Definitions
- Ignition device for ammunition in particular medium-caliber ammunition
- associated method for detonating or self-destructing ammunition in particular medium-caliber ammunition
- the invention relates to an ignition device for ammunition, in particular medium-caliber ammunition, having the features of the preamble of patent claim 1.
- the invention also relates to a method for igniting or self-destructing ammunition, in particular medium-caliber ammunition, comprising the ignition device according to the invention with the features of the preamble of patent claim 14
- Ignition devices also called detonators
- detonators are used to initiate an active charge of various explosive devices such as explosives, bombs, rockets, mines, grenades or cartridge ammunition.
- explosives such as explosives, bombs, rockets, mines, grenades or cartridge ammunition.
- ammunition there are a large number of different types of fuses that are used in different areas of application.
- detonator One type of detonator are proximity detonators, which initiate the explosive charge on approaching the target and which are known, for example, from EP0129679 and US3839963.
- Modern proximity fuses include a variety of components such as antennas, radio equipment, radar transmitters and radar receivers, proximity sensors and detonators and detonator fuses that have to be supplied with electrical energy.
- a proximity fuse for rockets is known from GB1584305, in which the total energy requirement of the components is reduced by using a magnetic proximity sensor.
- this type of application can only be used to detect the approach of a ferromagnetic target.
- magnetic interference can have a negative impact on the performance of the proximity sensor.
- DE10341713 discloses a fuze for spin-stabilized artillery shells, in which part of the energy required is taken from the spin of the projectile by a generator, and the energy store can therefore be dimensioned to be smaller.
- the problem with this approach also appears to be the required speed of 300 to 350/s, which limits the range of use to specific types of ammunition.
- a further problem of the cited prior art is the sequential arrangement of the components, which makes the length of the sensors and/or the detonator dependent on the length of the battery.
- a well-known battery for fuzes is the UA 6215 Army Artillery Fuze Battery manufactured by Thales Cryogenics, which has 6 to 9 cells arranged around a glass ampoule containing an electrolyte. When firing ammunition with a battery of this type, the glass ampoule breaks and the electrolyte it contains activates the surrounding cells.
- a disadvantage of this known type of battery lies in the inadequate utilization of the housing volume, since large areas between the glass ampoule and the battery base are kept free for the distribution of the electrolyte.
- the invention is therefore based on the object of providing an ignition device for ammunition, in particular medium-caliber ammunition, in which the ignition device can be used to provide a sufficient amount of energy and at the same time the available volume in the ignition device can be used particularly efficiently. Furthermore, a method for igniting or self-destructing ammunition, in particular medium-caliber ammunition, is to be improved, including the ignition device.
- the basic principle of the invention is essentially that the battery housing has a cup-shaped recess, the at least one electrical or electronic ignition chain component being at least partially arranged in the cup-shaped recess.
- the battery and the at least one electrical or electronic ignition chain component can be arranged in a particularly short axial section of the ammunition.
- the ignition device has an electric detonator.
- the electric detonator is designed as the first ignition chain component to initiate the explosion of the ammunition's active charge.
- this electric detonator is at least partially arranged in the cup-shaped recess.
- the electric detonator is also known as an EED (Electro Explosive Device). This generally refers to a transmitter for one-off applications that converts electrical energy either into heat and/or mechanical work. Depending on the amount of explosive arranged in the detonator contained, the active charge can be detonated directly or via an interposed amplifier stage. Such an amplifier stage is then also part of a so-called ignition chain as a second ignition chain component. If there are several ignition chain components, they are arranged one after the other to form the ignition chain. In a further embodiment of the ignition device, the ignition device has an electronics unit. The electronics unit has a proximity sensor with sensor electronics and/or a height detector and/or an antenna.
- the electronics unit advantageously has a printed circuit board or circuit board.
- a printed circuit board is also referred to as a circuit board.
- the proximity sensor with the sensor electronics and/or the height detector and/or the antenna is/are arranged on the printed circuit board.
