Abstract: Disclosed is a power generation, distribution, and on-board power supply system for low-emission surface marine (navy) ships of different classes and sizes. The system is embodied as an equipment segment and includes at least one cruising speed drive unit, which can be supplied with electrical power from a DC network, and at least one auxiliary drive unit, e.g. a hydrojet, which can be supplied with electrical power from an AC network and can be connected as required. The DC network and the AC network are configured in such a way that power can be mutually transferred.

Abstract: Disclosed is a ship propulsion system comprising a synchronous machine (6) with an especially superconducting rotor winding that is to be subjected to intense cooling and a normally conducting stator winding (11) which is to be cooled. The stator winding (11) is disposed at least in part inside a support structure (14) encompassing a hollow cylindrical magnetically soft outer body (13) and web-type support teeth (21i) that extend in an axial and radial direction. A hollow cylindrical part (15a) of an exterior housing (15) encloses the outer body (13). In order to cool at least some areas of said housing part (15a), the stator winding (11) is thermally coupled to water as a cooling medium (K) via the support structure (14) and the housing part (15a).

Abstract: The invention relates to a high-speed, sea-going ship comprising a double hull and a water-jet drive, the latter consisting of at least one pump assembly for generating the water-jet and at least one drive motor for the pump assembly. According to the invention, the pump assembly and its drive motor are located outside the stern area of the ship by using, in part, the space in the double hull.

Abstract: An energy system, in at least one embodiment, includes an energy production device for production of energy for the energy system with the aid of an working medium, a superconductor for low-loss conduction of electrical energy in the energy system, and a cooling device for cooling of the superconductor with the aid of a liquid phase of a cooling medium. The liquid phase of the cooling medium is, according to at least one embodiment of the invention, produced in the cooling device by condensation of a gaseous phase of the cooling medium, with the condensation of the gaseous phase of the cooling medium taking place by heat transfer from the gaseous phase of the cooling medium to the working medium. The overall efficiency of the energy system can improved by the heat transfer step.

Abstract: A marine propulsion system may include at least one electric motor and a converter-fed electrical power supply. The at least one electric motor may be arranged in a propeller shaft pipe at a stern of a vessel for driving at least one vessel propeller, and may include at least one drive machine for driving at least one generator.

Abstract: A boat propulsion system includes at least one propeller, at least one electric motor by which the at least one propeller can be driven, and one converter-fed power supply unit. The at least one electric motor can be supplied with electric power by the power supply unit which includes at least one prime mover and at least one generator powered by the prime mover.

Abstract: A drive assembly for a motor vehicle comprising a forward engine supported in two bearings on the vehicle body, a rearward drive unit supported by way of at least one elastic bearing, and a central support tube arranged in-between. This central support tube is connected on the forward end with the engine in a movable manner and on the rearward end with the drive unit in a rigid manner. A drive shaft or a central corrugated shaft which has a torque-transmitting joint in the area of the connection extends in the central support tube. The engine is connected with the drive unit by way of an uncoupling device which can be adapted as a function of main excitation directions of the engine and which comprises a connecting joint which holds the engine so that it can be angular moved in the main excitation directions. The connecting joint and/or a bearing device is used for the torque support.

Abstract: A manually operable gear shift lever is disposed in a narrowly limited space with radial play on a stationary guide tube. The lower end of the gear shift lever is disposed in a pivotable ball joint. A gear shift rod leads from the gear shift lever to the transmission. The gear shift lever is disposed on the guide tube in an easily movable, durably lubricated and vibration-damping manner.
