Abstract

Pala de rotor de planta de energía eólica con una punta de pala (10), una raíz de pala (12), un borde de ataque (16), un borde de salida (18), un lado de presión (32), un lado de succión (30) y una sección transversal que varía desde la punta de pala (10) hacia la raíz de pala (12), presentando la pala de rotor de planta de energía eólica una velocidad específica de diseño y operándose en un funcionamiento a carga parcial preferentemente con un ángulo de paso óptimo predefinido que posibilita un consumo de potencia óptimo a partir del viento a la velocidad específica de diseño, estando formada la sección transversal por un perfil aerodinámico en el centro (14) de la pala de rotor y presentando una forma circular en la raíz de pala (12) y comprendiendo la sección transversal en una sección longitudinal de la pala de rotor, que está dispuesta entre la raíz de pala (12) y el centro (14) de la pala de rotor y que se extiende en dirección al centro (14) de la pala de rotor como máximo hasta una distancia de la raíz de pala (12), en la que el espesor de perfil relativo es de 40%, lo siguiente: - una sección de lado de presión convexa (78) que se extiende desde el borde de ataque (16) hasta un punto de inflexión (80) situado en el lado de presión, - una sección complementaria de lado de presión cóncava (82) que se conecta al punto de inflexión (80) situado en el lado de presión con una curvatura continua y se extiende hasta el borde de salida (18), - una sección de lado de succión convexa (72) que se extiende desde el borde de ataque (16) hasta un punto de doblado o inflexión (74) situado en el lado de succión, y - una sección complementaria de lado de succión (76) que se extiende desde el punto de doblado o inflexión (74) situado en el lado de succión hasta el borde de salida (18), caracterizada porque - una tangente está situada en la sección complementaria de lado de presión (82) en el borde de salida (18) y una tangente está situada en la sección complementaria de lado de succión (76) en el borde de salida (18) en la dirección del plano de rotor, si la pala de rotor presenta el ángulo de paso optimizado para el funcionamiento a carga parcial.
