Definitions

  • the invention relates to a device and a method for minimizing the noise generated by a weapon balancing device for watering and aerating weapon barrels in a submarine.
  • Submarines typically have gun barrels from which weapons can be ejected.
  • the main weapon is usually a heavyweight torpedo.
  • other weapons such as missiles or mines, can usually also be ejected.
  • Various types of ejection have been established to eject a weapon.
  • a weapon can be ejected by means of compressed air or pressurized water or by means of a mechanical device.
  • torpedoes in particular can also be self-propelling, ie they leave the weapon barrel under their own power.
  • Each of these types has its advantages and disadvantages.
  • mechanical ejection by means of a linear motor is known from DE 10 2014 017 554 A1.
  • Mechanical ejection with an elastomer is known from EP 3 250 877 B1.
  • Mechanical ejection by means of a rigid chain is known from EP 3 274 646 B1.
  • Pressurized water ejection is beneficial for quickly accelerating a heavy weapon in particular.
  • water is fed under pressure behind the weapon into the weapon barrel and the weapon is thus ejected.
  • EP 3 408 604 B1 discloses a pressurized water ejector with a braking mechanism to avoid noise.
  • weapons in particular torpedoes, can also be ejected, for example, by means of compressed air, be ejected mechanically or be designed to run off automatically.
  • mechanical ejection is preferred for mine ejection.
  • a weapon barrel can therefore also have several options for ejecting the weapon.
  • a weapon barrel can also be used, for example, to eject or pick up divers and/or items of equipment.
  • a weapon balancing device is used to irrigate and aerate a weapon barrel without the overall buoyancy of the submarine changing significantly, since no water is taken in from the environment or released to it. Irrigation involves bringing water from a weapon balance cell into a weapon barrel.
  • the weapon balancing cell is also called the torpedo cell. To do this, air is conveyed into the weapon equalization cell and air from the weapon barrel must be brought inside the submarine. During ventilation, the water is fed back into the weapon equalization cell, for which purpose air is introduced into the weapon barrel and now the air from the weapon equalization cell is fed into the interior of the Submarine is headed.
  • the weapon balancing device serves to guide these air currents.
  • KR 10 2021 0 045 613 A discloses a drainage system for torpedo tubes.
  • a gun barrel An important point when using a gun barrel is that the gun barrel must be able to be watered and drained. When flooding the gun barrel, air must be able to escape from the gun barrel. Likewise, for example, after a weapon has been ejected, the weapon barrel must be drained for reloading. The water is then discharged into the weapons balance cell and the air escaping in the process is channeled into the interior of the submarine.
  • a silencer is known, for example from EP 3 507 191 B1, in which gas and water are separated.
  • a pressurized gas ejection device as used for launching torpedoes from submarines and exhibits a significant drop in gas pressure when the object in the device is accelerated to ejection velocity.
  • This invention controls the pressure of the gas by a pressure regulator interposed between a source of pressurized gas and the tube or holder of the ejector; and the pressure regulator supplies additional gas when the gas volume increases during the ejection process.
  • the pressure is controlled and can be maintained at substantially full pressure for the full ejection process and can be adjusted to compensate for a change in mass of an article to be ejected and changes in ejection resistance, such as water depth and the relative speed at which a Ejection process can be performed.
  • the controlled pressure enables smooth repeated operations of the ejector and also enables repeated operations without waiting for an intermediate pressure reservoir to be restored to a predetermined pressure.
  • a noiseless weapon ejection system is known from DE 10 2016 201 101 B4.
  • the object of the invention is to reduce the noise generated by the gas flowing out of the weapon barrel or the weapon equalization cell.
  • the submarine according to the invention has a weapon barrel.
  • the submarine has a weapons balance cell.
  • the submarine also has a weapon balancing device.
  • water can be fed from the weapon equalization cell into the weapon barrel, and the water from the weapon barrel can also be conveyed back into the weapon equalization cell for draining the weapon barrel.
  • the mass within the pressure hull remains constant, so that there is no change in the buoyancy of the submarine during the process.
