Description

The invention relates to a device and a method for clearing of mines, ammunition, especially mittelkalibrigen format, and pyrotechnic ammunition or objects.

The ammunition destruction etc. takes place in the best known manner by initiating the same. This is usually done by cutting or shaped charges. Pyrotechnic ammunition or open-access explosives are lit with so-called EOD (Explosive Ordnance Disposal) igniters. This kind of ignition is often not well targeted, too weak and too undefined to ensure safe ignition and implementation. This is the reason that dispensed with such lighters and the ammunition, etc. but rather blown up by cutting charges in the air.

Such a method is known from DE 36 19 332 C2 known. With the application of an impact or hollow charge, the explosive of the explosive device is ignited by ignition transmission and / or via the ignition chain. This method is often used even when there is little time available and there is insufficient information about the explosive device and in particular the ignition system.

In the DE 689 10 454 T2 ( EP 0 360 234 B1 ), a hose filled with explosive material is brought into the area of possible mines so as to provide a safe path through a minefield. Due to the detonation of the material, a pressure wave is generated, which serves to trigger the explosive in the mines. The explosive material is a nebulizable fuel that is then detonated above the minefield.

The DE 103 07 639 B3 describes a method and apparatus for in-situ removal of unreacted munitions. The coat of ammunition is first melted or burned by means of a first gas jet. Subsequently, the jacket is perforated by means of a second, rich in oxidizing substances gas jet, brought the ammunition charge to burn. Both beams are generated by an active charge set.

The DE 10 2007 018 137 B3 goes a similar way, whereby also here to neutralize explosive devices, a burning of the explosive device is sought. In this case, there is a punctual positioning and alignment of a high-temperature generating, designed as a remote-controlled nozzle source so that the explosive is hit safely, but the detonator is not in the immediate vicinity. As a result, the explosive itself is burned by the heat, the detonator in turn no longer finds explosives. The high temperature is generated by a gas flame.

In practice, these new ways have shown to be practicable, but in the implementation of a high hardware cost is to be provided.

The GB 2 312 864 A1 discloses an apparatus for cutting relatively hard and durable materials, such as metals, using a thermite composition. The cutter is formed by a container, the container comprising the shape of the cut to be made along one side of the container. Associated with this cut is a cover which ruptures upon actuation of the device by the thermite charge within the container. The thermite charge is ignited in turn.

The US 3,109,369 A1 deals with a device for removing enveloped explosives. This includes a container for receiving a thermite charge. Bottom side, a narrow opening is closed with a cap, which is destroyed when the charge ignites.

From the US Pat. No. 6,805,832 B2 For example, an improved nozzle of a thermite cutting torch is known for guiding an arc. This ensures that the burner is self-centering against the workpiece.

The DE 36 23 240 C1 uses a shaped charge to defuse ammunition of different nature, while the DE 102 01 191 B4 a system for generating the reaction of an ammunition using different charges and a hollow charge initiating this published.

The invention therefore has the task of demonstrating a simple variant, with a targeted destruction of ammunition, etc. can take place.

The problem is solved by the features of claim 1. Advantageous embodiments are listed in the subclaims.

The invention is based on the idea of designing an EOD lighter such that it can specifically direct the ignition energy to the object to be destroyed. This can be done both punctiform and linear. Again, a high temperature / heat is generated, which ensure the lighting.

In continuation of the invention, it is provided that ammunition or explosives that are not exposed and are surrounded by a halfway thick-walled shell, are destroyed by such a lighter. By a safe ignition, these can then burn or deflagrate without being implemented detonatively.

As a primer preferably a Thermitladung is used, which burn off particularly hot and energetic by additives such as inorganic oxides or sulfur. The charge is pressed in a container of aluminum or the like, for example, which is surrounded by a steel container. Altarnativ the charge can also be housed directly in the steel container, for example, here by pressing. The steel container has in its outer wall via a slot-like opening and the bottom side via a hole or a slot-like opening. About this steel container, a second steel container is preferably mounted, which also has a slot-like opening in the outer wall and a differently positioned hole or slot-like opening in the ground. By this construction, it is possible in a simple manner to produce by twisting both containers a common slot in the outer wall (linear exit) or a common opening in the bottom (punctiform exit). Alternative constructions for achieving this function are well known to those skilled in the art.

The charge itself preferably has an inner channel, which may optionally be arranged eccentrically. Through this channel, the energy can be guided in a targeted manner in the area of the bottom-side exhaust opening. Likewise, a free access to the outer cleft is created.

At the front, the charge can be provided with an ignition charge, for example of aluminum and iron oxide. This receives upwards a connection for an electric lighter or an access for a Leitfire ignition. The bottom area and / or the lid area should be protected by a ceramic or clay insert or the like against the intense heat (temperature range <2800 ° C.) of the thermodischarge, so that no further, in particular unwanted, exhaust openings occur. In addition, a torsional or rolling bolt should be integrated. This may be on the ground and / or front side existing pins or nubs on the (the) container outer surface (s), so that the body can not roll away from the desired position. Alternatively or additionally, eyelets for attaching lashing straps o. Ä. For connecting the lighter with the object to be destroyed are provided.

Reference to an embodiment with drawing, the invention will be explained in more detail.

It shows:

1 a neutralization body in a full view,

2 the neutralization body 1 in a sectional view,

In 1 is a neutralizing body 10 shown, the, how 2 shows, by two composable body, a kind of can 1 and a shell 4 , is formed, the can 1 in the shell 4 is plugged.

The tin 1 includes at the bottom of a funnel-shaped base 3 that the space for an active mass above it 2 limited. A detonator 5 who is in the active mass 2 reaches into the can 1 preferably screwed.

In the shell 4 as well as the can 1 are preferably each a slot-shaped opening 11 . 12 introduced, which are superposed in this representation, that the active agent 2 could initiate laterally (longitudinal or transverse, depending on the design of the openings) after initiation. Accordingly covers the shell 4 in this illustration at the bottom of the body 10 the funnel exit 13 , for a selective outlet of the active mass 2 would be open. For opening the shell has 4 a separate opening, not shown, by twisting the shell 4 to the can 1 an opening to the funnel outlet 13 would create. With 6 screws are marked.

As active substance 2 a Thermitladung is preferred, which burns particularly hot and energetic by additives such as inorganic oxides or sulfur.
