摘要

The monoblock bladed disc for turbine, comprises a central hub, a periphery blade, a first radial wing (2a), and a second radial wing (2b) between the hub and blades spaced axially on each other to allow the blades in an internal cavity. The first radial wing includes axial holes to communicate with the cavity, and is connected to external sealing rings (5, 6). The blades have hollow cavity to contact the interior blades. The disc with radial fins is present inside the cavity. The first wing or the second wing is connected to an attachment flange of the disc to gas turbine motor. Independent claims are included for: (1) a method of manufacturing the monoblock bladed disc; and (2) a turbomachine.
