<p>The sector has a wall bounding an aerodynamic flowpath in which gases flow from an upstream region toward a downstream region, and a multiperforated plate (2) is situated on an opposite side of the aerodynamic flowpath with respect to the wall. The multiperforated plate comprises a bottom and side walls, where the distance between the wall and the bottom of the plate defining a gap is progressive in an axial direction. A value of the gap situated at the upstream region is below the value situated at the downstream region.</p> |
