Abstract

The invention relates to a turbine wheel (100) for a turbomachine, comprising blades (120) and a disk (110) supporting them. The disk is annular and extends circumferentially around a principal axis (X). Each blade comprises a foot (124) and a blade (122) extending from the foot. The disk (110) has at least one cavity (116) formed on its periphery, configured to receive the feet of the blades. The invention is characterized in that the disk comprises a first disk (110A) and a second disk (110B). The first disk (110A) and the second disk (110B) each have at least one first cavity (116A) and a second cavity (116B) formed on their peripheries. The first and second disks are joined such that a first cavity and a second cavity at least partially form a wheel disc cavity. Figure for the abbreviation: Figure 2
