摘要:
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.

摘要:
A power generating system wherein a turbine (34) is mounted on top of a tower (30) or tethered underwater. The turbine (34) includes a rotor having a main blade (20) connected to a rotor hub (40) and an extender blade tip (22, 22′) attached to the main blade (20). 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 (22, 22′) 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.