  • the weapon barrel and the weapon balancing cell are connected to one another in a water-bearing manner.
  • the weapon balancing device also has a gas expansion device.
  • the gas expansion device is used to expand the gas displaced by the water under pressure, thereby equalizing the pressure inside the submarine and thus releasing the gas into the interior of the submarine.
  • the gas could also be fed in directly, but this would mean that the volume flow is dependent on the pressure and, especially at the beginning at high pressure, would flow out very quickly and therefore very loudly.
  • the gas expansion device has a control device for this purpose, the control device being designed to control the gas flow flowing through the gas expansion device as a function of the pressure of the weapon equalization cell.
  • the control device is preferably designed in such a way that the gas flow is reduced when the pressure in the weapon equalization cell is high and is increased when the pressure in the weapon equalization cell is low. This prevents a lot of gas from escaping quickly and thus loudly at very high pressure and from escaping very slowly at low pressure, thus unnecessarily lengthening the time until the weapon barrel can be used again.
  • the weapon equalization cell and the control device are gas-carrying connected for regulating the gas flow flowing through the gas expansion device as a function of the pressure of the weapon equalization cell.
  • the weapon balancing cell has a pressure measuring device.
  • This pressure gauge is connected to a controller.
  • the control device is also connected to a control motor, the control motor being designed to set the control device for controlling the gas flow flowing through the gas expansion device as a function of the pressure in the weapon balancing cell.
  • control device is electronic and connected to a pressure gauge in the weapon balancing cell.
  • the control device controls a valve depending on the pressure measured in the weapon balancing cell.
  • the regulation takes place as a function of the pressure of the weapon balancing cell in that the gas expansion device has a first gas area and a second gas area.
  • the first gas area and the second gas area are separated from each other. Gas can therefore not get inside the gas expansion device from the first gas area into the second gas area.
  • gas can get from the second gas area into the first gas area via a further component, for example via the weapon equalization cell.
  • the first gas region and the second gas region are separate.
  • the second gas area is connected to the gas expansion device with the weapon balancing cell in a gas-carrying manner.
  • this connection between the gas expansion device and the weapon equalization cell is arranged on the upper side of the weapon equalization cell, so that this connection is preferably in direct contact with the gas in the weapon equalization cell. Even if it is theoretically possible to fill the weapon equalization cell completely with water, it preferably always has at least a small gas space.
  • the second gas area is designed in the form of a cylinder piston. This means that gas flowing in or out of the second gas region can move a piston in the cylinder. Thus, the second gas region is variable in size across the piston.
  • the first gas region has an inlet valve. The inlet valve is mechanically connected to the piston of the second gas region. This results in a simple mechanical coupling, so that the system also remains functional independently of usable electronics.
  • the gas flow flowing through the gas expansion device is regulated in that the inlet valve has a conically expanding opening and in that the inlet valve has a conically shaped closure body.
  • the conical closure body can be inserted into the conically widening opening.
  • the first valve can thus be opened and closed depending on the position of the conical closure body.
  • conical means not only a mathematical cone, but in particular also includes the truncated cone or other corresponding modifications of the mathematical cone in practical use. It is preferably a right cone or right truncated cone.
  • the conical closure body is mechanically connected to the piston of the second gas region, for example via a piston rod.
  • the inlet valve can be connected to the weapon barrel and the weapon balancing cell to carry gas.
  • the inlet valve can be connected via one or more valves to carry gas with the weapon barrel and the weapon equalization cell, so that a connection between the first gas space and the weapon barrel or the first gas space and the weapon equalization cell can be made available.
  • connectable means that there is a gas-carrying connection or that it can be established by a simple switching or arranging process, but this can be opened or closed as desired.
  • the opening of the inlet valve is smaller the higher the pressure is, or the larger the opening is, the lower the pressure is.
  • the advantage of this is that when the pressure is high, the gas cannot flow out too quickly and thus too loudly through the small opening. Simultaneously the opening increases with falling pressure and thus compensates for the falling gas flow due to the falling pressure drop, so that a clear acceleration is achieved at the end of the process, which is not critical in terms of noise, however.
