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.

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 rotor comprises a spinning cylinder with circular end plates and, in an aircraft, spins about a spanwise horizontal axis. When the aircraft moves forward, the Magnus effect creates lift. [1] Anton Flettner, after whom the rotor is named, used it successfully as the sails of a rotor ship. He also suggested its use as a wing for a rotor airplane.
The various types of such rotor wings may be classified according to the axis of the rotor. Types include: [1] [2] Vertical-axis. Conventional rotary wings as used by modern rotorcraft. Spanwise horizontal-axis. Wing rotor: an airfoil-section horizontal-axis rotor which creates the primary lift. Magnus rotor: a rotor which creates lift via the ...
The Kaman HH-43 Huskie is a helicopter developed and produced by the American rotorcraft manufacturer Kaman Aircraft. [2] It is perhaps most distinctive for its use of twin intermeshing rotors, having been largely designed by the German aeronautical engineer Anton Flettner.
The Plymouth A-A-2004 is a rotor aircraft inspired by the Flettner rotor, a type of rotor that uses the Magnus effect to produce lift. Built specifically for Zaparka in 1930 by three anonymous American inventors, this aircraft showcased the innovative use of the Magnus effect in aviation, leading to successful flights over Long Island Sound.
The only parameter of the Flettner Rotor requiring control is the rotational speed of the rotor, meaning this method of wind propulsion requires very little operator input. In comparison to kite sails, Flettner rotors often offer considerable efficiency gains when compared to the size of a sail or kite, versus the size of the rotor and ...
