摘要： The invention relates to an aircraft propeller blade including a structure having an airfoil, consisting of at least one fibrous reinforcement (200) obtained by three-dimensional weaving of threads and made denser by a matrix and a spar (60) including a bulged portion (62) extending outside of the fibrous reinforcement and forming the shank of the blade, and a shaped portion (61) in a recess (206) provided within the fibrous reinforcement (200). The fibrous reinforcement (200) comprises a disconnection area (204) forming the recess (206) inside the fibrous reinforcement (200). The disconnection area (204) leads to the lower portion (220) and the rear edge (230) of the fibrous reinforcement (200) such as to form an opening (231) for inserting the shaped portion (61) of the spar (60) into the recess (206) of the fibrous reinforcement. The opening (231) on the rear edge (230) of the fibrous reinforcement (200) extends over a height (H231) that is shorter than the height (H204) of the recess such as to provide, on said rear edge (230), a retaining portion (232) that is at least partially in contact with the shaped portion (61) of the spar (60).

摘要： A blade including a structure with aerodynamic profile including two opposite skins obtained by three-dimensional weaving of a fibrous reinforcement densified by a matrix, and a longeron including a fibrous reinforcement obtained by three-dimensional weaving and densified by a matrix, the longeron including a first part extending outside the structure with aerodynamic profile and designed to be connected to a drive hub in rotation of the blade and a second part arranged inside the structure with aerodynamic profile between the two skins. The second part of the longeron has a thickness substantially similar to that of the skins of the structure with aerodynamic profile. In addition, the fibrous reinforcement of the second part of the longeron has the same weaving armour as that of the reinforcement of the skins of the structure with aerodynamic profile.
