Shaped shaft system to reduce drag and increase the efficiency of the drive / screw in commercial ship forms (Gleit- or semi-glider hull, Verdrängerrumpf, Mehrrumpfschiffe)

摘要

The invention relates to a certain shape of the bottom of a ship in commercial shipbuilding, which shape utilises the hydrodynamic resistance by means of special shaping in order to use the volume of pressure as propulsion by means of an improved wave system. Resistance is reduced, the flow incidence on the driving propeller is optimal, and the efficiency of the driving propeller is increased without additional measures. The function is suitable for all ship and boat types, including multihull ships and boats, and for all drive systems (propeller, pod, etc.).
