Abstract

L’invention concerne une roue de type Francis (4) pour machine hydraulique (1) destinée à être traversée par un écoulement d’eau, comprenant : -un plafond (41) fixé à un arbre (11) présentant un axe de rotation ; -une ceinture (42) ; -plusieurs aubes (43) réparties autour dudit axe de rotation et reliant le plafond (41) et la ceinture (42), chaque aube comportant un bord d’attaque (431) radial externe, dans laquelle la relation suivante est vérifiée pour au moins 40% des filets d’écoulement entre des première et deuxième aubes : Di2/Di1≥0,4, avec Di1 la distance entre les bords d’attaque (431) des première et deuxième aubes pour un même filet, et Di2 la distance entre la première aube et le bord d’attaque de la deuxième aube pour ce même filet. Figure à publier avec l’abrégé : Fig. 2
