International Classification:

F04D 27/00

US Classification:

415 1

Abstract:

A power generating system wherein a turbine () is mounted on top of a tower () or tethered underwater. The turbine () includes a rotor having a main blade () connected to a rotor hub () and an extender blade tip (′) attached to the main blade (). During manufacture, the optimum energy-capture is determined using site-specific conditions of one or more of air density, wind speed, extreme wind, wind shear, noise and turbulence intensity. The extender blade tip (′) is chosen from a number of extender blade tips having a length that is the closest to the determined optimum energy-capture. The chosen extender blade tip is attached to the main blade either during manufacture or on-site. Alternatively, a one piece blade is produced based on information determined from the site specific conditions. The tip of such one piece blade can be customized based on the information obtained.

International Classification:

F03B 3/14

Abstract:

A marine current turbine rotor comprises a hub and fixed and two or more pitchable blade sections configured to reduce bending moment loads on the pitch bearings and enable the use of non-standard, low-cost structural materials for the hub, blades, and pitch shaft. A submersible pitch drive mechanism or linkage in the hub rotates the pitch shaft to cause the pitchable blade section to move to a specified pitch position. The hub cavity is configured to be “wet” without the expense and maintenance requirement of seals to prevent water intrusion, utilizing water-lubricated pitch bearings.

F03D 1/06

Abstract:

The present invention relates to a wind turbine enabling a cost effective and easy attachment/replacement of rotor blades and to a method of attaching a rotor blade to a hub of a wind turbine. The wind turbine in accordance with the invention comprises a tower resting on a base, at least one rotor blade having a blade connector portion, a nacelle housing a shaft to which a hub is attached, the nacelle being mounted atop the tower. Said hub of the wind turbine comprises a plurality of hub connection flanges, each hub connection flange being adapted to be detachably connected to a blade connector portion of a rotor blade.
