gleichen Stirnfläche liegt ein Treiber¬ stutzen 12 auf, welcher Bestandteil des Heckteils 9 eines Geschosses ist. Ein Frontteil 10 verschliesst das Geschoss und begrenzt einen Hohlraum, der in Abschussrichtung A ge¬ sehen, mit einem Wirkstoff 17 gefüllt ist. Ein Verschluss¬ zapfen 14 bildet die heckseitige Sperre in diesem Hohlraum und dient dem Gewichtsausgleich, d.h. durch dessen Dimen¬ sionierung und Materialwahl lässt sich der Massenschwer- punkt des Geschosses einstellen. Einstückig am Heckteil 9 ist eine dünnwandige Seitenführung 11 vorhanden, die formschlüssig am inneren Zylindermantel 2a anliegt und nach der Impulsübertragung auf die Teile 9 und 10 deren achsparallele Führung übernimmt. Der einge- schlossene Hohlraum 13 sowie der Luftraum IIa werden bei der Impulsübertragung etwas komprimiert, da der Treiber¬ stutzen 12 nachgiebig ist; was den Formschluss der Seiten¬ führung 11 erhöht.The pulse body 4 is formed like a piston and consists of a commercially available polyacetal plastic (polyoxymethylene = POM). The propellant charge 6 is filled in a cylindrical cavity 5, whose length 1 is greater than the diameter d. A combustible mechanical cover 7 (foil) acts as a mechanical and moisture barrier and at the same time as an ignition distributor on the end face of the propellant charge. The impulse body 4 has, viewed in the firing direction A, recesses 8 in its end face, which serve for weight optimization or for weight reduction. On the same end face is a driver socket 12, which is part of the rear part 9 of a projectile. A front part 10 closes the projectile and delimits a hollow space which, in the firing direction A, is filled with an active substance 17. A closure pin 14 forms the rear-side barrier in this cavity and serves to balance the weight, ie, by dimensioning and selecting the material, the center of mass of the projectile can be adjusted. Integral to the rear part 9 is a thin-walled side guide 11 is present, which rests positively on the inner cylinder shell 2a and after the impulse transmission to the parts 9 and 10 assumes their axis-parallel guidance. The enclosed cavity 13 as well as the air space IIa are slightly compressed during the impulse transmission since the driver stub 12 is yielding; which increases the positive connection of the side guide 11.
Frontseitig ist das Teil 10 als Kugelkalotte 15 ausgebil- det; der Radius R an deren bombierten Oberfläche beträgt 155 mm. Zentriert und radial gesichert gegen Verdrehungen ist das Frontteil 10 durch äussere Stege 9? bzw. innere - Stege 9" welche aus dem Heckteil 9 ragen.On the front, the part 10 is designed as a spherical cap 15; the radius R at its cambered surface is 155 mm. Centered and secured radially against rotation, the front part 10 by outer webs 9 ? or inner - webs 9 "which protrude from the rear part 9.
Das Geschoss wird durch Züge 31 im Rohr 30 drallstabilli- siert. Hierzu schneiden sich die Züge 31 in ein radial ab¬ stehendes Führungsmittel, einen Führungsring 18, ein. Bei einer typischen Abschussgeschwindigkeit vo von 55 m/s ent¬ steht ein Anfangsdrall von 45 Umdrehungen pro Sekunde.The projectile is swirl-stabilized by ducts 31 in the pipe 30. For this purpose, the trains 31 intersect in a radially ab¬ standing guide means, a guide ring 18, a. At a typical launch speed of 55 m / s, there is an initial spin of 45 revolutions per second.
Die Draufsicht Fig. 2 zeigt wiederum die Patronenhülse 2, den Führungsring 18 sowie das frontseitige Geschossteil 10, mit schlitzartigen Ausnehmungen 16 und Entsteifungen 20 in den Teilen 10 und 15.The plan view Fig. 2 shows again the cartridge case 2, the guide ring 18 and the front-side projectile part 10, with slot-like recesses 16 and stiffeners 20 in the parts 10 and 15th
Die Ausgestaltung des Heckteils 9 ist der Fig. 3 und des Frontteils 10 der Fig. 4 zu entnehmen:The embodiment of the rear part 9 is shown in FIG. 3 and the front part 10 of FIG. 4:
In Fig. 3 ist eine relativ Breite Dichtlippe 9a ersicht¬ lich, welche die inneren Stege 9" überragt und auf dem In¬ nenraum 10a, Fig. 5, des Frontteils 10 kraftschlüssig auf¬ liegt und den Innenraum für den Wirkstoff 17 radial abdich- tet. Zudem ist die keilförmige Ausgestaltung der äusseren Stege 9' ersichtlich, welche der schlupffreien Drallüber¬ tragung vom Heckteil 9 auf das Frontteil 10 dienen.FIG. 3 shows a relatively wide sealing lip 9a, which protrudes beyond the inner webs 9 "and frictionally rests on the inner space 10a, FIG. 5, of the front part 10 and radially seals off the interior space for the active substance 17. tet. In addition, the wedge-shaped configuration of the outer webs 9 'can be seen, which serve for the slip-free swirl transmission from the rear part 9 to the front part 10.
