Definitions
- the invention is concerned with an ignition device, in particular with an ignition of pyrotechnics.
- the invention also relates to an ammunition comprising this ignition device.
- Irritation bodies which are deployed as a non-lethal measure for disorientation etc., have a similar structure.
- DE 10 2010 052 209 A discloses an irritation body of this type.
- DE 10 2016 111 947 A1 also describes an irritation body which comprises a rocker arm for triggering an effect charge integrated in the irritation body.
- shock tubes are non-electrical detonation initiation systems such as the "Nonei EZ DET 1.4 ß" from Dyno Nobel.
- the shock tube traditionally ignites a detonator.
- the detonator contains a detonative set, e.g. HDX.
- shock tube systems are pre-assembled, ie the ignition unit, cable drum, shock tube and trigger with detonator are assembled and delivered in this way.
- the advantages of the shock tubes are, inter alia, that they have good reliability and a manageable construction and that they are insensitive to electrical or are electromagnetic influences. This property enables a wide range of assemblies and a wide range of uses in the defense sector.
- shock tubes in combination with a detonator or a detonator generates high temperatures and pressure or a detonation wave. Therefore, use is only permitted in specially secured rooms. This prevents the use of current shock-tube systems with detonators as a primer for practice ammunition in the police or military sector for e.g. realistic simulations of access including access blocking.
- shock-tube systems with detonators as an ignition means for, in particular, practice ammunition in police and military areas has so far been excluded due to the disadvantages of the shock-tube systems, although DE 20 2017 102 257 U1 is an ignition device consisting of a mechanical Trigger, a thermo or shock tube of variable length and a detonator for military or police use.
- the tube, trigger and detonator is wrapped around, stored in a protective tube and arranged and designed to be pulled out of the protective tube with the detonator.
- DE 10 2006 007 483 A1 names an ignition hose called a shock tube.
- This ignition hose is constructed in several layers with an inner polymer layer, an outer polymer layer and at least one intermediate layer with tear-resistant reinforcing threads.
- the object of the invention is to demonstrate a variable ignition device which can be replaced in particular for practice ammunition or other non-lethal ammunition.
- the invention is based on the idea of enabling the use of a shock tube in combination with a pyrotechnic.
- a direct ignition from the shock tube to the pyrotechnic charge should take place.
- a detonative implementation is excluded.
- the ignition chain consists of only three energetic elements: primer cap, shock tube and primer mixture.
- the primer is preferably mechanically deformed and ignited. The mechanical action can be taken over, for example, by a firing pin.
- the primer acts on the shock tube. According to the invention, this is vaporized with an explosive and energetic.
- the ignition mixture in turn is ignited by the flame beam from the shock tube.
- the active charge can comprise a light charge, for example a light star, a smoke body, lightning, bang etc.
- the active charge or the pyrotechnic element is ignited by the ignition mixture in order to react.
- the shock tube is preferably integrated in a thin tube or sleeve. With the help of this connecting sleeve, a clamping or non-positive connection of the shock tube is ensured, both on the igniter side on which the primer cap is installed and on the firing side where the pyrotechnic ignition mixture is ignited by the flame jet of the shock tube.
- the shock tube is preferably crimped on both sides airtight and watertight.
- the diameter of the connecting sleeve should be in the range of 2-5 mm.
- a metal is preferred as the material.
- the length and / or shape of the connecting sleeve can also be chosen freely, but should be adapted to the shock tube. The length of the shock tube is also freely selectable.
- Flexible or variable ignition chains and over-ignition paths of different lengths can be set, here by the length and / or shape of the shock tube.
- the connection of various primers / primers and ignition systems, e.g. Rocker arm remains possible.
- Safe firing of the pyrotechnics can also be realized from a distance, and spatial separation of the effect charge (pyrotechnics) and triggering is possible.
- a realistic simulation of access blasting is now offered without the use of safety-critical explosives.
- the proposed ignition using the shock tube system enables extremely rapid ignition transmission of, for example, up to 5000 m / s.
- the shock tube system can be designed in the form of an adapter. So you can react on site to the conditions of use and individually select a adapter in or on the ammunition z. B. screwed, but at least connected to the charge of the ammunition.
- Fig. 2 shows an application.
- the ignition device 100 comprises at least one ignition transformer 1.
- the ignition transmitter 1 is coated with a thin layer of a special explosive (not shown in more detail), for example vaporized.
- This thin layer only has a low explosive effect, i.e. H. minimizes a possible explosive effect.
- the length and / or shape of the ignition transmitter 1 can be freely selected.
- the ignition transformer 1 is arranged between a primer 4 associated with the ignition device 100 and an ignition charge 5.
- the ignition charge 5 serves here to amplify an ignition flame for a subsequent, in particular pyrotechnic, element 6 (FIG. 2).
- the primer 5 can be part of the igniter 100 or an ammunition 20.
- the ignition transformer 1 is preferably at least one shock tube. However, a detonator of the shock tube is not used.
- the ignition chain of the ignition device 100 begins with the ignition of the ignition transmitter 1 via the primer 4.
- the ignition charge 5 is then ignited by means of the ignition transmitter 1.
- the detonative wave of the ignition transmitter 1 is not used, as was previously the case when a shock tube is used, but the flame that forms.
- the ignition charge 5 in turn then initiates the prototechnical element 6, e.g. a light set, a smoke set etc. (Fig. 2) of the ammunition 20.
- the pyrotechnic element 6 can be accommodated in a housing 10 of the ammunition 20. This can be training ammunition, irritation bodies or other non-lethal ammunition.
- the primer 4 can be fixed in a preferred embodiment in the first connecting sleeve 2.
- the ignition transmitter 1 is non-positively fastened with a (first) end 1.1 in the first connecting sleeve 2.
- the ignition transformer 1 is also non-positively fastened on the side opposite the primer 4 in the connecting sleeve 3 with its other (second) end in the latter.
- An airtight and watertight fastening is preferred.
- An airtight and watertight connection can be achieved, for example, by crimping.
- the connecting sleeves 2, 3 can preferably have a diameter of 2-5 mm.
- the second connecting sleeve 3 can be part of the housing 10 in which the active charge or the pyrotechnic element 6 are located.
- the pyrotechnic primer 5 can also be introduced into the housing 10.
- the connecting sleeve 3 can also be screwed onto the housing 10, for example. It is important that a functional interaction between the ignition transmitter 1 and the ignition charge 5 is guaranteed.
- the primer 4 itself can be triggered, for example, by a rocker arm, firing pin or the like, not shown.
- the ignition transmission system or the shock tube system can also be designed as a modular adapter element 30.
- the adapter element 30 can be formed by the primer 4, the ignition transformer 1 and the ignition charge 5.
- the ignition charge 5 does not have to be part of the adapter element 30.
- the connecting sleeves 2, 3 can then complete the adapter element 30.
- the connecting sleeve 3, as already stated, can be part of the ammunition 20.
- adapter elements of different lengths and / or shapes can be created.
- the shape of the adapter parts 30 can be predetermined by the at least one shock tube 1.
- the advantage of such adapter elements 30 is, inter alia, in that these adapter elements 30 are only connected to the ammunition 20 when their intended use is planned or intended. In this way, an adapter element 30 can be selected adapted to the on-site situation, i.e. The length and / or shape is decided according to the application situation.
