Definitions

  • the invention is directed to a mine with fold-out legs or erecting elements and at least one sensor wire that can be laid from the mine.
  • Such mines are known for example as throwing mines from DE 3 713 424-C1. They are ejected from missiles and brought into the operative position by means of erection elements that only take action when the mine has come to rest on the ground.
  • the invention is also directed to those mines in which the feet spread immediately after being ejected from the missile and which therefore usually already land in the correct operative position.
  • the mines according to the invention are used in particular to combat armored vehicles.
  • Directional mines or ascending mines are particularly suitable for this, since the coverage of the vehicles from above is the lowest.
  • the mines are to be triggered automatically by the armored vehicle to be combated, which is brought about by at least one sensor line installed in the field in connection with an evaluation circuit in the mine.
  • Sensor line is preferably understood to mean an active element, for example an optical fiber cable or a piezo cable.
  • a signal generated in the sensor line is transmitted to the mine via the sensor line.
  • the invention further described below basically also includes a passive sensor line, for example a cord, which transmits tensile stress, as a result of which a sensor on the mine then responds.
  • a passive sensor line for example a cord, which transmits tensile stress, as a result of which a sensor on the mine then responds.
  • a sensor system is less sensitive and more susceptible to faults and is rarely used against vehicles.
  • a mine known from DE 3 713 424-C1 contains an ejectable sensor wire which is thrown out of the mine by spring force.
  • a relatively large amount of space is required for the sensor wire and the ejection device in the upper area of the mine, since the sensor wire must be ejected at an angle of approximately 45 ° to the axis. The laying of the sensor wires in the field is often not sufficient with this type of mine.
  • the invention has for its object to design the mines mentioned so that as little space in the mine is required for the laying device of the sensor wire and a larger laying width of the sensor wires can be achieved.
  • the object is achieved by a mine of the type mentioned at the outset, which is characterized in that it has at least one space-saving sensor wire laying unit which is connected to an aligning device in such a way that the sensor wire laying unit is in a position for the Laying the sensor wire can be brought in a favorable position.
  • a reduction in the space requirement is achieved in that the sensor wire laying unit, which is cuboid or cylindrical in the first approximation, is accommodated in the mine in such a way that the large cuboid axis or cylinder axis is perpendicular to the mine axis.
  • the cylinder axis or the large axis of the cuboid coincides with the starting direction of the sensor wire laying unit, and therefore in the leads according to the invention the sensor wire laying unit must first be brought into an optimal sensor wire laying position, which should be approximately 45 ° to the vertical.
  • an alignment device which either requires its own mechanism or where the already existing folding mechanisms for the feet or the righting elements can be used.
  • the sensor wire laying unit can be attached directly to the legs of a mine. For example, if the legs are spread about 45 ° and the lead lands on their feet, the sensor wire laying unit is also correctly aligned.
  • the sensor wire is wound on a coil former before it is laid and this coil former is moved radially away from the mine by a pyrotechnic or mechanical means of transport.
  • a pyrotechnic or mechanical means of transport With pyrotechnic means of transport, larger laying distances of the sensor wires can be achieved easily and safely. It is particularly favorable if the coil body rotates during the laying process in order to reduce tension peaks in the sensor wire.
  • the sensor wire laying unit can also be used to distribute, in particular, acoustic sensors in a defined manner around the mine outside the mine axis.
  • acoustic sensors are also often used in addition to the sensor wires as triggering signal transmitters, it being important that these sensors have a certain constellation with one another, for example form an equilateral triangle, in order to have a further criterion for the location and evaluation of objects to be combated.
  • Fig. 1 shows a mine laid in the field, which is intended to fight an armored target from above.
  • the mine is usually distributed by an aircraft and has five legs 1 (only three of which are shown in the figure) which fold out during the flight.
  • the mine usually lands in the operative position, as shown in Fig. 1.
  • the drawing shows the two-part structure: the lower part 2 of the lead contains the electronics, the power supply and the opening mechanism for the legs 1.
  • the actual active body 3 can be identified by means of a drive (the outlet nozzles 4 of a rocket engine) rise in height and fight an object from above as soon as the evaluation logic has rated the sensor signals as significant.
  • an active sensor wire 5 generates an electrical or optical signal when it is loaded with a minimum weight.
  • the sensor wires 5 are laid in the field by the sensor wire laying unit 6, which here has a rocket motor as a pyrotechnic means of transport.
  • the sensor wire laying unit 6 is shown in section in FIG. 2.
