METHOD OF MANUFACTURING A HOLLOW BLADE FOR A TURBINE ENGINE

摘要

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.
