Definitions

  • the invention relates to a gun barrel for a submarine with an ejector with a compact design and the ability to silently eject a weapon.
  • weapon tubes are used to pick up and eject objects. Under a gun barrel, a tube is understood in a first approximate round cross-section.
  • Typical weapon tubes are, for example, torpedo tubes or ejectors for decoys or sonar devices.
  • Objects include according to the invention weapons such as torpedoes, missiles, mines and decoys but also storage containers.
  • Storage containers for the purposes of this invention are storage containers such as these used, for example, in submarines for application by torpedo tubes use. These storage containers are used to transport equipment for example for divers and deploy in case of application, especially under water from a submarine.
  • a weapon in the sense of the invention is in particular a torpedo, a missile, a decoy or a mine.
  • Such weapons are regularly carried by warships, such as corvettes, frigates, destroyers, cruisers or submarines. These weapons are regularly ejected through a gun barrel, although other types of emissions are common.
  • the pressure hull thus the outside of the environment of the submarine.
  • an inner part of the pressure body obvious to understand to understand an outer part of the pressure body lying away and arranged in the direction of the environment.
  • a gun barrel of a submarine differs from other gun barrels in that the barrel connects the interior, within the pressure hull, to the environment, outside the hull.
  • the gun barrel In order to reload a gun barrel of a submarine, the gun barrel must be designed so that this is then part of the pressure hull and thus can fully support the ambient pressure.
  • a gun barrel for ejecting the weapon must be brought to ambient pressure.
  • the interior of the gun barrel must be pressure-tight against the interior of the submarine.
  • the space available in a submarine is usually very low, as unnecessary space creates additional buoyancy and thus leads to a significant increase in other components of the submarine, in particular the ballast devices.
  • a weapon is often ejected by compressed air.
  • a weapon for example a torpedo
  • a weapon can be ejected comparatively quickly and easily.
  • a high acceleration is possible, which is needed to accelerate a comparatively heavy torpedo on the short distance of the gun barrel to its ejection speed.
  • This method is relatively loud. When firing a torpedo this can be accepted in the normal combat situation, since the ejected torpedo already reveals the position of the launch by the comparatively high speed of the screw.
  • weapons tubes that have no system for actively ejecting a weapon.
  • the weapon runs out of such weapons tubes, that is, the weapon leaves the barrel of its own accord and with its own strength.
  • a torpedo can run out of a gun barrel.
  • the object of the invention is to provide a weapon barrel, which is very space-saving together with the ejection device and allows a quiet and fast ejection of a weapon.
  • the gun barrel according to the invention for a submarine with an ejection device has at least a first working cylinder and at least one first pressure accumulator.
  • the at least one first working cylinder is arranged in the interior of the weapon barrel.
  • the at least one first working cylinder has at least one first side of the working cylinder.
  • the first side of the working cylinder is filled with gas, for example with air, nitrogen, helium, argon or a mixture thereof, preferably with nitrogen.

  • the at least one first pressure accumulator has at least one second side of the pressure accumulator. The second side of the accumulator is filled with a liquid.
  • the at least one second side of the pressure accumulator and the at least one second side of the working cylinder are connected to one another via at least one first connection, wherein the first connection has a first valve.
  • the at least one first working cylinder has a working piston, wherein the working piston separates the at least one first side of the working cylinder and the at least one second side of the working cylinder.
  • the working piston is with a coupling device connected, wherein the coupling device is designed for ejecting a weapon from the gun barrel.
  • the ejection device leads to a silent ejection of the weapon.
  • a typical problem with the mechanical ejection of the weapon is usually the stop of the working piston at the end of the working cylinder, which generates a loud noise and thus makes the submarine locatable.
  • the gas in the first side of the working cylinder is compressed during ejection.
  • the rapid ejection is, to a first approximation, the adiabatic compression of an ideal gas, the pressure varying with the remaining volume of the first side of the working cylinder:
  • the pressure initially increases very slowly. Shortly before reaching the end of the working cylinder, the volume of the first side of the working cylinder is very small and the pressure rises very quickly. Thus, it comes just before reaching the stop to a deceleration to a stop without the working piston strikes. There is thus no noise.
  • the system is driven by the pressurized gas on the first side of the pressure accumulator.
  • the first side of the pressure accumulator and the first side of the working cylinder have the same pressure.
  • the at least one first pressure accumulator is arranged in the interior of the weapon barrel.
  • This embodiment is advantageous since all relevant components are arranged in the weapon barrel. If insbesodnere the accumulator outside the gun barrel arranged, as this is common today, so must lead a comparatively large implementation in the barrel. Since the weapon barrel is also part of the pressure hull, large feedthroughs are problematic. However, the smaller the implementation, the greater the pressure losses, the lower the maximum achievable ejection speed of the weapon. Also can be dispensed with an accumulator outside the barrel. In particular, in comparison to the ejection of the weapon with water (by introducing water into the barrel behind the weapon) is only a small Volume in the accumulator needed because only the volume in the cylinder must be filled by the pressurized fluid.
  • the volume of the at least one pressure accumulator is 1.5 to four times as large as the volume of the working cylinder. If the volume is a little more than 1.5 times, in a first approximation, the pressure of the first region of the pressure accumulator is reduced to about 20%; if the volume is about 4 times greater, the pressure is reduced to about 70% of the initial pressure. As a result, the energy used is set from the compressed gas for the ejection.
  • the at least one second side of the pressure accumulator and the at least one second side of the working cylinder are connected to each other via a second connection, wherein the second connection comprises means for actively conveying the liquid.
  • the second connection comprises means for actively conveying the liquid.
  • the means for active promotion are preferably arranged outside the weapon barrel. Since time is not particularly critical here, the diameter of the second connection can be kept small, so that only very small openings through the weapon barrel must be provided in order to be able to arrange the means for active promotion outside.

  • the piston rod has at the opposite end of the working piston a first deflection roller, wherein a first pulling device is deflected around the first deflection roller.
  • the first pulling device is connected to a coupling device.
