Definitions

  • the invention is in the naval field and relates more specifically to handling systems and lifting mounted on ships, allowing the launching and recovery of marine gear or submarine from these vessels, the gear considered being both towed gear and autonomous gear, the latter then being provided with a temporary link during the launching and recovery phases.
  • solutions generally implementing means that involve the intervention of human operators.
  • a known solution consists in providing means of securing on the the hull of the machine, for example fixing rings, these fixing means being arranged in such a way that the machine can be lifted while keeping a horizontal position.
  • the launching and the recovery can then, for example, be carried out by means of a winch mounted on a movable gantry placed at the rear of the ship, or a crane, the crane or the crane allowing to position the hoist winch above the recovery area.
  • the launch and the lift are carried out vertically which limits the possibilities of collision with the ship during the descent or ascent.
  • the lifting of the machine can be achieved by placing it in a nacelle type device itself having appropriate fixing points.
  • This type of solution is applicable, notably independently, to gear towed by the medium but is however not easily applicable to the case of gear towed from the front, insofar as, for obvious reasons of efficiency, it is desired to perform the towing and handling of the machine from a single cable.
  • Handling by means such as those described above using a single cable proves tricky because it is accompanied for the machine a passage from the vertical position to the horizontal position when setting the water and vice versa during recovery.
  • This handling also requires additional operations whose object is, after lifting the machine and positioning above the deck of the ship, to rest the craft flat on the deck of the ship or more generally on a storage area. These operations themselves usually require the intervention of human operators, intervention which is made more delicate and more dangerous by strong sea.
  • the generally preferred solution is to use a handling cable temporarily hung above the center of gravity of the machine.
  • a solution also used provides a handling based on the establishment of means having an inclined ramp on which the machine slides to reach the surface of the water or to get out and return to the ship.
  • the ramp is generally configured so as to guide the machine in a rectilinear path, which prevents the machine can follow a lateral movement.
  • a ramp is not generally not suitable for use by high seas, lateral movements of the machine may then cause damage to it.
  • the implementation of such means comprises a critical phase which is between the moment when the machine comes into contact with the ramp and that where it is completely placed on it. Indeed, the passage of the machine from the surface of the water to the ramp involves contacting the nose of the machine with the ramp, the entry into contact may occur, in particular agitated sea, with a certain hardness that can cause damage to the machine but also prevent the recovery of it.
  • An object of the invention is to provide means for launching and recovering a marine or underwater craft in the safest possible manner, these means can be implemented fully automatically, without intervention or human supervision.
  • An object of the invention is more particularly to propose means adapted to the handling underwater vehicles towed from the front or underwater gear not having means for vertical lifting, but being temporarily connected to traction means, a cable moved by a winch for example, during launching phases and recovery.
  • the invention relates to a launching system and recovery of a marine or underwater vehicle according to claim 1, said system being intended to be installed on a ship carrying out the storage and transport on submarine vehicle area.
  • the system according to the invention also comprises buoyancy means configured and arranged on the ramp so that the free end of the ramp floats on the surface or near the surface of the water when the ramp is lowered.
  • the bottom of the articulated ramp has an outer face configured to form a fairing whose sectional profiles are defined to minimize the drag and lift forces imposed on the ramp by the movement of the vessel and the vertical dynamic movements caused by waves when its free end is in contact with water.
  • edges of the ramp are configured to ensure, together with the fairing of the lower part of the ramp, the buoyancy of the free end of the ramp.
  • the buoyancy means are constituted by floats fixed on the ramp at its free end.
  • the edges of the ramp are configured to maintain the machine on the ramp and limit roll movements printed on the machine.
  • the system according to the invention further comprises reception and guidance means comprising a reception device configured to receive the end of the machine and remain in contact with the machine during the launching operations and recovery, the host device being driven with the vehicle by the traction means.
  • the traction means comprising a traction cable driven by a winch
  • the receiving device is constituted by a fairlead configured to slide along the ramp and through which the cable passes. traction.
  • the reception device furthermore comprises vertical protection elements on which the wings of the machine rest when its end is engaged in the reception device, the frontal support thus produced making it possible to contribute to the keeping the machine in the axis of the ramp.
  • the receiving and guiding means further comprise motor means configured so as to keep the receiving device in contact with the end of the machine as it progresses on the ramp.
  • system according to the invention further comprises complementary support means for holding the machine in a fixed storage position when the ramp is returned to its raised position; the machine is then stored on the ramp.
  • the device according to the invention thus consists of a recovery system that advantageously makes it possible to limit the relative vertical movements between this system and the underwater vehicle, or marine, while the latter floats on the surface, in particular at the critical moment of the contact between these two entities during the recovery. It allows to put the vehicle into the water automatically from its storage position and then retrieve the machine after use and put it back in its storage position.
