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