Die schlitzartigen Ausnehmungen Fig. 4 und Fig. 5 weisen einen hohen Kerbfaktor auf und platzen beim Aufprall auf ein Ziel Z, Fig. 6, sofort auf (Sollbruchstellen) und set¬ zen dabei auf Grund des sich bildenden hydraulischen Drucks den Wirkstoff 17 frei, so dass sich in unmittelbarer Nähe aber auch in der Umgebung Schwaden S bilden.The slot-like recesses FIG. 4 and FIG. 5 have a high notch factor and burst immediately upon impact with a target Z, FIG. 6 (predetermined breaking points), thereby releasing the active substance 17 due to the hydraulic pressure forming, so that form S swaths in the immediate vicinity but also in the area.

In jedem Fall (ab 5 m Flugdistanz) wird eine Ener- giedichte von 9 J/cm2 nicht übertroffen, so dass bei Auf¬ prall des Geschosses auf Personen keine Hautverletzungen oder Brüche entstehen. Ein ungewollter Treffer am Kopf ei¬ ner Zielperson führt zu keinen schwerwiegenden Gesichts¬ bzw. Augenverletzungen, da die weiche Kugelkalotte einen äusseren Radius über 150 mm aufweist.Use distance is between 5 to 20 m, ie in the first shot is to hit a target of 20 x 20 cm at this distance safely. At a distance of 50 meters this applies to an area of 55 x 55 cm. In any case (from 5 m flight distance) an energy density of 9 J / cm 2 is not exceeded, so that no skin injuries or fractures occur when the projectile impacts on persons. An unintentional hit on the head of a target person does not lead to any serious facial or eye injuries, since the soft spherical cap has an outer radius over 150 mm.
Beim Abschuss des Geschosses 9, 10 überträgt sich die Ab¬ schussenergie nicht vollständig auf den Treiberstutzen 12, so dass der Impulskörper 4 ebenfalls aus dem Abschussrohr 30 austritt und in einer geneigten Flugbahn nach kurzer Di- stanz auf den Boden fällt. Die Füllmenge an Wirkstoff 17 sowie dessen Dichte lässt sich durch einen Massenausgleich am Verschlusszapfen 14, kompensieren. Der resultierende Massenschwerpunkt des Ge¬ schosses 9, 10 kann dadurch in allen denkbaren Fällen auf seine optimale Lage eingestellt werden.When launching the projectile 9, 10, the shot energy is not completely transferred to the drive nozzle 12, so that the pulse body 4 also emerges from the launching tube 30 and falls in an inclined trajectory after a short distance on the ground. The amount of active ingredient 17 and its density can be compensated by a mass balance on the closure pin 14. The resulting center of mass of the projectile 9, 10 can thereby be adjusted to its optimum position in all conceivable cases.
Sämtliche Komponenten sind an sich bekannt:All components are known per se:
Die Geschosshülse 2 besteht aus Polyethylen (PE) ; das Heck¬ teil 9 aus Polyacetal (POM) . Das Frontteil 10 ist EPDM (Äthylen-Propylen-Dien-Kautschuk) , welcher unter verschie- denen Produktebezeichnungen handelsüblich ist und eine sehr hohe Elastizität aufweist.- Dies ergibt die im Ziel ge¬ wünschte Vergrösserung des Wirkungsquerschnitts.The projectile sleeve 2 is made of polyethylene (PE); the Heck¬ part 9 made of polyacetal (POM). The front part 10 is EPDM (ethylene-propylene-diene rubber), which is commercially available under various product names and has a very high elasticity. This results in the desired cross-sectional increase in the target.
Der Impulskörper 4 aus einem handelsüblichen Kunststoff ho¬ her Dichte, wie beispielsweise Polyacetal oder Polyoxyme- thylen (Delrin = Warenzeichen der Firma DuPont, USA) . Zur Erhöhung der Masse kann er ggf. auch aus einer Aluminiumle¬ gierung gefertigt werden. Die zentrale Anordnung der Treib¬ ladung 6, mit den dargestellten geometrischen Verhältnis¬ sen, bewirkt eine konzentrische Energieübertragung und da- mit eine präzise Schussabgabe.The pulse body 4 made of a commercially available plastic of high density, such as, for example, polyacetal or polyoxyethylene (Delrin = trademark of DuPont, USA). To increase the mass, it may also be made of an aluminum alloy. The central arrangement of the Treib¬ charge 6, with the geometric relationships shown, causes a concentric energy transfer and thus a precise firing.
Nicht letale Wirkstoffe können auf Grund des zur Verfügung stehenden grossen Volumens hoch verdünnt sein und trotzdem die erwünschte Wirkung erzielen. Zur Markierung sind neben Farben auch an sich bekannte Duftstoffe denkbar, die bei Gesetzesbrechern eine nachhaltige Wirkung, auch in deren Umfeld verursachen. Ebenfalls sind chemische Markiermedien einsetzbar, die erst später mit physikalischen Mitteln er¬ kennbar werden, wie UV- Strahlung oder Halogendetektoren etc. B e z e i c h n u n g s l i s t eNon-lethal drugs can be highly diluted due to the large volume available and still achieve the desired effect. To mark next to colors and per se known fragrances are conceivable that cause a lasting effect in lawbreakers, even in their environment. It is also possible to use chemical marking media which are only later identifiable by physical means, such as UV radiation or halogen detectors, etc. List of drawings
