This airflow-straightening structure for an aircraft engine (15) comprises: a hoop (31) inside which there are arranged a plurality of flow-straightening vanes (23) bearing a hub (21) of a fan (19), and a clevis (33) for connecting to a suspension strut, said clevis being fixed to said hoop (31). This structure is notable for the fact that at least two of the elements chosen from the group consisting of said hoop (31), said plurality of vanes (23), said hub (21) and said clevis (33) are formed in one piece, that is to say without any assembly operation, and for the fact that at least one of the elements chosen from the group consisting of said hoop (31), said plurality of vanes (23), said hub (21) and said clevis (33) is at least partially formed of composite material.
