Abstract

La présente invention concerne une coupole (20) destinée à un rotor d'un giravion, ladite coupole (20) comprenant une calotte (25) s'étendant radialement d'un axe de rotation en élévation (100) vers une périphérie (27) et en azimut sur 360 degrés, ladite calotte (25) s'étendant en épaisseur d'une face inférieure (31) destinée à être en regard d'un moyeu (18) du rotor (14) vers une face supérieure (32) à l'aplomb de ladite face supérieure (32). Au moins une desdites faces supérieure (32) et inférieure (31) est une face ondulée (33) qui est ondulée au moins en azimut entre la périphérie (27) et ledit axe de rotation en élévation (100) en comprenant en azimut le long d'au moins un cercle interne (90) une succession de bosses (201) et de creux (202).
