Abstract

L'invention concerne une nacelle de turbomachine comprenant une paroi annulaire destinée à entourer au moins en partie une turbomachine, la paroi annulaire définissant avec la paroi externe de la turbomachine un conduit secondaire, la nacelle comprenant une conduite dont une première extrémité débouche au sein du conduit secondaire, et dont une deuxième extrémité débouche à l'extérieur de la nacelle, la conduite mettant le conduit secondaire en communication fluidique avec l'extérieur de la nacelle, la paroi intérieure de la conduite présentant, au niveau d'une jonction avec la paroi annulaire, une variation progressive de section transversale, l'impédance acoustique variant ainsi de façon continue entre l'intérieur du conduit secondaire et l'intérieur de la conduite.
