Definitions
- the invention relates to a cartridge with a propellant charge sleeve containing a charge and an electrothermal igniter.
- a cartridge is known in which the igniter consists of several in the longitudinal direction the cartridge extends axially symmetrically arranged ignition channels, wherein each ignition channel comprises a powder tube, which on its inner surface with an electrically conductive layer is provided. If the respective conductive layer becomes Ignition of the charge connected to an energy supply system, so it should suddenly evaporate, and inside the corresponding powder tube is an arc plasma channel generated, through which the further flow of electricity takes place. This is energy with high performance emitted to the environment via radiation transport mechanisms, causing it to rapid ignition of the propellant tubes and their fragmentation occurs. The burning fragments of the propellant tubes as well as the released arc radiation then cause the propellant powder to ignite quickly and evenly.
- the present invention has for its object a cartridge of the aforementioned Specify the way in which a uniform and symmetrical lighting in the Cargo space of the corresponding weapon is possible without the need for additional energy supply systems required are.
- the invention is essentially based on the idea of decoupling the arcs in that instead of a uniform, electrically conductive layer in each powder tube is made up of lozenges, rectangles, circles or Oval existing, flatly arranged conductive structure in or outside on each powder tube is arranged, which has the function of decoupling resistors electrically.
- decoupling resistors electrically.
- the electrically conductive layer can be applied directly to the inner or outer surface of each Powder tube are applied. But it can also be a film pad on the inner or outer surface of the powder tube may be provided, on which the electrical conductive layer is applied.
- the film can be made from a commercially available Plastic, preferably made of polyester or polyethylene.
- the evaporated Structure is preferably made of aluminum or copper.
- the several parallel, preferably three, series connections interconnected decoupling resistors interconnected decoupling resistors.
- the length of the ignition channels can be 50 to 400 mm, preferably 200 to 300 mm.
- the electrically conductive layer is arranged on the inner surface of the powder tube, adjoins the inside conductive layer directly on another powder tube or powder rod. This can the loading density in the cartridge can be increased even further.
- Fig. 1 is a large-caliber cartridge (e.g. for firing from an armored weapon) referred to, which is connected to an energy supply system 2 for ignition.
- the corresponding Gun in which the cartridge 1 is located has been used for reasons of clarity not shown.
- the cartridge 1 comprises a sleeve 4 filled with a propellant charge 3 from a combustible Material and a bottom of the propellant charge sleeve 4, made of metal existing sleeve base 5.
- a high-voltage electrode which is electrically insulated from it 6 arranged with a metal disk 7 acting as a current distributor connected is.
- each of the ignition channels 9 comprises a powder tube 10, which on its inner surface with an electrical made of copper conductive layer 11 is provided.
- the layer 11 is on the metal disc 7 facing side with this electrically connected and consists of three parallel Series connections 12-14 diamond-shaped areas 15 (Fig.3).
- the electrically conductive layers 11 In the area of the sleeve cover 16 of the propellant charge sleeve 4 are the electrically conductive layers 11 with an in 1 only schematically indicated annular contact part 17, which in turn contacts the inner wall of the weapon, not shown, which is at ground potential.
- a switch 18 of the energy supply system 2 is closed (Fig.1) and a series of charged capacitors 19 of the power supply system 2 e.g. discharge suddenly at a voltage of up to 40 kV.
- the one that occurs Discharge current leads to an electrical explosion of the connecting bridges 20 (FIG. 3) between the individual diamonds 15.
- Arcs 21 form at these points (Fig.4) by the decoupling resistors 15, which through the diamond-shaped areas are formed, are decoupled from each other. If the current continues to flow erode more and more parts of the diamond-shaped areas 15 so that the arcs 21st become longer and longer (Fig. 5).
- the powder tubes 10 are ignited by the arcs 21 and suddenly torn apart.
- the flying fragments of the powder tubes 10 and The released arc radiation then causes a quick and even ignition the propellant charge 3 located in the propellant charge sleeve 4, which together then implemented with the combustible propellant charge sleeve 4.
- FIG. 6 shows a further exemplary embodiment of the invention, in which the 22nd designated ignition channel in addition to the first powder tube 10 with arranged on the inside electrically conductive layer 11 (e.g. with a diamond-shaped structure) on the inside Layer 11 comprises directly adjacent powder rod 23.
- the 22nd designated ignition channel in addition to the first powder tube 10 with arranged on the inside electrically conductive layer 11 (e.g. with a diamond-shaped structure) on the inside Layer 11 comprises directly adjacent powder rod 23.
- the powder rod can be replaced by another powder tube. It also has to six ignition channels are not necessarily used. With small calibers e.g. three ignition channels arranged symmetrically in the cargo space are sufficient.
- the electrically conductive areas which the decoupling resistors define, not necessarily be diamond-shaped. Others are also conceivable Shapes of a polygon or a round geometry (circle, oval etc.), if between these areas are conductive bridges, which with a corresponding current flow break up explosively.
- the decoupling resistors are of this type shaped that there are different layer thicknesses in the different areas of the respective rhombus, rectangle, circle or oval.
- the different Metal thicknesses also define the properties of the decoupling resistors and can also be used to determine certain resistance values of the network structure adjust.
- Corresponding exemplary embodiments can be found in FIGS. 7-9.
- there 24 are a substrate (plastic carrier film), 11 the electrically conductive layer, with 15 the area defining the respective resistance (e.g. diamond-shaped) and with 20 denotes the respective connecting bridge.
