Flettner rotor sail as explained in this video is an unconventional means of vessel propulsion and stabilization. First developed by German engineer Anton Flettner in the early 1900s, it uses a phenomenon of fluid dynamics known as the Magnus effect to propel the ship.
The Flettner sailing rotor efficiency depends on many factors, one being the type of the ship. The Flettner rotor sail technology is powered by small motor that is located within the hull, while the rotors themselves project vertically upwards for propulsion. As they rotate, the Magnus effect comes into play, and a horizontal thrust is generated to the aft of the vessel. The main source of energy is the motors that power the rotors, while the output is provided by the relative motion of the surrounding air.
The correct direction of rotation with respect to the airflow direction can enhance the Flettner rotor sial performance and efficiency as explained in this video.
