Abstract
LA PRESENTE INVENTION CONCERNE UN DISPOSITIF DE RETENUE DE PALE DE ROTOR DE TURBINE EOLIENNE. DES MANCHONS DE RACCORDEMENT METALLIQUES CONCENTRIQUES INTERNE ET EXTERNE SONT RACCORDES A L'EXTREMITE INTERIEURE DU LONGERON DE LA PALE ET LES MANCHONS DE RACCORDEMENT ET LE LONGERON DE LA PALE SONT RELIES PAR UNE PREMIERE SERIE DE BOULONS ET D'ECROUS QUI PASSENT AU TRAVERS DU LONGERON. UNE DEUXIEME SERIE DE BOULONS ET D'ECROUS DISPOSES RADIALEMENT RELIENT LES MANCHONS INTERNE ET EXTERNE LEGEREMENT A L'INTERIEUR DE L'EXTREMITE DU LONGERON. L'EXTREMITE DU LONGERON EST DE DIAMETRE LEGEREMENT INFERIEUR FORMANT UNE SURFACE CONIQUE QUI AGIT ENSEMBLE AVEC LES MANCHONS INTERNE ET EXTERNE POUR PRODUIRE UN VERROU POSITIF LORSQUE LA PALE EST SOUMISE A DES FORCES CENTRIFUGES.
