A one piece annular acoustic panel (46) is located within a recess in an internal wall (54) of the nacelle (26) . The annular acoustic panel (46) extends from a forward portion of the inlet section (34) to a forward portion of the main section (38) such that the bulkhead (42) is covered by the annular acoustic panel (46).
L'invention concerne un bloc moteur d'aéronef qui est conçu pour réduire le bruit produit par un moteur monté dans le bloc moteur. Le bloc moteur comprend un fuseau doté d'une section d'entrée et d'une section principale qui loge le moteur ainsi qu'un ensemble soufflante associé au moteur. La section d'entrée est couplée à la section principale au niveau d'une jonction de cloison principale, entre la section d'entrée et la section principale. Un panneau acoustique annulaire monobloc est monté dans un évidement, dans une paroi intérieure du fuseau. Le panneau acoustique annulaire s'étend d'une partie avant de la section intérieure à une partie avant de la section principale de sorte que le panneau acoustique annulaire recouvre la cloison.
