摘要

The nacelle has a honeycomb panel (10) and a Herschel-Quincke tube (30) that is provided with a constant curve over its length and crossing a volume of the honeycomb panel. The Herschel-Quincke tube emerges at its two ends on an interior (120) of the nacelle through a set of perforated walls that occults two circular openings (31, 32). The set of perforated walls is provided with a sufficient level of perforation. An intermediate part of the tube is provided outside of the panel, and the tube is centered with respect to the panel.
