<p>The process for fabricating a turbomachine rotor disc equipped with an annular reinforcement insert of composite material, comprises defining a metallic container (20) having an exterior and an interior annular blocks (21, 22) that are coaxially superimposed and two lateral annular side plates (23a, 23b), positioning the insert in each cavity, subjecting the whole body to a hot isostatic compacting operation to form a monoblock outline, and processing the rotor disc in the outline. The blocks and side plates delimit an annular cavity between each other. The process for fabricating a turbomachine rotor disc equipped with an annular reinforcement insert of composite material, comprises defining a metallic container (20) having an exterior and an interior annular blocks (21, 22) that are coaxially superimposed and two lateral annular side plates (23a, 23b), positioning the insert in each cavity, subjecting the whole body to a hot isostatic compacting operation to form a monoblock outline, and processing the rotor disc in the outline. The blocks and side plates delimits an annular cavity between each other. The two annular blocks are defined in a single annular block having a narrow intermediate part connecting the two annular blocks so as to form two grooves spaced axially from each other. The grooves are closed by the side plates for defining two annular cavities situated on both sides of the intermediate part. The insert is transformed into coil plates made of silicon carbide or titanium coated metal wire. The coil plates are formed to occupy the height of the cavity, and the coil plates are piled in each cavity until it is filled. The manufacturing operation comprises formation of two rotor discs having two inserts that are spaced axially from each other, formation of two distinct and connected rotor discs each having an insert, and formation of a single piece vane with each disc. Independent claims are included for: (1) a turbomachine rotor; (2) a monoblock bladed disc; and (3) a turbomachine.</p> |
