Definitions

  • the invention relates to an overall system for moving a rubber dinghy for special forces, which is to be launched from a submerged submarine.
  • the focus here is on minimizing the probability of detection during settling.
  • this problem differs fundamentally from the deployment of rescue facilities, such as life rafts. Rather, when deploying a liferaft, it makes sense to locate it quickly and easily in terms of rescuing the crew. Furthermore, it is even useful to be able to subsequently locate the submarine in order to be able to rescue other crew members, for example with a rescue submarine, if necessary.
  • a deployment system for a life raft from a submarine is known from EP 2 138 395 A1.
  • a system for stowing and deploying a life raft is known from DE 60 2005 00 194 T2.
  • An unmanned underwater vehicle and a device for connecting an optical fiber cable to an unmanned underwater vehicle are known from DE 10 2009 053 742 A1.
  • the object of the invention is to minimize the risk by minimizing the time for detection.
  • the submarine according to the invention has a device for concealed deployment of a rubber dinghy. This makes it possible not only to release divers undetected while submerged, but also to release a rubber dinghy, with the probability of discovery during the release process being minimized.
  • the submarine has a pressure hull.
  • the device has a storage area arranged outside the pressure hull. The storage area is designed for storing and dispensing a pressure-resistant capsule.
  • rescue devices such as life rafts, are known which are stored outside of the pressure hull and can be deployed.
  • the submarine according to the invention differs fundamentally from this, since the focus here is on minimizing the probability of discovery during the launching of the inflatable boat.
  • the capsule is designed to accommodate an inflatable boat.
  • the dinghy is compactly placed in the capsule in deflated form.
  • the inflatable boat is in a reduced pressure environment placed in the capsule, which will give a protected environment and thus longer durability for the inflatable boat.
  • the capsule is cylindrical. Cylindrical here means that the capsule is cylindrical in the central region, and the capsule has end bases at both ends, for example in the form of hemispheres. This shape makes it particularly easy to achieve compressive strength.
  • the capsule has two half-shells.
  • the half-shells have a flat connection area.
  • each half-shell correspondingly has the shape of a cylinder bisected lengthwise, with an outwardly extending connecting region being present at the edge of the half-shell. This increases the contact surface between the half-shells, and seals can also be better fitted here.
  • the two connecting areas can lie flat and along the cutting plane through the cylinder.
  • the connection area of one half shell can also reach over the connection area of the other half shell.
  • the connecting areas of the two half-shells can be designed as connecting flanges, for example.
  • the two connecting areas of the two half-shells can be connected to one another, for example, by means of adhesive, shear bolts or straps. These can also be held together under the action of force, for example when the interior is evacuated. It is also conceivable that a magnetic fixation takes place, for example. It is important that the two half-shells can be separated again by a force acting from the inside.
  • the storage area has a clamp device, the clamp device for fixing the capsule being formed in the connection area of the half-shells.
  • the clamping device preferably grips over the connection area of the upper half-shell and thus fixes the entire capsule.
  • the capsule is actively held in the storage area and can be released by actively releasing the clamping device.
  • the storage area and the capsule are connected to one another via a tether, with the storage area having a release device for the controlled release of the tether.
  • rescue capsules are known from the prior art which, once detached, appear directly on the water surface and usually unfold automatically immediately.
  • the controlled release of the tether serves to create a way to bring the capsule close to the water surface, but to be able to keep it below the water surface. Because if the capsule were to appear right up to the surface, it could easily be discovered long before the special forces also reached the water surface. Therefore, controlled buoyancy via targeted delivery of the tether through a delivery device is essential to minimize the risk of detection.
  • the dispensing device has a holding device.
  • the tether is designed to prevent release of the tether against the buoyancy of the capsule. This allows targeted waiting below the water surface in a simple form.
  • the holding device can be designed, for example, in the form of a brake.
  • the storage area is arranged in a lockable manner in the upper area of the submarine below the outer skin.
  • the storage area has a severing device for severing the tether.
  • the dispensing device is a drum, the length of tether dispensed via the drum being detected by detecting the rotation of the drum. Further, the rotation of the drum can be locked to hold a maximum payout length of the tether.
  • a tether with an exactly pre-calculated length could be used, in which case the diving depth of the submarine can no longer be subsequently varied during the launch.
  • the clamping device has at least four clamping devices, with at least two clamping devices being arranged on both sides of the capsule and with the clamping device being designed for the simultaneous release of all clamping devices. Alternatively, only the clamping devices on one side can be released first and then the clamping devices on the other side.
  • the storage area has vertical sliding elements.
