Meaning and Definition
An aerodynamic system used to assist in steering a ship, typically a freighter or tanker, which utilizes rotating cylinders (Flettner rotors) mounted vertically on deck to generate thrust via the Magnus effect.
A system of auxiliary ship propulsion and steering that replaces or supplements traditional rudders and sometimes even main engines. It is a specific application of the Magnus effect, where wind causes a spinning cylinder to create a perpendicular force, which can be harnessed for propulsion or to aid in precise maneuvering, especially at low speeds.
