Rotor Sails Technology


Flettner Rotors operate on the principle of the Magnus Effect, which is how professional sports players throw balls with a curved trajectory. Four 5m diameter by 35m high columns are mounted vertically on the deck and spin at a high rotational speed. When the wind blows and interacts with this spinning columns, it generates a pressure differential that can be oriented to propel the ship forward. The result is a reduction in mechanical power demand on the main engine, along with a corresponding reduction in main engine fuel consumption.
