Abstract
An airflow profiled structure having a profiled leading edge. The profiled leading edge having, along a leading edge line, a serrated profile line with a succession of teeth and depressions. The airflow profiled structure also includes a porous acoustically absorbent region located towards the bottom of the depressions.
Claims19
A profiled air flow structure comprising:
- a body having an upstream leading edge and/or a downstream trailing edge;
- porous acoustically absorbent regions;
- and
- along the upstream leading edge and/or the downstream trailing edge, a serrated profile line showing a succession of teeth and depressions,
- wherein the porous acoustically absorbent regions locally form bottoms for the depressions where the porous acoustically absorbent regions occupy a part of the body to define, together with the body, the serrated profile line at the upstream leading edge and/or the downstream trailing edge, wherein each porous acoustically absorbent region has a geometric center located downstream of the bottom of the depressions in the upstream leading edge or upstream of the bottom of the depressions in the downstream trailing edge.
