Abstract

The invention relates to a vane of a guide vane or impeller blade of a turbo machine, particularly a gas turbine. The profile of said vane comprises at least one thickening that is advantageous for flow purposes in a radially inward final region and/or a radially outward final region of the vane. According to the invention, the thickening (11) is a cut in the area of a forward edge (12) of the vane so as to form a mirror surface (14, 17) or a basal plane. A fluid flow machine comprises at least one guide vane ring having a plurality of guide vanes and at least one rotor blade ring having a plurality of rotor blades, the guide vanes and the rotor blades each having blades that extend in the radial direction of a flow channel, and, at a radially inside end region and/or at a radially outside end region of the blade, the blades exhibiting a thickened portion of the blade profile that is beneficial from a standpoint of fluid mechanics, the thickened portion having a cut in an area of a leading edge of the blade forming a mirror surface or a basal plane.
