Patent number: 11732588Abstract: A turbomachine includes a rotor and a stator, the stator having a plurality of profiled structures, each profiled structure being elongated in a direction of elongation in which the profiled structure has a length exposed to an airflow, and having a leading edge and/or a trailing edge, at least one of which is profiled and has, in said direction of elongation, serrations defined by a succession of peaks and troughs and having a geometric pattern transformed, over at least a part of said length exposed to the airflow, by successive scaling, via multiplicative factors, in the direction of elongation and/or transverse to the direction of elongation.

Patent number: 11668196Abstract: A profiled structure for an aircraft or turbomachine is elongated in a direction in which the structure has a length exposed to an airflow and includes serrations defined by successive teeth and depressions. The serrations may be transverse to a leading edge and/or a trailing edge of the profiled structure and in the direction of elongation. Along the profiled leading edge and/or profiled trailing edge, the successive teeth and depressions may extend only over a part of the length exposed to the flow. The amplitude and/or spacing of the teeth may vary monotonically except for the few teeth nearest each end of the part, with a remaining part of the length being smooth.Type: GrantFiled: September 24, 2019Date of Patent: June 6, 2023Assignees: SAFRAN AIRCRAFT ENGINES, OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALESInventors: Fernando Gea Aguilera, Raphaël Barrier, Mathieu Simon Paul Gruber, Cyril Polacsek, Hélène Dominique Jeanne Posson
