Definitions

  • the invention relates to an underwater antenna of the genus defined in the preamble of claim 1.
  • Such underwater antennas are useful in certain applications, e.g. in conjunction with a mine search or protection sonar or a sediment sonar for seafloor seismic surveys, subjected to significant shock loads from blast waves generated by detonations.
  • further components and assemblies are included, e.g. Electronic components, such as preamplifiers, transmission transformers, chokes, etc. These components are housed in a housing formed in the housing and mounted on a holder, which in turn is fixed in the housing.
  • a known underwater towed antenna (EP 0944127 A2 ) has a flexible tube made of polyethylene, in which a plurality of gel bodies are lined up one behind the other.
  • hydrophones are molded with electronic components for operating the hydrophones.
  • the elastic gel bodies are introduced into the tube together with oil.
  • the gel bodies absorb oil swelling and fill the tube after the swelling process without blistering.
  • the casting of a gel body takes place in a tubular mold with an inlet nozzle and a riser. Gel is poured into the tube via the inlet nozzle.
  • a gel layer is formed in the mold on which the hydrophones and electronic components are placed.
  • liquid gel is filled until the mold is filled with gel, escaping over the riser in the mold existing air, so that after setting the gel body has no air bubbles.
  • a likewise known submerged towed antenna ( DE 195 18 461 C1 ) has an elastic, tubular casing and a plurality of hydrophones arranged centrally and at a fixed longitudinal distance from each other.
  • the tubular envelope is made of polyethylene with a specific gravity of> 1 gr / cm 3 and completely filled with a hydrophone immediately enclosing, soft gel.
  • a known transducer element, in particular hydrophone, for an underwater antenna has a piezoelectric element with a jacket which covers its side surfaces extending parallel to the polarization direction.
  • the sheath consists of a syntactic foam or an elastic or viscoelastic plastic with gas-filled micro-bubbles, wherein the micro-bubbles are preferably concentrated on the outer surfaces.
  • the transducer elements are provided with a cladding of sound-transparent encapsulation material, eg polyurethane.
  • the invention has for its object to reduce in an underwater antenna of the type described above, the forces acting on impact on the components of the housing of the underwater antenna upon impact of triggered by explosions in the water pressure waves.
  • the underwater antenna according to the invention has the advantage that by filling the receiving space with impedance-matched to water filler impinging on the underwater antenna pressure wave is not reflected at the boundary layer to the hollow receiving space, but passes through the entire housing of the underwater antenna without significant reflections. Since no reflection wave is formed, which is superimposed on the incoming pressure wave, the components are accelerated by the pressure wave much less than in an air-filled receiving space, by about half.
  • the filling on the one hand exerts a mechanical support function for the components and on the other hand prevented by the complete enclosure of the components, that they get into resonance and there is a further increase in the forces acting on the components oscillating force, the so-called. Resonance peaking, comes again would cause a doubling of the acceleration value. Overall, thus occur by the filling of the receiving space to the components lower forces, which lower requirements for the shock resistance of the components and lower demands on the bearing forces for the Fasteners of the components provides. Both reduce the cost of manufacturing the underwater antenna.
  • the filler is a liquid or a gel.
  • a liquid filling facilitates the replacement or repair of components. This also applies to fillings with a gel, if the gel has the property to become fluid when heated.
  • the underwater antenna shown as a constructional embodiment is preferably used for mine detection and is an essential sensor of a mine avoidance system.
  • the antenna has a closed housing 10 with a closed rigid housing 10 which is fixed to the free end of a carrier 12.
  • the carrier 12 is held axially displaceable in the hull of a watercraft, in particular a submarine, so that the antenna can be retracted and extended through an opening in the fuselage bottom. Possibly. the carrier 12 is also designed to be rotatable about its longitudinal axis.
  • the underwater antenna has a so-called.
  • Surface array forming transducer assembly 13 from a plurality of individual, horizontally and vertically spaced from each other arranged transducers 131, which are embedded in an encapsulation 14 made of plastic, eg polyurethane.
  • the transducer assembly 13 is received in the front region of the housing 10 and secured to a housing 10 in the transversely extending mounting plate 15.
  • a receiving space 16 for further components 17 of the antenna is provided in the housing 10.
  • These components 17 are, for example, preamplifiers, transformer transformers, chokes or other electronic components.
  • components 17 are fastened to the mounting plate 15 via suitable fastening pins 18.
  • Fig. 1 only schematically illustrated components 17 are in a structural design in Fig. 2 to see. They each have a double-layer printed circuit board 19 on which the electronic components are mounted and electrically connected to each other. Each circuit board 19 is already over mentioned fastening pins 18 fixed to the mounting plate 15. Attached to the mounting plate 15 connectors 20 establish the electrical connection between the electronic components and the transducers 131 of the transducer assembly 13 ago.
  • the entire receiving space 16 is filled with a filler 21 whose acoustic impedance is approximated to that of the water.
  • a pressure wave which is triggered, for example, by the explosion of a mine, with a pressure amplitude p 0 on the transducer assembly 13, the pressure amplitude p 0 remains when passing through the encapsulation 14, which has an acoustic impedance comparable to the water, approximately obtained and meets the interface between encapsulation 14 and filler 21.
  • ⁇ is the mass density
  • c the speed of sound
  • ⁇ the 1 / e-width
  • the 1 / e width is the time span in which the pressure amplitude p (t) of the pressure wave normalized to the pressure amplitude p 0 has decayed to the value 1 / e.
  • a 1 / e width of ⁇ 1 ⁇ 10 -3 sec
  • a speed of sound c 1500 m / sec
  • the impedance matched filler 21 in the receiving space 16 is not present, but this only air-filled, so would the Pressure wave at the interface between the encapsulation 14 and receiving space 16 is reflected and superimpose the reflection wave of the pressure wave.
  • the pressure amplitude acting on the mounting plate 15 would double, so that twice as high bearing forces would be required to prevent detachment of the components 17 from the mounting plate 15.
  • FIG. Fig. 3 and 4 are the acceleration ratios described above for air-filled receiving space 16 (FIG. Fig. 3 ) and in filled with impedance matched filler 21 receiving space 16 illustrated.
  • the acceleration of the knot A by the filler 21 is considerably reduced. Such a reduction is even greater, considering that when the air-filled receiving space 16 on the mounting plate 15, a resonance increase can occur when 1 / ⁇ the resonant frequency of the storage of the components 17 corresponds.
  • the filler 21 is preferably a liquid, e.g. Oil or gel used that is flowable by heating. With such a filler 21, the receiving space 16 can be emptied for the purpose of repair or replacement of the components 17.
  • a liquid potting material e.g. Polyurethane, which hardens.
