    • The invention relates to a wind turbine blade (5) comprising one or more turbulence generating strips (10), where the strips (10) are placed on a surface of the blade (5). The blade (5) is characterized in that at least one joint area (22) of the turbulence generating strips (10) and the surface of the blade (5) are completely or partially covered by sealing means (23). The invention further relates to a pitch controlled wind turbine (1) comprising at least two pitch controlled wind turbine blades (5) and pitch controlling means for pitching the blades (5). The pitch controlled wind turbine (1) is characterized in that the blades (5) comprises one or more turbulence generating strips (10), wherein at least one joint area (22) of the turbulence generating strips (10) and a surface of the blades (5) are completely or partially covered by sealing means (23).
    • 本发明涉及一种包括一个或多个湍流产生条(10)的风力涡轮机叶片(5),其中条(10)被放置在叶片(5)的表面上。 叶片(5)的特征在于,湍流产生条带(10)的至少一个接合区域(22)和叶片(5)的表面被密封装置(23)完全或部分地覆盖。 本发明还涉及一种包括至少两个俯仰控制的风力涡轮机叶片(5)和用于俯仰叶片(5)的俯仰控制装置的桨距控制风力涡轮机(1)。 桨距控制风力涡轮机(1)的特征在于,叶片(5)包括一个或多个湍流产生条(10),其中湍流产生条带(10)的至少一个接合区域(22) 叶片(5)被密封装置(23)完全或部分地覆盖。
