<p>The blade has a platform (20) connecting a convex side (12) and a concave side (14) to a blade root (22). A stiffener (30) connects the platform to the root. The stiffener extends perpendicular to the platform or in circumferential direction with respect to a rotational axis of a rotor. The stiffener has a notch (40) formed at the level of a trailing edge (18), where the notch permits to provide relative flexibility to the platform. The convex side and the concave side are connected at their upstream ends by a leading edge (16), and at their downstream ends by the trailing edge (18). Independent claims are also included for the following: (A) an industrial turbine of a turbine engine, including a set of blades (B) an industrial compressor of a turbine engine, including a set of blades.</p> |
