Patent attributes
A turbomachine moving blade without a top platform, the blade including a fastener root (110) surmounted by an airfoil (112) that presents an end face (114), a pressure-side face (116), and a suction-side face, said fastener root and said end face being situated respectively at bottom and top ends of the blade that are spaced apart along the main axis (A) of the blade. The airfoil presents a projecting edge defined between a portion (124) of its end face and a top portion (122) of its pressure-side face, these portions forming between each other a mean edge angle that is strictly less than 90°. The top portion (122) of the pressure-side face is corrugated, and in a section plane perpendicular to the main axis of the blade, it follows an outline formed by an alternating succession of concave curves (129) and convex curves (131).
