Abstract:
Acoustically resistive layer for an acoustic attenuation panel (22) forming a conduit for an aerodynamic flow (18), for an aircraft jet engine, said panel comprising at least one acoustically resistive layer (24), at least one cellular structure (26) and a reflector (28) disposed opposite the incident wave, wherein said acoustically resistive layer (24) is constituted by strips (30) disposed in the direction of said flow (18), interconnected by a plurality of splints (32) ensuring strain relief, said splints (32) having small surfaces relative to the surface of the strips (30) so as to ensure the continuity of the homogeneous character of the quantity of open surface of the acoustically resistive layer thus formed.
