Definitions

  • the invention relates to a method for operating submerged submarines, in which cooling water is heated during operation and the heated cooling water is released to the surrounding sea at a depth that is secure against detection by infrared sensors.
  • the invention further relates to a submarine, in the operation of which heats cooling water and the heated cooling water is released to the surrounding sea at a depth which is secure against detection by infrared sensors.
  • a heat accumulator is arranged in the submarine to reduce the infrared location, in which the waste heat generated by propulsion and power generation devices can be temporarily stored so that the submarine cannot be located by means of infrared sensors by pulling a trace of warm cooling water behind it .
  • the known submarine there is the possibility, after reaching a safe water depth against the detection by infrared sensors, to replace the hot water in freely floodable rooms with cooler ambient water.
  • the invention is intended to camouflage the submarines in particular.
  • a search vehicle for example a frigate
  • a search signal for example an ultrasound signal
  • a search signal for example an ultrasound signal
  • an environmental disturbance is detected, which is caused by the submarine in its environment. This environmental disturbance can e.g. consist in a warping of the magnetic earth field or in an overlay of the natural ambient noise with own noises of the submarine.
  • a common disadvantage of these methods is that the greater the distance between the submarine and the search vehicle, the more difficult it is to locate submarines. It is known (US-A-3 526 002) to locate submarines on board an aircraft by dragging an extremely sensitive magnetic probe (nuclear magnetic resonance probe) behind it on a long line, with which the distortions caused by the submarine of the earth's magnetic field can be detected, but this location method also quickly reaches its limits, and the more so, the more modern submarines are made from non-magnetic steels. Even with this method, a semi-precise location of the submersible is only possible after crossing a certain area of the sea several times.
  • submarines for cooling the propulsion system are equipped with a cooling system in which the waste heat from the propulsion system is released to the surrounding sea water.
  • a cooling system in which the waste heat from the propulsion system is released to the surrounding sea water.
  • it is known to run lines of an internal cooling circuit of the drive along the outer shell of the submarine, so that the surrounding cold sea water runs along these lines when the submarine is moving and dissipates heat from them.
  • a small submarine generates, for example, waste heat in the order of 100 kW, so that if you allow a temperature increase of 50 ° C in the cooling water, about 2 m3 of warm cooling water will be generated per hour.
  • the heat output is significantly higher and can range up to the order of a few 100 MW, so that the amount of warm cooling water dispensed increases accordingly.
  • a submarine on a diving trip therefore pulls a trail of warm cooling water behind it, which rises to the surface of the sea due to its lower density compared to the surrounding cold sea water. This means, that a submarine in the submersible traces a trace of heated water on the surface of the sea.
  • the invention is therefore based on the object of specifying a method or a device of the type mentioned at the outset with which submarines on diving trips can be camouflaged in this respect.
  • the object on which the invention is based is achieved in that means are provided in order to bring the heated cooling water below the submarine in depth.
  • the object underlying the invention is completely achieved in this way.
  • the heated cooling water When the heated cooling water is brought from the submarine on a dive to a sufficient depth below the submarine and below the surface of the sea, then the heated cooling water then mixes with the surrounding cold sea water to such an extent that the temperature difference of the "diluted" cooling water coming to the sea surface increases the surrounding sea water is only a few mK, with the result that such a small temperature difference can no longer be recognized even with modern detection methods or can no longer be systematically distinguished from the natural temperature fluctuations on the sea surface.
  • the “heat trace” of the submarine which is on a dive trip is so far blurred that it is no longer possible to locate the submarine in this way.
  • the heated cooling water is brought into the depth by means of mechanical means.
  • This measure has the advantage that the surroundings of the submarine are not chemically influenced.
  • the submarine has, according to the invention, a filling system in which the heated cooling water can be filled in ballast containers, the weight of which in the filled state is greater than that of the amount of surrounding sea water which it displaces.
  • the ballast containers are sunk as lost good on the sea floor.
  • This measure has the advantage that the heated cooling water is disposed of undetectably by bringing the filled ballast container on board and the disposal process is thus completed.
  • the ballast containers are opened at a predetermined depth by means of a control connection and, after the heated cooling water has escaped, are taken back on board the submarine.
  • the filled and drained ballast containers are connected to the submarine via a connecting line, and a remote-controllable opening device is provided on the ballast containers.
