Abstract
A turbine wheel for a turbomachine, the disk of which comprises upstream and downstream ribs extending in the annular direction around an axis, each blade segment installed on the disk being retained by the disk in an external radial direction using upstream engagement part forming part of the segment root and cooperating with complementary upstream engagement part forming an external radial end of the upstream rib, and downstream engagement part forming part of the root and capable of cooperating with complementary downstream engagement part forming an external radial end of the downstream rib. Furthermore, the upstream and downstream ribs are movable from a separated engagement position to a close position, and vice versa, so that each blade segment can be assembled on the turbine disk.
