Abstract
The invention relates to a three-dimensionally woven multilayer fibrous structure (20) having the same number of warp yarns woven at any level along the warp direction, the fibrous structure (20) comprising, in the warp direction, a first part (22) and a second part (24), the first part (22) having a thickness measured in a direction perpendicular to the warp and weft directions, greater than the second part (24), characterised in that the spacing between two weft planes along the warp direction is greater in the second part than in the first part (22), and in that the number of weft yarns is lower in the second part (24) than in the first part (22).