- the printed circuit board has areas for conducting electricity and the proximity sensor with the sensor electronics and/or the height detector and/or the antenna is/are using soldering points and/or press contacts and/or plug contacts and/or adhesive connections and/or Welding connected to the printed circuit board.
- the electronics unit preferably has an ignition capacitor.
- the ignition capacitor is located on the printed circuit board.
- the ignition capacitor can be charged by the battery and the electric detonator can be detonated by the current provided by the ignition capacitor.
- the ignition capacitor is able to provide the necessary energy to detonate the electric detonator very quickly.
- the point in time at which the active charge is ignited can thus be controlled very precisely by means of the ignition device.
- the battery housing has at least one cable guide for accommodating an electrical line.
- the cable routing is designed, for example, as a groove in the battery housing. Such a groove is advantageously aligned in a longitudinal direction of the ammunition. The cable routing minimizes the risk of damage to the electrical line, e.g. when installing the ignition device.
- At least one contact element is advantageously connected to the battery housing and/or the cells, so that energy can be transmitted via the at least one contact element, in particular between the electrical detonator and the electronics unit. The energy can also be transmitted via the at least one contact element between the battery housing and/or the cells and the electronics unit.
- the battery housing can also be used to conduct electricity. In this way, only a particularly small number of additional electrical lines are necessary in order to produce the desired connections.
- Various designs of the contact elements are conceivable.
- the electronics unit is advantageously arranged on a side of the battery facing away from the electric detonator, in particular on an end face of the battery.
- the electric detonator faces a detonator and/or the active charge of the ammunition, the detonator and/or the active charge being able to be detonated by means of the electric detonator.
- a detonator represents a special form of an amplifier stage.
- the ignition device preferably has an ignition housing.
- the fuse housing is located at a tip of the ammunition.
- the battery, the electronics unit and the electric detonator can be mounted together as a structural unit in the fuse housing.
- the electronics unit In the assembled state, in particular, first the electronics unit, then the battery and then the electric detonator are arranged sequentially from a tip to an end of the ignition device.
- a proximity sensor is part of the electronics unit, since the proximity sensor is then located near the tip of the ignition device and thus also near the tip of the ammunition, enabling a particularly precise measurement of the distance to a target using the proximity sensor.
- the fuse housing is located at the bottom of the ammunition.
- the battery and the electric detonator are mountable together as a structural unit in the fuse housing.
- the electronics unit can then in particular be arranged separately in the nose and/or in the sides of the ammunition and connected to the battery and the electric detonator in the base by an electrical conductor. In this way, for example, the use of the ignition device according to the invention with bottom-ignited shaped charge ammunition is made possible.
- the battery has one or more cells.
- the electrolyte is advantageously placed within an ampoule.
- the ampoule is designed to rupture when the ammunition is fired, activating the battery.
- the battery is activated by the electrolyte flowing around the electrodes and the resulting contact between the electrodes and the electrolyte.
- the ampoule preferably has glass and/or a metallic material.
- the object on which the invention is based is also achieved by a method for igniting or self-destructing ammunition, in particular medium-calibre ammunition, comprising the ignition device having the features of patent claim 14 .
- the basic principle of the invention is then essentially that the battery housing has a cup-shaped recess, the at least one electronic ignition chain component being at least partially arranged in the cup-shaped recess.
- the method comprises the following sequential steps: a) Firing/shooting down the ammunition, in particular by electrically and/or mechanically initiating a propellant charge; b) activation of the battery by the launch load; c) initialization of the proximity sensor; d) charging the ignition capacitor using the battery; e) decoupling the battery from the ignition capacitor; f) activating the sensor electronics and the height detector; g) when a target is detected: discharging the ignition capacitor onto the electric detonator to initiate explosion of the active charge; h) as an alternative to step g) if no target is detected: self-destruct by discharging the ignition capacitor onto the electric detonator in order to initiate the explosion of the active charge.
- Step b) also includes in particular the bursting of the ampoule.
- the decoupling of the battery from the ignition capacitor in step e) ensures that in the event of a dud, the battery is no longer coupled in as an energy supply.
