Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a device for incapacitating a localized sea mine by means of a destruction charge brought into its vicinity by a carrier vehicle is known from WO 90/01445.
  • the annihilation charge is intended for the detonation pressure effect from below the sea mine.
  • the device mentioned is intended for combating an anchor mine.
  • An underwater drone maneuvers the device, which is designed as a mine clearing device, onto the anchor rope of the anchor mine.
  • a controllable eyelet device ensures the slidable mounting of the mine clearing device on the anchor rope.
  • the mine clearance device rises up along the anchor rope to the mine.
  • the anchor mine is destroyed by detonating an explosive charge on the mine clearance device.
  • the explosive charge of the anchor mine is laterally offset to guide the anchor rope on the mine clearing device, so that the detonation pressure effect occurs from the side below the anchor mine.
  • Combating a sea bed mine silted up in the ground is not very effective with this mine clearing device.
  • the mine hunting flotilla can verify the actually triggered detonation of the extermination charge carried by the remote-controlled carrier vehicle through underwater listening systems, as well as visually on the basis of the water fountain raised during the detonation - but whether the object (located with a greater or lesser degree of uncertainty than an intact seabed mine) really became inoperable as a result of our own explosion, or at least as a result of severe equipment damage, is very uncertain.
  • the invention has for its object to provide a device of the generic type, which provides partially or entirely in the soft ground seabed mines a much greater probability of destruction than can be achieved with destruction charges that are conventionally close to one located mine on the ground and ignited.
  • At least one blowing nozzle is provided on the underside of the structure of the extermination charge.
  • the extermination charge is brought by means of a remote-controlled carrier vehicle to the location at which a seabed mine was previously identified with sufficient probability, for example by using a mine hunting sonar, as described in DE-OS 32 21 013.
  • the precise localization of the remote control vehicle designed in the manner of an underwater drone is carried out using on-board means, which can also be a sonar, or simply a metal sensor.
  • the annihilation charge is placed close to or above the sea mine, whereupon at least one blowing nozzle oriented downward on the structure of the annihilation charge is activated in order to drive the soil under the annihilation charge laterally in the case of a soft bottom of the water and thereby flush it in. So the extermination charge comes to lie laterally below the sea mine, and from this position the sea mine can be fought particularly reliably with the upward-oriented effect of the extermination charge, especially since the sediment beneath the bottom of the body of water has a performance-enhancing effect in the direction of the overlying mine .
  • an annihilation charge 11 is brought as close as possible to a sea mine 13, which rests on or in the water bottom 14, by means of a carrier vehicle 12.
  • the extermination charge 11 is intended for the warhead 15 of the sea mine 13 detonate or in any case damage the sea mine 13 in terms of its essential functional parts in such a way that it can no longer be detonated by the signature of a passing vehicle, ie no longer represents an effective mine block.
  • the position of the sea mine 13 on the body of water 14 is usually first recorded and measured by mine hunting units, in order to then carry the carrier vehicle 12 - typically an underwater drone - remotely controlled via this position for the actual combat.
  • the carrier vehicle 12 has a sensor system 16, for example a sediment sonar or a metal detector, in order to be able to detect sea mines 13 that have been fully sent in at the bottom of the water 14.
  • the remote control of the carrier vehicle 12 is expediently carried out via a cable 17 in order to transmit the classification and position information present on the command ship to the sensor system 16 at a high data rate and to be able to send current sensor information to be correlated therefrom.
  • the cable remote control has the advantage of greater intrinsic safety because it can reliably prevent the carrier vehicle 12 from being oriented against an escort from the mine hunting flotilla due to inaccuracies in the location specification.
  • the destruction charge 11 is dropped or deposited at the location of the relocalized sea mine 13 above the water bed 14.
  • it is provided according to FIG. 2 to place the carrier vehicle 12 on the water bed 14 and open it after charging the electrical ignition circuits for the destruction charge 11 in such a way that the destruction charge 11 remains exactly in the right position.
  • the carrier vehicle 12 with respect to its drive part 18 (rear area) and with regard to its navigation part 19 (front area), for example, by means of to lift pyrotechnically activated force elements in the longitudinal direction of the vehicle from the destruction charge 11 so that it is then exposed.
  • the carrier vehicle 12 as such is a loss if these structural parts 18, 19 are not equipped with buoyancy chambers 20, from which ballast water is displaced, for example, by means of pyrotechnic reaction gases in order to cause the parts 18, 19 to rise hydrostatically from the body of water 14 so that they then can be salvaged on the water surface for new equipment with a destruction charge 11.
  • At least one blowing nozzle 21 oriented downwards is activated.
  • This can be a water jet effect, but preferably the reaction gas jet of a pyrotechnic incendiary device. If the sea mine 13 rests on a solid surface, the function of the blowing nozzle 21 has no special effect. However, if the sea mine 13 has sunk into compliant subsoil (in particular sand or silt), then this soil 22 is blown away by the nozzle 21 under the deposited destruction charge 11, so that it is washed into the water bed 14 to a certain extent (as illustrated in FIG. 3) .
  • the blowing nozzle 21 In terms of equipment, it is entirely sufficient for the blowing nozzle 21 to be effective over a predetermined period of time, which is given, for example, by the capacity of a fire. Because the dimensions of the annihilation charge 11 are significantly smaller than those of the sea mine 13, it is more than likely that the annihilation charge 11 will have sunk deeper into the bottom of the water 14 than the closely adjacent sea mine 13 itself at the end of the effectiveness of the blowing nozzle 21. With the burning out of the blowing nozzle 21 is therefore then the detonator 23 of the annihilation charge 11 is initiated and the sea mine 13 is thus strained from below by the detonation pressure waves.
  • the pressure wave propagation is bundled in the direction of the still open flushing funnel 24, so that it has an increased performance against the sea mine 13 and disables it by detonation or in any case serious equipment damage. Because of the detonation pressure of the extermination charge 11, which detonation pressure 11 acts against the mine 13 with a performance-enhancing effect from below, this is reliably achieved even when the stretched-cylindrical mine 13 is more or less upright partially sunk into the soil 22 and only partially out of the water bed 14 is a constellation that is often encountered in practice, but which offers too little of an attack surface for the mechanisms of action of the conventional control methods.
