Definitions

  • the invention relates to a system for a shipment of a warhead in a target area according to the features indicated in the preamble of claim 1.
  • Methods of making the mine so manageable that it can be picked up and blown up in a safe place are to apply it a quick-setting foam to secure the igniter or by cooling with liquid helium to block the trigger mechanism.
  • a neutralization of a mine from a safe distance with shelling can lead to damage to the mine, which then no longer permits the approach of a deminerator.
  • the shelling of buried mines is basically out of the question. Even if the mine position is optically marked, the bombardment angle of a vehicle is so unfavorable that in many cases the penetration length in the earth region is too great.
  • the system is designed to allow soldiers with armored vehicles to evacuate recognized mines that are overt or covertly laid;
  • the system must allow the safe neutralization of mines from a distance of 10 - 50 m from the vehicle;
  • the neutralization must be done with high reliability (greater than 95%). It is desirable that the mine does not trigger by the neutralization process;
  • mines All types of mines (smart mines, dump mines, AT mines, AP mines, off-route mines adw, open or buried under the earth's surface) must be neutralized;
  • the system must be designed as a retrofit kit for vehicles and must not affect the vehicle's signature.
  • the vehicle must be in its original state after dismantling the set-up kit;
  • the system must have a high degree of automation in order to relieve the crew of the operation to a great extent;
  • the system must be able to operate on mines or markers visually recognized by the crew, as well as on positions known only by their coordinates;
  • the system should be able to precisely combat enemy positions in the near range so that secondary effects are largely avoided;
  • the system should be usable under all weather and climatic conditions.
  • the basic idea of the method according to the invention is to ignite a fragmentation warhead precisely above the visible mine or, if the mine is not visible below the surface of the earth, above its position, which is either optically marked and / or known as a coordinate.
  • the triggering of the fragmentation warhead causes each mine to be destroyed up to 30 cm below the earth's surface by the action of splinters.
  • the splinter charge contains a splitter density of approx. 0.2 splitter / cm 2 .
  • the fragmentation warhead reaches this fragment density in a circular area of about one meter in diameter.
  • the mine to be destroyed must therefore be within this circle.
  • the mechanism of neutralization is based on mechanically destroying mines by the action of splinters so that they are no longer dangerous.
  • the advantage of this method is that regardless of the size, the design, the ignition mechanism and the laying method (on or below the earth's surface) of the mine is given a high neutralization probability (even against smart mines).
  • the combination of a high-precision mechanical throwing system and a trajectory correction device ensures that the fragmentation warhead precisely above the mine position to effect and thus a high splinter density can be achieved.
  • the trajectory correction by microreaction engines is based on a proven technique that allows extremely simple implementations. With only three microreaction engines on the perimeter of the projectile, a trajectory correction can be achieved once, which brings about the decisive improvement in accuracy.
  • the timing for neutralization is minimal. After detecting the mine position, the neutralization takes place after approx. 10 seconds.
  • the throwing system is perfectly suited for a device-technical realization as a set-up kit.
  • the modules to be adapted only insignificantly change the signature of the vehicle.
  • the throwing system according to the invention makes it possible to realize a set-up kit consisting of the partial areas of throwing system 20 with straightening device 21, laser illuminator 7 and fragmentation warhead 3.
  • Figures 1 and 2 illustrate the throwing system 20 with straightening device 21 for precise shipment of the fragmentation warhead 3.
  • the straightening device 21 allows alignment of the throwing system 20 in azimuth 22 in a range of about 0 to 180 degrees and elevation 23 in a range of approx 60 to 80 degrees.
  • a transport position with 0 degrees is provided.
  • the throwing system 20 can preferably be designed as a spring-throw system, which enables significantly lower scattering of the nominal trajectory compared to pyrotechnic transfer mechanisms.
  • the principle is to stretch springs 1 by means of electric motors 2 so far that upon release of the springs 1, the fragmentation warhead 3 a precisely Preselected initial speed.
  • the force / path profile of the springs 1, which corresponds to this energy can be measured to control the clamping operation by electric motors 2 precisely via force elements or current sensors 4 in the power supply of the electric motors 2. This also influences by temperature and fatigue in the springs 2 can be largely compensated. Since a gas-tight leadership of the fragmentation warhead 3 deleted, the fragmentation warhead 3 z. B. in a cup 5, which is accelerated by the springs 1 via a play-free roller guide 6, are ejected with low Abgang scattering.
  • the laser illuminator 7 shown in FIG. 3 can emit two laser beams 8, 9 independently of one another in freely positionable azimuth and elevation, wherein the laser illuminator 7 is positioned on a vehicle 19.
  • the first laser beam 8 is used to illuminate a mine 10 or a surface position under which the mine 10 is located.
  • the laser beam 8 can be guided by the vehicle crew by manually directing a target mark on the detected mine 10 or be automatically directed via a control unit, not shown. For this automatic control then the exact position of the mine and the exact position and direction of the vehicle 19 are required.
  • the second laser beam 9 has the shape of a fan. Elevation and azimuth angles are automatically determined with respect to the spatial position of the illumination laser beam 8.
  • the azimuth angle of the center line of the fan corresponds to the azimuth angle of the illumination laser 8
  • the elevation angle is greater than the elevation angle of the illumination laser 8 by such a value, so that the beam fan 9 at a preselectable distance 28, which is for example 2 - 4 m, above the illumination position 29 of the mine 10 runs.
  • This laser beam 9 is coded.
  • the fragmentation warhead 3 consists of the following components: A warhead body 11, a fragmentation charge 12, a arranged on the front side of the fragmentation warhead 3 laser position detector 13, which determines the position of the laser light spot 29 of the illumination laser 8, a laser detector 14 with decoder for Detection of the coded laser fan 9, three micro reaction engines 15 with ignition device, which are mounted offset at the periphery of the warhead by 120 degrees, and a control and evaluation unit 16, which causes the control of the laser position detector 13, the laser detector 14, the micro reaction engines 15, as well as the ignition of the warhead.
  • the throwing system works as follows:
  • the electronics and ignition device of the warhead 3 is activated by the throwing process. Approximately 3 m above the ground 24, the warhead 3 dives through the laser fan 9. This event is detected by the laser detector 14 with decoder. Thereby, the laser position detector 13 is turned on at the front side of the warhead 3, which measures the direction of the impact point 25 to the illumination point 29 of the mine 10. The direction is only determined as a sector. The number of sectors is determined by the number of microreaction engines 15. With three microreaction engines 15 equally distributed around the circumference 17, a total of six displacements 18 offset by 60 degrees each can be achieved by firing one or two engines 15. Thus, a resolution of the search range in six 60-degree directional segments is required if one or two microreaction engines 15 are fired depending on the segment.
  • the laser position detector 13 determines whether the trajectory 27 opens into the spot 29 of the illumination laser 8 or the trajectory 27 has a tray 26. Given a tray 26, the angle is measured and the associated one or two engines 15 ignited. This causes a correction of the trajectory 27 in the direction of the illumination spot 10. Since the height of the laser fan 9 above the earth's surface, as well as the velocity of the warhead is known, after a certain time in which the correction of the trajectory is completed, the triggering of the fragmentation warhead 3 can be made about 1 m above the ground. The splinters, not shown, are thus ejected downward in an approximate uniform distribution at a speed of about 800 m / s.
  • the triggering level, the discharge characteristic and the number of splinters are selected so that a splitter density of 0.2 splitter / cm 2 is achieved in a circle of about one meter in diameter.
  • the kinetic energy of the splinters is sufficient to safely destroy the mines after penetrating 30 cm of soil.
