Definitions
- the invention is concerned with a neutralization body for ammunition destruction and for clearing anti-tank mines.
- WO 03/006198 A1 publishes a nozzle of a thermite cutting torch for guiding an electric arc. This ensures that the torch is held in a self-centering manner against the workpiece. It is suggested to focus the cutting flame.
- the nozzle has an elongated opening, whereby a maximum flow of the cutting flame is provided to the desired location of the cut on the workpiece.
- DE 103 07 639 B3 describes a method and a device for the in-situ removal of unreleased ammunition.
- the shell of the ammunition is first melted or burned by means of a first gas jet generated by a first pyrotechnic charge charge.
- the jacket is perforated by a second gas jet, which is rich in oxidizing substances and generated by a second pyrotechnic charge, and the ammunition charge is burned up.
- Known active units contain a so-called kindling fire, consisting of a shaped body with a cutting charge and an ignition for generating a pyrotechnic flame, a so-called pyroflame.
- the pyroflame ignites the explosives in the ammunition or the mines within them.
- anti-tank mines are usually triggered without contact. Newer anti-tank mines can also be implemented when touched.
- a dismantling device for an explosive charge of a warhead can be found in DE 10 2009 017 160.
- a switchable cylindrical active charge of a warhead with a casing forming splitter and a tubular holder for a large number of pellets arranged in a distributed manner is presented.
- the active charge there is provided a cavity running along a main axis of the active charge, in which either at least one ignition device is arranged displaceably therein or stationary ignition devices are arranged at least in the area of the main axis.
- a neutralizing body for destroying ammunition or the like is disclosed in DE 10 2009 021 820 B4. This is characterized by the fact that it can specifically direct the ignition energy to the object to be destroyed. This happens point-like, alternatively also line-like.
- a thermite charge is preferably used as the ignition means, which burns down particularly hot and energetically due to the additives.
- the load itself preferably has an inner channel, which can optionally also be arranged eccentrically. The energy can be directed through this channel into the area of the blow-out opening on the bottom.
- the front of the charge is provided with an ignition charge.
- the invention takes up the idea of a pyrotechnic charge with which high heat (> 2000 ° C) can be generated.
- high heat > 2000 ° C
- iron filings or the like are added to the pyrotechnic mixture. These additives are used to scratch and thin the surface of the object to be destroyed.
- a gas image is also introduced in the pyrotechnic charge or in the pyrotechnic mixture.
- This gas image has the task of generating pressure within the active unit or the neutralization body.
- the gas former can be a potassium nitrate.
- the amount of gas forming on the pyrotechnic charge or on the pyrotechnic mixture should be proportionally between 5% and 18%. By choosing the exact amount, the pressure can be adjusted as required.
- Another approach is the design of a closure cap. This is designed in such a way that the required energy can be focused on a clearly defined area on the object.
- the closure cap has a nozzle-like shape. This nozzle or nozzle shape runs on the inside of the closure cap towards the opening.
- This nozzle shape allows an internal pressure to be built up inside the closure cap. This internal pressure contributes to the fact that a pyroflame emerges from the neutralization body under pressure. An internal pressure generated in the nozzle thus makes it possible for the pyroflame to shoot out of the cap. This means that an effective conversion of the pyrotechnic charge and thus an optimal pyroflame can be created. After the neutralization body has worked, only the sleeve and the nozzle remain on site.
- a thermite set can be used as the pyrotechnic set, which is already referred to in DE 10 2009 021 820 B4. It is also pointed out here that a thermite charge due to additives such as organic oxides or sulfur burns off particularly hot and rich in energy.
- a protection against rolling away can be provided. Eyes or the like for attaching lashing straps or the like can also be used. to connect the neutralization body to the object to be destroyed.
- the shape of the opening in the closure cap can be round or square.
- a slot shape or a cross-slot shape is also possible if a desired internal pressure is generated.
- FIG. 2 shows the active mass container from FIG. 1 with a nozzle in a sectional view
- FIG. 3 shows a neutralization body with the active mass container from FIG. 2 in a sectional illustration.
- a pre-assembled active mass container 1 is shown in a sectional view.
- This active mass container 1 holds a pyrotechnic set 2. This is preferably pressed.
- the pyrotechnic sentence 2 is to be implemented in such a way that the required energy is made available.
- An EOD cutting charge is preferred as the pyrotechnic charge 2.
- This can be a thermitic compound with potassium nitrate. The proportion of potassium nitrate should be between 5% to 18% of the pyrotechnic rate 2.
- iron filings or the like can be added to the pyrotechnic charge 2, for example.
- a channel 3 is formed within the active mass container 1.
- the channel 3 is preferably arranged centrally along a longitudinal axis of the active material container 1. This channel 3 can already be taken into account when the pyrotechnic assembly 2 is being produced. In this case, the channel 3 is formed within the pyrotechnic assembly 2, preferably centrally. This channel 3 preferably widens in the bottom area 4 of the active material container 1.
- the active mass container 1 has a recess 6 on the front 5 or on the lid.
- the active mass container 1 is provided with a closure cap 7 on the rear.
- the closure cap 7 is fastened to the active material container 1, for example by means of an O-ring 8 (FIG. 2).
- An opening 12 of the closure cap 7 is spaced apart from the active material container 1.
- a sealing plug for channel 3 is marked with 9. This is attached to or in the channel 3 at the bottom.
- the closure cap 7 for its part is preferably designed in the shape of a nozzle. It accordingly has a nozzle shape at least on the inside. An internal pressure can be set via the nozzle diameter of the nozzle. An angle a between 45 ° and 60 °, at which the nozzle extends towards the opening 12, has proven to be aerodynamically favorable.
- the closure cap 7 preferably also simulates a nozzle shape on the outside.
- the neutralization body 20 shows a complete neutralization body 20.
- the basis of the neutralization body 20 is the active compound container 1 with the pyrotechnic charge 2, the channel 3 and the closure cap 7.
- a stopper 10 is located in the front recess 6 of the active compound container 1. This can be screwed in.
- the neutralizing body 20 has a protective insert 11 which, for example, can also be screwed into the opening 12.
- the stopper 10 and the protective insert 11 provide optimum protection during manufacture, storage or transport. These must be removed for the neutralization body 20 to function. Therefore, handle plugs known as stopper 10 and a known universal protection with an annular disk are preferred as protective insert 11.
- the stopper 10 is removed from the neutralization body 20. Instead of the plug 10, an ignition device (not shown in detail) is used. In addition, the protective insert 11 is removed so that the opening 12 of the neutralization body 20 is open.
- the opening 12 of the neutralization body 20 is aligned with an object to be destroyed (not shown in detail). With these objects it can be ammunition or mines or the like.
- the ignition device When the ignition device is ignited, the hot gases from the ignition charge are passed through channel 3 to pyrotechnic charge 2. These in turn ignite the pyrotechnic charge 2.
- the sealing plug 9 in the channel 3 prevents the gases resulting from the implementation of the pyrotechnic charge 2 from leaving the channel 3 prematurely.
- the sealing plug 9 is destroyed when a predetermined amount of gas and thus a predeterminable amount of energy has built up in the channel 3 of the active material container 1.
- the gases that have now been released flow through the closure cap 7 and, due to the nozzle shape, are bundled in the opening area of the closure cap 7 to form a pyroflame.
- the pyroflame for its part hits the surface of the object from the opening 12 in a targeted manner.
- the pyroflame obtained in this way ensures reliable ignition and implementation of the pyrotechnics in the property.
