Definitions

  • the invention relates to a device for ejecting or launching a weapon from a submerged weapon launcher tube, in particular on board a submarine.
  • a weapon-launching tube is conventionally provided with a front door located in the front frame beyond the resistant front bulkhead of the submarine, which is opened for launching or "hunting" a weapon, and d 'a rear door called "breech".
  • Such devices include, in addition to the weapon launcher tube and an associated system for filling and emptying the weapon launcher tube, a turbopump device driven by a compressed air turbine, which delivers the water taken into an input circuit. of water to a launching box opening into the weapon launcher tube via an annular water inlet door. Compressed air actuates the turbine coupled to a pump external to the resistant shell, which sets in motion inside a cylinder the water in order to bring it into the launching box, thus creating an overpressure with respect to the immersion pressure. This pressure difference is then used after opening the annular inlet door of water to create at the back of the weapon the desired piston effect useful for its ejection.
  • turbopump associated with a weapon launcher tube requires an upstream water inlet integrated in the forward frame of the submarine, which makes the architecture of the forward frame more complex and can be a source of indiscretions .
  • a turbopump is conventionally associated with a group of two or three gun-launching tubes, which reduces the defense capabilities in the event of failure of the turbopump.
  • the water inlet circuit and the launch box of a turbopump are cumbersome and this all the more if the submarine comprises several groups of gun-launching tubes because in this case, several turbopumps and their operating circuits associates are required.
  • turbopumps on submarine by autoclave assembly is complex and involves a significant modification of the device, as well as constraints on the architecture of the front frame.
  • Weapons launching devices are also known from weapons-launching tubes, such as pneumatic refoulers, but they have a larger bulk than that of the turbopumps in the longitudinal direction since they require a longer length of weapons-launcher tube. 400 to 500 mm. Despite their relatively limited performance due to immersion, they have enabled the launch of weapons throughout the submarine submergence field for thirty years. type of device is that they cause interface constraints with the weapon.
  • the object of the invention is to propose a device for ejecting a weapon from a submerged weapon launcher tube, in particular on board a submarine, which does not have the drawbacks of the devices known and above. described.
