Definitions

  • the present invention relates to a method and a device for deploying a filotransmission cable of an underwater vehicle from a launching platform.
  • the technical sector of the invention is the manufacture of a reel of filotransmission cable which must take place from and whatever the speed of the mother platform, which launched the underwater vehicle with which it is desired to maintain a connection transmission through this cable and which must unwind itself at the other end another part of the cable as it progresses.
  • One of the main applications of the invention is its use for launching and wire-guiding a self-propelled underwater torpedo from a mobile platform.
  • connection cable between an uninhabited or manned machine, which one wants to control or with whom one wants to keep communications, and from which one wants to receive information, and its support. or implementation platform, where the communication and / or control instruments are located: in the case of a machine moving at low speed and in a pocket area of the support or of the platform, these cables , which can be relatively bulky, are generally fixed on the machine and take place only from the support which itself can immerse in pendulum an intermediate relay support to facilitate the launching and from which deploys the machine a times down to the desired depth.
  • the unrolled parts then remain stationary relative to the water from a given point of separation, located between the support and the machine: they therefore induce little effort on the machine and / or the support and themselves undergo only a small pulling force in return.
  • these torpedoes have for example a housing located in a specific section of the main body, filled with water and generally located towards the middle or at the rear of this body: the wire is wound in this housing in a circular coil with the outer end fixedly connected to the other parts of the machine and the free inner end passing through a tube connecting said housing to a rear outlet located either on the periphery of the thruster fairing, or in its axis; thus when the torpedo advances, the wire is unwound from the inside of the coil by sliding through this tube by the pulling effect which it undergoes starting from the support which launches said torpedo and then in a second step of the part of the thread already unwound.
  • This device has been known for a long time and is applied to all torpedoes known to date, and has been improved during the achievements either by the quality of the cables used and their storage process, either by the systems of connection with the support or by tube passages in the torpedo: some manufacturers have filed some patent applications on certain improvements such as that of the Swedish company FORENADE FABRIKSVERKEN filed on October 17, 1978 under No. FR. 2.406.801 and describing "improvements made to wire-guided torpedoes" or that of the German company LICENCIA PATENT-VERWALTUNGS GmbH, filed on August 24, 1965 under No. FR. 1,602,868 and relating to a "flexible protective sheath for the control metal wire, capable of being unwound from a building coil and from a wire-controlled torpedo coil to be launched from this building".
  • This sheath is indeed stored on the support, attached to the latter by a fixed end through which is threaded the part of the wire to be unwound from the support and stored itself upstream on a spool: the other end of the sheath is attached to the machine, which for its part carries the other part of the wire as indicated above.
  • this sheath unrolls firstly alone, over a length of about 60 m, then, a fastener between the wire passing inside and this sheath breaks under traction, so that if the support moves on its side, the reel of the wire which it carries can unwind, whereas that located on the machine unwinds from the breaking of the fastener and on request, its own part to follow the progress of it.
  • the two coils then allow the two vehicles, the machine and its support, to move independently of one another, while keeping the connecting wire immobile with respect to the underwater environment.
  • the protective sheath linked to the latter avoids the risk of the wire catching in the superstructures, but this sheath requires internal friction over the entire length of the wire, which unwinds when the support moves. this sheath which thus slows down the speed of the support to avoid an excessive force on the wire which passes inside. This must also be able to resist because of this, even by limiting the speed of movement of the support, to a traction of at least 120 N, while a free unwinding as on the side of the machine, resistance to traction of 40 N is sufficient.
  • the fastener is also of course connected to the wire towards the place where the connection is located between the section of the cable which must resist 120 N and that which must resist 40 N which constitutes a weakness. additional to the point where the above spring effect occurs.
  • the protective sheath must be flexible and resist traction, which increases its cost by the choice of materials such as stainless steel and its manufacture in rigid propeller elements, stapled together. others to make reinforcement: now this sheath is lost like the transmission wire at each launch.
  • this metallic sheath rubbing on the superstructures when it plays its protective role also generates noises which propagate in the underwater environment and which can be annoying depending on the application considered, such as launching torpedoes from submerged carrier submarines as is often used in the military.
  • the problem posed is to be able to protect the wire from connection against any possible aggression which may come from the superstructures of the support, but also from the friction in a sheath or other protective structures, while keeping any freedom of deployment to the parts of this wire, both with respect to the support and with respect to the machine for any movement, even at high speed, of these, said parts of the wire once unwound having to remain stationary relative to the ambient environment.
  • said coil incorporating the part of the section of cable with the lowest resistance is integrated into a structure, on which external fins are mounted, and these are oriented relative to the point of attachment of the section of cable then connecting said structure to the platform, so that according to the given length of this section and the desired distance, the latter is obtained for a given speed of movement of the platform.
  • said fins are arranged in number and in location, so that said structure is kept at the minimum distance from the platform in a vertical plane, itself located at a given minimum distance from the plane. vertical from its launch point on said platform.
  • said section of cable with the highest tensile strength is a carrier transmission cable allowing the towing of said reel by said launching platform, whatever the speed thereof.
  • said coil may also be integral with an electronic interface device between the ends of the cable sections and which ensures any necessary transformation of signals then transmitted each in these sections into according to the characteristics of these.
