Abstract (en)
The drive has a propeller with wing blades, where the propeller is driven by a synchronous motor whose input power is 5 kilowatt, and has a diameter between 25 and 40 centimeters. An inclination of the blades changes in a radial direction, where the inclination such as axial inclination or radial inclination, number and cross-section profile of the blades depend on torque characteristics of the motor. An independent claim is also included for a method for optimizing a boat drive.
