  • Gas ejection duct with acoustic treatment, an aircraft, and a method of fabricating such a duct
    Patent number: 10125688
    Abstract: A gas ejection duct with acoustic treatment provided with at least one wall referred to as an “acoustic” wall for coming into contact with the gas. The acoustic wall comprises an inner skin and an outer skin that are spaced apart at least in part by a space, the acoustic wall including at least one internal mesh in the space, the mesh defining a plurality of cavities. Each cavity has the shape of a parallelepiped, each mesh extending longitudinally in a direction referred to as the “fabrication” direction that presents an acute angle greater than or equal to a predetermined angle relative to a horizontal plane, each of the inner and outer skins presenting an acute angle of inclination greater than or equal to the at least one predetermined angle relative to the horizontal plane.
