Definitions

  • the invention relates to a watercraft with a shaped charge.
  • Such watercraft are regularly used to clear objects, especially mines, such as in the FR2779514 A1 described.
  • a mine is usually cleared by the explosives inside the mine being detonated by a charge from the outside.
  • a shaped charge is usually used for this purpose. It is important here, however, that the explosives used in a mine itself can be difficult to ignite and only the actual detonator contains highly explosive material. It is therefore necessary to achieve a high energy input into the explosives of the mine in a volume. For this reason, shaped charges are usually used to detonate the explosives in a mine.
  • the object of the invention is to provide a watercraft with which a mine can be safely cleared whose shell surrounding the explosive is not directly accessible.
  • the watercraft according to the invention with a first hollow charge has a second hollow charge, which is arranged behind the first hollow charge in the direction of action of the first hollow charge, the direction of action of the first hollow charge and the direction of action of the second hollow charge running towards a common target point.
  • the direction of action of the first hollow charge and the direction of action of the second hollow charge preferably run along a common line in the direction of the target point, ie they are coaxial.
  • the aim and effect of this arrangement is that initially the first shaped charge is ignited.
  • the first hollow charge is arranged in front of the second hollow charge. This generates a plasma lance, which causes the water placed between the watercraft and a mine to be vaporized. If necessary, this first plasma lance of the first shaped charge penetrates a first obstacle, for example a first wall of a double-walled mine, an ammunition box or the like.
  • the second shaped charge is ignited shortly thereafter, before the bubble created by the evaporation collapses again.
  • the second plasma lance created by the ignition of the second shaped charge can now reach the mine with considerably less weakening.
  • the second hollow charge can be designed and/or arranged in such a way that the second plasma lance is particularly narrow and therefore particularly fast. Under water, this would be particularly weakened at a greater distance, but this is prevented by the first plasma lance. Thus, the energy introduced into the mine can be maximized and the clearing success can be ensured.
  • At least one of the two shaped charges is movably arranged.
  • the first hollow charge and the second hollow charge are movably arranged, the distance between the first hollow charge and the second hollow charge being constant. Due to the mobility, an adjustment to a variable distance between watercraft and mine is possible.
  • the distance between the first shaped charge and the second shaped charge is selected to be large enough for the second plasma lance to be as focused and narrow as possible. Increasing the distance would therefore no longer have a positive effect. A shortening would lead to the fact that the focusing decreases and thus the energy input into the mine may be weakened.
  • the watercraft also has a distance sensor and evaluation and control electronics.
  • the distance sensor is designed to detect the distance between the watercraft and an object arranged in front of the watercraft.
  • the plasma lance must bridge this distance. It is therefore necessary to be able to determine this distance in order to be able to adjust the shaped charges accordingly in order to achieve an optimal effect.
  • the evaluation and control electronics are designed to process the distance between the watercraft and the object arranged in front of the watercraft, which is detected by the distance sensor.
  • the evaluation and control electronics are designed to move at least one of the two shaped charges as a function of the detected distance.
  • at least one of the two shaped charges is moved by the evaluation and control electronics with the aid of a motor which is controlled by the evaluation and control electronics and at least one of the two shaped charges, preferably both shaped charges together, moves.
  • the distance often cannot be set to a predetermined value under water, for example due to obstacles or currents, so it has proven advantageous to determine the actual distance and then adjust the position of at least one of the two shaped charges to the distance.
  • the direction of action of the first hollow charge and the direction of action of the second hollow charge run parallel.
  • the direction of action of the first hollow charge and the direction of action of the second hollow charge are arranged in the longitudinal direction of the watercraft. This enables a slim design.
  • a first gas space is arranged between the first hollow charge and the hull of the watercraft and a second gas space is arranged between the first hollow charge and the second hollow charge.
  • the length of the first gas space in the direction of action of the first hollow charge is less than the length of the second gas space in the direction of action of the second hollow charge.
  • the direction of action of the first hollow charge and the direction of action of the second hollow charge are not arranged parallel to one another.
  • the first gas space which is arranged upstream of the first hollow charge in the direction of action, should be chosen so short that the resulting plasma lance is wide enough for the direction of action of the second hollow charge to be within the opening angle of the plasma lance of the first hollow charge.
  • Advantages of this embodiment are, on the one hand, that the second hollow charge does not have to penetrate the rear wall of the first hollow charge and is therefore not weakened, and on the other hand a shorter design can be realized.
  • the disadvantage is that the first shaped charge generates a comparatively wide plasma lance and therefore has to evaporate a comparatively larger amount of water. Penetration can also be more difficult with a double-walled mine.
  • the first hollow charge has a first igniter and the second hollow charge has a second igniter.
  • the first igniter and the second igniter are connected to an igniter.
  • the ignition device has a delay device, the delay device causing the second igniter to be ignited later in time.
  • the delay device is also considered part of the igniter when the delay device forms part of the connection between the central core of the igniter and the second igniter.
  • the connection between the center core of the igniter and the second igniter may be longer than the connection between the center core of the igniter and the first igniter.
  • the first gas chamber arranged in front of the first hollow charge is shorter in the effective direction of the first hollow charge than the second gas chamber arranged in front of the second hollow charge in the effective direction of the second shaped charge. This ensures that the plasma lance of the first hollow charge is less focused than the plasma lance of the second hollow charge.
  • the watercraft 10 is shown in a schematic cross section.
  • the watercraft 10 has a battery 50, a motor 60 and a propeller 70 for propulsion.
  • the watercraft 10 can also have multiple motors 60 and propellers 70 .
  • a first hollow charge 21 and a second hollow charge 22 are arranged in the watercraft 10 and are aligned with the direction of action in the longitudinal direction of the watercraft and in the direction of travel of the watercraft 10 . It can be seen that the first gas space located between the first hollow charge 21 and the shell 40 is shorter than the second gas space, which is arranged between the second hollow charge 22 and the first hollow charge 21 . As a result, the second plasma jet of the second plasma charge 22 is more focused.
  • the watercraft 10 has an ignition device 100 for igniting the first hollow charge 21 and the second hollow charge 22 .
  • the ignition device 100 is arranged such that the central core of the ignition device 100 has a longer connection to the second shaped charge 22 than to the connection to the first shaped charge 21, so that the connection from the central core of the ignition device to the second shaped charge 22 functions as a delay device.
  • the watercraft 10 has a sonar 90 to determine the distance from the watercraft 10 to a mine.
  • This in 2 Watercraft 10 shown also has a threaded rod 30 with which the first hollow charge 21 and the second hollow charge 22 can be moved together. As a result, the widening of the plasma jet of the first hollow charge 21 can be changed. Due to the constant distance between the first hollow charge 21 and the second hollow charge 22, however, the shape of the second plasma jet remains unchanged.
