A monolithic acoustically-treated composite structure, in particular an airflow duct (12) of an APU, comprises an internal frame assembly comprising a unitary composite frame structure (52) and at least one acoustic panel assembly (20). The unitary composite frame structure (52) defines a shape of t...
