Abstract

L'invention concerne une pale de rotor d'éolienne comprenant un nez (11), un bord arrière (12), une zone de racine (14) pour fixer la pale de rotor à un moyeu d'une éolienne, et une pointe (13). La pale de rotor s'étend de la zone de racine (14) le long d'un axe longitudinal jusqu'à la pointe (13). La pale de rotor présente en outre une unité de distribution d'air (500) pourvue d'un organe de réglage (540) pour guider un flux d'air dans la zone du nez (11) et/ou une zone du bord arrière (12).
