Abstract (en)
[origin: EP1555390A1] The blade has an aerodynamic surface (14), and a platform (24) connected to its base (16) via a connection zone (26). A cooling circuit extends radially between the top and the base of the blade. A part of a lower sill (34) of a discharge slit close to the platform presents a circular cross-section (40) to remove any protrusions between a reinforcement wall (32) of the slit and the connection zone. An independent claim is also included for a high-pressure turbine of a turbo machine including a set of blades.
