PROBLEM TO BE SOLVED: To place blades the structure of which can be broken down into at least two parts while exhibiting a reliable mechanical behavior.SOLUTION: A blade 10 comprises: a structure 20 with aerodynamic profile and including two opposite skins 21, 22 fabricated by three-dimensional weaving of a fibrous reinforcement densified by a matrix, and a longeron 30 including a fibrous reinforcement fabricated by three-dimensional weaving and densified by a matrix, the longeron 30 including a first part 31 extending outside the structure with aerodynamic profile and designed to be connected to a drive hub for rotating the blade and a second part arranged inside the structure 20 with aerodynamic profile between the two skins 21, 22.SELECTED DRAWING: Figure 1 |
