    摘要: A first insert (15) forming a ring is placed inside and in contact with a core (10) in degradable material. On the outer face of the core a plurality of inserts (20) is arranged each comprising a platform (21) applied against the outer face of the core and at least one blade (22) extending substantially radially outwards. A fibrous structure (56) is wound around the core passing over the platforms (21) and over the inner surface of the ring-shaped insert (15). Molding of the fibrous structure, impregnated with a composition containing a resin, is performed before polymerization of the resin and removal of the core.

    摘要: An airfoil attachment including a support and flanks rising on it to delimit a broach compartment designed to receive and hold an airfoil root is provided. The flanks are machined so as to separate the portions and prevent a complete break of a flank and detachment of the airfoil when a crack develops because the crack is stopped by one of the notches.
