The present invention concerns a Magnus rotor comprising a drive and a control means which controls the drive in such a way that the Magnus rotor attains a peripheral speed which is greater than the mean wind speed by a factorλ. In addition the present invention concerns a method of operating a Magnus rotor comprising a drive which causes the Magnus rotor to rotate, and a control means, as well as a ship. In order better to utilize the action of the Magnus rotor than occurs in the state of the art,λis greater than 4. In that respect the present invention is based on the realization that the assumption that, above a high-speed factor of four, there would no longer be a significant increase in the lift coefficient, which above all is in relation to the drive power to be used, is based on a technical prejudice. It was possible to empirically ascertain that an increase in the high-speed factor leads to a significantly higher lift coefficient. Accordingly there is also a higher power output from the Magnus rotor. |
