Die Aufgabe, eine den höchsten Genauigkeitsansprüchen genügende Detonationswelle in einer Sprengladung auszulösen, bedingt einerseits die Forderung, die Detonationswelle geometrisch exakt beginnen zu lassen, andererseits die Intensität der Initiierung so hoch wie möglich zu sichern, damit sich die Detonationswelle nach jeder Richtung mit der vollen Geschwindigkeit fortpflanzt.The task of producing a detonation wave that meets the highest demands for accuracy in one Triggering an explosive charge requires, on the one hand, that the detonation wave begin geometrically precisely to let, on the other hand, ensure the intensity of initiation as high as possible so that yourself the detonation wave propagates at full speed in each direction.
Nur die gleichzeitige Beachtung beider Kriterien gewährleistet eine einwandfreie Ausbildung der Detonationswelle. Only if both criteria are observed at the same time can the detonation wave develop properly.
Versuche haben gezeigt, daß Hohlladungen besonders empfindlich gegen unsymmetrische Detonationswellen sind. Aus diesem Grunde hat man versucht, die Detonationseinleitung möglichst punktförmig zu gestalten, z. B. durch Wahl eines dünnen stabförmigen Detonators. Bekanntlich gelangt man hierbei jedoch rasch an einen Grenzdurchmesser des Detonatorstabes, da unterhalb eines bestimmten Durchmessers, der von den Eigenschaften des Sprengstoffes bzw. der inerten Verdammung (Metallhülse des Detonators) abhängt, keine Detonation mehr möglich ist.Experiments have shown that shaped charges are particularly sensitive to asymmetrical detonation waves. For this reason one has tried to design the detonation initiation as punctiform as possible, z. B. by choosing a thin rod-shaped Detonators. As is well known, however, this quickly leads to a limit diameter of the detonator rod, because below a certain diameter, depending on the properties of the explosive or the inert dam (metal sleeve of the detonator) depends, detonation is no longer possible.
Je besser man also punktförmig initiiert, desto schwächer wird die Intensität der Detonationswelle, so daß verschieden lange Anlaufstrecken in den einzelnen Richtungen die Folge sind. Das Ergebnis ist daher eine zufällig geformte, d.h. unsymmetrische Detonationswelle. Erhöht man nunmehr den Durchmesser des Detonatorstabes, so bessert sich die Symmetrie des Detonationsanlaufs, weil die Initiierungsintensität gewachsen ist, der Anfangspunkt der Detonationswelle ist aber nunmehr im ganzen Querschnitt der Berührungsfläche des Detonatorstabes gleich wahrscheinlich. Auch in diesem Falle kann es daher zu keiner symmetrischen Detonationswelle kommen, weil der Anfangspunkt unbestimmt bleibt.The better one initiates point-like, the weaker the intensity of the detonation wave becomes, so that different lengths of approach in the individual directions are the result. The result is hence a randomly shaped, i.e. asymmetrical, detonation wave. If you now increase the diameter of the detonator rod, the symmetry of the detonation start improves because the initiation intensity has grown, but the starting point of the detonation wave is now in the entire cross-section the contact surface of the detonator rod is equally likely. It can therefore also in this case do not come to a symmetrical detonation wave because the starting point remains indefinite.
Die vorliegende Erfindung vermeidet die geschilderten Nachteile und führt zu einem Zündsystem mit exakt punktförmiger Einleitung der Detonation mit so großer Initiierungsintensität, daß eine nach allen Richtungen gleichförmige Detonationsfortpflanzung gesichert ist.The present invention avoids the disadvantages described and leads to an ignition system exact punctiform initiation of the detonation with so great initiation intensity that one after all Directions uniform detonation propagation is assured.
Eine Lösung dieser Aufgabe erfolgt gemäß der Erfindung dadurch, daß ein primär und konventionell zu zündender Ladungsteil mit relativ langsamer Detonationsgeschwindigkeit einen zu einer Spitze ausgezogenen Zündempfängerteil der Sprengladung mit relativ hoher Detonationsgeschwindigkeit umfaßt, wobei die Zündung an beliebiger Stelle nahe der Ladungsachse im langsameren Ladungsteil erfolgt.A solution to this problem takes place according to the invention in that a primary and conventional part of the charge to be ignited with a relatively slow detonation speed one drawn out to a point Includes detonation receiver part of the explosive charge with a relatively high detonation speed, the ignition takes place at any point near the charge axis in the slower part of the charge.
