Abstract

In order to reduce significantly the effort involved in the logistics and making safe of destructive charges (100) containing hollow charges, intended particularly for bomb disposal by remotely controlled detonation, the invention proposes that the destructive charge (100) should not be kept, i.e. stored and transported, as a ready-assembled charge, but instead all components that are not relevant to safety, such as the preferably tubular casing element (2) of the destructive charge (100), a hollow charge insert (5) and the cap (6) or cover (22) intended for receiving the detonator, should be stored and transported separately as a construction kit (1, 1'). The destructive charge (100) is then only assembled on site, together with the explosive (12) that is required for the hollow charge and is available at the site and together with the electrical detonator, on condition that the person in charge of bomb disposal operations authorizes their use for blowing up the bombs.

Description

DESCRIPTION

Kit and method for producing a hollow charge containing Zerstörladung

The invention relates to a kit for producing a hollow charge containing Zerstörladung for non-contact destruction of ordnance. The invention further relates to a method for producing a discharge charge using such a kit.

From DE 36 23 240 C1 a Zerstörladung for non-contact ordnance disposal (EOD = Explosive Ordnance Disposal) by means of a shaped charge is known. In this case, the breakdown power of the hollow charge is chosen such that it penetrates though the shell of ammunition to be defused, however, the ammunition no longer brings to the detonation of their explosive charge. As a result, a relatively safe disposal of the ammunition by removing the explosive charge or by their burning done.

In DE 36 23 240 C1 is also mentioned to make the setting of the desired breakdown power of the hollow charge precise dosage of their plastic explosive only on site. However, this document can be found no evidence how such a Zerstörladung is constructed so that the dosage of explosives can be done on site. It is also mentioned in DE 36 23 240 C1, that in the dosage of the explosive on the spot inhomogeneities, such as bubbles in the explosive filling, resulting in an exact adjustment of the breakdown power in practice almost impossible.

Finally, it is known from EP 1 095 238 B1 to design the hollow charge deposit of the discharge charge as a projectile-forming charge, the deposit being made of a non-galvanically conducting, amorphous material. A disadvantage of the known, ready-mounted Zerstörladungen, inter alia, that with their storage and their transport, a high logistics effort and in terms of a possible loss of a high monitoring effort is connected.

DE 603 18 298 T2 discloses a device for destroying explosives. The plastic destruction mechanism consists of a cylinder provided with an axial tube serving to support the triggering means. During the charging process, the detonator (trigger means) can be occupied by a blind detonator. The charging process consists of loading a measured amount of plastic explosive into a cavity in the destructing mechanism that extends from the end of the blind detonator to the rear wall of the shaped charge liner. When the maximum amount of explosive is used, the leading edge of the high-load ring is located in the same plane or a few millimeters protruding from the edge of the destruction mechanism. The shaped charge liner and the explosive are held by a threaded consolidation ring which is screwed onto the destruction mechanism. If less explosive is used, at least one spacer ring between the inner bridge of the consolidation ring and the hollow charge insert is to be integrated. The filling with explosive material is such that it is introduced into the body from the open side and compressed, conventionally compressed by manual stamping, then further compressed by the consolidation ring acting on the front surface of the shaped charge liner. In the other filling process end stops are involved, to which the consolidation ring and any spacers must strike.

The invention has for its object to significantly reduce the logistics and security costs for Zerstörladungen.

This object is achieved in that the Zerstörladung not kept ready as a ready-mounted charge, ie stored and transported, but that all non-safety-critical components, such as the preferably tubular housing element of the Zerstörladung, the Hohtladungseinlage and provided for receiving the detonator cap, as Kit to be stored and transported separately. The Zerstörladung is then mounted on site, provided that each blasting authorized in ordnance disposal operations their use for non-contact wringing of Ammunition etc. is considered necessary. As an explosive for the hollow charge can then in the rain! In explosive ordnance operations already present malleable explosives, such as PETN (Nitropenta), Semtex (trade name for a Nitropenta and hexogen mixture of the Czech company Synthesia), C-4 (Composition consisting of 91% hexogen, 5.3% polyisobutylene + plasticizer ), etc., are used. As a detonator usually come electric detonators, namely U-detonator (insensitive) or HU igniter (highly insensitive) are used.

