Definitions

  • the invention relates to a device for emulating hulls for use in active anti-mine defense in the form of a diving body with buoyancy bodies and diving and trimming cells and for receiving arrangements for generating physical ship signatures, in particular as towing body training.
  • the ship signatures can be simulated individually or in combination with regard to acoustics and magnetics.
  • the problem here is to also simulate the pressure, so that a deception regarding the ship signatures of pressure, acoustics and magnetics of the ignition systems of modern mines is possible.
  • Another problem is to design a carrier that can withstand the high loads that occur in the mines detonating in the immediate vicinity.
  • the object of the invention is to improve the known arrangements and to enable simulation of the ship's signatures for pressure, acoustics and magnetics of surface ships and submarines, while also ensuring high resilience through detonating mines of the diving body.
  • the immersion body is formed by a sleeve made of flexible material in the manner of a hose to form a receptacle with a dimensionally stable bow and stern element, in which Bow area water inlet openings arranged and the rear area of the enclosed water is essentially closed.
  • the casing of the immersion body be arranged in a gatherable manner between the bow and stern elements for changing the length by means of a controllable tensioning cable arrangement.
  • the geometry of the pressure field can be adjusted in a simple manner, and ships of different displacement and length can be simulated.
  • the dimensionally stable bow and / or stern element be designed as a receptacle for operating systems, supply units and simulation devices.
  • the shell receives a spiral winding for generating a magnetic field.
  • iron particles such as small balls, be introduced into the shell to reinforce a magnetic field.
  • the immersion body is connected to floats as buoyancy bodies by means of supporting cables.
  • a trailing cable of the immersion body be designed for energy supply and / or control.
  • the immersion body has an independent energy supply.
  • the rear element of the immersion body has a controllable passage opening for setting the dynamic pressure in the immersion body.
  • a diving body 1 is arranged on support ropes 3 by means of a float 2 and pulled over a trailing cable 4.
  • the immersion body 1 in the form of a cylinder is formed by a dimensionally stable bow element 5 and rear element 6, between which a flexible middle part 7 is arranged.
  • the bow element 5 is designed in the form of a flat head and is equipped with a trim cell 8, towing device 9 and a mid-range noise simulator 10.
  • the mid-range noise simulator 10 simulates the noise spectrum of a ship in the medium frequency range.
  • the front side of the bow element 5 has openings 11 through which the interior of the immersion body 1 is always filled with sea water, which has a pressure difference in relation to the surrounding water in accordance with the dynamic pressure.
  • a displacement volume 12 designed as a device space, which limits the underdrive of the rear element 6 and in which the devices 13 required for controlling the simulation device are arranged.
  • the winch device required to shorten the immersion body 1, consisting of winch 14, tension rope 15 and rope stopper 16 and the compressed gas storage unit 18 provided for blowing on the dive cells 17 and trim cells 8, the rudder system 19 installed as a maneuvering aid and the bass simulator 20, which simulates the noise spectrum of a ship in the lower frequency range, is arranged.
  • the middle part 7 consists of a sleeve 21 made of flexible material, for example rubber with a fabric insert, in which a winding 22 is worked in a spiral over the entire length.
  • the envelope 21 is in economically producible modules divided, which are connected to one another and to the rear element 6 and front element 5 via connecting elements 23.
  • the winding 22 incorporated into the shell 21 is designed in terms of the dimensions and the number of turns so that it generates magnetic fields with the aid of adjustable current strengths, which correspond to a large number of ships to be simulated.
  • the winding 22 also serves to achieve the geometric shape of the flexible sleeve 21, in particular with a small pressure difference (low speed).
  • the diving body 1 is equipped with appropriate devices, such as diving cells 17, trim cells 8, carrying ropes 3 and floats 2.
  • the energy supply and control of the individual functional systems is provided by the towing vehicle via the tensile supply cable 4.
