Definitions

  • the invention relates to a device for Buoyancy generation for underwater vehicles in the form a gas generating plant in which the chemical Reaction and / or catalytic decomposition of a liquid energy carrier buoyancy gases are generated where the liquid energy source by the pressure of a Production gas from a second Gas generating device is provided from a Storage container is pressed into a reaction chamber.
  • Such a device is known from EP 0 128 260 A1 known.
  • this known device have been proposed instead of those Gas generating plants otherwise usual use of Compressed gas nitrogen as the expulsion medium for the hydrazine a second, much smaller
  • the one Feedback and amplification device such is assigned that the blow-out time to predetermined Be adapted to the application immersion pressure can.
  • This known device is a Limitation of the maximum reasonable operational Depth of use of such generators, which at a Given the use of nitrogen as the expulsion medium and with the increasing depth requirements modern submarines are no longer compatible, avoided.
  • the object of the invention is to provide a device type mentioned so that they have a simple structure and the smallest possible mass and that they are also available in any size Diving depths compliance with the required short Expulsion times enabled.
  • the invention solves this problem by Device in which between the second Gas generating device and the reservoir for the liquid energy source a pressure relief valve is arranged, the positive pressure outlet with that with the Buoyancy gases are connected to the filling immersion cell.
  • the device according to the invention has the Advantage that their gas generation characteristics in each Diving depth remains the same, which is according to the invention provided pressure relief valve in any Immersion depth a constant pressure difference between the Production gas and the environment, i.e. the diving cell, guaranteed. Because of this constant pressure difference the constancy of the Expulsion time guaranteed. At the same time, the device according to the invention the advantage that it for any gas generation reaction can be used.
  • the invention can advantageously a number of possible Types of feed gas generators are used, that are already known on their own.
  • feed gas generators include solid fuel (powder) generators where Powder cartridges are used for gas generation.
  • Powder cartridges are used for gas generation.
  • Such Generators are used, for example, to drive Small gas turbines for the power supply of Missile use.
  • the invention must take into account that the Combustion chamber pressure must be so high that even in the greatest diving depth a supercritical outflow takes place, with which a constant at all diving depths Burning time is guaranteed; that the Fuel must be heavily under-balanced so that none Oxygen components are contained in the production gas, and that finally the combustion chamber temperature as low as possible have to be.
  • a hydrazine generator is also possible advantageously becomes a small one Ultra-high pressure generator with cold gas (nitrogen) delivery used.
  • a so-called hydrofuel generator possible at which is a water-reactive metal hydride, preferably Lithium hydride, with water to hydrogen and Metal hydroxide is implemented.
  • the water can for lowering the freezing point, for example with Lithium chloride or methyl or ethyl alcohol added become.
  • the conveying gas is advantageously cooled in the device according to the invention before it enters the container.
  • This advantageously takes the form of heat exchange cooling with the ambient water in the immersion cell, the heat exchange area required being reduced by adding coolants to the hot conveying gas jet.
  • suitable coolants are ammonia (NH 3 ) or ammonium carbonate, both of which can be used in pure form or in supersaturated aqueous solution.
  • a powder generator In the device shown in Fig. 1 for Buoyancy generation is provided by the Buoyancy gas through a powder generator. With this flows after the ignition of a powder cartridge 1 generated gas via a line 2 in a Coolant tank 3, in which a pre-cooling and a Loading with an additional gas generated here. On a pressure relief valve 4, which is a constant Pressure difference between the conveying gas and the environment of the generator guaranteed, can be excess generated gas into the environment, i.e. in this case in a diving cell 5, flow out.
  • the one for expelling hydrazine required amount of gas flows through a line 6 in a heat exchanger 7 and is in this Ambient water 8 to the required Brought temperature level.
  • the cooled gas overflows another line 9 into a hydrazine container 10, in which it acts on a bladder 11 and thereby in this container 10 located hydrazine 12th an outlet 13 in a gas generator 14 promotes where its decomposition takes place.
  • the decomposition gases are finally via outflow openings 15 into the surrounding Diving cell blown out.
  • a hydrazine generator In the device shown in Fig. 2 for Buoyancy generation is provided by the Conveying gas through a hydrazine generator.
  • compressed gas cylinder 16 delivers over Pressure reducing and regulating valve 17 a compressed gas that in a small bladder tank 18 Hydrazine 19 in a gas generator 20 promotes where it in turn is decomposed.
  • the resulting decomposition gases flow as in the case of the previous one described embodiment, again via a Line 21 through a coolant tank 3.
  • the other The path of the conveying gas corresponds to that of Pressure relief valve 4 completely the previous described arrangement.
  • a hydrofuel generator there is a waterproof, with a filled with water-reactive fuel (hydrofuel) Cartridge 22 in a generator housing 23, in which also water with a freezing point-lowering additive 24 is located, which is also the function of Coolant takes over when the production gas volume generated exceeds the stoichiometric amount. to Commissioning the generator will cover the Cartridge 22 opened so that the water can access the Hydrofuel receives and the gas generating reaction starts. As a rule, this is what is brought in here Coolant both a separate coolant tank as well as a heat exchanger aftercooler.
  • the pressure relief valve 4 also takes on the same here Function as in the case of the previously described Embodiments.
  • the further way of the gas also corresponds to that based on the previous one described embodiments shown Scheme.
  • the fuel requirement for the production of production gas by means of the device according to the invention can in estimate, if the gas temperature is as Parameter is introduced and the water vapor content of the Conveying gas according to the vapor pressure as Partial pressure assuming a temperature-dependent local condensation loss is considered an influence of coolants as possible additional gas suppliers, however, not is taken into account. Then there is a maximum Fuel requirements in the range of about 3 kilograms.
