An oxide/oxide composite material turbomachine blade including a fiber reinforcement obtained by weaving a first plurality of threads and a second plurality of threads, with the threads of said first plurality of threads being arranged in successive layers and extending in the longitudinal direction of the fiber blank corresponding to the longitudinal direction of the blade is disclosed. The reinforcement is densified by a matrix, with the blade further including one or several internal channels having a coiled shape extending in the longitudinal direction of the blade.

Method for manufacturing an oxide/oxide composite material turbomachine blade provided with internal channels

A method of fabricating a part by forging, the method including: measuring geometrical characteristics of the forged part; comparing a measured shape with a theoretical shape that is to be obtained for the part; deducing therefrom zones that are not in compliance with the theoretical shape and also thicknesses of material that need to be removed from the zones that are not in compliance; and polishing the zones of the forged part that are not in compliance to remove the deduced thicknesses of material by using a controlled abrasive band. The control of the abrasive band takes account of at least one parameter representative of wear of the abrasive band during polishing of zones that are not in compliance.

Method of fabricating a part by forging and controlled polishing

A method of fabricating a metal part by selectively melting a powder, the method including: building up layer by layer on a plate and simultaneously with the part, at least one holder and support element for the part, the element being spaced apart and distinct from the part and being separated therefrom by a gap filled with non-melted powder; after the part has been made completely, removing at least some of the powder remaining in the gap between the part and the element, for example by suction, blowing, or vibration; and separating the part from the plate.
