Auxiliary propulsion drive for sailing yacht - uses electric motor coupled to battery recharged via IC engine, solar cells and wind or water powered turbine

摘要

The propulsion drive uses an electric motor driving a propeller screw (18), which is supplied via a rechargeable battery. The latter is selectively charged via a generator (25) driven by an i.c. engine (24) and/or via solar cells (34) and/or via a wind-, or water-powered generator (18). The battery and the first of the latter generators (25) can be used to operate auxiliary devices within the yacht, e.g. navigation, lighting, heating or cooking devices. Pref. the i.c. engine (24) and the generator are combined, the battery divided into a number of battery modules. ADVANTAGE - Reduced battery size and weight.
