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. The Viking Grace ferry, complete with Norsepower’s Flettner Rotor Sail S omewhere between Finland and Sweden, a ship surges through the.

Several types of rotor ships can be distinguished. Salter and John Latham proposed the building of 1, robotic rotor ships to mitigate global warming.

But the economic breeze may be freshening for sail power. Appropriate technology Clean technology Environmental design Environmental impact assessment Sustainable development Sustainable technology. The physicist Heinrich Gustav Magnus — discovered a hitherto unknown force that arises when xhip flows over a rotating body.

Flettner rotor

Flettner rotors must be mechanically driven to develop lift and propulsion power, and manoeuvrability is restricted by wind speed and direction. Flfttner Renewable Source of Energy. The rotating cylinders generating thrust mainly generate forces in the horizontal plane, forward and sideway forces. A conventional powered water propeller may or may not be provided for additional operational flexibility. The Prodigal by S. It is one of the few fuel saving technologies flertner could offer double digit percentage improvements.


The Flettner rotor principle in general is working in sideways winds, and depends on wind and vessel speed. The rotor sails will be fitted aboard the Maersk Hsip vessel during the first half ofbefore undergoing testing and data analysis at sea until the end of Cruise Business Online 22 June.

Thus, the spinning ball gets a sideways shove. The turbosail also uses a solid vertical “sail”, but uses airflow within the hollow interior to generate a force conventionally, instead of using the Magnus effect on the outside of the sail.

We look forward to using our shipping and technical expertise to support this trial. The Navy in turn sold the ship on to a new owner who dismantled its three rotors and used only its engines.

Flettner himself went off on a different tack, turning his talents for example to designing helicopters and inventing a rotating air vent for vehicles that is still in production today. Foundation attached to ship deck Lift Wind 1. Scientific Community Breakdowns of the year Scientific Community Runners-up Development Development cell by cell Scientific Community National Academies urges renewed commitment to fusion Oceanography ‘Five Deeps’ mission to explore mysterious ocean trenches Neuroscience Link to Alzheimer’s seen in nodding syndrome Table of Contents.

This force on a rotating cylinder is known as Kutta—Joukowski lift, after Martin Kutta and Nikolai Zhukovsky or Joukowskiwho first analyzed the effect. All articles with unsourced statements Articles with unsourced statements from December The young science of aerodynamics supplied Flettner with the necessary engineering data and backed up his argumentation concerning the practicability of the rotor drive. 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.


To make sure the seagoing properties of the vessel remain good, it must be prepared and planned because the healing movement influencing the stability and the strength of the cylinder foot must be properly supported as it is subject to high stresses.

The Flettner rotor deflects the wind to one side, using the resulting forces to propel the ship forward in a similar way to a sail. I am trying to establish whether the rotors are connected to the drive-shaft of the ship or do the rotors develop rofor which is transferred to the hull just as in a yacht?

E Ship 1 – Has the Flettner Rotor Ship Finally Arrived?Old Salt Blog

Most vessels burn heavy fuel oil, producing heat-trapping carbon dioxide as well as soot and sulfur compounds that contribute to acid rain. Views Read Edit View history. Time will tell whether this new take on old technology is successful.

But unlike conventional sails, the rotors can be operated by one person on their own. Container ships are not a good fit for rotor sails because their decks are stacked with containers, he notes. Picture showing the Flettner Rotor Credit:
