Definitions

  • the invention relates to a vehicle in a monohull form for clearing sea mines, which has its own, remotely controllable movement drive and means for triggering remote detonators of the sea mines, in particular means including an electromagnetic core for generating an electromagnetic field.
  • Fields of this type have little in common with the original signatures of large cargo and warships (so-called target ship signatures), because those original signatures have fewer steep flanks of the field components, non-sinusoidal profiles and generally several zero crossings, which is the case with the dipole-like signature of the known mine clearance vehicle only applies to the less important field component in the x direction (direction of travel).
  • the components of those original signatures also have an overall greater spread with the same absolute amplitude.
  • the invention was therefore based on the object of developing a mine clearing vehicle of the type mentioned in such a way that in particular the magnetic field generated by it can be more closely approximated than before to the original signatures of ships which are significant for the attack by mines, for example to the Signatures of larger merchant or warships.
  • this object is achieved in that at least one of the two end exit ends of the electromagnetic core, which essentially extends in the direction of the longitudinal axis of the vehicle, is inclined downwards with respect to the vertical.
  • the electromagnetic core is formed by the outer skin of the vehicle.
  • the means for generating the magnetic field are known electromagnetic coils, which are located in a depression in the outer skin of the vehicle. This depression is closed with an amagnetic cover aligned with the outer skin.
  • the outlet ends of the electromagnetic core are designed as pole shoes, in particular, therefore, by a shape that promotes the directed exit of the field lines.
  • These pole pieces can have the shape of hemispheres that are inclined into the water.
  • the longitudinal axis of the electromagnetic core is inclined at a predetermined angle with respect to the horizontal longitudinal axis of the vehicle and that both longitudinal axes lie in a common vertical plane.
  • a less space-consuming variant of this which promotes the desired goal is that the electromagnetic core is bent in a V-shape in its side view, such that the longitudinal axes of the legs of the V-shaped electromagnetic core are inclined downwards relative to the horizontal longitudinal axis of the vehicle, and that all longitudinal axes lie in a common vertical plane.
  • the electromagnetic core is essentially in the form of a half cylinder and its obliquely extending front end ends are produced by a cut through the half cylinder, the respective means of which point obliquely downwards in the direction of travel of the vehicle and with the longitudinal axis of the vehicle in a common vertical direction Level lies.
  • the measures according to the invention reproduce the above-mentioned original signatures of certain large ships more clearly than was previously possible, with the consequence that greater clearance successes than previously can also be expected in cases of mine closures which can be achieved using particularly intelligent mines.
  • the progress of clearing is further increased if the vehicle is equipped with a functional unit consisting of anodes arranged on the vehicle outer skin in the water area, an active protective anode also arranged on the vehicle outer skin in the water area and a controllable generator for applying a voltage to the Anodes exist and / or if a functional unit is provided, which consists of the transmitting part with associated antenna and power supply of at least one sonar device for radiating higher-frequency sound into the water and / or when using a functional unit, which generates a coil arranged on the deck of the vehicle for generating of an electric field.
  • a functional unit consisting of anodes arranged on the vehicle outer skin in the water area, an active protective anode also arranged on the vehicle outer skin in the water area and a controllable generator for applying a voltage to the Anodes exist and / or if a functional unit is provided, which consists of the transmitting part with associated antenna and power supply of at least one sonar device for radiating higher-frequency sound into the water and
  • the mine clearing vehicle shown by way of example and schematically in FIG. 4 has a fuselage 10 which has the cross section recognizable in FIG. 2 in all exemplary embodiments.
  • the fuselage 10 has the shape of a half cylinder 12, which is closed in the region of its largest diameter by means of a plate 14.
  • the half cylinder 12 forms the outer skin of the mine clearance vehicle and forms, together with the plate 14 and the plates or pole shoes sealing the sealing front and rear, as described below, a rigid and highly shock-resistant pressure body 16, which in itself can be reinforced by transverse bulkheads, not shown and to which, as can be seen in FIG. 1, a bow 18 and a stern 20 are welded for the production of a boat shape.
  • the pressure body 16 can be provided on its lower side opposite the plate 14 with a material reinforcement 22 which increases the strength and improves the stability of the clearing vehicle.
  • the pressure hull 16, fore and aft ship 18, 20 and any frames and transverse bulkheads of the pressure hull in the exemplary embodiment consist of ferritic shipbuilding steel (mild steel).
