Abstract

L'invention concerne une machine éolienne. La machine comporte une hélice qui comprend un moyeu 35 monté sur un arbre d'entraînement 30 et muni de deux pattes de fixation diamétralement opposées 32, 34 auxquelles sont fixées des pales 36, 38 au moyen de deux séries d'éclisses boulonnées par pale, chaque série d'éclisses comporte plusieurs éclisses superposées de longueur progressivement réduite vers l'extérieur à partir de la pale de façon à éviter les concentrations de contraintes dans les pales. L'invention est applicable aux machines éoliennes utilisées pour mettre l'air en mouvement dans les plantations d'agrumes et éviter les effets des nappes froides stagnantes.
