Abstract
An acoustic panel for a turbine engine includes a first strip and a second strip each comprising an alternation of first ridges and second ridges connected by sidewalls. The first and second strips are joined to each other to form a plurality of cells, each delimited by a first ridge of the first strip and a first ridge of the second strip. A third strip is interposed between the first strip and the second strip and includes a first lateral wall bearing on the first strip The third strip further includes at least one tab that extends inside one of the cells and delimits all or part of a passage inside the associated cell.

An acoustic panel for a turbine engine, the acoustic panel comprising:
- a first strip and a second strip, corrugated, each comprising an alternation, according to a first direction (A1), first ridges and second ridges connected by sidewalls, said first strip and said second strip being joined to each other according to a second direction (A2) transverse to the first direction (A1), so as to form a plurality of cells each delimited, in the second direction (A2), by a first ridge of the first strip and a first ridge of the second strip, each cell extending according to a third direction (A3) transverse to the first direction (A1) and to the second direction (A2), and
- a third strip interposed, in the second direction (A2), between the first strip and the second strip, the third strip comprising a first lateral wall bearing, in the second direction (A2), on the first strip, the third strip further comprising at least one tab which extends inside one of the plurality of cells, at least partially transversely to the third direction (A3) of the associated cell, said at least one tab being connected, at a first end edge in the second direction (A2), to the first lateral wall, said at least a tab delimiting all or part of a passage in the third direction (A3) inside the associated cell.