  • the body 10 At locations spaced apart in the longitudinal direction of the body 10, as shown in FIG. 3, it is provided with depressions 30, in each of which a plurality of electromagnetic coils 32, 34, 36, 38 are arranged. As shown in FIG. 3, the individual magnetic coils are accommodated in individual chambers which are formed by the two outer side walls of the depression 30 and by webs 39, 40, 42 parallel to them. The radial outside of the solenoids are closed by means of an amagnetic cover 44, which lies in the plane of the outer skin of the fuselage 10.
  • the region of the fuselage 10 which has the depression 30 is, in the exemplary embodiment according to FIG. 3, a separately manufactured part which is welded to the fuselage 10 by means of weld seams 46, 48. 3 that the pressure body 16 is stiffened in the region of the depression 30, but also outside of it, by means of a plurality of frames 50.
  • An essential part of the invention for the optimal replication of the target ship signatures is that at least one, but possibly both, front end ends 60, 62 of the described electromagnetic core is or are inclined downwards with respect to the vertical.
  • Fig. 1 it is indicated very schematically that the drawn, inclined arrangement of the outlet ends 60, 62 leads to an increase in the magnetic field below the fuselage 10 and to a weakening above the fuselage.
  • the use of the outer skin of the vehicle as an electromagnetic core in conjunction with the inclined arrangement of the outlet ends not only leads to an intensification of the magnetic field in the water, but also to a field course-like field course in the field directions x indicated in FIG. 2 (longitudinal axis ), y (horizontal transverse axis) and z (vertical).
  • the target is further optimized by the generation of alternating magnetic alternating fields, such as those generated by the corresponding ones
  • the magnetic coils 32-38 can be supplied using currents of different curve shape, polarity and pulse duration.
  • the electromagnetic core can also be closed off by specially designed pole shoes.
  • the use of hemispherical pole pieces 70, 72 is indicated in FIG. 1 by dotted lines and is illustrated in FIGS. 5 and 6 by the schematic illustration. It goes without saying that when the pole shoes 70, 72 according to FIG. 1 are used, the outlet ends 60, 62 shown there are omitted, so that the fuselage 10 then has the hemispherical configuration shown in FIGS. 5 and 6 at least at one end.
  • FIG. 9 shows two variants of pole shoes which are further modified.
  • This pole piece 80 is basically a half cylinder with a cylinder axis 81, which results in the plan view shown in FIG. 10.
  • the half-cylinder of the pole piece 80 is extended, as shown in FIG. 9, in the upper region beyond the cylinder axis 81 so that it can be connected to the essentially semi-cylindrical pressure body 16 and protrudes somewhat downward beyond the underside of the fuselage.
  • the right end of the fuselage 10 in FIG. 9 largely corresponds to the left end; however, the pole piece 82 there, whose cylinder axis 83 corresponds to that of the left pole piece 80, is flattened on its underside, so that the pole piece 82 forms a rectilinear continuation of the underside of the fuselage on its underside, while its semi-cylindrical end face corresponds to that of the pole piece 80.
  • the fuselage 10 of the clearing vehicle which is preferably made of non-magnetic steel or another non-magnetizable material.
  • the structure has a deck house 88, which at that time carried an antenna 90, which is required for remote control of the vehicle.
  • zinc anodes 92 and an active protective anode 94 made of precious metal are attached to the outer skin of the hull 10 within the water, to which a controllable generator 96 is assigned under the vehicle's deck is.
  • Anodes, generator, control for this as well as the associated wiring represent a functional unit.
  • Another functional unit is provided for the optional simulation of hydroacoustic fields, in particular in accordance with the active sonar area of conventional mine-hunting vehicles.
  • This functional unit has a sound transmitter with associated antenna and power supply, which preferably radiates the higher-frequency sound from mine-hunting vehicles into the water.
  • This functional unit is symbolized in FIG. 4 by a transmitting hydrophone 98 in the area of the fuselage 10.
  • the vehicle according to the invention as shown in FIG. 4 has an air coil 100 as a further functional unit on deck and further components, not shown in more detail below the deck of the vehicle, in particular a sine wave generator with a downstream power amplifier, which is connected to air coil 100 in order to prevent the magnetic stray field from To simulate AC consumers on board target ships.