  • ballast containers consist essentially of a plastic film. This has the advantage that very little storage space in the submarine has to be made available for the containers before filling.
  • a practical embodiment of this embodiment is characterized in that the filling system has a filling cylinder on which an endless hose is bellows-like it is postponed that the filling cylinder can be emptied intermittently into a section of the endless hose which is pulled off the filling cylinder and that means are provided for section-wise binding of the endless hose.
  • This measure has the advantage that a rapid filling of the cooling water is possible with the least possible use of material for the ballast containers.
  • a further group of exemplary embodiments of the invention is particularly preferred, in which a flexible pipeline is used as the means, which extends from the submarine down to the depth.
  • This measure has the advantage that the heated cooling water can be drained continuously even in towing operation, the depth in turn being dimensioned such that the heated cooling water emerging from the lower end of the pipeline cools sufficiently on the way to the sea surface.
  • an outlet head is arranged at the free end of the pipeline.
  • outlet head can act in the manner of a towing anchor to keep the pipeline permanently in the lowered state
  • the outlet head can also be designed so that the heated cooling water is released in all directions and / or swirled can be used to ensure optimal mixing with the surrounding cold sea water.
  • 10 designates a submarine which is diving and which is traveling in a sea 16.
  • the submarine 10 is provided with a schematically indicated drive 11.
  • the drive 11 can be a conventional electric motor, a circulating diesel or a nuclear power drive.
  • the temperature of the sea 16 is denoted by T1
  • the temperature of the submarine 10 is denoted by T2.
  • the temperature T2 is above the ambient temperature T1, because on the one hand the drive 11, but also other units of the submarine 10 generate waste heat. This waste heat is on the one hand via the outer skin of the submarine 10 to the surrounding water of the sea 16, on the other hand a cooling circuit is regularly used to cool the drive 11, which has a heat exchanger connected to the sea 16.
  • T1 + T The temperature of the train 12 is T1 + T, where T denotes an overtemperature which is smaller than the difference T2 -T1 and moreover decreases locally but also temporally with the distance from the submarine 10.
  • a cooling water outlet line is connected to a bottling plant 41 in submarine 10, the further details of which are explained below with reference to FIG. 3.
  • containers 42 are filled with the heated cooling water 43.
  • the containers 42 are designed as bags made of plastic film, which are filled at their upper end 44 and are already closed at their lower end 45. After filling the The container 42 also closes the upper end 44 and the container 42 can be let down from the submarine 10 through an opening 50 in the submarine 10 in the direction of the arrow 51.
  • a control line 55 or a connecting cable or the like is provided, with which the container 42a is held and towed at its upper end 44a.
  • a remote control for example a cable connection via the control line 55 or a wireless ultrasound connection or the like
  • an opening device (not shown in FIG. 2) at the upper end 44a of the container 42a can be actuated to open the container 42a so that the warm one Cooling water 43a can escape upward from the container 42a, as indicated by arrows 56 in FIG. 2.
  • the container 42a is of course provided with a ballast weight 52a so that the container 42a can be lowered to a predetermined depth T.
  • the container 42a After the container 42a has emptied itself, it can be taken on board the submarine 10 again by pulling in the control line 55 and filled again.
  • Fig. 3 shows further details of the filling system 41. It can be seen that a filling cylinder 60 is provided which is connected from the left to the cooling water outlet line 40, while at the opposite end of the filling cylinder 60 there is a central outlet pipe 61. An endless hose 63 is pushed onto the circumference 62 of the filling cylinder 60 like a bellows. The endless hose 63 can be partially pulled off from the circumference 62 to the right with a device (not shown in FIG. 3) and tied there, as indicated by arrows 64.
  • FIG. 4 shows yet another exemplary embodiment of the invention, in which a cooling water outlet line 70 is led out through the outer skin of the submarine 10 and merges there into a flexible pipeline 71.
  • the flexible pipe 71 extends with its lower end to the predetermined depth T and is provided there with an outlet head 72 which also acts as a ballast or as a towing anchor.
  • the outlet head 72 is provided with nozzles and / or baffle plates and the like in such a way that the heated cooling water flows out of the outlet head 72 in all directions and can optimally mix with the surrounding cold sea water.
