Abstract

L'invention se rapporte à une pale (10) d'éolienne comprenant: un corps (12) principal, ledit corps comprenant un bord (21) d'attaque et un bord (22) de fuite ; un volet (30) mobile par rapport au corps principal, disposé le long du bord (22) de fuite ; un dispositif (70, 120) de mise en mouvement du volet par rapport au corps principal. La pale (10) comporte un dispositif (40, 90) de guidage du volet par rapport au corps principal selon une trajectoire sensiblement orientée du bord d'attaque vers le bord de fuite, entre une position rétractée et une position déployée, une surface de la pale étant plus importante en position déployée qu'en position rétractée dudit volet.The invention relates to a wind turbine blade (10) comprising: a main body (12), said body including a leading edge (21) and a trailing edge (22); a flap (30) movable relative to the main body, disposed along the edge (22) of leakage; a device (70, 120) for moving the flap relative to the main body. The blade (10) comprises a device (40, 90) for guiding the flap relative to the main body in a substantially oriented path from the leading edge towards the trailing edge, between a retracted position and an extended position, a surface of the blade being larger in the deployed position than retracted position of said flap.
