Definitions

  • the invention relates to a high-performance drive with arranged in a sleeve propellant powder and a pyrotechnic igniter for igniting the propellant charge powder, wherein the lighter contains an ignition charge and optionally an amplifier charge, and a method for igniting such a high-performance drive.
  • the ignition of propellant powder used in large-caliber ammunition used today is done mainly by means of a pyrotechnic lighter, which is housed axially in the rear of the ammunition. After triggering by means of an electrical or mechanical pulse, the reaction of the pyrotechnic igniter mixture takes place and glowing particles are brought into the propellant charge powder bed under high pressure, which ignite the propellant charge. Due to the geometry of the propellant charge igniter, the ignition currents flow radially outward through holes in the metal jacket of the igniter. With appropriate design, the flow of particles also has an axial component. However, in most cases the first part of the ignition is limited to the rear part of the powder bed due to the dimensions of the cargo space of modem ammunition.
  • the invention has for its object to improve a high-performance propulsion system according to claim 1 so that the internal ballistic conditions are significantly improved at the ignition and thereby are also compact charge structures with high charge density safely ignite.
  • the propellant charge powder can be lighted specifically at previously selectable points.
  • the number and timing of the ignitions is determined so that even under extreme environmental conditions no adverse internal ballistic conditions (eg negative differential gas pressures) can occur.
  • a temperature sensor for measuring the temperature of the propellant charge powder is arranged in the lighter.
  • the tuning of the ignition is done by the fire control computer, which communicates with the individual igniters via the bus, z. B. the temperature at the individual Anzünd Vietnameseen and then decides according to a predetermined scheme on the number, time order and spatial distribution of the triggering igniters or ignition points.
  • retrievable features of the propellant charge powder are stored in the electronic unit.
  • the lighters are firmly connected to the inside of the sleeve and are embedded in a preferred embodiment in running on the inside of the sleeve webs.
  • the sleeve is formed either fully, partially or incombustible.
  • the bus leads to a central ignition piece, which is preferably embedded in the end cap of the sleeve.
  • the ignition piece contains an ignition distributor and a contact screw.
  • the high-performance drive according to the invention for armor or artillery ammunition is used.
  • lighters which are firmly connected to the inside of the cartridge case and light radially or at other angles in the powder bed.
  • the lighters may be embedded in a plurality of lands extending along the inside of the cartridge so as to prevent damage by propellants of powder charge when the cartridge is shaken.
  • the cartridge case itself may be full, partial or incombustible.
  • the ignition nests are connected via a two- or multi-wire bus with a Anzünd Sharing.
  • each lighter contains a stored address and a temperature sensor. As a result, the temperature in the propellant charge bed can be forwarded to the fire control computer.
  • the memory of the lighter also features of the propellant charge powder can be stored to query and correct the Feuerleitrechners.
  • the lighters can be individually addressed or programmed, e.g. whether or not they trigger during the ignition impulse.
  • This multi-point ignition is particularly suitable for high-performance engines, especially for armor and artillery ammunition.
  • Fig. 1b shows schematically in perspective view a cartridge case 1 with a closure cover 2.
  • the closure lid 2 also stubble sleeve called- deducted from the cartridge case 1.
  • the cartridge case 1 On the inside of the cartridge case 1 three webs 3 are arranged uniformly distributed in the circumferential direction, which extend in the longitudinal direction of the cartridge case 1 over its entire length.
  • the cartridge case 1 In the production of the cartridge, the cartridge case 1 is completely filled with propellant powder, so that the webs 3 protrude into the propellant charge powder.
  • the propellant charge powder In FIG. 1a, the propellant charge powder is not shown for reasons of clarity.
  • the webs are sequentially embedded in individual lighters 9 for the propellant charge powder.
  • the lighter 9 Connected to each other are the lighter 9 via a single or multi-core bus line 4, which leads from the three webs 3 to a Anzünd Federation 11 in the closure cap 2 of the cartridge case 1.
  • a bus line 4 is provided for each web 3.
  • the ignition element 11 consists of an ignition distributor 7 and a contact screw 8. If the cartridge is to be fired, a not shown contact element is placed on the ignition element 11, which with a not shown Feuerleitrechner is electrically connected. As a result, the fire control computer is connected to the individual igniters 9 and can read in and read out data.
  • Fig. 1b shows a section across the cartridge case 1 according to Fig. 1a. It can be seen well the three webs, which are arranged offset by 120 ° to each other and in which the lighter 9 are embedded.
  • Fig. 1c shows the detail A of Fig. 1b shown enlarged with schematically drawn lighter 9.
  • An igniter 9 consists of a Anzündsatz 5 and optionally an amplifier charge 6.
  • Fig. 2 shows a detail similar to Fig. 1c, but with individual details.
  • an electronic unit 10 is arranged in each lighter 9, z. As a chip with integrated circuit or a board with electronic components.
  • the bus line 4 is connected to this electronic unit 10.
  • an ignition element is arranged, which ignites the ignition charge 5 at the ignition, which in turn ignites the booster charge 6.
  • a temperature sensor is arranged in the electronic unit 10 or a temperature sensor is connected to the unit 10.
  • features of the propellant charge powder can be stored in the unit 10.
  • the fire control calculator checks the temperature at the ignition points and determines which igniters 9 are to be lit. or not. The Feuerleitrechner then programmed the lighter 9 or the individual electronic units 10 accordingly. If an ignition pulse is emitted during the ignition, then only the desired igniter 9 are ignited.
