Definitions

  • the invention relates to a submunition according to the preamble of claim 1.
  • Such a submunition in functional connection with its ignition device, is usually equipped with a complete safety device that works autonomously within the respective submunition, which only arms the ammunition depending on the presence of certain environmental criteria (such as reaching a lurking position or free flight after leaving the Carrier) causes.
  • the invention has for its object to reduce the outlay on equipment for the secure focusing of submunition and thereby open up greater functional reliability as well as less expensive options for functional testing and for the replacement of essential components.
  • the apron releasing criterion can also be relocated to the security device in the carrier itself, that is to say the submunition can be relieved to that extent.
  • the submunition equipped according to the invention is insensitive to mechanical environmental disturbances, because it no longer contains a moving part and in particular no mechanically displaceable securing part. Their structure is no longer weakened, since the safety releasing environmental criteria should only be introduced into the carrier itself, but not into its submunition, for example, no more stylus pens or wind turbine generator slides that would have to emerge from the submunition shell at the submunition required are.
  • Each submunition 11 can equally be launching ammunition with a detonator (see, for example, DE-OS 33 17 376), specifically launched ammunition with a proximity or detonator (see, for example, DE-OS 33 29 700), or detonator ammunition see, for example, US Pat. No. 4,587,902) or steering ammunition (see, for example, the MLRS III system or US Pat. No. 4,522,356).
  • a detonator see, for example, DE-OS 33 17 376
  • specifically launched ammunition with a proximity or detonator see, for example, DE-OS 33 29 700
  • detonator ammunition see, for example, US Pat. No. 4,587,902
  • steering ammunition see, for example, the MLRS III system or US Pat. No. 4,522,356
  • Such submunitions 11 can be brought into the start (ejection or launch) position, for example, by means of unmanned missiles (drones, ranged weapons dispensers, projectiles or missiles) or by means of launching devices which are in wait position, it being in principle irrelevant whether the carrier 12 is equipped with only one or with several submunitions 11 to be activated simultaneously or in stages; in principle can also a manned carrier 11 (for example, an aircraft or a submersible) can be provided if a suitable danger of apron security in the issued submunition 11 precludes a carrier hazard.
  • a manned carrier 11 for example, an aircraft or a submersible
  • a single energy source 13 e.g. in the form of a battery which can be activated thermally or by environmental wine flows such as sea water
  • the safety device 14 is also present only once in the carrier 12, for all submunitions 11 that can be brought together by means of the carrier 12.
  • Each submunition 11 held ready for firing or launching in the carrier 12 is only equipped with an ignition device 15, comprising an electrical charge store 16 (the so-called ignition capacitor) and a mechanical or electrical trigger element 17 (for example an electronically controllable switch such as a thyristor) in series with one Secondary explosives detonator 18.
  • the memory 16 is loaded, if necessary via a converter 22 for current or voltage adjustment, via a tear-off bridge 23 between the carrier 12 and the respective submunition 11, which is separated if there is then a (not shown in the drawing) Control unit, the respective ejection device 24 for launching or starting the submunitions 11 from its carrier 12 is initiated.
  • the implementation example sketched in FIG. 2 preferably relates to an application according to the aforementioned DE-OS 33 29 700, in which only a single submunition 11 is provided per carrier 12.
  • a environmental sensor 21 is provided with a scanner 21.1 (for detecting the leaving of a worker tube with which the carrier 12 and its submunition 11 were brought) and a pressure membrane 21.2 (which only responds to a sufficient water depth after it has sunk); instead, or in addition, sensors 21 acting in a different way, such as a touchdown sensor (not taken into account in the drawing), can be provided, which responds when a lurking position is reached on the water bed.
  • the information provided by the sensors 21 can be transmitted mechanically (e.g. by shifting the linkage) or electrically (e.g. as a voltage level), which is processed in mechanical, mechanical-electrical or electrical converters 25 to unlocking information 26 suitable for influencing the securing device 14.
  • each sensor 21 is assigned an (electrical or mechanical) switch 27 in the safety device 14, which functionally implement an AND operation, for example, as shown, are connected in series. At least one of the switches 27 is actuated by the unlocking information 26 not directly, but via a delay element 28 for apron security.
  • This can be operated from the central electrical energy source 13; or it is equipped with its own energy source (not taken into account in the drawing), for example with a spring accumulator if it is implemented as a mechanical clockwork.
  • the further switch 27 is also activated after the apron protection delay time period has expired, the power circuit from the energy source 13 is closed via the converter 22 and the tear-off bridge 23, and in the ignition device 15 the memory 16 loaded. Now the ejection device 24 can be initiated and the bridge 23 can be torn open when the submunition 11 is lifted out of the holder tube 29 of the carrier 12, because the electrical ignition energy is available in the submunition 11 that has now started, ie the submunition 11 is armed.
  • the warhead detonator 20 responds (for example due to target approach or target impact) and the trigger element 17 is thus switched through, the energy is discharged from the memory 16 into the secondary explosive primer 18, via which - without the need for a detonator which has to be pivoted mechanically in line beforehand - the Battle Charge 19 is initiated.
  • the bridges 23 can be ohmic connections (plug contact, tear wire) or other coupling elements (e.g. optronic or inductive couplings).
