Abstract

La invención se refiere a una pala de rotor de turbina eólica segmentada (110), que está formada por al menos dos segmentos de pala de rotor (132, 134), donde en un área de división (130) de la pala de rotor de turbina eólica (110) dichos segmentos (132, 134) están conectados firmemente entre sí en los respectivos extremos de conexión (136, 138) por medio de una pluralidad de elementos de conexión (146), en donde se forma un espacio entre los extremos de conexión (136, 138), y un carenado (168) está unido a dichos segmentos (132, 134) en el área de división (130), el carenado (168) que cubre el espacio y los elementos de conexión (146); en el que el carenado (168) está dividido en al menos dos secciones de carenado separadas (170, 172), las secciones de carenado (170, 172) están acopladas entre sí en regiones de acoplamiento (174, 175) en el lado de presión (122) y/o en el lado de succión (124) de la pala del rotor (110) y las regiones de acoplamiento (174, 175) están separadas del borde de salida (158) o del borde de ataque (160). La invención también se refiere a un método. (Traducción automática con Google Translate, sin valor legal)
