Abstract
Description
Die Erfindung betrifft eine strömungsoptimierte Oberflächengestaltung zur Erzielung einer höheren Fluggeschwindigkeit und -reichweite für Projektile aus Metall mit einem Durchmesser bis 6 mm, die mittels komprimierter Luft oder Gasen aus Gewehren oder Pistole verschossen werden.The The invention relates to a flow-optimized surface design to achieve a higher Airspeed and range for metal projectiles with a diameter up to 6 mm, which by means of compressed air or Gases are fired from rifles or pistols.
Es ist bekannt, daß Projektile, die mittels komprimierter Gase oder Luft verschossen werden, eine möglichst glatte Oberfläche aufweisen.It it is known that projectiles, which are fired by means of compressed gases or air, one preferably smooth surface exhibit.
Es ist ferner bekannt, daß die Oberfläche von Golfbällen zur Erzielung einer größeren Flugweite mit kleinen, über die gesamte Oberfläche verteilten Vertiefungen ausgestaltet wird. Durch diese Vertiefungen erreichen diese Golfbälle eine gegenüber Golfbällen mit glatter Oberfläche mehrfache Flugweite.It It is also known that the surface of golf balls to achieve a greater range with little, over the entire surface distributed depressions is configured. Through these depressions reach these golf balls one opposite golf balls with a smooth surface multiple flight distance.

Bei den üblicherweise aus zwei, mit den spitzeren Enden zusammengesetzten, Kegelstümpfen aus Metall bestehenden Projektilen für Luftgewehre- und Pistolen mit einem Durchmesser zwischen 4,5 und 6 mm ist jedoch zum einen aus fertigungstechnischer Sicht eine Ausformung von Vertiefungen oder Erhöhungen auf der gesamtem Projektiloberfläche nur sehr schwer bis unmöglich zu ralisieren. Zum andern ist eine Ausformung von Vertiefungen oder Erhöhungen auf der gesamtem Projektiloberfläche wegen der abdichtenden Funktion einzelner Projetilbereiche an der Wandung des Rohres der Waffen, beziehungsweise wegen des durch Vertiefungen oder Erhöhungen in diesen Bereichen ermöglichten wirkunslosen Vorbeiströmen des Luft- oder Gasdruckes am Projektil, nicht erwünscht.at usually of two truncated cones made of pointed ends Metal existing projectiles for Air rifles and pistols with a diameter between 4.5 and 6 mm, however, on the one hand from a manufacturing point of view, a molding of depressions or elevations on the entire projectile surface only very difficult to impossible to rationalize. On the other hand is a formation of depressions or increases on the entire projectile surface because of the sealing function of individual projectile areas at the Wall of the tube of weapons, or because of by depressions or raises in these areas irresistible streaming by the air or gas pressure on the projectile, not desired.
Aufgabe der Erfindung ist es, unter Eliminierung der genannten Nachteile, durch eine optimale Gestaltung die Flugweite und Präzision der Projektile wesentlich zu erhöhen. Dabei sollen die zur Herstellung der Projektile erforderlichen Maschinen, Werkzeuge und Einrichtungen weitestgehend weiterverwendet werden können.task the invention is, with elimination of the disadvantages mentioned, by an optimal design the flight distance and precision of the Significantly increase projectiles. The machines required for the production of the projectiles, Tools and facilities are widely used can.
Zur Lösung dieser Aufgabe ist es vorgesehen, nur in den in Flugrichtung liegenden Teilbereichen der Oberfläche der Projektile definierte Vertiefungen auszuformen, unter Auslassung der Bereiche, die zu Dichtungszwecken auf dem gesamten Umfang des Projektils an der Wandung des Rohres der Waffe anliegen müssen und/oder aus fertigungstechnischen Gründen nur mit erhöhtem und wirtschaftlich nicht vertretbarem Aufwand mit den Vertiefungen versehen werden können. Die Formen und Abmessungen der Vertiefungen können, je nach dem, in welchem Teilbereich des Projektils sie ausgeformt werden, variieren.to solution this task is provided only in the direction of flight Subareas of the surface Forming the projectiles defined wells, with omission the areas used for sealing purposes on the entire circumference of the Projectile must rest against the wall of the tube of the weapon and / or for manufacturing reasons only with increased and economically unreasonable effort with the wells can be provided. The shapes and dimensions of the depressions may vary depending on which Part of the projectile they are shaped vary.
Im Folgenden werden an Hand der Abbildungen verschiedene Ausführungsbeispiele der erfindungsgemäßen Projektilgestaltung näher erläutert.in the Various embodiments will be described below with reference to the drawings the projectile design according to the invention explained in more detail.

Ebenso können am Ende des hinteren Kegelstumpfes Vertiefungen wie an der abgerundeten Spitze ausgeformt werden.As well can at the end of the rear truncated cone depressions as at the rounded tip be formed.
Da
die erfindungsgemäßen Projektile
im Allgemeinen, im Gegensatz zu einem Golfball, eine stabile Flugbahn
ohne Rotation um die Hoch- oder Querachse aufweisen, können die
Vertiefungen (
Die durch die einzelnen Vertiefungen in der Oberfläche der Projektile gebildeten Kanten verursachen ein Abreissen der Luftströmung udn erzeugen Luftverwirbelungen im Grenzbereich zwischen Projektil und Umgebungsluft wodurch der Luftwiderstand des Projektils verringert wird. Dies hat zur Folge, daß die Geschwindigkeit des Projektils langsamer abnimmt und die Flugbahn des Projektils insbesondere im Bereich der für mit Gasdruck betriebenen üblichen Schußdistanz weniger abfällt und somit präzisere Treffer möglich sind.The formed by the individual depressions in the surface of the projectiles Edges cause the airflow to break off and generate air turbulence in the boundary between projectile and ambient air causing the Air resistance of the projectile is reduced. As a consequence, that the Speed of the projectile decreases more slowly and the trajectory of the projectile, in particular in the area of the usual shot distance operated with gas pressure less drops and thus more precise hits possible are.
Da für die Herstellung der findungsgemäßen Projektile lediglich einzelne, formgebende Werkzeug-/Maschinenteile ausgetauscht werden müssen, können die Projektile auf den vorhandenen Maschinen ohne größere Änderungen und ohne wesentliche Mehrkosten hergestellt werden.Since only individual, forming tool / machine parts must be replaced for the production of the inventive projectiles, the projectiles on the existing machine be produced without major changes and without substantial additional costs.
