WIND TURBINE, HYDRAULIC SYSTEM, AIR BLEED SYSTEM AND METHOD OF CONTROLLING AT LEAST TWO WIND TURBINE BLADES

摘要

The invention relates to a wind turbine comprising rotating means including at least two wind turbine blades (4) which are turnable around the longitudinal axis of said blades, and a wind turbine hub connecting said at least two wind turbine blades (4) with at least one shaft (7, 16). Further, the wind turbine comprises hydraulic means (17) for actuating said at least two wind turbine blades (4), said hydraulic means (17) being incorporated in said rotating means. The invention also relates to a hydraulic system, an air bleed system and a method of controlling at least two wind turbine blades.
