Title
(EN) A PITCH CONTROLLED WIND TURBINE BLADE, A WIND TURBINE AND USE HEREOF
(FR) PALE D’AÉROGÉNÉRATEUR À INCLINAISON CONTRÔLÉE, AÉROGÉNÉRATEUR ET SON UTILISATION
Abstract
(EN) The invention relates to a pitch controlled wind turbine blade (5) comprising a pressure surface side (14) and a leeward surface side (13), where the surfaces (13, 14) established a leading edge (6) and a trailing edge (7). The blade (5) comprises turbulence generating means (10) wherein said means are placed on the leeward surface sides (13) of the wind turbine blade (5) and at the outer section (OS) of the wind turbine blade (5) in direction of the blade tip (8). The invention further relates to a wind turbine (1) comprising at least two pitch controlled wind turbine blades (5) and pitch controlling means for pitching the blades (5). The blades (5) comprise turbulence generating means (10) wherein said means are placed on the leeward surface sides (13) of the wind turbine blades (5) and at the outer section (OS) of the wind turbine blades (5) in direction of the blade tips (8).
(FR) L’invention concerne une pale d’aérogénérateur à inclinaison contrôlée (5) comportant un côté de surface face au vent (14) et un côté de surface sous le vent (13), les surfaces (13, 14) créant un bord d’attaque (6) et un bord de fuite (7). La pale (5) comporte des moyens générateurs de turbulences (10), lesdits moyens étant placés sur les côtés de surface sous le vent (13) de la pale d’aérogénérateur (5), et au niveau de la section externe (OS) de la pale d’aérogénérateur (5) dans le sens du bout de pale (8). L’invention concerne en outre un aérogénérateur (1) comportant au moins deux pales d’aérogénérateur à inclinaison contrôlée (5) et un moyen de contrôle d’inclinaison pour incliner les pales (5). Les pales (5) comportent des moyens générateurs de turbulence (10), lesquels sont placés sur les côtés de surface sous le vent (13) des pales d’aérogénérateur (5) et au niveau de la section externe (OS) des pales d’aérogénérateur (5) dans le sens des bouts de pale (8).
