Abstract
L'invention concerne un masque acoustique (30) configuré pour être agencé en regard d'une hélice (9) configurée pour tourner autour d'un axe de rotation (A), l'hélice (9) comportant une pluralité de pales (15) s'étendant radialement entre des premières extrémités appelées pieds de pales (15a), et des deuxièmes extrémités appelées têtes de pales (15b). Selon l'invention, le masque acoustique (30) étant caractérisé en ce qu'il présente au moins un élément de forme générale annulaire (31) configuré pour être agencé en regard des têtes de pales (15b) de l'hélice (9), sur une étendue supérieure ou égale à 6%, de préférence à 10%, du diamètre de l'hélice (9). L'invention concerne aussi un support (10) comprenant un tel masque acoustique (30).
