Abstract

L'invention concerne un ensemble comprenant : - un carter de soufflante présentant un axe et comprenant : -- autour dudit axe, une partie annulaire fixe (13), à fixer à une nacelle, et, -- radialement à l'intérieur de ladite partie annulaire fixe (13), une partie annulaire mobile (14) déplaçable radialement par rapport à la partie annulaire fixe (13), - une soufflante (1) comprenant des aubes (10) montées tournantes autour de l'axe, dans le carter de soufflante (8), et - une source d'énergie pour faire tourner les aubes (10), caractérisé en ce que ledit déplacement de la partie annulaire mobile (14) est passif en ce qu'il résulte d'une force (F) exercée radialement de l'intérieur vers l'extérieur, contre la partie annulaire mobile (14), par les aubes (10), en tournant, sans nécessiter donc de source d'énergie pour initier ledit déplacement.
