TURBINE ROTOR DISK BLADE HAVING A FOOT OF CURVILINEAR SHAPE

The main object of the invention is a rotor blade (18) for a rotor disk of a turbine of an aeronautical turbomachine including, in a radial direction (23) from inside to outside, a blade foot root, a support, a platform and a rotor vane (30), where the root is connected to the support by a neck (40)...

More Information
Summary:The main object of the invention is a rotor blade (18) for a rotor disk of a turbine of an aeronautical turbomachine including, in a radial direction (23) from inside to outside, a blade foot root, a support, a platform and a rotor vane (30), where the root is connected to the support by a neck (40), characterised by the fact that the neck (40) has a curvilinear profile defining, in a section in a plane perpendicular to the radial direction (23), a curved shape, and in that the said neck section (40) thus overlaps at least 75% of the section of the rotor vane (30), as a projection of the sections of the neck (40) and of the rotor vane (30) in a plane perpendicular to the radial direction (23), where the section of the rotor vane (30) joins with the platform.
