Definitions

  • the invention relates to an electroacoustic transducer arrangement for underwater antennas of the type mentioned in the preamble of claim 1.
  • Such electroacoustic transducer arrangements are attached for passive, acoustic location in the frequency range between 1 and 12 kHz on cylindrical or horseshoe-shaped carriers and, in their entirety, form a receiving antenna or receiving base on the carrier, which, depending on the type, has a cylindrical base or a cylindrical hydrophone array (CHA) as well as a horseshoe base or conformal array.
  • Cylinder bases allow localization over a panoramic angle of 360 °
  • horseshoe bases in which the carrier is preferably formed by the bow of the ship itself, localization in a somewhat more restricted sector.
  • the hydrophones of the transducer arrangements or staves are individually attached to the decoupling elements serving to isolate structure-borne noise on a cylindrical steel support and their connecting lines are connected individually to the receiving device as insulated cables.
  • the connection cables of, for example, 96 staves of a cylinder base are combined to form a cable harness and routed to the receiving unit via a pressure-water-tight bushing.
  • PUR polyurethane
  • the invention has for its object to provide a transducer arrangement of the type mentioned, which has a good acoustic forward / reverse ratio and drastically reduces the assembly time for producing an underwater antenna with at least unchanged good acoustic location properties.
  • the construction according to the invention integrates all the acoustically sensitive elements, that is to say the hydrophones and the reflector, of a stave in a complete structural unit, the reproducible position of the reflector and hydrophones required for a good forward / reverse ratio being reproducibly ensured.
  • the complete unit can be attached to the carrier in a few simple steps, with only a single electrical connection having to be plugged in by combining the connecting lines of the hydrophones in a radially symmetrical plug. This and also the fact that the exact position of the reflector and hydrophones is defined with tolerance and does not have to be taken into account during assembly, considerably shortens the assembly time per transducer arrangement or stave.
  • the complete dimensionally stable unit also opens up the possibility of mounting the Staves on a cylindrical support made of glass fiber reinforced plastic (GRP) in the case of the cylinder base, which means that the weight of the underwater antenna can be significantly reduced.
  • GRP glass fiber reinforced plastic
  • the reflector has an acoustically soft plate which extends across all hydrophones and which, in a further embodiment of the invention, forms the acoustically soft spring of a spring mass system.
  • the mass is formed by a metal plate, which rests on the front of the soundproof plate facing the hydrophones.
  • the mass of the metal circuit board and the softness of sound of the plate, which is preferably made of polyurethane foam, are coordinated with one another in such a way that useful sound coming from the front is reflected onto the hydrophones above a predetermined resonance frequency and interference noise coming from behind is shielded.
  • the distance of the hydrophones from the metal plate of the spring mass system is chosen so small that no interfering interference occurs between the incident sound and the useful sound reflected by the reflector on the hydrophones in the entire frequency range relevant for the underwater antenna.
  • a very high forward / reverse ratio of the transducer arrangement is achieved, thus avoiding incorrect bearing.
  • the softness of the spring and the weight of the mass are optimized in such a way that the properties of the spring element are largely retained at a given water pressure dependent on the depth of the transducer arrangement.
  • the depth-dependent requirements are brought into line with the maximum permissible total weight of the underwater antenna.
  • the metal plate is constructed in a sandwich construction from two metal sheets with an intermediate bending wave damping layer, wherein the bending wave damping layer is preferably a foil that is glued to the two metal sheets.
  • a bending wave damping layer is described for example in DE 36 21 318 A1.
  • This sandwich structure of the metal plate suppresses intrinsic resonances of the mass of the reflector, which can be excited by structure-borne noise coupling or the water-borne noise signals, very well suppressed.
  • small spherical ceramics are used as hydrophones, which are used to maintain a tolerance-accurate distance from the reflector on a spacer before casting with the essentially tough-elastic elastomer Plastic is attached, preferably glued, which is held in position on the reflector.
  • the plastic spacer is preferably made from the same material with the same acoustic properties as the hard casting. In this way it is ensured that the distance of the hydrophones from the reflector in each transducer arrangement is precisely and reproducibly maintained.
  • the plug accessible on one end face of the hard casting is integrated into a blind hole molded into the hard casting, which receives the mating plug cooperating with the plug.
  • Plugs and mating plugs are designed as coax plugs for producing a pressure-tight electrical connection, which are plugged onto one another in a watertight manner via a plurality of sealing rings.
  • Such coaxial connectors are known for example from DE 37 14 553 A1.
  • At the bottom of the blind hole at least one radial bore opens from the outside of the hard casting, via which residual water which has penetrated into the blind hole can flow out when the transducer arrangement is removed and thus does not come into contact with the electrical plug contacts when the plug connection is opened and closed.