  • an optimum can be achieved between quiet and fast for watering and aerating the weapon barrel.
  • the gun barrel of a submarine is often called a torpedo tube.
  • the term torpedo tube is misleading.
  • the gun barrel is also often used to eject divers or their equipment from a submarine and, if necessary, to pick them up again.
  • the piston of the second gas area has a spring, the spring loading the piston to reduce the size of the second gas area.
  • the spring can be arranged as a compression spring on the side of the piston facing away from the second gas area or as a tension spring within the second gas area.
  • any force-generating element similar to a spring can also be used, for example a compressible material instead of a compression spring or an expandable material (“rubber band”) instead of a tension spring.
  • the effect can also be achieved by means of attractive or repulsive forces, for example magnetically.
  • the inlet valve is connected to a four-way valve to carry gas, the four-way valve being connected to the weapon barrel and the weapon balancing cell.
  • the four-way valve is switched in such a way that in the first position of the valve the inlet valve is connected to the weapon barrel and in the second position to the weapon balancing cell.
  • the fourth connection of the four-way valve is preferably connected to a compressed air supply.
  • a compressed air supply may be a compressed gas reservoir, a compressed gas bottle, a boat-wide compressed air supply system, or the like.
  • the gas expansion device has a separating area for separating water from the gas stream.
  • a separating area can have baffles and/or perforated plates to support the separation.
  • the separating area can also be designed in accordance with EP 3 507 191 B1.
  • a silencer for example according to EP 3 507 191 B1, can be arranged behind the separation area for further separation of gas and water.
  • the gas expansion device has a silencer or is connected to a silencer.
  • the four-way valve is connected to a compressed air supply via a shut-off valve.
  • a compressed air supply may be a compressed gas reservoir, a compressed gas bottle, a boat-wide compressed air supply system, or the like.
  • the ejection device or the weapon barrel can be reliably separated from the compressed air supply by the shut-off valve.
  • the conical closure body cannot completely close the conically widening opening. This can be achieved, for example, via the length of the piston rod.
  • the cone of the cone-shaped opening and/or the cone-shaped closure body has elevations to prevent closure.
  • the elevations can preferably be arranged along the cone surface parallel to the flow and preferably straight.
  • the cross-sectional area of the cylinder piston delimiting the second gas region and the conical shape of the inlet valve coordinated in such a way that the volume flow flowing through the inlet valve is independent of the pressure.
  • the invention relates to a method for low-noise irrigation and ventilation of a weapon barrel in a submarine with a pressure hull.
  • the gas flowing out of the weapon barrel or the weapon balancing cell is directed into the interior of the pressure hull.
  • the flow of gas into the interior of the pressure hull is regulated depending on the pressure in the weapon balancing cell.
  • the gas flow is particularly preferably regulated with a constant volume.
  • the gas flow is regulated by means of a first gas area and a second gas area and an inlet valve in the first gas area, the inlet valve being regulated mechanically by means of a piston of the second gas area.
  • the gas flow is regulated by means of a valve, with the opening range of the valve being changed continuously.
  • the opening area can be achieved by changing the distance between two components.
  • the opening area can be enlarged, for example, by means of a screen or the like. If the opening area is already open to the maximum, it naturally cannot be opened any further, even if the pressure continues to drop.

  • This is done using compressed air, which can be taken from a compressed air supply 150 .
  • the compressed air can be routed either into the weapon barrel 20 or into the weapon balancing cell 30 via a four-way valve 120 . In the case shown in FIG.
  • the shut-off valve 140 is open and the compressed air is routed via the four-way valve 120 into the weapon balancing cell 30.
  • water is pressed out of the weapon equalization cell 30 into the weapon barrel 20 .
  • the air expelled from the gun barrel 20 by the penetrating water enters the gas expansion device 40 via the four-way valve 120 and enters the gas expansion device 40 via the inlet valve 80 and thus enters the first gas region 50.
