In an aircraft turbojet engine, an assembly formed by an air intake structure, a fan casing (22) and a connection piece (36), is arranged so as to reduce noise y included in the junction zone between the structure and the casing. The connecting piece (36) is fixed on a rear part (20 ') devoid of cellular core of the inner wall (20) of the air intake structure. An alveolar structure (44) internally equips the fan casing (22). The space formed inside the rear part (20 ') receives a forward extension (44') of the honeycomb structure (44), or a honeycomb structure separate from the latter. |