By using a kit according to the invention, the logistics and security costs for the corresponding Zerstörladungen is substantially reduced, since the individual parts of the kit are not subject to approval and monitoring. Furthermore, no shelf life periods must be observed.

In order to ensure a reproducible breakdown power of the destructive charge after their assembly, provided for igniter cap and a kit also associated loading aid are designed so that when mounting the Zerstörladung one hand, the axial position of the shaped charge liner can be accurately positioned and that on the other hand on the moldable Explosive pressure can be exerted that is sufficient so that after the pressing operation, the explosive positively against the wall portions of the tubular Gehäuseiementes, the shaped charge liner and the cap, so that bubbles in the explosive and air pockets between the explosive and the adjacent parts are safely avoided.

For this purpose, the loading aid comprises a base part and a top side adjoining the base part, preferably cylindrical upper part, the base portion facing away from the front portion is preferably conical and at least partially corresponds to the inner edge contour of the insert. The upper part of the loading aid can be introduced through the opening in the second end face into the tubular housing element and serves as an abutment in the pressing process of the explosive and for determining the distance of the shaped charge insert from the second end face of the tubular housing element.

It has proven to be advantageous if the tubular housing element of the kit is hardboard, so that when using the destruction charge no Significant lateral fragmentation occurs and the danger zone when using the charge is lower than in comparable known Zerstörladungen.

The hollow charge insert may be a metal, preferably copper. However, if a metal-free destructive charge has to be used for the elimination of electronic ordnance in order to prevent an influence on the weapon by the metal insert, the hollow charge insert may consist of a non-metal, preferably glass.

It has also proven to be useful if the kit for non-contact wringing of ordnance includes wires with which - if necessary - spacers (for example, a three-leg) can be formed, which are then attached to the housing element of the fully assembled Zerstörladung.

For mounting the destruction charge with the aid of the kit according to the invention, the base part of the loading aid is first positioned on a solid surface. Subsequently, the hollow charge insert of the kit is pressed with the front portion of the upper part through the opening of the second end face of the tubular housing member in the predetermined by the minimum distance (stand off) of Hohliadungseinlage to be destroyed ordnance position. Then, the existing explosive is preformed and introduced through the opening of the first end face into the preferably tubular housing element. Subsequently, the cap is pressed with its designed as a press die lower part against the explosive and then used as U or HU igniter trained electric detonator in the axial bore of the cap.

It has proved to be advantageous if the pressure exerted on the explosive pressure is chosen such that the explosive 1 to 2 mm rises in the axial bore of the cap, so that a reliable ignition of the explosive is ensured by the detonator.

Alternatively, a loading die can be used, which can also serve as a means of transport of the other parts of the kit. Further details and advantages of the invention will become apparent from the following, with reference to figures explained Ausführungsbeispieien. Show it:

1 is a kit according to the invention consisting of a tubular housing element, a Hohüadungseinlage, a cap and a charging hook

Fig. 2 is a partially shown in longitudinal section destruction charge, which was assembled from the kit of FIG. 1 and a moldable explosive and an electric detonator on site and

3 shows a destructive charge with a spacer formed from three wires,

4 is a transport diagram of the kit,

Fig. 5 is an illustration of a loading die.

In Fig. 1, 1 denotes a kit for producing a hollow charge-containing Zerstörladung. The kit 1 comprises a preferably tubular housing element 2 made of hard cardboard with a first end face 3 and a second end face 4. In addition, the kit 1 comprises a tubular shaped element 2 adapted conical hollow charge insert 5 preferably made of copper and serving as igniter pick-up cap 6. Die Cap 6 includes an axial bore 60 for receiving an electric detonator and has a base 61 which is formed as a press brake. In addition, the kit 1 is associated with a loading aid 7, which has a base part 8 and an adjoining the base part 8 upper part 9, the base part 8 facing away from the front portion 10 is conical and at least partially corresponds to the inner conical edge contour of the shaped charge insert 3. The upper part 9 is matched in shape to the shape of the housing element 2. If the housing element 2 is tubular, then the upper part 9 is cylindrical, etc.

