An acoustically resistive layer for an acoustic attenuation panel (22) forming a conduit in which there is an aerodynamic flow (18), adapted particularly for an aircraft turbo jet engine. The panel has at least one acoustically resistive layer (24), at least one porous structure (26) and a reflector (28) disposed opposite the incident wave. The acoustically resistive layer (24) is constituted by strips (30) disposed in the direction of the flow (18), interconnected by a plurality of splints (32) ensuring the absorption of force, particularly radially, the splints (32) having very small surfaces ensuring the continuity of the homogeneous character of the quantity of open surface of the acoustically resistive layer thus formed.
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.
