Moving blade for a turbomachine

A turbomachine moving blade without a top platform, the blade comprising a fastener root surmounted by an airfoil, the airfoil presenting an end face and pressure-side and suction-side faces, the 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 of the blade, the airfoil presenting a projecting edge at the top edge of its pressure side, the projecting edge being defined between a portion of its end face and a top portion of its pressure-side face, these portions forming between each other a mean edge angle that is strictly less than 90° so as to encourage the stream of fluid passing through the turbomachine to separate at said edge, wherein the top portion of the pressure-side face is corrugated and, in any section plane perpendicular to the main axis of the blade, follows an outline formed by an alternating succession of concave curves and convex curves.
