Definitions

  • the invention relates to an underwater vehicle, in particular a submarine, with at least one side antenna arranged on the vehicle body and extending in the longitudinal direction of the vehicle for receiving acoustic signals.
  • each side antenna arranged on port and starboard also called flank array sonar (FAS)
  • FAS flank array sonar
  • Noise sources in the underwater vehicle such as drive motors and the like, generate not insignificant noises which are transmitted via the vehicle body to the hydrophones of the side antennas attached to the vehicle body. Since this so-called structure-borne noise largely covers the useful sound received by the hydrophones as background noise, structure-borne noise decoupling of the hydrophones is essential.
  • the invention is based on the object in a watercraft, in particular a submarine, with the side antenna to construct the latter in such a way and to connect it to the vehicle body that a technically simple attachment of the side antenna to the vehicle body is achieved while maintaining good structure-borne noise decoupling of the individual hydrophones.
  • This constructive training is intended to allow the side antenna to be retrofitted to the vehicle body that has already been completed without further ado and at a reasonable cost.
  • the well-known hydrophone streamer which in its construction z. B. is shown and described in US-A-4,160,229 and has found its first use as a seismic measurement, consists of a hydrophone chain in which the individual hydrophones are coupled between the spacer elements in a completely decoupled manner.
  • the spacer elements and the individual hydrophones are surrounded by a sheath, and the electrical connecting lines to the individual hydrophones are routed as a wire harness inside the sheath.
  • the cover which is closed at the end, is filled with a liquid which, on the one hand, acoustically decouples the individual hydrophones from one another and, on the other hand, is used to make the streamer buoyancy-neutral.
  • Such hydrophone streamers are currently also used in large lengths as tow antennas or towed arrays drawn by submarines in the water.
  • the structure of the side antenna according to the invention and its attachment to the vehicle body ensures very good structure-borne noise decoupling of the individual hydrophones.
  • the side antenna can be easily retrofitted to the vehicle body that has already been manufactured, and at such low retrofitting costs that retrofitting submarines with side antennas is very attractive.
  • An advantageous embodiment of the invention results from claim 2. This measure results in a very simple mounting of the streamer on the vehicle body with good structure-borne noise isolation. This structure-borne noise decoupling is further improved in the exemplary embodiment of the invention according to claim 4 in that the spacer elements of the hydrophone streamer are additionally largely elastically suspended on the holding members fastened to the vehicle body.
  • An advantageous embodiment of the invention also results from claim 5.
  • the coating of the vehicle body in the area of the streamer results in damping of the signals acoustically emitted by the side wall. Such acoustic signal radiation can be triggered both by natural vibrations of the side wall and by reflections of useful signals on the side wall.
  • An advantageous embodiment of the invention results from claim 8.
  • These measures make it possible to significantly increase the distance from the side antenna to the vehicle body and at the same time the maneuverability of the vehicle, for. B. when creating, not to interfere. or to effectively protect the side antennas from damage or destruction during necessary maneuvers of the vehicle.
  • the distance of the side antenna of approx. 60-100 cm from the vehicle body that can be achieved with the specified measures is sufficient to almost completely eliminate the influence of the vehicle body on noise and to ensure a very good S / N ratio of the side antenna.
  • An advantageous embodiment of the invention results from claim 11. This measure folds the side antenna in not only in a protected area on the vehicle body. spent, but at the same time lifted out of the water, so that maintenance or repair of the side antenna is possible without having to dock the watercraft itself.
  • the submarine shown in FIG. 1 as an example of an underwater vehicle has an elongated hull in a known manner. 10 and one of them towering entry tower 11.
  • a side antenna 12 is attached to the hull 10 slightly below the center line, of which only the starboard side antenna can be seen in FIG. 1.
  • the side antenna extends over a substantial part of the longitudinal extent of the hull 10 and is preferably located exclusively in the rectilinearly stretched area of the hull 10.
  • the side antenna 12 which has a length of approximately 30 m, consists of a hydrophone streamer 13 enclosed by an enveloping body 14 (FIG. 2).
  • a hydrophone streamer 13 also called hydrophone drag chain or seismic measuring cable, is known per se.
  • An embodiment of such a hydrophone streamer 13 is described in US-A-4,160,229 or in DE-A-29 41 028.
  • the hydrophone streamer 13 shown here in detail and in section in FIG. 3 is described in DE-A-2719 951 (there FIG. 8), so that the structure of the hydrophone streamer 13 is only briefly explained here for the sake of clarity.
  • the hydrophone streamer 13 has a hose jacket 15 which is supported by shaped pieces 16 at certain intervals. These spacer elements formed by the shaped pieces 16 each consist of two prefabricated plastic molded parts 161, 162 with through openings 17, 18 for two line strands 19, 20, in which the connecting lines leading to hydrophones 21 are combined.
