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 win d turbine blades (4) with at least one shaft (7, 16). Further, the wind turbin e 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.
