Patent application number | Description | Published |
20090214343 | Turbine for a Hydroelectric Power Station - There is provided a turbine for a hydroelectric power installation. The turbine has a rotor with a plurality of blades, with the rotor being arranged in front of a guide apparatus (in the flow direction). The pitch angle of the blades of the rotor is adapted to be variable. As the rotor is arranged in front of the guide apparatus (in the flow direction) the flow meets the rotor first and only thereafter meets the guide apparatus, thus affording optimum flow conditions for the rotor. | 08-27-2009 |
20090241820 | MAGNUS ROTOR - 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 factor λ. 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 utilise the action of the Magnus rotor than occurs in the state of the art, λ is greater than 4. In that respect the present invention is based on the realisation 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. | 10-01-2009 |
