The shroud two circular and concentric edges on each side of openings through which supply pipes pass. A row of drillings (21) are provided on a side of the shroud, where the drillings hinders formation of a resonant cavity in the volume formed in the shroud. Locations for the drillings coincide with the separation locations to restore airflow, where the flow passes from a high pressure side towards a low pressure side. |
