Title (EN) WIND TURBINE BLADE COMPRISING AN AIRFOIL PROFILE
(FR) PALE D'ÉOLIENNE COMPRENANT UN PROFIL DE SURFACE PORTANTE
Abstract:
(EN) A wind turbine blade comprising an airfoil profile, the airfoil profile comprising: a suction surface and a pressure surface; a leading edge and a trailing edge and a chord extending between the leading edge and the trailing edge; a maximum thickness location between the leading edge and the trailing edge; wherein the suction surface comprises a first inflection point and a second inflection point between the maximum thickness location and the trailing edge.
(FR) L'invention concerne une pale d'éolienne comprenant un profil de surface portante qui comprend: une surface d'aspiration et une surface de pression; un bord d'attaque et un bord de fuite et une corde s'étendant entre le bord d'attaque et le bord de fuite; un emplacement d'épaisseur maximale entre le bord d'attaque et le bord de fuite; la surface d'aspiration comprenant un premier point d'inflexion et un second point d'inflexion entre l'emplacement d'épaisseur maximale et le bord de fuite.