  • the vertical sliding elements are used to guide the capsule when ascending from the storage area.
  • the storage area has a hatch.
  • the hatch can be closed after the inflatable boat has been set down in the submerged state. This restores the closed outer shell, which means that no turbulence occurs at the opening or open components, thus avoiding noise. This reduces the chance of detection for the sub after dropping the dinghy.
  • the submarine has an exit lock for the exit of divers in the submerged state.
  • the exit lock can be a special lock or, for example, the tower lock.
  • the exit lock can also be the weapon barrel. Divers can preferably also be picked up again through the exit lock.
  • the invention relates to a capsule, the capsule being designed to accommodate a rubber dinghy.
  • the inflatable boat is in the capsule in a deflated, compact form.
  • the inflatable boat is preferred already in zur connected to an outboard motor in a suitable manner for direct use, and more preferably the dinghy has a tank inside the capsule which is already filled with fuel.
  • the capsule is cylindrical and has two half-shells.
  • the half-shells have a flat connection area.
  • each half-shell correspondingly has the shape of a cylinder bisected lengthwise, there being an outwardly extending connecting region at the edge of the cylinder. This increases the contact surface between the half-shells, and seals can also be better fitted here.
  • the two connecting areas can lie flat and along the cutting plane through the cylinder.
  • the connection area of one half shell can also reach over the connection area of the other half shell.
  • the capsule has an inflation device for the inflatable boat.
  • the inflation device In order to be able to inflate the inflatable boat, the inflation device has an activation device arranged on the outside of the capsule.
  • the connection between the half-shells is designed to be released by inflation of the dinghy in the capsule. If the dinghy is unfolded inside by the inflation device, the two half-shells are separated and the capsule is opened.
  • the two connecting areas of the two half-shells are connected to one another by means of adhesive, shear bolts or straps, for example. These can also be held together under the action of force, for example when the interior is evacuated. It is also conceivable that a magnetic fixation takes place, for example. It is important that the two half-shells can be separated again by a force acting from the inside.
  • the inflation device has a compressed air reservoir or a compressed air generator, preferably a compressed air bottle.
  • the compressed air reservoir is connected to the inflatable boat via an inflation valve.
  • the inflation valve can be switched to open by means of the activation device.
  • the compressed air reservoir can be connected to the inflatable boat via a closure membrane, with the activation device being designed to pierce the closure membrane.
  • the activation device has an activation connection, in particular for pneumatic or hydraulic pressure.
  • the activation connection can, for example, be suitable for screwing or plugging a gas cartridge into the activation connection.
  • the activation connection can also be suitable, for example, for being connected to a diver's breathing apparatus.
  • a compressed air generating device can be connected to the activation connection, which generates a pneumatic or hydraulic pressure for activating the inflation system of the inflatable boat.
  • the activation device has a safety switch, the safety switch having to be flipped over or removed in order to reach the activation connection.
  • the safety switch also ensures that the activation connection does not get dirty and that it can be difficult to connect a gas cartridge, for example.
  • the safety switch is also watertight and pressure-resistant and attached to the activation device. By shielding the activation connection against excess pressure in the environment, accidental activation of the activation device in the event of pressure waves can be prevented.
  • the activation connection can be pressure-compensated, so that only a significant pressure difference between the connection side and the ambient pressure leads to an activation of the activation connection.
  • the activation device can be triggered remotely.
  • the activation device can be triggered mechanically in a simple manner using a simple cable or a leash or the like. This allows swimmers deploying the dinghy to stay outside of the area that is or could be occupied by the deploying dinghy.
  • the dinghy is connected to one of the half-shells with a tether.
  • the half-shell sinks after Do not inflate the dinghy directly to the ground, which is advantageous if items of equipment, such as rudders, are attached to the half-shell.
  • This tether is then preferably severed before using the dinghy in order to sink the half-shell safely.
  • a first half-shell can be connected to a tether of a submarine and a second half-shell is connected to the first half-shell with a tether.
  • the inflatable boat is preferably connected to the second half-shell with a tether and the first half-shell can also be connected to a tether of a submarine and a second half-shell is connected to the first half-shell with a tether.
  • the capsule has positive buoyancy. As a result, a safe ascent, but also not too fast and thus uncontrolled ascent, of the capsule is achieved.
  • the half-shells are made of aluminum. According to the invention, this also includes aluminum alloys and aluminum composite materials.
  • At least one half-shell has attachments for equipment on the outside.
  • items of equipment arranged there are in particular paddles, oars and the like.
  • At least one half-shell has at least one buoyancy element.
