Abstract

Durch Gehalt von wenigstens 5 % Oktogen zum Hexogen-Sprengstoff wird ein unempfindliches Verhalten gegen hohe thermische Belastungen (Fast Cook Off) erhalten.By containing at least 5% octogen to the hexogen explosive, an insensitive behavior against high thermal loads (Fast Cook Off) is obtained.

Description

Die Erfindung bezieht sich auf einen Hexogen-Sprengstoff nach dem Oberbegriff des Anspruchs 1.The invention relates to a hexogen explosive according to the preamble of claim 1.

Ein derartiger Sprengstoff geht aus der DE 37 39 191 A1 hervor. Dort ist ein gießbarer Sprengstoff mit einem Kunststoffbinder beschrieben.Such an explosive can be found in DE 37 39 191 A1. There is a pourable explosives described with a plastic binder.

Entsprechend der technischen Lieferbedingung des Bundesamtes für Wehrtechnik und Beschaffung in Deutschland, TL 1376-0800, sind die Bedingungen für die geforderte Unempfindlichkeit beschrieben. Demzufolge darf ein, in einem Behältnis, wie Geschoßkörper, eingeschlossener Sprengstoff bei Beschuß oder thermischer Einwirkung das Behältnis nicht aufreißen. Zugelassen ist als maximale Reaktion nur das Abbrennen, wobei ein zylindrischer Behälter ganz bleiben muß, jedoch darf der Boden aufreißen.According to the technical delivery conditions of the Federal Office of Defense Technology and procurement in Germany, TL 1376-0800, are the conditions for the required insensitivity described. Accordingly, one in one Container, such as a projectile body, trapped explosives when bombarded or Do not tear open the container due to thermal effects. Is approved as maximum reaction only burning, being a cylindrical container entirely must remain, but the floor may tear open.

Dementsprechend liegt der Erfindung die Aufgabe zugrunde, einen Hexogen-Sprengstoff vorzuschlagen, der die o.g. Bedingung erfüllt.The invention is accordingly based on the object of a hexogen explosive propose that the above Conditions met.

Die Erfindung löst diese Aufgabe entsprechend den kennzeichnenden Merkmalen des Anspruches 1. Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.The invention solves this problem in accordance with the characterizing features of claim 1. Advantageous developments of the invention are See subclaims.

Erfindungsgemäß wird der Sprengstoff in überraschenderweise unempfindlicher, jedoch leistungsstärker. According to the invention, the explosive is surprisingly less sensitive, however more powerful.

Gemäß der Erfindung ist als Sprengstoff der Hexogentyp B einsetzbar. Dieser ist kostengünstig und umweltfreundlich.According to the invention, the hexogen type B can be used as the explosive. This is inexpensive and environmentally friendly.

Durch den Anteil von Oktogen beim Hexogentyp B von wenigstens 5 % zum Sprengstoff wird erreicht, daß die in einem Behältnis angeordnete Sprengladung nach seiner Entzündung nicht progressiv abbrennt. Der Zylinder bleibt im wesentlichen erhalten. Lediglich Schwachstellen, wie Verschlußkappen, werden abgelöst. Es bildet sich keine Luftstoßwelle aus.Due to the percentage of octogen in hexogen type B of at least 5% to Explosive is achieved that the explosive charge arranged in a container does not burn progressively after its inflammation. The cylinder remains in the get essential. Only weak points, such as caps, are replaced. No air blast wave forms.

Der Wirkmechanismus der Erfindung beruht auf einer Phasenänderung des Oktogens, ab einer Temperatur von 167°C. Dadurch erfolgt eine schlagartige Volumenvergrößerung, die an vorgesehenen Sollbruchstellen oder Trennstellen zur Wirkung kommt.The mechanism of action of the invention is based on a phase change of the Oktogens, from a temperature of 167 ° C. This causes an abrupt Volume enlargement, the intended breaking points or separation points comes into effect.

Die Erfindung ist für Sprengstoffe mit reinem Hexogentyp A einsetzbar. Ebenso für die verschiedenen Herstellungsverfahren für Sprengstoffe, nämlich die im Slurry- oder im Lösungsmittel-Verfahren hergestellten Sprengstoffe. Das Anwendungsgebiet umfaßt sowohl gegossene Sprengstoffladungen als auch gepreßte Sprengstoffladungen.The invention can be used for explosives with pure hexogen type A. As well for the various manufacturing processes for explosives, namely those in Slurry or solvent-based explosives. The Field of application includes both cast explosive charges as well pressed explosive charges.

Insbesondere eignet sich die Erfindung für gepreßte unempfindliche Sprengstoffmischungen, bei denen grob- und feinkörnige Sprengstoffkristalle durch ein Bindersystem, bestehend aus einem Weichmacher wie DOA und HYTEMP® gebunden ist, siehe hierzu die am selben Tag eingereichte Patentanmeldung mit dem Aktenzeichen ..... .The invention is particularly suitable for pressed insensitive Explosive mixtures in which coarse and fine-grained explosive crystals through a binder system consisting of a plasticizer such as DOA and HYTEMP® is bound, see the one submitted on the same day Patent application with the file number ......

Die erfindungsgemäße Wirkung setzt bereits bei einem Oktogen-Anteil von 5 % ein, wobei der Anteil sich bis 100 % erstrecken kann.
