Abstract: A method as well as a device are provided for determining the residual travel duration of a submarine, with which firstly for at least one certain travel situation a reference journey is carried out with which the power consumption of the submarine is detected as stored as a dependent-dependent consumption profile. Later, for the same travel situation, the residual travel duration or a residual capacity of a battery given a predefined travel duration is determined on the basis of the stored consumption profile and the current battery data.

Abstract: A submarine is equipped with an extending apparatus on whose free end a container (4) resistant to underwater pressure is arranged, in which an essentially recoil-free gun (5) lies. The container (4) in the submerged condition of the submarine may be brought to the water surface (15) by way of the extending apparatus, and pivoted out so that one may also shoot in the submerged condition.

Abstract: A torque motor, especially a fuel cell torque motor, converts chemically stored energy of liquid or gaseous fuels, directly inside the torque motor while avoiding a separate installation of devices, into mechanical energy for driving at least one consumer. The torque motor is provided with fuel cells that serve as an internal energy source, the fuel cells being arranged in the stator around the rotational axis of the motor in an annular manner. The torque motor includes a rotor and stator with permanent magnets arranged on the rotor and with armature windings located in the stator. The armature windings are supplied with current from a commutator having electronic power components. Fuel cell modules and fuel cell supply and control elements are integrated in the commutator in a structurally modular-like manner.

Abstract: The present invention relates to a device for deploying ammunition, wherein a recess (2) provided in the body shell (1) of a vehicle, in particular of a ship, is covered by cover means (4), whereby a heightening of the radar signature caused by this recess (2) and having a negative effect is diminished.

Abstract: The invention relates to a method and a device for discharging signature free exhaust gas from underwater vehicles, the exhaust gas being a by-product of the production of electric energy in energy converters and being directed by means of pressure into a pipe length through which outboard water is flowing. Gas bubbles of the exhaust gas in the at least one pipe length are reduced using static mixers arranged inside of the pipe length through which water is flowing, with the gas being dissolved by the high turbulence of the fluid. As the exhaust gas is dissolved inside of the underwater vehicle, no gas bubbles that might be located are produced outside the vehicle. Since the working pressure of the method equals the immersion pressure in the pipe, the method consumes only a small amount of energy.

Abstract: A system for underwater vehicles for detecting and countering laser threats includes laser detectors and associated equipment to be placed in an underwater vehicle for providing protection of underwater vehicles. Detectors for detecting lasers are arranged on the surface of the underwater vehicle and controlled by a laser warning receiver and a signal processor. The risk of detection of the underwater submarine by laser radiation is reduced as a result thereof. Equipment for detecting and diverting objects are also arranged on the surface of the vehicle. The equipment for detecting and diverting objects are connected together and controlled by a laser control processor. The laser control processor directly communicates with a system for guiding weapons and with the laser warning receiver and signal processor.
