Description

Sprengstoffanordnung zur Erzeugung einer linienförmigen Detonationsfront Mit der Fortentwicklung der Anwendungsmöglichkeiten von Sprengstoffen treten besondere Probleme der Initiierung der Sprengstoffe auf. So ist z. B. eine dieser Aufgaben das gleichzeitige Initiieren einer Sprengstoffplatte von einer Seite her durch einen einzigen Zünder. Diese Zündungsart ist z. B. bei der flächenmäßigen Verbindung von Metallplatten erforderlich.Explosives arrangement for generating a linear detonation front With the further development of the possible uses of explosives, special ones occur Problems of initiating the explosives. So is z. B. one of these tasks the simultaneous initiation of an explosive plate from one side by a single detonator. This type of ignition is z. B. in the planar connection of Metal plates required.

Gegenstand der vorliegenden Erfindung ist daher eine Sprengstoffanordnung zur Erzeugung einer linienförmigen Detonationsfront, die dadurch gekennzeichnet ist, daß man Sprengstoffe mit verschiedener Detonationsgeschwindigkeit in der Weise anordnet, daß die Schenkel eines Dreiecks aus einem Sprengstoff mit hoher Detonationsgeschwindigkeit bestehen, die einen Sprengstoff mit geringerer Detonationsgeschwindigkeit unter einem solchen Winkel einschließen, daß alle Detonationsfronten gleichzeitig die Grundlinie erreichen.The present invention therefore relates to an explosives arrangement for generating a line-shaped detonation front, which is characterized is that you can get explosives with different detonation speed in the way ordered that the legs of a triangle made of an explosive with high detonation speed consist of an explosive with a lower detonation rate enclose such an angle that all detonation fronts simultaneously the Reach baseline.

Zur Erzielung einer linienförmigen Detonationsfront sind bereits dreieckige Sprengstoffplatten bekannt, die entsprechend angeordnete Lochungen oder bandförmige oder winkelförmige Ausschnitte tragen. Für jede gewünschte Endbreite der Detonationsfront benötigt man dabei aber verschieden große Dreiecke, so daß eine kostspielige Lagerhaltung eines umfangreichen Sortiments notwendig ist. Außerdem entsteht bei der Herstellung dieser Platten sehr viel unerwünschter Abfall.Triangular ones are already used to achieve a line-shaped detonation front Known explosive plates, the correspondingly arranged perforations or band-shaped or wear angular cutouts. For any desired final width of the detonation front but you need triangles of different sizes, so that expensive storage an extensive range is necessary. It also arises during manufacture these panels have a great deal of unwanted waste.

In der Zeichnung ist eine solche Anordnung dargestellt. Durch den Zünder 1 wird der Sprengstoff 2 mit der höheren Detonationsgeschwindigkeit gezündet. Die Detonationsfront schreitet von diesem Punkt gleichmäßig nach allen Richtungen fort und trifft in Punkt 4 auf den Sprengstoff 3, welcher eine niedrigere Detonationsgeschwindigkeit hat. In diesem Sprengstoff schreitet die Detonation in Richtung auf 5 mit einer geringeren Geschwindigkeit, als die Detonation von 1 auf 6 zu. Der Winkel c#, welcher die Länge des Weges bestimmt, muß so gewählt sein, daß sämtliche Detonationsfronten im selben Augenblick auf der Grundlinie auftreffen. Als Beispiel sei als Sprengstoff 1 eine Explosivfolie mit einer Detonationsgeschwindigkeit von 7500 m/sec und als Sprengstoff 2 ein Nitropenta, mit 10 % Montanwachs phlegmatisiert, mit einer Detonationsgeschwindigkeit von 4500 m/sec, genannt. Der Winkel x muß dann 108° betragen. So ist es möglich, eine gerade Detonationsfront - gleichgültig welcher Länge - auf einfache Art und Weise herzustellen, indem man Folienstreifen zu einem Dreieck auslegt und darin das Nitropenta einbringt.Such an arrangement is shown in the drawing. Through the Detonator 1 detonates the explosive 2 with the higher detonation speed. From this point the detonation front advances evenly in all directions continues and hits the explosive 3 in point 4, which has a lower detonation speed Has. In this explosive, the detonation progresses towards 5 with a slower than the detonation from 1 to 6. The angle c #, which one determines the length of the path must be chosen so that all detonation fronts hit the baseline at the same instant. As an example, consider explosives 1 an explosive film with a detonation speed of 7500 m / sec and as Explosive 2 a nitropenta, phlegmatized with 10% montan wax, with a detonation speed of 4500 m / sec. The angle x must then be 108 °. So it is possible a straight detonation front - regardless of its length - in a simple manner and Way to manufacture by laying out strips of foil to form a triangle and inside brings in the nitropenta.