- the ignition device can be used particularly advantageously in 35 mm caliber ammunition and in smaller caliber ammunition with proximity fuses. However, its use is not limited to these types of ammunition.
- the application of the ignition device and the associated method is also advantageous in other explosive devices such as rockets, artillery shells, bombs, anti-vehicle mines.
- other types of fuses such as impact fuses or remotely activated fuses could also be used.

- the battery 1 is embedded in an igniter case 5 .
- the fuse housing 5 is in turn connected to a projectile or grenade body 8 , the projectile or grenade body 8 containing an active charge 9 .
- the active charge 9 is also referred to as an explosive charge.
- the Electronics unit 2 is attached directly to a battery housing 12 of battery 1 . This can be done by at least one corresponding connecting element 10 such as a retaining clip, a soldering lug, a snapper, an angle, a clip, a plug contact or the like. Additionally or alternatively, this connecting element 10 can be soldered, welded or otherwise connected to the battery housing 12 and the electronics unit 2 .
- the battery case 12 carries within itself the first element of the ignition chain, namely an electric detonator 4. This electric detonator 4 is embedded in the battery case 12 by an insulating sleeve 11, which is shown in more detail in FIG.
- the battery housing 12 has, like conventional ammunition, a cylindrical outer circumference.
- the battery housing 12 has a first end face, with the connecting element 10 being connected to the battery housing 12 on this first end face.
- the battery housing 12 has a second end face opposite the first end face, with a cup-shaped recess being introduced centrally into this second end face.
- the electric detonator 4 is at least partially, preferably for the most part, arranged within the cup-shaped recess. The electric detonator 4 is thus partially enclosed by the battery 1 .
- the insulating sleeve 11 has a contact 13 , the contact 13 being conductive and making contact with a housing of the electric detonator 4 .
- the contact 13 offers a corresponding attachment point for a first electrical line 6.1.
- the first electrical line 6.1 is soldered, welded, crimped or plugged into the attachment point.
- the first electrical line 6.1 and a second electrical line 6.2 are also generally referred to as wiring in their entirety.
- an insulating sleeve 11 made of electrically non-conductive material is required.
- connection between the contact 13 and the insulating sleeve 11 and the battery housing 12 can be plugged, pressed, screwed, flanged or glued.

- the plug contact 14 designed as a contact disk in FIG.
- a battery pin 7 is contacted via the second electrical line 6.2, it being possible for this second electrical line 6.2 to be routed directly in a cable guide 16 on the periphery of the battery housing 12.
- the entire structure of the ignition device serves to save overall length and to achieve contacting of the electrical detonator 4 in as space-saving a manner as possible.
- Fig. 3 the structure of the plug contact 14 is shown in more detail. It can also be seen how the contacting of the pin 15 of the electric detonator 4 is achieved.
- the battery housing 12 has cable guides 16 on the side, the cable guides 16 being designed as grooves introduced into the battery housing 12 .
- the grooves are aligned in a longitudinal direction of the ammunition.
- the first electrical line 6.1 for connecting the contact 13 to the electronic unit 2 and the second electrical line 6.2 for connecting the battery pin 7 to the electronic unit 2 are arranged in the cable guides 16 on the side. This ensures an electrical connection from one end of the battery 1 to the other.
- the advantage of this structure is that the assembly can be pre-assembled outside of the igniter housing 5 and all the elements included are positioned and aligned. The assembly can then be introduced into the igniter housing 5 as a whole.
- the ignition device can be used to implement a method which comprises the following sequential steps: a) Firing/shooting down the ammunition, in particular by electrically and/or mechanically initiating a propellant charge; b) activation of the battery 1 by the launch load; c) initialization of a proximity sensor; d) charging an ignition capacitor by means of the battery 1; e) decoupling the battery from the ignition capacitor; f) activating sensor electronics and a height detector; g) when a target is detected: discharging the ignition capacitor onto the electric detonator 4 to initiate the explosion of the active charge 9; h) as an alternative to step g) if no target is detected: self-destruct by discharging the ignition capacitor onto the electric detonator 4 in order to initiate the explosion of the active charge 9 .
