A Flettner rotor is a smooth cylinder with disc end plates which is spun along its long axis and, as air passes at right angles across it, the Magnus effect causes an aerodynamic force to be generated in the direction perpendicular to both the long axis and the direction of airflow. The rotor sail is named after the … See more The Magnus effect is named after Gustav Magnus, the German physicist who investigated it. It describes the force generated by fluid flow over a rotating body, at right angles to both the direction of flow and the axis … See more The Flettner rotor inspired Sigurd Johannes Savonius to invent a spinning ventilation device after a collaboration between the two inventors. Anton Flettner's company … See more Rotor ships A rotor ship uses one or more Flettner rotors mounted upright. They are rotated by the ship's engines, and act like sails to propel the ship under wind power. A conventionally-powered underwater propeller may be … See more Some flying machines have been built which use the Magnus effect to create lift with a rotating cylinder at the front of a wing, allowing flight at lower horizontal speeds. An early attempt to use the Magnus effect for a heavier-than-air … See more WebThe concept of Rotor Sails was first devised by Finnish inventor and architect Sigurd Savonius in the 1920s, concurrently with German engineer Anton Flettner. Our vision is to set the standard in bringing sails back to ocean transportation, and empower shipping towards reaching the goal of zero carbon emissions. simple shoe rack diy