  • the entire section of cable with the lowest tensile strength is a wire of small diameter made up of at least one optical fiber and having only a breaking load of 5 kg minimum, while the section of cable with the highest resistance may be made of metallic connecting wires.
  • the result is a new method and device for deploying a filotransmission cable of an underwater vehicle from a launch platform.
  • Figure 1 is an overview of the device according to the invention after the launch and deployment of the filotransmission cable.
  • Figure 2 is a side view in partial section of the part of the device according to the invention in the storage position.
  • Figure 3 is a view similar to that of Figure 2 just after the launch of the machine.
  • Figure 1 is a schematic overview of device according to the invention and allowing the application of the method also according to the invention, to allow the deployment of a filotransmission cable between an underwater vehicle 1 shown here in form torpedo from a launch platform 2 shown here as being a part of a submarine having launch tubes 8 of torpedo type from which can be launched the craft or torpedo 1 and the assembly of the filotransmission deployment device as described below.
  • This deployment device consists in a known manner of two sections of cable having different tensile strength characteristics, and of which bare minus the part 31 of the section of the lowest tensile strength in general of the order of 50 N, the free end of which is connected to the machine 1, is stored on a reel 5 carried by it and is unwound behind it as and when of its movement so that the unwound part is immobilized with respect to the ambient medium 6.
  • another part 32 of the lowest tensile strength cable section is itself stored on a coil 7 receiving the other end of this section and which is connected to platform 2 by means of the second strongest tensile strength section 4 which is deployed by a given length L from said platform 2 to maintain said coil 7 at a desired distance d from it this.
  • Said coil 7 can unwind by any means known as possibly the same type of coil 5 as that on board the machine 1, said part 32 of the connecting wire section as and when required, in the event of displacement of the platform 2, so that the entire section 3 of the filotransmission cable proper remains stationary relative to the medium 6, whatever the movements of the machine 1 on the one hand and of its launching platform 2 on the other hand.
  • the two parts 31 and 32 of this same section 3 of cable thus unwinds from a point of origin 0 of displacements corresponding to the position at which the coil 7 and the machine 1 are located, while still being integral with it. one from the other as when they are launched by the support platform 2 and when the length of the cable section 4 has reached the chosen length L.
  • the separation at this point 0 of this coil 7 and of the machine 1 carrying its own coil 5 can be done by any means of the automatic release type or breakage of connection from a given force, and therefore determines this point of origin from which the cable section 3 remains stationary in the medium regardless of the movement of the platform 2, at a given speed V2 and of the vehicle 1 at its launch speed and / or possible self-propulsion V1.
  • the section 4 with the highest tensile strength is therefore preferably and essentially a carrying transmission cable which can be of sufficient section to withstand any stress of towing of said coil 7 by said launching platform 2, even at a high speed V2.
  • this said coil carrying the part 32 of the section of cable of the lowest resistance is integrated into a structure 9, which has external fins 10, oriented relative to the point of attachment of the section of cable 4 then connecting said structure 9 to the platform 2, so that along the given length L of this section and at the desired distance d, the latter is obtained for a given speed V2 of movement of the platform 2.
  • said fins 10 can be arranged in number and in location, so that said structure 9 is maintained on the one hand at the minimum distance from the platform d, and on the other hand in a vertical plane. , itself located at a given minimum distance from the vertical plane of its launch point 8 on said platform 2.
  • Said structure 9 indeed behaves as a depressant as used in trawls which have boards which allow the opening, or in towing fish towed by all types of vessels.
  • said coil 7 is enclosed in the structure 9 which can be a streamlined container, enclosing the entire structure and any device associated with said coil 7, and the dimensions and characteristics of which allow it to be fixed to the rear of said machine 1, as shown in Figures 2 and 3, during storage and its launch from any system 8 adapted for this and located on the platform 2, such as torpedo launch tubes.
  • the structure 9 can be a streamlined container, enclosing the entire structure and any device associated with said coil 7, and the dimensions and characteristics of which allow it to be fixed to the rear of said machine 1, as shown in Figures 2 and 3, during storage and its launch from any system 8 adapted for this and located on the platform 2, such as torpedo launch tubes.
  • the entire section of cable 3 with the lowest tensile strength is a wire of small diameter, which can therefore consist of at least one optical fiber, and having only one load of failure of around 50 N maximum.
  • said coil 7 is integral with an electronic interface device located in said structure 9, between the ends of the cable sections 3 and 4, and ensuring any necessary transformation of transmitted signals. in each of these sections according to the characteristics of these.
  • FIG. 2 is a partial section view of a device according to the invention, in the storage position inside, for example, a torpedo launching tube 8, as shown in FIG. 1, and therefore according to a constant diameter representing the interior of said tube.
  • This assembly partially shown here represents by way of example, the rear part of a torpedo 1 equipped with its propellant 11 and a coil 5 for storing the part of the section of filotransmission cable, on board said torpedo 1, as defined above.
  • This assembly also includes the storage reel 7 for the other part of the section of the filotransmission cable which is then connected by a carrying cable 4 to said launcher support: said cable 4 being stored, for example as shown here, in the form of a reel, inside the launch tube 8.
  • This tube also comprises a launcher 12, which makes it possible to eject said torpedo 1, carrying with it the coil 7 by means of a tube, for example of connection la, inside which passes the wire of the filotransmission cable proper.
