Definitions

  • the field of the invention is that of devices and methods for recovering an autonomous underwater vehicle or AUV (acronym for the English expression "Autonomous Underwater Vehicle") from a ship.
  • AUV autonomous Underwater Vehicle
  • the critical steps in the recovery of an autonomous underwater vehicle are the step of creating a link between the ship and the underwater vehicle and the boarding step of the underwater vehicle on board. of the ship.
  • the cable is wound to raise the underwater vehicle aboard the ship, for example, by sliding on an inclined plane.
  • the landing phase is performed by unwinding the cable.
  • the patent US 8,145,369 discloses such a solution comprising a docking device and catching means for connecting the underwater vehicle to the docking device, the docking device comprising a flexible link to ensure a connection with a ship.
  • Another solution of this type comprises a reception device comprising receiving means having a flared shape adapted to receive the front part of the underwater vehicle.
  • This reception device comprises locking means for blocking the front part of the machine in the receiving means and is connected to the vessel via a cable attached to the receiving means on the front of the ship so as to to be able to come and shoot the underwater vehicle from the ship by means of the cable and back up on the boat via an inclined plane.
  • This solution has the disadvantage of not allowing the AUV to continue its mission of imaging the seabed by means of an onboard active sonar once the link is established with the docking device and it is towed by the vessel, the AUV having a tendency to rise towards the surface under the effect of the force exerted by the cable subjected to a hydrodynamic drag force when the ship is moving forward.
  • This solution is not optimal since the AUV has a limited autonomy that does not allow it to ensure a long-term mission.
  • An object of the invention is to overcome the aforementioned drawback.
  • the invention relates to a recovery system for recovering an autonomous underwater vehicle from a ship, the recovery system comprising a docking device comprising a stop on which the nose of the AUV is able to come in support, locking means for securing the underwater vehicle with the stop, a flexible link for providing the interface between the docking device and the ship, the flexible link being arranged so as to that the ship pulls the assembly formed by the docking device and the AUV on the front of the AUV when the latter is secured to the stop.
  • the reception device furthermore comprises stabilization means configured so as to make it possible to control the immersion, that is to say the depth and the attitude, in particular the heel and the attitude of the assembly formed by the device. and the AUV to which he is linked.
  • the size and the positioning of the stabilization means are defined according to the size, the mass and the geometry of the AUV to be recovered so as to be able to control the depth and the attitude of the assembly.
  • the arrangement of the flexible link and the stabilizing means make it possible to prevent, once towed, the AUV from rising towards the surface of the water under the effect of the force exerted by the cable when the ship moves.
  • This arrangement makes it possible to control the depth of the assembly formed by the AUV and the reception device in the water column. It thus makes it possible to maintain this set at a sufficient depth, or a sufficiently low altitude relative to the seabed, so that the AUV can acquire sonar images of the seabed, the stabilizing means acting as a depressant. It also makes it possible to ensure that the onboard sonar receiving antenna on the AUV can receive a reflected signal from the transmitting antenna by controlling its roll, that is to say by stabilizing its cottage.
  • control surfaces of the AUV are not dimensioned to ensure this control.
  • the AUV control surfaces are not sized to overcome the force exerted upward by the traction cable when the AUV is towed. They are only dimensioned to control the depth of the AUV when it is autonomous.
  • the system according to the invention thus makes it possible to make the mission of the AUV as profitable as possible since it can acquire sonar images in areas that it could not reach by being towed by a ship but also once its batteries are unloaded while being towed by the vessel. Moreover, the fact of being able to acquire images of an area while being towed by a ship enables it to make this acquisition more quickly than when it is autonomous.
  • the means for stabilizing the immersion of the reception device make it possible to facilitate the establishment of the link between the AUV and the reception device, in particular when the sea is rough because they allow this operation to be carried out under the surface of the aircraft. the water to a depth less impacted by the sea state. These means also facilitate the recovery of the AUV by means of a ramp.
  • the reception device further comprises a plate arranged in such a way that the plate extends under the belly of the AUV when the nose the AUV bears against the abutment, the locking means also making it possible to secure the AUV with the tray.
  • This system has the advantage of limiting the risk of damage to the AUV during the boarding phase on the ship. It allows to remove the contact between the AUV and the ship during this operation and to offer protection to the AUV (to the body of the craft and to the equipment in protuberance on this body). Indeed, once the AUV is secured to the abutment (and therefore the plate) when pulling on the link from the ship to bring the docking device of the ship, the assembly will come slide on the ship or on an inclined plane of the ship. The plate will interface the AUV with the vessel or the inclined plane and provide a protective surface for protruding equipment on the belly of the underwater vehicle of the type of those represented on the figures 1 a and 1b in cross section and respectively in side view.
  • the AUV has an elongate body having an oblong shape in longitudinal section ( figure 1b ) and a rounded shape in cross-section ( figure 1a ).

  • the equipment protrudes on the body 2 of the AUV 1 on the lower sides of the body 2 in a frame linked to the AUV.
  • This equipment includes, for example, active sonar. They are not protected by the hull delimiting the body 2 of the AUV 1 and are therefore very sensitive to friction and shock that can damage them physically and in terms of performance which leads to distort the subsequent measurements made by these equipment .
  • the system according to the invention makes it possible to impose a constant inclination of the underwater vehicle with respect to the plate around the axis of the underwater vehicle, which leads to avoid shocks and friction of the equipment. in protuberance on the body the AUV with the plate but also with the ship. This characteristic is particularly important during the boarding phase.
  • the AUV was not secured to a plate making the interface between the underwater vehicle and the ship, it would be animated by roll movements that could cause shocks and friction between the protruding equipment and the ship.
  • the plate also provides protection to the AUV when the assembly formed by the AUV and the docking device is animated pitching movements, heave and cavally with respect to the ship during the boarding phase.
  • the plate is secured to the stop.
  • the plate has an elongate shape along an axis called the longitudinal axis of the plate between the stop and a so-called free end of the plate, the stabilizing means for varying the attitude of the plate between an interception position in which the depth the tray increases from the stop to its free end and a home position in which the tray extends substantially to the same depth along its length.

  • the stabilization means are configured so as to control the offset of the assembly formed by the docking device and the underwater vehicle when the latter is secured to the stop.
  • the invention also relates to an underwater assembly comprising the system according to the invention, the plate being arranged to extend over the entire length of a lateral sonar protruding from the body of the machine under -marine.
