AUBE DE COMPRESSEUR OU DE TURBUNE A GAZ

The blade has a platform (20) including a downstream shoulder (38) that has a traversing notch (42) extending from downstream end of the shoulder towards a transversal line (44) passing through a trailing edge (18). The notch divides the shoulder into two lateral parts that expand and deform freely...

Zusammenfassung:	The blade has a platform (20) including a downstream shoulder (38) that has a traversing notch (42) extending from downstream end of the shoulder towards a transversal line (44) passing through a trailing edge (18). The notch divides the shoulder into two lateral parts that expand and deform freely with respect to each other. The notch is oriented along an airfoil section of gas flow at a convex outer side (12) of the blade. Independent claims are also included for the following: (A) a gas turbine of turbine engine, including a set of blades (B) a compressor of turbine engine, including a set of blades.
