Abstract: A wind turbine blade includes a plurality of boundary layer fins, aligned substantially parallel to a direction of flow over the blade, for reducing boundary layer separation from the blade.

Abstract: A blade for a wind turbine includes a chord of length “c” positioned with a leading edge tip chord angle and trailing edge tip chord angle of between approximately 45 and 75 degrees; a tip having a shear web plane radii distribution in the ranges of L/c (%) R/c (%) ?0-10% 1.03-3.68% 30-40% 2.91-5.79% 60-70% 1.77-2.5%? ?90-100% 0.229-.350%? where “L/c” is a range of an approximate normalized location along the chord line expressed as a percentage of the chord length from a leading edge of the blade; and where “R/c” is a range of an approximate normalized shear web plane tip radius expressed as a percentage of the chord length, for each normalized location L/c.

Abstract: A hatch stop for a wind turbine having an enclosure with a hatch, including a first prong arranged between an external surface of the hatch and an external surface of the enclosure.

Abstract: A sleeve for a wind turbine blade includes an opening for receiving a root end of the wind turbine blade; and an inboard edge for substantially abutting a hub of a wind turbine.