  • the sensor wire laying units 6 are accommodated in the lower part 2 of the mine during the transport phase (the axis of the sensor wire laying unit 6 is perpendicular to the mine axis). If the legs 1 open by 45 ° during the landing flight, the sensor wire laying unit 6 attached to it has also already reached its optimal position for laying the sensor wire 5.
  • the sensor wire laying units 6 are started with a time delay automatically or by a special radio signal, with a relatively weak rocket motor being able to carry the sensor wire 5 away over a distance of 50 m or more.
  • Fig. 1 is also indicated that on a leg 1 ', for example, two sensor wire laying units 6', 6 'can be attached.
  • more sensor wires 5 ', 5, can be laid than legs 1 are present on the lead, and it is also possible to produce different sensor wire patterns (in particular different widths).
  • the sensor wire laying unit 6 used in FIG. 1 with a rocket motor 7 and a coil former 9 surrounded by a sleeve 8 is shown in section in FIG. 2.
  • the rocket motor 7 has a housing 10, a cover 11, a solid propellant charge 12 with insulating washer 13 and an igniter 14.
  • nozzles 15 which are directed outwards at an angle (the nozzle axes run obliquely to the axis of the sensor wire laying unit 6).
  • the propellant charge 12 burns off, the propellant gases exiting through the nozzles 15 not only cause the coil to accelerate forward (upward in the drawing), but also simultaneously rotate the entire sensor wire laying unit 6 with the coil about its own longitudinal axis.
  • the gases emerging from the nozzles 15 cannot damage the sensor line 5.
  • the unwinding of the sensor wire 5 from the bobbin 9 is supported by the rotation if the winding is matched to the speed and the rotation of the sensor wire laying unit.
  • the rotation also contributes to flight stabilization and the reduction of influences due to inaccurate thrusts of the nozzles 15.
  • the sleeve 8 also limits the sensor wire 5 from being thrown off the bobbin 9 if the rotation should not be optimally coordinated with the development.
  • FIGS. 3 and 4 show another mine, which can again be laid from the air, and which is brought into the operative position only after it has landed by means of hinged erecting elements 22 consisting of a double-legged torsion spring 20 and a support plate 21.
  • hinged erecting elements 22 consisting of a double-legged torsion spring 20 and a support plate 21.
  • pyrotechnic transport device on the sensor wire laying unit is also shown here.
  • the alignment elements 23 are constructed here in a manner very similar to the erection elements 22. When the mine is installed, both the fold-out erection elements 22 and the spring struts 25 forming the alignment device are tied to the mine. There are twice as many erection elements 22 as alignment elements 23, each alignment element 23 being covered by an erection element 22. There is a coupling between the elements 22 and 23 during the unfolding: When a tether band 26 is released, the lead is first erected (the elements 22 are opened by approximately 90 °); only then can they go to the top swing out the edge of the mine rotatably mounted struts 25 by about 45 °.
  • the sensor wire laying unit 24 is attached, which is explained in more detail in FIGS. 5 and 6.
  • the sensor wire laying unit 24 is relatively long and wide, but not very high. It can be accommodated advantageously in the bottom area of the mine. There it is installed so that the smallest dimensions lie in the axial direction of the mine, i.e. its large axis is aligned perpendicular to the mine axis, which inevitably has the consequence that the sensor wire laying unit 24 only has to be inclined by the alignment element 23 if a larger laying distance is to be achieved.
  • FIGS. 5 and 6 Another pyrotechnic means of transport formed by a "projectile-like body” 30 and a “launcher” 31 is shown in FIGS. 5 and 6 (section AA according to FIG. 4, the launcher 31 being inserted into the sensor wire laying unit 24 such that the Direction of arrow 40 points away from the mine).
  • a coil 32 In or on the projectile-like body 30 there is a coil 32 which is surrounded by a cylindrical sleeve 33 which is closed on one side.
  • the sensor wire 34 is wound on the bobbin 32.
  • An additional (not shown) acoustic sensor can be attached to the projectile-like body 30 and is connected to the evaluation logic of the mine via the sensor wire 34.
  • Such acoustic sensors can take over a wake-up function. They can also trigger the mine (in addition to triggering by running over the sensor wires).
  • the piston 35 with a sealing ring 36 is inserted in a tube 37 closed on one side, on the bottom of which a propellant charge 38 with an ignition pill 39 is attached.
  • a propellant charge 38 with an ignition pill 39 is attached.