  • the limitation of the relative vertical movements is obtained by means of a tilting ramp articulated in its upstream part and which comprises means of buoyancy in its rear mean that allow its free end to float to the surface. Furthermore, the streamlined underside of the ramp advantageously limits the impact of the speed of advance of the ship and the striking effects due to waves on the relative positioning of the rear end of the ramp relative to the surface of the beam. water for different sea conditions and speed with respect to water.
  • the fixed end 111 of the ramp is connected to the carrier leaving at least a degree of rotation about a horizontal axis perpendicular to the main axis of the ramp so that the free end can be raised or lowered at the way of a drawbridge.
  • the end 151 of the craft integral with the traction cable, is inserted inside the element 13 and remains in contact narrowly with the latter, which has the advantageous effect of maintaining the axis of the vehicle in the axis of the ramp 11 during its progression along the latter.
  • the reception and guiding means may also comprise motor means (not present in the example of FIG. figure 1 ) configured such that the receiving element 13 is maintained in contact with the end of the machine 15 as the latter progresses on the ramp 11.
  • motor means act for example by exerting some resistance to the progression of the fairlead towards the fixed end of the ramp.
  • these motor means may for example consist of an auxiliary winch which pulls the reception device 13 (the fairlead) towards the free end 112 of the ramp 11 (downwards), via a cable returned by a pulley located at the free end of the ramp. Adjusting the tension of the auxiliary winch with respect to the tension generated by the towing winch 16 then makes it possible to maintain active maintenance of the contact between the machine 15 and the fairlead 13 during the ascent of the machine 15 along of the ramp 11, without however hindering the ascent.
  • the machine can be secured to the host element when its end is inserted therein. In this case, the action of motor means becomes less necessary.
  • Illustrations 2-a, 2-b and 2-c of the figure 2 illustrate an essential characteristic of the invention.
  • Figure 2-a shows a schematic side view of the ramp 11, in a lowered configuration for which the free end 112 is immersed in water. This configuration corresponds to the implementation of the ramp during the launching operations and recovery of the machine 15.
  • Figure 2-b shows for the same configuration (ramp down), a view of the ramp according to a horizontal section plane passing through the axis ⁇ 2 presented on the side view 2-a.
  • illustration 2-c it shows a view of the ramp according to a vertical section plane passing through the axis ⁇ 1 presented on the side view 2-a and perpendicular to the axis of the ramp 11.
  • the bottom 113 of the articulated ramp 11 has an outer face 21, intended to come into contact with the surface of the water, which forms a fairing whose sectional profile is defined, as shown in the views 2 b and 2-c, so as to minimize, when the free end of the ramp is in contact with the water (lowered ramp) in accordance with the schematic view 2-a, the drag and lift forces caused by the speed of advance of the ship on the one hand and to minimize the knocking effect caused by the waves on the other hand.
  • the profile of the outer face 21 of the bottom 113 of the ramp 11 is defined so as to act in the manner of a breakwater to break the wave front likely to collide with the ramp 11, due to in particular the movement of the ship 10, before they reach the free end 112 of the ramp, and do not cause, at the rhythm of the passage of the waves under the ramp 11, a sudden variation of the vertical position of the free end 112 of the ramp 111 by relative to the surface of the surrounding water.
  • This sudden variation would result in particular, in the absence of any compensation, by an uncontrolled variation of the vertical position of the end 112 of the ramp 11 relative to that of the end 151 of the machine 15, which may cause damage to the latter if it occurs as it approaches the ramp.
  • the outer face 21 of the bottom 113 of the ramp 11 forms a fairing with a sectional section in the form of "V".
  • this face 21 forms a fairing with a sectional profile in the shape of "W”.
  • the device according to the invention makes it possible to safely recover an underwater vehicle, or marine, while the ship in charge of the recovery is advancing with a non-zero speed. by formed sea.
  • the device is designed to be implemented from a moving ship, advantageously allows this vessel to be more manoeuvrable and limits the amplitude of its movements under the action of the movements of the sea. following, the use of a favorable course facing or back to the swell can greatly limit the roll movements.

  • the device according to the invention also has the advantage of being able to be installed on a wide variety of vessels with different tonnages and shapes. It may also, depending on the application considered, include in addition to the essential characteristics described previously, complementary elements allowing for example to facilitate its implementation in the operational context considered.
  • the device according to the invention is for example placed between the two hulls of a catamaran type ship, preferably towards the rear of the ship.
  • the machine 15 considered here is a towed underwater vehicle with wings 151 providing a depressant function.
  • the size and constitution of these fins also makes them relatively fragile.
  • the machine 15 is here towed by means of a towing cable 14, a cable electrotractor for example; wound on a towing winch 16.
