Definitions

  • the present invention relates to an underwater vehicle such as a submarine proper, comprising means for launching an underwater vehicle by water thrust.
  • These launching means also known in the state of the art as a torpedo launcher tube or weapon launcher for example, generally comprise an underwater vehicle launcher tube associated with means of ejecting the latter.
  • this pneumatic rammer is placed at the rear of the vehicle launcher tube and actually includes a telescopic piston comprising several stages, which pushes the weapon by mechanical contact at the rear of it to eject this weapon from the tube.
  • This pneumatic rammer is then associated, for example, with pneumatic means for its deployment and hydraulic means for its retraction.
  • a device similar to such a rammer can also be used for water-thrust vehicle launching systems.
  • the rear part of the weapon launcher tube is connected to a water distribution tank, itself connected to a water tube, in which a piston is placed to push water into the rear part of the tube in order to push and eject the vehicle.
  • the piston is then set in motion by the ram.
  • the discharge device is a multi-stage telescopic piston, connected to a compressed air source via a launch valve.
  • the discharge device is a pneumatic piston connected to a pressurized gas tank.
  • the document EP A 3 106 825 also describes a device according to the preamble of claim 1.
  • the aim of the invention is therefore to solve these problems.
  • the invention relates to an underwater vehicle comprising means for launching an underwater vehicle by water thrust, comprising a vehicle launch tube having a front part and a rear part and the rear part of which is connected to a water distribution tank, itself connected to a water tube in which is placed a piston for discharging water into the rear part of the tube in order to push and eject the vehicle, the piston is associated with means forming a linear electric actuator for moving the latter, characterized in that the means forming a linear electric actuator comprise at least two telescopic actuator stages deployable one beyond the other.
  • a vehicle launcher tube such as for example a weapon launcher or torpedo launcher tube of an underwater vehicle such as a submarine itself, using a pneumatic rammer.
  • the vehicle launcher tube is designated by the general reference 1, the vehicle to be launched by the general reference 2 and the rammer by the general reference 3.
  • this rammer is a telescopic piston comprising several stages which eject the weapon by pushing at the rear of it into the tube.
  • This piston is for example associated with pneumatic and hydraulic services as described previously.
  • FIG. 3 illustrates the principle of ejection using a water thrust.
  • the vehicle to be launched is designated by the general reference 5 and this vehicle is placed in a vehicle launcher tube designated by the general reference 6.
  • This tube 6 has a front part and a rear part.
  • the rear part of the tube 6 is connected to a water distribution tank designated by the general reference 7, itself connected to a water tube 8, in which is placed a piston 9 for discharging water into the rear part of the tube 6 in order to push and eject the vehicle.
  • this piston is for example a telescopic piston comprising several stages and which can then be, as described previously, associated with pneumatic and hydraulic services.
  • the piston be associated with means forming a linear electric actuator for moving it.
  • the linear electric actuator is designated by the general reference 10.
  • actuator stages are for example designated by the general references 11 and 12 in these figures.
  • the piston is designated by the general reference 13 on this figure 4 .
  • each stage of the electric actuator can be associated with its own electrical supply means such as the means designated by the general references 14 and 15 in these figures.
  • control means can, for example, use chopper-shaped means, making it possible to modulate the power supply to the actuator stages and therefore the speed and force of launching the underwater vehicle according to different parameters such as, for example, the immersion or the speed of movement of the underwater vehicle carrier, the type of launch desired for the vehicle, etc.
  • Such linear electric actuator means can then be integrated as illustrated in the figures 5 , 6 , 7 And 8 , in a water-thrust launching system of an underwater vehicle from an underwater craft such as a submarine itself.
  • the means forming the linear electric actuator are always designated by the general reference 10 and the piston by the general reference 13.
  • the piston 13 can be placed in a water tube designated by the general reference 20, connected to a water distribution tank 21, itself connected to the rear part of one or more vehicle launch tubes of the underwater vehicle, like the tubes designated by the general references 22 and 23 in these figures.
  • a side door for example 24 and 25, or other means then makes it possible to isolate or on the contrary to connect the weapon launcher tube corresponding to the tank 21, in order to allow the launching of an underwater vehicle such as for example a torpedo or other, designated by the references 26 and 27 in these figures, from this launch tube.
  • linear electric actuator means 10 when activated, they deploy and push the piston 13 into the water tube 20, which forces a corresponding volume of water into the rear part of the vehicle launcher tube via the reservoir 21, and which makes it possible to eject the vehicle from the corresponding tube.
