Abstract

Pala de rotor para una instalación de energía eólica (1) con una longitud absoluta L que se extiende desde el empalme de la pala (11) hasta el extremo final de la pala (12) y una longitud relativa de aspa x/L que parte desde el empalme de la pala (11), estando la pala de rotor (6) subdividido en una sección longitudinal interna Li correspondiente al empalme de la pala (11) y una sección longitudinal externa Lä correspondiente al extremo final de la pala (12) y el pasaje de la sección longitudinal interna L; hacia la sección longitudinal externa Lä define el plano de sección transversal E0 y el extremo final de la pala (12) define el plano de sección transversal Ee y donde la pala de rotor (6) en relación con la longitud relativa de aspa x/L presenta en cada caso un perfil aerodinámico específico con una profundidad t, una torsión Θ , un espesor relativo d/t, un arqueado relativo f/t y un espesor relativo del borde posterior h/t, caracterizada por que el plano de sección transversal E0 con una longitud relativa de aspa x/L se sitúa en el intervalo entre 0,80 y 0,96, la profundidad de la pala t del perfil aerodinámico en el plano de sección transversal Ee es como mínimo 60 % de la profundidad de la pala t del perfil aerodinámico en el plano de sección transversal E0 y la torsión de la pala Θ del perfil aerodinámico en el plano de sección transversal Ee es mayor que la torsión de la pala Θ del perfil aerodinámico en el plano de sección transversal E0, siendo la torsión de la pala Θ del perfil aerodinámico en el plano de sección transversal EE de 3° a 5° más grande que la torsión de la pala Θ del perfil aerodinámico en el plano de sección transversal E0.