If a destructive charge 100 is to be produced locally from the kit 1 and an existing moldable explosive and a detonator, the base part 8 of the loading aid 7 can first be positioned on a solid base 1 (FIG. 2). Anschiießend the shaped charge liner 5 with the front portion 10 of the upper part 9 through the opening of the second end face 4 of the housing element 2 in the by the minimum distance (stand off) of the shaped charge liner 5 to be destroyed to the center of combat! pressed predetermined position.

Then the explosive is preformed and the preformed explosive 12 is introduced through the opening of the first end face 3 into the housing element 2.

Subsequently, the cap 6 is pressed with its trained as a press die base 61 against the explosive 12, such that the force exerted by the cap 6 on the explosive pressure enough to push explosives 1 to 2 mm in the axial bore 60 of the cap 6.

Finally, a suitable detonator (U or HU igniter) 13 is inserted into the axial bore 60 of the cap 6.

Since it is important to note that a certain minimum distance (stand off) to the weapon must be present in the non-contact destruction of warheaded ordnance, it is often necessary for the destructive charge 100 to be attached to a corresponding spacer in front of the ordnance to be destroyed.

Such a spacer 15 formed of wires 14 is shown in FIG. 3 together with the fully assembled destruction charge 100.

Fig. 4a shows the kit 1 with its housing or housing element 2 in the transport position. The representation in Fig. 4b is a Schnittdarsteliung in section A-A of Fig. 4a. Clearly missing here is the explosives.

In Fig. 5, a loading die 20 is shown. The loading die 20 comprises a housing 21 into which the housing element 2 of the kit can be inserted. A Pappröllchen 2 'or the like can also be used for a length compensation between the dimensions of the housing 21 and the housing element 2 of the kit V. The housing 21 of the loading die 20 can be closed by two covers 22, 23. Embedded in the lower cover 23 is a conical punch 24, which points in the direction of the housing element 2 when closing the opening 25, 26. The stamp 24 is in turn adjustably inserted in the lid 23 and can be secured in its final position by means of nuts 27, 28, but at least one. Integrated in the upper cover 22 is a counter-holder 29 which likewise extends into the housing element 2 of the kit V when the destructive charge containing a shaped charge is produced. In or on the counter-holder 29 engages the explosive charge 21 forming ram 61 on or. The counter-holder 29 has a passage or axial bore 30 and is also secured by nuts 31, 32, but at least one. Alternatives to securing with a nut, as well as for the stamp, a sap, etc. be. Those are well known to the skilled person.

The individual steps for the production can proceed similarly as described for the loading aid 7. Thus, the lid 23 can be screwed or latched onto the housing 21. With the help of the ceiling! 23 contained punch 24, the previously introduced hollow charge insert 5 is pressed into the housing member 2 in the predetermined position, the punch 24 secured. The preformed explosive 12 can preferably be introduced into the housing element 2 through the upper opening 22 of the loading die 20 and the first end face 3. Again, the punch 24 is used after the introduction of the explosive 12 in the housing element 2 this form fit to the wall portions of the adjoining housing element 2, the hollow charge insert 5 and the underside of the lower part 61 to press. By closing the upper lid 22, the counter-holder 29 engages the lower part 61 and centers it. The counter bracket 29 may be omitted if the lower part 61 directly to the ceiling! 22 is connectable. The suitable detonator (U or HU detonator) 13 is introduced through a passage or axial bore 30 in the counter holder 29 or in the cover 22. This destructive charge 100 'can also be introduced into a spacer 15 according to FIG. 3.

Alternatively, the manufacture or introduction of the individual parts of the kit V can also take place only through one of the openings 25, 26. List of Reference Numerals, 1 'kit