  • the half-shell has an output with the buoyancy element after detachment from the other half-shell and the dinghy. Due to the resulting downforce, the half-shell with the buoyancy element sinks ground and thus prevents later discovery.
  • a foam can preferably be used as the buoyancy element.
  • the capsule has a tightness sensor, the tightness sensor being arranged in the lower half-shell but not at the lowest point of the lower half-shell.
  • the lowest point is unsuitable, as even small amounts of condensation could falsely simulate a leak.
  • the tightness sensor is usually a moisture sensor that checks the presence of water, for example via conductivity.
  • the capsule has reinforcing elements.
  • the reinforcement elements can be designed as frames or stringers, for example.
  • the capsule is preferably diving pressure-resistant for a maximum diving depth of the submarine of at least 100 m, which corresponds to an overpressure of 10 6 Pa from the outside. More preferably, the capsule is resistant to diving pressure for a maximum diving depth of the submarine of at least 300 m, which corresponds to an overpressure of 3 ⁇ 10 6 Pa from the outside.
  • the capsule is particularly preferably pressure-resistant for a maximum diving depth of the submarine of at least 500 m, which corresponds to an overpressure of 5 ⁇ 10 6 Pa from the outside.
  • a compressive strength of more than 10 7 Pa, which corresponds to a diving depth of about 1000 m, is usually not necessary, since the submarines, which are used at diving depths greater than 1000 m, are usually not designed to deploy special forces.
  • the invention relates to a method for deploying special forces with a dinghy from a submarine according to the invention with a capsule according to the invention.
  • the procedure includes the following steps: a) evacuation of special forces, b) ascent of the special forces to the water surface, c) deployment of the capsule from the storage area of the submarine so that the capsule is held on the tether near the water surface but completely below the water surface , wherein step c) occurs independently of steps a) and b) but ends before the completion of step b), io d) further ascent of the capsule to the water surface, e) activation of the inflation device by means of the activation device arranged on the outside of the capsule, f) disconnection of the tether between the submarine and the capsule before, during or after steps d) and e).
  • step c) the capsule is deployed at a different time from the behavior of the special forces. It is only important that the capsule takes a position just below the water surface before, at the same time as or shortly after the special forces. In connection with this invention, short means a period of within 0 to 10 minutes, preferably 0 to 5 minutes, particularly preferably 0 to 2 minutes. As a result, there is no risk of discovery by objects on the water surface. At the same time, the length of stay of the special forces after emergence is minimized.
  • the further ascent of the capsule to the water surface in step d) can take place either through further controlled release of tether by the submarine. This is preferred because it enables a particularly controlled emergence.
  • the capsule can also be brought to the water surface by cutting the tether, either by the submarine or by the special forces on the capsule. The goal is to time the capsule's emergence and the combat swimmers' emergence within the tightest possible time window. In order to minimize any danger to the combat swimmers when the capsule emerges, the capsule can be brought to the water surface just before the combat swimmers reach the water surface.
  • step e) the inflation device is activated by means of the activation device arranged on the outside of the capsule, preferably by the special forces. This allows the deployment to take place when all special forces on the surface have taken up a safe position relative to the capsule.
  • the inflation device can be activated immediately after reaching the water surface, as is the case with life rafts, for example.
  • the disadvantage of this, however, is that special forces can be in the area of the unfolding rubber dinghy.
  • step e) takes place at a distance of 5 m to 25 m.
  • step e after the inflatable boat has been inflated and activated in step e), items of equipment attached to the outside of the half-shells are brought into the inflatable boat.
  • step e after the inflatable boat has been inflated and activated in step e), a connection between the inflatable boat and the half-shells is severed.
  • the half-shell or both half-shells if they are connected to each other, sunk. This avoids that the half-shells can reveal the position of the submarine or the presence of the special forces.
  • step e) activation in step e) takes place in that the special forces connect a gas cartridge, in particular a CO 2 cartridge, to the activation device and activate it in such a way that the CO 2 cartridge emits gas and an overpressure is applied to the activation device , so that the activation device is triggered.
  • a gas cartridge in particular a CO 2 cartridge
  • the CO 2 cartridge can be connected to the activation device, in particular an activation connection of the activation device, via a hose. This ensures a safe distance between the special forces and the capsule.
  • the inflatable boat is not inflated symmetrically, but initially buoyancy elements in the area of the engine are inflated and then buoyancy elements that are located further away from the engine. This ensures that the comparatively heavy motor can be kept safely afloat after the capsules have been opened.
  • additional buoyancy bodies can also be used to prevent the heavy components, for example the engine, from sinking too much. The buoyancy components are then attached to the components themselves or in the area of the heavy components on the inflatable boat.
