How does a flettner rotor work
WebThe Flettner rotor utilises this magnus effect in the form of a mechanical rotor sail. Instead of a ball, the Flettner rotor is in a cylindrical shape. When positioned in a cross wind the spinning of the cylinder by an internal motor creates a pressure difference between the bow and stern side of the cylinder, providing a forward thrust force ... WebFlettner rotor. Unconventional ship propulsor based on the Magnus effect. Flettner rotor is a vertical cylinder rotated around its axis by a motor. As wind blows past the rotating cylinder, high pressure on one side is formed with a corresponding low pressure area on the opposite side. This pressure difference generates a lift force ...
