Rotor ship E-Ship 1. A rotor ship is a type of ship designed to use the Magnus effect for propulsion. The ship is propelled, at least in part, by large powered vertical rotors, sometimes known as rotor sails. German engineer Anton Flettner was the first to build a ship that attempted to tap this force for propulsion. "The idea worked, but the ...
The Buckau, the first vehicle to be propelled by a Flettner rotor. 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 E-Ship 1 is a Flettner ship: four large rotorsails that rise from its deck are rotated via a mechanical linkage to the ship's propellers. The sails, or Flettner rotors, aid the ship's propulsion by means of the Magnus effect – the perpendicular force that is exerted on a spinning body moving through a fluid stream.
Today the Flettner rotor is in operation as a supplemental propulsion system for transport and research vessels. [23] There are two ships utilizing the concept of the Flettner rotor in a modified form, the turbosail Acyone developed by Jacques-Yves Cousteau in 1985 and the E-Ship 1, a cargo ship that made its first voyage in 2010.
Anton Flettner's interest in aerodynamics (specifically the Magnus effect, which produces a force from a cylinder rotating in a fluid flow) also led him to invent the Flettner rotor which he used to power a Flettner ship which crossed the Atlantic, and the Flettner ventilator which is still widely used as a cooling device for buses, vans and ...

The third design considered is the Flettner rotor. This is a large cylinder mounted upright on a ship's deck and mechanically spun. The effect of this spinning area in contact with the wind flowing around it creates a thrust effect that is used to propel the ship. Flettner Rotors were invented in the 1920s and have seen limited use since then.
The Fl 184 was a two-seat autogyro with an enclosed cabin. The Fl 184 rotors had a length of 12 m and a cyclic pitch control system. The aircraft's power was supplied by a 160 PS (160 hp; 120 kW) Siemens-Halske Sh 14A radial engine that drove a two-bladed wooden propeller.