  • the hard casting has a rod shape with a rectangular or square cross section, the connector for the hydrophones protruding into the blind hole formed in an end face of the hard casting. Bores are provided for attaching the rods, which penetrate the hard casting and the reflector completely. By pushing through the holes Cap screws are used to attach the transducer assemblies to the carrier.
  • the electroacoustic transducer arrangement for an underwater antenna has a total of three hydrophones 10 which, together with a reflector 11 arranged behind them in the direction of sound incidence, are embedded in an acoustically transparent hard casting 20 made of an essentially tough-elastic elastomer which can be processed in the casting process .
  • Polyurethane (PUR) is used as the elastomer.
  • the hydrophones 10 are small spherical ceramics (FIG. 2), which are provided with connecting lines 12 for establishing the electrical connection.
  • the connecting lines 12 of all three hydrophones 10 are routed to a common plug 13 which projects into a blind hole 14 formed on one end face of the hard casting 20.
  • the mating connector cooperating with the connector 13 is designated 15 and is when plugged into the plug 13 from the blind hole 14.
  • the connecting cable 16 leading away from the mating connector 15 serves to connect the three hydrophones 10, which are connected in parallel here, to a receiving device, not shown here.
  • Connector 13 and mating connector 15 are designed as coax connectors.
  • the reflector 11 is designed as a spring-mass system made of a mass and a soundproof spring, the mass being realized by a metal plate 17 and the soundproof spring by a soundproof plate, here an elastic soft material plate 18, which is turned away from the hydrophones 10 Back of the metal board 17 is present.
  • a plate made of polyurethane foam is preferably used as the soft material plate 18, the metal plate 17 is made of aluminum.
  • the metal plate 17 is designed in a sandwich construction and consists of two metal sheets 171 and 172 with an intermediate bending wave damping layer 19. Such a damping layer is described in DE 36 21 318 A1 and can be used here.
  • Layer 19 is preferably designed as a film and glued to the two metal sheets 171, 172.
  • the reflector 11 and plug 13 are inserted into a corresponding mold.
  • the hydrophones 10 are each adhered to a spacer 21 (FIG. 2) to maintain a tolerance-accurate distance from the reflector 11.
  • the spacers 21 are positioned precisely on the reflector 11, specifically on the metal plate 17 thereof, for example by small depressions in the metal plate 17 or else by gluing.
  • the Spacers 21 are preferably made of the same material as the hard casting 20, that is made of polyurethane. After pouring the polyurethane into the mold and curing it, the complete transducer arrangement can be removed from the mold.
  • the hard casting 20 preferably receives a rod shape with a rectangular or square cross-section, on one end of which the blind hole 14 is formed and at the bottom of the blind hole 14 the connector 13 protrudes.
  • at least one, preferably two, diametrical radial bore 28 opening in the blind hole 14 is introduced into the hard casting 20, which is shown in FIG. 2 rotated through 90 ° into the plane of the drawing.
  • two bores 22 (FIG. 1) are provided, which are arranged symmetrically between the hydrophones 10 and completely penetrate the hard casting 20 and the reflector 11.
  • the bore section 222 penetrating the metal plate 17 of the reflector 11 has a substantially smaller diameter than the bore sections 221 and 223, which extend from the front of the hard casting 20 facing away from the carrier to the metal plate 17 of the reflector 10 or on the side facing the carrier Back of the hard casting 20 to the soft material plate 18 and extend through it.
  • These bores 22 each receive head screws, by means of which the rod-shaped transducer arrangement is fastened to the carrier.
  • the head of the cap screws is located directly or via structure-borne sound-absorbing intermediate pieces, e.g. B.
  • the direct system is preferred for reasons of cost in an underwater antenna according to FIG. 3, in which the Transducer assemblies can be screwed onto a GRP cylinder as a carrier.
  • the structure-borne sound-decoupling intermediate pieces must be used for the direct attachment of the rod-shaped transducer arrangements to the bow of the ship to form a conformal array.
  • FIG. 3 shows a perspective view of an underwater antenna which is constructed using a large number of electroacoustic transducer arrangements, so-called staves, as have been described above.
  • the underwater antenna designed as a reception base is designed as a cylinder base, the individual staves being placed on the outside on a cylindrical support 23 made of glass fiber reinforced plastic (GRP) and firmly connected to the support 23 via their bores 22.
  • the individual rod-shaped staves are rotated alternately by 180 ° with respect to one another, so that the plugs 13 of adjacent staves lie once on the upper and once on the lower edge of the carrier 23.
  • the connecting cables 16 of a total of 96 staves are each guided half along the upper and lower edge of the cylindrical support 23 and each combined in a connecting unit 24 or 25.
  • a multiple cable 26 or 27 leads from each connection unit 24 or 25 to the receiving device, not shown here.
