Experimentation with Flettner rotors to aid in ship propulsion dates all the way back to the ‘s. Although the technology has not been widely. Working on a ship, the force created will generate thrust. On board vessels, such rotor propulsion are often called Flettner rotors after the German innovator who.

Flettner rotors are vertical cylinders which spin and develop lift due to the Magnus effect as the wind blows across them.

Several types of rotor ships can be distinguished. That means less electricity is required to spin the rotor, which translates into more efficient propulsion. In the shil, German physicist Heinrich Gustav Magnus noticed that when moving through air a spinning object such as a ball experiences a sideways force. It describes the force generated by fluid flow over a rotating body, at right angles to both the direction of flow and the axis of rotation. In the early 20th century, scientists proposed using the Magnus flettnwr to propel ships.

The Flettner rotor principle in general is working in sideways winds, and depends on wind and vessel speed. April 20, at 4: Working on a ship, the force created will generate thrust. The ship is propelled, at least in part, by large vertical rotorssometimes known as rotor sails.

This article has multiple issues. Ships often encounter such conditions on northern Pacific and northern Atlantic shipping routes, Riski says.

Spinning metal sails could slash fuel consumption, emissions on cargo ships

A conventional powered water propeller may or may not be provided for additional operational flexibility. Letter of intent was signed for the ship in Novemberawaiting final agreements signing in early In Norsepowera Finnish clean technology and engineering company pioneering the generation of renewable wind energy for the global maritime industry, announced that it will bring to the shp the “Norsepower Rotor Sail Solution” [21] which is a modernized version of the Flettner rotor.


The vessel was a refitted schooner which carried two cylinders or rotors about 15 metres 50 ft high, and 3 metres in diameter, driven by an electric propulsion system of 50 hp 37 kW power. Today, as oil prices threaten to rise and increasing importance is placed on renewable forms of energy, the rotating sail is gaining in relevance again.

The Magnus effect is a force acting on a spinning body in a moving airstream, which produces a force perpendicular to the direction of the airstream.

The lift developed from the rotors is transferred to the hull the the sails of a a yacht. The project will be the first installation of the wind-powered energy technology on a product tanker, and will provide insights into fuel savings and operational experience. flettnfr