  • the fittings 161, 162 are on two pull cables 22, 23 at certain intervals, for. B. by clamping sleeves 24, and thus securely held against longitudinal displacement.
  • the hydrophones 21 arranged at certain intervals in the hose jacket 15 are each arranged between two shaped pieces 16.
  • the hydrophones 21 (FIG. 4), which are cylindrical in design, are seated in a holder 25 clamped on the pull cables 22, 23.
  • This holder is simply composed of two resilient halves 251, 252, for example made of plastic, the pull cables 22, 23 of which each half-comprehensive end portions are held together by spring clips 26.
  • the middle part of the assembled holder 25 encloses a cylindrical cavity for receiving the hydrophone 21, which is resiliently held therein.
  • the hose jacket 15 is filled with liquid, which ensures good acoustic transmission properties between the hydrophones 21 and the hose jacket 15.
  • the hydrophone streamer 13 is shown only schematically in cross section as a unit. It is held by holding members 27 on the hull 10 at a distance from the latter.
  • the holding members 27 are arranged at a uniform distance from one another over the longitudinal extent of the hydrophone streamer 13, the spacing of the holding members 27 from one another being selected such that the hydrophone streamer 13 is held in the region of its spacing elements 16 (FIG. 3).
  • the holding members 27 are on a foundation 28 connected to the hull 10, for. B. fastened by screwing and wear on their free end faces clamp-like fasteners 29 which encompass the hydrophone streamer 13 around its hose jacket 15. Between each fastener 29 and the hose jacket 15 of the hydrophone streamer 13 is a sound decoupling elastic insert 30 which, for.
  • the B. can be made of plastic or rubber.
  • the hydrophone streamer 13 and the holding members 27 with their fastening elements 29 are covered by the enveloping body 14, which is closed on both end faces and is fastened to fastening tabs 31 connected to the foundation 28.
  • the outer skin of the hull 10 is provided with a sound-absorbing or sound-absorbing coating 32 in the immediate vicinity of the hydrophone streamer 13.
  • the coating 32 expediently also covers the foundation 28.
  • the side antenna 112 which is again designed as a hydrophone streamer 113, is attached to two movable holding arms 133, 134.
  • a traction cable 135 or 136 engages on each end face of the hydrophone streamer 113.
  • the traction cables 135, 136 can be wound up via cable winches, not shown, arranged in the hull 110, so that the hydrophone streamer 113 assumes a largely straight stretch position between the holding arms 133, 134.
  • the holding arms 133, 134 are designed to be movable relative to the hull 110.
  • a drive mechanism 137 (FIG. 6) engages on each holding arm 133, 134, by means of which the holding arm 133 or 134 can be transferred into two different positions.
  • the holding arms 133, 134 are designed as pressure-medium-driven telescopic rods 138 which can be extended and retracted in the horizontal direction.
  • the drive mechanism 137 is formed by a hydraulic cylinder 139 which is connected to a hydraulic system (not shown) via two separate pressure lines 140, 141. At their free end, the telescopic rods 138 each carry a fastening element 129 encompassing the hydrophone streamer 113.
  • the hull 110 consists in a known manner of an inner pressure body 142 and a hull 143 that surrounds the pressure body 142 at a distance.
  • the space 144 between the hull 143 and the pressure body 142 is flooded.
  • the drive mechanism 137 is expediently arranged in the intermediate space 144 and fastened to the hull 142.
  • the holding arms 133, 134 in the form of the telescopic rods 138- pass through recesses 145 in the ship's hull 143.
  • the hydrophone streamer 113 is protected between beads 146, 147, which each surround a recess 145 in the hull 143.
  • the hydrophone streamer 113 assumes a maximum distance from the hull 110.
  • the extension length of the telescopic rods 138 is dimensioned such that the hydrophone streamer 113 is now essentially outside the acoustic near field of sound radiation emanating from the hull 110.
  • both holding positions of the holding arms 133, 134 lie in a horizontal plane 148.
  • the position of this horizontal plane 148 with respect to the hull 110 is such that the hull 110 has its greatest horizontal width dimension here.
  • the hydrophone streamer 213 or 313 is in turn attached to two holding arms which are movable with respect to the hull 210 or 310, of which only the one a holding arm 233 or 333 can be seen.
  • the holding arms - as shown in FIG. 8 for the holding arm 233 - are each held on the hull 243 about a horizontal pivot axis 249 pointing in the longitudinal direction of the ship.
  • the holding arm 233 is pivoted via a pivoting lever 250, which in turn is driven by a hydraulic cylinder 239.
  • FIG. 8 shows the holding arm 233 for the starboard side antenna 212 in its state when it is folded against the hull 210 and the holding arm 233 for the port side antenna 212 in its state when it is folded down from the hull 210.
  • the shape of the holding arms 233 is adapted to the curvature of the ship's hull 243, so that they bear largely positively on the latter.
