Patent

CA 2467810

The invention relates to a method of manufacturing a hollow blade for turbine engine comprising a foot and a rotor blade, the method comprising a production stage of two external parts (14) as well as an assembling stage via diffusion bonding of these two external parts so as to obtain a blade preform. According to the invention, the production stage of the two external parts comprises, for each of these parts, the following operations: - the making via forging of a primary element (28) constituting at least a rotor blade part of the external part; - the making via forging of at least a secondary element (34) intended to form at least partially a foot part of the external part; and - the assembling of each secondary element (34) onto the primary element so as to obtain the external part.

La présente invention concerne une méthode de fabrication d'une ailette creuse d'un turbomoteur comprenant un pied et une ailette de rotor, la méthode comprenant une étape de production de deux pièces extérieures (14), de même qu'une opération d'assemblage consistant à souder par diffusion ces deux pièces extérieures afin d'obtenir une préforme d'ailette. Selon l'invention, l'étape de production des ces deux pièces comprend les opérations suivantes pour chacune desdites pièces : - la fabrication par forgeage d'un élément primaire (28) qui se compose d'au moins de l'ailette proprement dite de la pièce extérieure; la fabrication par forgeage d'au moins un second élément extérieur ( 34) destiné à former au moins partiellement le pied de la pièce extérieure; enfin l'assemblage de chaque élément secondaire (34) sur l'élément primaire afin d'obtenir la pièce extérieure finale.
