Viking Grace RotorSail Increases Speed Februari 2019

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.[1] In a rotor ship the rotors stand vertically and lift is generated at right angles to the wind, to drive the ship forwards. In a rotor airplane the rotor extends sideways in place of a wing and upwards lift is generated. Viking Line #vikinggrace #vikingline #rotorsail
