Definitions

  • the invention relates to an underwater vehicle carrying a sonar antenna. More specifically, the invention relates to the architecture of this vehicle. It is a powered vehicle advancing advantageously at the front of a surface building.
  • the detection means mounted on the vehicle consist of a sonar antenna, and more particularly of a linear antenna.
  • the detection means are placed under the vehicle, the antenna constituting these means therefore only having a degree of freedom in the horizontal plane.
  • the invention provides an underwater vehicle equipped with propulsion means and detection means and connected by a cable to a surface building, characterized in that it comprises at the front and in prominence a part forming a ball joint 20 which supports an antenna 10 elongated so as to allow the rotation of the antenna in all directions, and by the fact that it has on the front a saucer shape and on the back a notch 1 of shape and depth to allow the movement of the connecting cable 30 in all directions, the point of attachment of the cable being in the hollow 2 of the notch substantially in the plane of the thrusters 50, 51
  • the ball joint 20 comprises a rotation cylinder 24 along the longitudinal axis of the vehicle, a transverse axis of rotation 25, and a vertical axis of rotation not visible in the figure.
  • the antenna 10 is shown in a horizontal position. As is very well known, it includes an alignment of acoustic transducers 21 making it possible to transmit and receive acoustic waves. In this position detection is done in the horizontal plane, that is to say according to the deposit.
  • the antenna can be placed vertically to carry out the detection along the vertical plane, that is to say in elevation, as shown in FIG. 5. This rotation is controlled from the surface building via the cable 30 .
  • the antenna can be turned upside down in a horizontal position to protect the active face of the transducers when the antenna is not working, as shown in Figure 6.
  • the distance D indicated in Figures 1 and 2 is chosen large enough.
  • the antenna is freed from roll and pitch movements.
  • the vehicle is provided with roll and pitch movement sensors (not shown in the figures).
  • the signals provided by these sensors controlling a servo which corrects the position of the antenna in real time.
  • the antenna rotates around the axis 24 to compensate for the roll.
  • the antenna rotates around the vertical axis to compensate for pitching while in the horizontal position the antenna rotates around the axis 25.
  • the movements of the laces are measured, deviations from the heading, and the movements of the antenna are compensated, in the horizontal position along the vertical axis, in the vertical position along the axis 25.
  • the antenna can be placed in a longitudinal position by turning it around the vertical axis. In this case, the operation is done in lateral vision.
  • the vehicle is designed so as to have a notch 1 in the shape of a "V" as is clearly shown in Figures 1 and 6.
  • This notch is completely hollowed out from top to bottom.
  • the so-called "V” shape is not critical; it can approach a "U” without departing from the scope of the invention.
  • the cable is hung in the hollow 2 of this notch, which allows the cable to travel both in the horizontal plane and in the vertical plane. Especially the cable has the possibility of shifting downwards. To ensure good stability, the attachment point is in the plane of the horizontal and vertical thrusters.
  • the vehicle is provided with a single central keel 40 supporting a elevator 41. This ensures good navigation stability while preserving the hydrodynamics.
  • the vehicle comprises two horizontal thrusters 50, vertical propellants 51 symmetrical with respect to the notch 1. It also includes a transverse thruster 52 in the keel visible in FIG. 2 which allows the vehicle to steer at the fixed point in the current.

  1. Tauchfahrzeug, das Antriebsmittel und Detektormittel besitzt und über ein Kabel mit einem an der Oberfläche schwimmenden Schiff verbunden ist, dadurch gekennzeichnet, daß es vorne vorstehend einen Drehkopf (20) aufweist, der eine längliche Antenne (10) trägt, so daß die Antenne in alle Richtungen gedreht werden kann, und daß das Tauchfahrzeug vorne untertassenförmig ist und hinten einen Ausschnitt (1) einer solchen Form und Tiefe besitzt, daß das Verbindungskabel (30) in alle Richtungen ausgelenkt werden kann, wobei der Verankerungspunkt des Kabels sich am Grund (2) des Ausschnitts im wesentlichen in der Ebene der Antriebsorgane (50, 51) befindet.
  2. Tauchfahrzeug nach Anspruch 1, dadurch gekennzeichnet, daß die Antenne drei Arbeitsstellungen, nämlich eine horizontale querliegende, eine horizontale längsliegende und eine vertikale, sowie eine Ruhestellung entsprechend der horizontalen querliegenden Stellung besitzt, aber um 180° nach hinten gedreht ist, so daß die Antenne geschützt wird.
  3. Tauchfahrzeug nach Anspruch 2, dadurch gekennzeichnet, daß die Antenne bezüglich der drei Arbeitsstellungen hinsichtlich der Roll-, Stampf- und Schlingerbewegungen nachgeregelt wird.
