Abstract
A blade () for a turbomachine is provided. In at least one cross section disposed orthogonally to a longitudinal blade axis, an outer surface of the blade forms a curve (Γ) that runs continuously on the inflow side along an at least approximate ellipse (E) between a first separation point (P) and a second separation point (P). On the pressure side, the curve (Γ) has an inflection point W. A distance of the second separation point (P) from the inflection point W along the curve is at least exactly equal, at least twice as great, at least three times as great, or even at least five times as great as a distance of the second separation point (P) from the first separation point (P) along the at least approximate ellipse (E). Also described is a blade ring having at least one blade of this kind, as well as a turbomachine.
