摘要:
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).

A marine-(navy) or commercial or yacht ship-type equipment system is for electrically driven ships having different sizes and driving power. The ships, as well as coast guard boats and customs boats, include standardized equipment segments for the propulsion and operation thereof. The individual equipment system for ship types consists of hulls, which are embodied according to the type of ship, i.e. are made according to size and specific task requirements and the equipment segments for propulsion, such as electrical oar propellers and waterjets, and for the operation of the ship such as the energy generator, the energy distributor and automation elements, are embodied according to type and according to driving power and function of the individual ships. The equipment segments are embodied in a prefabricated manner and can be installed on different areas in the hull of the ship.

A corvette ship-type equipment system includes standard-equipment segments, such as an energy generator, an energy distributor, a drive and an automation segment, and a hull which is adapted to the size and specific requirements on the corvette ship-type equipment system. In order to construct standard equipment-segments for a corvette ship-type equipment system which is technically and constructively simple and economical in terms of cost, at least one of the standard-equipment segments, such as the energy generator and/or the energy distributor and/or the drive and/or the automation segment is constructed from standard units or components which correspond to the requirements of the corvette ship-type equipment system and which are arranged in the hull of the boat and which can be built into the hull of the boat according to the different boat or ship-type equipment systems.

A fast military surface craft, particularly a frigate or a corvette, includes at least two electric rudder propeller drives, whereby the electric ruder propeller drive is placed at a cruising speed. The electric energy for the rudder propeller of the electric rudder propeller drives is generated by way of fuel cell units distributed in a de-centralized manner in the ship. At least two, preferably electric, hydrojets are provided with underwater hydrojet exit nozzles to enable the craft to travel at high speeds, whereby the electric energy of the hydrojets is produced, by generators.

A method for operation of a hybrid propulsion system for a marine vessel, including at least one electric motor and at least one internal combustion engine as drive units, is disclosed. Depending on the requirement, for example the vessel speed, the drive units individually or jointly drive at least one propulsion unit, for example a propeller, the power outputs of the drive units to the at least one propulsion unit controlled by a control device as a function of a set value, for example a set value for the propeller rotation speed or the vessel speed, and an operating mode such that the sum of these power outputs results in a total power being output to the at least one propulsion unit, with this total power output being split between the power outputs of the individual drive units as a function of the set value and the operating mode.

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.

A propulsion system for a large watercraft, e.g., for a high-speed, military surface craft, includes at least one water jet propulsion device (water jet) beneath the vessel. An operating method of such a system includes propulsive energy by combustion engines, e.g., gas turbines, and distributing the exhaust gases created by the combustion engines beneath the vessel in the water by the use of water flow of the water jet system. In such a method, the water flow speed of the water jet system is adjusted in accordance with the requirements of exhaust gas discharge and distribution.
摘要:
A propelling and driving system for boats having an outboard rudder propeller. The system provides the boat with reliable and comparatively good maneuverability. The system comprises at least two rudder propellers, each having driving motors configured in the form of a permanent magnet-excited synchronous machine. The stator winding of each synchronous machine has three winding phases connected to a three-phase alternating current, which are connected to the supply system of the boat. A modular controlling and regulating device comprising standardized modules is provided for each of the rudder propellers.
