Patent ID: 8733688

Claim:
An aircraft leading edge, comprising: an acoustic coating ( 26 ) comprising an outside surface in contact with an aerodynamic flow and an inside surface, so that said acoustic coating ( 26 ) comprises from the outside surface to the inside surface an acoustically resistive porous layer ( 28 ) that has a determined open surface ratio, the outside surface defining an aerodynamic surface; at least one alveolar structure ( 30 ); and a reflective layer ( 32 ), wherein said acoustic coating ( 26 ) integrates a frost treatment system, and said frost treatment system comprises at least one vibration emitter ( 36 ) arranged in a housing ( 38 ) that empties out at the outside surface, the housing including a flap ( 40 ) arranged to allow access to the vibration emitter ( 36 ) and to close the housing ( 38 ), the flap ( 40 ) ensuring continuity of the aerodynamic surface, and a surface area of the housing provided for the frost treatment system interfering with the aerodynamic surface is less than 10% of a surface area of the acoustic coating.
