Abstract

Les anneaux mobiles (23) d’un rotor, montés autour des disques (18) porteurs des aubes mobiles entre leurs brides (7, 37) de jonction, finissent autour des boulons d’attache (8) des disques, et sont retenus par des imbrications de reliefs complémentaires entre une nervure (24) plane par ailleurs et des faces d’extrémités en regard (22) des brides. La structure est allégée, le montage simplifié, et les concentrations de contrainte réduites. Figure pour l’abrégé : Figure 4.
