Patent ID: 8602346

Claim:
An acoustic treatment panel comprising: a reflective layer ( 50 ); at least one alveolar structure ( 52 ); at least one acoustically resistive structure ( 54 ) that forms an aerodynamic surface, the reflective layer ( 50 ), the at least one alveolar structure ( 52 ) and the at least one acoustically resistive structure ( 54 ) being arranged from an inside to an outside of the acoustic treatment panel; and an edge of the panel which is connected to at least one second panel ( 46 ), wherein at the edge overlapping with said at least one second panel, a reinforcement ( 60 ) that is inserted between the reflective layer ( 50 ) and the acoustically resistive structure ( 54 ) forming the aerodynamic surface, whereby said reinforcement ( 60 ) ensures the uptake of forces between said layer ( 50 ) and said structure ( 54 ), the reinforcement being a section that comprises a first part ( 62 ) that offers a surface for contact with an inside surface of the reflective layer ( 50 ) and a second part ( 64 ) that offers a surface for contact with an inside surface of the acoustically resistive structure ( 54 ), and at least one wall ( 66 ) that ensures connection and the uptake of forces between said parts ( 62 , 64 ) wherein the reinforcement ( 60 ) comprises at least one crosspiece ( 68 ) that is provided between the first and second parts ( 62 , 64 ) for ensuring the uptake of compression forces.
